I am not a health care worker, nor do I play one on TV. However I have worked in health care IT for 10 years. The word of caution I would inject, is in regards to the option of using a bare hand to clean the affected area. I would say this is a last resort substitute, due to the potential health risks associated with it. Hepatitis A is spread through fecal matter in food. If one is not supremely carefully, ie: wash thoroughly ( more than a minute) and then sanitize, you can spread Hep A to your self and your loved ones very easily.

Fortunately, Hep A is not fatal, mostly just uncomfortable, with a mild fever that passes and diarrhea for up to 30 days or so.

Toilet paper really is an odd invention. I believe there was a time when it was first marketed that the public thought it vaguely disgusting, and as you suggest, an unnecessary luxury.

One plausible explanation for the surge in toilet paper purchase is that in countries experiencing some form of lock down, more people work at home hence the demand from toilet paper moves from office wholesalers to retail shops and the supply chain takes time to adapt. In the mean time shelves will be empty.

There's a ruined Roman bath house near me situated on the Antonine Wall (Scotland). It has a latrine and evidence suggests they used moss to clean regio affectus.

Really great to hear you guys once again! The "HPR Audio Book Club" has been missed. Free culture audiobook reviews live!

It wasn't enough information for me to build my own quantum computer, but I did find it interesting. Looking forward to episode two.

Thanks for this episode, I love hearing how people record shows... I might have to do one of these myself!

I'm curious as to why you attenuate the bass and treble by 6dB? The final episode has a telephone-y feel to it.

Would it be possible to get hold of the original file before it's processed?

I've tried out TinyCore a few times over the years, but had no idea they made a RaspberryPi edition. What a pleasant surprise!

My partner uses hex bug (or similar) robots in her STEAM lessons (STEAM being an acronym for science, tech, engineering, art, and math), but I'd never heard of battle bots. They sound like loads of fun!

Please keep the episodes coming. You have a knack for doing episodes that exemplify the hacker ethos, while being fun and unique!

It's fascinating to hear about the "early" Internet and Internet commerce. Thank you for sharing this history.

Thanks for the info Thaj. I didn't know how to do this, but now I do. I can now be both klaatu and notklaatu on Matrix, and that's pretty satisfying.

Thank you, I'm glad you enjoyed it!
I hope I was clear enough and not too rambly. I didn't go into the monad laws because it was already difficult enough to be somewhat coherent :)

Welcome and thanks for the great first show!

You jumped directly to the deep end with a show about monads and category theory. When I saw it on the queue, I wanted to listen to it immediately. Instead I sawed it for the morning walk today so I could concentrate to it properly.

To place Serge's ideas in context, it should be pointed out first that he intended that the price paid on en e-mail would go to the recipient, which is why he said it would be a wash for most people. As a recovering economist, I do believe that anything that is provided with no charge at all is likely to be abused, and that is what we are talking about. And it is also worth noting that Serge's proposal about charging was a way to get around the only other feasible way to control abuse, which is to sharply limit who can send messages. I can, right now, write a rule that says anyone not already in my address book cannot successfully send me e-mail. I just delete on sight any e-mail from someone not in the book.

Hi Ahuka,

As you know I am enjoying the series.

I don't think that charging for messaging, however small is the answer. It is socially unfair as it imposes a financial barrier that many may not be able to afford. To quote my mother, "It's not a lot to have, but it's a lot to want". I had to send 100 applications before I got my first job, that would amount to $1 in your proposal. Now put that into context when your income is $41/month, and you see it excludes the poorest nations.

In any event it was tried with email back in the 1990/2000's and failed.
https://www.geek.com/news/yahoo-introduces-paid-for-e-mail-service-called-centmail-872762/

However it didn't stop companies in using the idea for profit.

I also have concerns on any solution that requires a verified identity in order to participate. As soon as you do, you stop been federated, and start been walled gardens. Not to mention the registration process that would be needed, and then would need to be taxed, and surely limited to authorized providers, etc etc.

I'm glad of the chance to think about this, so please keep them coming.

Hi tuturto
Many thanks for the kind words, glad you enjoyed the episode it certainly had us stumped when it happened.

All the best
MrX

@nobody, not sure what I did earlier to produce that arithmetic error, I just tried it again and your examples are working. Sorry about that.

I just did a third version:
http://www.sodface.com/misc/qots-crew-gen3

Greatly simplified, no loops and just using shuf repeatedly per nobody's example to get the first and last name.

https://pastebin.com/iaXw9ZL2

Thanks to both Dave and nobody for the feedback.

Thanks to these episodes, I realized that Chris Zimmerman was also interviewed on FLOSS Weekly #568 where he talks about Linux Bier Wanderung. I thought the voice sounded familiar, so I had to do some research, and yes, it's the same Chris from Linux Inlaws. :-)

https://twit.tv/shows/floss-weekly/episodes/568

>to see if it's more prone to do that than the awk random number generator
I doubt there is any significant difference. Certainly not any that would matter for a project like this.

>To be clear, you're not suggesting the pre/post increments work on busybox/ash correct - they don't appear to unless I'm doing it wrong:
I just threw up a Alpine container and at least there it works just fine. What command did you run that produced this error message?

> echo $((RANDOM%firstnames_len))
That's neat. The first time I tried it though I got the same number twice in a row:
m300-01:/srv$ echo $((RANDOM%100))
88
m300-01:/srv$ echo $((RANDOM%100))
88
m300-01:/srv$ echo $((RANDOM%100))
68

Probably just a fluke but I'd be interested to test it in rapid succession (eg. a loop) to see if it's more prone to do that than the awk random number generator.

To be clear, you're not suggesting the pre/post increments work on busybox/ash correct - they don't appear to unless I'm doing it wrong:

-ash: arithmetic syntax error

Also if you want the ((i++)) increment for ash you could pretty easily replicate it with:

: $((i++))

Hello!

Heard Chris Zimmermann talking about LBW in FLOSS Weekly and mentioned your podcast also was an old Outlaws listener, so started listening to your new Inlaws show now today :)

seems nice so far only listened 20 minutes

To see what tools your Busybox come with you should run it without options. Busybox is quite configurable so you should check documentation generated with the same configuration as your target. That web page is either very outdated or generated from some sample configuration.

Besides, ash also has $RANDOM so using AWK isn't really necessary:

echo $((RANDOM%firstnames_len))

Here is also a fix for Dave's suggestion:

i=1; for name in A B C; do echo "$((i++)): $name"; done

And if you use preincrement the i=1 is also unnecessary:

for name in A B C; do echo "$((++i)): $name"; done

I loved the storytelling in this one and use of sound effects. Really made my morning.

@nobody

I looked at shuf for this but it's not a busybox builtin and not included out of the box with Alpine, though awk is, which is why I went with it to generate the random number pairs. So to say that I don't know what tools are available is perhaps a little unfair as I did state in the episode that I'm limiting myself to busybox builtins. Imposing that limitation on myself is perhaps a little silly, but, it is a fact that I would have to install _something_ to get the additional functionality you reference, and that may not always be possible or desirable in embedded applications.

Actually, I wrote the above so I'll leave it there, but I decided to double check. I usually refer to https://busybox.net/BusyBox.html as a single page reference to the builtins and shuf isn't listed but /usr/bin/shuf is indeed a symlink to /bin/busybox on one of my Alpine devices, which is a little annoying. When I work on a script like this one, I usually do it on my laptop that has all the full tools on it but I double check against the busybox page to make sure I'm not using a command or an option to a command that busybox doesn't support. Then I test it on one of the devices.

I asked for a critque so I appreciate the comments!

@Dave
I don't have any _strong_ reasons for not using bash, but it boils down to:
- Most of the limited scripting I do is on Raspberry Pi and other SBC type devices, usually with Alpine Linux, which out of the box has /bin/sh as a symlink to busybox, so I work with that in lieu of installing bash.

- I sort of like the extra challenge of not using bashisms, even if it does make things a bit harder/uglier than it needs to be.

I'm at a loss to explain where I came up with the triple parentheses for incrementing i. I just tried it on busybox and two seems to work fine (though three does also). The ++ form does not (as you note it would require bash) though I'm familiar with that form, it just doesn't work within the constraints of busybox.

Forgot to actually remove the bashism... and forgot a semicolon

paste ranks.txt position.txt | while read -r x; do
printf '%s %s %sn' "$x" "$(shuf -n 1 first.txt)" "$(shuf -n 1 last.txt)"
done

The biggest problem with your scripting seems to be that you don't really know what tools are available and what options they have. My recommendation would be for you to just see what comes included with the coreutils and busybox, you'll find all kinds of wonderful little tools there.

In bash my solution to this would be this single line:

paste ./ranks.txt ./position.txt <(shuf -n 10 first.txt) <(shuf -n 10 last.txt)

If you don't mind two crewmen having two the same name then you can add -r to the shuf flags, at least when using GNU coreutils.

Since busybox' ash lacks the wonderful process substitution of bash (the <(cmd) in the above) I would probably just do something like this:

while read -r x do
printf '%s %s %sn' "$x" "$(shuf -n 1 first.txt)" "$(shuf -n 1 last.txt)"
done <(paste ranks.txt position.txt)

With larger files this ash compatible version would be quite inefficient and slow but I doubt that really matters here.

I appreciate that you are not using Bash in your script, but unless you have some strong reason not to I'd advise using it. Often 'sh' is just a restricted form of Bash!

If you agree then you can change things like:

line_num=$(printf "${crew_member}" | cut -d',' -f1)
line_num=$(printf "${crew_member}" | cut -d',' -f2)

into:

line_num="${crew_member%,*}" # gets first element
line_num="${crew_member#*,}" # gets second element

This only deals with two-element comma-separated lists so it's not quite as flexible as 'cut'.

The % provides suffix removal and # prefix removal. I covered this in show 1648 (http://hackerpublicradio.org/eps.php?id=1648)

The expression you use to increment 'i' stands out to me:

i=$((( ${i} +1 )))

Bash has pre- and post-increment arithmetic expressions and there's a compound command which lets you use:

((i++))

Look for "compound commands" and "arithmetic evaluation" in the Bash documentation. I covered some of this in http://hackerpublicradio.org/eps.php?id=1951

For example, the following one-liner sets and increments 'i' as you do:

i=1; for name in A B C; do echo "$i: $name"; ((i++)); done
1: A
2: B
3: C

What a fun and wandering conversion from 2 interesting people. Someone should get these 2 together on a regular basis. Or they should start their own HPR series. Interesting listening.

Glad the episode was helpful.

In case you missed it, there is a series "Learning Awk" on HPR which you can find here: http://hackerpublicradio.org/series.php?id=94

This has been restructured for publication on opensource.com, starting at https://opensource.com/article/19/10/intro-awk

After all these years I finally understand how you write an awk script! Thank you!

You're right! I found the same thing but forgot to mention it in either the recording or the show notes. So far all of the streams I listen to work with the http prefix, though. I seem to recall that command-line VLC (cvlc) can play streams with https but I may be wrong. I'm on my phone at the moment and can't verify.

I tried to use mpg123 with a remote stream and found the following problem on Ubuntu 19.10:

The URL MUST start with http:// and not https://, or else it looks to play a local file, and you get the error, "file access error, (code 22)". If stream redirects http to https, your stream should play. If it doesn't, you may be out of luck. For instance, I picked a random podcast on iTunes and it failed to redirect. On the other hand, using a file from HPR works just fine.

Thanks for the comment, I hope the Pi+mpg123 suits your needs. Mine is still working perfectly after about a month, though I had to update the URL for one of the streams. I love my Pi radio!

Thanks for the show. I will be trying out mpg123 on one of my pis tonight!

Thanks for the recommendation of Dark Reader. It's really great. I just would wish it would work on all the about: pages too. really shocking when you suddenly got hit by the brightness.

@Peter: All will be revealed in a future episode soon. Stay tuned! :-)

I found all of the World of Commodore episodes you've submitted to be very enjoyable. I don't have much experience with Commodores or that era of computing, and hearing what the community is currently able to achieve is fascinating

Thanks for a very good presentation on this exciting protocol. I hope this does get taken up by major sites. The old username/password stuff is not nearly secure enough, and this could be a major upgrade.

Excellent show. Love Chopin.

I loved this. I have previously supported a similar effort by Kimiko Ishizaka to record royalty-free versions of Bach. We need more free culture!

What a wonderful episode for 3000! I enjoyed this episode on my way to work. Chopin is one of my favorite composers and hearing his works just stirred my heart with emotion, especially the last two pieces. Thank you for sharing this with everyone and thank you HPR for a moving episode 3000!

Hi. Thank you for the publicity, and the HPR episode about my presentation of C64 OS at World of Commodore.

I also appreciate your comments before and after the presentation. For more information about C64 OS the official website is c64os.com.

I was very sorry to hear about the passing of your friend and fellow hacker Allison.

(http://hackerpublicradio.org/eps.php?id=2592)

there is a crack in my screen, right where my name was misspelled in that comment.. at least i am laughing this morning.

silence removal is not very kind to me... it made for good disjointed rambling though.

So good to have you back on HPR! Pretty neat story. Do you have any more like that? I'm sure others would be interested in hearing stories like that.

Again, welcome back!

Just wanted to say how much I like the episodes by Mr. Kulp.

Thank you for this episode. Your take on podcast "sponsorships," and the way this episode made me laugh has been the inspiration for many of my own recordings for HPR, DevRandom, and now The Urandom Podcast. Its been more than 10 years, and I still remember HPR #0095 fondly (if not clearly). The commercial spoofs (which are very popular with my co-hosts, and possibly even with our listener) that I do from time to time on https://random-podcast.info/ are all just an attempt to share the cynical amusement I felt when I heard Security Wow!.

Hi Gabriel, thanks for the nice comments glad you’ve enjoyed the series I do very little hacking on this projects these days but I think you are right about it never being finished. Just the other day I included a feature when downloading podcast to include in the message how many podcasts were downloaded.

Also glad you enjoyed intro music as I’ve probably already mentioned it was something I pulled together many years ago using cakewalk studio maybe version 4 and a creative labs Soundblaster AWE32 sound card. I used a midi keyboard to pull it all together. To be honest it’s been that long since I've played a keyboard I’m not sure I still can.

Anyway thanks for taking the time to comment and all the best

MrX

I guess audio editing is a lot like proof reading text for me. I need to step away from it for quite a while or else I read right through my mistakes. Reading what I meant, not what I wrote.

When I mention SRV and putting heavy strings on an old tele (breaking the nut). They were a set of 12's. I kept saying 10's.

10's are what I usually run on solid body guitars. I sometimes put 11's on hollow/semi-hollow type electrics. You won't hurt your guitar going from 9's to 10's. But, 9's to 12's, that is a bit of a jump.

BTW, I did end up putting 10's on this tele. I also pulled a bit more of the relief out of the neck. Then checked the intonation again after. I've been plying the guitar ever since. I'm not sure how quick I'll be to give it away now. Its playing sweet.

Just wanted to comment that this has been a great series. It's been fun to hear about all the ways that you've customized your podcast listening experience. At first it sounded like we'd heard it all after you covered the hardware, but listening to the options you've put in the menus, you've clearly got a lot more in there! My guess would be that you're not done either. (maybe never will be :) ) Thanks for the shows. Have always been a fan of your intro music.

Nice show! Your DIY segments remind me that we don't have to accept things as they are and don't have to be afraid of trying to make them better. Thanks for the great show!

Just wanted to comment that I'm definitely learning a lot from this series. While you've shown that there is a lot of detail to cover, you have been doling it out in nice measures. Thanks and keep it up, please!

Fantastic first episode. Delivery definitely didn't sound wooden! I love the LISP family as well, but this episode was the first time I've heard someone talk about the unique power REPLs in the development environment. My editors have always been very basic and never head the interpreters embedded. I may have been missing out all this time! So thanks for showing something new to try out!

Hey lostinbronx,

Just wanted to let you know that I really enjoyed listening to this series. I'm a long-time RPG player, but can't say I've ever done a space opera game. This was really more due to lack of friends w/ similar interests than lack of interest on my part. Well that land lack of hours in a day. :) It was fun to listen to and at times want to yell through the speakers "no no, don't do that, do this!". That included a few of the rule suggestions. I, like you, enjoy systems that get out of the way of the storytelling. (though I still like some "crunch" to them)

Anyway, thanks for the chance to listen to another foray into the Stardrifter Universe.

Hey Dave,

I've been behind on my listening too. Glad to hear that you liked the scripts and thanks for the feedback!

Thanks for this Paul. A great first show and some interesting interviews.

I never owned a Commodore computer but I worked in a university that had many of them. I remember visiting one of the engineering departments in the early 1980's which had a lab full of Commodore PETs. I was impressed by the way the top of the case, with the monitor attached, could be lifted up and kept in position - like working on the engine of a car!

I bought a BBC Model B for my own use around that time. This was another 6502-based machine, which was very popular in the UK. My workplace ended up with lots of these too.

Looking forward to hearing your further episodes on this subject!

Thanks for a really interesting first episode! I don't have a history with Commodores (apart from a 1981 novelty belt buckle with a PET computer on it) but this sounds like a fun event and I geek out on old technology. Thanks for including pictures. Looking forward to more episodes!

Hi Beni,

I remember Macsyma, the predecessor of Maxima. We used to run it on the VAXCluster at the university where I worked, for use by Maths students.

Your project sounds very cool, wrangling Maxima to receive and process algebra. I'm mathematically challenged, but I spent a fair bit of my working life in IT writing "glue" code to make bits of software talk to one another. This sounds like quite an undertaking!

Good luck with it, Dave

Interesting info. I remember in the early 90s watching the WWF with my dad. Now I know why they changed the name to WWE! The panda won the fight.

Ken, I know I don't sound so bald-headed on the radio. People are always surprised by this when we meet F2F.

This is looking really good! I wish I'd known about the affordable torch you're using when I was building mine. I would definitely have bought one and probably sped up my completion b/c I kept having to wait for our metal shop to be open at a time I could go. It was especially nice to hear your reaction to learning how to braze weld because as a novice I went through the same series of emotions, kind of scared at first and completely stoked after a couple successful joints. It's very empowering to learn something like this, isn't it? Looking forward to the next episode.

I did not know what a the name of a Bolo was.

Who is the guy modelling the ties, because he looks nothing like Jon Kulp in my head.

Thanks very much for making and posting this. I massively enjoyed listening, even if nearly everything about it is and will be out of reach for me for the foreseeable future. (I'm a city creature and nothing resembling brazing is happening in any of my spaces any time soon.)

I listened to this on my phone with only the benefit of the title on the screen and not the show notes. And I have to say, I was fully expecting that "bespoke bike building" was referring to a bespoke building to house bikes, or a [bike shed](https://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/misc.html#bikeshed-painting).

Dag nabbit! I just sent another one

Hi Daniel...
Many thanks for a great epsiode. I have been dabbling in numerical analysis in Python for a few weeks. I think this is an area I would like to explore next.
Will check out your YT for sure.

Great show, Ken. I've been minimally involved in GPodder.net since Stefan first made his announcements. Actually, I was the one that put his original post on the Jupiter Broadcasting and Ubuntu Podcast telegram channels.

I've been looking for a way to contribute more, and I think this show has provided me an answer (data management stuff). I'm already on the slack channel, so I'll contact them directly.

Keep up the good work.

That said anyone planning a episode could add a comment or ping the maillist.

Of course that would qualify as "I owe you a show"

Speaking of the HPR Book Club ...

I can do that, though it requires that I have the next one lined up in advance. That's a lot of organization! And, of course, this is not an exclusive series; anyone can post a review, and do it in any way they like.

Hi LnB,

Great episode and great series. Can I ask that you include the link to the next movie in the previous one as it would be nice to have the ability to play along.

Just like they do with the HPR Book Club.

Speaking of the Book Club.....

I'm really glad you found this useful. A fact not widely known in these parts is that I was once a financial manager, so I think my own experience factored into this. I love that these tutorials are still useful for people.

Hi Ahuka
I just wanted to let you know that I use this template _A_LOT_.
I never studied business at school or even computing. I guess that I taught myself the basics of both over the years.
I like the nice clean, simple layout of your template and have presented it along with proposals to business professionals. I even received a comment from an asset finance manager that they liked how clear the information had been laid out and presented without "fluff" trying to sugar coat figures.
So here I am again grabbing a clean template for another project. :-)

Thanks again.

Welcome to the HPR Host Crew! This was a great first episode. I look forward to you next one.

Hi Gabriel,

It's been a busy month and I have only just caught up with this show.

I'm amazed by what you have done here. I was running the script while my family were visiting and could see them checking Reddit and YouTube, etc! I could see my main router doing its thing, and my secondary router (being used mainly as a wireless access point and Ethernet switch) also doing what it does. I was impressed the display showed the names I had allocated in /etc/hosts ;-)

Now they have left it's all a lot quieter with my mail client checking various mail feeds and Mastodon updating itself. Fascinating!

I had a fairly detailed look at your Bash and Awk scripts. Impressive. I shall look further later. As you say, Perl would perhaps be better, but it's great to see how powerful (and lightweight) sed and awk can be.

Thanks for putting this together. I really enjoyed this episode.

Dave

I have been a fan of LISPs for years. I haven't considered playing with Clojure until you mentioned it, so that's the next plan.
Great first episode.
TY
gerry

I thought this was a great episode and the reading didn't bother me at all, your enthusiasm for lisps still came through. Made me want to check into one of them!

Interesting ideas. I really enjoyed this episode and got a bit emotional at the end, which was unexpected.

I haven't rewatched all the movies myself but when I do, and I hope I will with my son at some point, it will be in Machete Order (so named because it was first described on the nomachetejuggling blog).

The explanation why is full of spoilers and you can find it online. In short, it takes the journey of one soul, reexamines it through the story of another, then joins the stories in a grand finale.

The order is: IV V II III VI and then episode order from then on. It papers over some of Lucas's worst narrative mistakes and ruins none of the surprises except one.

If this seems silly, then release order. The prequels require original trilogy (TOT) knowledge to fully enjoy, and they ruin important surprises in TOT, so episode order is just not the way.

Welcome and thanks for the great first episode.

Like you said, lisps are super-powerful languages that are fun to program with. I feel like lisp is perfect language to write the language you will use to solve your problem with.

When I was coding in lisp (for hobby), I often wrote my program in language I wished I had and then added needed features to language I had with macros.

Great episode on Mastodon and the various instances.

BTW, I heard that you noticed the interface looked like Tweetdeck. You can change that if you go into Preferences-->Appearance and uncheck the box for the "Enable advanced web interface". This will make the interface much simpler with only the column of the timeline you've chosen (Home, Notifications, Local timeline, or Federated timeline) on the list at the right of the page. The instance I'm on (mastodon.xyz) is running version 2.9.3 of Mastodon, so anything at that version or greater should have this option.

As a result of this show there is now an "⇧Upload⇧" button on every page.

Thanks for holding it down solo this month, Ken! And yes I did think of using a potentiometer instead of a resistor, but this clock's case didn't have much wiggle room and I wasn't up for anything more challenging. A volume knob for the alarm would be fantastic, for sure.

Can you go into how it works with relation to working as a part time fire-fighter.
How often were you called out ?
Are there laws obliging companies to give you the time off ?
What happens if you get injured - who pays the unemployment benefit (WW uitkering) ? Can you get fired from your main job ?

I think this the video you refereed to "Backdraft training" by Keith Thomas

2400 liters per second is 2.4 m^3/s (cubic meters per second) or 84,76 ft³/s or 634,01 gallons_per_second_us_liquid

For my part, Ken's reading of the opening info is far, far better than espeak. Then again, a screaming cat would be better. I've brought up what an incredible turn-off that espeak intro is to new listeners on the email list before, and was hooted down. But, if you're asking for opinions, well, this is mine.

b-yeezi, hearing that you were able to follow Haskell structure and syntax made me extremely happy! It's quite alien looking language with odd syntax and explaining it in podcast is pretty hard for me.

Markov chains (and other procedural generation methods) are close to my heart as I have been tinkering with games for a long time. I rather try and write algorithm that generates me content and be surprised by the results than write it by myself and know exactly what to expect.

I may be in the minority, but I love thinking about Markov Chains and other probabilistic algorithms. It is interesting how this is implemented in Haskell. Comparing it to the same algorithm in Python allowed me to follow Haskell structure and syntax for the first time.

hi Jeroen, After meeting you at Oggcamp19, it is great to put a face to the voice, hope the talk went well on the Sunday, also after meeting you and Yannick (and the crew at the HPR stand) I am inspired to look and see if there is anything I can do a podcast about (so I can contribute back to the community). Take care my friend and thank you for sharing your experiences in such an enjoyable/informative way.

I posted this over at the memorial wall for his obituary, but it probably bears repeating here.

I knew him by his online handle, 5150. He was simply a great, great guy. A fine podcaster, and tireless member of the Hacker Public Radio community, among others.

He offered encouragement by the bucketful, and constructive criticism where needed. A good soul, and a man of strong character, who displayed loyalty and dependability each time I spoke with him.

I never met the man, but Fifty was my good friend.

May he rest well.

I agree with Jezra, this was tons of fun.

stinging nettles, and cobwebs, and badgers! :)

Thanks for another top episode, Gabriel. Though I am pretty experienced in this field, I stil find this stuff fascinating & educational.
I have finally gotten round to downloading ONICS and look forward to playing with it.

Hey b-yeezi, just wanted to say that I really enjoyed this one. The topic of data analysis is definitely fascinating. Clearly, from your comments, some folks don't have data mining or data science in mind when they build applications, but this episode gives one a very strong notion of why everyone should.

Hey, thanks for the feedback. I'll try to continue to build on the "fundamentals" as the series continues.

I don't have any plans to cover Okuna. Maybe you can do a show on that.

Hi Jezra.

I use a Wireless ISP in Shropshire, a rural county in England. The signal is bounced between relays mounted on the hilltops and beamed down to villages and farms below. The "line of sight" problem is resolved by having a few low power sub-relays positioned around the area at lower elevations. For example, I cannot see my nearest relay from the roof of my house, but a grain silo on the farm next door can, so I take my signal from a sub-relay mounted on top of the silo. It works great and, since the ISP is only a small company it must be quite cheap too.

Perhaps one of the WISPs in your area could be persuaded to look into this approach to expand their customer base.

Hi,

I really loved to listen too this show and learned a thing or two.

As one of the sponsors of the Okuna (previously Openbook) kickstarter project I really look forward to your review of this in one of your shows if you ever find time or interest.

Kind regards,
Jeroen Baten

No pressure.

Really enjoyed the episode. I've known about Chocolatey for some years now and it's been a godsend for me when I have to use Windows at work (I primarily use Linux and OpenBSD). I actually have a scheduled task that runs the "cup all -y" command daily (this command sequence upgrades all packages installed via Chocolatey and accepts all prompts). I also use MSYS2 for a proper Unix-like shell with pacman for running updates so that I can use all the CLI apps I use on Linux/OpenBSD. PSTools is another suite of tools that I can't live without.

Ultimately, one needs to use the tools that work for them, whatever that is. If it's Windows or macOS, great. If it's Linux or a BSD or something completely different, great. If it's TempleOS, I'll have to raise an eyebrow, but still, great. :-)

Hello Jon,

late comment, but I have a huge lag in listening.

One more explanation of the muffled sound when playing back at quarter speed, is the inherent low path filtering of the process of getting the sound on the reel. Assume, the original track contains tones in the 10 kHz range, these become 40kHz tones in the sped up version. When playing the quick version to record them on tape, the player has to correctly reproduce those high pitched tones and the recorder has to be able to bring those to tape. Depending on the frequency response of this chain, I expect this to be the bottle neck. When playing at quarter speed, the highest pitch you will get is only a fourth of the highest frequency the recorder could handle.

Regards,
Michael

I am enjoying this series, the banter between everyone is pretty cool.

I really hope this takes off. I would be a great addition to the next Raspberry Pi edition.

Way above my head, but great show.

If I was not already on Mastodon, this would be an enticing move.

I want to say that this is a very interesting topic. I may not understand it all, but there are many people here who would take well to this subject. Keep it up.

Really clever way of doing this. When I saw the headline, my mind started immediately working through all kinds of algorithms one could use shortening urls. Turns out, nothing complicated is needed.

You've said that you are a volunteer fire fighter. I'm wondering if most fire firefighters in the Netherlands are volunteers. In the US there are volunteer departments for sure in rural and small town areas. But most of the medium to larger cities have fire departments where the fire fighters are employees of the city or county.

Thanks for cluing us in on the source, Timttmy.

Jon, these things are a trick. I really think some manufacturer orders 10,000+ of these from China, assembled, then brands them all for resale.

The factory making them might as well sell a kit with all the parts and make some money on the side. :P

However, you're left on your own to figure the thing out.

Then again I do like a challenge. It was a fun project.

As someone who's just started working on a general adult psychiatry ward I really appreciated hearing what it was like on the other side of the curtain.

I will never claim to understand what it's like to have such a condition but I feel like I have a better idea. One thing we are taught is that patients with schizophrenia are more often scared than anything else (before angry, violent, dangerous, manipulative, whatever negative preconception you want to put in) and your podcast has really confirmed that for me!

Thank you!

Bill! Thank you so much for closing the loop on this project. You really left us hanging with part 1 of it. Very glad to hear that you got it working.

I'm sorry to report that I ordered a similar kit from China for a digital delay pedal for about $20, and after assembling it, all I got was a loud hum and couldn't even get the case to close right. I don't think I'm cut out for assembling small electronics. The "instructions" were exactly like yours, simply a photocopy of the circuit board without any real instructions.

Just walked around the neighbourhood and all four have a parked over it. I was hoping that the solution to covered hydrants was to crush the cars, but alas.

Hi NYbill
Glad to hear you got the trem pedal working.
It came from ebay. If anyone wants to try and build one just search for.
DIY Tremolo Pedal All Kit With 3PDT Switch and 1590B
I may grab one for myself but first I've got to finish rebuilding my guitar.

I was slightly shocked at being there on my own, but I have "ridden shotgun" a few times now and have done a few shows with other co-hosts, so I didn't panic ;-)

I'm glad it turned out tolerably well, and now that Ken has been released by the Dutch Mafia/Yakuza/aliens we'll hopefully be back to normal next time!

Great job on the Community News, Dave. Thanks for stepping up and flying solo.

I ran out of gas! I got a flat tire! I didn’t have change for cab fare! I lost my tux at the cleaners! I locked my keys in the car! An old friend came in from out of town! Someone stole my car! There was an earthquake! A terrible flood! Locusts! IT WASN’T MY FAULT, I SWEAR TO GOD!

Thank you, Ken! Combined with youtube-dl, one can pretty much acquire every single piece of music one has ever wanted in a single night with this. You've sped up my workflow considerably. Also great for breaking podcasts into chunks, if like me, one has a car stereo with an incredibly slow fast-forward/rewind function.

Hi Ahuka,

I always enjoy your reports from Penguicon. This one was great!

As to your reflection on the pronunciation of the word "solder" I have a few remarks:

- The word is derived from the Latin "solidare" - to make solid

- Yes, the British do generally pronounce it to rhyme with "colder" and "folder". This seems to make sense given that its form is very similar. Pronouncing "folder" as "fodder", even in dialect, would be very confusing, for example.

- The French equivalent is "souder", which sounds (to my ears) like "sooday".

- I have seen it suggested that the USA pronunciation is derived from the French.

Language is fun! I recently bought a Chinese hot air soldering gun (SMD Rework Station) from Amazon. I particularly like the legend on the box which says:

"Soft and spiral wind can welds all chips"

Words to live by ;-)

I was listening to this with a big smile on my face. It was great fun to hear you actually create this piece of craftmanship!

http://hackerpublicradio.org/rss-future.php

I'm sitting on edge of my seat, waiting to have more of this to listen to. Interesting topic and very close to my heart.

Thanks for the feedback Dave, and glad that this installation went more smoothly than the last one. Next episode is in and I've scripted about half of the one to follow.

Hey McNalu that’d be great to hear you do a show about your 4-track! One of the things mine **can’t** do is bounce multiple tracks down to one and free up tracks for more. The Porta 02 is REALLY minimal. Bouncing is a key feature of typical 4-tracks and it would fill a significant gap in my coverage if you talked about that for us. I’d love to hear that.

Loved this show. I had a four track which was a model up from this I think - a Portasound 04. I got it in 1987 or 1988 and recorded a lot of music on it and pushed it to its absolute limit by bouncing tracks. In fact I still have that four track and all the cassettes so I promise herewith to dig it out from the back of the cupboard and see if it works in an upcoming HPR show. Thanks Jon, superb stuff!

Thanks for the comments,y'all. There's no sheet music as far as I'm aware. I sat down and wrote out a chord sheet about 10 minutes before I started recording haha! I've been doing this a long time and it's not a very hard song. It does have one strange chord progression that I had to think about a couple of times before I figured it out, but otherwise it's pretty easy. I also ran through the melody a couple of times on the harmonica. It was fun. Maybe sometime I'll do a proper job of it and make a recording without annoying mess-ups that can actually be used as the outro music.

What a fun episode. Thank you. Did you determine the HPR melody by ear, or did you happen to stumble upon some sheet music?

Thanks for the shoutout, Ken. I love this clever use of the silence finder. I’ve never tried this but definitely will next time I’m transferring an LP. Nicely done!

I installed ONICS after your first show about it but didn't use it much. I haven't had a great need to do network monitoring or troubleshooting in the interim.

I reinstalled after this show and followed along with your examples and found them very helpful. The capabilities of ONICS seem very impressive. I'm looking forward to hearing more!

Dave

This was really great episode to listen to. Reminded me of times when we messed around with 4 tracks as students.

Thank you so much for this episode, I've never heard someone go through this process, it was wonderful to go along the ride with you.

Hi Windigo,

Great show. I loved the detail and the ambient sounds.

I was preparing a giant batch of ratatouille as I listened - for my kids who don't live with me, but for whom I make dinner two to three nights each week.

Hearing you taking the picture I dashed to the notes to look at it but ... nothing!!

Still, the meal sounded great.

Best wishes,
Dave

Thanks Bookewyrmm, I will definitely give that a try!

Thank you for your thoughts! I started listening thinking I would agree, but I didn't.

Vulnerabilities do not generally come in through technical details like what style of linking is used. Your attack surface remains the same. Vendoring the code doesn't help either, that's just a distribution and versioning issue.

The only real way to reduce dependencies is to reduce them; Write the code ourselves, or make sure we fully understand our dependencies.

Here's an article that goes further into this: https://medium.com/@kori/systems-easily-understandable-by-one-person-f92e8613e2e

Many times if you know there is too much salt, (especially in soup) you can add a 1/2 of a peeled potato and it will absorb the salt. The potato can be either cooked and eaten or discarded.

Mike and dodddummy, I'm, completly on your side. But you know, you can fastforward. It's not the first time you get such opinions on the NYE-show and nowadays I just jump to the next 10-minute-chunk and if necessary the next, because it's not worth wasting lifetime to listen to it and get upset.

And by the way, I do not accept that morality is in decline because of the decline in Church going or church going values. Church goers do not have a monopoly on morality. I have never set foot in a church voluntarily in all my 55 years, but I have a very strong sense of right and rong.

Some of the things I regard as wrong...shooting people, telling non-whites who were born here to "go back where you came from", sexually assaulting small boys left in my charge, demanding money with evangelical menaces to fund my private jets, refusing to teach evolution in schools, denying the poorest in society medical care to keep taxes for the richest as low as possible

I understand it is normal in the USA now for many schools to drill the kids on what to do in the event of an active shooter.

Any society where that is necessary has a fundamental problem.

There is no justification for the private ownership of automatic or semi automatic weapons.

And we could all stay silent on the subject of the far right and routinely homophobic, Islamophobic, sexist morons taking over power. But what is that quote? All it takes for evil to flourish is for good men to do nothing. That is a quote so I make no apology for the masculine 'men'. It equally applies to any gender nowadays.

I believe that part of the constitution that enshrines 'the right to bare arms' was written before repeating weapons even existed. So that part is no longer fit for purpose.

Here in the UK even owning a hand gun will get you four years in prison, even before you use it to commit any fellony. And we have not had a mass shooting since the 1996 Dunblane massacre that lead to the changes in the law.

We are certainly not telling our kids "run, tell, hide" or otherwise drilling them on what to do in the event that anything more serious than the wheels falling of the bus occurs

'Leftpondian'. Person who is on the eastern side of the Atlantic, IOW, an American. As opposed to a 'Rightpondian', a person on the eastern side of 'the pond', IOW a European. Not meant as an insult, just a common idiiom.

You know, Europe, that place where we have no 'right to bare arms' which was written when all guns fired a single shot and then took a minute or so to reload, or when the people you were busy slaughtering in their millions were keen to kill you.

A time when there were no shopping malls and no enclosed school or college campuses which are easy targets for some evil nutter with an assault rifle, which he or she got out of a vending machine, or so it seems.

Words that are no longer fit for purpose.

Can't buy a Kinder Egg, it's a choking hazard to the toddler on the back seat of the car, sitting next to mom's purse, from where he/she can so easily pluck her gun and shoot her in the back of the head.

1987, Federal government ban steel tipped lawn darts after just ONE toddler is killed by one. But don't take away our right to pack war hardware just in case we have to stop the odd racoon pitching over the dumpsters, despite thousands of young and old alike being killed year on year for no better reason than the power of the gun lobby

'The best thing to stop a bad guy with a gun is a good guy with a gun.' Don't see many examples of this happening

What is a leftpodian?

In countries where it is difficult to get guns there are fewer mass shootings, however, there is not less violence. The vehicle for the violence is different. Not the violence.

I saw one commentator of Fox blame video games, and a number of others ignore or question that belief. Sadly you can't believe anything you see on TV as a whole any more.

Japan is a culture with deeper roots in family and the importance of morality. They don't necessarily agree with the "to each their own" adage that western society loves. They openly shame anything and anyone that does not fit their norm. Societal acceptance is a major driving force in all that they do. Perhaps that is what is missing? A society enforced moral code and shaming when you don't fit in the box? Is that what we should go back to?

I don't condone and it isn't easy for a teenager to buy alcohol, drugs, or firearms here. I do believe in education for all of those things. I also know that there are always the ones that get or do these things anyway. Maybe this is where the Japan method comes in? In the past in this nation more homes have guns, and more homes had both parents, and maybe a strong family bond, and parents that enforced social norms helped? I don't know the answer and decades of change would be required and still not provide true proof.

Why is it that a conversation cannot be held without a person who doesn't like Trump, bringing him up? He really isn't the biggest problem this nation has. He certainly isn't the solution, but isn't the biggest problem. I don't like him either, but lets dispense with using Trump is a racist as a defense for a point of view.

I live in a country that has a group of people who have decided that they are accepting and tolerant of everyone unless you own guns, have conservative values, attend church and believe in Christian values. This hypocrisy is why there is so much division and hatred. I can't speak for other nations.

Ridiculous comments about guns, as usual from most 'leftpondians'.

In countries where it is very, very difficult to get hold of guns, there are virtually no mass shootings.

I see Fox News etc, and by etc I mean right wing media, are blaming video games for this last weekends 2 mass shootings.

Japan is a culture with a deeper video game habit than the US, but there are no mass shootings. Reason? Two-fold, it is not video games doing it, and, more importantly, guns are very rare in Japan.

If you make it easier for a teenager to buy an assault rifle than it is to buy a six pack, you will get mass shootings.

Especially when you have a white supremecist as a president.

And don't give me that shit about needing an AK47 fitted with a 100 round mag to keep the racoons away from your bins

What a pleasure to hear this show and to know I had some small part in inspiring you to do it! That's tremendous. I haven't ridden my recumbent in about a year mainly because when we moved to the new house I didn't have room for it. It is still at my old house in the storage shed, but we've recently cleared out some space in the garage and I'm going to bring it over and start riding it to work again. It still rides great and still elicits many comments from all who see it. Best of luck with yours, mine was definitely the most satisfying project I've ever done.

BTW my daily ride now is the 1985 Schwinn World Tour I was working on in HPR episode 2154. I love this bike too!

The last comment was referring to the first 1hr of the episode.

Chalk me up for the opposite on just about all the views expressed in this episode. Just in case someone puts together a debate :)

Good to hear the discussion but I sure do disagree with so much of what was said.

Here's to your right to say it!

Thank you tutoro; that bit of bad piping is a melody I learned after NYBill asked me for some audio to represent time passing. It is very few notes, but I always mess it up. :)

It should be noted that no songs were ever written for bagpipes. Songs are compositions that are to be sung by a voice, not played on an instrument. :)

I'm guessing that song wasn't written for the bagpipe.

Thank you tuturto, Hipstre and norrist for your comments!

We had a lot of fun putting the series together. I certainly found out more about awk than I knew before, and I think the same sentiment was expressed by my collaborator b-yeezi.

There's nothing quite like telling others about a thing to make you understand it better. ;-)

Hilarious and informative episode at the same time. Thanks for recording it!

I still want to work on this but this is what I have so far:


https://rmccurdy.com/scripts/PupProxyCheck/

I want to convert my bash scripts in https://rmccurdy.com/scripts/proxy to puppeteer

This series will stand out as one of the highlights of HPR. Thank you b-yeezi and Dave Morriss.

Thank you for the series, you guys! It was great. I learned more than I wanted to. I tried hard to not learn, but you made me. Not just about awk, but about programming, information theory, and data structures, history, bash, etc...

Thank you for the series and the wrap-up episode. It's been a pleasure to follow to series and learn about awk. I don't use awk by myself, but it's always good to know that there are plenty of tools to choose from when there's specific need.

I guess you never know when someone is going to do something unexpected yet awesome. I loved this show.

Hi Jeroen,

What do you do when cars are parked over the hydrants ?

Ken.

Hello! I notice you have recommended FossGeek, and I would like to listen myself but have been unable to find a copy of the files... does anyone have a copy on an old hard disk I can have?

Thank you!

Thanks to you both for the feedback, Bob I figured you didn't expect a full run down of all the languages, but a quick few seconds to mention that languages other than English are listed or not is useful in a review.

Likewise Mike, I appreciate your needs and a quick note to say if the distro is friendly to those with a sight impairment would assist many in the community.

Actually re visiting the last episode and PCLinuxOS I was not able to work out how I could enable a voice assisted install for this OS and likewise on a couple of others I tried in a VM, so mentioning this at the start of the review wouldn't take long.

Regards Tony

I understand that not every aspect of Linux distro review can be covered. But accessibility is pretty fundamental, and all the time podcasts and developers ignore it, it will never get any better.

As I suggested, the podcast I heard was 39 minutes long, and reviewed 2 distros. So that is approx 19 minutes for each. If 30 seconds out of those 19 minutes just answered my single question, can I install it alone, or is there an SSH server running when any Live DVD or CD is booted, then I will be able to either immediately dismiss the distro, or give it more attention.

Some distros are fundamentally bad. For example Regolith Linux uses the i3 window manager, which is a dead loss for accessibility.

Some distros are a disgrace, like the interview Ken gave with the lead developer of Mint a couple of years ago when the dev declared "we're not interested in accessibility."

But just take thirty seconds or so to answer a11y fundamentals.

It is very annoying when so many distros are Debian or Ubuntu derivatives, but have stripped out the speech from the installer

Hi Tony,

I wasn't serious about trying all the languages. I was trying to highlight to Mike that it is impossible to cover every aspect of a distro and all you can cover is your own area of expertise.

Bob

Mike, you make a very valid point and we will bare accessibility issues in mind for future episodes, unfortunately not in time for this month as we had recorded on the Wednesday before HPR aired our first episode.

While I have not had much experience in installing using voice guided installer it is worth looking at for any new reviews in the future.

Bob, as Mike says most modern distributions have very good support for other languages and in Episode 3 when talking about PCLinuxOS I mention the fact that the community forums have an international section which has a number of the most common languages covered, although I did not mention the number of languages supported at install, again worth the few seconds it would take to mention this at the install stage of the review.

It is this kind of feedback that is valuable, as a new podcast we are still in our infancy and learning what the community would find useful in this kind of show.

Thanks again for the Feedback

Tony Hughes
Distrohoppers Digest

I don't think stuff about non-English character sets is very relevant here, since internationalization is part of the standard Linux base and available in all distros. Perhaps whether language can be selected at install time is relevant, but since Tony, I think, mentioned that UK is Ukraine and not GB, or was that another podcast, these installers are both likely to include localization.

I can't commit to joining anybody for a podcast, but I could offer a goodly amount of guidance as to what we, meaning blind people, need to know.

Of course VI is just one aspect of accessibility. Consider also people with limited or impaired fine motor control, or missing hands etc.

At the very least, I want to know one thing immediately with every distro...can I install it alone, IOW with no help from a light-slave. If the answer is no, not interested.

Windows 10 can now be installed by me, thanks to Narrator now being an excellent screen reader. But then accessibility on Windows leaves Linux dead. Just one of the ways in which Windows, IOS, and Mac OS are all superior

I also listened to the podcast and not once did they mention the distro support for non Latin character sets ? Given the amount of people outside the English speaking world, surely they could have took some time to check Chinese support, and Arabic, and Russian, and Greek, etc. !

They made no bones about the fact that they are reviewing the distros from their point of view only. Moss mentions using some proprietary office suite that I'm sure the majority of HPR listeners are not using.

But are these gentlemen even the best people to include accessibility in their reviews? I don't think either of them have a need of, or have any experience using accessibility tools. Would we even be able to trust their assessment given that their inability to use them could simply be down to not knowing which key to use to enable support. Would they even know to check that the speech synthesizer is legible when sped up ?

I would suggest that would be better done by someone who "will not accept any Linux distro which I cannot install alone."

So why don't you contact the lads and ask them if they would be interested in having you join the show to review a distro entirely from an accessibility point of view.

If they are not I'm sure that there would be an audience here on HPR that would love to hear it.

Another Linux distro reviewing podcast in which the word accessibility was uttered exactly zero times.

Two distros reviewed, Linux Mint Debian Edition and Solus, if that is how it is spelt.

This podcast was 39 minutes (approx) in length, so assuming each distro had an equal share of time, then how much impact would be made by spending thirty seconds for each talking about accessibility?

I want to know 2 things always:

1. Is the installer accessible, whcih means can a blind person like me, not visually impaired, BLIND, install it without sighted help. Is there a hot key which starts the Orca GUI screen reader, or speakup if it is a text-based installer.

2. If I chose speech for the install, assuming number 1 is true, then when I reboot will it come up speaking.

Note that I will not accept any Linux distro which I cannot install alone. None of you would entertain any distro for which you had to run to a blind person for help installing.

Please, spend some time adding accessibility to your headings, otherwise this podcast is worse than useless to me and people like me

I like the episodes where the host wanders through a few short topics. It reminds be of the old Dave Yates Lottalinuxlinks podcasts.

I really enjoyed this interview. Impostor syndrome is something I think we all deal with at some time or other, and he had good things ot say on the subject. Please keep interviewing interesting people like this.

Welcome aboard, man. Part of the crew now. ;)

I had tried NagiosPi and came to the same conclusion as Robbie. This looks like it will be a great alternative. I will definitely be contributing and recommending this software. Thanks to Robbie for the great project and to Yannick for the fantastic episode.

Hi folky,

Thanks for the correction. I have made the change to the notes.

Dave

The command in the shownotes is missing a %-sign. It should end with %S%Z_%A

Who would have thought that plumble should give my voice in such a good quality - not to forget over 4G in a train going more than 180 km/h if I remember right. Next time I should record a show live on my Nexus 6 over plumble in the train instead of my room with the fan right above my head ;-)

In answer to '1)' we don't know the nature, nor should we. This is HPR and any host can post whatever they wish without us checking it. If they don't tell us it contains copyrighted material we would never know.
2) I don't know but I do know I don't want to find out.

I would have commented on the Community News show but couldn't make it due to my audio being messed up!

I really appreciated this episode because it made me realise I was a bit unclear about the issues.

The first language I learnt was Algol 60 (around 1970), and later used Pascal a lot. The Algol course was as a Biology undergraduate where they were trying to make us appreciate how we could use computers in our subject. (This was way before Bioinformatics, so we were mainly writing statistical stuff and learning how to plot results).

Anyway, these languages exposed me to lexical scoping, as you mentioned, and I guess I haven't really reflected on the nuances of dynamic scoping since then.

So, thanks for the eye-opener ;-)

Ken makes a key point when he says “While the host may be correct, if they are not, then it is me and not the host that will be held responsible for posting it. I do not want that responsibility.”

My two questions are, 1) What exactly is the nature of the two remaining clips whose inclusion is problematic? and 2) what would “being held responsible” mean in practical terms?

On the first point, how long are the clips and what are they of? Music? Broadcast footage? Do the clips comprise the entire original work or do they amount to a minor quotation?

In the US, Fair Use is an actual legal limitation of creators' rights under copyright law. The US also has the DMCA, which effectively allows providers to host anything, and if a copyright holder has a problem with their stuff being included somewhere they can file a takedown notice and the provider handles it by simply removing the content in question. But this is not the case in other countries, particularly the EU where there has been a lot of, shall we say, new development in this area recently.

If the answer to (1) is "the two clips are actually entire Beatles songs"…then there isn’t really a legal defense no matter what jurisdiction we're talking about.

But even if the answer to (1) is "They are fifteen-second excerpts from an hour-long lecture given at a public university", …If the answer to (2) is "we don't/can't know so we are acting out of an abundance of caution" I can respect that.

Sorry to hear that the event got cancelled, it sounded really exciting. When you in the beginning were talking about capture the flag, I was under impression that it would be the kid's game, where you're trying to steal flag from opposing team. Only after you started talking about lockpicks and hacking it dawned to me what kind of capture the flag you're talking about here. Super interesting episode, I hope you can eventually make one about actual event (different one than cancelled of course).

Sadly, this event was cancelled before the show aired. There was serious flooding in the area. Luckily everybody is safe.

This was the most informative "origin story" story of a distribution I've ever heard. The little details (like building the initial distro in droplets on Digital Ocean, based on a $10 voucher) are fascinating, and provide real insight into how some of these cool "little" projects actually happen. Thank you for this, Yannick-the-French-guy-from-Switzerland!

Can someone please step forward and do a video of this with this show as the audio track.

This link has also been recommended by a colleague https://learngitbranching.js.org/

Pretty good episode on the speculative execution stuff that Intel and others are dealing with. And don't feel alone, I also run OpenBSD as of late! Been dabbling with the BSDs since 3 years ago and, of all of them, OpenBSD is closest to my heart. I'm running OpenBSD-current on an old Toshiba Portege M400 convertible tablet PC as well as on a ThinkPad x230 at work. Yeah, certain things like wireless aren't up to par yet as they are on Linux or even FreeBSD (which I also run on a laptop at work), but it is a great OS with great security and support. Another HPR contributor by the name of Sigflup also runs OpenBSD, and to be honest, her use of it was what piqued my curiosity to the OS. So, rest assured, you're in good company as an OpenBSD user on HPR. ;-)

The Linux desktop gives up and coming sysadmins a playground to learn Linux - which they will need to know for server administration.

Love this cast and your own personal podcast off this network!

That being said, I wanted to say something again that I said in one of my podcasts, and that is that the desktop is dead. Not dead in the sense of no longer being developed, but the whole concept of the desktop is outmoded. For most people, they're day-to-day is their personal tablet and/or smartphone. I know many people who no longer would want a desktop or laptop. For me, my companies computer techs have such a bad system setup that most of the rank and file will use any phone app they can get on they're hands on in order to avoid using the shard desktop machines our company provides.

I love my personal desktop environment, and the lack of customization for windows and mac keeps me on linux. Every time I consider going back to windows I eventually end up wistfully checking the status of things like BB4Win and searching for alternative gui shells. If you care about your personal computing environment, you need linux. It's like this, in America a car enthusiast would probably want to be in California because California has a "car culture." If you want your environment to respond to what you think it should be for you, you have to do linux.

Knightwise, I respect your knownledge in computers. But I disagree on one point. You said something like, when you need to get things done, only windows and Mac can do it. Maybe so for you, butI can do many things in Linux at least for my needs. I've been using Linux for 21 years.

Thanks for the feedback and the podcast recommendation! I’ll definitely be adding it to my queue.

There is a lot to agree on here. Thank you for the podcast! I certainly agree that the distro-obsessiveness is absurd, and there should be more of a focus on applications. And there is so much overlap and duplicated effort in every area of software in the Open Source world.

I tend to think that Microsoft's recent dalliance with "openness" is just a case of Embrace, Extend, Exterminate. Essentially, an attempt to get Computer Science students and Programmers to think of the Command Line, and Linux as an esoteric extension of Windows. But who knows what they are thinking.

Hi Knightwise. While for the most part I agree with your arguments about using cross platform applications, I think the title of this comment is as valid as the title of your episode : I can run Audacity on my linux desktop, I can run firefox and freemind and Visual Studio Code. So, my question is, should we dump Windows ?
And the answer is obviously "no", because both our questions are flawed. Should __I__ dump Windows ? Should __you__ dump linux desktop ? Now those are valid questions. I have personally made the choice to ban Windows from my house, because I can do everything __I__ need on a linux desktop. You said that you can't write documents or make presentation on Linux and that is a perfectly valid reason for __you__ to dump the linux desktop. But as a general rule, no, __we__ should not dump any desktop, be it macOS, Windows, Linux, or any of the exotic ones. As you said in this episode, it's all about choice.

Also, you mentioned OpenOffice in this episode. I really hope you meant LibreOffice. Because OpenOffice... well... need I say more ? By the way, LibreOffice runs on windows, mac, linux and android. Another great example of cross platform software.

Anyway, thanks for sharing your thoughts, and even though I don't agree with all of them, I appreciated your point of view.

This was a great episode. Lots of listeners including myself are interested in the legal aspects of hacking. Thanks for the deep dive.

One of my _other_ favorite podcasts is related to this episode - http://faif.us/

I am aware of the conference, but frankly I haven't seen anything in the schedule that would draw me there. It's a mix of corporate promotion, blockchain and random student projects ... nothing about languages or development frameworks or services, which is what interests me the most. I don't feel a free software pulse there, no work toward building a Hong Kong free software community.

Hi clacke,

Yes, thanks for the link. I thought "I put that link in my notes", went and looked and found I'd messed it up, so I just fixed it :-)

The show is number 15 in the series and is now on the site as https://hackerpublicradio.org/eps.php?id=2824

I heard your comment again on the Community News and discovered that you were talking about awk coprocesses also, not just backticks. :-)

I didn't know about them! Looking forward to the episode.

For anyone wanting to read ahead of the class, the documentation page is here:

https://www.gnu.org/software/gawk/manual/html_node/Two_002dway-I_002fO.html

I didn't mention Hugo Weaving because a superhero movie is a credible source for accuracy, but for reference because he happened to be accurate. :-)

This is the kind of episode I'd love to have played on NPR or some de facto talk radio station. On the one hand, it's "preaching to the choir" here on HPR, but then again, the topic is actually bigger than just podcasting. Where have all the blogs gone? the little indie websites and fansites? The Internet in general is a lot more cookie-cutter now than I think it was ever meant to be. As Dave Morriss says in an earlier comment, it's up to us to keep grassroots alive.

Yes, that's why the dollar-paren was introduced. Backquotes can be nested too, but that requires escaping them with backslashes and we don't want to go there if we can avoid it.

Apart from the nesting thing, I find dollar-paren easier to read, especially when enclosed in double-quotes, as it usually is.

I thought that one difference between the two is that dollar-paren trims any trailing newlines, but it turns out I was wrong -- they both do that, so the difference is purely about quoting and readability.

This is a great rant, Knightwise, but you don't spend any time talking about what Adam has been up to lately, which is EXACTLY the kind of podcast you are encouraging all of us to create and explore. From your handle, I assumed you were also a Knight of the No Agenda Roundtable, but you failed to even mention Adam's twice a week podcast done with the cranky geek himself John C. Dvorak. You need to hit more people in the mouth about the No Agenda Show (http://dvorak.org/na) Noagendashow.com

Consider yourself clobbered, dude!

Hi Knightwise,

Interesting show. I started listening to podcasts in 2005 or thereabouts. I'd just bought our first family PC (Windows, yuk!), signed up to my first ISP, and had started looking for stuff to listen to. I bought my first MP3 player that year, an iRiver iFP-899, and was using Juice or similar as my podcatcher.

Yes, I listened to the Daily Sourcecode and to Dave Winer (originator of RSS). Some great times!

I also remember Pirate Radio from the 1960's. I was at school in Norfolk, in the east of England, and we all listened to Radio Caroline (https://en.wikipedia.org/wiki/Radio_Caroline) and Radio London (https://en.wikipedia.org/wiki/Wonderful_Radio_London) from ships off the east coast. I'd listen to Veronica at times, but not a lot since it was in Dutch and the signal wasn't as good as I recall. Also good times though!

Thanks for the memories ;-)

Though I hate the Capitol Onr commercials, they have something new and notable. Their ENO product is a credit card that gives you a new credit card reference number for each vendor you buy from, so if your credit gets stolen, you only lose the one reference number, and all the other bills you pay with your credit card are unaffected. On top of that, you know which vendor compromised your credit card.

you have the cable and case, but you need a USB-C hub / dock to connect your old usb stuff, you can get them at various websites:
https://www.usb-c-adapters.nl

Now that mandatory pirate speak has been done, I can comment. There's market for both kinds of podcasts, grassroots ones and more slick and commercial ones. Latter ones won't disappear as long as there's money to be made, so it's our task to keep the more grassroots style alive.

Thanks clacke, I enjoyed this a lot. Nice to be on the receiving end of the Bash info for a change ;-)

Command substitution:
It's my understanding that the newer $() form is an improvement on the older `` form largely because the substitutions can be nested. At least, when I found it years ago I was excited to be able to nest them! I assume it's nestable because the new form is easier to parse.

coproc:
This seems cool, though a little involved. I'd looked briefly but hadn't really thought about the feature. Thanks for covering it.

Since b-yeezi and I have awoken the Awk series from its hibernation recently, I'm going to cover redirection and Awk's coprocess feature as well. Episode 15 is almost ready to be recorded and uploaded.

Dave, sorry it took me so long to respond to your very thoughtful comment. I appreciate the link to the self-playing instruments video podcast. There are some really good ones in there. I'm especially impressed by the Self Playing Steinway Duo-Art Piano - recorded by Sergei Prokofiev. That one is nearly as faithful to the actual playback as the Yamaha Disklavier, but is limited by the length of the paper that is recorded on. It's an analog equivalent, incredibly accurate in its reproduction. There were earlier ones, too. That whole phenomenon would merit an entire series but I don't know that much about it haha!

Hi Windigo, thanks for the comment. Yes, I did work at the Library of Congress in the summer of 1993 as a "Junior Fellow," a paid internship that was quite prestigious. I don't know if they still have this or not. It was an amazing gig for a musicology nerd to get to work in the Music Division helping to process the recently acquired archives of Aaron Copland. Maybe this *is* worth an episode of its own!

First of all, this has been one of my favorite shows of all time. What a fascinating musical instrument, not to mention a cool piece of technology!

But then you drop this in nonchalantly:

"I was working at the Library of Congress in Washington, DC, one Summer..."

Dude, it's possible that you've covered this elsewhere, but I'd listen to a whole show about how that happened. It's always great to hear from you!

I love listening to this series and started wondering, how applicable and/or easy would it to adapt these topics in non-fictional story that isn't a story at all? If there's a book that teaches readers about programming, can some of these topics be still relevant? Could a study book build towards some climatic revelation that is hinted more and more as it comes closer and then revealed in all its glory?

Great start for the series! I love learning how people are learning new skills like programming languages.

Glad you found it useful. While you can use it alone, it's also useful with tools like PsExec from the Sysinternals suite. I might do an episode about that particular command as well. That suite has so many tools but PsExec is the one I use the most.

https://docs.microsoft.com/en-us/sysinternals/

You could probably create a batch file or Powershell script to go through a list of hostnames and have them reboot/shutdown remotely.

Whoops I thought I said hundreds or thousands, not hundreds *of* thousands. ^_^

You said you could listen over the internet no mater how many 100s of thousands of miles away you are. What moon/planet would that be? :)

Sorry, I could not resist.

It was an interesting show, thanks.

Hi Jon,

I loved this! It's a magnificent instrument. I never knew there was anything quite so sophisticated.

I watched the 'Music Machine Mondays' on the Wintergarten Youtube channel a couple of years ago. They visited the Speelklok Museum in Utrecht and looked at the marvels there (playlist at https://www.youtube.com/playlist?list=PLLLYkE3G1HEBO1slIc1RRfcfSsGyv2oMu) but this Disklavier is a significant evolution of these machines.

Listening to your show I was reminded of a thing I liked to listen to when I was a kid: 'Sparky's Magic Piano' (https://en.wikipedia.org/wiki/Sparky%27s_Magic_Piano). It was often on the radio on Saturdays on a children's music programme. This was probably in the 1950's.

I was slightly puzzled by the pronunciation of "Disklavier", thinking it should be pronounced the French way. A bit of Googling proved me wrong - and you right of course! In my defence I used to live in an area of rural England with many villages named after Norman French families which were pronounced strangely (to my ears). My favourite was Little Hautbois, an easy cycle ride away, called by the locals 'Hobbis'! (https://en.wikipedia.org/wiki/Little_Hautbois)

I’m not by far music “literate” but the technology in this is so mesmerezing. I’m wondering it the tech exists for other types of instruments, i.e. wind, percussion.

But remember, in 1722 Bach wrote Das Wohltemperierte Klavier, and at the time the "piano" as an instrument did not exist. It had to mean either keyboard or harphsichord or clavichord. Keyboard is most generic.

Thanks for the insight. There's a scheduled power outage at work next month, and with this I can make sure everybody's workstation is shut down properly without running around and looking at power lights.

Hello folks,

Diskette is the German word for floppy disk.

Klavier is the German word for piano.

Tastatur is the German word for keyboard (at least in terms of computers).

A pianos keyboard would be called Klaviatur.

So Disklavier can be split into Diskette and Klavier.


Thanks for the fine show :-)

Music to ears, literally. That disklavier must be really high tech as it can replicate playing so well. And watching the video of disklavier playing was really nice bonus. This reminded me of time when as a wee lad I made a trip to museum of mechanical music and they had completely mechanical piano that could play different dynamics, flourishes and what not.

Take it from someone who records shows on their mobile phone: Your audio quality is great. :-)

More on what local variables are and how they work in episode http://hackerpublicradio.org/eps.php?id=2807 .

As a Scandinavian, I can say that your pronunciation of Yggdrasil is entirely accurate, and if anyone doubts it, they can hear Hugo Weaving pronounce it in much the same way in "Captain America: The First Avenger", which by coincidence I saw only a few days later.

Thanks for the podcast. I learned a lot. These protocols are fascinating, because to the end user, a few bytes here or there seem to be insignificant. But across the entire network, a few bytes here or there can add up to millions of dollars.

Oh, and the audio is great.

Thank you for the comments and episode idea. Haskell certainly is drastically different language compared to many others and learning curve can be steep. Sometimes it feels like I'm reading a math paper when I want to check for some feature or learn a new thing.

I'll make a note and record an episode "Why Haskell" at somepoint in close future. There's quite many Haskell episodes in the queue and I don't want Hacker Public Radio turn to Haskell Public Radio, so it might take a month or two.

Hi Knightwise

Whenever we are in the market for a new computer I think we inevitably want to get as close to the latest technology as our budget will afford. However, I think that can lead to a subconscious over-specification of our requirements as a way of justifying the purchase.

A few years ago I had selected a very nice Sony laptop that I convinced myself was exactly what I needed to support my work. Unfortunately an unforeseen breakdown of my car meant I had to spend roughly half of my budget to get it fixed and back on the road.

I still needed a new laptop but the Sony was now out of the question. I revisited my requirements and realised that many of my "must haves" were really "would like to haves". If it took a minute or two longer to rip a DVD did it really matter? If it took an extra few seconds to open a very large image-laden document was that really the end of the world?

By adopting this approach I found I was able to purchase a Dell rather than a Sony with what was left of my budget and its few relative shortcomings were almost immediately forgotten.

I've been writing software for over 30 years but I find the syntax of Haskell anything but intuitive - in fact less so than any other programming language I have looked at. Thanks to your excellent show notes I can make sense of it but I have to say I would not like to have to develop a project using this language.

Obviously I am missing the point as nobody would design a language with the intention of its being difficult to use. Perhaps you could produce another episode addressing the question "Why Haskell?"

An excellent episode for all that.....Thanks.

long time listener almost first time comment.

I wanted to say I've always enjoyed your podcast. I don't read books or play d&d but I do watch a fair amount of TV and movies.

You can hear the amount of passion and what you're explaining and I personally feel almost smarter when I can go back and understand why a story I remember was great or horrible!

Interesting. I am right now learning how to use Wireguard for end-to-end encryption. Wondering how it works in IPv6. Different approach but similar goal.

I have not used Gentoo on well over 10 years. Could you do a show about why you are using Gentoo and how it compares to debian/ubuntu/fedora/...?

You expressed some concern about your microphone, but there was no problem with your audio. Loud and Clear.

Great show. I hope you do more podcasts on any of the topics you mentioned in the show. Don't hesitate to give detail!

I hadn't ever heard of CJDNS or Yggdrasil before, so I learned more today (and I'm not even done with morning coffee). I would love to hear more on what one could do with mesh networks (broad topic, I know).

Nice job, man. I never knew about the different charging levels for different types of vehicle batteries. I always just bought one that fit, and threw it in.

I'll be more careful next time.

This is sure to come handy. We're driving only short distances with car and while it hasn't yet damaged the battery, I suspect it will eventually do that. I'll have a look at the type of the battery and see if smart charger would be a good idea. Thanks for the information, I wouldn't have learned this otherwise I think.

Thanks Klaatu, this really made my week. I try to work on the game at least a little bit every day, but sometimes progress feels super-slow. I do like building mechanisms that mimic places and their inhabitants and hopefully eventually allow emergent stories to pop up. Until that day, it's slow work of adding one more cog to the machinery.

This is just so cool. The worldbuilding part makes me want to write a script to generate random solar systems with unique planets and constellations.

I love this project, keep going!

klaatu, remember that inertia is the most powerful force in the universe.

I guess I could have looked up fdisk. Thanks for overlooking my laziness.

Very enlightening about the C drive! I can respect extreme backward-compatibility, so I don't mind that they don't reclaim A or B. That said, the scheme is pretty stupid. I'm surprised it stuck around, but I guess once they'd made the decision, they just figured it was too late to change. It seems the more I learn about the historical Microsoft, the more I feel like it was started with no prior research, but then again maybe I'm biased because we live in such an open source world. After all, maybe back in the early 80s you couldn't just call up Bell Labs and ask if the way you're programming disk detection made sense or not.

Klaatu mentioned he wasn’t sure what the ‘f’ in ‘fdisk’ stood for. I had always been positive it stood for “format” because DOS had an fdisk command and that was pretty much its main use. However, I looked it up just now and turns out I was wrong, it stands for Fixed, as in Fixed Disk Setup Program.

He also seemed unsure of the reason why the main hard disk is usually C in Windows machines. PCs would originally boot off the floppy drive, which was always A, and for convenience, a second floppy drive was often added and it was always B. So the hard drives started with C. I don't think there's any technical reason A and B haven’t been reclaimed, but when I read `A:` or `B:` in a path, I still think “floppy disk”. At any rate, the whole scheme is sad and dumb!

There is an open source project called LessPass that is trying to solve the password management problem in much the same way that you are describing. Passwords are generated in a deterministic and algorithmic way using a master password, some known values related to the site, and some cryptography.

There are two challenges that I see with this concept. The first one, that you made reference too, is how do you write an algorithm that will generate a password that will be acceptable to the policies of any site.

The second is, how do you deal with sites that insist that you change your password from time to time? In order to do that, you about have to change your algorithm, which means that all your other passwords will be broken.

If these two problems can be solved, I'd be all for this type of password management.

It's been a while since I set up my email - server with SPF, DKIM and DMARC. Since I'm about to migrate it to another server this has been a valuable reminder of what SPF is about.
I also think it is much clearer than every guide I read at the time I had to set it up.

Well written by deepgeek and well read and extended by Klaatu - Thank you two!

I used this episode to help me understand why some of my email was ending up in people's spam box. I added an SPF record, and now all is well! Thanks.

I'm glad this helped, Steve.

You're not the only one this episode has helped. I've referred back to it at least fortnightly since posting it!

Page 19 has 3 tables (2-1 through 2-3) with a summary of bonus values for race, themes, and class.

I think two lessons learned:

0. use the official character sheet when building a character for the first time
1. actually read

This was way deeper episode than what I expected after listening couple more minutes. Really great, albeit sad at the same time (just like life) show.

Reminds me time when I started role-playing games and how I as a dungeon master couldn't bring myself to actually get players killed, but had to always come up with a some way to save them. Players had fun, but challenge wasn't really there.

NO, NO, NO!

This is likely to be an accessibility nightmare and might well render it impossible for blind participants like me to read the notes at all.

I admit I rarely consult the notes, except for shows with a *strong* hacker twist, like the shows about xsd or Dave's bash series of shows.

Anything which is likely to have links, such as links to github repositories, or fragments of code I might like to copy and paste and fiddle about with.

I can't imagine that other people who refer to show not3es for clicking on links will be helped by embedding text into media files either.

And while on the subject, I have not seen this yet on HPR I think, but when anybody includes the output from cli stuff in show notes, posting screen-shots of console or terminal output also makes it impossible for me to access the text.

Keep the show notes as separate text please and don't embed them into media. If you do, maybe we can have them as both.

Haha Sorry, Bill! Please do the show anyway. I think the foot pedal is actually working fine, it's just that I didn't realize it was switched over to the other channel while I was working on the amp and the foot pedal wasn't actually plugged in at the moment. I realized my mistake when I plugged the foot pedal in and stepped on it and suddenly saturation was working because it was on the right channel.

Thanks for the tip on the cleaner / lubricant. I think I will check with my audio engineering faculty guy and see if he's got a can sitting around that I can blast some into the pots without having to pay twenty bucks for a can myself. :)

Stealing a show I had planned, Jon!

http://media.gunmonkeynet.net/u/nybill/m/winter-to-do-list-fix-this/

All right, all right. You beat me to it fair and square.

BTW, there is contact cleaner that is specifically made for music gear and it does contain a lubricant. Its made by DeoxIT and the line of products is called Fader (Their font choice on 'Fader" looks awful familiar!

Also, I would say your saturation is not working properly, if at all. That thing should give you all the Hair Metal distortion you could ask for. :P

You might have a problem with the foot pedal. I had this same issue in the past. You might be stuck in NORM GAIN. And the pedal is not switching into LEAD GAIN (where the Saturation is).
The problem I used to have is, the 90 degree jack for the foot pedal does not retain/grip the cable in any way. Any tug on the cable can break a solder joint inside. Its something to check out. Its only a couple screws.

Good luck! And get some hair spray!

Hi Jeroen,

thank you for your talk about AS/400 systems . I was working with those magical machines for about a decade and I must admit it was truely enjoyable experience. Thanks again for bringing back good memories. Cheers. treboR

P.S. I don't know how about others but for me those machines will always be AS/400 no matter what new marketing name IBM would invent for them iSeries, System i, etc... ;-)

Great episode. The question is how to get the target audience (the people who'd be fooled by this kind of transaction) to listen to this. I think part of the problem is that people who are fooled by this sort of thing have no interest in learning about it.

Then again, maybe people-who-can't-be-bothered aren't the audience.

Either way, thanks for the walkthrough of the investigation. It's great to hear an example of methodical analysis.

Alison, I've been pleasantly surprised here in Hong Kong that if I ask the store clerks, they will generously allow me to boot from my USB stick to see how well Linux runs, no complaints whatsoever.

And that's lucky too, because last spring and summer when I was shopping for a new machine, I tried like ten of them before I found one where screen, Wi-Fi and touchpad were working without glitches and the machine didn't crash after a few minutes.

Just wanted to say thank you for this episode. I needed to reduce the size of a PDF today, and I knew right where to come and the necessary command was in the show notes. Worked perfectly.

Thanks for the comments, VulcanRidr, very glad to hear you enjoyed the episode. I've seen the RT-909 that you mentioned in catalogs and on eBay, and that would be a great tape deck to have. Takes considerably more space than the 707 and probably would not fit in my stereo rack because it would need room above it for those big reels to spin. I'd love to have one, though! I believe the YouTube Techmoan host has an RT-909 in his collection. If you do pull it out of storage and set it up, I hope you will do a response episode about it. I would love to hear that.

I listen to hpr on my android phone using antennapod (available at f-droid) and can see the shownotes and the links in the show notes take you to the website. Great application!

I listened to your RT707 podcast this morning on my way in to work. What a blast from the past...I have the RT909 (https://i.ebayimg.com/images/g/uPsAAOSworNcRKPc/s-l300.jpg), the 10" reel version of the same tape deck that you have. I picked mine up in the mid-to-late 80s. Now I am racking my brain to figure out where I can pull it out of storage and set up. I want to go back and listen what I put on some of my tapes...

Comparing traditional music formats, LPs, reel tapes, etc to mp3s and oggs is like comparing "dead tree" books to e-books. With books, you have the physical sensation of a paper book...The smell of the book, the feel of flipping pages. Meanwhile, with music, not only do you have the spinning tape reels and the movement of the tonearm, but more than that, analog music has more depth and richness, and is generally a warmer ambience than digital music. But at the same time, I can put several hundred thousand digital tracks onto a device which fits in my shirt pocket, and only need a pair of headphones to partake.

Anyway, it is gems like this show that make me enjoy HPR. Thanks Jon!

This was really fun episode to listen to and it made me kind of want to play some roleplaying game again. The comment about charisma being least useful stat made me think how it depends on the game being played and the group. Some like shooting (or hitting, or magic missiling) everything that moves, while others like politics and intrigue. Probably best to have a chat before game to set expectations what kind of game people are generally looking forward to.

thanks for a wonderful episode

Wow, Dave, I REALLY wish you still had that Clarion tape machine! I love stuff like that. A portable reel-to-reel tape deck is definitely on my wishlist of vintage audio. Incidentally the YouTuber Techmoan did an amazing episode about the tape decks of Mission Impossible, featuring the Craig 212. Thanks for the feedback. :)

Thanks Jon. This was a wonderful voyage of nostalgia.

As a teenager I had a portable Clarion tape deck (https://www.radiomuseum.org/r/gbc_clarion.html?language_id=2) which I'd bought from my cousin. It got a lot of use and I learnt how to splice tape and make tape loops back then. I'd record the latest hit records off the radio to share with friends and family. I did some basic repairs on the player, and learnt to solder when the leads and plugs needed fixing. The Clarion died eventually and probably got junked sadly.

I always wanted - but never acquired - a big reel-to-reel player like a Grundig, Philips, TEAC, or whatever. Great to hear about your adventures in this area!

Thanks for your comment, Bookewyrmm. It's too bad about your Edison disc. If you enjoyed this episode about open reel tape, then you might enjoy one I did a few years ago about my Victrola in episode 1339.

Incidentally I recently discovered a guy on YouTube who does amazing videos about Legacy audio formats, a user called Techmoan. These are just awesome. I highly recommend subscribing.

I just finished listening to the episode, and wow! I love finding and listening to older media. The "Crown Jewel" in my collection is an Edison Record. Sadly it came to me broken, but I do have all of the pieces and the cardboard storage cylinder is whole, so even if I do ever find a player, I couldn't play it.

For those interested, here's a link to info on Edison Cylinder records

http://cylinders.library.ucsb.edu/history-goldmoulded.php

Follow-up: research on the issue indicated that a non-functional tape counter in this machine was about 99% likely to be from a broken belt. The reels are direct-drive but a belt turns the counter. I got a replacement belt from eBay and installed it today, and I'm happy to report that it works perfectly now.

I spent probably most of the first half of the eighties playing Elite on the BBC micro. Or Donkey Kong, or writing code for it.

Last time I used one, or was it two, was to calculate the position of the Moon and steer a huge VHF antenna array to point at it, late eighties and early nineties. Wasn't ideal since the ADC port was only 11 bit, so no great accuracy with the Moon's position, could not have pointed Jodrell Bank with sufficient definition.

I could see back then.

I am very jealous of all of those classic 8-bit classic games at your fingertips. And all loading fast.

You must have been sick when the PSU blew up.

Last question...where can I find a wife like that?

Thanks for this wonderful episode. The bbc seems like pretty cool machine. more episodes on this please!

Cool, thanks for sharing! Very interesting episode.

Good episode!

Thanks for the show Andrew.
My first contact with any computer was the BBC in the "Big" class (Final year) at primary school. I can vividly remember playing Granny's Garden [1] when I was 9 or 10.
Then at secondary school while everyone was messing around with the new windows 3.1 i386 machines I spent _days_ on the only BBC left in the school typing code in from a magazine called quest [2]. The code was some sort of database programme but it never ever worked and so far above my skill set to debug it just sat on my 5 1/4" floppy destined to stay in my school bag until the end of time.
I actually gasped and swore when you jogged, well set a nuclear bomb off in my memory with the two words "Star dot". I had forgotten how simple the commands were.
Anyway please please do a follow up show. I would love to hear more about the BBC and see how much I can remember.

[1]https://en.wikipedia.org/wiki/Granny%27s_Garden
[2]https://en.wikipedia.org/wiki/Quest_(British_magazine)

I LOVED this episode! I like anything about retro equipment, making old stuff work again, using legacy equipment/formats. This was great. My own interest is mainly audio, but it's great hearing about any of these old tech products that are still usable or are being refurbished and loved again. Thanks. :)

Great episode. I'm jealous. So much nostalgia.

I actually bought a BBC Micro in about 1981(?) having previously owned an Acorn Atom (I think). What's more I still have the Beeb, though it's mouldered away many years in the attic. I bought the Z80 co-processor, the "Prestel adaptor" (modem in a beige box), a dual floppy disk drive and a bunch of other stuff including the RGB monitor. It was my main computer for many years.

It's been something I have been meaning to do for some time - resurrect these devices. The replacement of all the dead electrolytic capacitors might be more than I can manage, but I'll have a go. If not then I know I can buy a properly refurbished one off eBay ;-)

I hope you'll do more shows about your experiences with this magnificent machine.

I never actually owned BBC, but read about them a lot when I was kid. Especially Elite was touted as the best space game ever and BBC version being superior in every possible way. Thanks for making the episode, it sure resurrected bunch of old memories.

Hi Klaatu, I took some advice from our friend Dave Morris he suggested I might like to use the RSS feed to keep track of comments. I got hold of a simple RSS feeder on the Android play store. It seems to be working out great as I was alerted to your comment. Without the reader, months may have gone by before stumbling across your comments. Mashpodder is ripe for modifying especially since it's so well written with loads of good comments. I have plenty of unfinished projects so I can relate to what you are saying.

All the best
MrX

I've resumed using mashpodder for podcatching just recently.

The audio jack on my mobile failed (rending my mobile functionally useless as a podcast listening device), so I dug out an old media player loaded with RockBox, and I use it as my listening device. For one day, I tried loading it manually with podcasts, and then realised that I needed something to manage show downloads for me, and mashpodder is what I turned to.

I started modifying it so that it would run an arbitrary script (such as a conversion script) but got distracted. Maybe later....

Hi LnB,

Loved this show as ever. It got me thinking that I enjoyed "The Usual Suspects", and "Fight Club" as two well executed movies. Both had me going back to watch it again to see how they fooled me.

I would like to argue that "The Sixth Sense" took the premise of the unreliable narrator(s) and did something unique to set it apart from the other two. Namely they produced two entirely different films from the same series of pictures.

The first time I saw it I watched a Horror Film starring Bruce Willis, and saw a story about a man who discovers the truth.

The second time watching it I saw a Drama starring Haley Joel Osment, and saw a story about a boy struggling to accept he is different, having to deal with difficult situations and learning to trust again.

After listening to your show, I realised that this was only possible because both characters were Unreliable Narrators, one unknowing and the other using it as a tool to help.

Ken.

I'm one of the folks listening through the HPR back catalog (in descending order). Older episodes are often still relevant, and those that are a little "dated" are still fascinating from a historical perspective.

Like Ken mentioned, this is also a fantastic way to flesh out the tags and summaries on older episodes. It only takes a few extra minutes per show!

Thanks Yannick, I really enjoyed listening to this. Very well done.

It was also great to hear Jeroen on the Community News again. For the record the HPR "muggers" at OggCamp 2018 that suggested he join us were JWP and myself ;-)

I caught something a bit like flu just after Christmas - but it can't have been flu because I had my flu shot. Anyway, the notFlu, or its aftermath, is still hanging on three weeks later.

A very informative episode. I hadn't realized how different the shutdown command functions on illumos-based operating systems is from the BSDs and Linux. You've also inspired me to make an HPR episode on a similar command with the same name in another OS I have to use from time to time.

Hi yes indeed wonderful microphone, unfortunately, I've never had the pleasure of using such a mike myself. The picture was actually to show an example of a radio with a moving analogue tuning needle that moves across the front of the radio, the microphone just happened to be in the picture.

The AVO meter is indeed a classic and something I have personally used on numerous occasions many years ago, they look like something out of an old horror film and are very heavy, built to last.

Best wishes MrX

Many thanks for the comment much appreciated
Very sorry for taking so long in replying I'm not very good and checking for new comments probably for the same reason that I didn't include the interesting noise from my tuner. Afraid it all boils down to time or lack of it as I would have had to set things up and make a separate recording and I was just keen to get the show finished my apologies, again the same reason for not giving audio examples of the noise blanker. Also thanks for the information on relays having never owned a modern HF radio I assumed they would be silent, thanks for the clarification

Best wishes MrX

Joel H,
I just read your comment and looked at "The Stanley Parable". I think this would work just fine in a first person exploratory game. As I've thought it about this and games more, I can't think of a game type this wouldn't work in, actually.

First person mode would be interesting in the thoughts could switch from initially being in the native language but switching to the new language as progress is made. That's sort of the ideal situation I suppose in general. If you can think in the new language I suppose you've won.

Yes, I just saw that on Mastodon. Thanks for the heads-up.

Oh boy, lots of fun for me, infinite vistas of tedium for my audience ;-)

http://lists.gnu.org/archive/html/bug-bash/2019-01/msg00063.html

BASH 5,0!!!

Thanks for the comment and offer, Scott. I'm more a coffee drinker, and rarely in Cincinnati any more, but drinking and talking about tech is pretty much my favourite pastime. So if I'm in the area I will absolutely broadcast it on the HPR mailing list so I can take you up on your offer!

This is a very cool feature which I use a lot!

I'd approach your example with a little script, 'pathparse' which shows you don't need 'dirname' or 'basename':

$ cat pathparse
#!/usr/bin/env bash

path="$1"

directory="${path%/*}"
filename="${path##*/}"
prefix="${filename%.*}"
suffix="${filename#*.}"

printf '%-9s: %s
'
'Directory' "$directory"
'Filename' "$filename"
'Prefix' "$prefix"
'Suffix' "$suffix"

$ ./pathparse /etc/apt/sources.list
Directory: /etc/apt
Filename : sources.list
Prefix : sources
Suffix : list

Nobody emailed me revealing that they found the hidden object. To be fair, there wasn't much time, it was around the holidays, and people are busy. I should look at the server logs to see how many people actually downloaded the sample PDF containing the payload.

I believe that most listeners consume HPR from RSS and never see shownotes (and all of my subtle hints that there was more than meets the eye about this mini-series were only in shownotes).

Anyway, it was a fun experiment, and interesting data about both steganography and the PDF format.

Didn't know about Substring manipulation

Also found out why the following works


filepath=$(dirname -- "${source}")
filename=$(basename -- "${source}")
extension="${filename##*.}"
filename="${filename%.*}"

Solid work klatuu, if you're ever in the Cincinnati area, I'd like to buy you a beer and pick your brain - Scott

Great episode. I have already started using this tip in my Tiny Tiny RSS instance.

Thanks for the informative episode! I've bumped up against the AS/400s a few times in my life, but never managed to find out what they were all about.

I feel this was a great intro, and I will be poking around the museum to learn more.

we need to know.

Quilt sounds really neat. I can't wait to try it.

Thanks for a great episode!

https://docbook.rocks/
Is a neat site talking about docbook and how great it is.

This was a fascinating peek behind the scenes. I love hearing how open source musicians produce their music, and I loved the samples of the music at the beginning. Very cool!

I've asked, I've skimmed wikipedia pages, but until you explained the isolation of the main CPU, with controllers for other tasks, I never understood exactly what a mainframe was. So thank you.

Also, thanks for the clear explanation of how to get started with this. I heard about the Open Mainframe project (https://www.openmainframeproject.org) and kinda poked around there, but I think I'll give Hercules a go before Open Mainframe's Zowe.

Great episode on Slackware, thanks.

I have written a guide on the post-install process here:
http://slackermedia.info/handbook/doku.php?id=user

I should probably go to the Slack wiki and merge it into the official docs, but I'm not sure what the protocol is for total re-writes of someone else's content. Anyway, it's available in the Slackermedia handbook, and covers most of the absolute necessary tasks as well as some GUI customisations.

Nice one, this will come in handy. Thank you for posting

Many years ago I was told by a professor that all really important questions come down to epistemology, i.e., how do we know what we know? I have come to see the truth in that statement. I'm glad you also see that Klaatu.

Thanks for the comment, Klaatu. I guess this works because I always pick topics I am interested in, and I suspect that is what makes it interesting to others.

This ought to be required listening for everyone before they are allowed on the Internet, or out of their front door.

My Illumos response is episode 2725. Enjoy, and thanks both JWP and ClaudioM for the comparisons.

I don't encounter CSV all that often, but this is a great tool to know about. Thanks!

I'd heard of odroid, but this has been a great review of one, with lots of useful hands-on information. Thanks for this. Eventually, I assume my Pocket Chip will die, and since the company that created it is no more, I can foresee wanting a replacement. These ultra-portable systems (some Pi-like device with a screen and some method of input) are really really useful on the 20 hour flights from New Zealand to the East Coast of USA that I end up having to make once or twice a year for some tech conf.

Thanks for yet another straight-forward and informative episode, jwp. I always wondered about the `halt` thing, since on Slackware I'd learned (probably from the Slack book) `shudown -h now`

ClaudioM: OpenIndiana uses the original Sun shutdown command (at the time of this writing, at least; I know a lot of CDDL stuff is is systematically getting replaced, but I'm not sure if 'shutdown' is on that list), and its options are pretty basic.

Oh heck, I'll just go record an episode about it.

Listening to this episode made me feel really smart, mainly because of all the science-y terms like "control group" and "double blind". Once I past feeling like I was now an expert in scientific studies, I realised that this topic is actually a broad topic and can even, in many ways, be applied to a lot of things in life, possibly software testing and usability studies. I'd love to get a job some time where I could just test people's reactions to various interface designs, or to arbitrary limitations imposed on software, and so on.

Thanks for this series; I never thought of myself as being interested in health care and science, so it's been unexpectedly intriguing.

I love this retro version of the intro music. Really cool episode, too. I was not familiar with AS/400, and I don't know much about mainframes, so this was a fascinating overview. Thank you!

Thanks for this excellent overview. I find steganography fascinating but never thought about the workflow. This episode is a great way to focus on the steps and tools involved.

Thank you for this to steganography. It is a topic that I've heard of and gave it little thought until this show. I'm interested in what you will come up with for your next episode.

It was a Novell server.

https://www.theregister.co.uk/2001/04/12/missing_novell_server_discovered_after/

Thanks for this.

I just listened to the show and immediately thought of several applications of xsv in what I do. I have installed it and am learning my way around it. Definitely a great addition to the toolkit.

On the Heartland Info Web Pages, I've posted:

"Radio Shack 150-in-1 Science Fair
Electronic Project Kit

"RECOMMENDED PROJECTS, sorted by difficulty...
with
"Additional tips..."

at: http://www.harris1.net/info/sci_tech_health/RadioShack_150in1kit.htm

It's my "Quick Guide to the best of the 150 projects in this kit, with the list organized from most basic to most advanced, of the 69 best projects for people learning electronics."

This should help electronics beginners and novices, struggling to learn electronics from the poorly organized manual -- which starts with rather advanced topics, and scatters the basics all over the place.

As a tech instructor, looking to hand my old kit of to a newbie, thought I'd take the time to sort it out for him -- and this is the result.

At bottom of chart is a lengthy collection of "tips" for novice experimenters, whether using this kit, or not.

Comments and (civil) corrections welcome.

As usual, Klaatu does an excellent job in presenting software. I particularly enjoyed when he said "You could do this, but you shouldn't." This is true in so many situations.

I wasn't aware of odroid-go until listening to this episode. Thanks for recording it and spreading information. While games are fun (I like gaming a ton), I would imagine coding for this device is where I would have the most fun. For a long time I have been fascinating about idea of taking my programs with me and carrying them around, using them when I want to.

What a brilliant tool and a great show.

This has come at a good time for me as I am deep into a large screen-scraping project which is yielding complex CSV files with many columns.

Like b-yeezi I frequently get involved with textual data manipulation in all kinds of formats. I did not know about xsv and have often had to guess the ordinal position of specific columns, and have to do all kinds of slicing and dicing operations.

Not easy at the best of times, and time consuming. All the more so if you can't easily guess the column position because you can't see.

So the timing of this show is great for me. And this is real hacking.

But I'll answer very quickly here:

1. Invoice in fiat, cryptocurrency as a medium for transfering value.

2. Yeah, that's why we didn't do that. If currency needs to be all of medium for value transfer, store of value, and unit of accounting to be currency, then most raw cryptocurrency simply isn't currency.

3. Hoo yes.

Ah I see. I always referred to the Over the Wire link I put in above.

There really isn't any other way to know what is expected of you for the level. Some levels leave you in an empty home dir. Some Levels you need info from the OTW page you'll copy/paste in.

Yes, I bet you were having quite a hard time without reading that!

I know I said, if you get really stuck, there are web sites out there with full bandit solutions on them. But, I don't feel reading the OTW web site for the level goal, then researching commands or tools to solve it on your own is cheating.

How else did we all learn any of this stuff. Figure out what needs to be done, and how a thing works, then manipulate it! Hacking. ;)

A nice, succinct episode. One thing to note, though, is that the switch for poweroff on BSD is "-p" (lowercase p) which is different than it is for Linux which is "-P" (uppercase P). Not sure what it is on illumos-based distributions since I haven't used those yet.

So I approached it from the point of view that this was a system we needed to access and had to figure out the answer without clues. I don't know where I got this idea, but I thought I heard someone explain it like that. "If you get stuck then go to the website".

So I was stuck on six for a long time as a result.

Now at 11. The problem now I searched for "some tool I know I need" plus "something I need to answer". The result was obvious but I now feel like I cheated. So am deciding if I should come up with another solution ?

I'm not sure what you mean here, Ken. Its not a question... if its a statement, I do read the website at the start of the next level.

BTW, if anyone got up to 27 last time. Well, they changed 26. So, there is a nice extra bit of challenge to that level now too.

Currently stumped on 32... for 3 days now. :P

Good fun!

You are Supposed to read the website at the start of the next level.

Sorry, Alison, I only just saw your comment.

Network Proxy configs: I don't have trouble with it, but I also have a VPN available to me; maybe that gets around some wonky network setups. I have not had a problem in airports, universities, hotels, conference centers, or really anywhere that I can think of.

Test-drive Linux in store: I do this as a matter of habit. If I'm in a store with computers for sale, I usually reboot at least one PC to Linux just to keep tabs on what works out of the box these days. It seems rare for UEFI of display models to be locked down, so I open the UEFI UI, disable Secure Boot, reboot to Linux, test stuff, and then re-enable Secure Boot to avoid what would be vandalism (I have no interest in giving Linux geeks a bad name - "keep an eye on that one, he'll break our display models until corporate sends somebody to fix them")

I've only been approached/reprimanded once for doing this. I calmly explained that I was testing Linux, which I require for work, because I was considering a purchase. The salesperson did not stand down, so I calmly rebooted and later sent an email to the store manager telling them that Linux is a real OS that real people in the area use at work, so the sales team ought to be made aware of it. I haven't had a problem since in that store (Warehouse Stationary in NZ, for the record).

Otherwise, no one has ever bothered to approach me about it. I guess if I was nervous about it, I might try to find a sales person and explain what I needed to do, and why, and then ask if I may demonstrate the process, walking them through everything as I did it. Throwing fancy words around, like "programmer" and "software developer" and "C++" might help dazzl le them into submission.

Either way, it's worth a shot.

Thanks, I'm kind of fond of the idea too. Ideas of course are cheap and actual implementation is the tricky part. But I'm trying to get at least very minimally working system up and running at somepoint. Main idea is just to explore idea of writing such a game and learn a bit Haskell and Elm on the side.

This sounds like it would be kind of an amazing game, actually. I hope it happens. If not, it's still a neat idea.

And thanks for the taste of Haskell. I've been mildly curious about it for a while, so it's nice to hear something substantial about it.

I'm glad I could be of help. My purpose in this series is to say that we can take charge of our health rather than be passive victims. Then I can offer some tools to help in that. You just need to make a decision.

Glad you found the show(s) useful and are using Bash regular expressions and capture groups.

Parsing JSON with Bash is a challenging task to take on though, I use jq to do this myself - or the JSON module in Perl of course ;-)

Very good episode about some functionality I always vaguely knew was there, but never considered using or even looking into.

Lo and behold, within a week after listening to it, I have already made use of my new-found knowledge to parse some predictably-formatted JSON!

I ran into issues with quoting the expression, and worked around them by assigned the expression to a variable and referring to that variable in the conditional.

Now I'm listening to #2669, and I understand exactly why it went wrong.

For the sake of readability, I actually think the assignment workaround was the best way to express it.

Found this and, of course, this is NOT a new idea.

https://youtu.be/SlgOsqlInpc?t=794

That I often face Ahukas shows with trepidation given I know what he's likely to say and I'm not wanting to hear it. The old "head in the sand trick worked for grandpa so it's good enough for me". But then you listen and the advice is always good and doable. Now I just feel guilt for not doing it.

Ahuka,
I have a couple(3?) of the conditions you've described and I found myself being more and more convinced as this episode went on I could make lifestyle changes, too.

Thanks, man.

Thank you for being so open with this.

I'm absolutely going to do this at home!
Thanks a lot!

Wow.

Ha!! Hilariously short, sweet, and to the point! Thanks, Ken and kids! :-)

I've never made much use of 'live' media except for installation and system rescue, but I found the ideas shared by Klaatu particularly thought-provoking. I have been travelling and wanted to perform some simple task like airline check-in from a lobby computer but hesitated over using Windows of any flavor for anything. It would be fun to at least try to reboot these machines as Linux, but don't things like network proxy configuration screw up such attempts?

It would also be fun to test-drive Linux on PCs or laptops in computer stores, but don't staff wander by and tell the perpetrator to stop? And doesn't secure-boot stop such attempts anyway?

I'm curious therefore, Klaatu, on what kinds of systems has this approach been successful? Older, pre-secure-boot PCs?

Hi Fifty,

Oh yes, English is difficult. It's rich and interesting (to me anyway) but it's a beast as well.

Yes to affect/effect. I thought it was in my list, but it was not.

British vs USA stuff: As I have aged I have tried very hard not to do the finger pointing and criticising of US English. I try to be critical across the board...!

In the 1980's I went to a conference run by Burroughs (when we had a mainframe at my work) and the speaker (from the US) said the word "instantiate". Some British guy interrupted and criticised him, saying it was not a word, only to be shot down with a dictionary reference. He looked a fool I thought, and vowed to myself never to do that!

Ken illustrated my point well. Boston Dynamics might have scripted Atlas' latest test, but there is still nice progress in the last couple of years. Seems clear to me that soon he'll be able to navigate things as they come. Same with Watson. It won't take many doubling cycles before he stops making those types of mistakes.

And with AI, robots, automation, whatever you want to call it, the knowledge is transferable. Whereas, often us meat sacks, have to repeat the mistakes of our predecessors to relearn as they did.

Seems odd to me to look back at the tech improvements in just the past 20 years and not think these areas will be vastly improved upon, too.

Loved the addition of RMS' rendition. However, I didn't not intend to replace Ken's version.

OK, probably more than one, I can see why English is so hard if it is not your first language. Amazing we forced it down the world's throat as the universal tongue, over Latin and French. Yeah team Anglo?

Anyway, in a future episode, you should reference affect/effect. I also learned something else. No American would think of using tenant as a verb. That's another elephant in the room. In the US, we reference ourselves with a term that applies to an entire hemisphere. The topic abounds on YouTube, British vs USA culture. Maybe we should open this up internationally and ask for third parties to tell us why we are both farking nuts?

This is a respond to hpr2562 :: "I bought a laptop". Tangential to the main topic, I was intrigued to learn you are paid cryptocurrency. You did not mention which type, but given the volatility in the better known cryptocurrencies, I’m curious how that might effect one’s income. I’m sending this to your e-mail referenced on the HPR website, but I’m also posting these questions to the show comments, so any listener who gets paid in cryptocurrency can weigh in. I’d rather hear from community members whom a significant portion of their income comes in the form of cryptocurrency, but maybe someone who makes extra money from a hobby or side project can contribute their tales of fortunes won and lost. At this time, I’m not asking for stories from miners or people who lost their stash do to alleged malfeasance (i.e., Mt. Gox).

1. You said you were paid in cryptocurrency. Is this in the form of you get the equivalent of X Euros (replace with relevant national currency) a week based on the current exchange rate or is it fixed at Y units of cryptocurrency?
2. If the latter answer to #1, what happens if the bottom drops out of said cryptocurrency? Are you under contract, stuck working for nothing? I guess the corollary would be what happens when cryptocurrency goes so high the company can’t afford to pay you?
3. Has volatility in the cryptocurrency market effected your financial status. In other words, have you ever made plans based on a sudden uptick in your cryptocurrency savings, only to have them dashed when the bubble burst?

Almost a year ago, my non-techie friends started asking me about Bitcoin. By that time, Bitcoin was in it’s first stages of it’s upwards ramp. I really hadn’t been paying attention, but suddenly Bitcoin was all over the news as this magical money tree that no-one knew existed. I warned my friends that I thought the bubble was speculator driven, and would burst as fast as it had inflated.

I noticed that on my shows you kept saying "we'll get back to that", but I don't think you ever did. Did you have a comment to give?

I'm glad you found this useful. That is why I record shows, to share with the community.

Thank you for two excellent tips, both how to manage youtube playlists and the Iridium plugin. It works great!

The audio is goo quiet

Wonderful mic, and VERY classy meter! Great ep, over all!

I just wanted to leave a quick comment about this show!
I think the ideas and theories you presented in this episode are very good. With the contents of this episode alone, I believe someone could make an excellent video game. You've done a good job at working out edge cases and small details to encourage learning.

A point-and-click game sounds OK, but I was wondering about what you think of these ideas in a first-person exploration game, something similar to "The Stanley Parable"?

Thank you for doing this, I love these episodes. They keep me smiling and occasionally screaming at the podcast player. You can be such a sadist, you know? :-) When describing the tuner: "It's quite interesting to hear" - "I'm not gona do that..." Please let us hear! Sure you could find a way, like letting it tune up a dummy load or something.
On the same token, please use the radio in front of you to create audible examples. How does a signal sound, that is suffering from spark distortions and how is it improved by engaging the noise blanker?

Please don't get me wrong - the one who puts out shows is right. Your show, your choice. Please keep them coming the way you like to do them.

One more comment to the content: Hearing relays clicking is not necessarily attributed to the age of the transceiver. Even in modern gear the filter in the high power transmit path are switched by relays. I have seen "Relay switched band filter." for receive as a selling point to indicate that there is no negative impact from the switching diodes. These can affect RF performance under certain conditions.

Regards,
Michael

I install and use pdftk on Slackware, so far without any issue. It's good to know about its availability in snap packages, though...just in case.

Apologies Dave, It's a bug in the screen reader: reading one ampersand where there are two.
[I must dump all this proprietary as soon as possible.]

I don't see evidence of ampersand eating. Could you point to an example?

My earlier comment #5 had ampersands galore and they are all visible, unless I'm missing something. They are being turned into HTML entities of course, but that's what you'd expect.

It's eating ampersands too! Grrrrrrrrrrrrr!

Yes, there's a bug in the comment code (or what I call a bug).

I think that, in the spirit of avoiding the "Little Bobby Tables" error the comment text is being sanitised, but the sanitisation includes backslash removal.

You can include a backslash at the moment, but you need to double it: backslash ''

We'll have a look at this issue.

Dave

Thanks to Mad Sweeney and Stuart Little for commenting on this issue.

In the light of your comments my simple tests were these:

$ [[ 'axb' =~ a.b ]] && echo "Match"
Match
- The RE on the right uses '.' as a metacharacter

$ [[ 'axb' =~ a'.'b ]] && echo "Match"
- The "meta-ness" of the '.' is removed by quoting, so no match

$ [[ 'a.b' =~ a'.'b ]] && echo "Match"
Match
- Proving that a literal match works

$ re="a'.'b"
$ [[ 'a.b' =~ $re ]] && echo "Match"
- Now the match fails if the RE is in a variable

$ eval "[[ 'a.b' =~ $re ]] && echo Match"
Match
- Following Mad Sweeney's lead, the 'eval' substitutes in the contents of '$re' so it looks to the extended test like the literal string we used earlier, and thus it works.

My working hypothesis is that the Bash logic processing this can deal with quoted metacharacters in a "bare string" but isn't used when the RE is in a variable - or maybe in any case where expansion is needed to provide the RHS argument.

You'd have to think this was a bug I guess.

The quirk Dave refers to is that you can remove the meta-status of a character in a literal RHS by quoting it so abc'.'def only matches abc.def but not abcxdef, and that it seems there is no way to do that using a regex in a variable: in a variable you only have the traditional backslash escape which you can also use in a literal regex.

--Mad

Re: the previous comment by Mad Sweeney:

You can quote portions of variables on the RHS just fine, but for the match to work the overall pattern you're trying to match must not be enclosed in *outer* quotes. So for instance, the following modification of your script works fine (matches):

---
server="hackerpublicradio.org"

for re in
publicradio"."org
do
echo "Using regular expression: $re"
if [[ $server =~ $re ]]; then
echo "This is HPR"
else
echo "No match"
fi
done
---

Note that there are no outside quotes on publicradio"."org.

The issue was visible from the echoes given out by bash. When you received the message

Using regular expression: ^(hacker|hobby)publicradio"."org$
No match

you can see bash was searching for actual quotes around the period, which of course are not there in the string $server.

It also seems like HPR comments eats backslashes!
Here's my comment showing where backslashes should be.
Would be good if there was a preview comment option:

It seems the rule of quoted literals doesn't apply if the RHS is a variable. So a variable with a quoted "." would try to match a quote followed by . followed by another quote.
If you wanted to match a quote in a literal RE you would have to write {backslash}"{backslash}.{backslash}"
A literal RE "." would be like unquoted {backslash}.
The following Bash snippet illustrates:

#!/bin/bash

v=0
for r in '^a{backslash}.b$' '^a"."b$' "^a'.'b$"; do
((v++))
# matches var 1 only
[[ a.b =~ $r ]] && echo match var $v
# matches var 2 only
[[ 'a"."b' =~ $r ]] && echo match double quote $v
# matches var 3 only
[[ "a'.'b" =~ $r ]] && echo match single quote $v
# all 3 match
eval "[[ a.b =~ $r ]] && echo match eval $v"
done

Hi,

It seems the rule of quoted literals doesn't apply if the RHS is a variable. So a variable with a quoted "." would try to match a quote followed by . followed by another quote.
If you wanted to match a quote in a literal RE you would have to write "."
The following Bash snippet illustrates:

#!/bin/bash

v=0
for r in '^a.b$' '^a"."b$' "^a'.'b$"; do
((v++))
# matches var 1 only
[[ a.b =~ $r ]] && echo match var $v
# matches var 2 only

I find the numerous ways of testing in Bash confusing. I have to look up the manual every time I come back to Bash scripting. I hope posting about it will help keep it in the brain.

I haven't played MechWarrior online or the new BattleTech computer game (although the latter one is on my list of things to try out at some point). I love seeing new games coming out for the BattleTech world and getting new fans into BattleTech universe.

Love any show that talks about slackware. The network setup you suggested is the best way to go about it but if you want to use wicd you first must install it. If you have the slackware disk its in the extras folder and can de installed using installpkg. You don't need to go out to a repository its in the installation media, just not installed by default. Thanks for doing a show about slackware, support Pat!

I'm rather confused about why there's a reliance on any particular java runtime, but at least on debian, if i request pdftk to be installed, pdftk-java is installed, and yeah, no screwing around required.

It's a shame that PDFtk is basically going away because the GCJ runtime has been deprecated by most major distros. PDFTK still lives on as a Snap. Also, there is a fork that uses openJDK instead. You can reference this Stack Overflow post:

https://askubuntu.com/questions/1028522/how-can-i-install-pdftk-in-ubuntu-18-04-bionic

Sorry about that.

If you have any particular systemd problems, I could be poked into recording a show to help out with them?

Its an interesting topic you bring up. personally I am appalled by scarecrow tactics. I'd like to offer a different view. There is lots wrong with capitalism. First thing is that capitalists believe their system is the only answer. The hangover after our last industrial revolution gave us shorter working days, safety rules and employee rights at work. Currently there is lots of demand out there for sabbaticals or people taking a break. so hell yeah, give me a robot who does my job so I can recover from stress, spend time with my children or travel, do volunteer work. Why do we doubt Basic income? currently those breaks are only available for the rich or singles or childless. Have you seen a happy cashier? Have you heard a mine worker shouting: yes - let's continue ruining my lung instead of giving me proper training so I can work in a solar panel farm. and for the doctors! I have met so many who were an utter waste of my time. yes, give me the Watson system. I had to retrain in my job 3 times over the last 6 years. it has been hard. it doesn't have to be! As you say, Robots give us an opportunity to focus on the things that matter in life. We dont have to run anymore all the time. Robots guarantee a basic level of productivity. We can find better and creative solutions to provide proper pay for people who work in the care. We can focus on figuring out why our society still struggles with all kinds of abuse, why we do not trust anyone, why we feel the need to destroy our beautiful world. we have a universe to explore and the complex systems in our world. and if there is the odd person not willing to work, then that's okay too. People have reasons! Capitalists only know the word more. When will you read all the books that keep accumulating on your bookshelf because you shouted MORE. There is no time because I have to be social, I have to take care of children, because I have to declare taxes, have to have that lawsuit with my neighbour, have to go to work, have to cl

Here's another show I've recorded but didn't publish. I am in the process of editing this one though. You do a better job than I do, however. Perhaps I should sit back and revel in the fact that you're pulling my weight!

I enjoyed the show, and obviously agree. I'm still going to submit my episode; but will edit it touch on things you didn't.

I really do wonder if people can look at the rate of change in the rate of change and not think that it's accelerating and just about everything that looks too pitiful now to take over our jobs, will continue in that state forever.

In my mind you only need to look at Boston Robotics. People were citing the fact that Atlas kept falling over as evidence that he'd never perform as well as humans. A couple short years later and he's performing feats similar to parkour.

Can we really not imagine how a couple of cycles of Moore's law's worth of improvement looks?

What an improvement! I confess, I couldn't even finish the last ep due to the audio quality (and my standards are low), but this episode has fantastic sound. Great job!

Thank you for your comment! I'm glad that this episode still makes sense over five years after it was recorded.

Great tips. Seriously.

I need to temper this show with our HPR motto of "any audio is better than no audio.". We always put content over audio quality.

While this may loose us listners, it gains us hosts.

Sure always try and record the best you can, but dont ever let it get in the way of submitting the show. Perfection leads to procrastination. "It aint a show unless its on the server."

Do you have any ideas on how to solve these problems? I'll crawl under my rock now.

Great show, it's good to know there are other fans of Battle Tech out there! Do you also play MechWarrior Online and howndonyoi feel about the latest entry in the Mech Warrior single player game?

Jonas, thanks for sharing your method. I like the way you put the cinnamon right into the batter, instead of using it as a topping. I also liked your tip of using a cake decorating bottle.

lostnbronx, I am glad you got a good breakfast out of my episode.

I never thought of making the cinnamon sugar with brown sugar! I have always used white sugar. I'm going to try your way when my cinnamon sugar container is empty.

This is so good. Thanks for the show. I always wonder how other people make similar things I like.
As it happens, I just made crepes yesterday.
I have no idea why my Texas mom started making crepes, but I just remember having them at home as a kid.
I don't know if what I do is technically called a crepe but it's very crepe like, or maybe more super thin pancake like.
I'm not much of a measurer. I typically start with 1 to 1.5 cups flour and add a couple table spoons to 1/4 cup of sugar depending on the day. I also add lots of cinnamon. 1/4 teaspoon to a half table spoon. Again depending on the amount of flour, the sugar and cinnamon increases.
This is basically a dessert crepe.
After whisking the dry together with a 1/8 teaspoon of salt or or less, I add 3/4 cup of milk. If the mix isn't watery enough, add more milk until pretty thin. Then add an egg and beat in completely.
I have a gas stove, so I put the flame on to just above as low as it can go without going out. I let that heat a stainless pan for several minutes, while putting the other things together. More flame if you know what you're doing. You want the pan to be the right temp before putting in the first drizzle of batter.
I like to use a cake decorating bottle to put the batter in the pan. Get the bottles at Ross, a discount store, or at the dreaded Wal-Mart. You could probably enlarge the opening on one of the $.99 ketchup/mustard squeeze bottles, but they are not clear like the decorating bottles.

Just before putting the batter in the pan, swirl around then end of a stick of butter just enough to wet the pan. Start at the center of the pan with a splash of batter making an ever widening circle until you cover 2/3 of the pan. If the batter is thin enough it will spread itself. Otherwise you can pick up and jostle the pan to flatten more. I generally cook until the edges curl and the top starts looking less wet, then flip and cook the other side 10-20 seconds to firm up top side.

I just made a simple breakfast using your recipe. It was easy and delicious. I used brown sugar and cinnamon, and it was a hit. Great content, thanks for uploading!

This is a fine beginners list. It hits all the "big pieces" of the tools set and forms a solid foundation for continued learning. This is neat, succinct, and is an outstanding resource. Thanks for putting this together.

Top Man!
Many thanks for posting your information regarding systemd services. I've been pulling my hair out trying to work out why my pre-shutdown script would not fire. Then I found your post.
A very big thank you to you.

Hi NYbill many thanks for the comment glad you liked the show, yes as you could tell from the show I didn't know what a few of the controls did, so it will indeed be bewildering to start with. I've tried to fill in some of the gaps in the show notes,

All the best

Mrx

Hi thelovebug, many thanks for the kind comment glad you enjoyed the show, yes I couldn't believe what a difference it made swapping microphones.

Hi there,

i just listen a second time and say "Thanks for the effort made."

Ken, are you just now getting around to listening to this episode? Whoever thought this old thing would get brought back from the dead haha! Anyway yes, counterpoint is the art of combining melodies. :)

I never listen to my own shows via the feed, so I never listen to my whistling outro either.

As I hear it now, man does that bring back memories. I remember exactly where I was walking on the way to my bus to work as I was recording it. That was three homes, one country, three offices, three kindergartens and three years ago.

I can feel the chill from the November morning fog around Järfälla Church on my cheeks as I'm typing this.

I know that I accidentally set the sample rate too low when I recorded it (11.25 kHz, I believe), but hearing it now that sound quality is worse than I remember it. :-)

We could still allow people to add arbitrary intros, and just not do TTS-over-intro in those cases. But the idea to do TTS-over-intro on a list of prepared flexible-length intros is really cool.

As for me though, as you have noticed on my shows, I really like having a standardized intro as the unified HPR brand, while allowing some variation at the end.

I think I have to do a show on the whole issue of loops in pipelines. It's been in the "topics to cover" heap for a while but now it's being re-prioritised! I'll probably make it show 14 in the "Bash Tips" subset.

While it is true that we hosts could do more to manage our sound levels, the facts on the ground are that the intro music is louder than the average show.

I have thought often that the intro volume should be a bit lower, but never said anything.

That explains why it's a "stoop sale"!

(which is a garage sale, which is like a yard sale, if you live in Brooklyn ...)

I've stopped listening to Kvack! too. I like the people, and I enjoy listening to them hanging out, but in the limited time I have and the massive amount of content out there, that's not enough to put the podcast in the queue. It's too much opinion and too little education and insightful analysis.

I quite like http://theesp.eu/ as well, but it's also far from SGU levels in relevance and production values. Unfair perhaps, as SGU has over a decade of podcasting under their belt, but that's how it is.

Excellent pronuncation, Dave! You're spot on.

Compared to "kvalificerat hemligt", "skeptikerpodden" is trivial to say. :-)

As Dave points out, the while loop you describe would work if it weren't for ls issues. Here's what doesn't work:

items=()
produce_items | while read item; items+=( "$item" ); done
do_stuff_with "${items[@]}"

Oh, how many times I have made this mistake.

"items" gets updated just fine, in a subshell, and then after the pipe has finished executing, execution continues in the parent shell where the array is still empty.

Null-terminating and giving "read" the appropriate parameters is an HPR episode of its own, no doubt already made by Dave, or in his pipeline. ;-)

Hi, Ken! The following link will tell you more than you ever wanted to know about bagged milk. :) This is how milk is generally sold in Ontario, Nova Scotia, and New Brunswick, and probably in the other Canadian Provinces and Territories as well.

touché

@Ken and @Dave
Take your comments and make a collaborative show of the material ;-)

I actually wrote:

_ffmpeg() { printf "ffmpeg %s %s %s
" "${@}"; }

but something removed the backslash.

I think the thing to take away is: Don't use 'ls' for this purpose. I might have said that before ;-)

One way to debug your problem (should you feel that avoiding 'ls' is not enough) might be this:

1. Create a function to display the arguments:

_ffmpeg() { printf "ffmpeg %s %s %sn" "${@}"; }

2. Run your pipeline thus:

ls *.mp3|while read i;do _ffmpeg -i "${i}" "${i}.wav" 2>&1;done

I tested things like this:

$ cd /tmp
$ touch {a..f}.mp3
$ ls *.mp3|while read i;do _ffmpeg -i "${i}" "${i}.wav" 2>&1;done
ffmpeg -i a.mp3 a.mp3.wav
ffmpeg -i b.mp3 b.mp3.wav
ffmpeg -i c.mp3 c.mp3.wav
ffmpeg -i d.mp3 d.mp3.wav
ffmpeg -i e.mp3 e.mp3.wav
ffmpeg -i f.mp3 f.mp3.wav

The names like 'a.mp3' are all coloured blue.

If I use the real 'ffmpeg' I get (output heavily truncated with only one file shown):

ffmpeg version 4.0.2-2 Copyright (c) 2000-2018 the FFmpeg developers
built with gcc 8 (Debian 8.2.0-7)
configuration: --prefix=/usr --extra-version=2 --toolchain=hardened

[snip]

libswresample 3. 1.100 / 3. 1.100
libpostproc 55. 1.100 / 55. 1.100
?[0m?[00;36ma.mp3?[0m: No such file or directory

The codes before and after 'a.mp3' are colour on/off codes.

Your environment will certainly be different of course, so your failures may not be the same.

Clear?

Polyphonic had a video about Scarborough Fair/Canticle: How Simon and Garfunkel Created a Timeless Song, and it struck me what counterpoint was.

I'm not sure you're cleare enough about using ls.

It fails as it only does one mp3, while while does them all.

ls *.mp3|while read i;do ffmpeg -i "${i}" "${i}.wav" 2>&1;done

You don't say how this fails, but there are several reasons not to do things this way:

1. It's unwise to feed a 'while' loop thorough a pipe because the 'while' runs
in a separate shell which can lead to problems

2. Never use 'ls' to get a list of files for consumption in a script. Unless
you can be completely sure that the 'ls' you are using isn't adding suffixes
like '@' for links, and '/' for directories and isn't adding colour codes to
the names, don't do it. Much better to use 'find'.

My test with this pipeline returned colour codes which 'ffmpeg' didn't like,
and it failed that way.

for i in *.mp3;do ffmpeg -i "${i}" "${i}.wav" 2>&1;done

This doesn't use 'ls' it simply uses file expansion therefore no additional
filename garbage!

Did I mention: don't use 'ls' as a way of feeding filenames to a loop or
whatever?

The first example would have worked if you'd written:

while read i;do ffmpeg -i "${i}" "${i}.wav" 2>&1;done < <(find . -maxdepth 1 -name "*.mp3")

The '-maxdepth 1' option prevents 'find' from going into sub-directories. The
'find' is inside a process substitution which is redirected to the 'while' so
the 'read' inside it can obtain what is produced on its STDIN channel.

Also, if it had been me I'd have written:

ffmpeg -i "${i}" "${i}.wav"

as:

ffmpeg -i "${i}" "${i%mp3}wav"

to avoid the output files being called 'xxx.mp3.wav'. I spoke about this in my
"Bash Tips" show http://hackerpublicradio.org/eps.php?id=1648

Dave

This fails

ls *.mp3|while read i;do ffmpeg -i "${i}" "${i}.wav" 2>&1;done


This works

for i in *.mp3;do ffmpeg -i "${i}" "${i}.wav" 2>&1;done

Yea, do continue this series. I recently got my Tech license. I'll go for the General soon.

Its nice to have someone explain what you might see if/when you get an actual radio. Because, walking into this cold, it just looks like a lot of buttons!

What pray is a milkbag.

Also soundscape tour of the falls please

Yes, I did listen to Skeptikerpodden and I miss it. For some time I listened to Kvack! after it ended, but that's not really a good replacement. To be honest, Kvack! is one of those podcasts I meant with "got tired of".
We really need some podcast in Swedish (and German too) in the tradition and quality of SGU.

These troubleshooting shows are one of my favourites. I did tinker just a tiny bit with electronics at school, but never invested enough time to really understand what electricity is all about. Especially the analog electronics is sort of black magic to me :)

But I love listening when someone is working with it, explaining what they're doing and slowly working their way through a problem.

Ha ha, nice job Ken. It made me smile when I heard you happy it was finally blinking. And we got some live troubleshooting as well! Good stuff.

You know how I remembered which way a LED went way back when... One leg of the LED is cut off. 'Cut Off' starts with a 'C'. So does Cathode. The short leg is the cathode. If you had your leg cut off, that would be a pretty negative thing. The short leg is negative.

Just a little mnemonic device I made up to help me remember. I still think of it to this day.

Now, you just need to build one of the oscilloscope kits. You know, to see how fast your LED is blinking.

See how I did that? Its how we get more shows. ;)

Ken: Yes the arithmetic stuff evaluating to true/false is a bit counter-intuitive I think. Yes, grep is quite a powerful tool for use in scripts.

johanv: Glad you found the show useful. I'm trying to explain things that I never fully understood before, and to share what I have found as I do so.

I hadn't listened to HPR for a long time, but a couple of days ago I had some spare time, and I decided to listen to this episode. I liked it a lot, and today I am a little more aware about what I am actually doing while writing if statements with those square brackets in bash, and checking return codes.

Thanks for the interesting show!

I'm a tool person, so I really like the idea of using your tools to push yourself forward in your language learning. It's hard to say how it would turn out in practice, but I'm optimistic.

As you mention, mixing vocabulary in languages that have very different grammars could become a bit strange, but code-switching -- that is, jumping back and forth between languages - is common and frequent with bilingual people, and it frequently happens mid-sentence, so I guess that just shows that people are pretty good at making it work even in radically different languages.

The area where I live has mostly Chinese Hongkongers, but many of them speak a lot of English in the office and at home, and it's pretty fun to listen to the kids on the playground and in the playroom talk to each other -- it's a real soup of Cantonese and English.

Thank you MrX for that lovely accordion outro. Hadn't heard it before!

Oh, and I love Kvalificerat hemligt (and I love that Ken or Dave is going to have to pronounce it when reading this on the community show).

Did you listen to Skeptikerpodden back when it was active and CJ was one of the people involved? That was a very good show, and I miss it.

Now that's how you don't waste a good opportunity to make an HPR episode. I am observing and learning.

Never heard of Q before. Very cool! I will very likely find use for this.

Not a very googlable name, but I found it here: https://harelba.github.io/q/

Good to hear from you again. I really enjoyed this episode, the audio quality was definitely on point... those little lapel mics are great!

Don't worry too much about the structure of this episode, you were recording to make a point and you made it really well.

With Nix 2.1 ( https://nixos.org/nix/manual/#ssec-relnotes-2.1 ) reading TOML files has become a builtin function in Nix, just builtins.fromTOML /path/to/the/file.toml .

I can't imagine this being unrelated to Mozilla's implementation in Nix.

I installed Ranger after listening to your show 1756 (http://hackerpublicradio.org/eps.php?id=1756) but never used it and completely forgot about it. I was surprised to find it on my system and have been playing about with it a lot since listening to this show.

I'm a long-time text and command-line user but I tend to use Midnight Commander for the times I want to do a lot of file searching and manipulation, though I have to admit I use Dolphin sometimes in two-pane mode when I'm doing things like copying files off an SD card. I shall add Ranger to the mix too I think.

I agree with Ken: we need shows about all of the tools in your list!

Anyway, this was a very welcome episode. Thanks.

I'm a die hard vimmer and have never heard of Ranger. I'm looking forward to using it more. I asked a couple of my online Linuxey buddies and they used it years ago when they had less substantial machines. I still love the command line stuff even with my best machines. Everything is super quick in the terminal.
Thanks for the mention and your great shows.
I need to explore jq for sure. I work with a database that saves a couple columns in JSON. It would be nice to query the exports in a more friendly way.

I'm a big fan of plain text and CSV files, as they are probably the formats that will last conceptually forever - unlike the Office formats we use today (including ODS/ODT etc). You may lose the layout information but the "meat" is always preserved.

The PDF to Text converters only work with documents which have been generated from a WP application. Scans of a printed document generally only produce an embedded JPG image.

A few years ago I created a system that employed many of the commands you mention in your episode to convert a document into pure ASCII text, then create a non-repeating list of all the words it contains, along with an instance count (using SQL). By applying this to the contents of a document library the database was used to populate a "search by keyword" system for that library.

Populating the database from several hundred Word and PDF documents took only a couple of minutes. The subsequent keyword searches were very fast and produced a list of relevant documents ranked by the number of instances of the keyword. It was very easy to combine keywords using SQL "AND" and "OR" qualifiers.

Always knew I needed spaces now I know why.

The evaluate zero thing seems strange.

Note to self: stop using wc -l to count grep output.

Those that I know I use literally every day. Can't wait to try the rest out.

Please do a deep dive series on each. No pressure.

very interesting. i love xoke's stuff

Thankyou Ahuka for your bravery, honesty and openness on this subject.
HPR has a broad spectrum of listeners though one suspects many are people who, though younger than yourself, are acutely aware of a family history of certain cancers. This show gave a great insight into what one should expect if a diagnosis becomes a pressing concern, particularly with the state of modern medicine.
Also thank you for reiterating, one should always consult a medical professional for advice upon which to make a decison about treatment or any other course of action.

Ohhh... this episode brought back pleasant memories when PCs were just “toys” made to run WordPerfect, Lotus123, Harvard Graphics and Attachmate Extra TN3270 emulator. Thanks for the ride.

Code for this episode is now at Notabug.org

Hey, just wanted to let you know I thought it was a fun and interesting show.

Thanks also for the mention.

Hmm, can I do this...Just wanted to add my two cents on the front notices to podcasts. I like the espeak announcements. Considering I'm a blink that may be why. The theme music would be nice to have alternating versions to make them less tedious.

Hey, just wanted to let you know I thought it was a fun and interesting show.

Thanks also for the mention.

Your descriptions were excellent and enjoyable. Thank you very much
for sharing the trip through town with us.

Enjoyed the show but given they fact I'm a long time hercules user and a grey beard mainframer I'm embarrassed I didn't do this show! Actually, I recorded this show more than once but thought it wouldn't make sense to someone new to the mainframe.

I think you handled that problem well. Maybe this will inspire me enough to create some mainframe shows.

I agree the moshix youtube channel is worth checking out for anyone interested in the mainframe.

A "stoop" is a set of cement steps up to your front door - not as big as a "porch". Hmm, not sure if it has to be cement.

If this ain't what hacking is about, then hacking ain't worth a plug nickel.

But what the hell is a stoop? Think we need an American/English dictionary here :-)

Thoroughly enjoyed this episode. Due in large part to remembering the times read or listened to people talking about similar things in my youth. I did try some of them out but mostly read or listened to people describing the experience.

While I listen to ALL episodes of hpr, Sigflup is on my 'must watch NOW' list. This one delivered in spaces for me. Not only was is fun to listen to, but I have similar equipment I've been meaning to do something similar with.

There goes my last excuse.

My only regret is that after the excellent real hacking phone shows from the last two days, my horrible by comparison drivel is up today.

Sorry about that.

The best part of this wonderful hack (IMHO) is that you created something and then used that something to record an HPR episode.

This is the definition of hacking. I loved how you described your problem solving process. More of these, please!

Seriously a joy to listen to.

Brilliant show. This show is the real definition of hacking.

If I have this right, you found some Cisco phones in the garage of a neighbour and set about getting them to do something useful.

The joy of getting something to work is obvious from your tone of voice and your dialogue. Something that we all no doubt can identify with.

All the more satisfying when it is resurrecting something previously discarded

baffled,
You make fewer screw ups than I do.

I'll take a look at the Michell Thomas Method.

I would definitely put time into developing this out if it seems like there's enough people willing to spend some time. Two might be enough. A couple more couldn't hurt.

Encore!

This is my first time commenting so I apologize in advance for any screw ups.

I believe your point one to move to the new language as soon as
possible is an excellent idea. I'd also be interested in helping with
developing and discussing it should you decide to persue the notion.

There is a great book "The Future of Learning - the Michell Thomas
Method" by Michell Thomas Where he discusses his perspective on
education that I recommend as an interesting read.

This was a great episode, thanks!

Yesod seems like a great option for high-concurrency web applications. Thank you for introducing it to me and the rest of the HPR community.

Did we forget to include the script itself ?

Hi klaatu,

Thanks for this heads-up. It *is* a confusing feature of awk, but it's the same for sed (so at least the authors are consistent). I don't think we have emphasised it enough, on reflection.

It was highlighted in show 2 of the Awk series (http://hackerpublicradio.org/eps/hpr2129/full_shownotes.html#more-about-awk-programs) and has been used many times thereafter, but hasn't been emphasised.

So, thanks again for the feedback. It's most appreciated.

Dave

Thank you for this, I appreciate your openness and the details.

So glad you enjoyed this. Once you start looking around on the internet at vintage tube radios you find that there are TONS of these things, and the photo galleries are serious eye candy if you like mid-century modern industrial design. They also have lots of tube-powered clock radios like you described. Wish I had the money and the space to start collecting these things!

Steve, Glad you enjoyed the show, it was an enjoyable interview to record.

What an awesome looking radio. You brought back several memories for me. I vaguely remember my dad having an old stand up unit in his barn/workshop. I had several push button channel selectors. Also, I once had a table top tube am radio with a clock (about the size of a toaster). Then lastly, your station playing "Dark Lady" Wow, I had that on a 45 (if anyone remembers those kind of recordings. Thank you Jon for the memories!

Thanks for doing this interview. "Concrete Dog" looks like someone I could get along with quite well.

This is a quote from Klaatu today on Mastodon.

"Also, English is the worst language. I wish we'd migrate away to something constructed and better, like Esperanto."

MegaMek and MekWars I completely forgot as I was do excited to talk about the game. Truth to be told, there's so much to tell about the game that it's almost impossible to fit all of it in one episode even in a very superficial level.

For a complete rundown on the when, what and how of SparkleShare, see klaatu's http://hackerpublicradio.org/eps.php?id=2609 .

Excellent show as always! What SparkleShare is and how to use it at different expert levels, and when not to use it at all, is all thoroughly explained without the episide ever feeling long.

But most of all, thank you for paying off my episode debt to the community for me. I guess I owe you personally an episode now instead.

I haven't listened to the podcast yet but I have it queued for my morning walk. I hope you mentioned MegaMek and MekWars. As an avid btech fan, it's about the only way I can play these days because it's hard to get a tabletop game together sometimes.

Thanks for this episode. I've heard of processing, but never knew what it was or how it could be useful. I will probably turn to this after scratch for my kids.

Yikes. I really don't have much to say. I used to run away as a kid to get treats from the store next door, no trains nearby though..

Brenda,
That is annoying! What I try to remember to do is to ask in the format of "Don't spend time on this but do you know off the top of your head?"

But recently, I asked someone a question I'd already spent a lot of time researching and it appears that I couldn't do what I wanted to do.

But, as I said, if I think something should be possible, I won't let a 'No' remain so and will ask again every few months. Even if it's a 'No' now, things change quickly.

Anyway, I forgot to add 'off the top of your head' and I'm afraid 1-2 hours might have been spent searching for me to return the first bit of text my researching revealed.

I feel so bad about that slip of the tongue.

I totally agree.

And another thing that is annoying is when you ask a question and the person doesn't know the answer but either tells you a bunch of generalities that anyone would know, and/or tries to find the answer while you stand there, when you could go back to your desk and look for yourself. What I would like is a quick answer, even if it is "I don't know" or even "I don't know off the top of my head". They could throw in some keywords to search for, if they think it might help.

Haha! I hadn't quite looked at it like that, but you are right.

I like looking for logicality in language. Sometimes it's a vain search (as I'm sure @klaatu would say), but a fair bit seems to conform to _somebody's_ idea of logic.

There are lots of issues with how we ask and answer questions but related to humiliation specifically, what makes me really sad is when someone tells me they don't want to ask a question because the person or people they'll be asking humiliate them.

One of the reasons I will not publish the asker's name if they don't me want to.

I first this seems like a weak person, but I've had managers tell me the look down on people who don't know things. So I understand the hesitation to ask questions in an unfriendly environment.

There's a lot to learn and we might all be better off if we realize the person has skills, just maybe not in the same area you do.

Enjoyed the podcast.

I find it to be very frustrating asking technical questions because a lot of guys want to humiliate people who ask them questions. Like Nick Burns. And I find that these guys often don't actually answer the question, because they aren't listening. They just listen until they hear a keyword, and then go into a rant.

I won't hear this till tomorrow, while driving at work. But, it is fitting that it happened to come out during the Hackers On Planet Earth conference. :D

I am fascinated by etymology. I learnt a lot of spelling and pronunciation by understanding word origins as a youngster, and spent a fair bit of time looking stuff up in a dictionary to find etymological information. I will try and share some of the historical context as I go for certain.

I studied what was being called "Comparative Psychology" at university, and this involved looking at some of Chomsky's work. I wouldn't say I was very familiar with it now 40+ years later, but I'm prepared to have another look.

I expect these shows will become a series soon, and you will be very welcome to contribute to it. You are welcome to contribute now!

I loved learning that the ownership-form of the apostrophe is really another example of a contraction.

Thanks for this podcast. I've run into the same problem. Once I cleaned my remote about three times it was done. The "gunk" in the remote that gets on the circuit board is generally some kind of silicone lubricant or solvent. Apparently, the button pads have to be cooked after they are made to get all the silicone gunk out, and most manufacturers don't bother any longer, as they assume you will only use the remote for a year or two before losing it (or you'll just buy a new one?).

The actual, physical act of pressing the button pushes the silicone gunk out of the pad.

Thanks for the guitar pick trick!

I am pleased you responded with more etymological information. For some reason, knowing that kind of history really brings these things alive for me. I am enjoying the series.

I hope at some later date there might be a connection to regular grammar and regular language. I've always been fascinated by the connection between Noam Chomsky's linguistic work and the simultaneous development of Lisp at M.I.T.—both endeavors being obsessed with recursion.

The Fraunhofer Institute's US patents on mp3 have expired, so the mp3 format is no longer problematic in connection with free software.

The only reasons not to use mp3 these days are because it's two decades behind in codec evolution (e.g. Opus is strictly better in every aspect) and in envelope evolution (e.g. Matroska has better metadata and streaming facilities).

There's no doubt (in my mind anyway) that English is weird and difficult; annoying (at times) and illogical. Possibly because I was a bad student at school in my teens, I have never properly understood the whole issue of grammar, parsing sentences, past participles and all of that. However, I have always had a fascination with words, their meanings and their origins, and I think it's English that has led to that interest.

Other languages also have their problems. I learnt French at school (and did a few years as an adult too) and never got to grips with the genders of nouns. Why is a table (furniture) feminine for example? How is it possible to remember them all? I still enjoy attempting to speak French nevertheless.

You point to the deficiencies of English with regard to the meaning of "free". Absolutely. That's a shortcoming. However, many other languages have their own idiosyncrasies. I worked at a university with a campus in Kuala Lumpur, Malaysia. Bahasa Melayu, the local language, has a very different grammar compared to English. See https://en.wikipedia.org/wiki/Malay_grammar for some aspects of it. I remember having conversations with Malay speakers, suggesting a English way of expressing a thing, to be told that that was pretty much impossible in their language. This led me to believe that English might be more subtle; though perhaps on the other hand it's more suitable for circumlocution, evasion and indirectness!

At school my French teacher was also an advocate of Esperanto. I wonder if that sort of language was what you had in mind instead of English? I don't know enough about its benefits to judge, but I wonder if a constructed language can really be as rich as a "natural" evolved language - even with all of its clutter and detritus.

Thanks for your comments - they really got me thinking.

Loved this episode, Ken! Wish I would've thought about this before purchasing TaoTronics TT-BA07. I like my little device but I prefer the DIY way!

My rockbox sansa device is still alive but my dad's bit the dust. I'm hoping mine keeps going, though I am often using my android phone and this adaptor these days.

This is such a great series. I can honestly say that, having spoken fairly proper English for my entire life, I hate the English language. Of all the languages poised to serve as a global language, there could not be one more undeserving than an amalgamation of Germanic forced through a filter of Latin. It's inconsistent, confusing, over-complex, and yet also insufficient (see the FSF's struggle with the lack of an adjective form of "free" for an example).

I really wish a sensible, constructed language would be adopted in English's place.

Anyway, nice series, although your efforts are surely in vain, because English will never make sense.

Great episode. I loved your use cases, and the walk-through of using the tool. Also, I tried nmtui out for myself and it is actually quite useful. Network configuration is such a bother, so it's nice to have an "easy" button with tools like these that still don't depend on a Xorg/Wayland/whatever.

Thanks for the comment, Klaatu. I'd like to hear more discussion about this, too, especially any arguments about whether saving money is really necessary or not. I have at least one colleague at work who rides his bike 4.5 miles each way (and has for the last 20 some years), and he says that he does not save for retirement because his retirement plan is to get hit by a Suburban on the road. I think he's only half kidding.

I've seen lots of miniatures in the past and wondered what goes on in the mind of those who point them. Now I know. Thanks for the insight.

You make some really great points. Thanks for taking this discussion farther. I'd be interested in hearing about more people's experiences with saving money, too, because I don't think there is just one right answer (or, arguably, the obligation or ability to save at all, if somebody wants to argue those points). The morality is interesting to me, too. It seems like the only way to "grow" money requires either contributing to something one doesn't actually want to support, or else taking advantage of others.

Basically, this is a huge topic and it's one that is getting more interesting the more I hear other people talk about it.

I'd never seen an on/off switch on an electirical outlet until New Zealand. Here, every electrical outlet has a dedicated power switch so that you can plug in a device and then power it on. It's really useful.

In the USA, I think the only way to simulate this is to use a power strip (sometimes a surge protector, other times just a splitter, which often have switches on them.

Haha!

Isn't that like that line from that Star-Trek-Wars film: "Leverage the Force Luke!"?

No, I'm wrong, that's a verbification I think...

Thanks for this episode. I'd heard of Edge of the Empire but have never played. I really like your character build process, and this was a nice overview of how characters work in this system. Thanks1

I see amazing painted minis at my local hobby shop, and it always makes me want to get into creating dioramas and battlefields for games, but I don't feel like I have the time,money,or space for it. Thanks for letting me live vicariously through your hobby in this episode.

see, vision, eyes - get it ?

John, how weird that I pick a random podcast to out of the lineup to listen to and find this one on feedly. I didn't even see the Juiced Penguin in the title this morning when I started listening. Heck, it's not even something that I think about these days.

The Juiced Penguin was an idea that I had, and knew that I couldn't pull it off alone. - The Late Great Lord "D" assisted me with the original effort. It took a lot of time to find the music, and Klaatu assisted with offering up some content for it also. I found that it was really time consuming, and Terry F took over for a period of time until it fizzled out.

The main idea that I had was to get more OGG content out there, to help expand the awareness of the OGG format, due to restrictions of the MP3 format, and that many MP3 Players didn't support it. - Today, most people are listening to content on computers or Android devices, most are able to listen to the ogg format, if they wish.

If my ol' memory serves right, even Mark Shuttleworth has stopped worrying about the MP3 format being a real problem, even tho' it's still a closed file format. Granted it's not open, but the threat of being sued doesn't seem likely after nothing happening after all of this time.

- FWIW, when I AM online I'm easily found over on G+ aka randynose.com Also over on Mastodon.Rocks @randynose.

Thanks for reminding me of some good times years ago...

All hail the Juiced Penguin. :)

Thanks JWP, I'm glad at least one listener found it useful, having been using it for a good couple of months now I can say I am very impressed and have even found a work around for the usb utilities I use in mint. I have installed Mint 19 beta into virtual box and it seems very good and once the stable release is out it will still be my go to distro for installing for family and friends who are not Linux gurus. Ubuntu Mate will probably remain on my main box until the next LTS cycle as I try and keep that as stable as possible and change OS on it as infrequently as I can get away with.

...I found this out by accident in my youth. You can also point the remote at an electric guitar pickup while its plugged into an amp.

dit dit dit dit dit dit dit!

Add distortion or reverb to your liking. :P

Great show - only one point.

We do not "approve" shows, we process them. See

http://hackerpublicradio.org/stuff_you_need_to_know.php#not_moderated

Your show will not be moderated.

We do not vet, edit, moderate or in any way censor any of the shows on the network, we trust you to do that. Aside from checking snippets for audio quality/spam checking, we have a policy that we don't listen to the shows before they are aired. This is a long standing tradition arising from the fact that HPR is a community of peers who believe that any host has as much right to submit shows as any other.

hpr2210 :: On Freedom of Speech and Censorship describes the agreed approach to this topic.

Hi klaatu always interesting to see what you will bring up.
I to for a long time when cash only. I do keep a card in the glove box or bring it traveling but I find I spend less if I just use cash.

Also if you can -- I really enjoy many of your topics. -- Might you get a better headset sometimes its hard for me to hear exactly what you say. (Audio quality between Jupiter broadcasting and Dave Morris quality would be greatly valued.)

Tony always so nice to here from you again.
Sadly I am driving any Mate right now. Only two 16.04 boxes maybe after 16.04.1 thanks so much for the update

Thank you, Clinton Roy!
That one I didn't know. I found their page http://omegataupodcast.net/ and shall give the dual-language feed a go on my serverlist: http://omegataupodcast.net/category/podcast/feed

I quite like the omega tau science & engineering podcast
podcast, it comes in both english and german forms, I don't think they translate the content, it's just different stories for the different language podcasts.

Love that concept.

In my case I use tab groups to keep useful and related web sites together to make "context switching" simpler. For example, in Pale Moon I have a group per HPR series or project, and when I'm in the mood to prepare a new HPR show I run it on my right-hand monitor with Gvim on the left.

I usually have Vivaldi, Chromium and IceWeasel running on different XFCE desktops as well, and all of these have pinned tabs so I can easily visit various HPR pages, the most used pages on my local MediaWiki instance, GitLab, GitHub, archive.org, Telegram groups, and so on.

It's probably (barely) organised chaos, but I like it ;-)

That's a great suggestion. I spent some time looking at the etymology of the words I was talking about, as you can tell from the links, but I didn't consider talking about the subject. I'll mention such things in the future if it seems relevant.

Thanks for the feedback.

Apparently I didn't explain what SparkleShare is!

It's "DropBox for git". You tell it where your remote git repo is, and it keeps an eye on it and keeps a local directory in sync.

Whenever anything happens in the remote repo, it pulls that change and makes your local sirectory the same.

Whenever you add, remove or edit a file in your local directory, it creates a commit for your change and pushes it to the remote repo.

Any conflicts that occur are resolved by creating a file named something like "myfile conflicted on 2018-06-15T16:57:45.txt", so you never have to understand anything about git to use SparkleShare. Just play with your files in your directory.

That's why it's so good for dads.

It seems this is the month of clarifications, judging from the feedback from Ken and Dave on the Community News. :-)

I'm adding a deeper Stow show to my future shows tag.

But for now, here's what Dave was asking for:

Stow doesn't use any configuration, it's all simple, hard-coded behavior. When it stows things it puts things in the parent directory of the stow directory:

If your are in /home/clacke/stow and you do stow foo, any stuff in e.g. /home/clacke/stow/foo/lib gets symlinks in /home/clacke/lib .

I forgot to mention the killer feature, which is why we use Styx, apart from our great love for Nix: The ability to easily include content from remote sources.

As Styx uses Nix for getting its inputs, it's just as easy to build a page off a file in your local repository as getting a file from a remote repository, http URL, a whole bunch of files, or anything you can compute or get from a network, really.

In fact, even the default templates in Styx are fetched this way: If you never use them, they never touch your computer, but if you include the standard templates in your site definition, Styx knows to go out and fetch them and put them in the right places.

We use this to get documentation and changelog from our code repository into our web site.

As noted on May Community News[0], the laptop I'm still queueing for is the PineBook[1].

I've never looked into tab grouping, because what I do, if my tabs start becoming unwieldy, is that I drag one of them out of the window, and it becomes a new window. I may drag other tabs into that new window if they belong together.

You people who use tab grouping, do you do this as well, giving you two-dimensional tab grouping, or does grouping replace multiple windows?

Interesting! I'd like to hear a little bit about the origins of the mixups when it is historically interesting... Like, perhaps, one word comes from French and the other from German. But not necessary, viewing Communication as the problem and English as a flawed tool to solve it is a good route to take. Looking forward to the next one.

Glad you liked the episode.
I'm amazed by the number of times I see the then/than and there/their/they're errors in forums, YouTube comments and similar. I don't know if it's an autocorrect problem or what it is, but it's very common.
I'm actively collecting similar problems, so I hope I'll have enough to make a few more episodes!

Thanks for starting that series!
While the first examples were quite obvious to me, I can see how they can be helpful on a global scope, given the diverse international HPR community.
Fort the last bit, I have to admit that those were actually two new words I learnt (make that three with "learnt" :-)).

Regards,
Michael

If you are interested, one of my _other_ favorite podcasts just did an episode on Social Security.

I just migrated from github to gitlab. So do a s/hub/lab/g in above links.

Great show and it sounds like a great way to delve into one of the mainstays of human life - sharing it and the world around us with those around us. Thanks Brian for giving all a way to connect and learn.

Nice to hear Slackware 32-bit still coming in useful. I don't mind that so many Linux distros are discarding 32-bit as long as somebody keeps it around, because while 32-bit hardware is fading, there's still a LOT of it out there.

Nice summery of the GDPR, Ken. I was wondering what this was all about. And I have noticed everyone and their brother sending out policy updates these days. But, as I doubt the GDPR pertains to my little servers I wasn't really paying much attention.

You did the deep dive for me. ;)

BTW, you might want to do Noise Reduction, then Truncate Silence. This one sounded a bit like a guy on radio keying up the mic at random times while talking. :P

How very appropriate that this would be released precisely for May 25th. :-)

I started participating in RPGs several months ago but did none of the things mentioned in this presentation prior to actually playing the game.

My GM took the small gathering of curious gamesters through a couple of relatively short scenarios/stories which kept the interest up and the mechanics of everything mentioned in this podcast at a double arm’s length away. We didn’t know it then but it kept us focused on the game rather than too many details of characters. Sure, we still built characters but it was a very abbreviated process. Not until some months and many game sessions later did I actually do my own research and discovered parts of what this podcast brings together very succinctly. And now that I know a bit more about the whole process, this podcast is all the more interesting.

Lostnbronx and Klaatu have done a splendid job of laying out a very understandable and approachable process for those curious about taking part in an RPG. (The sound production was stellar too.) Well done, gentlemen.

Yea, the Espeak kind of butchers my nick. I bet 'En Why Bill' would sound about right. Hey Espeak, I live in New York! ;)

Good luck your scope build. 25mhz will be right in the wheel house of the kit type scopes.

I too have a secret desire for an oscillascope. I'm building a wee one from a kit just now but that's mostly for fun. I'll need one that can handle 25MHz clock signals for troubleshooting my poorly Amiga 3000, hence my interest in this show.

Also, the HPR robot calls you nibble too! :D

This tickled all of my private places. Ok. just the references to free culture.

Loved the reader's voice. Liked the story.

I agree with pokey about the timing of things regarding can food, MREs et al. But it didn't keep me out of the story. I thought it was strange that people had forgotten so much in so few years. But I've some real life situations where people weren't taught anything for a generation and it is a bit like this.

I liked the 'glitches' these guys mentioned.

I can confirm that the issue with the ogg files is the album art. I didn't listen to this until after I listened to the audio book. I had the same issue. Downloaded fine but wouldn't play in rockbox. A little searching lead me to a suggestion that if an ogg file plays ok in vlc other other players but not rockbox, the album art is a likely culprit.

Removed them with Audio Tag Tool and all is well. If memory serves, the rockbox folks says it's because it only has 1mb for meta data.

Linux newbie here. I am working on a new project and last week, as a requisite, needed to install Git for Windows. I was wondering about the voodoo magic behind Git Bash, so thank you for the explanation.

By the way, cool alternate "beatbox" version of the HPR outro. :-)

First off, thanks for the mention, good sir! :-)

Secondly, thank you for this episode. As much as I use Cygwin at work, I despise...DESPISE...having to use the Cygwin Installer to install/update/remove packages. MSYS2 is what I've always wanted from Cygwin: an integrated, command line package manager for updating packages inside of the POSIX-compatible environment, just as you would do on any Unix-like system.

I'll have to start backing up my configuration files in order to make the big switch on my Windows PCs at work.

No butchering of "fractalide"! We pronounce it lile you do.

Now, "tertiary" and "tuturto" on the other hand ... ;-)

Your show was very quiet. I had to go 100% on the volume to understand you. I partly would blame the wind screen. Because, when you took it off, you got louder.

I misspoke, getting my POV names and distinctions mixed up a bit. I think I give enough examples in the episode to make it clear what I'm really talking about, though, and still stand by my observations about how they affect story construction.

Thanks for the correction!

What does the FLOSS landscape look like for fantasy games?

It occurred to me that from what I know about Chinese, in particular Cantonese, most of what you are saying about these nuances goes away.

You say that by just this little change in tense, you've already communicated something about the whole situation. In Chinese you can't really do that. If you try, you're making your text just unnatural and cumbersome to read. Must be a real challenge for translators in either direction.

From my personal conversations I also know that even pretty accomplished speakers coming from Chinese languages don't pick up on these cues when speaking English. All tense just goes through type erasure in parsing.

I think you might be a bit mistaken about 2nd person POV. My understanding is that it's not a distant pronoun (he or she)... that's still 3rd person. 2nd person is almost exclusively using "you" as the subject of the sentence for an action from the main character. So, useful in writing interactive stories... tougher for pure narrative.

Great episode about TLS 1.3! I just chuckled with the IETF comments about adding a decrypt function.

First of all, welcome to HPR. This is an excellent first episode!

Thank you for explaining the general problem solver. I haven't encountered this in my time as a programmer, and found the concept - and your introduction to it - to be very interesting.

I look forward to any other episodes you have planned!

While listening podcast about network design was interesting in itself, the soundscape of the episode is what sold me. It was like listening to Joy of Painting again with Bob Ross calmly explaining what he's about to do in such a friendly way.

Where is the wisdom from outer space when we need it the most?

I am indeed living the dream. I am working on cool software, it's all free software out in the open, and I'm getting paid.

Communicating what it is that Fractalide does is obviously something we need to work on. I know that when I saw it the first time two years ago I read the homepage at the time, and came away no wiser as to what was going on. Now I'm cursed with knowing what it is and no longer capable of experiencing what it is that a newcomer will need to now.

I heard you stumble over whether to call me "Ahuka" or just "Kevin". I believe that if I had to do it over again I would just use my name. When I joined it looked like people were using pseudonyms so I did as well, but it is not like I am hiding anything here.

To be clear, the HTML that had the divs in it was the asciidoc output, which I have just recently started using. The output from hashify.me has been nice and clean with no risk of having Ken pull his hairs out in frustration.

Our shared adventures with asciidoc, which played out in the comments, on the Fediverse and in private e-mail are fodder for a future episode on my new shownotes workflow. Yes, I owe you one.

If the question is, "can you do 3D modeling with OpenSCAD?", then the answer is yes. However, as I understand it, considering OpenSCAD an alternative to things like Fusion 360 and SolidWorks and others, is a bit tough. The open source world also has Blender, with which you can do 3D modeling too. But again, as I understand it, the way these options work is a lot different and they lack many of the features present in the commercial products.

It is worth mentioning that there are a few 3D modeling options out there that are not open source, but do work with Linux due to the fact that they are cloud/web based. OnShape.com comes to mind.

So, while there are alternatives, sort of, Fusion 360 seems to be becoming the software of choice in "Maker" circles.

I am a beginner at this, so these are mostly just my perceptions. Eventually, I may be able to speak with more authority, or at least more experience.

http://www.openscad.org/about.html

About OpenSCAD
OpenSCAD is software for creating solid 3D CAD models. It is free software and available for Linux/UNIX, Windows and Mac OS X. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.

OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designs that are defined by configurable parameters.

OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. Autocad DXF files can be used as the data exchange format for such 2D outlines. In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.

I neglected to name the author, because his name wasn't on my mind at the time.

Styx was written by Eric Sagnes, and if you look at his repositories on github[0], it's not really surprising that he would be the one to write a site generator in Nix. :-)

[0] https://github.com/ericsagnes?tab=repositories

It seems that when I countered that your setup didn't seem massively overengineered, I was simply insufficiently informed.

Now that this has been somewhat remedied, I agree with your assessment.

Thanks clacke,

I have used 'entr' in the past, actually to refresh my note-viewing browser when the notes change. I now use Qupzilla because it does that all by itself, which is very cool!

I will think about using 'entr' or 'watch' in future, but for HPR shownotes I have several 'make' targets, so I'm not sure if I want to automate them all.

For example I use 'make final' to generate notes with HPR links rather than the local ones I use while developing them, and I can only do that once I have chosen a slot and know what the HPR links will be. Of course, I could trigger the 'make final' once the slot has been selected.

Anyway, thanks for the idea :-)

I'm glad you enjoyed it. The project that I referred to in the episode didn't go quite as planned, but I'll give it another try at some point. Several other projects in the works as well. I'd be interested to hear about some of your projects.

I am an avid rocketeer and enjoyed listening to your show.

How have your future rocket projects been?

Doesn't sound terribly overengineered to me, it's just that my web editing workflow is minimalistic almost to a fault.

I have an engineered piece you can add to your solution: Trigger the builds automatically with entr[0]. That allows you to even skip the make step in vim. Just save and things happen.

Actually what I often do is I just `watch make` in the directory where I'm editing, or `while sleep 5; do make; done`.

Hi clacke,

A couple of interesting finds. I use both Markdown (Pandoc flavour mostly) and ASCIIDoc (via Asciidoctor).

I write all my HPR shownotes with Markdown, using Vim on one monitor and a browser on the other, building the output with Pandoc via Make, using Vim's 'make' interface to do it.

I also like to write a journal per project and use ASCIIDoc for that because I can generate much more interesting documents with colour, side notes, icons, good tables and so on. Again Vim lets me type the document with syntax highlighting, build it with 'make' and display it on my right-hand monitor using a dedicated browser (I like QupZilla at the moment).

My solution is probably massively over-engineered but I like it :-)

If you like ASCIIDoc, you can type your shownotes on https://asciidoclive.com/ and then do the same thing as I described above with hashify.me.

Just like hashify, asciidoclive allows you to type on the left, see the result on the right.

I pulled the name the_remora from Glenn Cook's Garrett PI series of novels. The Remora is a nickname of a tertiary character from the later books in the series.

Steve Saner gives a good tutorial on a way to add Windows to a Linux computer. I found the part about getting data from his old encrypted drive most interesting, as I have been a bit afraid of encrypting a drive for fear of finding myself locked out.

I am glad that he was able to use some information from my HPR show from last year on the subject of adding dual boot to my laptop.

Also, very good show notes for someone following his lead.

Enjoying the series. I am doing a tutorial on creating a LisP in C (which I heard about on HPR) and it uses Readline. So I came back to listen to this series. I always learn something. There's always an "Aha!" moment. Thanks!

When uploading the other shows I noticed that they had some weird clicks and jumps in them. Apparently I had turned on "skip silence" when I played with the settings. My recommendation is: don't.

Interesting "Space: The Next Trillion Dollar Industry"

https://www.youtube.com/watch?v=hiRBQxHrxNw

klaatu and Ken were discussing the merits on Markdown and the horribleness of the multitude of markdown flavors.

Here's what I do for shownotes: I write on hashify.me.

Markdown on the left, live rendered text on the right so you can easily Ctrl-click links to check them etc. Then I mark the text on the right, right-click and choose "View selection source" (this is on Firefox). It opens a new tab with the source almost correctly marked. I mark it, copy and then paste into the show notes textbox and choose HTML5 as text type.

Great podcast.

I've been using git for a few years now but there is something new even for a seasoned git user in this series.

It's a subject that needs clarity, because a lot of the online stuff about git is complex and confusing.

More please. And more about this kind of DevOps related stuff, and more server config and admin

I think China is our biggest chance for competition, in the long run, but they aren't moving quickly. That may change. I hope it does.

I also believe that the commercialization of space is the only real future it can possibly have. If people can't at least hope for a better life out there, they won't bother. China may be a big player here too, since it has no problem sponsoring large-scale commercial ventures.

Looked at from that point-of-view, though, business people like Musk and the others may turn out to be our last best hope for humanity, after all. I sure wouldn't mind being wrong!

Thanks Jan, Clinton Roy and clacke.

I'm glad you are finding the series useful.

I had known of Readline's existence for years, and that there were some features that might be useful, but had never spent the time to find out what it could do. I am most surprised at the amount of work that has gone into this library and the great features it offers.

I expect to be able to get another couple of shows from it before I'm finished, and there's scope for others to contribute too if they work out cool things to do with it!

Bought it, built it! Surprisingly straight forward, thanks a) to your advice nybill, and b) the link you couldn't get to worked first time for me had a pretty detailed picture guide.

"It's a bit clicky," says the wife, so all the more reason to use it.

So, here is a PG-13 picture of the calculator in action:

(I managed to break my GMG instance without even knowing about it! My next project, perhaps?)

Musk isn't the only one. He's the one who got the furthest, and who has the grandest master plan. But don't forget about Bezos and Branson and their space ventures.

So, I don't think we're pinning our hopes on one man. But my answer reveals something else. We're still pinning our hopes on Great Men (as in the Great Man theory of history). Musk, Bezos and Branson aren't geniuses in the sense that they are sciencing and engineering all this stuff when nobody else could, they're just hiring the people who do.

Still, I think people fawning over Musk is awesome, because it means people are pinning their hopes on research, engineering and entrepreneurship, because that's what he symbolizes. And hustling the money and funneling it in the right direction isn't nothing either.

It's far better than people admiring people who literally don't contribute anything, or are contributing negatively, to furthering the knowledge and power of the human race, like David Avocado Wolfe, Dr. Oz or Gwyneth Paltrow.

Ok, so we're not at the mercy at a single man, but we are at the mercy of three men? No. Don't forget about China and India, and old spacer-travelers Japan and ESA, and even Russia! They're also further into space than Bezos or Branson, and on some axes further than Musk.

I'm not overly worried. Humanity will get our eggs in a second basket before the century is over.

I warn about a few small pitfalls I ran into while building it. Hope it saves you the same trouble.

I haven't even listened to the episode yet, but I've just ordered myself one of those calculator kits from Amazon!

Correction to correction: No I didn't misspeak anything, we just misunderstood each other. Sorry for the confusion. :-)

This was an interesting discussion, maybe because of the disagreements?

Also, thank you for the audio notes.

I went into this thinking "bah, readline, it's C-r, C-a, C-e, some kill and yank, what's to learn?". But it was Dave, and somehow there was a Part 3, so maybe there were something useful in there?

Wow, I was so wrong about knowing everything there is to know about readline. I don't know how useful the capitalization things are, and C-t I already knew about and I think it's mostly useful for when you have pressed C-t by mistake ... but M-b and M-f, OMG.

I have needed these for years. I usually hop around with C-left and C-right, but when you're one mosh, one tmux and one su down, usually all arrow keycodes are long gone, and it's all misery. Now with M-b and M-f my life quality will drastically improve!

Also interesting to know what the args thing is for. I've been vaguely aware of it as it's easy to trigger by mistake, but I think I will use it more now that I have been taught exactly what it does. Maybe for counting the length of git commit messages, for example. You want a 60-character max commit message length? M-6 0 C-b after you typed your message will show you by how much you overran the limit!

Thanks, Dave. As always a great contribution, even for those of us who may think we already know everything.

Firstly, after hearing the title of this episode I thought you were going to be discussing how much three-dimensional space your thoughts took up. That's not something I've ever considered before.

Secondly, when you actually discussed the "loudness" of your own thoughts and what types of sounds successfully caused you to lose track of them, it was ALSO something I'd never considered.

Well done, Sir. Well done.

Hi Michael, many thanks for the comment, glad you enjoyed the show and your probably correct that a bit of commentary might have been a good idea. There was a couple of reasons that I chose not to add any commentary first it made the podcast easier to make but the real reason was that I was trying to create a bit of mystery for people that had never heard the strange sounds you'd find when tuning around the amateur radio HF band which I thought might be the case for a large portion of the audience.

When I was a young boy I remember listening to old second world war valved receivers that I occasionally had access to and was fascinated by the strange sounds and voices having no idea what I was listening to I thought initially giving no explanation would create more intrigue for those that had never heard HF before and if there interest was gripped then they could have a look for some show notes. I'll probably add some commentary next time if I do a similar show.

PS many thanks for deciphering the Morse code (CW), and yes that was some incredible set-up DF2BO had certainly beats my half wave dipole flung in the loft :)

Hi Dave I'm not surprised you didn't know about this as there are not many amateur radio rallies held in these parts I only know about it because I was a long time ago a member of the Cockenzie and Port Seton Amateur Radio Club. This event is a mini radio rally it originally went under the title of junk night but has since gone up market, it's held at Cockenzie & Port Seton Community Centre usually around the beginning of August, I've been going there for a number of years now best bit about it is meeting up with old friends and sampling some of the home made food. On the haul I usually end up with very little I just happened to be lucky this year.

I was not aware of the comment/decomment commands, they might be useful.

Hi Dave!

Thanks a lot for Your effort.

If a machine is under heavy load and therefor kind of not responsive anymore that readline-magic comes in handy. Same goes for a slow link between a users terminal and a remote machine.

Thanks Clinton, I'm really glad you enjoyed the episode. The last 10 years have really been a blast, and I can see many more podcasting years ahead!

I've had a few people call me "professional" and, whilst that isn't strictly true, I'd be lying if I said I wouldn't want to be!!

or a yard sale or a garage sale or maybe a ...

What a great story! I'm not into music podcasts at all really though (can't speed them up ;) but this was a fascinating look behind the scenes of a professional.

I do listen to a lot of podcasts, but one thing is that I speed them up by 70%, and the other is that I listen during many activities: driving, washing the dishes, going shopping, working out at the gym; they are all opportunities to listen.

I love the idea of tuning around and simply demonstrating what you can hear. However, I would suggest to add a bit more of commentary to make it more meaningful to those who not already know what they are listening to.

Let me add, that the morse code (CW) signal in both cases was a french station F5IN. Calling CQ DX, a general call for far away stations, in the first bit and just finishing a transmission in a contact in the second one.

When Tom, DF2BO, described his antenna set up, this left me mouth gaping. Yagis 2 elements on 80m (3.5Mhz) and 3 elements on 40m (7Mhz)! These are monsters, way beyond what any "normal" amateur will be able to put up. Just an amazing configuration, that almost makes me drool, when thinking about...
I think this is the kind of background information that makes sense to add, to put the audio in context.

Regards,
Michael

My question is, how many hours per day do you spend listening to podcasts? And are there that many hours in a day?

Thanks for the episodes. Quite the list.

Tricky bastards...

Thanks, I had not realize that I really don't need the gmail app.

Most of the time it was just annoying, I am almost always in front of a computer, so I would have find out about the new email a few seconds later. And for some reason the spell checker does not work if you updated it.

You have just freed me and my ram.

Will escape the | character !

The link to the Dutch book is http://duidelijkautistisch.nl/

I envy your finds! I didn't know there were such events in this part of the world.

Got word from Stewart (and he's https://twitter.com/sj_mackenzie btw , and Fractalide has an account at https://twitter.com/fractalide ) that I misspoke on something: A node won't have an info.rkt, it's one fractal, one package, and nodes are pointed out internally within that package.

For more on what all this means, what a fractal is and more, look forward to my interview with Stewart whenever we get that in order.

I hope you find the script useful. Suggestions for improvements and enhancements are welcome!

I hope you enjoy some of the channels I mentioned.

You could contribute some of your own recommendations at some point. I'm sure they'd be appreciated :-)

Alright, I made it a comment to spare you the work of correcting the original text and then you went and did it anyway. :-)

So I'll mail you the next time.

Oops, sorry I didn't notice the error when I processed your notes. I'll hand in my proof-reading badge...

I have fixed the error. Feel free to contact HPR admins via admin at hackerpublicradio.org if this sort of thing ever happens in the future.

Thanks Dave. I have a half dozen Pi's myself. This script will go directly into my script toolbox. Your mind is a treasure trove. Please keep digging!

Hi Klaatu, many thanks for the kind words, glad you found it enjoyable and sorry for taking so long to reply, I only just noticed the comment I really should check for comments more often.

Sitting in a train, listening to a podcast of someone in a train.

Congratulations! That is a milestone I can work towards.

I can't wait to look into these youtube pages. So many interesting subjects. Thanks!

The Toronto subway trains have steel wheels. The Montreal subway trains have rubber tires.

More details here - https://en.wikipedia.org/wiki/Rubber-tyred_metro

I recently moved to Atlanta, GA USA and it had been years since I used the local subway. Here they call it MARTA - Metropolitan Atlanta Rapid Transit Authority. It is a combination of subways and buses. This past weekend I decided to give MARTA a try. The Toronto subway sounds just like the Atlanta subway and no I didn't fall asleep. I rode the subway for three hours and only saw one person asleep.

Thanks for the tip! I am also very distract-able, and find myself rewinding HPR episodes constantly to catch what I just missed. I tried looping an episode (this one, in fact) and saw a real difference in what I remembered.

I was curious about the roosters, but didn't mind them too much. Perhaps just list them as a co-host next time? ;)

Quite a topic for a first episode!

I enjoyed it, and look forward to your next submission. :)

It's been many a year since I was in Canada: are these the rubber wheeled ones?

I would just like to publicly say thank you to the admins to fixed my mistake, in a way that will force them to read it aloud ;)

1. Yes you describe why I hate forums.
2. Why did you not record a show describing the peoblem? I know several hosts that have ffmpeg foo. We have the exact same needs for hpr itself

I've somehow managed to upload both interviews in the one show :(

I haven't even edited the second interview yet.

I really enjoyed this installment of the Audiobook Club. It was great hearing from the author, who was thoughtful and articulate, explaining what sounded like complex concepts and making them clear. I'm really excited to listen to this book, spoilers notwithstanding.

Great job, guys!

I meant to remove the roosters but forgot. In the Philippines and there are roosters everywhere.

As soon as you said Star Trek, it made me think of TNG season 7, an episode called Masks . In that episode both Data and Picard wore masks and had altered roles.

Just wanted to say thanks to operat0r for bringing tron-script to my attention. I hate maintaining the windows boxes at work (5 windows boxes and 7 linux boxes). I have run tron-script on 3 of the machines so far and they are running a LOT quicker now including one of the win7 machines which got stuck installing updates a while back and even after hours of searching for a solution to the problem, nothing. Tron-script has resolved the issue and the machine is now up to date :)
It looks like tron-script has been around for quite some time and has remained under my radar. So thanks again for the episode and bringing it to my attention.
I wonder what other tools HPR listeners use that I or others have not heard of?

The repeal of the Individual Mandate was covered in this last episode, I believe.

Does the removal of the individual mandate justify an update?

I meant to say that when I'm walking around I prefer to listen sped up not normal speed.

Excellent discussion.

One fact I would contribute is that women throughout most of history have been treated as property. Much of what you all said about the status of women before prohibition was reflective of this. I'm old and I can remember when, in the USA, a woman could not get a loan, a mortgage, or a credit card without a male cosigner, if she could get one at all.

And, as we can see from current history, many men still view women as property, indeed, as playthings.

In addition, as a lifelong reader of Playboy (and at the risk of starting something), I must, with some trepidation, question how Playboy pictures can be conflated with pornography, unless the conflator believes that nudity is inherently pornographic, a position I do not share. I would argue that said person, at the least, has never seen a copy of Hustler. nor an image of the Venus de Milo.

Why for that matter, do you think the great masters of painting have painted so many nudes? I guarantee--as Justin Wilson used to say--it wasn't solely because of an abstract appreciation of color and form.

Once more, an excellent discussion.

I've enjoyed every episode of this series, and find your explanations of the concepts behind these policies invaluable.

With so much rhetoric and propaganda surrounding the healthcare debate, a factual explanation is just what I needed to hear.

Thank you so much!

How did I miss this from Hasbro Interactive? Cool.

As for making a new console which will play the old cartridges, I don't think that would be economically feasible and doubt many would buy them. In my experience people who want to play on real hardware, want the actual hardware.

Perhaps this will change as more and more old systems die out. In the case of the 2600, while I lost countless hours of my youth to it, there are only a handful of 2600 games worth playing.

I don't see any major player creating such a system. Perhaps a small, expensive runs, which would make most people use emulators on machines they already have.

Loved listening to this series. As someone who wishes they had more free time to get into Pathfinder/D&D/etc. (picked up the Pathfinder Beginners Box, but currently it's collecting dust bunnies) I hope this idea/series continues!

jif will always be a micro liquid...

Do you plan to continue recording more of these? I hope so!

This sounds like one those long-tail tools that you never knew how much you needed, until you came across them. I have a few like that (and that's one of the topics I have in my 'one day when I make a HPR recording' ideas), ShareX might go in that list if it works on my potato of a laptop.

(But making an informative, quality podcast episode doesn't excuse your proud mispronunciation of 'gif', Xoke. Please repent by sharing ten gifs of adorable kittens/puppies online.)

I am a fanatic about the Lensman series. In fact, my e-mail address comes from that series.

Yes, maybe I should have provided an easy-to-download temporary version of the game, plus the full rules. Thanks for the idea. If I try again, maybe that's something I'll try.

Qapla'!

The last time I heard an audio performance this good was at the Yes concert in Denver. Sadly, the band couldn't make it but the opening act was pretty great.

Thank you for these two episodes (2446 & 2461)!

I have been using git at work for over 5-1/2 years on two desktops and one laptop (1 Windows XP and 2 Linux) using ssh keys that I have manually put in place on the various machines.

I currently have over 60 unique repositories of which some are customer configuration specific and some are globally common.

At this point in time, I need to allow access for other developers to "my" repos. It took me around a day to implement the method explained in episode 2446 and less than a couple of hours to replace that with using gitolite! Managing the keys and wildcard repos within gitolite is so much easier than the manual requirements of the method from episode 2446.

I also had problems with MobileOrg, but found another solution. I have an owncloud instance where my orgmode directory is mirrored. On the android device I have installed the owncloud client-app and orgzly. Orgzly is syncing to the local owncloud org directory and the owncloud client is then syncing with the server. It sound harder than it is in RL.

I somehow missed this comment until the monthly show read it aloud.

Agreed, Frank. yum (and dnf, now) really is a great interface to packages. I have found zypper in openSUSE to be pretty neat, too.

Hi Brian -

Thanks for your feedback!

As far as I know, we’re not being or striving to be anything funnier or smarter or longer or Kickstarter-supported than being the Alien Brothers Podcast hosted on Hacker Public Radio, at their consider help, support and bandwidth/space largess.

Our over-used phrased is this is the Alien Brothers Podcast, and not some other one.

If we’re “terrible”, we invite a lucid critique because, I mean, we already know we’re terrible. It’s the Alien Brothers Podcast. I can only assume by your use of that single word you mean “tremendous” as in “Oz the Great and Terrible”.

Casper and I have had conversations acknowledging our segments are too long.

Keep coming back! -r
[1] although I believe length is important is certain contexts, but I know Casper and I are conscious of the fact our submissions are almost certainly too long
