Absolutely please use https://github.com/stevesaner/pi-sdcard-setup script.

Since posting this show, there has been a follow up episode
http://hackerpublicradio.org/eps.php?id=3173

The script mentioned here is now been maintained on github at
https://github.com/kenfallon/fix-ssh-on-pi

Do yourself a favor and run this guys fork of the script...
https://github.com/stevesaner/pi-sdcard-setup

It removes some of the checksum complexities and other things that confuse the original setup.

Great episode and lots of good management tools through this approach.

Enjoyed this episode which I began listening to and then switched over to the video version.

I used dwm as my main desktop many years ago, perhaps 8 or so, and it brought my rather underpowered laptop alive. In the end I abandoned dwm because I had to use netbeans everyday and for reasons I never understood it wouldn't work with dwm. I'm back with KDE again for now - yes, I like extremes! - but you've nudged me into giving down another whirl.

Hi Clacke,

What I couldn't recall at the time was the name Berkely DB. I used this for a while when it was owned by a company called Sleepycat. Later it was bought by Oracle.

We were OpenLDAP users at the university I worked at, and this ran on top of Berkely DB files. I failed to remember all of this in the show itself of course :-)

Hearing Your linux journey was like hearing someone read mine aloud. Though, my journey started a few years before yours. The win98/ME migration was my nudge to look into alternate operating systems. Like you, most of the communities I have encountered have been very friendly and helpful, I've not delved into the ARCH world, but have encountered that type attitude elsewhere. Eletism exists everywhere, how we react to it is up to us.

That aside, welcome to one of the best communities on the web.

Most people pronounce it /reddis/, not /reedis/.

It is often used as a cache to avoid expensive database lookups, much like one would use e.g. memcache, and I've always interpreted the name to hint at "I don't need to make that heavy multiple-tables join, because I know I already 'read this' just a moment ago".

I've never looked up what the official story of the name is.

Dave said "this preceded NoSQL I imagine", and he was referring to key/value stores in general I believe, which are indeed older than relational databases and are a layer on top of which relational databases are built.

When I initially heard it, I thought it referred to Redis specifically, and I thought "no way, Redis came out in the middle of the NoSQL boom".

I was wrong, by two days. :-D

Redis came out on 2009-05-10 and the term NoSQL in the current sense was coined on 2009-05-12.

Knowing how difficult it can be to engage a small child in front of a microphone without them going all shy, or grabbing hold of it and making farting noises, this was amazing to listen to! Thanks for the entertainment!

I think the main reason you don't see People of Color (POC) in the floss community is the same reason you don't see lots of black folks in lots of other industries. POC have been purposefully kept out of tech jobs in America! It's the same reason you don't see women in many of these places as well.
I would postulate that 'many' of the people who contribute to Floss also work in tech in some way or another. (Notice the word 'many'...not 'all' or 'most')

Just so you know... I'm black man, US citizen who lives in New York
City. I work as a software engineer and I'm also interested in Floss.

blizzack.com

I enjoy hearing stories about (African) American experiences like this. There was...as you mentioned a 'Great Black Migration' that happened in the States. It sounds as though you've done quite well for yourself and you have a strong community around that cares about you getting ahead in life. That's awesome and we all need something like this in our lives.

Thanks for sharing your back story about you and your family. I do appreciate someone talking about something else other their newest laptop, or the latest distro of their favorite operating system.

This is a podcast and like most podcasts there's lots of rambling and lots of pundits.

I think you are making some broad generalizations about People Of Color (POC) in America -- even though you are a member of that community. I know you stated - this is from your experience.

For instance, you state you feel the reason that POC are not vocal in the Floss community is because they're somehow afraid. I don't believe this at all.

I think many POC are unaware of many FLOSS technological tools...but so are lots of other people who are not black, brown, or women. Being ignorant or unaware of something does NOT make you afraid !

I'm sure your family was apprehensive of being part of that Great Migration; but they did it! So did millions of other African Americans. https://en.wikipedia.org/wiki/Great_Migration_%28African_American%29

POC consume a lot of technical information just like any other folks in America. They use computers, cell phones tablets...etc. Additionally, they spend lots of money on tech related items.
Tech companies want POC communities (all communities for that matter) to consume their products. They have no interest in these communities participating in its implementation.

For instance, Are we to believe that Apple couldn't hire a POC as part of their QA team for their watches ??

...I'll have my agent contact you. ;-)

I'm currently battling with split-horizon DNS and DHCP on my local LAN, using a PiHole and the underlying dnsmasq server.

I'm very happy to have this episode as a "Plan B"; it's a very clever way to roll your own network services without having to worry about manual configs and fragile setups.

Thanks for the great episode!

I thought this show was very timely, and I would welcome further discussion. Freed software and open technology create possibilities, but they aren't guaranteed if people don't take the necessary actions.

I agree with norist, swift110 is quite the story-teller.

I could tell you were a man of taste when i saw the ThinkPad on your prior eps listing. T420 is a great Linux platform! (Especially sweet if bought refurb. :-D )

(FWIW, Wikipedia says Langston Terraces were second federally funded projects in the nation.)

You're asking good questions.

One of the newest housing projects in Boston has a Technology Center within the campus, co-sponsored by MIT. southendtechcenter.org
When Ubuntu LoCo teams were dis-established, some of the core volunteers here moved there.

Thank you, swift110 , for the episode. You have a gift for storytelling, and I hope you continue. This is an important issue. I don't know how to help except to promote stories like this. I look forward to hearing from swift110 again.

Yes, Ken, the show name was somewhat intentional. This was only after I saw your future show on the Internet Archive while I was preparing show notes, and thought it would be a nice play on words.

I have yet to crack a screen on any of my devices (knock on wood), but hearing the story of your IPad made me wince as if I had.

As a silver lining, it made a very enjoyable episode. Thanks!

"I had been using systemctl restart apache2.service to restart apache, but the recommended way is to use apache2ctl."

Interesting observation, as the only difference seems to be a PrivateTmp clause in the unit definition of the service.

I wonder why exactly that made a difference indeed...

Great show, and I am promoting it on my social media.

Hi Swift. Really enjoyed your show.

If you look at the representation of the black community in the wider community of Linux/FLOSS then I think you are definitely on to something. However, there are a great number of non-white contributors to FLOSS projects all over the world - particularly on the Indian sub-continent. It would, I think, be a shame if anybody new to Linux and FLOSS felt there may be any kind of bias against, or any favour of, any racial group - not that I think you were suggesting that there is.

Because communication between contributors on projects often takes place using text-based messaging, for the most part we probably have no idea what the people we correspond with look like, or are like as people. Everyone is as good as their contributions, which is just as it should be.

You made the point that if you had not told the listeners of your racial background nobody would likely have known from your voice or accent. Absolutely right, so it's entirely possible that could be the case with a number of other HPR contributors.

Women, though, have far more distinctive voices so I think it's indisputable that of 3000+ HPR shows, the number submitted by women is pitiful. Diversity takes many forms, so I think there is at least as big an issue with gender diversity in Linux/FLOSS as there is in ethnicity.

To think in terms of a diversity "problem" hints at there being conscious efforts to attract or exclude certain groups. I honestly don't think that is the case in the Linux/FLOSS world, but there can be no doubt that broadening its appeal as widely as possible across society can only bring benefits at every level.

Hi Swift, I just wanted to say thank you for your show it is always good to hear things from the perspective of the a person who 'any' community finds hard to reach.

I know this is not a simple issue and there are many reasons why different community's do not mix, but hearing your experience and thoughts on the issue was very refreshing.

Thank you for a very thoughtful episode.

Tony Hughes

Don't worry. You're not the only black host in HPR! I've got plenty of stories just like yours. I can relate to your experiences.

Wow! I'm enormously impressed by Freedom Internet. This is how businesses should be run! Thanks for this great interview.

Greetings and great show! yall rock! Now we got kernals that are like a terabyte...ohhh you need something? yah man just turn all these kernal mods on ... everything is fine...

I just discovered nethogs in linux. Along with tmux zi have a dashboard that shows GPU / CPU / Network stats/pids



# tmux 3 pane failsause
pkill -f tmux
tmux new-session -s asdf -n myWindow -d 'bashtop';
split-window -d 'nethogs -v 3';
split-window -d 'intel_gpu_top';
select-pane -t 0 ;
resize-pane -y 24 ; attach-session

I've been using Pandas and Numpy for years, and didn't know about np.select (from your code example). That's definitely going to come in handy.

I suspect b-yeezi has some serious scientific training because he does a good job on this. A common misconception Ihave heard form soe people is that the MRNA vaccines might change DNA. And it just doesn't work that way. DNA is what produces RNA, not the other way around.

It is always good to hear from a new host, and I love the routine he has.

THis was a great show. I hope to hear more.

There was the Blog and then the Podcasts. Soon after VBlogs (Videoblogs) came up. While a podcast is/was to me a conversation between two or more people, the content on HPR is to me 96% more like an A-Blog (Audioblog).
While hearing Ken & Dave asking for more content, I would like to do that, but do I want to do a Podcast or an A-Blog?

So, although they were not speaking with eachother, I liked the concept and content.

As if a masterclass on AWK wasn't enough, now he gives us a detailed explanation of PCR testing.

Thank you for this episode. It was incredibly interesting.

I wish I had an ISP as good as that where I am.

Really useful and educational episode. It's easy to not think about vulnerabilities, but it's so important to keep updated on the ones that are out there, and to learn from trends. Thanks for this reminder.

Jack can work with Pulseaudio, I use it by default.

The Ubuntu Studio provides all the required configurations and tools to use Jack with Pulseaudio, along with a low-latency kernel.

I'm not waiting for Pipewire...

Fabulous show, and interesting concept of using Klaatu's show and adding to it. It was so interesting I am working on my own follow-up to add to the conversation.

I would love to hear more about the online video editing he was talking about. My own experiences with kdenlive have not been that good, for whatever reason.

I am impressed by your Chromebook skills. Teach me your ways.

Do you have a link to the Video referenced.

Hi Jon,
It has been a while since any development work has been done on Blather. The codebase was ported to newer versions of Python, Gtk, Qt, and Pocketsphinx in 2017. Unfortunately, it would appear that every Linux distro is missing *something* that is required for the "new" version, and my primary Blather machine (Debian 11) still runs the old version of Blather with all of the old libraries installed. It is a depressing situation. harumph

This technique seems like a great way to allow my loved ones to have an emergency "skeleton key" for all of my computers... in case that hypothetical "bus" ever shows up.

Thanks so much for the tip!

Thank you for this information, it is getting me thinking. I have an account on a Web hosting service, and it sounds like maybe I could install an instance there. But I wonder if I should create separate domain for that. My sites run WordPress and of course have MySQL databases for that, but can you have both a WordPress site and a NextCloud instance on a single database?

Hi Klaatu,

I have used the UI for upgrading

> Profile Icon
> Settings
> Administration
> Overview Upgrade

Is there any reason not do do that ?

this is very nice

I will definitely do a show on PCR.

Also, I agree with you that open standards and decentralization are good things. However, without the open standards and a cohesive, unified plan, decentralization leads to all the problems I've described here.

Great show!

I have tinkered with taskwarrior for years but never used it in earnest. It's been around for quite a while, and has developed a lot in its lifetime, but I have never quite found that it could do what I wanted. I think this is partly because you have to explore every nook and cranny of what it offers before its usefulness becomes clear - or maybe I mean *I* have to do this!

I have always found its documentation to be a bit difficult to penetrate, because of the way it's laid out, and I haven't persisted. I mainly use the task capabilities of Thunderbird to remind me what I should be doing. However, I'd like to master taskwarrior and look forward to reading your book about it ;-)

This was a great episode, and I really like the tool. I downloaded and tried it out and it works just as advertised. I don't think I will be using this as my primary ToDo list since it would require me to be sitting at a terminal to access it, but I'm glad to know about it. I mostly use MyTinyToDo list (see hpr1899 :: MyTinyTodo List), which I have installed on my virtual private server and can access from any web browser. I also use the Tasks application on Office365 for certain tasks at work, since that's the platform our University uses. I definitely find taskwarrior appealing, though, and I'm amazed at the robust feature set. Thanks for this introduction.

Great episode! I really enjoyed it but there's a major component missing. PICTURES of your fish and tanks! I kept wanting to see these. Looking forward to follow-ups.

Good to hear from you. I appreciated the show. Thanks for your insight. Could you do a show on the mechanics of the PCR test? Also, I hope this show doesn't lead people to think centralized controlled governments are the solution to any problem. Open standards, decentralization, liberty and freedom for ALL!

Hi Ray,

Thanks for the feedback. HPR is a Audio only Podcast, but I think Paul did a great job of describing the tool. I was able to follow along without problem while out and about.

If you are interested in helping out, feel free to record a screen cast of the steps Paul took with this show as the audio track. We will happily link it here, or if you release it under a Creative Commons License we can add it to the episode.

Ken.

When talking about GUIs it would have been a lot more useful to have a video podcast instead. Seeing it in action would then have been possible.

I'm glad you enjoyed it, and please do check it out. I am finding the Fediverse very congenial.

Thanks for your shows about the Fediverse. I think I'm going to have to check it out.

Great eps last time I talked to any of thos folks was years ago. I think I ran into droops 5+ years ago. We used to have a local group that met up at "Frys Electronics" called hackatl or something. I'm waiting to start up local meetup here in Roswell GA

I am enjoying Paul Quirk's shows, and I'm looking forward to more. Darktable sounds like an interesting application that I need to check out.

Thanks for a wonderful episode. It amazes me that there are actual people out there having this as their job. It seems like a dream come true, to me. Here I am unemployed atm, trying to scrape by. This surely puts one's life into perspective. lol.

hey, operat0r just wanted to let you know that this is probably my absolute favorite hpr episode to date. very good! made me want to get more into networking. thanks and keep up the good work!

I thought this was a great show. I look forward to more.

I hope you do more about work in the electrical trades.
Maybe some details about getting into the industry and what apprenticeships are like.

Dave - thank you for looking that up. Dividing surprises me actually as I was thinking it was more to do with movement but lines divide a 2D space and great circles divide a sphere so it makes sense.

sesamemucho - glad it was helpful. "On a tangent..." is a very apt choice of words!

Gday Paul
I emailed you a feedback responce

Great interview with Frank Karlitschek. I'd love to know more about Next Cloud.

Proving I have totally lost my memory

Ahhh finally - the whole piece of the puzzle !

I *knew* someone did a show about this. I should have guessed.

Thanks for this episode Klaatu.

There were some good things in there to think about. Bit of a pity you didn't use the 'theatre of the mind' phrase to emphasise the way DMs and players can enhance their enjoyment by graphic and detailed description. But I guess it is a bit of a cliche.

I will think about responding to this show with one of my own, and what I have done on the way to taking up D&D again after over forty years of not playing since I was at school.

One term I had never heard until this show is 'dice tower'. Now I think you might have caused a few more quid to leave my bank and end up in Jeff Bezos'. Even though I can't see the dice I have been unable to resist buying lots of them recently.

On listening to the 'Critical Role' podcast, I fell in love with the sound of what sounded like a wooden dice tray.

Typing 'roll d20' at a Linux prompt is useful, but lacks soul.

Enjoyed your first show, always knew i wanted to be a vampire.

Electricity can kill you and burn down your house. Before doing any
electrical work, please be sure to follow all local codes and safety
procedures according to the authority that has jurisdiction in your
area.

I think Brian has the right idea. A show, or maybe several, on darktable would be awesome!

Wow, sounds like a great idea for a show!

What did you find works best for the compression settings? Did you use standard setting, or find tweaks that would best suit your setup?

Great show. Have you considered doing a series on Darktable? It would dovetail nicely with the GIMP series.

https://cheatography.com/davechild/cheat-sheets/ubuntu-compose-key-combinations/pdf_bw/

I found this quite interesting, I've never even thought about such requirements; thank you.

Hey man, I love this show each and everytime. The mood is great and the content is very much interesting. I love listening to people talking about interesting things in a relaxed context and this show pulls that perfectly. Keep them comming

Great show. Coincidently I had heard a show on the same topic on national radio here in Belgium. Their angle was how the Spanish Flue had actually ended the first world war, and that most of the casualties in that conflict originated from that desease instead of the fighting.

Hey Ken, loved the episode. I also like walking around on grave yards, they combine the best in of three key factors I think:
1) Silence. There are a lot of loud places these days but a graveyard is almost everywhere a place of serenity.
2) Art. I don't know how things are over there but here a lot of graves are real works of art.
3) History. Even the grave yard of a small little town tells dozens of stories.

Visiting tips in Europe from a fellow grave yard lover:
- Père Lachaise Cemetery in Paris, FR
- Schoonselhof in Antwerp, BE

Hi Norrist,
I have just recently started using Ansible. I'm currently playing with my new toy, a Turing Pi board equiped with 7 Raspberry Pi Compute modules, basically it's like a single board cluster so to speak :-) Anyways, I found Ansible extremely helpfull in setting these up.
First I made sure all Pi's had a fresh install of Ubuntu server with Ssh enabled and an account that authorized my public key. Then I just created a simple inventory file with the IPs of each node and I was good to go. Then I could just do:
ansible -c cluster -a "sudo apt update && sudo apt install -y kubernetes"

Thank you for this show. I found it very interesting to hear how another country/county is dealing with this virus from an individual's perspective. We often hear that Sweden is dealing with COVID-19 by requiring much lighter restrictions than where I am in Scotland/UK but your description doesn't sound very different from the situation here. One notable difference is that you said older children are not all back at school. Here *all* children are back but due to an outbreak at his school my son is currently at home self isolating as are most of his year group (15-16 year olds) of 100 or so pupils. This should not have come as a surprise as I understand that the virus spreads amongst older children much like it does with adults, though the disease is much less severe in most cases.

I knew this had to be on the Internet somewhere.

Good show. but I'm a bit confused, people tell me there are to many people on planet earth, to much man made global climate change. Isn't disease a good thing? Doesn't it thin the herd? What should I be afraid of today? Too many people? Too much C02? Capatalism?

It's almost like the separate streams were spliced on top of each other, rather than interleaved?

The Fedora Wiki page (https://fedoraproject.org/wiki/Contribute) explains that they are not looking for money, which I suspect is because they have strong corporate support. I would guess Ubuntu is much the same. But there is more than one way to support a project you like. How about doing some shows on Fedora, why you like it, how to configure it, and so on.

Thanks for the show and the Patreon link. I would like to give a little to some projects too, but sometimes it is a bit tricky to find a way to regularly donate. For example, I started using Fedora, and so does my wife, but could not even find a one time donation button.

Thanks for your show. I really enjoy make mkv. unfortunately, I have had better luck with it on my windows partition, there are more restrictions ripping DVDs when I use my ubuntu laptop. Since my home has limited broadband, I like to buy DVDs and rip them on my computer to watch off line. I use handbrake to compress the video files. So, you're not the only one who uses make mkv!

Interestingly, although I can't see, I don't find the indentation in YAML as annoying or as difficult as Python. And:

pip3 install ansible-lint

Will give you a good linter for Ansible YAML.

I have a repository on github:

github.com.cromarty/ansible-raspberry-pi

With loads of roles and playbooks, mostly with an a11y bent.

I think I might do a show about. I love writing Ansible and I'm good at it, although I say it myself.

While I am here...espeak rules OK? :-)

When typing in Spanish or French, I've long used the Compose key in X. In my startup script (~/.xinit, ~/.xsession, or for me as a fluxbox user, ~/.fluxbox/startup) I have the following line

setxkbmap -option compose:caps

which turns my Caps key (which I never otherwise use) into a Compose key (here are ways to use other keys instead, if you prefer).

I can then type "{compose}{e}{'}" to get "é" or I type "{compose}{n}{~}" to get "ñ" or "{compose}{c}{,}" to get "ç". Similarly I can use "{compose}{?}{?}" and "{compose}{!}{!}" to get "¿" and "¡". There are hundreds of these composable characters and many are intuitive enough that I can guess them if I don't know them cold.

Should work out of the box on Linux & BSD systems running X, and work with pretty much every X application.

Aaron, Zen_Floater2,

Glad you are enjoying HPR and our chit-chat shows.They are quite fun to do, and we'll probably make more when we can.

Hi Ahuka,

Yes, I was very sad to see the trend away from San Disk Sansa players that could run Rockbox, and then their disappearance. I did manage to buy some new, refurbished and second-hand players before prices became ridiculous, and have survived on them for many years. When they have all stopped working I don't know what I'll do!

A second disk is not an absolute requirement if you are already using ZFS on root. I made the recommendation for a second disk because some VPS providers still default to UFS for the root partition.

Thanks to 0xf10e for the feedback

Hi norrist,

why do you recommend a 2nd disk with
a new pool to use for iocage? Using
iocage on the host's root(fs) pool
works just fine. If I had spare disk
(or even cheap storage for a VPS) I
would rather use it to mirror my
system including the iocage dataset.

Regards, 0xf10e

My favorite combo was the Sansa Clip Plus with Rockbox. Sadly, San Disk stopped making them

Hi Reto,

I have found that if the players lock up in some way a very long press on the on/off button can reset them. Worth a try anyway.

Installing Rockbox is not difficult. All you need to do is download the installer (https://www.rockbox.org/download/) and follow the instructions on the site. It's years since I have done it but I remember that it was very straightforward at the time. You don't need to dismantle the player in any way.

I found the original SanDisk software was very poor but Rockbox has provided all the features I need for many years.

Dave

I especially enjoy local chit-chat conversations. There really should be more shows like these.

I have only recently discovered HPR and I'm enjoying the variety of topics and hosts - thanks for the great resource!

Hi Dave,

Just like you I have Sansa MP3 Players (Clip Sport & Clip Zip). These are awesome, something like 48 g, play several hours and if you treat them well last several years. Mine is now 6 years old.
OGG is not their strenght, but can play most files. For this reason I always subscribe to MP3.
I also like at least basic ID3-tags. The 'Album' is an important tag and only ID3v2 works well on Sansa's firmware.

Unfortunately, the Zip at someday got stuck at "refreshing your media". I read you could open it and flash Rockbox or try to access via serial, but the housing is very thight, almost zero gap.

I plan to listen to your Rockbox flash podcast :)

Cheers
Reto

Hi Dave,

Thank you for this podcast. A nice knife is like a nice fountain pen. Way too little chances to use it while it is such a nice product.

Thanks to your hint I listened to the podcast about OPINEL and it reminded me about mine, somewhere in a box, I was disappointed that it was'nt stainless steel. I dug it out and learned that carbon steel is harder and can get a patina similar to other metall.

Now, I like this rusty knive, because I understand :)

Cheers
Reto

Thanks for the overview of Nextcloud - I run my own instance, and half of the apps you mentioned were news to me. It's become an essential part of my network, and I'm still finding more uses for it!

I loved this show, and I hope he does more "war stories" for us!

Hi Cedric. This is a fascinating episode.

It seems amazing that a company which is sufficiently concerned about security to hire a pen testing team did not have procedures in place to ensure the access control system server was protected with something better than admin/admin.

My guess is that they did have such procedures but that they were insufficiently monitored. You can have the tightest standards and procedures in the world, but if there is no checking for compliance they are worthless.

The only thing I would do is to put a beep or something between the segments.

I had a Vic 20 once and wrote in basic and assembler on that machine. I thought the tape recorder was too expensive so I made my own out of a panasonic tape recorder and a bread board I put together.
I wrote llog book programs, Amtor programs and Continental Code trainers on the Vic 20. It was a fun machine and very fast too.

Another great episode!

But... Martin, for the love of christ, will you please SPEAK UP?!?!

You're always so quiet and mumbly I can't hear you unless I turn my volume way up. Then Chris comes back on and blows out my eardrums until I turn it back down.

Perhaps you could each record on separate audio channels, and then equalize the volume in post-production?

Thanks for the show, keep up the good work!

Thanks for this episode. I write software in the medical field all the time. It's good to see that the best practices that I've been taught are actually correct.

I would love another episode like this!

Regarding the 6 foot distance of separation, I should have been clearer that this is a recommendation for when you are out-of-doors. There is no such things as a safe distance if you are indoors with someone who has the disease. If you are there for long you will get the disease.

I wasn't looking for sympathy, I was hoping you would see that falling into using pejorative statements is exactly the cause of so many problems between people. Using the word stupid stops the conversation, that was my point.

The intro voice for that show was the best. How was it done?

The UK did in lower their records by 5,000. However the reason was not bad record keeping as claimed above. In England the tally included anyone who has tested positive for COVID-19 and later died, with no cut-off point between positive test and death. While Scotland only counts deaths that occur within 28 days of a positive test.

Their official statement is here:
https://publichealthmatters.blog.gov.uk/2020/08/12/behind-the-headlines-counting-COVID-19-deaths/

Classifications should be done as follows:

"A death due to COVID-19 is defined for surveillance purposes as a death resulting from a clinically compatible illness, in a probable or confirmed COVID-19 case, unless there is a clear alternative cause of death that cannot be related to COVID disease (e.g. trauma)."

https://www.who.int/classifications/icd/Guidelines_Cause_of_Death_COVID-19.pdf

Too bad that everyone who isn’t as brainwashed as you is stupid. This is clearly overhyped and playing on people’s fears for financial gain. When my uncle died due to a pacemaker failure and the hospital listed coronavirus in order to collect their check, this became obvious. But hey, what do I know. I’m probably stupid...

These guys missed a great opportunity, the art of the followw up question is dead. When Randll said it was on the blog why he got fired by leo, they should have asked, "for those who don't follow the twit blog, could you recap the events that led to your being shown the door at twit?" Here's the blog post link, https://twit.tv/posts/inside-twit/doc-searls-new-host-floss-weekly, its useless. Leo's terrible twit is dead long live monsterb and TiT radio!

Fantastic interview with Randal. I also thought the FLOSS Weekly transition was rather abrupt and also wondered what happened. I also had no idea there was anything on their blog, especially after having conducted web searches right after it happened. Great to hear from him again and the things he's working on going forward.

It seems I've gotten the MOST comments on my shows of anyone here in HPR in quite a long time. At first, they came after me for my show notes. When that didn't work, they switched to attacking my tiitles. I ignored that as well. Finally, they are referencing me on OTHER people's shows now. HPR3137 - Ahuka has a comment from one of his viewers and he's addressed it to me, Zen_Floater2. And as a Squirrel who lives in a Magical forrest, I pondered, how should I address this human being??? Why would he ask me about what I thought about Ahuka's show? Ahuka got only one negative comment on his show and Ahuka called the people who didn't follow his narrative stupid idiots I'm guessing from the commentary. Study my work Ahuka and you will get more negative comments over time. I'm a firm believer that if you do, you too can have most of the HPR audience out for your blood. And I've never understood why humans would care about other humans not taking some vaccine. It clearly makes no sense and forces me to climb up a tree sometimes to get awy from Humans. Thank you everyone

I have a stock, from the factor Dell Mini 10. Never opened it up.
1 GB of memory Intel Atom N450 cpu and 250 GB Hard Drive. The Hard drive is so old, it shows up as wd0!!! But, when I run Fuguita 386 on it, it shows up as sd0, go figure. OpenBSD supports AMD64 variants of their OS will all the Intel DRM. I'm running the 386 version of OpenBSD and I"m afraid I really don't know if this notebooks FredFlintstoneLake Intel Graphics is actually supported on the 386 version. Things are slow but not horrible on this laptop. I still have the original WIFI chip in this notebook and mine is Atheros. Dell has been known to switch out hardware on production lines -mid-stream- for all their computers so it doesn't surprise me one bit you had a different WIFI from mine. I've still got the Original factory battery also. The Dell Mini 10 is fanless and quiet. OpenBSD doesn't PUSH the hardware into overheating. I need to look into expanding my memory, if that's even possible on this model as it was the very first of the Dell Mini 10 series, the first year they offered the Mini 10 Inspiron. I've always been told the ram is soldered in on this model and that I was screwed but, I need to open this up and look around. Maybe at least upgrade my hard drive also and put some fresh CPU paste on the heat sink. It's over 12 years old now. Still very reliable, and I use it very day. I'm using it now to type your message. Take care and bye..

I must agree with you that Covid-19 has proven to cause damage to heart, lungs, and livers and kidneys and even brain damage.

I think the part that I didn't understand was your comment about watching some video's that you admit Doctors would not endorse or watch...

Clearly, the medical community is divided on all this stuff. The half which is not siding with the WHO have been banned from Twitter and Facebook and have had their video's taken off of Youtube, thus making these corporate entities rulers of the truth.
IN fact, they are unaccountable rulers of the truth.

If your a physicist in this world, and you disagree with Einstein in any way, express a belief in UFO's, or sometimes even show a realism for some of the things shown in the STAR TREK episodes,,, you are shown the door. The community will 100% throw you out the door. There's nothing to debate over there.

But with Covid-19, it's absolutely NOT cut and dried. There are no definitive statements from anyone on Covid-19. As you've pointed out, they've already proved some of the statements made about some of the treatments being talked about have been proven to be wrong and biased.

Part of the blame lies in their bad record keeping. Hospitals will make an automatic $12,000 for every Covid-19 patient they log into the system. And therefore, just everybody had Covid-19 damage, even in you had terminal cancer or were hospice before the entire thing started,,, they file you as a Covid-19 death.

Great Britain has recently admitted they have discovered the same thing happened over there and thus their statistics and record keeping have been skewed badly.

We do not know for sure that 200,000 Americans have in fact died from Covid-19 this year so far. The data on deaths recorded every year in the United States has varied so widely over the past 50 years, it's truthfully uncertain who many we could attribute toward Covid-19.

More on next buffer.

I really enjoyed the interview with Randal Schwartz. More of this would be great.

I'm sorry your son got Guillian-Barre syndrome. Of course that means he is not a candidate to get vaccinated, but that is precisely why it is so important that people who are physically capable got the vaccine. Because we don't want him to die of Covid-19 either, and for him it is other people's vaccinations that provide protection.

The 6 feet rule is an approximation based on research into how far virus-laden droplets will move when people are engaged in normal speech and similar activities. If people are doing something like singing, or exercising where they are breathing heavily, six feet may be too close.

My son in law had Guillain–Barré syndrome when he was a child and now can not take vaccines. So not all people that would respond to a survey 'would you take vaccine x yes or no' are stupid. Also 70% immunization rate would achieve this mystical state of herd immunity. Lastly, why is the US distance 6 feet and others ie the Netherlands is 1.5 meters where is the science in any of this? I wish Ahuka would be less disparaging of people with different opinions, calling people stupid diminishes what he has to say. What do you think zen-floater?

Hey Daniel,

Just wanted to reach out to you since I'm a fan of the HPR podcasts and I just heard your review on the TML festival. Thank you very much for the nice review and I'm glad you loved the show. We worked very hard on it to make it like this :-) I worked on the cybersecurity end of the operation, mostly monitoring for illegal streams.

Kind regards,

Cedric

Hey Daniel,

Great energy in this podcast. I generally don't like live music. That is not exactly true, I enjoy live recordings of music. But rarely do I enjoy attending the shows. This episode piqued my interest in checking out some of the virtual shows.

I appreciate your contribution! Thank you for sharing your experience.

I was not meaning to have a Christmas in July episode, that is just the way it turned out. It was more a matter of letting life get in the way, as the project was finished in mid December. That and I get nervous about having to short of a show, or not being interesting enough.

I've enjoyed listening to your last two shows. You presented a very clear introduction to the concept. It's amazing how such an apparently small topic can unfold into something so complex and interesting.

On a tangent, I'm doing exactly this calculation for a project at work, and this episode showed me a simpler and more easily explained way to do it.

The supreme court ruling only applies to those crimes covered under the Major Crime Act. I don't think anyone is going to get out of paying taxes in Oklahoma anytime soon. Here's a link to the ruling

https://www.supremecourt.gov/opinions/19pdf/18-9526_9okb.pdf

Quite entertaining, is zen-floater channeling 51-50? I call it quilt logic, pieces sown together that sometimes are beautiful and sometimes end up as pieces relegated to a bin in the attic. As far as the ruling, the supreme court ruling only applies to crimes covered under the major crimes act, so all the other oklahoma not existing anymore doesn't apply. Here's the link to the ruling https://www.supremecourt.gov/opinions/19pdf/18-9526_9okb.pdf, read the first paragraph. Also, I'm sure people in the UK, including occupied Ireland, probably don't care about Oklahoma, the reservation or electoral college with all the real threats to their own sovereignty that exist from the German empire. Keep the shows coming they are, if nothing else, entertaining.
PS editing the show notes is not editing the content. I suspect all show notes are edited somehow to fit the formatting scheme the admins use.

Very interesting discussion. It made me think a lot about the subject.

When I was a kid (1950's and 60's) tattoos weren't "cool". The society I grew up in (working class, Greater London, then Norfolk) was not supportive of them. They were things that people of "lower class" had - or at least, that was my impression.

I have tried to shed as much of this type of attitude and prejudice as I can, but I still don't find myself wanting a tattoo. I have no problem with anyone else choosing to have them though, and in some cases I admire the choices they have made.

I have never voiced this opinion to my kids (as far as I know), but neither of them were keen on the idea of having tattoos when I asked! The prospect of making a permanent bad decision about them was certainly a factor.

Thanks for the thought-provoking episode.

Dave

Hi Zen_Floater2,

the show in question came into my podcatcher showing the title:
"Devuan review - and commentary". I got the impression, the show would be about Devuan while not knowing at the time, what a Devuan might be.

After listening I asked my self, why You did 2 topics under one headline, me not seeing the connection.

Im pretty sure HPR-Folks noticed that too and might not have bothered doing a comment, if each topic were put in a show of its own.

Thanks for providing content, Zen_Floater2.

Jan (lacking Knowledge of English)

Hi Andrew,

Regarding 'geodesic' I found some answers here:
https://www.etymonline.com/word/geodesic

So, 'geodesic' is from 'geodesy' which means "surveying".
Then 'geodesy' is built from 'ge' (pertaining to the Earth) and 'daiein' meaning "to divide".

This is just my limited summary, see https://www.etymonline.com/word/geodesy for the fuller definition.

Enjoying the series; more please!

Dave

I've got OpenBSD on a Mini10 as well (love it) but the graphics are slow on the GMA500 chip (no Polsulbo driver so it falls back to using VESA). Does yours have the same chipset and did you find accelerated drivers for it? Or do you just use it at the console (where it's pretty snappy).

I've upgraded mine to the maximum 2GB of RAM. put a newer SSD in it, and replaced the BCM wireless card (which never worked reliably) with an Atheros. But it's a wonderful little unit.

Thanks for the episode!

You only get one body in life, so why not decorate it?

A short devuan review so im allowed to post this here then a full episode of my opinions on race and american politics

I love the idea of a bootable SD card reading /home from an encrypted hard drive, rendering the computer without the SD card "a brick". Great model.

Very interesting things that I had no idea about.

It was not Zen_Floater2 intention to have shownotes for this episode. When posting this show, I added the shownotes and tags to this episode.

The changes made were as follows:

26c26
< Tags: Devuan
---
> Tags: Devuan, Debian, sysvinit, OpenRC, systemd.
30c30,31
< I have no notes for this review
---
> From Wikipedia, the free encyclopedia
> Devuan is a fork Debian that uses sysvinit or OpenRC instead of systemd, which is the default in newer Debian releases. The Devuan development team aim to maintain compatibility with other init systems in the future and not detach Linux from other Unix systems.

HPR is an open platform and it is very troubling to find out that it has been had.
Someone felt the need to troll the platform with political statements backed by doubtful arguments wrapped in a misleading title.

I think you overstated the security aspect of read-only filesystems. Even if you set it to read-only at the block device level, it won't stop a rootkit or kernel exploit from writing to the drive. Some USB drives, SD cards, and occasionally hard drives, claim to support device level read-only mode, but even then, they almost all have writable firmware that could be maliciously modified by software on the host (see BadUSB). The only consumer hardware I know of that supports anything close to physical write protection is the CD-ROM, and even most CD-ROM drives keep their firmware on a writable flash chip.

Most of these are advanced attacks that average person will ever have to worry about, but worth keeping in mind. Read-only root filesystems are mainly meant for resilience against power failures and simple unprivileged malware, but it's not meant to provide any true security against sophisticated attacks. That's why we have UEFI SecureBoot.

You are entitled to your political opinions, but please title your episode appropriately.

I could talk about some of the accuracy of many of your statements, but I don't believe that this is the proper forum to do so.

Very interesting listen! Probably more interesting than an episode about Devuan to be honest.

We do not listen to shows prior to posting, to ensure hosts are given the freedom of speech.
See: http://hackerpublicradio.org/stuff_you_need_to_know.php#not_moderated

As noted by the commenter's, the shownotes do not accurately reflect the content in the episode. I have therefore updated the shownotes to more accurately reflect the content discussed.

For all listeners, there is 2 minutes of discussion about Devuan, the remaining 32 are political commentary.

I will no longer trust, or listen, to this contributor.

This Podcast is more about American Politics then Devuan/Debian to be honest

I thought your views were interesting. I was particularly interested in how you highlighted that CJDNS was going to monetized and Yggdrasil was not or at least yet.

I've read about CJDNS, Yggdrasil and IPFS and I'm not sure exactly how all these overlap. My "limited" understanding is CJDNS and Yggdrasil "are" just the network but IPFS is the network plus a network storage system. I don't understand how IPFS network finds things or works. Sure it uses a hash, I get that, but the mechanics of finding the hash, how it determines what pieces of multiple copies it routes back and how I don't get yet.

It would seem to me if we could get something like Yggdrasil for the network that could have multiple encrypted hops like I2P or Tor and then have a store like IPFS, BUT you could choose what data you "mirrored" (like torrents or IPFS or zeronet)...well we would really have a kick ass open net that anyone could publish on anonymously and people could choose not to "mirror" some of the more seedy parts of the darknet.

I think these are coming together. I wish it were faster.

Python is ancient, ever heard about Rust?

I completely agree with the level of learning with computers today, so much of computer programming is opaque. Learning today seems to be, "oh i learned i needed to do sudo infront of apt-get, pip-install blah". Old computers, slackware install disks, forth on microcontrollers is the place to go to actually learn. Thanks for the show. Good to hear the roads are bad in other places than northwest ohio!

I enjoyed your talk very much, and it has revived my project of creating this kind of resource to facilitate community with minimal dependence on The Cloud.
Thank you.
I hope you can manage to do a follow-up talk with details for community builders that would help us do the same and build on your experience.

I'd also enjoy hearing more about manor.space.

The co-op style of hosting services (also discussed on episode 2411, "Co-op Paradise") is something that I find very encouraging!

I would love to hear more about how you built out this network. Great show!

From the title and the show coming from operator, I thought this would be about some cool way to find bugs in code. I was surprised to hear this was about real life bugs! Good luck operator, I feel your pain.

The Amazon product based on Postgres 8 is called Redshift, based on Paraccel.

I found it surprising that Ken would call it "the dark side of teaching maths in HPR" since I disttinctly recall in a community news show, not long ago Ken himself requested someone to do a show on Fourier (or was it Laplace) transforms!

I do like this topic. Look forward to the next episode.

Couldn't hear Martin at all, just a low mumble.

I really enjoyed the interview. Good solid information about an open source project.

The discussion about licenses and contribution agreements was interesting and informative. For example I really liked the way Fred explained how LGPL works in the context of projects like Big Blue Button, and how it compares to AGPL. Thanks for the show!

Hello

We have Firefox as both Flatpak and Snap

Thanks for this one!

keep going with this, great topic

I'm looking forward to more shows from this person.

Thank you for this episode, it's a nice gentle introduction to the topic, I definitely look forward to future episodes.

Glad to hear it!

It was not nearly as challenging as I had expected given the tools on pcpartpicker. The hardest part was actually finding things that could ship! I had to swap parts on the build here and there via that site before I finally got everything together but it wasn't awful.

Happy building!

This guy Seth Kenlon wrote a book that might be useful to the budding game programmer using the 32bit. Developing Games on the Raspberry Pi: App Programming with Lua and L�ve, he has friends that need coffee!

You *really* thought I wouldn't have done my research before recording??

**FOOLS!!** Mwahahahaa....

I had already found out about the new pricing scheme from an inside source in the deep web way before my review, and given the changes and all the red tape usually involved with such things, I knew it was worth putting that information out there for humankind to behold.

And since your assumption of my lineage was an extra benefit (I'm not Italian), I can now leak this cable from the "Fratellanza di Correzioni"...

(Thanks for the recursively recursive review. My skin is pretty thick. ;-) )

It's been at least 15 years since I attempted to pick all of the parts and build my own PC, but after hearing your talk I think I may give it another try.
Thank you for the inspiration.

Sorry to say, but I found the sketch not funny at all. Not because I’m a trump supporter (far from it), but it just was not funny in a comical sense. It gave me a sense of „fremdschämen“ and I had to skip over it after listening to the first minute or so.

Please also work on your audio balancing. First there was low-volume talk, then suddenly a much louder techno jingle (right before the sketch).

I'm glad you liked it. I have one more already uploaded and in the queue, and I just finished writing a third one. So there is more to come.

Great show! My wife and I are avid bird watchers and this year I added taking pictures of them (the birds) to the mix and I've wanted to process some of those photos and often thought of the gimp. Looking forward to more tutorials, if they're half as good as the libre office set they'll be awesome. Thanks for the show.

You can set up Fuguita via OpenBSD to actually lock all root access writes OFF. In this case, the filesystem is read into memory on boot, then that filesystem is locked down for the duration. No one can make any changes to the system from that point forward. It could be run in QEMU and even lock down what drives could be accessed with the dd command as well. This makes any kind of attack, absolutely impossible.

I've been using a Kinesis Advantage for years. Owner of two and I love them. They've helped with my RSI quite a lot.

Couple of notes: the esc (and fn keys) are membrane, i'm pretty sure. One can also program the keyboard to beep on all key-presses which is useful to avoid bottoming out.

I agree with your two week skill acquisition time with the keyboard. I find that many years later I still want to use the advantage +/= and ~ locations on any other keyboard.

Thanks for sharing this one!

The idea of running your home router off a read only filesystem is very interesting.

Really enjoyed this one. Found myself nodding along in agreement and finishing some of your sentences. Lots of good refresher and some new tips in here for me. Thanks a ton for submitting this one!

Good episode. Thanks for reminding me that I know nothing about networking.

Hi Windigo!

Thanks for the link. I'd love to get my old Sheevaplug up and running again, and this looks like the site to help me do so.

I don't actually have a use for it at the moment. It had a USB disk on it and I used to use it as a Git repo (a package called 'Gitosis' I think), and could access it when away from home. Then it was a "playground" for learning about Bind. Then the disk crashed!

Anyway, this is now on my to-do list. Thank you!

Dave

Dave, I hope you'll be excited to hear that the Sheevaplug is still very well supported by Debian. I had one up-and-running with the latest version until very recently.

Here's a resource I used to set mine up: http://www.cyrius.com/debian/kirkwood/sheevaplug/

I have a hard time justifying keeping mine running, what with the Raspberry Pi and others being so much more full-featured and powerful, but it's definitely an interesting piece of hardware!

so in the end i finally got the chorus of that one bloodhound gang song for which this episode is relevant. nice!

I have been using pyenv-virtualenv for a month now, and I am reminded every day of how happy I am to never be running another `pipenv run` or `pipenv shell` ever again.

fluffy mentioned Atom "tombstones", defined in 'The Atom "deleted-entry" Element', https://tools.ietf.org/html/rfc6721

Hi Dan yes you are quite correct it was indeed the Tefifon, I couldn't remember its name. It certainly is a very strange device. The one they had at the museum of communication wasn't in working condition at the time, they were in the process of trying to repair it I hope they succeeded. I must thank you for bringing this up as I really enjoyed rewatching the YouTube video link you gave which gives an excellent introduction of the device. The sound quality seemed surprisingly good. I watched the video while sitting out in the sun in my back garden. All the best MrX

Is the audio format you referred to the Tefifon (https://en.wikipedia.org/wiki/Tefifon)?

Never seen one in person but there is a good overview of it over on Techmoan's YouTube channel: https://www.youtube.com/watch?v=nBNTAmLRmUg

Hearing Fifty made me miss him again. And I must admit I was surprised to discover that I appeared in this episode. But good work on the reviews folks.

I love this book and can't wait to listen to this episode. Dave Hitt is amazing and has other stuff to listen to.

Visit his website for more stuff: http://www.davehitt.com/podcasts/.

While I agree with most of his opinions and information, there have been a few things I absolutely disagree with him about, but I get to hear a different point of view sometime and

Thanks for the valuable feedback Claudio! We'll tackle this as part of a future episode.

Thank you for your feedback. If I interpret you correctly I think you may have misunderstood the spirit of my earlier comment.

I was replying to crvs when he mentioned the use of shebangs in the context of writing awk scripts. I took him to mean that this particular episode had helped to provide an insight which assisted with his understanding.

In my reply I pointed to the series that b-yeezi and I had done on awk where we'd tried to introduce people to this tool and had made many many references to the gawk manual along the way of course.

There is no contest with the gawk manual itself, if that is what you were implying. The manual is obviously the most comprehensive and definitive resource on the utility and the language. The resource which b-yeezi and I had tried to provide was simply a way into concepts which may have been daunting and somewhat inaccessible to some.

Our role was one of supplementing the manual itself, not of superseding it in any way.

I hope this clarifies any misunderstanding there may have been.

Thanks for this.

You are of course perfectly right. I tend not to think of this way of doing things - maybe because I originally learned Unix on HP-UX and SunOS a long time ago. I might be accused of being a little stuck in my ways!

I did think of mentioning this in the show but didn't do it because it was a "snippet" and I didn't want to go into too much detail and make the episode too long. I did link to the relevant page in the documentation (https://www.gnu.org/software/bash/manual/html_node/Quoting.html) however.

Feel free to add to the Bash Scripting series yourself. I look forward to hearing a different view from you in due course.

Personally I feel like the best and most complete resource for learning AWK is the gawk manual:
https://www.gnu.org/software/gawk/manual/gawk.html

There are actually more than two types of quoting in bash. In addition to 'single' and "double there are also $'ANSI-C' and $"localized" quotations. For this problem I would have used the $'ANSI-C' quotation:
alias show_network=$'nmap -sn 192.168.0.0/24 | awk '/^Nmap scan report/{print ""; print; next}{print}''

Personally I find this a bit more readable. It might not be as portable but that shouldn't matter as the episode specifically addresses Bash.

Here are the expansions for the ANSI-C quotation in the Bash manual:
https://www.gnu.org/software/bash/manual/html_node/ANSI_002dC-Quoting.html

Thank you for sharing. I have now fallen down a rabbit hole of links to software I didn't know I needed. :)

I may just try this. I'll probably use different parts.

Thanks for the comments, I will be covering how I go about dismantling the models, removing paint from the casting and plastic parts as part of the series. My next episode will be about the basic tools and materials you need to get started.

Looking forward the series!
I haven't ever stripped Matchbox cars, but I have done fair share of miniature stripping. I'm interested on hearing how you handle this as these models have both metal and plastic parts.

Wow! I didn't realise skynet was really nvidia. I'm going to bin my graphics card right now. Thank you so much for this heads-up!!!

It's been awhile since I needed to do Python package management, but thanks to this episode I'm ready next time the need arises.

Thanks for the comment; it's much appreciated.

My interest in fountain pens didn't really develop until I was beyond school age. School had the effect of making me dislike using them because I was forced to do so. I have been a frequent ballpoint pen user from my university student days, because it was easier to write rapidly with one when in lectures or other places where rapid transcription was needed.

I can see how an interest in the older 1950/1960 designs of ballpoint pens would be a thing. Quite collectable!

Your hand-made journal sounds wonderful, with the leather cover too! I have never owned anything so good, but I do have some notebooks that I like so much I have never used them and probably never will! Your reaction to your journal is perfectly understandable.

I'd like to hear more about the pen collection and the journal if you feel you could make a show about them :-)

Hi. Thanks for the comment.

I know what you mean; I'm no artist myself. My daughter took art and science at school and has developed her art skills since then. She always tells me to just keep sketching if I want to get better at it. That's what she has done to try to get to a place where she can start to combine her science interests with her art.

I guess the message is that you can develop abilities if you keep trying!

Dave, my apologies for the late comment, I had intended to get it in prior to the community news, but, life happens.

I too have always been fascinated by these tools. My fascination was multiplied by both of my parents working in parallel industries when I was young. My father worked in an art and drafting supply house, my mother in an office supplies store.

Instead of turning to fountain pens, my disposition is toward ball point pens. While I do agree that they aren't the greatest writing tools, I have leaned toward advertising pieces and novelty pens. I have pens in my collection from as early as the 1950s and 60s. Mostly local business advertising, a few national chains/brand names.

Art class in middle school introduced me to papers and textures and artisan papers. I am a proud owner of a 100% hand made journal. (Not by me, I don't have that level of skill) the 300 pages of paper is all hand made from recycled cardboard and denim an the entire volume is bound in hand tooled leather. It is so nice, I am scared to write in it...lol

I'm glad you enjoyed the show.

In having run through it earlier, when Mumble refused to record anything for me, I obviously gave myself an accidental rehearsal, so maybe the show wasn't as disjointed as it could have been :-)

Yes, it's more fun when there are two of us to discuss and banter a bit, so I prefer the normal setup.

Thanks clacke.

I think I was confusing "I have learnt this stuff" with "I know about this stuff" and got a bit muddled! Now I think of it, I was learning about blood groups more than 50 years ago!

It's an interesting subject though and I must go and refresh my dwindling/dwindled knowledge about it all.

You did a good job, Dave. Though I am guessing you would like to have Ken back next time!

Dave mentioned in passing that 0+ would be an unusual blood type.

One might think so when just looking at how the alleles work. All you need is one A or one B allele and then the 0+ would be overruled. One might be tempted to believe that it's 25% each of 0, A, B and AB. But that assumes an even distribution of genes.

My blood type is A+, and I grew up being taught it was the most common one. When I moved to Hong Kong I learned that blood type distribution is not universal. Someone told me my blood type was "unusual".

While A+ is not exactly unusual, in China (and I assume HK) near 50% of the population is 0+, while A+ is at around 25%.

It's also not as dominant in Sweden as I was led to believe. 37% of Swedes are A+ while 32% are 0+.

In the UK and US, 0+ is somewhat more common than A+, the reverse of the Swedish distribution.

I appreciate the feedback, tuturto. I also feel the Community News is an important part of HPR, and the show must go on as they say!

This episode leaves me wishing I were a writer/artist. It is an interesting medium that my daughter (an artist) may take up, since she had been sketching pen drawings lately.

Thanks for keeping flag of Hacker Public Radio high up and doing the community episode all by yourself. Listening to recap of whole previous month worth of episodes is one of those things that I look forward when a new month starts.

Its sad that ahuka considers his fellow citizen on the other side of the political spectrum his enemies. Also, all governments, not just russia, sow political discord for their gain, just listen to voice of america and check out all the cia ops in central and south america. Quit picking on russia as a straw man.

In addition to the archive.org location above, the talk is also available on the federated free social web at https://conf.tube/videos/watch/c81c92cd-b023-4a32-966c-bb2233e35483 .

This sounds like very useful software; thanks for the introductory episode!

I confused myself and created a Nix Python virtualenv (which doesn't work) when I thought I was creating an Ubuntu Python virtualenv (which actually does work).

Because by telling you that he doesn't know much about Jitsi operat0r has just invited you or anyone else out there to do a follow up show if you happen to know more.

Herd immunity is wonderful, and it is why vaccination is so important. When we have a vaccine (and the most common estimate I have seen is 18 months on that one), and when we ramp up production and get it out to over 300 million Americans, we'll be in a much better place.

Chloroquine is different from Hydroxychloroquine, my mistake. There are medicines that can help peoples own immune system get the through this (and many other diseases). Waiting for a vaccine is untenable for us all, we will all end up in the economic toilet, herd immunity is what we need, lets get going. (unless your at risk, hang back, 6 feet or 2 meters, and let the 'risk' takers get out there and pick up the pieces.

These days I probably only listen to about ten percent of episodes.

I don't know why this is compared to the near 100% I listened to when I first found HPR. It is probably because I arrived at a peak, right slap in the middle of the legendary Ahuka Libra Office series exactly when I needed a leg up doing spreadsheets.

And also around that time Klaatu and Dave were doing a lot more.

But at no time have I complained about any episode.

My mother used to tell us, if you can't say anything nice, keep your mouth shut.

And nowadays I don't do any podcasts here because I have become too conscious that there will be listeners who know more about what I am talking about than I do.

But comments like the one criticising Operat0r for starting his cast by saying he knows little about the subject is not exactly encouraging to others, is it?

Why indeed should anyone listen to an episode of HPR? The only answer I have is because it is of interest to you. I think of HPR as a party with a bunch of friends, not as a college curriculum. I listen to the ones I want to listen to, I skip the ones I don't. And I am not in the least bothered to think that there are people out there who don't want to listen to my shows.

I prefer free software because I like the freedom to do the things I want to do and live the life I want to live. Here's an excellent podcast discussion of these rather difficult questions.

https://powerhour.alexepstein.com/2020/04/23/power-hour-4-22-20-onkar-ghate-on-a-more-american-approach-to-covid-19/

You can download and listen without copy protection and there are no advertisements, however be aware that the above podcast is NOT under CC license, but linking should be fine. They take a somewhat hyper-rational approach to the issues, and some people might prefer an emotional perspective, but even if you disagree with their conclusions at least consider the way they methodically work through the key points.

Economics is about deciding the allocation of precious scarce resources, and inevitably this must involve a trade-off - very similar to Engineering. What is happening right now is that the lives and livelihoods of young people are being sliced away for the benefit of the older demographic. Despite this ethical dilemma, very few of the commentators are willing to even give the slightest recognition of those being sacrificed. Only those people who start with the understanding that a trade-off is involved are genuinely engaging with the problem.

Thanks for this. I have struggled to find devices on my network in the past, and eventually resorted to using nmap (which I used to use at work years ago).

I was not aware of arp-scan, and have just installed it. It's very much more helpful when searching for that new Pi just added to the network.

I'd not noticed before that "Raspberry Pi Foundation" had become "Raspberry Pi Trading Ltd" apparently with the arrival of the Pi 4, and that the MAC address base had changed then too.

To the person moaning about 'having' to listen to, or 'being expected' to listen to, a podcast about jitsi in which the host first says he doesn't know a lot about jitsi.

I think HPR might not be what you are looking for.

And you need to learn where the delete or skip button is.

In the few shows I have done for HPR, I have always been very conscious that there are, inevitably, people out there who know more than I do about what I am talking about.

Why don't you do a show about something and show us all just how smart you are?

As Jitsi seems to be making the rounds coming out on top as the open source alternative to ZOOM this was really interesting and made me want to play around with it.

Thank you very much

Romans also used tersorium or xylospongium, which is sea sponge tied on a stick. Those were in communal use and just rinsed in a bucket of water and vinegar in between of uses.

Also, a big portion of humanity uses hands (or rather a hand and water) to clean themselves and actually consider using toilet paper disgusting as it can't clean as well as water can. Different cultures and all that.

I was wondering if I am expected to listen to a podcast if the first minute or so is the presenter explaining how they don't know much about the what they are about to talk about?

Seems the listeners time isn't being respected.

I was thinking about checking out jitsi, so this was a welcome find in my feed. Thanks for doing this.

Its a shame that ahuka takes a decent look at the pandemic and has to drag his form of left wing politics in to it. Ad hominem attacks make you feel good but don't add to the strength of your argument. As far as Chloroquine and its possible usefulness in helping people recover from this disease here is a link to a National Institute of health article about this drug https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1232869/ dated 2005. This drug may be useful but peoples politics are getting in the way of seeing that. Who's rational. Lastly its easy for pensioners to say stay at home indefinitely, some of us need to go out and work there are many jobs you can't do from the comfort of your home in your pajamas. Poverty is a bigger killer than any pandemic

On a more relevant note: I love these minimalist approaches. A friend swears by Porteus, but that's still 300 MB. Tiny by most standards, but wouldn't fit on your card.

I think it's worth mentioning that while you said it left a few megabytes on your card, the core of Core is a mere 11 MB. He tried for the longest time to keep it below 10 MB, but had to break the barrier about 10 years ago.

It's still the only distro that fits in an email. :-)

Hadn't heard of NanoBSD before, thanks for bringing it up.

Thank you Ken for a forceful and enlightened rant on the archiving mentality, the evergreen value of much knowledge, and the need for self-contained show material. I agreed with not only the general sentiment, but probably with every word said.

I'm glad you don't believe in editing things down.

I have never used Tiny Core Linux, but years of listening to ... Linux Outlaws probably? ... have still taught me the name of its maintainer by heart, because it's the most Bond Villain maintainer name ever.

SHINGLEDECKER!!

Its hard to believe a guy from Indiana would advocate for the elimination of the electoral college. You definitely would not need to vote if you live in Indiana if there was no electoral college. The US is not a democracy, its a republic big difference. The primaries and caucus system is a political party system and should not be confused with how Presidents are elected. One last thing health insurance is not health care. When you say universal health care your really saying universal health insurance. You still will have to fight an insurance company with "universal health care". Send Lawyers, guns and money the sh-- has hit the fan!
good show entertaining

Oh cool!

When I was using Matrix+IRC before, unauthenticated FreeNode was still ok, but now I know what to do if I start using Matrix again.

I have been using XMPP and Biboumi, but didn't host my own and the hosted ones have not been reliable. I miss IRC, so I may come back to Matrix soon.

I loved the sketch at the end. It was very funny, and very creative.

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.
https://www.worlddata.info/average-income.php

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.
Regards
Gerry

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.

-timttmy

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.

!!! Please note we *do* use your email address everywhere !!!

It is associated with your episode and will live on forever

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 ?
How much do you make as a volunteer fire-fighter ?
Can you explain the role of the Junior Fire-fighting teams ?

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.
Don

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.
/ Gerry

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

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

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.

DeepGeek

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.

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.

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.

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
[[ '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

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.
