Hi All,

It is a great idea to record a piece of silence to use as a "Noise profile" for using with the "Effect > Noise Reduction" feature in Audacity. However please do this *before* you upload it to HPR.

It is opening a can of worms to ask hosts to submit this before having a process in place to deal with it. If we learned anything from is it included or not Intro Outro thing, is that everyone will do their own thing. Will the silence be at the beginning or the end ? What if it's in the middle ? Was the silence intentional ? Will truncate silence work ?

So great idea for a host but please, please, please do not do this.

I think this is a perfect example of hacking. Fantastic!

Great show - this of course is an ugly mirror showing exactly how time flies and how we have been getting old ever since...

Congrats on earning your amateur radio license. It is always interesting to learn some of the differences between operations in different countries. For example, here in the USA, it is generally frowned upon to call "CQ" on the 10M and 70cm bands as these are littered with repeaters. We often simply transmit our call sign.

I look forward to additional amateur radio episodes, and am planning to post one about my Go Box build, assuming I ever get out of the planning phase and into the building phase.

Thanks for the comment, Trey. Yes, the Walkman is vintage nowadays and we're in the same boat old-age-wise. I have a couple of things that could probably benefit from being recapped, but I've never gotten into the weeds that far yet. One of these days when I've got some time in front of me, I would like to replace the capacitors in my Pioneer reel-to-reel tape deck. I feel like this would probably help with the weak left channel. No time right now, though.

Thanks for making this, I do remember getting one back in the early 80's, however that is no longer around, shame I threw it out many years ago now.

I'm going to get out my Dad's Walkman on the weekend though and see if it still runs. I kept his Walkman WM-F2015 https://www.radiomuseum.org/r/sony_walkman_fmam_stereo_cassette_player_wm_f2015.html as I knew it was special hopefully it still runs, if not I will fix it!

Thank you for sharing. Tinkering with vintage electronics (Wait! Referring to the Walkman as "vintage" makes me feel really old.) is loads of fun. Do you find the need to replace capacitors in equipment of this era? I have noticed with various radio gear of similar age the capacitors have drifted far from spec.

Keep up the awesome podcasts!

I'm glad you enjoyed it. There are more in the pipeline, but once they are done there won't be any more in this series. I wrote these 20-something years ago, and I still get happy users who find them on my Web site.

Thank you for bringing back memories from early in my computer career. I still have a MSDOS 3.31 Emergency boot disk (Because it was the first to support hard drive partitions above 33MB). For the longest time, I kept it in the very front of my floppy disk case. But when I finally tossed all the old PC floppies, I relocated it to the esteemed location of stuck to the refrigerator door with a magnet.

Likely won't boot anymore, but still brings back memories.

Keep up the good work!

I'm not sure if you've encountered GNU recutils before

https://www.gnu.org/software/recutils/

but it's a nice flat-file way of storing & querying data in a format similar to what you described. It's fairly easy to convert to CSV or other tabular format. It plays nicely with version-control, making it easier to tell when a "column" (really a row in a group) has been edited because the diff just shows that one "cell" rather than a whole CSV line being modified.

It's also pretty flexible when it comes to omitted or duplicate fields. I've taken to storing our household address book in this format and then transforming it into other formats as needed.

Just checked the last quarter and there has been a recovery of subscribers up 11,000 to prelockdown levels. This I suspect was triggered by the return to work and loosing of restrictions.

As winter hits the Northern Hemisphere and another wave approaches, I predict a falling of numbers again.

I'm always of two minds on low cost tech when I see it, it's can be a burden on one side of the economic ladder and a boon for another. I usually fall on the side of access to technology can provide a net good. I do however feel compelled to point out Mississippi has the highest deaths per 1 million people in the United States.

As i was enjoying the show i logged into my new (to me) arm based running laptop (show coming) running slackware and my fortune said "I have hardly known a mathematician who was capable of reasoning" Plato.

I made a small error in my comment to the subject about branding. I said the bit between TTS and raucaus music was an advert for AHH, but of course it is for archive.org.

Now, I like the TTS. It gives me the chance to decide early whether to carry on listening, or press delete and go to sleep.

But the current TTS engine/settings used are boring. She sounds like a woman who has been awake for a week continuously. No prosody, no intonation. eSpeak is much better IMHO.

It could also speak faster for me personally, a lot faster.

But I know all you photon-dependent types won't agree ;-)

I loved this episode, Klaatu. Somehow I find it really entertaining to hear all about the benefits and difficulties of tables and it's something I've dealt with a good bit myself, but mostly in the context of eBook editing. In addition to the problems you mention, another one I find vexing is the impact of font sizes on tables. One of the best accessibility features of ebook formats and ebook readers is the user's option to change font size. When you're getting older like me and you typically increase the font sizes, you find that tables rarely survive the change unless you're on a big screen like a tablet. I will try almost any option to avoid making a table in one of my own ebook edits because it's too hard to predict screen size and font preferences. Lists will usually do the trick, just as you proposed in your episode. Now I wanna go take a look at your ebook...

Most Freenode channels have since moved to libera.

I'll make a show about why and a show about how to connect to libera, but here's the spoiler:

https://kparal.wordpress.com/2021/06/01/connecting-to-libera-chat-through-matrix/

- Instead of #freenode_#oggcastplanet:matrix.org use #oggcastplanet:libera.chat (yes, they have their own gateway!)
- Instead of chatting with @appservice-irc:matrix.org to store your login and password, chat with @appservice:libera.chat

Things have happened with IRC since 2016. In 2020 Thaj Sara recorded HPR 3034 http://hackerpublicradio.org/eps.php?id=3034 as an update to this show, explaining how you can make Matrix authenticate your nick when it connects to IRC.

Thanks, Ken.

I have been using these prefixes for decades, and take them for granted. Thanks for the reminder that this is not common knowledge.

It also reminds me of a question for which I have never found a good answer. In North America, capacitance, is expressed in uF (micro Farads) or pF (pico Farads). But nF (nano Farads) is not used. Instead you will see values like 10,000 pF or 0.01 uF.

Go figure.

Nice exposition, some things would need further / correct explanation also to klaatu (!), blame it on Porteus' not-so-well own documentation, now and here only this what is VERY important (though not Porteus specific): Porteus' XZM modules (as they are aufs / squashfs as in eg. Slax) do not "overwrite" anything on your machine, they interrupt your file system calls and make them believe that there are things that are not really there, so deactivating a module or restarting gives you an unchanged file system again, and if two programs conflict in shared resource file versions, you need not uninstall something, you just activate / deactivate modules - those modules may just be different versions of one library file, i.e. you can make a single file or a directory a module, and always your "initial" will not be corrupted by workarounds

They probably don't but I did. The goal of this series is to communicate via audio the location of the symbol.

Although looking at the definition it's not a bad word to use.

https://www.thefreedictionary.com/Suffixes.htm

Suffixes are morphemes (specific groups of letters with particular semantic meaning) that are added onto the end of root words to change their meaning. Suffixes are one of the two predominant kinds of affixes—the other kind is prefixes, which come at the beginning of a root word.

Do they really call exponents "suffixes" where you're from? I've never heard that usage before.

Both e8hffff and CoGo are arguing like lads in a pub. Sure their arguments makes some sort of sense when you've had a few pints. In the cold light of day you find yourself wondering just how drunk you were.

On those occasions I vowed - "Never again". Great advice to both.

From my point of view Dr Fauci is a skilled virologist and immunologist. I had heard him on virology podcasts long before COVID-19 and found him very impressive as a scientist and as a human being.

You refer to risk analysis, and you are right, we didn't deal much with this subject in our show. You write of the risk individuals are willing to take, and I often see this point being made. The point made less often is the risk each person poses to others. Unwillingness to avoid crowds, to consider physical distancing or contesting the need for a mask are stances taken in relation to the objector's risk. The risk to others seems to be disregarded or given very low priority.

I assume you're commenting on show 3445, which is a response to this show 3414.

You are of the opinion that common sense outweighs the knowledge achieved through the scientific method. History seems to disagree. The "common sense" prior to the discovery of "germs" resulted in the death of many who would have survived if hand-washing had been more common, for example. There are huge numbers of similar examples.

You make an assertion about masks, which I disagree with. You assert that your view outweighs the research we cited in show 3445 yet your only support for this is that you state it. This seems typical of the current trend to put forward opinion as superior to fact.

You mistake trust in the scientific method and the results that this method produces, in comparison to those who misrepresent this method and these results for their own agendas and profits. Agreed that many politicians, industrialists and even some dishonest scientists are known to do this. However, where human beings may sometimes be unreliable the properly conducted and peer reviewed scientific method is not.

In general viruses "break in" to cells in order to use their replication machinery to
make more viruses. In the case of SARS-CoV-2 the spike protein is the part of
the virus that is used to "break in". It's not dangerous in itself, it's part
of the toolkit this virus uses to gain control of cells and make more viruses.

In order for the human immune system to fight against a foreign chemical or
"antigen" (usually a protein of some kind since living things use proteins as
building blocks) it needs to be exposed to the antigen and build antibodies
(and other immune responses). Many of the vaccines use methods of delivering
or generating the spike protein in order to "teach" the immune system what to
be alert to. Some use "killed" viruses instead, but none of these are in use
in the USA and Europe to my knowledge.

So, vaccines are not inherently damaging, as you state. They cause your
immune system to react, which is the point, and this can result in soreness
at the injection site, fevers, aches, and similar symptoms. Yes, anaphylactic
shock can result from an allergic reaction to the vaccine itself - as it can
from peanuts, eggs, insect bites or seafood for example. In the UK, as I said in the show, we
are asked to wait for 15 minutes after our vaccination in case such an
allergic reaction is triggered, and there are medics nearby to deal with any
such emergencies.

Better late than never, I guess.
The source you give is questionable at best. As Bob pointed out, France doesn't have a age of consent, so the law actually added one, even thou it is defined weaker than in the US.
As for Germany: as I said, it already IS 14. And it won't change, because 14 is also the start of (limited) legal liability, and germans generally don't consider the idea of "no sex until marriage", and teenagers shouldn't have to go to jail for trying themselves out (Rape is a different story, because the lack of CONSENT).
There is no recent move, and no movement, and the cited attorney doesn't even exist, which should be a red flag, no matter the stories content!

Good show.
One exception i'll take is that ALL Americans turn to Anthony Faucci for our information, is just not true, the man is flawed and so is his wife.
The only thing lacking in both podcasts is a discussion of risk analysis. ALL people have different levels of risk they are willing to take. Politicians and policy makers creating one size fits all solutions, like arbitrary social distancing dimensions, leads many people to become suspicious and consider riskier behaviour.
I do agree with the earlier comment about using I feel or I believe language. That tends to be opinion.

Fulguris is a good one

As very good analysis that uses genuine critical thinking. One thing that I haven't seen anyone point out yet is that in the original show much is made of the idea that masks are not air-tight. Of course they aren't! If they were, people wearing them would die! I have worked in several hospitals in my career, and masks do a decent (not perfect) job of what they are intended to do. If I were being prepared for surgery and my surgeon said he would not wear a mask "Because I don't believe in them," I would most certainly stop everything and get a better surgeon.

Hi Nihilazo,

Thanks so much for doing the show, it was excellent.

It brought a tear to my eye to hear the story of my old Psion being so well appreciated and cared for!

I worked for university IT department here in Edinburgh, and my boss bought these devices for all of the managers in the department. I used mine a lot over the years. Occasionally I'd record audio on it, but more often I'd write notes in meetings or use its calendar and contact application.

I'm pretty certain it can output documents to a printer using a built-in IR device. I had an monochrome HP LaserJet in my office which would accept documents over IR. It was really useful in this regard. No idea how you'd do that these days - an IR device on a Raspberry Pi? Hmm...

Hope to hear more about your adventures with the Psion - and anything else "of interest to hackers" - in the future :-)

Dave

Consider that CoVID19 dangers are the Spike Protein, yet the CoVID19 vaccines create Spike Protein. Therefore it's a question of scale of damage. CovID19 vaccines/injections are inherently damaging. Some getting anaphylaxic shock and death from the injections.

Kingbeowulf. Polio was already being eradicated via hygiene measures. Also Polio disabilities are also the symptoms of other affects, like radiation damage, which was a new technology of the era and people got exposed to high levels. The Polio epidemic was caused by many factors. The Polio vaccine is definitely not the cause out of that disease. The modern spread of Polio has been via Polio vaccines. Do the research.

Measles was never consider dangerous during it being common, with people getting natural immunity and creating a better scenario than current. You've probably heard of the Brady Bunch episode of having a measles party. Well that was the go in that period. People got it and got over it. Near to zero issues and resulted in better outcomes of being naturally immune.

Vaccines are in themselves a danger and have caused many new conditions like Autism and SIDS, never experienced by most before 80's, before the vaccine regime. 1/54 births are now Autistic. Autism in communities that don't vaccinate are near to zero.

This is a perfect example of common-sense thrown out the window. A bane of the world today. You should never dispose of common-sense and replace it with mathematics. Mathematics, and when used is statistical pursuit, can only attempt to simulate scenarios from data supplied, or framed pictures of their very construction. Common sense is science, that of observed commonalities and events, even if labelled as anecdotal(said in conversation, wives tales, etc).

Masks are not advantageous as you are complicating a situation of natural body design, that of expelling toxins through the nose and hoping to breath in cleaner air. Masks unquestionably increase viral/bacterial load. Therefore creating spreaders. With the higher loads, comes elevate deaths and ailments, creating erroneous lethargy statistics for any said virus. That can result in political overreach/oversight as seen in CoVID19. The benefit of reducing virus particles with a mask is outweighed by the damages they cause. Common sense. No you don't need a PubMed article to comprehend that. Also consider some people correctly breath though their filtering nose, and other incorrectly through their mouth. Masks complicate breathing for those properly using nose, and espouse mouth use.

On weather seasons having an effect on viruses and contagion. You don't need to search for lab papers on cold weather and viruses susceptibility to disprove summer protections. Common sense should tell you that viruses are naturally burnt out of the body via a "temperature". Therefore Summer can only assist in raising the body's heat when infected, causing fast mitigation. This includes hot baths. You would also easily say moisture assists in virus survivable in the environment, making cold moist weather a disadvantage health.

Also consider your stance is based on trust of politician and science workers and industry. That is unquestionably a flawed stance.

Great to hear a show about a Psion PDA. I still have a Revo somewhere in need of repair. Never got round to getting it working directly with Linux but used under a VM with Windows XP and Lotus Smartsuite.

This is not a criticism for this podcast. But just something I come across once in a while.

I will here people say "I believe in this or don't believe that because I reason."

It's nice when people can declare themselves a reasonable person. It's different if others else views them that ways.

Klaatu, a very elegant rebuttal.
Hats off to you for your measured and thoughtful response and coolness
in the face of such astonishing ignorance.

I've long desired to own a 5mx (possibly running either Linux or NetBSD) but have never been able to justify the cost outlay to myself. Looking forward to hearing about your adventures with it!

Klaatu, your counterpoint is spot on and well said. The analogy to CPU design and construction is well done. There is a lot of chemistry and physics involved that even I have a hard time following.

As a chemist, I am befuddled by some of my colleagues forgetting the scientific method and singling COVID-19 vaccination as either unimportant or a "conspiracy", as compared to the dozens of other vaccines we all have taken. I sure a heck do not what to return to the "good old days" of polio, smallpox, diphtheria, measles, tetanus, hepatitis A/B, flu/HIB, pertussis, mumps...and don't even get me started on chicken pox...

I loved this show! Nice to hear about older hardware being used.

I applaud you both for addressing this with facts and patience, and without dipping into any personal attacks - well done, and an enjoyable listen - thank you both for challenging the other episode logically, and for bringing some sanity to the conversation - best wishes to you both

In the last community news I said that he checked a show and found that it was 'of interest to hackers'. I should have said he checked it and "it was not spam".

https://hackerpublicradio.org/stuff_you_need_to_know.php


*The audio of your show will not be moderated.*

We do not vet, edit, moderate or in any way censor any of the audio you submit, we trust you to do that. Aside from checking snippets for audio quality/spam checking, we have a policy that we don't listen to the shows before they are aired.

Klaatu, A science endeavour starts with a hypothesis that is later given weight via scrutiny from ALL KNOWN effecting factors. Your claim that CoVID19 dangers and affects are known and an accepted condition by Medicos, is false as that stance presumes ethics and truths were a part of employment and statistics gathered during the so called CoVID19 pandemic. It also presumes all Medicos are on-board CoVID19 Agenda, which is totally incorrect.

If you didn't shelter your mind or you only exposed yourself to filtered social media, btw not being offensive, you would know that it's common place for hospitals to place anyone with symptoms of CoVID19 (that includes influenza) into an induced-comma and then intubation/ventilators. This makes attending a hospital in this era with any cold or flu, dangerous, as ventilators are known to damage the lungs and should only be used in extreme situations where no other option is available. It's also common knowledge that hospitals around the world are refusing to use anti-viral medications, as it's not a part of the CoVID19 Agenda to use them, with early political demonisation. Hospitals are also sponsored for deaths and treatment of CovID19 with money lump sums. Therefore the deaths and surviving patients reflect the malpractice, resulting in bad statistics used in your SCIENCE assumption.

The CoVID19 vaccines another field of corruption and dangers.

Look at those show notes!
I wish science was as pure as you say it is but were money is concerned, and you can't deny people have gotten wealthy because of covid-19, the science gets tainted. Richard Feynman would often point out how difficult science experiments are to do, especially in biological science, were control of variables is almost impossible. Proof that the science around covid is as muddled as any science, can be seen when the scientists decided to vaccinate the placebo group in the study,
https://www.npr.org/sections/health-shots/2021/02/19/969143015/long-term-studies-of-covid-19-vaccines-hurt-by-placebo-recipients-getting-immuni
(yes that is the whole url). That decision was driven by opinion, not facts. Science is hard and flawed.

Trusting the experts can lead to things like systemd and them saying 'just trust us it works'.

Also, much of what we call science is actually engineering, developement of RISC architecture is probaby done by engineers, whose goals are different than scientists.

lastly a famous scientist said

'If you can't explain it simply, you don't understand it well enough.'

Albert Einstein

I had to play this show about 3 times to get all the content out of it. Installing and running Gnome 3 on OpenBSD is extremely easy as GDM does all the work for you. Setting up Pulse Audio is probably the hardest part most newbies have difficulty with. But you know, this Squirrel is sick and tired of heavy desktops. I'm also getting sick and tired of Intel/AMD64 platforms - the plastic CPU's from hell. And I long for the mainframe days where we just used a dumb terminal - I was happy then. I have a few OpenBSD servers to use via SSH which satisfy this urge but, I need to by some dumb terminals and put OpenBSD on my Rasberry PI 400 thingie and take my 2 chromebooks and just drown them both in a deep bathtub somewhere. There is no such thing as a perfect desktop, I hate them all. Those desktops always leave you feeling unsatisfied with life. Why do we even put up with desktops and what drives Fedora to continue on with Gnome? What are they going to get out of it? What will IBM get out of it? Everyone should run OpenBSD or NetBSD or Fuguita or how about GUIX with the HURD instead of all this linux stuff. We want something different on the computer table. Really, Gnome and SystemD is like a slow creeping cancer.
And a boring cancer too where your limbs fall off one at a time every 3-4 years.

"Now go out and play with this and come back with an example on how this is actually useful in the real world, and submit a show!"

Dave Morriss did so in HPR3413:

http://hackerpublicradio.org/eps.php?id=3413

Even though he concludes that this feature is awkward compared to the alternatives, it's great to have a less contrived example!

Through various hardware and software calamities, my podcasts have been out-of-reach for more than six months. Just recently, I've been able to remedy it, and this was the first HPR episode in my queue that I was able to listen to.

Oh, how I've missed HPR. Thank you for the thoroughly enjoyable episode!

Great episode. Nice to hear a few of the ones I've used and known about mentioned as well as some others I've not known about. One that wasn't mentioned that I recently came to discover is called Mojeek. More information about Mojeek below.

Mojeek: https://www.mojeek.com/

Great episode, gents! That was an awesome interview and I could have listened for even longer if you did go the full 3 hours, LOL. Definitely better guests for interview than I'd ever be. ;-)

The controls in cmus are laid out like a traditional VCR/tape-player from left-to-right in the bottom corner of a traditional QWERTY keyboard:

x=play ▶️
c=pause ⏯️

b=next ⏭️

I can't say it helps me remember *much*, but at least that's the reasoning behind the non-mnemonic keys.

Ken, I flagged the show using the supplied,
is flagged as Explicit " switch which is provided on the website. It seems I don't understand the difference in what your requesting and this switch for Explicit content. Offense is in the eye's of the beholder. Frankly, anyone can be 'offended' by anything Ken. The term offended is highly subjective and easily pulled.
If you feel this show is too much of a burden for you then by all means, delete the show. If however you want to keep the show to use as an example to others, then keep the show. Either way, I promise you that "I WILL NOT BE OFFENDED", not offended in any way. It's just a show Ken... :}

I thought HPR was "dedicated to sharing knowledge", so why is this host distorting the truth ?

https://www.factcheck.org/2018/08/putting-frances-consent-issue-into-context/

Q: Did France pass "a law saying having sex with a child is okay"?

A: No. The country already didn’t have a legal consent age. The new law makes it easier to file rape charges against adults who have sex with those 15 or younger.

I added that warning following a complaint from a listener. Our guidelines are "If you feel that your show will be considered inoffensive in every region of the world then you can signal that when you upload the show." This was not done in this case.

Having now listened to the show myself, I want everyone to know that I personally do not in any way endorse or support the opinions in this show.

I am very disappointed with this show. I am sure that HPR would appreciate shows that covered these contentious topics - provided they were handled with care, compassion and without insulting anyone.

I made the title of the show "A Squirrels thoughts about RMS" and the subject line reads "RMS and the subject of freedom" specifically because I wanted to cover RMS's free speech rights being rejected by a commuinity. And wanted to talk about that 'community's' actions in causing damage to Richard Mathew Stallmans person.
The show, should you have listened to it all the way, was not about Pedophilia explicitly but rather about the violation of RMS's rights as a person under the law.

France legalized Pedophillia : see article. France becomes latest EU nation to legalize Pedophilia

https://thetruthrevolution.net/france-passes-pedophile-friendly-law-saying-children-can-consent-to-sex-with-adults/

France follows a similar move in Germany to legalize Pedophillia - Age of consent to be 15 years of age.

Another fun way to learn rust
https://doc.rust-lang.org/stable/rust-by-example/

That was a good call, putting a disclaimer on this episode. There was about 1 minute in that were facts about RMS, then devolved. This was one in which I could not finish, as I am a parent like a lot of us in our little 'hacker space'. I find the subject of pedophilia disgusting and to most, I would imagine, no appropriate here.

Moves to legalize pedophilia in europe? Where did you hear that from, breitbart? I live here, I should have heard about something like that, but so far everything goes in the opposite direction, towards more child protection, and there're even some discussions about raising the age of consent (it's been forteen since the concept existed, which was way before even you were arround).

As for cigarettes and beer on airplanes: your freedom stops where my rights begin, and I feel I do have the right not to be covered in drug gunk and beer (carbonated drink don't work to well in low cabin pressure)

Great show Klaatu.

Fast delivery, accurate, concise, clear, uncluttered, few verbal ticks.

Very few people can deliver a show as fast as I can think.

One of about half a dozen hosts that have me reaching for the play button instead of the delete button

I was truly impressed with this show. This could have been 2 or 3 shows. I appreciate the hard work you put into the show notes. I will be using them someday soon.

One note to other listeners - although you can install kubernetes on a Raspberry Pi 3, it's super slow, so I wouldn't recommend it.

Keep up the great work!

l'm not a sound quality snob, and I'm happy to listen to shows recorded with *unintentionally* not great audio as long as the subject matter is interesting to me. But I think it's another matter to intentionally create bad sound quality. Was it a joke? Just trying to make a point? Or just straight up trolling (which is what I suspect based on some of the other passing comments)? Whatever the answer, chalk up one more comment / vote against the idea of intentionally creating a bad experience for your listeners

Hi,

Loved the show. I started on mainframes in the 1970's where all there was was a teletype or physical terminal. I use X-Windows now, but spend the majority of my time in terminal emulators.

Having spent today in the Linux console on my Debian Testing system debugging a problem caused by the last update, I'm appreciating being back in KDE. The problem was due to multiple incompatible versions of the NVIDIA "legacy" driver lurking in the system it turned out. I wouldn't want to stay in the console though, even with tmux.

Like you I'm a fan of ncurses, and have written a few simple things in my time.

I'm a Vim user and am contemplating moving to Neovim. I've written a few basic extensions in Vimscript but like the look of Neovim's Lua interface.

Finally, you had me going for a moment, calling 'vi' 'six' :-) Having been an ed and ex user in the past on various Unix flavours, I remembered that 'vi' was the abbreviated 'visual' command that gave you the screen mode from ex.

Dave

Thanks for the show! At one point I used emacs on the console because I didn't have enough RAM to run X windows and a compiler at the same time.

Never sat down and got the Linux console to use a good font - these days I run the i3 window manager, so I get a lot of terminal windows, and graphics apps as needed.

If you're looking for an improved sort of ncurses, you could look into the Textual framework.

Figured there would be more comments here about '6'!

Thank you for this great show. I also use CMUS, as it's the only program that doesn't choke on my extremely large music library that I have on an NFS mount. I will be trying out most, and I encourage you to try out ranger!

I updated the script to work with 'most' wonky file names:

https://github.com/freeload101/SCRIPTS/blob/master/Bash/Stream_to_Text_with_Keywords.sh

Wow... I didn't think people like you really existed! Mad props ! Me 4 days ago would have asked you about playing music though a SSH tunnel? but I just switched to PlexAmp for music because my wife uses Subsonic too. I think Subsonic is dying...Another thing is I really enjoy the highlighting in my windows MobaXterm terminal. I have tried a few times to get my entire terminal setup with syntax highlighting and keyword stuff like Moba does but its app specific ... so for example in Vi I can have nice colors then I leave the terminal and I get B/W .. What I want is everything everywhere highlighted like :


* warning messages,error,not,info,complete,OK, IP address,commandline switches ( example ) https://mobaxterm.mobatek.net/img/moba/features/feature-syntax-highlighting.png
* syntax highlighting (without having to name it .bash or .sh ) so for example if I cat out a binary file and it has random scripting or programing in it .. maybe it (detects) python and highlights that …

Anyway great stuff keep fighting the good fight!

I'm glad you enjoyed it. It takes me back too. There are more to come.

Thank you, Ahuka. This brought back memories of working with PCs back in the '80s. Fun times.

Keep up the awesome episodes.

Martin's volume is again/still way too low. It's a PITA to change the volume when speakers change.

This looks pretty great. I just installed ranger and love it already. Thanks for calling attention to ranger, etc. I'm still digging in, but so far so awesome!

Used this today

Great to hear you talk about languages the way that you do. You give a lot of context without a lot of lingo. Looking forward to the next episode.

Lisp: Everything is a list.
Unix: Everything is a file.
Ruby: Everything is an object.
Haskell: Everything is a function.
Rust: EVERYTHING IS AN ERROR!

I have been considering learning some Rust, and this has given me the nudge needed to give it a try.

Looking forward to "Hello World" episode.

Thank you for sharing episodes like these. Not only is the information you present valuable, but sharing your thought process helps provide context, as well as a launch point for others to build on.

I encourage you to keep it up, and start using git to manage and share your code and comments.

PS. I still dispise markdown. :)

Welcome and thank you for sharing. I remember building gates from transistors and then more complex logic circuits from only NAND gates. Those exercises help you to break complex problems down into more simple steps and are valuable in any technical career, especially information technology and security.

I look forward to your future posts.

Thanks for the feedback. There were clicks in there that prevented the normalization from working.

We fixed it manually.

Cannot hear in Mobile

So much about this 'pandemic' has been very questionable. The Scientific Method demands observations from various perspectives. That hasn't happened this time: anyone deviating from the politically-correct narrative was ignored, called names, or shouted down. Coercion, bribery and threats to get 'the jab' are suspect. Where were directions on prevention and treatments? CoGo mentions Vitamin D. This parallels my findings on prevention; zinc also turns up in my research. Big pharma is making big dollars on this event. And as mentioned in this episode, an even more nefarious agenda may be happening than mere $ profit. I heard it said that America is suffering from a lack of conspiracy theories! This is because most of what was initially called conspiracy theory has mostly become truth recently! So yes: critical thinking and research are required in our unusual times. Thank you CoGo.

Thank you for this beneficial information about COVID and the benefits of Vitamin D3

Hi, thanks for the interesting podcast. I actually thought of doing this as well. Can I ask why you picked CEPH instead of Gluster? I think Gluster has an ARM port (but I don't know if it works on Raspberry Pi).

You said something to the effect of me having a "teacherly manner", and that may be the result of my 20 years teaching at the university level. I loved the teaching part, but I hated the paperwork, and especially disliked to low pay. In the U.S. at least teaching is not valued at all, so I left academia to become an IT Project Manager, which is the main reason I can enjoy my retirement now.

Dude, these stories are fantastic. Please keep them coming. While the average listener may not appreciate each and every aspect, along with the technical details, they read (listen) more like an adventure than a resume...

I appreciate this episode, regardless of your view critical thinking is key (for COVID and everything else in life). Great information that I hope will make people think and possibly do some research of their own.

Thanks Trey,

Glad you found the show useful. I sometimes wonder if I'm overdoing the detail, but I enjoy getting into the intricacies of stuff and like to share what I find.

I'm planning Bash Tips episode 22 at the moment, so it should be out before too long.

Dave

Hopefully this will spur some interesting discussions, and maybe further shows.

Thank you for sharing.

Thanks b-yeezi,

Glad you enjoyed the show. I hope you find coproc a useful thing. An HPR show on your experiences would be very welcome I'm sure!

Dave

Thank you for the detailed explanations in this episode. I was completely unfamiliar with coproc before listening. Now I have something new to play with, and am learning something new.

Looking forward to the next bash episode.

Thank you, Dave, for this great show. I will be definitely using coproc in the near future.

Hi Jan,

I checked all the files and I can't find anything odd.

http://hackerpublicradio.org/eps/hpr3410/hpr3410.png

Can you give me more information please.

Thanks

Ken.

I don't know what problem you found with the MP3 file, but it was not on the original. I upload a FLAC file to HPR, which is then converted into other formats for downloading. I subscribe to the OGG feed, and just listened to the show on that feed, and there was no problem. So either there was a glitch in the conversion to MP3, or you had some issue with the download.

This was super interesting. I have to admit I had one of Ken Fallon's thoughts (which he expressed in the community news covering April) - what happens if someone hosting a DNS server in the opennic group returns authoritative results for a name that ICANN should be responsible for - as an example, imagine someone else returns authoritative results for your bank's or doctor's URL.

Simple and elegant, use what you have! I always love listening to your episodes! I used stainless hose clamps on my 2005 Tacoma catalytic converter heat shield, as I was not so fortunate to have a bolted on one. So far they have lasted 5 years in case your lids meet an untimely demise.

Many thanks for this really informative show. :-)

The mp3 seems to bee some what broken.

Ultimately klaatu is the person who got this going. This material was on my web site for over 20 years when he asked to use it for Opensource.com. That got me to ask Ken if he thought HPR would like it. But I guess it shows the value of having your own web sites and controlling your own content.

Thank you for sharing this info. It is so much fun learning the history and challenges we take for granted behind today's technology.

It reminds me of the PBS 3 part documentary "Triumph of the Nerds"

Keep up the awesome work.

Trey

Great show. I like humble bundle for my books because I can use them on any device. Freedom seems to be hard work these days; we have to invest time researching ever purchase because of greedy companies.

Hi Operat0r

Really enjoyed this show. I was particularly interested in your references to gaining physical access to sites using social engineering. In England 40 years ago we used the term "blagging" and my late father was an expert at it. He was in the electrical engineering business and would almost routinely attend conferences and other events for which he had not paid the required fee. His secret was, as he put it, "to look like you have every right to be there", and if you can carry that off everything else drops into place.

Bear in mind that in those days tickets were paper rather than electronic, so a name "missed" from the official list could not be easily verified. Organisers would often apologise for their apparent shortcomings and make sure he got a good seat, freebies and even a free ticket for a forthcoming event.

An episode dedicated to this often overlooked and rare skill could be particularly popular - as long as listeners don't get too inspired and wind up behind bars!

As anyone who has listened to my shows knows I take licensing very seriously. My own view is that if your objective is to expand the free software ecosystem, use the GPL. If your objective is to promote proprietary software, use one of the unrestrictive licenses like MIT or BSD

I'm glad you are finding this helpful. I can recall a time when I was totally confused about GIMP, and would look for some other program to use. Then I decided to dig in and figure it out, and now I wonder why more people don't use GIMP since it is so powerful. But like all powerful tools, it does take time to learn.

Thanks for your series on GIMP, I've always found it hard to use and I think this is going to clear up some of my issues. In this episode - I'm thankful to learn that layers have "modes", I didn't know that. I think that's my main problem with GIMP - it has functionality I don't know about, and sometimes I end up in these other modes and all the commands do unexpected-to-me things in those modes. So now I know to watch out for these layer modes. I'll have to try it out!

In the interest of fairness and balance the rms-support-letter started one day after rms-open-letter. On 2021-04-01 when rms-open-letter stopped accepting more signatures, rms-support-letter had 5051 signatures [1], compared to 3005 sigantures on rms-open-letter [2].

[1]: http://web.archive.org/web/20210401173629/https://rms-support-letter.github.io/
[2]: http://web.archive.org/web/20210401173734/https://rms-open-letter.github.io/

In the interest of fairness and balance the rms-open-letter gained 3004 signatories and stopped accepting more after just Eight Days. The rms-support-letter has only garnered 6800 signatures while still accepting signatories over four and a half months later. You also forgot to mention the 61 organizations that are party to the rms-open-letter.

I always love hearing people's war stories from security. If you have more, please send them in.

Thanks for a great episode - needless to say the audio is great : -) also the topic is interesting and useful. I'm just coming back to the podcasts and listening to some older shows.

Re: avoiding sibilant and popping sounds - and "angling the mic" - do we move the mic 20 degrees off to the side - or vertically? Do we move the mic position in 3d space or do we just keep it in the same position but angle it's direction 20 degrees vertically/horizontally?

Thanks for the episode. Much appreciated.

Sorry but running the water while recording is a real F-U to your audience. I hope we will never be subjected to another HPR episode that does that. One was way too many IMO.

Great show, klaatu! In my previous career as a Project Manager working with big data systems, XML was important for data transfer. For example, in the automitve industry the major manufacturers would insist that suppliers use XML to send data (such as invoices; important!). And in health care it is useful for sending health data.

Also, you mentioned DocBook, and I seem to recall seeing you give a presentation on that, and I think it was at Indiana LinuxFest, but if not, probably Ohio LinuxFest. All good stuff.

The number of signatories of the "open letter" is not five or six figures as mentioned in the episode. It is 3004. By contrast, a letter supporting Richard Stallman (https://rms-support-letter.github.io/) gained 6800 signatures. If the FSFE thinks the matter of right or wrong simply depends on how many people are made uncomfortable, it should withdraw its statement with unsubstantiated claims, as there are more people made uncomfortable by the lynch mob than by Richard Stallman.

See also https://stallmansupport.org/ for a comprehensive account and context of the drama.

Hi Dave, oops. I think I have a habit of doing this sort of thing. I can only apologise to yourself and to any potential listener. I’m glad you managed to solve the mystery in the end and to explain it so eloquently. If only I had said something similar in my episode. Must remember in future to engage the brain before engaging the mouth :)

All the best MrX

It was a lot of fun to listen to how you worked your way through the different exploits. I am looking forward to more.

Hi MrX,

Excuse the ignorance, but I hadn't appreciated:
(a) what a heat shield is, and
(b) what problem was being solved!

So I have found out that a heat shield protects parts of the underside of a car from the heat of the exhaust pipe(s). It's a formed sheet of metal that is bolted to the underside of the car.

The problem was that the mounting holes in the metal sheet had corroded and become larger than the bolts and washers holding it on, leading to nasty rattling. The metal tin lids with holes drilled in them act as giant washers, holding the shield on again and preventing rattling!

I realise that this was a great hack - now I understand it!

As someone who only occasionally uses XML and other data languages like JSON, your episodes on both topics were very helpful.

It is also encouraging to know that there is someone else out there who dispises markdown as much as I do.

Keep up the great episodes.

I had to install an xml config file on a bunch of servers.
The xml was the same for every server except the hostname had to be added to a specific field.

My first thought was to use sed, but anyone who has tried parsing xml with regex knows just how far I got.

Searching for something like sed that understood xml tags led me to xmlstarlet.
Here is the command I used to add the hostname of the server to the xml path "info/host-id":

xmlstarlet ed --inplace -u info/host-id -v `hostname -f` /path/to/info.xml

I'm glad you enjoyed this trip down memory lane. I'm basically releasing the DOS series shows about every four weeks or so, alternating with my GIMP shows.

Really enjoyed this episode. The mixing of computer and personal history was great. Can't wait for the next podcast.

So free speech is ok unless the FSFE descides its not ok. Except for RMS's quircky behaviour he was never accused of doing anything illegal, he was merely excersing his right, endowed by our Creator, of free speech. His only fail was not realizing that the thought police had invaded the FSF. Down with Big Brother.

I love OpenBSD because they produce a secure OS. They also produce the whole OS. You will never see the lead kernel developer at OpenBSD insert a patch for code which was developed by the NSA into the kernel,,,, THEN,,, only withdraw that patch after the entire community forces him to do so..... ...
INTEGRITY,,, SECURITY,,,, CODE CORRECTNESS,,,

Forgot to mention: you should not have to pay that much for a decent pair of shoes. A much more affordable option is Converse Chuck Taylor high tops. Those are the shoes I wore until I got my first pair of Vans high tops. The Chuck Taylors have excellent grip on the board, though they don't have any ankle padding. If you lace em up nice and tight you get good support against turning your ankle, but they won't protect you if your board bangs into your ankle. The Vans high tops are excellent in every respect. I think I got a pair for about $50 several years ago but maybe they cost more now.

I LOVED this episode! Props to you for learning this as an adult, that's really cool. It was wonderful hearing about the sensation of euphoria you felt when you first did various maneuvers. It's easy for me to forget when this feels like because it happened so long ago for me. I was a competitive skateboarder on halfpipes in the 80s and have a ton of experience, so if you ever need a human being to talk through any of this with, hit me up. It will be fun for me.

Glad to hear you will be getting some safety equipment, but you did not mention one of the most important safety items, a pair of wrist guards. Most of the time when people fall they put their hands out to catch themselves, and it's very easy to break a wrist this way. Get yourself some good wrist guards because because you're going to need your hands.

Have fun and be safe!

Fonts were a problem for LaTeX in the early days, because Mr. Knuth invented his own (high quality) system to describe fonts.
Later (with PDFlatex, I guess) it became possible to use PostScript fonts directly.
But PS fonts are expensive, and on Windows PostScript fonts were never really used widely.
And then Microsoft "invented" TrueType fonts...

With ubiquitous cheap (and not always high quality) TTFs there was a growing need to use TTF in LaTeX: It seems like pdflatex can make use of fonts in the TTF format, but I have not tried it myself.

TODAY luatex/lualatex can not only use TTF but also the even newer OTF fonts with very little problems. It works, but ...

The goal of (La)TeX was to produce HIGH QUALITY documents, that's why the default is EXTREMELY high quality and changing things is hard.
With Microsoft products it is the rule to produce VERY LOW QUALITY documents and it is easy to change things to "comic sans" or worse...

Well, with luatex I now can take part in the low quality document revolution. ;-)

that was..something

I've been away from HPR for ages but checked back in this morning and found this show about ebooks. Loved it, and thanks for the mentions. The discussion about page numbers prompted me to look into the issue because it's something that's bugged me for a long time. I was pretty sure there was support for specifying page numbers in the EPUB3 standard, but I've never gotten into the weeds and figured it out. For fiction it doesn't really matter, but as you discuss, page numbers from the physical books are still pretty important in academia where we are expected to cite our sources. I took a couple of hours this evening and learned how to embed page numbers, and tomorrow I'll record a response episode to share how it works. There's good news and bad news involved...

Perfect time for:
```
$ sudo apt-mark hold audacity; sudo apt-mark showhold
```

https://hackerpublicradio.org/eps.php?id=1756

I think I'll record a follow up episode as well.

There is a limit on the about of text you can put in this box - endorsed by the maxlength="2000" in HTML.

There is also a limit that triggers error "cd57ab4d7b77a131ed3deb441bd93dcd" when the server sees that the string length is greater than 2000.

You would think that they would be the same, but they are not due to the amount of data required to encode characters. maxlength counts the number of characters, while strlen() is actual data passed. So if you include a "Smart Quote" it takes double the space of a normal quote.

$ echo '"' > double-quote.txt
$ echo '“' > double-curley-quote.txt

$ ls -altr double-curley-quote.txt double-quote.txt | awk '{print $NF, $5}'
double-quote.txt 2
double-curley-quote.txt 4
-rw-rw-r--. 1 ken ken 4 Jul 6 15:23 double-curley-quote.txt
-rw-rw-r--. 1 ken ken 2 Jul 6 15:23 double-quote.txt

Thank you for your positive feedback, and welcome to the Ham Radio community. Looking forward to your podcasts about it, and now I may need to do some myself.

Trey

Hi Porkchop,

I will be adding the Layer 8 podcast to my list. Thanks for the feedback.

Trey

Greetings

In my comment on the Terminal Journey part 1 I wrote that I had to split my comment because I got an error when I tried to send it in one piece.

Your reply in this here installment was that postings are limited in length. But that is *not* the problem I had. Yes, I did reach the limit, and I could type no farther. So I fixed my sentences to shorten the post by a little bit and then clicked on Send. But I got an actual error page. So I cut my text in half and then it submitted just fine. I suspect a bug in the form checker or even the backend.

I do realise there is enough stuff in my head for several shows. I’m working on that concept. :)

I found this discussion fascinating. I also noted that Linus had mentioned the possibility of using Rust for the Linux kernel, and that is not something you hear every day. If some talented programmer out in HPR land wanted to do a series on programming in Rust, I think it would be a big hit.

I think that those interested in the shows mentioned may also enjoy "The Layer 8 Podcast". It is made by Layer8Conference and each episode features a different person with OSInt ties or experiences and they share stories and talk about how they got into the field. It is more entertainment rather than education centered, so someone not familiar with the field can enjoy it and get a better understanding of what OSInt and redteaming are.

(I had to split my comment in two parts because I was getting an error if I did it in one post.)

About bash keyboard shortcuts:
It is not a default setting in most distros, but I think it was in mine when I started with linux, and now I can't live without it. It allows to type a few characters and then, with the page up/down keys, page through all history entries that start with those characters you typed.
For that, put the following into /etc/inputrc or ~/.inputrc:
"e[5~": history-search-backward
"e[6~": history-search-forward

Regarding grep:
This comes from the g command of the ed editor, IIRC. "g" means "do the following command globally on the file" (vim has the :g command which does exactly that), "re" is the command to run and means "match with regular expression", and "p" means "if it matches, simply print the line".

PS.: it is unnecessary to touch a file if you write something to it right after (unless you use the result value of touch for error checking).

Happy vimming.

Hey some guy,

Regarding your surprise about pwd: I don't know the actual history, your assumption of a minimal prompt might be true. However, pwd is also very handy for scripting. Bear in mind that scripts don't have a prompt. ;-)

Pretend you are in directory A, and the script is in directory B. So in the terminal you enter B/script to run it. Now within that script, the variable $0 contains that calling string, i.e. B/script. But if you call pwd in that script, it returns A(!). So if you use ./ as path for your dump files, that means that the file will be created at your pwd.

I often write quick-n-dirty scripts for one-off tasks and they tend to use relative paths for simplicity. In such cases I use the following line at the start of the script:
cd "$(dirname "$0")"
This changes the script's current directory to where it is actually located. The quotes are there to handle spaces in path names and they are a good habit to acquire. (I'm kind of a language purist and don't like filenames riddled with underscores. I find them hard to read and hard to work with.)

I loved listening to your talk - as a long-time debian-based distro user I learned some things about apt - thank you - plus the recording was well done (good sound levels, clear, no background noise) and you explain things really well. Thanks! Having the show notes is an extra nice bonus.

listening to this reminded me that I never actually listened to the interview with ken's isp!

A fine show with good audio, as have been all your shows.

I enjoyed the clear presentation. Always like hearing different ways to use the command line.

Thanks

Thank you all for the encouragement and kind words. I'll try to provide more shows on this and other topics. Has anyone had any issues with the sound quality or volume for the episode? Just a QA. check.

I do really enjoy hearing the New Year's Eve shows, but this one was 282 minutes long! That isi most of the way to 5 hours. I'd have divided this into 4 shows, each of which would be a bit over an hour.

Long time linux user, but still learning.
I will definitely go back and listen again.

Two packages you might try are nnn and ranger, which are terminal application file managers. They both have good uses, just a different approach and keybindings.

Look forward hearing more.

I have been using various flavors of *nix since the '80s, and I am still learning things. Your detailed and careful explanations are great for a beginner and even interesting to folks like me.

Don't worry about being new. You are learning methodically and are sharing what you learn with others. That is ALWAYS to be commended. Thank you!

Wonderful show. It was an absolute delight to hear your command-line adventure. If there is one thing I have learned about the command-line in my years of computing, it is that there is always more to learn about the command-line. :)

Long time linux user, I but can fully sympathise with much of SGOTI's experience, seems to be a similar pattern in how many of us learn to use the command line.

Really well explained though, will make excellent listening for anyone new to the linux command line who finds it 'scary'.

Good stuff man, look forward to hearing more.

While I am still using a headset microphone and planning to get a good dynamic mic soon, I tried to apply some subtle EQ enhancements to tm latest HPR recording, based on your recommendations in this episode. It is scheduled to air at the end of June (hpr3368).

Keep up the awesome work!

I did a bit of searching and found that SAO = Smithsonian Astrophysical Observatory

There's a Wikipedia page at https://en.wikipedia.org/wiki/Smithsonian_Astrophysical_Observatory

The comment from cagey is a show all in its own right! I'd love to hear more about life as a grad student doing this kind of stuff :-)

Could you add the names and contact pages for the participants as a comment please.

Hi o9l. A few months late, but welcome.
Life has a way of getting away from us.

Look forward to your next show, and don't
worry too much about how you sound.

Thanks for continuing this series.
The samples of type of equalization were enlightening.

Also there are now no crickets (from Urandom oggcast).

Interesting show! I was a grad student in Arizona working with the gamma-ray group at SAO's Whipple Observatory (just south of Tucson). My first task was to develop a tracking system for the 10m Atmospheric Cherenkov Telescope. We used Forth running on a Z-80 daughter board hosted by an Apple II. This same hardware was used to control a 24" telescope. That system was developed by a fellow who had worked for SAO's Satellite Tracking Program. In fact, several other staff members at Whipple had traveled the planet installing, operating and maintaining the Baker-Nunn cameras used to photograph satellites and determine their orbital elements.

The amusing thing is that a couple of years after I graduated they replaced the Apple II with a PC and tried to reverse engineer the Forth code. Given that the tracking code wasn't all that complicated this was sheer insanity. My experience with Forth is that even your own code became rapidly inscrutable. Probably a reflection of my coding acumen at the time rather than Forth intself.

Listening to this I have remembered what I was complaining about in the show. I was referring to podcasts (and presumably radio shows) like "This American Life" which "interview" people but "translate" what they are saying over the top of them.

This is a "style" that many broadcasters seem to have adopted. Many of the BBC podcasts I have stopped listening to do this too. I find it distracting and insulting to the interviewee. It seems to be an example of media people reinterpreting what experts are saying in many cases, and we know how much misinformation comes from this practice.

If this is "professional" I don't want to have anything to do with it!

I have been wanting to comment about this for some time.
The quality of the audio is somewhat important but not a qualifier.
But what I at least WANT is the level of volume to be normalised at 95%. Its hard to hear in a noisy environment like a car or places with background noise.
This is easy for a submitted sample. Run all input/submits through a normaliser/compressor.
Volume checks in mumble/radio should also normalise.

Hi Dave sorry for taking a bit of time to reply. I noticed the comment flag up in my RSS reader and then promptly forgot all about it as things have been crazy busy here. I only remembered thanks to a gentle prod by Dave Morriss.

Glad you enjoyed the show. By coincidence I turned my HF set on just last week something I hadn’t done for a good long while. I must admit to being a bit rusty with the latest rules and regulations but I seem to remember that certainly here in the UK you are encouraged to use the NATO Phonetic Alphabet. I’ve certainly heard various stations using different Phonetics. Perhaps they think it’s easier to hear under noisy conditions or perhaps they just like the sound of it. Personally I just stick with the NATO Phonetic Alphabet.

Dave mentioned you recently became an Amateur, so many congratulations. I’m sure you’ll have lots of fun with the hobby as there are so many directions it can take you.

All the best

MrX

Having just joined the ranks of Amateur Radio users, it made sense for me to look for HPR episodes relating to Amateur Radio.

I loved this episode, very interesting listening to conversations on the 40m band... real hard-core users on 7MHz!

I did notice that the German station DF2BO wasn't using the NATO Phonetic Alphabet, is this a common occurrence?

It is the most enjoyable article that I have ever read (with the possible exception of those that might have been more enjoyable).

An excellent dramatic reading as well.


Cheers!

I would like to thank everyone who joined in the podcast. Without people coming on and talking there would be no podcast.

Thank you, and I look forward to talking to everyone again next new years

I would like to thank Pokey for coming up with the idea for the new years show. Without this show I don't think I would have ever had the courage to start podcasting

Thank you

I would like to thank the members of the urandom podcast for having me and kwisher on to promote the new years show.


Thank you

I would like to thank Dan from tllts for playing the promo for the new years show in the tllts podcast.

Thank you

I would like to thank the entire hacker public radio community for participating in the new years show.

Thanks

I would like to thank Ken Fallon for his job recording this podcast. It was because of his fine recording of the stream that this podcast happened.

Thank you

I would like to thank kwisher for running the stream for the new years show.


Thanks

I would like to thank Dave Morris for fixing the show notes.

Thanks Dave

Looking forward to the next episodes in this series.

If you really want to fly, you can turn the pandas series to numpy arrays first. For you example, it got twice as 2x faster than regular `np.select`.

Example:
```
cond_list = [df['Score'].values >= 9,
((df['Score'].values >= 8) & (df['Score'].values < 9)),
((df['Score'].values >= 7) & (df['Score'].values < 8)),
((df['Score'].values >= 6) & (df['Score'].values < 7)),
((df['Score'].values >= 5) & (df['Score'].values < 6)),
((df['Score'].values >= 4) & (df['Score'].values < 5))]

%timeit np.select(cond_list, choice_list, default='Require Activation')
23.5 µs ± 1.74 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
```

Thanks for another great show. I look forward to your next one.

As to your use of `pd.apply` in lieu of `np.select`, here's my 2 cents:

Apply is more readable in most cases, but select is more performant. When performance matters, or when the dataset is very large, you might want to use `np.select`. For instance, when using `np.select` on your example here, the output was 10x faster on my PC.

```
%timeit df.apply(Scorelevel, axis=1)

448 µs ± 2.88 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
```

```
%timeit np.select(cond_list, choice_list, default='Require Activation')

55.6 µs ± 440 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
```

In many cases, the readability can trump the need for speed, but just wanted to give a counter-point.

What if an updated app isn't compatible with current nextcloud version ?

I'm just commenting to say that this manifesto and subsequent show makes an excellent point. The free software community as it stands has good and as discussed well guarded principles with no compromise. While this is admirable it is also what is killing the movement.

Like language all movements must eventually morph or evolve over time or they die off, it is completely acceptable to maintain a core set of tenets of course, but having a figurehead who uses the internet in bizarre and arcane ways makes free software like more a paranoid nest of conspiracy theorists than it does to make technological progress by freeing the user from the constraints of mega corporations.

Free software is inevitably political but the mocking and jeering of people who still use proprietary software scared off companies and created the open source movement, which if anything made it easier for mega corporations to profit off of the collectivised free labour of programmers who cared enough to donate their time.

To me the free software stalwarts were the progenitors of their own worst enemy, which is open source. They allowed it to happen themselves and fostered the likes of Google and Facebook. The FSF concentrates too much on acting like a single-state communist party with it's attention focused on creating a cult of personality around Stallman.

I agree the roots of the movement today should reflect more social needs, creating software for the good of the people even if that makes software socialist.

It is great to hear about the podcasts you follow. I recognize many of them as shows I used to follow, though frankly since I retired I have been putting my energy into other matters. I'm turning 70 in a few months and have other priorities now.

Well now I have to do a reply episode on my favourite infosec podcasts...

Glad to hear it, clacke. I look forward to your shows.

There has been a lot of bubbling out there in the free software world since a decade or more and it's recently coming to the surface. I have two more of these readings coming out as soon as I have put together the background material.

Sneak peek:
- https://techautonomy.org/ (2020)
- https://opensourcedesign.net/manifesto/ (2014)

How I listen to the Twit network podcasts. Many MP3 players and podcast apps on your phone have us sleep timer.
Getting a easy chair, lean it all way back. Cover up nice and cozy. Turn your volume down just until just before you can not understand what they're talking about. Set the sleep timer for about 12 minutes. My podcasting app will turn the volume down even more the last 30 seconds so it's not an abrupt shut off. Now you're ready for the best nap you've had in a long time. My MP3 player is an old moto E3.

The Urandom Podcast, spawning HPR episodes and shameless promotion simultaneously since 2021. Seriously though, great job. I have a MUCH better understanding of DNS66 after listening to this. Good job.

I always thought that artificial intelligence is misleading. Artificial programming would better describe what's going on.

My great thanks to Clacke for posting this. I think this manifesto is a great contribution to the discussion of free software. If free software is not respecting of people, what good is it?

Good to know this worked for you as well. I think original youtube post was meant for backup of a ton of games. In most cases, this will not be needed because the games don't take much room anyways.

What threw me for a loop was that there is a sdcard - vfat that goes into the front. Then there is a usbstick that goes into the back.

Other than that worked as described.

Thanks for this. I knew there were people in FOSS who felt the way I do, but this is the first I am hearing about a public declaration.

I have been a a GNU/Linux user for around 2.5 year now and I have been a fan of RMS for much of that time. I have heard about people thinking Stallman is kind of weird, but chalked it up to differences in political opinion, or his refusal to meet people where they are. This is my first time hearing about some of his gross opinions.
As a leader in the free software movement, he should NOT be turning people away with these opinions. To be perfectly clear, I stand with the survivors of sexual assault, and I stand with anyone who has put their trust in the supervision of an adult who would betray that trust for sexual gratification.
The GNU/Linux community is a better place when we treat each other respectfully and with compassion. We don't need any one person in our community as much as we need the community itself.

Very Clever
https://xkcd.com/1356/

Nobody is saying Stallman can't say having "consensual" sex with a 12 year old doesn't harm the kid. But nobody who isn't actually brain damaged should defend it nor is anybody actually forced to associate with him because of "free speech". It doesn't violate any free speech value to say you can believe whatever despicable things you want, you can advocate for any despicable thing you want, but nobody else is obligated to support you or be allied with you. It's not cancel culture. It's being responsible for the ignorance he spews culture.

As for how the FSF is damaged for it, look at how many organizations have pulled their support. Nobody is bigger than an organization unless the organization allows itself to be subsumed to a cult of personality. It rarely works out well. Part of the reason that the FSF is useless is because they have allowed themselves to be so beholden to a useless repugnant toad like Stallman who pushes a majority of people away. If you want an idea to grow, it helps not to be led by somebody who intentionally spews reprehensible nonsense that pushes everybody else away. Stallman is a toxic excuse for a human being. You want Floss to have a chance to grow? Don't let it be led by a guy who intentionally says things that are considered morally repugnant by the majority of the public.

Few of us are so synomymous with the organisation we work for that any controversial remarks we make in public are likely to do lasting damage to the reputation of said organisation - especially if we were to subsequently resign and remain silent afterwards. That is not the case with RMS with regards to the FSF. He will forever be associated with the free software movement and, by implication, the FSF.

On that basis engineering his resignation on the strength of his comments on social and political issues did nothing to protect the reputation of the free software movement. All it achieved was to salve the consciences of the other FSF board members. How damaged was the free software movement anyway?

Most people outside the FLOSS world have never heard of RMS so his sometimes distasteful, but sometimes thought-provoking views would have no bearing on their decisions to adopt open source software.

People in the FLOSS world know RMS for his eccentricities, along with his visionary genius. I suspect that while many publicly feign shock at his outbursts, for most it is just "RMS being RMS" followed by an attempt to get any images conjured up by some of his ideas out of their heads.

If the FSF fundamentally stands for anything it is freedom, so to sideline somebody for exercising their right to personal opinions and free speech seems a bit incongruous. Given that getting rid of RMS was never going to distance the FSF from him, they would have been better to have taken the view - even in the form of public statements if necessary - that other FSF board members abhor some of his views on non-technical matters but totally support his right to hold and express those views. In these days of "cancel culture" when people are dismissed from jobs or prevented from speaking in public for fear of what they might say it would have been a refreshing change to see an organisation defending the right to free speech instead of just taking the path of least resistance.

Hi Reto,

The TTS (text to speech) engine used is espeak, and is available on many linux distros. It is relied upon by thousands with visual impairments, and those with reading disabilities - myself included. You must be new to HPR as we have been using espeak for years, and were only recently able to negotiate a contract with Lyn (text2wave/festival) after her noncompete-agreements from the lottalinuxlinks.com podcast expired ;-).

Unfortunately the site you posted left me wanting when it came to hearing the other side of the story. But as you say it can be difficult to find accurate information on the Internet, especially one that is reliable and trustworthy. I would always suggest to go to the source of truth first. In this case it's best to start with Richard Stallman and the Free Software Foundation (FSF) itself. Sure enough on the main FSF page there are two articles "Statement of FSF board on election of Richard Stallman"[1] and another "RMS addresses the free software community"[2]

We have interviewed RMS on episode hpr0271[3] and hpr1116[4], so it would be great to get him on again to discuss this. Can you reach out to him and/or the FSF to see if they would be interested in recording another interview ? Be sure to mention we only use Free Software for the recording [5], and that we can release it under the CC-BY-NC-SA[6] if desired. I think the whole "not release in mp3" thing is no longer a problem, but if it is we can deal with that as well.

In the meantime I will put together a similar show to this using their statements, and post it as a counter point show.

Hi,

First of all this TTS (text to speech) voice is terrible I can hardly understand it, the one used by HPR is much better.

Secondly, if I hear some information where I get the impression it is totally on one side, I want to hear the other side in order to build my opinon.
Took me 20 minutes to find it, the other side, looks like the internet tries to hide it: https://debian.community/molly-de-blanc-arrest-and-prosecution-for-cyberbullying/

Have you seen the episode of "The Orville" where your reputation and punishment is based on public opinion rather than from a court? It was scary!
While this was fiction, does it now become reality and do you support this?

Just some thoughts on what is going on here.

Very interesting episode. I didn't know about this technique. I guess there is an irony in that by publishing this spam bot makers might eventually get around to implementing ways to defeat this in the long run.

I would love a followup episode on this, how it worked out over time and such.

Keep up the good fight and thanks for a good episode.

Hi brian-in-ohio,

The only requirement for posting to HPR is that the show is "of interest to Hackers". (And isn't spam, and meets the licensing terms). There is no requirement to be personally identified on HPR.

While some contributors like myself use their real names, others like yourself use handles instead. I'm sure most of those who use handles do not do so to hide their identity - but some might.

It's a moot point anyway because we know Bradley M. Kuhn was the author of the show. We don't know who posted it, but I don't particularly care. They could have posted the show under a fake user name and we would never know. There are quite a lot of shows posted that were controversial at the time, and were submitted by a host that never posted again.

I feel that posting under the Anonymous username is more honest. It alerts the HPR community to the lack of implicit trust that comes with a (fake) real name. (It also means less work for the janitors as we don't need to create new users :-) )

In any event, Hacker Public Radio has long supported, and will continue to support anonymous posts, comments and other forms of interactions. We do this for many reasons, not least of which is that freedom of speech is not always without cost.

Ken.

Agree or disagree with RMS, at least we he does not hide his beliefs behind the moniker 'anonymous '.

I routinely encourage people to disable automatic image download for privacy reasons, but never thought of your idea to habitually view emails in plain text. I'm going to do that.

The idea of running rules before spam processing seems obvious after you hear it. My spouse is constantly losing important emails in the junk folder.

I loved hearing the mention of my friend Michael W. Lucas. He is a great writer, and his technical books are are awesome. I used his book on SSH as a resource when I did my shows on that topic. He also writes some pretty good fiction, such as "git-commit murder".

I use "sox" in linux scripts to automate stuff like speeding up audio, removing long periods of silence, etc:

# adjust speed
sox input.wav output.wav tempo [value]

Apparently the term open source was not quite coined at that meeting described in the opensource.com article, people had been using it in a software context (not just the well-known military intelligence context) some time before then:

https://web.archive.org/web/20180315075903/hyperlogos.org/blog/drink/term-Open-Source

/via https://fosstodon.org/@be/105994362194990430

An excellent show sir.
Someday, I will try and put Slackware 13 on my older chromebook.

I'm canceling this episode you the only valid reason, slurping your drink in my ear at high volume. :)

The one I bought was called Klangtop, which I found on Amazon. I just looked, and now I don't see it, but I see something that looks identical under the name AGPTek. My guess is that they are all manufactured by a Chinese manufacturer as OEMs for various companies.

hey, I was a long-time fan of the Sansa Clip as well and managed to eventually kill both the ones I owned (and had put RockBox on). When I went to look for a 3rd one, they were outlandishly expensive. I couldn't suss out the make/model of the one you switched to.

I really enjoy these shows where people show how they defeat the bad guys. I hope there are more war stories to come.

Well said! I'll never understand why people feel entitled to attack those donating the results of their hard work. If I don't like a piece of free software, I can skip it and support the ones I do.

In the episode you weren't quite sure if there are other MACs for Linux beside SELinux and AppArmor and indeed, there are!

There is Smack which is quite uninteresting as it's just an another label based MAC, similar to SELinux.

To me the interesting one is TOMOYO which started as a pathname based filesystem similar to AppArmor but later started differentiating between applications based on their process invocation history. This means you can apply different policies on say /bin/sh depending on the chain of execution leading to it (kernel -> init -> getty -> login -> sh VS kernel -> init -> sshd -> sh). While this is also possible in AppArmor it is quite a lot more manual work and more difficult to reason about.

TOMOYO also has much nicer tools than either of the more well known MACs. SELinux has given MAC a bad name as being hard and laborious to manage. If instead of SELinux people would be first introduced to TOMOYO they would probably be much more inclined to implement a MAC.

I gather you won't see it, but thank you for the kind words. I look forward to more shows from you.

Hi there,

I’m afraid I may have to dampen your expectations here. These days, the Windows license key (at least the OEM ones, meaning those that are imposed on you when you buy hardware) is usually tied to the hardware, i.e. the BIOS or whatever chip. I don’t think It will be accepted inside a VM.

Your best use for the drive would be to pop it into an external case and use it as mobile storage or as a backup drive. (Or leave it bare if you have a hot-swap adapter) That’s what I did with the HDD that came in my Thinkpad. When that arrived 5 years ago, I only did a short boot-up because I was curious about Windows 10. So I had my first (and for many years only) contact with that. I then swapped the drive out for a 3rd party SSD (also from Crucial) straight away.

Regarding your RAM peculiarity, I’m not sure but it sounds like those missing 2 GB are siphoned off for the internal graphics.

The coffee slurping noises and throat clearing distracts from what is an enjoyable podcast. And, for someone who mentions that HPR is apolitical, you spent a lot of time talking about fascism and cancel culture.

with ffmpg and VLC you can get everything done you need likely...


https://trac.ffmpeg.org/wiki/How%20to%20speed%20up%20/%20slow%20down%20a%20video



ffmpeg -i input.mkv -filter:v "minterpolate='mi_mode=mci:mc_mode=aobmc:vsbmc=1:fps=120'" output.mkv

Yes lynx can be used to upload to HPR. Just tried it and it works fine.

If you are leaving comments and get an error, please email me and I can see what's causing it.

For old or future shows, we have extra checks.

1) A difficult question related to what the P in HPR means.
2) Deselect the "I am a spammer" tick box.
3) Fill in the name of the host (you on this page)
4) And tell us something to prove you are not a spammer.
I'm using "Watch out that Squirrel is running 32 bit" for this one.

Thanks for sharing your thoughts and feelings about bad terms in IT. I've better understood now, what they may cause, so you got me to finally rename the default branches of all Git repositories in my organization I'm responsible for.

I've written an internal blog post about that, linking to this HPR episode. Hope that others will follow my example.

Amazing how many times I've needed to use this.

I didn't know OpenLDAP originally ran on BDB! These days it uses its own LMDB, which has also replaced BDB in many other places.

Turns out, OpenLDAP started using BDB in 2002 and LMDB wasn't ready until 2011. In the middle of the NoSQL boom! :-)

https://en.wikipedia.org/wiki/OpenLDAP

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.

https://en.wikipedia.org/wiki/Redis

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

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.

Martin:

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!

https://www.youtube.com/watch?v=0b_eHBZLM6U

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!

Thanks for the show, for slackware current users, alienbob has packages available here's the link http://www.slackware.com/~alien/slackbuilds/libreoffice/pkg64/current/

https://www.bitchute.com/video/0EYfFZnLAxI/

That was one of the GTTS voices. It is added as part of the show upload processes.

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.

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.

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

Capitalsm is successful as it models natures "kill or be killed" ethic at a conscious level.

In short, YES, your going to get out there and your going to die.
The problem was in allowing China into this "GLOBAL" community, not whether or not your going to hide in your house...

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.

https://en.wikipedia.org/wiki/Blood_type_distribution_by_country

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.

Dave

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.

*Sean Connery voice*

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.

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. :-)

>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 the wonderful series!

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).

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

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

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

Keep up the good work.

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

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

Speaking of the HPR Book Club ...

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

Hi LnB,

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

Just like they do with the HPR Book Club.

Speaking of the Book Club.....

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

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

Thanks again.

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

Hi Gabriel,

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

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

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

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

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

Dave

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

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

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

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

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

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

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

Welcome and thanks for the great first episode.

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

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

Great episode on Mastodon and the various instances.

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

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

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

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,

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
