Mailing List discussions
Policy decisions surrounding HPR are taken by the community as a whole. This
discussion takes place on the Mail List which is open to all HPR listeners and
contributors. The discussions are open and available on the HPR server under
Mailman.
The threaded discussions this month can be found here:
This is the LWN.net community event calendar, where we track
events of interest to people using and developing Linux and free software.

Show transcripts
Transcripts of audio have been generated for shows since December
2022, using the Whisper tool.
Ken Fallon has been working on this project, and has also been
transcribing the older shows from hpr0001 to the present
day. This part of the project is complete.
The transcripts have been attached to each show on the HPR website,
and are in the process of being added on archive.org.

Diving into privacy-aware and offline methods to generate one time passwords

Many services implement 2FA (Two factor authentication) by sending
you a OTP (One Time Password) using an SMS with a random code, but this
forces you to give them your valuable phone number. What alternatives do
exist?
Let's dive into the HOTP,
used by some banks years ago through a physical token and the recent TOTP,
which both let you generate completely offline codes without
using any phone number or any other personal detail. They use the HMAC technique usually
with a SHA-1 one-way hashing function, but other hashing functions can
be used too.

Accessibility,
and Navigating the HPR Web Pages with a Screen Reader
Some time in the last year there has been some discussion on the HPR
mailing list about some of the problems I was having, particularly with
the tags page, on the HPR site.
Here is a show in which you can hear both me and my screen reader, as
I navigate the HPR home page, and then the HPR tags page.
Dave Morriss has made a nice job of fixing the issues I had, and made
the tags page a lot more friendly for blind and visually impaired
users.
It's quite a long podcast, and it took a lot of editing. So most of
the polish wore off by the time I 'finished' it and decided enough was
enough.

Using the Joule Thief to suck energy out of flat batteries

The Joule Thief is a delightfully simple circuit that can light an
LED that requires 2V or more from a battery that is depleted to 1V or
less. There are three components in addition to the battery and LED: an
NPN transistor, a resistor and a double wound inductor. The key thing
about the inductor is that the same core shares two windings but in
opposite directions.
The explanation of how it works is simple enough, as long as you
already understand how inductors and transistors work. In other words,
it isn't simple at all! In short, the double wound inductor and
transistor conspire to generate a transient high voltage spike and so
turn LED on and off so rapidly that the human eye cannot perceive
it.
The idea of such a circuit is approaching its centenary but the name
itself is only around 20 years old. I recommend you check out Big Clive's web site as it was
he who came up with the name "Joule Thief". I also recommend this video in
which he constructs a circuit using some ninja-level soldering
skills.
This episode reports on some updates to the Fediverse that I ran across in May 2022

One of the things I love about the Fediverse is that there is constant activity and development. As I mentioned in the previous report on Bookwyrm, it is not unusual to return to an app a few months later and see new features have been added that make it better. In this report I want to highlight three news stories that I think may be of interest.
Just because you can do a thing, does that mean you should?

Hello Hacker Public Radio fans. This is Trey, and I am throwing this
recording together for several reasons:
The queue of shows is abysmally sparse. There are far more
openings for shows in the next few weeks than there are shows
posted.
This show is a pitiful excuse for why I haven't posted any shows
recently
If you like what you hear on Hacker Public Radio, please express your
gratitude by recording your own show. It doesn't need to be long, or
sound professional, or anything. Introduce yourself and share something
you find interesting.
If you do not like any or all of what you hear on Hacker Public
Radio, then it is the perfect opportunity for you to take a few minutes
and record a short (or long) podcast of your own which "fills the gap"
of what you might feel is needed on HPR.
Alright. Enough preliminaries.
A long time ago, at an undisclosed university far, far away, I took
my first class about Ethics. One of the things I remember most was the
question of "Just because you can do a thing, does that mean you should
do the thing?"
This was applied to many different scenarios - from nation states
building weapons of mass destruction, to authoring computer viruses, and
even to saying what you are thinking at any given moment.
It should quickly become obvious that you should not always do a
thing simply because you can do it. And today, I would like to relate
that to DIY home improvement projects, especially as we work our way up
in years.
For regular listeners, you may recall my series "Everything You
Always Wanted to Knox about PEX" recorded and shared in May through July
of 2022 (hpr3604, hpr3614, hpr3624 & hpr3634). In
this series, I recounted the process of replumbing my home using PEX
with helpful advice for anyone else who wants to try it. What I did not
realize at the time I was doing the project was the toll that doing so
much work overhead, by myself, was taking on my old shoulder joints. It
was only one straw, but a rather significant one, which eventually broke
the camel's back. Or, in my case, resulted in several severe tears in my
rotator cuff and bicep tendon.
Therapy was marginally effective, and surgery was eventually required
to put things back together the way they belonged. My effort to save
money and do the project myself "Because I could" helped lead to
significantly more expenses and more than a year of recovery.
I am not sharing this for sympathy, but rather because I learned
something important. Now that I am getting older, as I decide which
projects I should do myself and which to pay professionals to do, it is
important to factor in the potential impact on my body, my mind and
those around me, even if all goes well.
Just because you can do a thing does not necessarily mean you should
do a thing.
Unless that "Thing" is recording a podcast for HPR. THAT is something
you can and should do.
I made a 'beeing" podcast about Google products, interoperability and their lousy security

I have a discussion about my Android "WIPING" and how it affected my
2 factor authorization with Google. Further I "beein" some more about
Android not being able to authenticate against a known chromebook using
GOOGLE SECURITY, what a "beeing" , "beeing"!!!!
And I also cover Google's lousy support for chromebooks through
Android, not sharing bandwidth via the cell communication channels. I
cover easytether and ask why Google hasn't given chromebooks the same
bandwidth access any Android phone would have??? WHY???
Google is so piggish and stupid that Android and chromebooks are
almost as if they were separate companies who are in competition with
each other instead of two products from the same company.
I also cover the overbearing Android growth via QR codes and programs
like healio.
