September 29, 2025HPR4476: Does AI cause brain damage?
This show has been flagged as Explicit by the host.
Quick-Glance Summary
I walk you through an MIT experiment where 54 EEG-capped volunteers wrote essays three ways: pure brainpower, classic search, and ChatGPT assistance.
Brain-only writers lit up the most neurons and produced the freshest prose; the ChatGPT crowd churned out near-identical essays, remembered little, and racked up what the researchers dub
cognitive debt :
the interest you pay later for outsourcing thought today.
A bonus “switch” round yanked AI away from the LLM devotees (cue face-plant) and finally let the brain-first team play with the toy (they coped fine), proving skills first, tools second.
I spiced the tale with calculator nostalgia, a Belgian med-exam cheating fiasco, and Professor Felienne’s forklift-in-the-gym metaphor to land one mantra: *scaffolds beat shortcuts*.
We peeked at tech “enshittification” once investors demand returns, whispered “open-source” as the escape hatch, and I dared you to try a two-day test—outline solo, draft with AI, revise solo, then check what you still remember.
Net takeaway: keep AI on a leash; let
thinking drive, tools navigate
.
If you think I’m full of digital hot air, record your own rebuttal and prove it.

September 23, 2025 HPR4472: Cheap Yellow Display Project: Introduction to the Cheap Yellow Display
This show has been flagged as Clean by the host.
Hello, again. This is Trey.

Several months ago, I heard Paul Asadoorian mention the Cheap Yellow Display on his podcast,
Paul's Security Weekly
(
https://www.scworld.com/podcast-show/pauls-security-weekly
). I didn't think much of it at the time, but then I heard it referenced again, and again. Then, finally, it was described, and I became interested.

"Cheap Yellow Display" is the term used for the ESP32-2432S028R. Since this is somewhat challenging to say, and to remember, and since the board is yellow, and it can be obtained for as little as $12 USD, it has been given the nickname "Cheap Yellow Display". I will abbreviate this as CYD for the remainder of this episode. It is an
ESP32 (with built in WiFi & Bluetooth) on a development board with one or more USB connectors, a MicroSD slot, a limited selection of GPIO pins, an RGB LED, a speaker, a light sensor, and best of all, a
2.8-inch (71mm) TFT touchscreen LCD display.

The CYD runs on 5 volts DC. I am including some photographs of the CYD in the show notes.

RandomNerdTutorials
has produced a very good writeup about this board on their website (
https://randomnerdtutorials.com/cheap-yellow-display-esp32-2432s028r/
).

Brian Lough (AKA
WitnessMeNow) has been building a community for the CYD on his GitHub site (
https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display
) where he has instructions, examples, tutorials, downloadable tools, and much more.

Beginning back in the 1970s, my father and I built electronics projects together. And I have had a love for doing so ever since. Over the last few years, I have built several Arduino based gadgets on different platforms, including a couple which run on breadboards sitting beside me on my desk (I will share more about one of those later).

A common use for the CYD among hackers is to leverage the built in WiFi & Bluetooth radios to compromise wireless networks or devices. The Marauder project is a prebuilt image which can be loaded directly to the CYD to use it as a wireless hacking tool.
Fr4nkFletcher's Github repository
(
https://github.com/Fr4nkFletcher/ESP32-Marauder-Cheap-Yellow-Display
) is one place where you can download the Marauder tool. There are also video games, clocks, photo slideshows, and more, which have already been coded for you, and are available on the internet for download.

What would you do with a CYD? What could you build? What problem might you solve? What fun project might you come up with?

For myself, the CYD intrigued me, but it did not yet jump out at me as something I had a need for. Yet.

What would change my mind? What would set me on a quest to obtain some of these devices and learn to develop code for them? What problem did I wish to solve?

Tune in again, in a couple weeks, to learn the answers some of these questions and more in my next episode in this HPR series.

September 22, 2025HPR4471: Ti-82 Makes Music and Password Manager
This show has been flagged as Explicit by the host.

The TI-80 is a graphing calculator introduced
by Texas Instruments in 1995 to be
used at a middle school level (grades 6 to 8).
It offered advanced capabilities that had previously only been
available in high-end scientific calculators to
students learning pre-algebra and algebra,
and was designed to be affordable for schools.

September 18, 2025 HPR4469: Disagree With Me - 3 Statements About Life Living
This show has been flagged as Clean by the host.
Hello from Antoine. A show without a script, with 3 bullet points:

1.
It's better to have had 1 million dollars, and spend it all in a bed investment, rather than having had 5 dollars and lose 10 dollars.

In one case, you are not in debt, you can start on zero with a clean mind (the past is only past). In another case, there is a debt, you wasted what you even did not have at first. That's a problem.

Losses happen all the time, in sports for example, and people in general understand. Albeit, when it has to do with family problems, or financial lack of success, there is all kind of malicious judgement for the bad choices of the other one.

2.
A good work is a work where one does what he has to do, in the time he sold to the work.

It's not a matter of being on the desk more time than your colleagues, it's a matter of giving your work capacity for the time agreed in exchange of the payment agreed upon. In one word, honesty. Even if not as a moral value you agree with in a specific case, the obedience is the result of having your mind in the same way your body is going, and that is enjoyment.

3.
Your attitudes show if you have a purpose in what you're doing, or you're taking it with the belly (doing it in a non-vigorous way, without enthusiasm).

If you have a purpose, you are enjoying, because it has a purpose. You, after all! (Not because of big loads of material things, but, simply, purpose. Relations and purpose.)

September 17, 2025 HPR4468: AI Trap and Fix
This show has been flagged as Clean by the host.
Hello, this is your host, Archer72 for another episode of
Hacker Public Radio.
In this episode, I continue to fall for the AI trap.
Here I was, minding my own business, when I was bothered by
the icon only showing a generic icon for the Beeper app.
Now, I'm not saying that Duck.ai is not useful, but be
very careful what you ask for.
It was probably a combination of the early morning, and not
reading completely through the AI suggestions, but I ended
up losing all icons on the Gnome desktop except for a few
like Firefox. I won't leave the problematic command so I
don't trip up the listener, but it involved updating a
desktop database. This in turn left a dash or blank where
the icons should be.
If that wasn't bad enough, it was suggested to reset Gnome
settings, and nothing was as it seemed before. Things that
I had taken for granted were not there. You forget what
custom settings are there when mistakes like this are made.
So the short answer is that the icons directory, located on
my Debian system should be located in
.local/share/icons.
Instead it was in a sub-directory
.local/share/icons/icons
Correcting the directory location solved everything, but I
was still left to reset my custom Gnome keybindings.
• Swap Escape and Caps lock key
I used this because I am a Vim user, and this feels more
natural when I need to hit Escape to change modes.
In Gnome, the setting is under Gnome Tweaks >
Keyboard >
Additional Layout Options >
Swap Esc and Caps Lock Key
As of this show release the current stable version is
Trixie. Gnome Tweaks - Debian Trixie can be installed by sudo apt install gnome-tweaks on any Debian based system.
• Compose key
• Compose key shortcuts
The Compose key is found at Settings >
Keyboard >
Compose
Key. I selected the Menu key, because this is rarely used,
and can still be accessed by the track pad.
• Shortcut to open MPV with a clipboard URL from Youtube
This can be found in Setting >
Keyboard >
View and Customize
Shortcuts >
Custom Shortcuts
Shift+Ctrl+P
Code placed in /usr/local/bin/
#!/bin/bash
## mpv-url
url=`xsel -o -b`
echo $url
mpv $url
Now I can get back to what I started in the first place,
creating a .desktop file for Beeper.
I created a beeper-desktop.desktop file in
`~/.local/share/applications' with the follow contents.
[Desktop Entry]
Name=Beeper Desktop
Exec=/home/mark/AppImages/Beeper-4.1.169.AppImage
Icon=/home/mark/.local/share/icons/beeper.png
Type=Application
Categories=Network;InstantMessaging;
Terminal=false
StartupWMClass=Beeper
The last part of the config file can be found by
xprop | grep WM_CLASS
