I'd previously had a barebones interest in electronics (think: kits with LEDs and buzzers in like 3rd grade), but listening to his discussions and explanations of how these things worked gave me a fairly decent understanding of how some basic electrical principles work.
I also recently watched a video series[1] that explained how microcontrollers (specifically the ATMega328, the one powering the Arduino) work, from a very low level that I've always wondered about. The key part of that series, for me anyway, was getting the chip off of the Arduino PCB and onto a bare breadboard. From there I went and read/skimmed the ATTiny85 datasheet[2] (a very popular "baby brother" chip to the ATMega328) which also helped me understand how these chips do things like PWM on a low level.
I've built one project (a simple PWM dimmer based on a potentiometer) and am working on another (designing a PCB with KiCAD[3] to replace the circuit board for a battery-powered LED lantern, so I can design my own sequencing interface for what happens when you press the singular button), and it has been quite the learning experience, but one I've greatly enjoyed!

[3] This comment is long enough already, but KiCAD is a fantastic piece of FOSS software. It's a full schematic/PCB design suite, and there are plenty of tutorials all across the Internet for it.
I'm on a laptop running Ubuntu, I use Firefox as my browser, and I use 1Password as my password manager. I have both the browser extension and native Linux application installed, and they sync/communicate with each other (so if I unlock the native Linux app, the browser extension also unlocks).
When I open my Amazon.com item in 1Password, it has a helpful link to https://passkeys.directory/details/amazon which tells you clearly, step-by-step how to set up a passkey. Great! I love clear directions.
But when I get to the step when I click the "Set Up" passkey, Firefox gives me an address bar pop-up saying "Touch your security to continue with www.amazon.com".
Huh?
I don't have a security key. My laptop does have a fingerprint reader, which I use to unlock my screensaver (and it's integrated with some KDE keyring thing), so I tried putting my finger on that. Nothing. I opened the 1Password extension. Nothing there, just normal view of my login info. I opened the 1Password native application. Nothing there either.
Maybe it's a Firefox issue, or a Linux issue? So I tried setting it up on my phone (running GrapheneOS and their Chromium-based browser), which has the 1Password app installed. I logged in, and this time got far enough that 1Password brought up a prompt asking "Do you want to save this passkey?" I tapped Yes, and it then immediately told me "Unable to save passkey: For security reasons, 1Password did not save this passkey. The associated URL for this passkey does not match the selected app." So... does that mean 1Password is refusing to touch the passkey because it didn't come from the com.google.chrome Android application?
This whole experience has re-affirmed my skepticism of passkeys in practice. I think it would be awesome to have public/private key security on my online accounts. I think it would be great if I could log in without having to copy/paste passwords (when autofill doesn't work, or for TOTP codes). But I have zero confidence that this opaque stream of bytes will actually work to get me logged in to my account. When the 1Password input field detection fails, I sigh, copy/paste my username and password, and then forget about the mild inconvenience after about 30 seconds. I don't even want to think about what would happen to an account if the only way to log in to an account was via passkeys.
Compared to: - PlayStation 5 - PlayStation 5 Pro
or: - Nintendo Switch - Nintendo Switch OLED - Nintendo Switch Lite
Anyone who's literate in English (and knows that OLED means "nicer screen") can immediately rank the PlayStations and Switches into "good, better, best". But with the Xbox, how is anyone supposed to know which one is which? Is the Series version better or worse? Is it a whole new generation, with whatever backwards-compatability implications that a new generation brings? I need a chart and I probably still won't be able to tell you if you ask me in a month.
Some quick math tells me that you can lift approximately a kilogram of mass per cubic meter (at sea level, anyway). If your balloon's full weight is a half of a kilogram, you'd only need about a large beach ball filled with hydrogen to lift it. That seems like something that would be attainable for an outdoor DIY electrolysis setup.
There's a tool called cdparanoia[1] whose goal is to babysit the CD drive and ensure that it gets a complete, perfect, uninterrupted stream of bits off the drive, and will use a lot of tricks to go back and re-read any data that didn't come back cleanly. I always used it with abcde[2], which was a wrapper around it with album lookup, tagging, and ffmpeg support. I highly recommend anyone amassing a CD rip collection take a look at it, both are still packaged in present-day Ubuntu.

Nextcloud provides all 3 in a package that pretty much just works, in my experience (despite being kinda slow).
The Notes app is a pretty nice wrapper around a specific folder full of markdown files, I mostly use it on my phone, and on my desktop I just use my favorite editor to poke at the .md files directly.
Oh, and when a friend group wanted a better way to figure out which day to get together, I just installed the Polls app with a few clicks and we use that now.
I am a bit disappointed in the performance, but I've been running this setup for years and it "just works" for me. I understand how it works, I know how to back it up (and, more importantly restore from that backup!)
If there's another open-source, self-hosted project that has WebDAV, CalDAV, and CardDAV all in one package, then I might consider switching, but for now Nextcloud is "good enough" for me.
Let's say, hypothetically, that Valve releases SteamOS to the general public, and it's received generally well, and it becomes much more common for people to use "that Linux thing" than it is today. Then let's say, hypothetically, that Valve turns evil and... I dunno, starts charging money for updates? At that point you've got a large population already using Linux, I'm sure there would be a pretty big migration to Ubuntu or some other mainstream Linux desktop.
I wonder how much of that is "hackers and experimentalists", versus random gamers* preferring Arch Linux's bleeding-edge latest-and-greatest packaging approach versus Ubuntu's seemingly-slower-paced development?
* though I suspect even the most casual 25% of PC gamers are probably significantly more tech-savvy than the average PC user of the population in general.
