the Mansible of Ansible
Because of Geerling's early videos on Ansible - I started looking into Ansible and learning it. Also, went down the rabbit hole on how to compile a kernel. (For no real reason other than I could).

Pi4 2GB with power source, SD card, case, fan is like $100. You can have nice Atom MiniPC for that. Or old PC from ebay...
But these are used, cheap new Atom miniPC doesn't have GPIO, and brand new Atom SBCs with GPIO are more $$$ with the same SoC compared to miniPC since they aren't mass produced. A used Pi with sdcard/case/fan is much less than $40.

USB GPIO dongles are a cheap addon to any x86 PC, e.g. "Adafruit General Purpose USB to GPIO" at https://www.adafruit.com/product/2264
These tend to have buffer underrun issues causing latency in the order of seconds, requiring deeper knowledge in the embedded field to mitigate.
Most educational content that involve the Pi tend to use system GPIO libraries and integration, making other SBCs or USB expansion boards difficult to use for newcomers. The Pi is a platform other than the hardware, their forum should be more welcoming though.

#44Utterly wholesome is the perfect description. It's an instant click from me any time his videos (or hn posts) pop up. I get the same feeling from Jeff's videos I did when I watched PBS as a kid. That's not a dig; I find his videos extremely calming, informative, and well produced. The man radiates positivity and kindness. That's a rarity these days on YouTube. Presumably "high energy" content does better algorithmica…
A bit different, but this is why I like watching Decino [1] who makes WAD playthroughs and analysis videos of Doom.
No yelling or clickbait titles, just someone calmly playing Doom and while explaining game mechanics and level design.

#45I love all Geerling's projects, writings, and videos over the years. I was actually concerned that based on the brevity of the title that something tragic had happened. Glad that's not the case!
Probably the headline auto "correcter" lopped off the "Meet" part of the original title. Yet another example of that piece of software being too clever by half if you ask me.
This is the stupidest HN feature. It does very little for clickbait (flagging and voting is better), and routinely screws up titles to the point it drastically changes or reverses their meaning.

Yep it's a complete anti-feature and I have no idea why it's still in use.

Same, especially since he has shared a lot about his Crohn disease online https://www.jeffgeerling.com/blog/2022/crohns-disease-takes-...
I should hope I have time to post more before I'd have anything too radical happen :D
Typically with Crohn's issues you have weeks or months of fun issues that lead up to anything too serious! (But not always)

#49> It’s like the tool world: I use DEWALT mostly, because the first tool I bought was a DEWALT. So you gotta use the DEWALT battery, and then you’re like, well, I could buy this cheaper tool, it’s better. But then it won’t work with my battery. So now I have something like 25 DEWALT tools.
Oh man, this is something I wish the EU would work on fixing. There's no reason there couldn't be a battery standard.

The Pi 5's PCIe implementation has a lot of fixes—to the point where after only a few days of work, Coreforge over on GitHub has Minecraft rendering through the GPU (only at x1 speed so far).
The CM4 uses the silicon from Pi 4, which was never really a fully-baked PCIe implementation, so I'll forgive them a little there. But it opened up a huge number of possibilities that I think will be realized on Pi 5 (and hopefully a CM5 eventually).
And regarding power consumption / efficiency, don't forget about the usefulness of a full Linux computer running at less than a watt (like the Zero 2 W); or with the Pi 5 you can use the watchdog timer to boot and shut down now, going from idle at 2-3W to power off at 0.01W if you need a remote 'edge' device.
But the hardware and efficiency were never the primary drivers for Pi. It's the fact you can buy one (well, sometimes...) and use it. You don't have to spend a few hours getting the right OS, figuring out the right tools to flash it reading sparse forum-based documentation...
