Your perspective might be why I enjoy microcontroller work. I love getting to know everything about the system, reading hardware documentation, and getting the low level parts to work in a highly deterministic way.

I use ATTiny85 cores when a ESP32 costs almost the same, but the 85 only has 256 bytes of SRAM and five I/O pins so I can track it all and ensure it will do exactly what I want.

The same meme with “wiring and lights” at the top. Then you descend to motors, transformers delta-y phases, RC and RL circuits, op amps, BJT circuits, reverse bias what?, differential equations, and eventually signals and systems.

The summary that I liked from the last post was “python is the second best language for everything”. There’s always something specialized and better for every given job. But, if you want one tool that’ll do a solid job everywhere, python is your go to.

We’re entering the ‘blockchain for every need’ stage. Expect massive money to flow into scams, poor ideas, and outright dangerous uses for a few years .

Before Blockchain we had ‘the web’ itself in the dot com era. Before that? I saw it in basic computing as a solution to everything.

I had a student came into office hours asking why their program got a bad grade. I looked and it didn’t actually do anything related to the assignment.

Upon further query, they objected saying that the CI pipeline built it just fine.

So …yeah… You can write a program that builds and runs, but doesn’t do the required tasks, which makes it wrong. This was not a concept they’d figured out yet.

As per all too often, the functional programming world invented them. Haskell (and its ilk) usually has all the future cool stuff already. Then python picks it up, then it moves over to C#/Java, then C++ says “mee too”!

They did that to my daughter. I’d setup a laptop for her. The windows boot partition was still there (my bad for scraping every last bit of Windows off - it was setup in haste) and she accidentally chose windows from grub one day. The Windows Bootloader decided to change boot options in the bios and then remove grub somehow, but there was no windows on disk to launch so it was bricked.

The next time I could out hands on the computer I scoured that disk clean of Microsoft’s plague rats so they wouldn’t get a finger in edgewise again.

woke Marxist liberal critical race theory.

Any more smooth brain buzzwords we can throw in there?

Incel shit.

Every Olympics is a political catastrophe. I’ve now watched all too many of them. They’re huge events and all it takes is some controversy or a fuck up by some middle manager and the whole world freaks out.

Overall, this one East that bad on France’s, except probably the river pollution thing (which I hope pushes them to long term cleanup efforts). Most of the rest was all the USA (we’re #1 in being assholes to people) being assholes. Our pearl clutching about religious insensitivity, transphobic right wing hatred, and generally bring dicks was well over the top. So, that’s not on France, but the US and our own swimming in Christian nationalist right wing sewage that spilled over onto the rest of the Olympics.

Video games. I used to play 4-6 hours per day (or often more), every day. It was kind of my default activity when I wasn’t forced to do something else. If I ran out of steam trying to focus on work or family I would drift into playing a video game. The result was a MASSIVE sink of time into something that left me with little afterwards. I didn’t learn new things, I drifted away from my kids, and I didn’t take care of my home.

Video games are fine. They’re entertaining, but they’re also potentially life consuming. I watch people who want to do more with their lives, but instead they just put more time into some game or another.

I managed to kick the habit and it’s been a great 10 years since then where I play very little and only in very short, controlled bursts when I can play with my kids for a bit (they usually destroy me these days). With all of that saved time, my career started flying, my home is in better shape, and I actually don’t drift away from family events like I used to.

Yeah, those durn data size fields. At first you’re like “why would you do this? It’s specified in the spec, right?” Then you start consuming the data stream and go “oh, yeah need this”.

I was doing some driver work for a real time location tracking board. The serial stream protocol was very well documented and designed. Plenty of byte length count fields, though.

This approach is so much nicer than the threading/queuing approaches we used to have. One async showed up, a ton of the work go pulled out of protocol handing and distributed subsystem sync efforts.

Long lived the multi threaded C++ server buffer! Today, async beging to rule the roost.

Aw darn it. Now I’m reading your posts with an Australian accent in my head.

I’ve been accused of being a bot in online games due to my robust vocabulary, resistance to abbreviation and slang, as well as pedantic punctuation use. It has been happening for decades.

Note: rarely have I been accused of a being a bot for my skill at gameplay. We all have our strengths and weaknesses.

Now, if you wish to truly delve the depths of linguistic proclivities, one should peruse the works of Terry Pratchett, especially the Discworld novels. Any and all of his works are wonderful prose and deep storytelling.

At one point my 1GB disk was the “big one” in the dorm. It was the windows share of some random media. I had room for the whole 40MB videos “Jesus vs Frosty” (The Spirit of Christmas) and “Jesus vs Santa Claus”. It was before South Park became an actual show, but people watched those 100’s of times off my hard drive.

When I bought a 3GB from Fry’s it was an open question how we’d fill it. Of course, that was just as the mp3 codec started to gain traction… Problem solved.

I have it on the shelf, but haven’t gotten to it. I’ll put it in the reading queue.

There was also a competition (long ago) to see who could build a computer that would successfully boot Windows 95. The goal was to boot the slowest possible time (no arbitrary delays allowed).

The winner wrote a shim that emulated a floating point unit of the i486 so it would boot on a i386 (no floating point). The result was… booting after many weeks. They won big time.

I did some similar stuff on a Raspberry Pi. I had to NFS mount my desktop and make a swapdisk on the NFS mount to have enough RAM to build. It wasn’t fast, but it did eventually work.

We used a RPi 4 for a Plex server for a while. It was fine except it couldn’t do any live transcoding or handle h265 worth beans.

I upgraded to an OrangePi 5. I’m on a sata drive for the OS and a external USB disk for media. The thing is amazing!

No, it’s not a $50 computer. Yes, it works great.

I love RPi boards, but their hardware limitations are quick to be found as you move past simple hobbyist projects.
