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”!

Incel shit.

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.

You’re spot on.

With about 10% overhead on the travel time, a pretty mainline high speed rail line would take about 15 hours to go from DC to San Fransisco. Each train (assuming Japanese trains like Amtrak is buying for Texas) can carry about 1323 seats, plus standing room. They can run 16 trains per line per hour. So, that’s 21,168 people per hour passing on the rail.

Assuming the 15 hour lead time (and no loading time of note because Sergents are really good at yelling people onto trains), within 24 hours, the Pentagon could move about 211,680 soldiers coast to cost from time t=0 to t=24 hours. That’s coast to coast, mind. If you do it from say the middle of the country to SF, it’s only a 4.7 hour trip, so now you can get 19.3 hours of soldiers moving (and arrived) around 408,542 people delivered by t=24hrs. Then, it’s another 508,032 every 24 hours after that.

Now, while it’s not particularly feasible to have commercially driving HSR across the empty center of the US, the military has a whole different set of priorities, and damn, that’s a lot of equipment & people that could be moved really fast. Yes, planes are faster, but there’s no way they’ll keep up with HSR once the train pipeline fills. This is a latency vs carrying throughput load equation and trains will win it big time. Always have, always will.

The US way way way behind on building infrastructure. Our infrastructure deficit is trillions of dollars, and our transit modality is decades behind Europe, China, India, japan, and even starting to slip behind sections of Africa. We’re failing as a developed nation because we refuse to invest in modern transit (and many other issues like healthcare, usurious education costs, and losing our democracy to dictator thinking). We’re flailing hard right now. HSR should be a massive investment for our country, along with regional/city rail (trams, metros, heavy regional), but since our population mostly has never ever seen a modern city like Paris, London, Beijing, Tokyo, or Rome so they have no idea what it can even be like to live somewhere well designed for people instead for for cars.

Though, watching the military test the rails by moving a half million people in 24 hours would be hilarious for those of us not trying to coordinate it.

I use Google Docs for anything simple (1-3 pages), and if it has no citations or more than 2 figures. After that I upgrade to LaTeX.

I had a conference demand a docx file for the paper submission. I figured “fine it can’t be that bad to use word for a simple 8 page publication” but boy was I wrong! It was torture trying to get it formatted and arranged properly. Every part of the word tool is weird and clumsy.

Oh, and they’ve completely broken the original GUI WYSIWYG (what you see is what you get) premise of a GUI style editor. The PDF it creates often doesn’t look anything like what the document looks like on the screen.

I dropped a note on the conference organizers about the docx requirement. I don’t have that many hours to fuck around with bad tools so I can attend your venue. I’ll just go to a conference that doesn’t torture us to participate.

If the PoE is stable, then it’s a nice and relatively unique board. Not sure about the NPU support. There’s a ton of boards and chips coming out with those claims, but I’d like to be able to get clearer info on drivers and library compatibility.

I haven’t had time to seriously game in a decade now (single dad killed my free time), so I’m by no means well versed beyond a few things. My kids do game a lot and most of them are on Linux machines. They use a combination of Steam and standalone installs to get things working.

I don’t run into a lot of complaints. They’re well aware that not all games run on their Linux setups, so they pick and choose games a bit more. I’m fortunate that they’re not always jonesing for the latest AAA games, but they’re also getting new ones with some regularity.

It also does it so that you no longer hit the bootloader. My one last dual boot machine is normally a Linux setup, but every so often I have to use the real MS Office tools (some collaborator or publisher demands it), so I boot windows. Then windows patches and stops actually hitting grub so it acts like a windows only machine until I fix whatever Microsoft fucks up yet again.

It’s time to move to a VM for this garbage. I just don’t neet it more than once every other year so I never seem to get around to nuking it.

You can do set it up to detect a windows exe format and launch it in wine without any extra intervention.

Make sure to chown it to root first with that suid bit to make sure it can get the library and hardware access that needs every time.

My Linux machine goes… no permission to execute. I go “dang, not what I was looking for.”

I often usually post the chapters we use for my classes in case students haven’t bought the book yet. I also have a hard $60 limit for books that I use.
