Others have commented on homebrew, but there are a couple "game engines" available for the Switch that don't require modding. Nintendo released their own, Game Maker Garage, which uses a block-based coding environment. There are also two I know of that use a more traditional programming language: SmileBASIC and Fuze.
Both are similar to PICO-8 or other "fantasy consoles" where you get a full environment that runs on-device, with a code editor, tools for editing sprites, tile maps, music, and sounds, and a library of stock assets. Fuze also has a cheap "player" app so your kid's friends wouldn't need to buy the full app to play anything she makes. I've only poked around them a bit, but they seem like pretty capable environments that might be a good option for a kid that's interested in programming. The obvious limitation is that you're locked in to that platform - as far as I can tell there's no way to run your games on PC.
Just got a Ryzen T14 - only had it for a few days but it's working great. Arch works well out of the box, but Debian needs a kernel and some firmware packages from sid in order to get WiFi working.
I can recommend the Anker vertical mouse as a budget option. I use that at home and a large trackball (Kensington Expert Mouse) at work, with a block of foam under one side so it sits at an angle. I found a small trackball to be more painful than a normal mouse, but the large one is an improvement and I didn't have any trouble adjusting to it. But YMMV.
Can anyone recommend a good course/book/tutorial for learning Verilog/VHDL? I have a demo board from a course I took in college and would love to try doing some projects with it, but I've had a hard time finding any good learning material.
Stefan Pochmann is also the inventor of two different methods for blindfolded Rubik's Cube solving. Classic Pochmann is a quite elegant solution as it effectively deals with one piece at a time, where previous methods generally separated orientation and permutation into separate steps, and deal with more pieces at once. M2 is 'tasty' in a different way - there are many more edge cases to handle but it replaces the 14-move swap sequence in Classic Pochmann with a single move. Perhaps I'm stretching a bit but it seems like an example of the same kind of thinking.
Side note - blindfold Rubik's Cube is way easier than you think. If you're a programmer and can already solve one sighted, I'd imagine you could learn Classic Pochmann in a week.
That should be NUL (one L). Interestingly, when I tried it in Powershell, 'type NUL' reports that the file does not exist, but in CMD, 'type NUL' outputs nothing (it's the DOS equivalent of UNIX's /dev/null). So apparently some APIs will allow you to use those as filenames while others will choke on them.
