He's a mathematician, so what he means by "in general", is "in every possible case", or "without exception", so what I think he means is, "not all bugs will be found by code review." I agree it probably could have been made more clear.
Curl Noise[1] is also cool. I've used it to create some gas giant planets for video games [2] though I used opensimplex noise [3] rather than perlin as the base noise, but either will work.
My own efforts in this area amount to creating the game, Space Nerds in Space[1], which is a LAN game in which everyone gathers in a room with their computers, and each computer acts as one of the stations on the bridge of a starship: navigation, weapons, science, comms, engineering, damage control, etc. Multi-bridge is supported as well, so if you can overcome the insurmountable task of gathering enough people together, you can indulge in that luxury. This is in the same genre as such games as Artemis: spaceship bridge simulator and Empty Epsilon, but with the additional hurdle that it's linux only. Good luck mustering enough spacenerds. If there are missing features, well, it's open source, so it's got that going for it, which is nice.
Ukraine, in operation spiderweb, has already launched drones from containers deep within Russia to damage "... one third of Russia's strategic cruise missile carriers, estimated to be worth $US7 billion ..."
Similarly, Ben Travers didn't have a delay pedal, so learned to pick the delayed parts on Pink Floyd's "Run like hell" when he was younger, since taken to ludicrous speed: https://www.youtube.com/watch?v=1CY0_HG8J5M
The TI99/4a version of the Logo language which has turtle graphics used user defined characters to implement them. There were only (I think) 128 user definable characters, and when the turtle graphics had redefined all of them to create its output, it gave the user a message, "out of ink".
Interesting... RP2040 seems like maybe a bit overkill for a zero power badge. I've participated in writing some software for an RP2040 powered badge for the RVASEC conference in Richmond, VA, for several years, and the RP2040 is really nice to program for, and is quite powerful. https://www.youtube.com/watch?v=A5ZrHAXCFLA
PRs can contain multiple commits. You need something like stgit to make it easy to make a bunch of small commits that appear to be the work of an omniscient genius who knew exactly what they were doing. Try using stgit for awhile, and you'll wonder how you ever lived without it.
Something like those switches might be made very cheaply with a 3D printer, possibly a laser cutter, some transparent or semitransparent acrylic sheet, tactile switches and some LEDs. I designed a cheapo replacement for $50 tellite switches and got the price down to about $0.60 Not quite the same, as these are a lot bigger, and getting things down to the desired size might be troublesome. Anyway, here's a little video of my fake cheapo tellite switches: https://www.youtube.com/watch?v=LaenrgPVCjc
I found it funny that in a sentence that mentions "those who can recognize an LLM’s reveals", a few words later, there's an em-dash. I've often used em-dashes myself, so I find it a bit annoying that use of em-dashes is widely considered to be an AI tell.
