My wife and I are working on a math/science/CS-inspired jewelry business.
We try to create pieces that stand on their own aesthetically but have a hidden meaning. We currently have two styles: lambda calculus based pieces (we depict the lambda/Tromp diagram) where we have Y-Combinator earrings (well, strictly speaking they are one beta reduction away from Y-combinator. Aesthetic oblige) and a pendant depicting a lambda expression computing Graham's number. The other style is quantum computing circuits, based on quantum computing research my brother (a physics professor) is doing: a pendant that is actually a non-local controlled-NOT gate.
I wrote a tiny DSL to describe the jewelry pieces, and an interpreter to produce CAD files. We then either 3D print them or have them produced by lost-wax.
We are 200% out of our comfort zone (and love it): I know nothing of front end dev, payments, or anything like that. The diamond district in New York is a neighborhood we normally actively avoid, but if you are forced to go there it is fascinating (people examining diamonds on the corner of the street, others in fur coats in summer straight out of a mafia movie...), and especial marketing. Jewelry is a completely saturated business (luckily we are not doing this to pay the rent); we think we have a unique angle, but we are still figuring out the target audience (if there is one), how to advertise, etc.

What I often ended up doing is asking it to draw 3 labeled arrows X,Y,Z. So I could tell it to orient along the XY labeled arrows (which are in reality YZ, but whatever).
Built a tool to help design cs/science inspired jewelry in CAD. I wrote a DSL to describe the jewelry, and had an LLM write the interpreter to generate a CAD file using cadquery (note to self: LLM suck at 3d reasoning). I would not have had the time to do this without AI.
Also used AI to design an online store (I'm not a front end dev). It's amazing to see my wife (non-technical background) tweak the web-site using claude code.
End result: an online store where we sell jewelry pieces that actually are lambda-diagrams (Tromp diagrams) that compute Graham's number, or of the Y-combinator (well, technically it's just a fixed point operator, one beta reduction away from the Y-combinator. But Y-combinator was not aesthetically pleasing from a jewelry point of view)

If I remember correctly, in that book Galileo says he heard of someone in the Netherlands having made a microscope, but without any details about how it was made. Armed with the knowledge that something like that was possible, he designs a telescope (lenses only, not a Newton type telescope with a mirror). He build three and used the last and best to do his observations.
Galileo refers in this to a book he had published earlier, the "Starry Messenger". It is well worth reading.
Galileo had just build the first ever telescope and he describes what he has discovered: there are incredibly more stars than can be seen by the naked eye; Jupiter has satellites; there are mountains on the moon and he has figured out their height from the length of their shadows... The book is full of the quiet excitement of a man who has discovered a new world, and seen what no man had seen before.
If you like Bach you might want to learn to listen to polyphony: the form of music in which multiple melodies are played simultaneously while forming an harmonious whole. I recommend looking & listening to videos of Stephen Malinowsky (smalin on youtube), particularly his older videos with less visual clutter. Each color is a separate melody. Initially and you should try to focus on just one melody, then see if you can easily switch your focus to an other one. Then see if you can listen/focus on two melodies at the same time, then three... https://www.youtube.com/playlist?list=PL81D26D4A47388279
In general I would not worry to much about the performer, but it might be interesting to listen to different interpretations of the same piece, particularly from composers with very idiosyncratic styles. On youtube, Ashish Xiangyi Kumar (https://www.youtube.com/c/AshishXiangyiKumar) has videos of pieces (mainly piano solo) interpreted by different artist.
I was using sed to do many replacements (hundreds) in a file and it was starting to be slow, running in O(num_replacemnts). I thought that this can be done with a state machine so the runtime could be independent of the number of replacements.
I googled a bit and found this amazing gem: it uses lex to create a custom C program that does just what you want. Posix compliant. All wrapped up in bash function.
If you specify many replacement rules in sed, it will run in O(num_replacements * num_lines). You should be able to use a state machine to do it in O(num_lines), so I google a bit and found this amazing gem: https://unix.stackexchange.com/a/137932
tl;dr: it uses lex to create a custom C program that does "just what you need", compiles it, and runs it on your input. The whole thing wrapped in a bash function. Bonus: it's POSIX compliant.
If I remember correctly, the system calls where indirect jumps where the address of the jump was in ram (it had been copied from the rom on startup): it was designed to you could hijack system calls and modify their behavior. This blew my mind as a teenager.
I wish modern system where still designed like that...
I have heard that it is good practice to always chose the number of teeth of two gears to be relatively prime. This is because there can be impurities in the metal, and if you have a small part of a tooth that is harder than the rest it will erode the opposing gear (there is always some friction going on). By choosing the number of teeth to be relatively prime, the wear and tear is distributed uniformly on the gears, and thus they last longer.
In some/many cases there is code before the branch that does not influence the branch condition. In that case, would it be possible to architect the cpu such that it could execute the branch 'early'? I'm thinking of a special asm instruction like 'execute the next 4 instructions, and only then do the conditional jump'.
