Ask HN: What weird technical scene are you fond/part of?

I hate it when a program I wrote mocks me. In Lex Fridman's interview of Steven Wolfram, he demonstrates the machine learning functions in Mathematica by taking a photo of himself, which identifies him as a .... (I won't give it away):

Here's a video I recently recorded of the CAM-6 simulator I implemented decades ago, and rewrote in JavaScript a few years ago.

I recorded that demo to show to Norman Margolus, who co-wrote the book and wrote the CAM6 PC Forth code and many rules, so it's pretty long and technical and starts out showing lots of code, but I'm sure you'll totally get and appreciate it. I linked to a pdf copy of the book in the comments, as well as the source code and playable app.

Show HN: Making a Falling Sand Simulator
Typically a cellular automata simulation will have some edge condition like wrapping or mirroring an adjacent cell.
A nice optimization trick is to make the cell buffers 2 cells wider and taller (or two times whatever the neighborhood radius is), and then before each generation you update the "gutter" by copying just the wrapped (or mirrored) pixels. Then your run the rule on the inset rectangle, and the code (in the inner loop) doesn't have to do bounds checking, and can assume there's a valid cell to read in all directions. That saves a hell of a lot of tests and branches in the inner loop.
Also, the Margolus neighborhood can be defined in terms of the Moore neighborhood + vertical phase (even/odd row) + horizontal phase (even/odd column) + time phase (even/odd time). Then you can tell if you're at an even or odd step, and which of the four squares of the grid you're in, to know what to do.
That's how the CAM6 worked in hardware: it used the x/y/time phases as additional bits of the index table lookup.

Here's how my CAM6 emulator computes the Margolus lookup table index, based on the 9 Moore neighbors + phaseTime, phaseX, and phaseY:

It's always been you, Canvas2D
Oh, nicely done! Trying to code up cellular automata simulations are pretty much guaranteed to push my brains through my nostrils - I've never progressed far beyond classic Conway. Your CAM6 library[1] may be about to steal my weekend from me!
