ballin#One night — after a glass of wine — I had another idea: one modern trick with ASCII art is the use of Braille unicode characters to allow for very high detail. That reminded me of ball physics simulations, so what about building a full physics simulator also in the terminal? So I asked Opus 4.5 to create a terminal physics simulator with the rapier 2D physics engine and a detailed explanation of the Braille character trick: this time Opus did better and completed it in one-shot, so I spent more time making it colorful and fun. I pessimistically thought the engine would only be able to handle a few hundred balls: instead, the Rust codebase can handle over 10,000 logical balls!
The FTC is calling this policy change a move in the right direction, but psychologists and privacy experts alike warn it’s allowing companies to overreach in data collection, underscoring any pseudo-privacy measures, and the damage to children has already been done.

As I said, this time the design notes were extensive since I wanted this emulator to be specifically designed for embedded systems, so only 48k emulation, optional framebuffer rendering, very little additional memory used (no big lookup tables for ULA/Z80 access contention), ROM not copied in the RAM to avoid using additional 16k of memory, but just referenced during the initialization (so we have just a copy in the executable), and so forth.
