The first release of Snapper for the BBC Micro featured the familiar arcade game Pac-Man character and ghosts - as shown in the magazine advert. However, potential legal issues resulted in modifications to the graphics and later releases had Pac-Man wearing a hat and four 'alien' like creatures.

Top-Down Development is good when you know your end goal. If you know your end goal you are probably doing something that was done before. If you're doing something that was done before just ask an LLM to generate it. Real Innovators go Bottom-Up.

#AdventOfCode adventofcode.com/2024/day/3 Decided to learn how to use Parsec instead of a hand rolled state machine. Was nice to use but took me a while to figure out how to parse only the good stuff and drop the garbage between tokens, as required by the problem. github.com/justinhj/adv...
