A Simple CPU on the Game of Life (2021)
- pron 1y agoThat's just beautiful!
- JKCalhoun 1y agoNow if there were some custom FPGA that ran the life rules…
- mwcz 1y agoFirst, I thought "not so simple!" But it's wonderfully grokkable compared to zooming in on equivalent hardware and watching transistor states unfold.
- kimixa 1y agoI think I see the opposite - a Game of Life logic gate is way harder to understand than just a symbol representing the logic itself. And I see most logic gate transistor implementations as much simpler and so easier.
- ninetyninenine 1y agoRight but the motion of each signal is observable in the game of life version.
- mwcz 1y agoI meant zooming in on the hardware very literally. Watching electrons in a transistor. Logic diagrams are naturally easier to understand than what they describe.
- waltbosz 1y agoIt's a funny coincidence, the game of life computer reminded me of the human computer they built in the book "Three Body Problem", and your comment uses the term "grok" from the book "Stranger in a Strange Land", two scifi books I read recently.
- mwcz 1y agoLet's write an algorithm that ranks HN by number of oblique sci-fi book references!

- dvrj101 1y agocould not find what the stack he used for the site, it looks so good and readable. Anyone have any clue ?
- TheOtherHobbes 1y agoConway would have loved this.
- nokeya 1y agoNow run DOOM on it
- fredley 1y agoFun challenge for AoC…
