    The other interesting trick is you need a separate RNG for visual only affects such as particles than the one you use for the physics simulation. Depending on the game during repla…

    One of the hardest determinism bugs I had to solve on the PlayStation three was that the PPU and the SPU actually used a different instruction set and had a different internal floa…

    Instant replays that require long-term deterministic behavior have to be bit perfect in a way that is dramatically hard harder to implement if trying to also do network synchroniza…

    E13 was a great, simple, good looking WM I used for years. Eventually moved to Fluxbox then back to macOS when it went Unixy.

    You are comparing orbiting earth in a shuttle to a lunar flyby in a pod. Very different risk profiles.

    Messaging platforms where people receive and promptly respond to messages are more successful in the long run. That's why SMS overtook email. If you own a messaging platform there …

    As best I can tell we've never sold the same product twice. Product roadmap is "whatever the last person I spoke to asked for." And tech debt maintaining a grab bag of 5,000 almost…

    Is this just a case of waiting to stay private while still giving current employees some liquidity?

    Yeah I thought LIDAR was used for actual focus and depth map was then computed from the multi-camera parallax.

    CORE only works on kernels that support BTF. This post introduces one workaround which is to generate BTF data for kernels without it. That's still only half the problem though. Yo…

    As someone who studied physics and electronics for many years, I still appreciate an article like this for reminding me how profoundly weird science is. Working day to day with the…

    GitHub pissed me off recently by giving us a one month reminder of our renewal, but having required two months notice to reduce our number of seats. As a result, we are ending up p…

    If you exceed the inheritance tax exemption then you are taxed on the $10k so LTCG would be double taxing. You could argue that the inheritance tax should have a much lower exempti…

    Listen. If it’s never supposed to happen then you definitely want a customer to tell you if it happens. Best way to make sure that happens is to insult their mum. It’s just good en…

    The physics game sim step had to be hardcoded but you could vary the graphics rendering independently. That did mean you needed to use a different RNG for sim objects and graphics-…
