A popular data-oriented design pattern is a Struct of Arrays. Is an Array of Enums also useful? Yes! But let’s do a refresher on struct of arrays (SoA) first: If you have a Thing, const Thing = struct { checksum: u128, number: u32, flag: u8, }; and an array of Things, // Array of Structs. const AoS = []Thing; it's p...

When the files change, you want your friends to be able to download just the changes without needing to re-download the entire directory again. And you want this to scale, no matter how many or how large the files are. What's the best way...

25 years after the introduction of the 32 bit Intel i386 CPU, all Intel compatibles still start up (and wake up!) in 16 bit stone-age mode, and they have to be switched into 32/64 bit mode to be usable. Wouldn’t it be nice if a modern i386/x86_64 CPU started at least in 32 bit protected mode? Can’t they make a legac...
