It was recently pointed out on lobste.rs that Zig has overhauled how its parser does operator precedence. The related documentation contains this cute little flowchart of the new operator precedence rules:

I've seen lots of chatter about Fil-C recently, which pitches itself as a memory safe implementation of C/C++. You can read the gritty details of how this is achieved, but for people coming across it for the first time, I think there is value in showing a simplified version, as once you've understood the simplified…
I'm the kind of person who thinks about the design and implementation of hash tables. One design which I find particularly cute, and I think deserves a bit more publicity, is Robin Hood open-addressing with linear probing and power-of-two table size. If you're not familiar with hash table terminology, that might look…
Much has been written about how to generate random 64-bit integers; people might argue over which particular (CS)PRNG is best suited for a given task, but there is agreement on the general shape of the solution: keep some state around, and then extract 64 bits of randomness at a time, where each bit is equally likely…
Computing the CRC-32C of a 4KB buffer on a modern x86 chip can be done as a simple loop around the crc32 instruction:
Given the current register state for a thread, and read-only access to memory, what would the register state hypothetically become if the current function was to immediately return and execution was to resume in its caller?
