Learn Rust the Dangerous Way
LRtDW is a series of articles putting Rust features in context for low-level C programmers who maybe don’t have a formal CS background — the sort of people who work on firmware, game engines, OS kernels, and the like. Basically, people like me.

Modern SAT solvers: fast, neat and underused
In part 1 of this series, we built a Sudoku solver based on translating Sudoku to SAT and then giving the resulting SAT instance to a SAT solver. We also benchmarked our solver and found out that it, unsurprisingly, loses to the state of the art of Sudoku solvers. Since

Once upon a time, my computer architecture professor mentioned that using a random eviction policy for caches really isn't so bad. That random eviction isn't bad can be surprising — if your cache fills up and you have to get rid of something, choosing the least recently used (LRU) is an obvious choice, since you're…
