I write here to think out loud — about systems, tools, things I’ve built, and occasionally something with nothing to do with any of that.
How vectorized lookup and a couple of bit-packing tricks turn a memory-bound loop into a memcpy-fast monster.
How recursive thinking shapes clean, elegant solutions — and when to reach for it.
