About

GNU/Linux programmer/performance engineer and command line junkie. He/him.

Primary maintainer of the Stack Overflow tag wiki.

I like efficient code, and knowing how things really work.

I mostly use C/C++ (and perl/bash) on Linux, but I mostly look at assembly-language stuff on SO because it's more interesting to me, and there are fewer people posting good asm answers.

(profile pic is from https://xkcd.com/386/, and describes me perfectly. Incomplete answers/explanations make me crazy.)
