I research ways to write software that make it easier for newcomers to understand rather than for insiders to maintain (http://akkartik.name/about).

Lately I work on designing more testable interfaces for OS syscalls (https://github.com/akkartik/mu/blob/master/subx/Readme.md), growing the kinds of tests that can be written and improving the guardrails software can provide outsiders who want to understand its internals.
