A minimal kernel in Swift, running in QEMU
Update (28th of September 2026) Max Desiatov told me that the @c swift attribute should work, instead of declaring the functions using @_cdecl. The @c attribute marks a global function as a C function implemented in Swift, which formalizes the @_cdecl attribute. A link to the proposal is available here. I did update…

Types as axioms, or: playing god with static types
A common perspective is that types are restrictions . Static types restrict the set of values a variable may contain, capturing some subset of the space of “all possible values.” Under this worldview, a typechecker is sort of like an oracle, predicting which values will end up where when the program runs and making…

Implementing a Tor relay from scratch in golang (2015)
Update from the author, over a decade later: Go has improved and so have my own skills. The conclusion of this article was that Go isn't the right language for the task I gave it, and that's no longer true today, but also wasn't true when I wrote the article.
