Bytefisk is a coding blog for developers who care about how software actually works under the hood.
The long-form posts go deep on the things that matter when you ship real systems: scaling databases, debugging distributed failures, understanding OS internals, building with AI, and the architecture decisions that hold up — or don't — when traffic grows by an order of magnitude. Every post includes real code, real numbers, and real trade-offs.
