Most codebases grow in directions their authors never anticipated. The pressure to optimize early is real, but constraints often produce more elegant solutions than freedom ever could.

Lessons from legacy codebases
Distributed systems fail in ways that are hard to predict. After years of debugging production incidents, certain patterns keep recurring. This post explores a few.

Performance optimization is a tempting distraction. Every line of code that exists to optimize one specific case is a line that must be maintained and understood forever.
