Sean Goedecke

Sean Goedecke’s site is a personal engineering blog where he works through questions about how software is actually built and why it so often disappoints. Posts are essay-length arguments grounded in day-to-day development experience rather than product announcements or link roundups.

The central piece here examines performance: rewriting a program in C or Rust rarely delivers the speedups people expect, because most real systems spend their time waiting on databases, networks, and disk. Goedecke points out that where raw language speed does matter, popular libraries already close much of the gap, so design decisions dominate outcomes.

The blog suits working developers, tech leads, and anyone assessing claims that AI or a faster language will rescue a sluggish codebase. It rewards readers who want reasoning they can apply to their own architecture discussions rather than quick fixes.

A practical approach is to read the performance essay alongside your own system’s bottlenecks, then browse the archive for related posts on design and engineering tradeoffs. Treat the arguments as a starting point for evaluating your own assumptions about speed.
