where i find things worth reading
Good problems do not arrive on a schedule. These are what I read, and where what I read ends up.
- company tech blogsevery engineering blog worth following, in one feed — the problem always arrives before the write-up.
- system design roadmap77 topics as a dependency graph, each with the paper or postmortem that states it best.
- second brainthe vault — papers, posts and notes I keep coming back to.
- reading trackerthe open log — what I read, when, and the takeaway that survived the article.
- x (twitter)engineers arguing about a failure in public, months before anyone writes the postmortem.
- substacklong-form from people who actually operate the systems, not summaries of them.
