Charles Leifer's charlesleifer.com is a long-running engineering blog focused on Python and database internals. He's the author of the peewee ORM and several SQLite-adjacent Python libraries; his most-cited single post is Building a simple Redis server in Python (~10 years old, still the canonical "from-zero Redis protocol" tutorial). The site has the rare property of holding up after a decade — the prediction posts (Disque-will-be-abandonware, why-database-design-X-was-the-right-call) are worth keeping because the followup posts later confirm them.
The writing style is direct, opinionated, and grounded in code-level familiarity with the subjects — Leifer doesn't quote others' analyses, he reads the patches.
