Called Mad

I write about the things that didn't work the first time — the GIL refusing to speed anything up, a validator quietly returning None, a query that couldn't see its own column. Every post here started as something I got wrong.

Notes are kept in public partly because writing an explanation is the fastest way to find out whether I actually understood something, and partly because the version of me from two months ago would have found them useful.

FAQ

PostgreSQL, through SQLAlchemy's async engine and Alembic migrations — the schema is in the repository, not a claim.

It's public on OstapchukIryna/fastapi-blog to read, but there's no license attached yet, so it isn't open for reuse by default. Ask first.

No RSS feed and no comment system. The read-only JSON API (/api/posts) is the closest thing to a feed; if something's wrong or worth discussing, write to me directly — see below.

On purpose — a Monokai-style palette, one accent color, the ground a syntax theme uses, laid out for reading long prose instead of scanning code.
