Databases and container networking.
Elif Demir covers data layers and how containers reach each other: SQLite locking under concurrency, D1 statement and variable limits, Docker and WSL2 network modes, and the connection errors those two worlds produce.
Method: database behaviour is reproduced against a real file or a real D1 database, with the lock state or the failing statement quoted from the session that produced it. Articles state which version was used, because SQLite and D1 behaviour differs between releases.
