Two friends preparing their Fantacalcio auction together during a summer holiday

I Built a Model for Fantacalcio. The Useful Part Is When It Says No.

I started with Milan in Championship Manager 03/04, went through an almost perfect auction and a season shaped by injuries, then built Fantabuddy on holiday: a system that turns player lists, history and APIs into an auditable auction report.

dbt Core v2: 77 Rust crates, 18 Python files, no Python runtime

dbt rewrote itself in Rust. The speed is the boring part.

I opened a bug report against dbt and found a codebase nobody had told me about: 77 Rust crates where the Python used to be. This is what the rewrite is actually for, why the marketing undersells it, and what I broke loose while poking at it — two fixes, both for bugs that never printed an error.
