It's insane how people sleep on SQLite in production. It's the absolute cheat-code. The fastest db money can buy. Infinitely scalable. All queries are 90% faster than a single roundtrip to Supabase. Literally unbeatable. Why wouldn't you start every single app with SQLite?

A lot of software doesn’t need a rewrite. It needs someone to delete 30% of it, remove two dependencies, rename the confusing bits and stop adding features for a month😂

One of the worst things that AI has done in software is convinced low-skill individuals that software engineering is solved and is instantly producible. They then in turn project their unrealistic expectations onto others.

At the end of the day, it's just software. Go outside, touch some grass, and log off.

The better the tests, the faster you can ship. Even more so when agents are writing the code. This course teaches you how to get to such tests testdriven.io/courses/python…

Test-driven development is dead! Or so it seems, judging by the content on social media. Can't remember the last post about it. Everyone went all-in on AI coding. Is it really dead? Read the full blog post: jangiacomelli.com/blog/is-te…
