Today’s read: why Uber moved from Postgres to MySQL.
Really interesting deep dive into the database internals and scaling problems that led to the decision.
For Uber, things like MVCC, replication, WAL, and write amplification became serious scaling challenges.
The interesting part is how they solved it.
One of those reads that makes you look at databases differently.

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?

y'all realize an MCP server is just an API that describes itself right?

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.

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

I highly recommend to read at least one technical blog per day or even per week ... the amount of depth you can get in your conversations with interviewer/friends/seniors solely from this highly appreciable
