Text To Diagrams Tools 🍼

I am a big fan of diagrams as code. I personally thought there was like 3 or 4 tools, but it appears there is a whole collection of tools for different purposes like sequence diagrams, database modelling, classes diagrams and many more. Find a huge list inside.

Reddit Consolidated Metadata Storage 👷‍♂️

Post on Reddit... about Reddit! They consolidated their metadata storage into a new architecture using AWS Aurora Postgres instead of Apache Cassandra, which is kinda surpising to me.
