tl;dr:“I’ve been a developer, a manager, a cofounder, and now I'm a developer again. I ran away from each position until being a founder because I felt like I was limited by what I was allowed to do. But I reached an enlightment of sorts during my career progression: that everyone around me was dying for someone to pick things up, for employees to show engagement and agency. We think of our titles as our limits. We're quick to say and believe, "that isn't my job". While in reality titles reflect the minimum expected of us, not the maximum that is open to us.”
tl;dr:“Databases are fun. They sit at the confluence of Computer Science topics that might otherwise not seem practical in life as a developer. For example, every database with a query language is also a programming language implementation of some caliber. That doesn't include all databases though of course; see: RocksDB, FoundationDB, TigerBeetle, etc. This post looks at how various databases execute expressions in their query language.”
