Edit: The source code for this post is located on GitHub Sometimes when I travel I end up trying to learn something completely new. For a while I was playing with Rust, Capn Proto, Scala, or I’d start a throwaway project at an airport and just tinker. My passion is and has always been databases. I’ve maintained this blog for roughly a decade, starting with MySQL for the first part of my career but moving to Apache Cassandra several years ago, and am now a committer and member of the PMC.
