The world’s most popular open source database, MySQL… which also happens to support this blog… is in the middle of an interesting struggle right now. UNH has a ton of dependency on both Oracle and MySQL, so we should be interested.
For me, MySQL was the free database I could learn on my own time. That means a lot when you’re broke. My own bias towards developing with non-commercial software stems from nothing more than preferring the hammer that is always within reach, regardless of financial standing. I think there’s something worth preserving in that.
