Would you use a database from this guy?
fourspaces.com: FeatherDB - Java JSON Document database
Or at least I should have been. At the time, CouchDB was (and is) very much a work in progress... there were a bunch of things that were planned but were missing, such as: support for stored/named views and any sort of authentication. No problem! I'll just add this myself!
Problem: CouchDB is written in Erlang.
I don't do Erlang.
I don't have anything against Erlang... we've never met. I just don't want to learn another language. Especially one that is so specialized. I know that I should learn a language a year, but Erlang was just too much of a hurdle for me to get in and start mucking around in code. Plus, would you really accept a patch from a guy that is just learning a language? Neither would I.
No problem! I'll write my own Java version of CouchDB... and do it better. The result was/is FeatherDB."
(Emphasis Added by me)
So I ask you, dear reader of this blog, would you really accept a database from a guy that writes a Java clone of an entire database system just to avoid learning a language to add a couple of missing features? What a terrible reason to reinvent the wheel. Java developers can connect to CouchDB using CouchDB4J, the Java client for CouchDB.
I found Erlang ridiculously easy to learn. "Especially one that is so specialized"? Specialized in what, being incredibly reliable, scalable, cross-platform, and mature? Brutal.

Damien makes the point that Erlang's share-nothing processes make it possible for garbage collection to work in high activity situations. In shared state threading systems, garbage collectors can't keep up and the system becomes a timebomb. Erlang FTW!

Less than 52 hours until I'm done
I have a final exam at 2pm on Wednesday. It's my only final exam this term out of four courses. If you're thinking "lucky guy" you're wrong. Classes that don't have final exams make up for it by having a big final project instead.
Final project: A week or more of solid work
Final exam: Study for a few hours and write an exam
Sure, you get more out of a project than an exam, but when you have three of them all due at the same time, it's not easy to manage. Actually, the course that does have a final exam also had an assignment due on the last day of class, but it wasn't as big as the projects for the other classes.
Anyway, 52 hours from now I will be finished my undergraduate studies! How should I celebrate?
