Being a professional developer really takes some of the wind out of your non-professional sails. Last year, I had exactly two new repositories added to Github: git-wc and mp-suggest. The first was a simple wordcount handler for git that would calculate the difference between your current repository and your work in progress, and tell you how much you'd written that day. I wrote is as a tool for NaNoWriMo. The second is a fairly straightforward tool for taking apart a directory full of MP3 files and, depending upon the command line flags provided, prints out a bash script for making the contents of the directory consistent: same genre, same album, (possibly) same artist, and some heavy lifting to clean-up the titles, or to derive the titles from the filenames. It's not rocket science, but it was fun, it's a tool I use regularly, and it's written in Hy, a lisp written for the Python VM.
What did I do in 2014? Well, mostly I worked for my employer, Splunk, on a pair of projects: first a window manager for data panels associated with the Splunk server; and more recently with the latest revision of the Splunk for Microsoft Exchange application. I mastered the fine art of managing Splunk configuration files via its REST API, which is absolutely no fun (and the ACL API is a nightmare).
I'm still not sure what a Monad is.
