I've been quiet on the blog lately. I was prepping for the Evolution meetings; since coming back, I've been mostly focusing on a revision of a paper. Paul McMillan's Google Summer of Code project is running along well (dbgraphnav) -- a beta might be on TreeTapper as early as next week. Already, it can be used to navigate from author to paper to author again -- since the database has many authors and papers already (~2000), it's pretty useful.
I just made something to parse a series of subversion logs to look at commits over time (so I can see how I'm allocating effort between projects). Here's a plot of TreeTapper commits. Some of the commits are automated backups of the DB, so it gives an overestimate of my productivity. However, it only tracks changes to the code, not additions to the database itself.
