Ok, so DBD::SQLite is entirely too cool.
I spent most of today mining data from log files and stashing it in an SQLite database, which lets me easily pull out particular parts of it for display in cute little gnuplot graphs. It's pretty neat, and way easier than setting up a real database. I love using perl for this kind of thing, it really shines at it.
Of course, I didn't get quite far enough to actually extract any useful data from my logs, but that's just a matter of turning my scripts lose on a larger data set.
At least I hope it is...
