Hacking
Well, of a sort. My first piece of production code went into use today. Let's see how long it takes for them to break it. It's not the first code that I've written that's in something important, but it is the first code that I and I alone am responsible for. Which, to me, is a big deal, because anything that's wrong with it I pay for.
Not that a set of three CGI scripts that set and remove vacation messages and forwarding is really a big deal, but I worked really hard on them, and I'd like to think that I did a good job.
