It's amazing how difficult the first entry can be ;) I have to do this from the office because I had a really bad HD experience with my workstation at home and I didn't have anything useable until it was well past the time my mind wanted sleep. I run FreeBSD 4.0 now and I will admit I find a lot to recommend it over 3.4. Over the month and a bit that we tested the release candidates (we always need more bodies in FreeBSD-QA ---hint ;)) I personally found it to be a little quicker and (arguably) more stable by the time it was released. I still use 3.4 for my gateway/firewall, but that's because there are some issues with 4.0 and older IDE drives/BIOSes.
In my day job I'm a senior support specialist for a set of network management tools and the associated environments (Oracle, Sybase, Solaris, HP-UX, NT) but in all honesty I tend to be much happier when I'm hacking out code. I did take a bit of a break from coding, because after 9 years of C my mind was getting a little squishy around the edges.
Anyhow, I'm back to do some Open Source work, but I haven't found a project yet that really grabs my imagination. When I find one (or if one finds me) I'll be sure to mention it. In the mean-time, I'll probably start looking into fixing some of the FreeBSD bugs as a way to familiarize myself with the code base.
