P.S. I would be an asset in Unix-based projects, since I know my way around Unix pretty well, especially the core commands, concepts, tools and some system call usage (from C) (although not every nook and cranny or every last API). This comes from having had a lot of experience in it, as both a dev (doing business applications, mainly, but also a good amount of (CLI) utility development, often interfacing with the OS) and some informal Unix sysadmin-type work (including troubleshooting many kinds of problems involving interactions between applications and the Unix they run on), for a fair amount of time, for some years, earlier. This combined exposure to both dev and admin work on Unix-based platforms has given me good systems and applications strengths for doing Unix-based dev projects that require some understanding of and interaction with the OS. SVR3 and 4 and HP-UX were the main Unix variants I've worked on, apart from Linux.
