I am a systems engineer/applied mathemetician (depending who you ask) at a government contractor in Northern Virginia. I primarily work in the development of new sensors and systems, focusing on the algorithms and overall system concept rather than the software, so I consider myself a beginner when it comes to programming and networking. Right now I primarily work in Matlab, but I have also worked in Java and C++ in the past.
My SO pet peeve - commenting on an answer to say, "Thanks, that solved it!" but not marking the answer as correct!
