Whew, a lot has happened since I last posted. I got married, honeymooned in Hawaii, took a trip to San Diego for a research project, then went to Las Vegas for defcon. I figured I should do a quick write-up. Defcon was at the Rio this year, and they brought back defcon tv, so we were actually able to watch several talks in the comfort of our hotel room. It worked out really well for those 10 am talks that are hard to get up for. I stayed at the Rio this year (didn't stay at the Riviera last year

I've made my first open source release! It's a project I developed for work that we've called SAI (SDG Agent Infrastructure), and we're releasing it because we weren't able to find something like it on the internet and had to write this ourselves. It's basically an agent that can download jobs and input from a server, execute those jobs, and then send the results back to the server. The jobs are just simple Python scripts, so there's really a lot you could do with it. With all the worry about
