So, TrainSignal FTW! That is all. About 3 weeks back now we had David Davis on the BrownBags, and while the Video has been up on Vimeo Iâ€™ve been lax in getting it posted. One of those things that if I donâ€™t take care of it right away I seem to forget. Not that David is forgettableâ€¦ far from it. In fact, if you listen closely, at the end of the BrownBag we get an awesome sound byte too!
