The first link is to a video presentation by Paul Dix on Reddis. Reddis is awesome! Paul does mention that, but he also goes into explaining why people thought he would be wear Angel's wings to this presentation. I have always known Paul as a straight man, but he is really funny here.

I also went to the Greater Boston R user group meeting on July 28. Amy Szczepanski gave a talk on doing High Performance Computing with R which was a great talk. I enjoyed how she went through the evaluation and decision making process for implementing HPC. I had never seen anyone do that in this format, and it was very well done. Amy travels a quick a bit, and I would strongly encourage other R groups to get her on their meeting calenders!
