This blog is going to be shutting down temporarily starting Oct. 1 to allow for the transfer from an MIT to a USC server. We expected to be fully operational again in a few weeks time. During the down time, it is my belief that you will still be able to access old posts but will not be able to make new comments and I will not be able to update the blog's content. Sorry for any disappointment this may cause anyone, but it is part of the process of my move from East to West Coast. I will still be posting links and tips regularly to my Twitter followers. Otherwise, this will give you a chance to catch up on the rich backlog of material that we've accumulated around the blog over the past few years. See you soon.
