If you've been running Windows along side Linux using Grub and grub starts failing, or you decide to stop dual booting to run only windows and aren't smart about it, or you remove a disk grub thinks is supposed to be there but you don't really need to run e.g. Windows, you're likely to get stuck in Grub. Googling for "grub error 17" and "grub error 15" or just "grub error" brings you a lot of posts made by Windows users in various states of panic. If you're like me and also forgot where your Windows CD is or just forgot your administrators password, that you need for repair, you'll be happy to know that Gag has your back. Download. Locate the ISO file and burn to CD from some other computer. Boot from that and you should be able to get to your Windows partition. Menus in Gag aren't maybe the most straightforward but it works.
The IronPython screencast in Jon Udell's pioneering series of screencasts is great and points out how we live in really interesting times programming wise. With deep integration between good dynamic languages and decent compiled languages we're truly going places. There are several options between the JVM and the CLR (and who knows, maybe some day even Parrot), but IronPython is certainly a good candidate for where to enjoy this kind of privilege. Shame about the operating system.
I'm totally digging Sam Ruby's personal recommendation engine. It shows off trends I believe will only increase in proportion - specifically that data density and remix density is important and that the future of clock cycles is to run pattern recognition algorithms.
That the purpose of the hack is to bring the world closer to one of my own personal goals is just an added bonus.
