Something miraculous is happening right now: I've figured out how to flush my entire drive and install an operating system. But this time, it's not OSX Mavericks: it's Yosemite, the newest OS.
Although I'm pissed off that I'm going to have to reinstall all my lost programs (Photoshop, Word, Acrobat, Firefox, Chrome, etc.), I'm happy that I'll be up and running again in just a few minutes, and I'm hopeful that whatever malady had struck my computer has been scoured away in this great cleansing.
As Sam said in "Battlestar Galactica," see you on the other side.
