Bought a new Western Digital 750 GB hard drive for my laptop, and an enclosure for the original 160GB drive, which I'll now use as a Time Machine backup for my Swat Macbook Pro. (I have 3 laptops, I now have 3 back-ups). By dint of my Swat machine not having an insane amount of music on it, 160GB will be plenty of space to back up all the research I could ever imagine myself doing. I loaded the new 750GB drive with my latest Time Machine backup, and aside from the fact that TM doesn't recognize that this computer is the same as the one it was two hours ago and is now doing a backup from scratch that will take hours and eat up a ton of space, everything is fine. (This is apparently avoidable with a few terminal commands, but it seems like a pain and it's really no big deal.) Dropbox and Google Drive also didn't recognize that the computer is the same, but that was as simple as logging in again.
In conclusion, I'll never again have to bother deleting movies and TV shows I've already watched, despite the fact that I have no intention of every watching them again. And I can create a partition on the hard drive that boots into Ubuntu, because that's what the cool kids do.
Taught students about Bayes' Theorem in stats and Hall and Jones' paper on social infrastructure and income levels in development today. The development students aren't required to have any stats training, so it's daunting (foolhardy, most likely) to try and explain regression, multiple regression, endogeneity, and instrumental variables all at once to students who have never seen any of that material before, but hopefully there are enough examples throughout the semester that it'll become clear by the end.
