Today I got to close the library by myself! I was a little bit anxious, but things turned out okay in the end. Things picked up a little bit about half an hour before closing, but it never got really backed up at the desk. Though I did have some patrons come in 2 minutes before closing. They were nice though, got in and got out fairly quickly, so I ended up leaving only about 10 minutes after closing (though most of that was due to my own paranoia and obsessive list double-checking).
I realized, as I was in the parking lot, that I had forgotten to turn off the lights in the bathroom, so I had to go back in and
brave the beeping alarm turn them off. All in all, it was only a little oopsie, and since I remembered before I left for good it hardly counts, right?
Just barely made it back in time for our 7505 guest speaker, Cliff Landis! He seems like a pretty good guy, and he definitely knows his stuff. After the class meeting, I spent a little bit of time looking up the various explanations of cloud computing, because it seems to be a very debatable term. CC appears to be similar to a LAN with online data storage, though I know that's something of an oversimplification.
I'll get back to schoolwork tomorrow, for now it's time to clean house!

Cloud computing is when you use virtualization to turn a data center into a generic computing resource. In other words, I used to have this giant data center of machines, and then I turned every machine into a host for virtual machines, so I can suddenly use this data center for whatever I happen to want at the time, including online data storage. Things don't have to be online data storage, but that's what the most famous uses of them are. We are currently storing our blogs on Google's cloud, for example, and their cloud is just these huge warehouses full of servers that they can use for whatever they want.
Fun fact: the past three defenses in my research group have all used this really cool CC picture of a cloud in a box, and none of us cited it, because we all stole it from one guy who forget where he found it.
