So a few days ago, my computer stopped working. The preliminary diagnosis is a defective NVIDIA graphics processor failing. The good news is that I won't be charged for the new motherboard this fix entails. The bad news is that my computer will be in the shop for a week, possibly more. I should be able to send and receive email -- but I won't be able to check as regularly, and it's likely I'll respond even more slowly than usual. And it's absolutely certain I'll be grumpier than normal for the next week, but I'll try not to spread it around.
