Yesterday, I was putting away groceries, and I turned for some reason, and I felt a now familiar twinge in my back. I had strained a muscle in my back, much as I have done a few times in recent months. It hurt a *lot* last night, and somewhat less today. I’m hopeful that I’ll be more or less normal later in the week, and I can get back on my running schedule, but I’ll have to take a few days off to recover.
Today I’ve been working on Project Euler problems: I did a few of them a couple years ago, and I’m re-doing those in C, rather than Ruby.
