Two birthdays and an exam

• Today is the 32nd birthday of my favorite tennis player, Roger Federer the Great! Happy happy Birthday, Roger!  It's also the birthday, so to speak, of my MacBook Pro which turns three today. Nice to see that both are still performing well and going strong. Ha, ha.
• We took our midterm exam in our formal languages, automata theory and computation course. Having taken nearly three hours to answer it (we were allotted two hours), I'm mentally and physically drained. And, although I have lately realized that some of my answers are possibly incorrect, am very much relieved it's over. Hey, at least I had answers which is actually more than I could hope for, having not previously taken the prerequisite undergraduate course!
