"Brrrr!", "Yes!" and "Youch!"

• Attended both lecture and lab classes again of our automata course. This time I brought along a sweater to wear in that ridiculously freezing lab room. It didn't do much good though. Maybe I should bring my winter coat next time! Have a good mind to bring along a thermometer too just to find out exactly how cold it is in there!
• I worked on the exercise given during said lab in my office. It was fun figuring things out on paper instead of using JFLAP. In fact, I believe I correctly answered all three problems.
• What a horrible scene on Centre Court at Wimbledon: del Potro chases down a volley from Ferrer in the very first game of their quarterfinal match, stumbles then hyperextends his (already heavily wrapped) left knee! Quite a relief to see him bravely soldier on and produce a happy ending by winning the match in straight sets.
