Semi-ambidextrous

Saturday, January 31st, 2009

I’m technically left-handed, but surprisingly enough, I almost always use my right hand for more physical activities. Recently, another left-handed person I know attested to this behavior as well. It’s not ambidexterity, but it is a pretty interesting phenomenon. Seems as if my left hand is the smart, sensitive one and my right hand is.. the guy who knows how to play sports. Well, they both have their subtleties.

Left handed

  • Writing and Drawing
  • Eating (Forks & Spoons)
  • Billiards

Right handed

  • Baseball, Basketball, Ping Pong, Frisbee, Tennis
  • Using a Computer Mouse
  • Brushing Teeth
  • Trombone
  • Aiming Things (i.e. Archery)
  • Arm Wrestling
  • Carrying Large Things

The Ostrich Algorithm

I found this on Wikipedia and thought it was hilarious. “Stick your head in the sand and pretend that there is no problem” is quite an algorithm. Actually, I think I’ve used it in my systems programming labs before.

CMU Spring ’09

Friday, January 30th, 2009

Two weeks into the new semester, and things are getting interesting. My schedule:

  • 15-212 Principles of Programming
  • 15-213 Introduction to Computer Systems
  • 15-451 Algorithms
  • 15-453 Formal Languages, Automata, and Computation
  • 76-383 Multimedia Authoring II

Four heavy-duty CS courses and one Flash/Actionscript-based course. I’m pretty happy with that.

15-212 is basically functional programming in SML, a language I have never heard mentioned outside CMU. Ever. The underlying principles should be the same as those of more “popular” functional languages (like Lisp, Scheme, or Haskell), but come on now. Esotericism has its limits.

Here’s something interesting: 15-451 is being taught by Manuel Blum and 15-453 is taught by Edmund Clarke. They both happen to be Turing Award winners, which is like.. whoa.

So how do they stack up as teachers?

Well, actually, not particularly great. They are by no means bad, just not outstanding. After a second of consideration, this isn’t all that surprising. I’d even guess that strong research would have a negative correlation to undergraduate teaching quality, because spending time on cutting-edge research usually doesn’t get passed on to undergrads. I could be overgeneralizing, but this seems to make sense.

Blum and Clarke are old guys. They’ve got well-developed beards. We all know how old professors can be a bit out of touch when it comes to students. Still, the stuff they’re teaching makes up for it. Finite automata have been downright fascinating so far, which is not at all what I expected.

Should be an interesting semester.
