It appears that everyone From The Internet lives in California.

Ask them what the length of a vector is.

2000 food calories/day ≈ 100 watts

Normal People Things:

  • Gone to a party unrelated to my family.

Never thought I'd do:

  • Worn a t-shirt with text on it.
  • Written an essay structured using a gratuitous extended metaphor.

Extra nerd points:

  • Programmed a number type which carries units and error values, to reduce the tedium of lab reports.
  • Learned to write all my assignments in LATEX.

Java programming class (yes, I know Java already) today, introducing loops. Task: write a factorial program. I wrote mine to use int arithmetic if possible, floating-point if not. Test the edge cases, of course. It says:

500! ≈ Infinity

I'm glad I used the “approximately equals” sign.

I get the feeling the textbook writers had a list of everyday objects which they randomly picked from to avoid saying “an object” in each exercise. The results are mostly just distracting or mildly amusing, but sometimes they're a bit too much:

Sample Problem 9-6One-dimensional explosion: A ballot box with mass m = 6.0 kg slides with speed v = 4.0 m/s across a frictionless floor in the positive direction of an x axis. The box explodes into two pieces. One piece, with mass m_1 = 2.0 kg, moves in the positive direction of the x axis at v_1 = 8.0 m/s. What is the velocity of the second piece, with mass m_2?

While setting up my new laptop, I found this situation:

I had three mounted volumes all named kpreid. Luckily, they were of different types so they could be distinguished by icon.
