How to Survive This Class
I want this class to be as enjoyable as possible. That’s the best way to learn. But here’s how to avoid dark and desperate moments.
-
Learn to type. If you don’t know how, it will slow down everything else.
-
Here’s a test. (My best score is in the 100 words-per-minute range.)
-
-
Start assignments early.
-
Work frequently and often.
-
Schedule time to attend office hours with your partner. I’d suggest at least 4 hours per week, but more is better.
-
Pair program with your partner:
-
One person hacking, the other observing.
-
You do not want to introduce bugs into your kernel.
-
-
Liberally use
KASSERT. -
Write tests.
-
Find a way to iterate quickly and limit the number of untested lines.
-
Break your code into small, easily tested functions.
Next Time
