Surely You're joking, Mr. Feynman!

Learn what the rest of the world is like. The variety is worthwhile.

"I could do that, but I won't" -- which is just another way of saying that you can't.

You don't have to be responsible for the world that you're in.

You have no responsibility to live up to what other people think you ought to accomplish.

• expression: syntax, type-checking, evaluate
• REPL: Read, Evaluate, Print, Loop; do not type use without restarting REPL
• syntax:
  • negation: ~5
  • division: div
• after expression evaluated, the expression producing the result is irrelevant --> do not reuse use in sml
• access pair/tuple: #1 e
• naming:
  • pair <--> pr

Learn C the hard way

• switch statement:
  • return 1 --> tell OS there's an error
  • only integers allowed (eg. char)
• use functions
  • forward declaration: use function before defining them
• pointers

Miscellaneous

• I wrote a small utility to manage my "My Clippings.txt" from Kindle. This script will create a separate note for each book.

• gist is an awesome command line tool for gist.

• use rlwrap sml to enable history rollback through arrow keys
