Web design path

  • [HTML][html]
  • [CSS][css]
  • [JavaScript][javscript]

You can stop there if you only want to learn basic web design. If you want to make web-apps and stuff, these are highly recommended:

  • [Ruby][ruby]
  • [Sass][sass] (think of this as super-powered CSS)
  • [CoffeeScript][coffee] (think of this as super-powered and better-looking JavaScript)

This is quite a useful improvement over the regular Javascript setInterval()
# Usage:
# every 250, (stop) ->
# stop() if condition
# # some logic...
#
# Still preserves original behavior if you want to do that:
# interval_id = every 250, someFunction
# clearInterval(interval_id)
every = (time, fn) ->

COP 3503 Review

Hash tables

Linear (and quadratic) put and get

public class LinearHashTable {
  void put(DataStruct ds) {
    // For the test, we don't have to worry about table expansion.
    int hv = getHashValue(ds.getKey());
