HTML5 and friends.

A bigass bulleted list of features.

I commonly need to get a big list of all the stuff people think of when they think new and shiny these days. This list is for that.

I take a very inclusionist approach to it. 1

• Web Storage (localStorage, sessionStorage)
• Web SQL Database

# Rails developers have long had bad experiences with fixtures for
# several reasons, including misuse.
# 
# Misuse of fixtures is characterized by having a huge number of them, 
# requiring the developer to maintain a lot of data and creating dependencies 
# between tests. In my experience working (and rescuing) many applications, 80%
# of fixtures are only used by 20% of tests.
#
# An example of such tests is one assuring that a given SQL query with
# GROUP BY and ORDER BY conditions returns the correct result set. As expected,

// Run the function as soon as it's called, but prevent further calls during `delay` ms
// Example: function.throttle(200) will only run function() once every 200 ms.
// Useful, for example, to avoid constant processing while typing in a live search box.
Function.prototype.throttle = function(delay) {
  var fn = this
  return function() {
    var now = (new Date).getTime()
    if (!fn.lastExecuted || fn.lastExecuted + delay < now) {
      fn.lastExecuted = now
      fn.apply(fn, arguments)
