JResig: Learning from Twitter <http://ejohn.org/blog/learning-from-twitter/>

	/*
	It's a very, very, bad idea to attach handlers to the window scroll event. Depending upon the browser the scroll event can fire a lot and putting code in the scroll callback will slow down any attempts to scroll the page (not a good idea). Any performance degradation in the scroll handler(s) as a result will only compound the performance of scrolling overall. Instead it's much better to use some form of a timer to check every X milliseconds OR to attach a scroll event and only run your code after a delay (or even after a given number of executions - and then a delay).

	Always cache the selector queries that you're re-using. It's not clear why Twitter decided to re-query the DOM every single time the scroll event fired, but this does not appear to be necessary (since scrolling itself didn't change the DOM). They could've saved the result of that single query to a variable and looked it up whenever they wanted to re-use. This would've resulted in absolutely no querying overhead (which is even better than hav

geraldyeo / promisify

Created September 29, 2013 23:26

<http://howtonode.org/promises> The majority of functions that take Node-style callbacks are suitable for wrapping in a Promise. Any Node-style callback function that only calls its callback one time may be wrapped. The following function is taken from Bogart.

	function promisify(nodeAsyncFn, context) {
	return function() {
	var defer = q.defer()
	, args = Array.prototype.slice.call(arguments);

	args.push(function(err, val) {
	if (err !== null) {
	return defer.reject(err);
