Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

define(function(require) {
    var React = require('react');

    var paramRegex  = /__(\d)+/;
    var parser      = new DOMParser();
    var errorDoc    = parser.parseFromString('INVALID', 'text/xml');
    var errorNs     = errorDoc.getElementsByTagName("parsererror")[0].namespaceURI;

    // turns the array of string parts into a DOM
    // throws if the result is an invalid XML document.

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

This all applies to Ruby 2.1. In some cases a setting is not available in 2.0, this is noted. There is also a different with 1.9, 1.8, and REE --- these are not noted.

All the relevant code is in https://github.com/ruby/ruby/blob/master/gc.c

RUBY_HEAP_MIN_SLOTS

default: 10000

The number of heap slots to start out with. This should be set high enough so that your app has enough or almost enough memory after loading so that it doesn't have to allocate more memory on the first request (althogh this probably isn't such a big deal for most apps).

(todo: figure out how big a slot is. i think the answer can be infered from this code.)
