In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
  // Fork workers.
  for (var i = 0; i < numCPUs; i++) {
    cluster.fork();
  }
  cluster.on('exit', function(worker, code, signal) {

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

jrust

This is a fork of a fork of Bootstrap Typeahead that adds minimal but powerful extensions.

• Ability to disable autoselect of first matched element.
• Ability to automatically set the width of the dropdown to that of the text input.
• Ability to fetch source element via AJAX
• Ability to have a comma separated list of tags.

For the proper source, and other examples, please see the original gist.

Example showing off all the above features

class Lisp
  def initialize
    @env = { 
      :label => lambda { |(name,val), _| @env[name] = val },
      :quote => lambda { |sexpr, _| sexpr[0] },
      :car   => lambda { |(list), _| list[0] },
      :cdr   => lambda { |(list), _| list.drop 1 },
      :cons  => lambda { |(e,cell), _| [e] + cell },
      :eq    => lambda { |(l,r), _| l == r },
      :if    => lambda { |(cond, thn, els), ctx| eval(cond, ctx) ? eval(thn, ctx) : eval(els, ctx) },
