Dynamically add CSRF protection <input>s to each form on the page immediately before it's submitted. This code uses MooTools, though it would be trivial to remove that dependency or swap with jQuery.
var CSRF = (function() {
window.addEvent('domready', function() {
/**
* Setup triggers on the .submit() function and the `submit` event so we
* can add csrf inputs immediately before the form is submitted.
*/
$$('form').each(function(form) {
// Ensure all forms submitted via a traditional 'submit' button have
// an up-to-date CSRF input
form.addEvent('submit', function() {

Unlimited size uploads in PHP: a minimal demonstration.

Unlimited upload size in PHP

a minimal implementation

A demonstration of accepting unlimited-size uploads in PHP. The included server.php pipes the POST body directly to /dev/null and returns a JSON encoded hash of some useful stats. Using this method (streaming from stdin) we are able to accept uploads of any size with little memory overhead.

Setup

Symlink apache config and reload

Allows easy composition of a chain of connect.js-style middlewares
// Allows easy composition of a chain of connect.js-style middlewares in node.js
// given:
// function A(req,res,next){}
// function B(req,res,next){}
// composeMiddleware(A,B) will return a function(req,res,next) that passes the request
// through both handlers, just like Connect. If a next() is called with an error
// the call chain is stopped and the error is passed to the topmost next()
// If next() is called with the second parameter set to 'break' "next(null, 'break')"
// The chain is halted and route control is passed back to the original next()
