ES6 Realms API

Notational Conventions

This section describes the conventions used here to describe type signatures.

A [T] is an array-like value (only ever used read-only in this API), i.e., one with an integer length and whose indexed properties from 0 to length - 1 are of type T.

A type T? should be read as T | undefined -- that is, an optional value that may be undefined.

post about Node.js, non-blocking I/O and the event loop

#Node.js and the Event Loop

Node.js is a framework for writing server-side JavaScript applications. It is built on top of the V8 JavaScript runtime and uses an event-driven, non-blocking I/O model that makes it perfectly suited for data-intensive real-time applications.

This blog post will describe what non-blocking I/O means and how working with the event loop can help your applications be more efficient.

##The Restaurant

"This [non-blocking I/O] model simplifies access to slow resources in a scalable way that is intuitive to JavaScript programmers and easy to learn for everyone else." - Node Up and Running.

Get the average colour of an image in javascript using getImageData in CANVAS
function getAverageColourAsRGB (img) {
var canvas = document.createElement('canvas'),
context = canvas.getContext && canvas.getContext('2d'),
rgb = {r:102,g:102,b:102}, // Set a base colour as a fallback for non-compliant browsers
pixelInterval = 5, // Rather than inspect every single pixel in the image inspect every 5th pixel
count = 0,
i = -4,
data, length;
// return the base colour for non-compliant browsers
//
// Regular Expression for URL validation

Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo.
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh

Remove file extensions in URLs with mod_rewrite but preserve 404 errors.
# The following will allow you to use URLs such as the following:
#
# example.com/anything
# example.com/anything/
#
# Which will actually serve files such as the following:
#
# example.com/anything.html
# example.com/anything.php
