MooTools Forge

MooTools.net has a nice new feature, called Forge. It's a code repository for developers who are willing to share their MooTools based projects. At this time, it has only 36 scripts, but I'm sure, that this will be multiplied in a shot time, check AjaxRain.com for instance. It's a great collection of scripts, but it's uncontrolled.

What I like about MooTools Forge, is that they give you a guideline on how to publish you code. The first step is posting the project into GitHub, then you have to add a simple "yml" file to describe your package. You can even define the dependencies. Read more here.

It does 4 things at a time: provide documentation, example codes, demos and download opportunity. Official MooTools projects will be stored here also.

Konami codes in javascript

If you ever played any platform, fighting or combat games like Contra or Mortal Combat, then you will be familiar with the special key combinations for executions or special attacks that gives you some extra power, effect, or god mode. The Konami code was one of the fist cheat code in the video gaming history, that special combination later adapted by many games.

In the age of websites, many sites also installed small easter eggs for their visitors, just for fun. See the list here.

I played a little with implementing it, and just a few rows were enough to achieve the desired effect.

var p = 0;
var order = [38,38,40,40,37,39,37,39,66,65];
document.onkeyup = function(e)
{
	var key = (window.event) ? event.keyCode : e.keyCode;
	p = (order[p] == key) ? ++p : 0;
	if( p == order.length ) alert('Boom, secrets unlocked');
};
