URL Shortener Followup

With the current trend in URL shorteners, it's difficult to make sure what url redirects where, such as whether or not that tinyurl link leads to one of those shock websites.
A few years back Twitter offered and announced its t.co url shortener service that is now the standard URL shortener for all of twitter's link, making projects like this useful: http://tweeplus.com/#

However, at the same time, Twitter had made raw links quite ambiguous - for example: http://t.co/uUiGMyzFIH

Basically, what I have created is a once-only URL followup, or to be more concise to its objective, a "URL Shortener Followup", which is a simple web tool that it analyses your link once, to see where a URL will redirect to.
This concept has most likely been thought about years ago, however this followup tool is unique in that it will only attempt to detect any redirects exclusively from your URL and not attempt to follow up or send a request to any secondary URLs that your link redirects to, keeping links that have a certain expiration time or secret token(s) confidential and untouched.

iOS 7 Beta 1 Compass Fix

As a beta, iOS 7 is amazing, however, there are quite a few issues that will be hopefully resolved in the final version of iOS 7.
The compass app may not work on your iPhone as it may get stuck on "Complete the circle to calibrate" whenever you open up the compass...

Re enabling input elements with javascript

Throughout my experience with HTML and javascript, re enabling input elements with javascript is an issue that has really caught me off guard, and one of the main reasons as to why I put off using disabled inputs.

Basically, every single time I attempt to create a script that will disable and enable an input button (as in making a button unclickable and clickable), I end up creating code that looks something like this:

document.getElementById("button1").onclick=function(){
    document.getElementById("button1").disabled="true";
}
document.getElementById("button2").onclick=function(){
    document.getElementById("button1").disabled="false";
}

and it has never worked, as much as I would like it to - despite the fact that setting "disabled" to be false should enable the input element.

Searching Google reveals this question on Stackoverflow: http://stackoverflow.com/q/6835165/1756941, which has an answer that does not meet StackOverflow's guidelines and expectations (ie. a link-only answer).

To make the code above work as intended is simple, and the solution is actually very simple.

just remove the quotes... And that's it!

Demo:

Code:

document.getElementById("button3").onclick=function(){
    document.getElementById("button3").disabled=true;
}
document.getElementById("button4").onclick=function(){
    document.getElementById("button3").disabled=false;
}

This is because the disabled attribute on an input element is a boolean, and text is always considered to be true. However you can find this out yourself!

Demo:


Code:

document.getElementById("button5").onclick=function(){
if ("false"){alert("\"false is true! (as a string)\"");}else{alert("\"false is not true! (as a string)\"");};
if ("false"==true){alert("\"false is true! (compared to true)\"");}else{alert("\"false is not true! (compared to true)\"");};
}

This seems illogical, as even as a text, false should be considered as false, especially when set as an attribute, but then again. This is javascript we're talking about...
