Bookmarklets

A what?

A bookmarklet is an applet, a small computer application, stored as the URL of a bookmark in a web browser or as a hyperlink on a web page. The term is a portmanteau of the terms bookmark and applet. Whether bookmarklet utilities are stored as bookmarks or hyperlinks, they are designed to add one-click functionality to a browser or web page. When clicked, a bookmarklet performs some function, one of a wide variety such as a search query or data extraction. Usually the applet is a JavaScript program.

From Wikipedia

Projects is home to three bookmarklets at the moment: GUID Generator, Mailinator and LMGTFY. Links for both can be found below, along with an explanation of what each does.

GUID Generator

GUIDs are useful. That's a fact. You can use them to identify all sorts of stuff, from code snippets (as per Coding Horror's suggestion) to CDs (a la CD keys). The best part? There are 3.4x10³⁸ different keys. Yes, that's the number 34, followed by 37 zeroes. Wikipedia comes in handy again: For example, consider the observable universe, which contains about 5x10²² stars; every star could then have 6.8x10¹⁵ unique GUIDs. (wikipedia.org/wiki/Globally_Unique_Identifier)

Mailinator

Spam is a problem. That's a fact. As a result, pages like Mailinator and Dodgeit have popped up, which serve as temporary email addresses using whatever name you want. For details, check out mailinator.com.

So, what does it do? This bookmarklet first pops up a prompt asking for a mailbox name. It doesn't have to exist, or it could be one of your "regulars." It really doesn't matter. Next, if you have a textbox selected, the address is pasted into the box. If you have anything else currently selected, the script opens a small window showing the mailbox.

LMGTFY

Let Me Google That For You lets you deal with the annoying questions the easy way, hopefully teaching your lazy friend a lesson along the way. This little script asks for the Google query you'd use, and then shows a link to the LMGTFY "search" for that query. Simple but effective.

Formatting:
[b] for bold, [i] for italicized text, [u] for underline, and links are [url=link]Text[/url] or [url]link location[/url]
