What hashing function they use?

A case-insensitive variant is Base36:

I remember you being a Lisp programmer; it's built into CL's Format function:
(format t "~36r" 9999) ==> 7PRNice simple public stats: http://goo.gl/info/Jvhu#two_hours Not a huge fan of the flash chart though. http://goo.gl/Jvhu http://goo.gl/Jvhu.qr EDIT: Better graph
Strange... : I clicked in the above url. Then I copied the resulting url ( http://www.magicbeef.com/ ) After pasting it in google service, it produced a different short url: http://goo.gl/YH1c I first assumed that every destination would render an unique short url, but thats not the case. This way google knows the full stats of http://www.magicbeef.com/ . But you can only know the real stats if you know ALL the short…

Earlier they did not offer custom URL shortening. goo.gl was used by Google services like Reader, YouTube but it was not open to public.
Hm but with that Chrome extension, it worked. So I guess there was an open API already.

We don't need them. Companies that create the shorteners need them to collect information about who clicks on your links. That, and there's a service out there that limits updates to 140 characters.
We do need them. While twitter pretty much spawned the whole ecosystem, there still is a very important and functional use for URL shorteners. The biggest, outside of twitter, has to be the method of emailing enormous html links to someone. With so many email clients out there, it is a crap shoot to send a link. Personally and professionally bit.ly has really helped out in those cases. With that in mind, I wonder wha…
All goo.gl URLs and click analytics are public and can be shared by anyone.
Ugh. Google entering this pretty much wipes out the space - companies like bit.ly are going to need to work on seriously differentiating themselves from the pack, and even then I don't think they're long for the world. I can honestly say I hope to never be in a market - or working on a product - where google suddenly decides to enter the game. Even if their offering sucks, or is broken, it sucks all the air out of th…
Why do we need url shorteners again ? When I see a shortened URL the probabilities of me clicking the link go down to almost zero.

[edit - Nevermind, solved below in the comments.] Does anyone know how these work long-term? This one shortens a URL to 4 characters, so for a potentially major URL shortener, there is a relatively low number of possible outputs. Once they hit their limit, do they start erasing the oldest ones? The most inactive ones? For shorteners that give consistent shortened URLs (i.e. everytime you shorten the same input URL, y…
> Once they hit their limit, do they start erasing the oldest ones? The most inactive ones? Let's do the math. If we assume that a service only uses a-z, A-Z and 0-9 as characters for the shortened URL, we have a set of 62 characters. /x -> 62 /xx -> 62^2 = 3,844 /xxx -> 62^3 = 238,328 /xxxx -> 62^4 = 14,776,336 /xxxxx -> 62^5 = 916,132,832 /xxxxxx -> 62^6 = 56,800,235,584 In the worst case scenario, the URL shortene…

Last I tried, I could send an email formatted in HTML, where:
