I don’t really pay attention to twitter that often,but I did notice more and more people are starting to use personalized url shorteners. There’s a lot of free services out there you can use, but if you have somewhere you can host a simple php script, why not make your own?
I ended up buying iamj.us/tyn, and that’s what I’m going to set this up on. If I wanted to make things shorter, I could take off the /tyn but then I dont think it’d make as much sense. http://iamj.us/tyn11l redirects back to this page, for example. If you need help picking out a short domain name, try out domai.nr.
To create my own shortener, I decided just to use php’s base_convert function which will convert to and from bases 2-36. For a personal url shortener, you shouldn’t need more than base 36. I did end up having to write a base 62 converter class for sh0tz so that I can keep urls short, but that’s another post another time.
