2. I’m living in China within the famous GFW, and I’m using a twitter proxy site to tweet when I’m at home or using mobile phone.   So there is a problem to me, the http://bit.ly is almost the most popular short url service on twitter which is also blocked by GFW…

3. There are some short url expanding service sites, like http://longurl.org, but they were blocked sometime…

I decided to create a simple function with google app engine after dinner. So that I can continue to learn some of python and also know a little of google’s cloud stuff.

Then here you go the app: http://yatlongurl.appspot.com/ and the source code here. Really quite fun to write code with python. But it looks the app will be intermittently unavailable. And apparently, I did not use any of real functionalities of google’s app engine. Possibly I will add support to automatically retweet or delicious the useful link while expanding it .
