My App Engine “Wall”

Filed Under geeky, technology 

I was messing around with Google’s App Engine this week, and learning some Python (the programming language, not the snake! I had someone ask me that) at the same time.

App Engine (for scalability reasons) does not support SQL, but instead provide and API they call Datastore for persistent storage. For the app I made, I queried for data ordered by date, but for some reason the result set still comes out unordered. Odd. I’m probably not calling it right. Anyway, it was just an exercise to see what App Engine was all about.

Here’s a replica of the Facebook Wall I made, feel free to write your heart out. As you can see, I’ve had friends say some really nice things about me already. The full address is liew.appspot.com .. but there’s an iframe to it if you’re too lazy to click on that link :)

Update 6/15/2008 — Tinkered around a little and realized why its unordered .. I lost the timestamps on some of the posts, so for those that come out unordered, it’s because there are no records of which came first (the timestamp was NULL). It should be fine going forward. The un-stamped posts take precedence in ordering over the stamped ones, so you may have to scroll down a little to see your post (or just CTRL-F it).
