TechEd 2007 - Building Fun, Cool Applications with Popfly

Building Fun, Cool Applications with Popfly
Dan Fernandez
First time I tried Popfly I didn't like it too much. But I gave it a change by learning more about it in this session.
There was a lot of people in this session, too much people actually. I had to attend to it in another room, with an bad streaming quality...

The main idea is to democratize development over the internet. Allow people with almost no programming experience to create rich content websites. Dan used a great analogy. The difference in the number of programming experts and people that doesn't know how programming is like difference between the size of the Sun and the size of Saturn. Actually, after seeing his demonstration, I wasn't convinced than Popfly is really a tool that can be used by every one... Is more like a toy for programmers :-P

In his first demo he showed how to display a bunch of Flickr photos in a carousel and in a virtual book.
He showed how mashups (small visual) can be exported to Windows Vista Side Bar, Live Spaces, Facebook, or even to an simple HTML page. These mashups are actually Silverlight applications.
He also built an popularity comparer, that with two search terms creates a comparison graphic with the number of results in a search.

Dan also showed us how to create Building Blocks, which are the components which are combined to build mashups. It uses javascript to code behaviour and XML to store metadata like the kind of input/output that the block takes, and some suggestions about compatible blocks that can be combined with our costume one.

Pretty nice, hum?
