Jason Cline, from SitePen, posted about his chat app on the iPhone. It uses the Dojo toolkit, and Cometd.
Cometd has been tested on the iPhone before, but this one was custom made for it. Great job Jason.
It's nice to see my project (Cometd) being used for some cool apps!
I've been working on an inter window communication javascript library based on javascript built for Vox. This allows browser windows or tabs on the same domain to communicate and cooperate. One use case for this is for comet connections. Due to self imposed browser limitations, multiple connections to the same domain are limited to two connections and comet connections would produce odd behavior when multiple windows or tabs are opened on the same domain. This is the first step in efficient use of a single comet connection across multiple tabs or windows. This library would be used with another project of mine: Cometd: The Scalable Comet Framework

Note: Currently this only works in Firefox 2 and IE 5.1+
The IE background flash has plagued web developers for quite a while. There are a few things that cause this, and you can read about it here, Basically, when you hover over an element with certain properties, IE will ask the server if it has been modified, and the background image will flash.
All the existing solutions to this problem have been either css hacks or server side changes to image expiration.
Dan POPA has found a javascript solution:
try {
document.execCommand( "BackgroundImageCache", false, true );
} catch( e ) { };
wow
I combined a force directed graph and FOAF (Friend of a friend) to create a Visual Friend Explorer
It needs some work, but it works! :)
Perhaps I'll create a tag explorer next...
Here's a sneak peek into my javascript graphing component.
Pictured above are 3 data sets. The two on the right are added to the graph on the left. The datasets can be taken from a file or a JavaScript object and only takes a few lines of code to produce these graphs.
The graphed data is taken from another graphing system. I want to make sure that my graphing logic matches a working system.
I've done this in my spare time and it needs more work, but it's looking great. This is a screenshot of a browser window. Those windows are actually inline dhtml windows. (Part of another project I am doing)
This can be combined with my ShortBus project to provide a constantly updating set of graphs based on any data!
Planned:
- Live graphs
- Zoom tool
- Pie and bar graphs
- Resizable graph canvas
