Search wars hit desktop computers. Another front in the on-going battle between Microsoft and Google is about to be opened. By the end of 2004 Microsoft aims to launch search software to find any kind of file on a PC hard drive. The move is in answer to Google's release of its own search tool that catalogues data on desktop PCs. The desktop search market is [OSNews]

Under Gmail's hood.
I'd been experimenting for a few months with Gmail, Google's Web mail system, without really taking it seriously. But this week I decided to take the plunge and try using Gmail not only as a mail search engine, but as a replacement for Outlook (on Windows) and Mail (on OS X). Now I'm ready to join the chorus singing the praises of GMail[base ']s user-interface technology. Its combination of HTML, JavaScript, and the DOM makes the browser do some remarkable tricks.
...
As early adopters discovered long before I did, there's an architecture behind this JavaScript/DHTML wizardry. The best description I've found is from Johnvey Hwang, who deconstructed Gmail's JavaScript code and created a .Net-based Gmail API. As Hwang described in his July 5 write-up, Gmail loads a JavaScript UI engine into your browser at the beginning of each session. Oddpost, he noted, was the first Web mail application to perfect this technique. That was a prophetic statement: Just four days later, on July 9, Yahoo acquired Oddpost.
Because Gmail's behavior is embedded in the UI engine, all subsequent interaction between the browser and the Gmail service is just an exchange of data. What Hwang calls the DataPack format is not XML, though; it's JavaScript. When you make a request to the Gmail service, whether to refresh your inbox or to modify the list of labels you can attach to messages, the response is a minimal set of JavaScript function calls and associated data objects that the engine uses to update the display.
...
So is Gmail a rich Internet application? Sure. Although that label most often applies to Java, .Net, and Flash clients, Gmail shows that Web clients can join the club too. But crucially, Gmail's architecture is open to other kinds of rich clients, too. It doesn't have to be a zero-sum game. [Full story at InfoWorld.com]
