MetaDesktop

One of my current interests is in AJAX programming. To that end, I’ve decided to develop the basics of a lightweight web “operating system.” I’m calling it MetaDesktop mostly because it’s goal is to be a quite literally a meta desktop that is able to run on a number of different servers and platforms. It’s almost entirely client-based, with as little server-side communication as possible. The server-side portion of the system could theoretically be implemented in any scripting language that is capable of accepting URL-based (“query string”) parameters and can produce HTML/XML output. It is my eventual goal to maintain two separate server-side implementations in ASP.NET or ASP and in PHP.

To put it succinctly, MetaDesktop has the following goals:

Platform Availability. Work in all major browsers, and on all major server/scripting platforms. There will eventually be separately maintained server portions of the program in PHP, ASP/ASP.NET, and maybe even other languages if I decide to learn them (or someone contributes them!).

Speed. A lot of server communication can lead to a very slow user experience. I aim to put as much of MetaDesktop on the client-side as possible. This raises a whole host of interesting problems (and in problems are learning opportunities!) such as dealing with concurrency in a language that has practically no support for it.

Compatibility. I want the system to be completely compatible with applications that run under other web desktop systems such as eyeOS. Many of these systems use a mainly server-side approach to write applications. That is, the server-side scripting languages produce the necessary JavaScript to show on the client. Since MetaDesktop is client-centric, this provides an interesting opportunity to learn how the technologies would interact. This is quite possibly the most lofty goal I have for this project and won’t be tackled for a long, long time if ever.
