XHR Chat is a demonstration type chat script I wrote when experimenting with xmlHttpRequest. It never refreshes, keeps an infinite post log, and checks for new posts once a second.

XHR Chat will degrade gracefully if the browser doesnt support xmlHttpRequest, just so long it still has javascript enabled.

Enhancements:
- hash_maps are now used instead of maps, so the cost of lookup or insertion is O(1) in the average case, instead of O(logn).

IRC-Chess project is a 2-player chess game for IRC which turns a computer into an IRC chess bot.

It consists of a Java chess server, with frontend scripts to convert an IRC client into a chess bot. Players then communicate with the bot using standard IRC commands, and dont require any special software to play.

Frontend scripts are available for IRSSI and X-Chat.

The client is merely responsible for interpreting this data and displaying it. In this way, porting the system to a variety of IRC clients is very simple, since
the client script will be short, and effectively contain no code specific to the game being played.

In other words, the Java part is smart. The script is dumb and is just there to make things look pretty.

This idea works. Currently, client scripts have been designed for RSSI and XChat. Since both these programs use Perl for scripting, the scripts are practically identical, with a few client specific modifications.

Porting this script to other IRC clients shouldnt be too much of a hassle, since its just the frontend thats ported, not the chess game itself. Anyone wanting to create frontend scripts for other IRC clients, please feel free to do so.
