I have installed Instiki on Abu. Instiki is a wiki server intended for simple wikis. The server itself is written entirely in Ruby and is extremely extensible. In its lingo, a server hosts a list of “webs”, each corresponding to the wiki of a project. To see the current list of webs hosted by Abu, use this URL:
http://abu.aladdin.cs.cmu.edu/
So far we have two sandboxes for playing and two actual webs. There is a web unofficially used by the FOCS 2005 local arrangements (I guess we really just use it as a notepad online). There is also a web called Papers Illustrated, which is Dan Golovin’s brain child if you recall the Town Meeting we had in the beginning of the semester. PI is password protected for the moment, but most CMUers know the password anyway. I imagine that when PI gets more content, we will publish the web so that Google can crawl it.
I have also patched Instiki a bit to add ASCIIMathML to it. Now you have another way to play with ASCIIMathML by going into the Sandbox.
Finally, since we have the server software set up already, if you want to have your own simple wiki hosted on Abu, let me know. Instiki is not as industrial-strength as MediaWiki, but it is probably adequate for most small projects.
Cheers!
