Caltech Sage Server
The caltech math department has a Sage server. Sage is intended to be a free, open source alternative to Mathematica, Matlab, Maple, etc. The home page for the project is here. One handy thing about Sage is that the notebook interface runs through a web browser, and there's no requirement that the web server serving the page and the browser viewing it be on the same computer. The Caltech math department bought a nice computer, and we've installed a Sage server on it, so you can use the equivalent of Mathematica, etc from your computer without installing anything!If you're associated with Caltech in some way, and you want to have access to this server, email me.
