Not very much software is Centos-specific, but anything that runs on Red Hat Enterprise versions should work on the corresponding Centos version, including the things in third party 'EL' rpm repositories and commercial products (like Matlab...). The biggest searchable, up to date collection of open source software project descriptions is probably http://freshmeat.net, but once you locate an interesting project you might want to see if you can find an RPM-packaged version at EPEL, rpmforge, etc. for easy installation and updates instead of trying to build from source yourself. And you might like 'R' as an alternative to octave or matlab. -- Les Mikesell lesmikesell at gmail.com
