Hello Together

We used a lot of proprietary CAS tools during our studies. There was Maple, Mathematica, Matlab and so on.
I just found out that there’s an open source CAS program. It’s called SAGE and you can get it on http://www.sagemath.org/download.html .

In Windows you would need VMware player, which is also free.

Give it a try

I recently came across a problem when trying to uninstall a package with pkgrm on OpenSolaris. The Error was something like:

… ## Removing installed package instance <SUNWatheros>
pkgrm: ERROR: CLASSES parameter undefined in…

You can solve this problem by using pkg (IPS) instead of pkgrm. The command would be:

pkg uninstall <packagename>
