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>
Today I tried the released Linux version of World of Goo. I tried the demo and after I got through the demo chapter I decided that I will buy this game.
See the World of Goo web page for more information.
The four reasons why I loved to buy this game is first of all it provides a Linux version, second it has no DRM, third it is a small development team and not part of one of the big publishers and the forth and maybe the most important point it is so much FUN to play.
I’m off playing.
Im Roadhouse stehen Bier und Dart auf dem Nachtprogramm.
Kaum dort angekommen und die ersten Pitcher bestellt, haben wir uns gedacht wir spielen ein Cricket zu Acht. Hat natürlicherweise knapp eine Stunde gedauert und wir durften wieder sehen was passiert, wenn Spieler 3 die Tausender Marke überschreitet. Der Dartkasten ist aber nicht doof, der zeigt zwar den Punktestand auf dem 3-stelligen Display nicht korrekt ab, aber rechnen kann er.
