Sometimes you are working on Windows and want to watch an original DVD movie ... and ??! RealPlayer ask for additional software like Windows Player. What Windows Player 9, 11 ... or what? ... What disaster?! ... I want to watch my movie ... hear Mozart. How to do?

There are a new program, that is free and called 'vlc' that runs on Windows, Linux the MacOS capable to support any video format: from QuickTime to DVD movies, to MPG to MP4, etc.


It is simple and effective and is free software.

Suppose you want to investigate the DNA code ... Well also this is possible using Emboss and KDE, as well Kaptain a simple KDE program. Check this excellent article: http://userpage.fu-berlin.de/~sgmd/

... Suppose you want to solve the Galois Groups from

Look the difference between a not-soluble-in-radical (X^4+X^2+5=0, X^5-X^2-1=0) and X^5+X+1=0.

 ... All this is free Software. Internet connections are everyday faster. Computer Hardware is everyday cheaper and faster. Software is more and more simple to be used by everyone and ...  sometimes is free. So, we expect great things for the incoming future.
