In this site you will find articles and links on various subjects; mostly Linux, Open Source and Programming related, but not exclusively. If you have any suggestions for articles or require expansion of any points in the articles, please feel free to contact me at this email address and I'll try to accommodate you.

In this article I try to explain some of this without too much complexity.
