Linus Torvalds, the creator of Linux, is not only a maintainer and a programmer, he is also the public image of the kernel. He is a also a rather flamboyant character and, from time to time, he breaks the pattern and gives the Linux community something to talk about.
Linus Torvalds is not someone who just does his job and shuts up. He expresses his opinions on a number of issues, but the most interesting ones are about the kernel and the development process. He’s also very funny, but he can be mean (with good intentions) sometimes, which makes watching the kernel development process a very interesting activity.
