Tails is a live media Linux distro designed to boot into a highly secure desktop environment. Tor is a browser that prevents somebody watching your internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Learn why anonymity matters and how you can protect yourself with this Linux Journal Weekend Reading. Tor Hidden Services 

Kernel development is truly impossible to keep track of. The main mailing list alone is vast beyond belief. Then there are all the side lists and IRC channels, not to mention all the corporate mailing lists dedicated to kernel development that never see the light of day. In some ways, kernel development has become fundamentally mysterious.

Daylight Linux is the only official distribution for the Raspberry Pi to work with the Fluxbox interface. With Fluxbox, Daylight Linux is one of the lightest and fastest distributions for all Raspberry Pi models. Many programs, games and system tools were developed during a long year of work in Python 3 to create version 3.

Matthew Wilcox recently realized there might be a value in depending on C extensions provided by the Plan 9 variant of the C programming language. All it would require is using the -fplan9-extensions command-line argument when compiling the kernel. As Matthew pointed out, Plan 9 extensions have been supported in GCC as of version 4.6, which is the minimum version supported by the kernel. So theoretically, there would be no conflict.

Mathematics and science tools often depend on cluster and high performance computing, both undeniably Linux strengths. Couple that with the maturity of the science tools available for Linux and you get a lot of computational bang for your buck. Join us this weekend as we review physics, chemistry, biology, astronomy, and other science programs for Linux. Open Science Means Open Source--Or, at Least, It Should Why open source was actually invented in 1665.

In this article, I introduce another option available for the astronomers out there—specifically, Cartes du Ciel, also known as SkyChart. Similar to other larger astronomy programs, you can use SkyChart from the desktop to the observatory.
