Mac and Linux versions of the Tor anonymity browser just received a temporary fix for a critical vulnerability that leaks users' IP addresses when they visit certain types of addresses.

With complex projects like OpenStack, it can be intimidating to jump straight in. Besides the scope of the project itself, there are lots of systems and processes to familiarize yourself with. It can be hard to know where to get started.

Although Linux has yet to breach 5 percent of that market, it continues to claw its way up. And with the help of very modern, highly efficient, user-friendly environments, like PinguyOS, it could make even more headway.
