Linux does everything that many users want it to, but some people have tasks that require Windows applications. You can dual-boot both operating systems, or run Windows in a virtualized environment on Linux. Alas, virtualization makes the guest OS almost useless for processor- and RAM-intensive tasks like editing videos and playing games. Now, a Ubuntu-based distro called andLinux takes cooperation with Windows to a whole new level.
The miracle ingredient in andLinux is its coLinux kernel. The coLinux project takes a stable release of the Linux kernel and ports it to run on Windows. That means that, unlike virtualization software, andLinux installs on Windows like any other application.
But there's more to andLinux than just sticking the coLinux kernel in a stock Ubuntu. According to Joachim Gehweiler, one of the developers of andLinux, the project also had to roll in the Xming X server and PulseAudio sound server and make sure these components work together.
