MCL (Matti's Cool Linux) is an open source operating system based on the award winning and highly acclaimed Debian GNU/Linux distribution. It is actually based on snapshots of the testing branch of Debian, which are quite suitable for production machines.
Available for download as a dual-arch Live DVD
Users can download this Debian-based distribution from its official website (see link above) or via Softpedia as a dual-arch Live DVD ISO image of approximately 1.5GB in size, designed to support both 32-bit (i386) and 64-bit (x86_64) computers.
When booting the ISO image from the BIOS of a computer, using either a DVD disc or a USB flash drive, the user will be able to start the live environment with default boot options or in failsafe mode, perform a system memory diagnostic test, as well as to boot an existing operating system from the first disk drive.
Clean, simple and very fast graphical desktop environment
MCL sports a clean user interface, by using a desktop layout similar to the Windows 7 operating system, where the end-user can choose between different layouts. Moreover, the Cairo Dock has been replaced by an Xfce plugin that supports application pinning.
Includes both Xfce- and KDE-specific applications
It appears the developer decided to include both Xfce- and KDE-specific applications, among which we can mention the Thunar file manager, Krusader two-pane file manager, LibreOffice office suite, SMPlayer video player, VLC Media Player, Iceweasel web browser, Gwenview image viewer, Pinta image editor, Kompare diff viewer and KWrite advanced text editor.
In conclusion, MCL proves to be a cool and fast distribution of Linux that combines open source applications from various desktop environment with snapshots of Debian Testing. It is suitable for low-end machine or users who want a very fast Linux operating system.
