Hardware Compatibility Ratings
Frederic Lepied announced the hardware4linux.info website on the Linux Kernel mailing list, "the site is collecting hardware compatibilities and incompatibilities with Linux distributions in a collaborative way: users run a hardware collector program, upload the resulting file and then rate and comment how their hardware works."
The project's website goes on to explain, "components are rated according to their Linux compatibility. You'll see on the site some numbers like 4.5 x 2 for rated components. This means that the mean note for the component is 4.5 and that 2 persons have noted this component." The rating scale goes from -5 "does not work" up to 5 "works out of the box".
