MICROSOFT --
Each year it's interesting to see how Microsoft's usage and contributions around Linux and open-source evolve. In a short period of time they go from sponsoring coffee at LinuxTag to enabling .NET and more on Linux to now in 2021 having made public their CBL-Mariner Linux distribution, supporting more features like eBPF and IO_uring on Windows, and continue heavily investing in the Windows Subsystem for Linux.

Each year it's interesting to see what new Microsoft plays there are around open-source and Linux. This year can be summed up by their many Mesa contributions, CBL-Mariner seeing monthly updates as their internal-focused Linux distribution, and more features at least inspired by Linux/OSS projects making their way from Windows. For running through many of the wild actions by Microsoft this year, below is a look at the most popular news stories on Phoronix pertaining to the Redmond company.
