It seems true that Microsoft loves Linux! Not really?

Microsoft is a true business machine. They are always looking for business, that's not a bad thing any way :)

What's Linux? And why it matters?

Linux is an OS (operating system) similar to the Microsoft Windows or Mac OS X. Because Linux is open source & free, it is rising gradually i.e see Android or Chromebooks etc.

The IT War Story

The story begins with GNU (GNU's Not Unix!) by Richard Stallman and then Linux by Linux Torvalds. They are combined called GNU/Linux, the free OS mentioned above.

Microsoft is mainly closed source software company, their own choice, no offence. They are basically competitors, hence IT war between them. But the scenario is changing now a days. Microsoft has open sourced some its softwares i.e Visual Studio etc. Visit GitHub repositories of Microsoft for details

Moral of the story

These signs are good for the Linux & the open source world. By the way, Linux is also available in the stores :P
Linux in the stores :p
