Linux turns 27 today
Linux is 27 years old today. Happy birthday Linux and thank you Linus Torvalds for giving us a real operating system to use on our computers. I have used Linux for over 20 years and I cannot imagine using anything else on my computers.
I have never used Windows as a primary operating system on any of my many computers. I started with DOS, then went to OS/2, and then to Linux. To be completely honest I do have one VM with Windows on it that I use for research for articles and books. But I keep it tightly caged in that VM. ;-)
