1.Penguin Landscape

On the year of Linux's 30th anniversary, Linux security expert and TechRepublic writer Jack Wallen ponders how the open-source OS has profoundly affected the landscape of enterprise businesses.

Linux is 30 years old. I was just starting graduate school by the time Linus Torvalds began working on the project. I remember so well, back at Purdue, the first time I used email. I felt like I'd entered a magical realm where anything was possible. It was all text-based (probably Elm or Mutt) and once you knew the keyboard commands you were ready to communicate with everyone.

Little did I know, at the same time I was learning the ins and outs of email, somewhere across the globe another student was learning how to build an entire operating system.
