Pragmatism in the History of GNU, Linux and Free/Open Source Software 8

If you ask a lot of people why Linus Torvalds and the Linux kernel that he wrote became one of the most prominent open source projects of all time, while Richard Stallman's GNU project has received much less attention beyond hacker circles, they'll tell you the difference has to do with Stallman's excessive commitment to an uncompromising ideology. Is that really accurate?

Open Source History: Why Didn't BSD Beat Out GNU and Linux? 9

So why has BSD been consigned to the margins of the open source ecosystem, while GNU/Linux distributions rose to fantastic prominence? Read on for some historical perspective.

On Its 25th Birthday, We Want to Hear About Your First Time with Linux 2

Linux turned twenty-five years old this month. Do you remember where you were when Linus Torvalds first announced his open source operating system kernel to the world in August 1991?

Maybe you were already hacking on Minix and hoping, like Torvalds, for something that suited your needs better. Perhaps you were waiting with bated breath for the release of GNU's kernel, the Hurd, and disappointed by its perennial delays. Or you were running Net/2 BSD but wishing for a Unix clone tailored to your Intel 386 computer, as Linux was.

Open Source History: Why Did Linux Succeed? 81

One of the most puzzling questions about the history of free and open source is this: Why did Linux succeed so spectacularly, whereas similar attempts to build a free or open source, Unix-like operating system kernel met with considerably less success?

Work Today: What DevOps and the On-Demand Economy Have in Common
