How Open Source Took Over the World

GOING WAY BACK, pretty much all software was effectively open source. That's because it was the preserve of a small number of scientists and engineers who shared and adapted each other's code (or punch cards) to suit their particular area of research. Later, when computing left the lab for the...

Linux Kernel 4.12: "One of The Bigger Releases"

Linus Torvalds released Linux kernel 4.12 on Sunday, July 2 and remarked how it was "one of the bigger releases historically." Indeed, just shy of 12,000 commits, only 4.9 was significantly larger, and that was because Greg Kroah-Hartman declared it an LTS release. Despite Torvalds' unassuming...
