Linux Kernel Developers on 25 Years of Linux

One of the key accomplishments of Linux over the past 25 years has been the “professionalization” of open source. What started as a small passion project for creator Linus Torvalds in 1991, now runs most of modern society -- creating billions of dollars in economic value and bringing companies from diverse industries across the world to work on the technology together. Hundreds of companies employ thousands of developers to contribute code to the Linux kernel. It’s a common codebase that they have built diverse products and businesses on and that they therefore have a vested interest in maintaining and improving over the long term. The legacy of Linux, in other words, is a whole new way of doing business that’s based on collaboration, said Jim Zemlin, Executive Director of The Linux Foundation said this week in his keynote at LinuxCon in Toronto.

Car manufacturers cooperate to build the car of the future

Automotive Grade Linux (AGL) is a project of the Linux Foundation dedicated to creating open source software solutions for the automobile industry. It also leverages the ten billion dollar investment in the Linux kernel. The work of the AGL project enables software developers to keep pace with the demands of customers and manufacturers in this rapidly changing space, while encouraging collaboration. Walt Miner is the community manager for Automotive Grade Linux, and he spoke at LinuxCon in Toronto recently on how Automotive Grade Linux is changing the way automotive manufacturers develop software. He worked for Motorola Automotive, Continental Automotive, and Montevista Automotive program, and saw lots of original equipment manufacturers (OEMs) like Ford, Honda, Jaguar Land Rover, Mazda, Mitsubishi, Nissan, Subaru and Toyota in action over the years.

Torvalds at LinuxCon: The Highlights and the Lowlights

On Wednesday, when Linus Torvalds was interviewed as the opening keynote of the day at LinuxCon 2016, Linux was a day short of its 25th birthday. Interviewer Dirk Hohndel of VMware pointed out that in the famous announcement of the operating system posted by Torvalds 25 years earlier, he had said that the OS “wasn’t portable,” yet today it supports more hardware architectures than any other operating system. Torvalds also wrote, “it probably never will support anything other than AT-harddisks.” Read more
