The Linux Foundation Releases Annual Linux Development Report

“Who Writes Linux” report surfaces new data on how fast the OS is being built, who is writing the code, and what companies are sponsoring the work 

NEW ORLEANS – LINUXCON & CLOUDOPEN – September 16, 2013 – The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, today announced the immediate release of its 2013 report “Linux Kernel Development: How Fast It is Going, Who is Doing It, What They Are Doing and Who is Sponsoring It.”

This is the fifth such report that is released on a roughly annual basis to help illustrate the Linux kernel development process and the work that defines the largest collaborative project in the history of computing. This year’s paper covers work completed through Linux kernel 3.10, with an emphasis on releases 3.3 to 3.10. The last report was released April 2012 and focused on 2.6.36 to 3.2.

Key findings from this year’s paper include:

  • Nearly 10,000 developers from more than 1,000 companies have contributed to the Linux kernel since tracking began in 2005. Just since the last report, more than 1,100 developers from 225 companies have contributed to the kernel. In fact, more developers and companies are contributing to Linux than ever before with Linux kernel 3.10 seeing the most developer contributions ever.
  • Mobile and embedded companies are increasing their investments in Linux. Linaro, Samsung and Texas Instruments together increased their aggregate contributions from 4.4 percent during the previous version of the paper to 11 percent of all changes this year. Google’s contributions are also up significantly this year.
  • The Top 10 organizations sponsoring Linux kernel development since the last report include Red Hat, Intel, Texas Instruments, Linaro, SUSE, IBM, Samsung, Google, Vision Engraving Systems Consultants and Wolfson Microelectronics.Afterappearing on the list for the first time in 2012, Microsoft notably dropped off the list entirely this year. A complete list of the top 30 organizations sponsoring this work is included in the paper.
  • The rate of Linux development is unmatched. The average number of changes accepted into the kernel per hour is 7.14, which translates to 171 changes every day and more than 1,200 per week.

The report is co-authored by Jon Corbet, Linux kernel developer and editor of LWN.net; Greg Kroah-Hartman, Linux kernel maintainer and Linux Foundation fellow; and Amanda McPherson, vice president of marketing and developer services at The Linux Foundation.

“Linux represents the future of how new software and technologies will be built. Understanding how it’s developed is important to the industry,” said Jim Zemlin, executive director at The Linux Foundation. “This year’s Linux development report represents exponential growth in the community and its pace of development, illustrating how collaboration advances innovation. We are inspired by the work of these thousands of developers and companies that sponsor that work and know they are fueling the future of the technology industry.”

The paper is being released today at LinuxCon and CloudOpen North America. LinuxCon, which has sold out every year since its debut, is the world’s leading conference addressing all matters Linux for the global business and technical communities. CloudOpen focuses on the open cloud and those projects that comprise it – Ceph, CloudStack, Chef, Gluster, KVM, OpenStack, Puppet, SaltStack, Xen Project and more – all in one place.
