From Novell’s own Greg Kroah-Hartman, a presentation on Linux Kernel Development [pdf], subtitled “How, What, How Fast, and Who.” It’s full of juicy information, including this breakdown of contributors:
- Unknown Individuals 33.2%
- Red Hat 11.8%
- Novell 9.7%
- Linux Foundation 8.1%
- IBM 7.9%
- Intel 4.3%
- “Amateurs” 3.9%
- SGI 2.2%
- MIPS 1.5%
- HP 1.3%
Of course, this raises as many questions as it answers; who are these unknown indviduals who contribute fully a third of the changes to the Linux kernel?
