Who really writes “Linux”? A special report from the Linux Foundation

Steven posted a good eWeek article summarizing the recent Linux Foundation report on who writes and contributes to the Linux kernel development. Too many have written blogs with titles like “who writes Linux” that I had to put “Linux” in quotes in my title. The reason is that this document/report is about the Linux kernel and there are many things that people commonly associate with “Linux” that are outside the kernel. Think of Gnome which is written by the Gnome community, KDE which is sponsored by Trolltech, package management tools from Red Hat, Debian or Novell (e.g. YaST, Apt Yum), a multitude of libraries,  and even OpenOffice which is still controlled by Sun, but now with contributions from IBM.

So I would agree this report is fantastic - it provides a view into what’s going on beyond what we “think” happens. The Linux kernel community is a great success story in what Amanda calls “mass community collaboration” - even more ironic because there are many competitors, vendors, academics, hobbyists, customers and other random experts collaborating in one place.

Read the report (it’s “free as in beer”) and find out everything you wanted to know about Linux kernel development (including perhaps that IBM is the #3 contributor to the kernel). The story this report tells is a truly unique feature of the Linux community. You won’t see it anywhere in the communities or practices of other OSs, no matter how “open” they proclaim to have become.

The report is interesting in how it also debunks some myths that somehow get spread around. For instance, some have said “kernel development will slow down as the features catch up to UNIX/Windows”. Not true.

Some have said “Linux is just IBM” or “Linux is just Red Hat” trying to position Linux as dominated or caused by one entity that they’re not fond of. Again, not true (see the section of the report on Contributors).

Finally, take a look at how some end user companies are participating and reaping the benefits of a true collaborative development community. Did you know your next VW will be powered by Linux? Did you ever think the same features that make an auto’s systems “crash-proof” could also help on a server or mobile phone? The VW bullet is a pure example of innovation being applied to adjacent spaces - it would never happen in Windows, AIX or Solaris.

Companies like Sony, Nokia, and Samsung ship Linux as a component of products like video cameras, television sets, and mobile telephones. Working with the development process helps these companies ensure that Linux will continue to be a solid base for their products in the future.

Companies which are not in the information technology business can still find working with Linux beneficial. The 2.6.25 kernel will include an implementation of the PF_CAN network protocol which was contributed by Volkswagen. PF_CAN allows for reliable communications between components in an interference-prone environment – such as that found in an automobile. Linux gave Volkswagen a platform upon which it could build its networking code; the company then found it worthwhile to contribute the code back so that it could be maintained with the rest of the kernel. http://lwn.net/Articles/253425/ for more information on this work.

So with that I will end my praises and simply point you to the source over at the LF website here.
