The Myth of the Isolated Kernel Hacker 282

Ant writes "The Linux Foundation's report (PDF) on who writes Linux — "... Linux isn't written by lonely nerds hiding out in their parents' basements.

          There are a variety of kernel issues (think wireless drivers and other hardware support) that have a major impact on the userland experience.

          And there's plenty drivers living in userland missing. For example anything connected by USB, the kernel can do raw read/write to all USB devices but without a driver to know where and what to write that won't do any good. A linux issue yes, but not a kernel issue.

          On the other hand, what Canonical are focussing on, and what makes Ubuntu popular, is the user experience. They are doing all the tidying up of the installer and package handling so that the non-techie user doesn't get baffling (to them) messages about mismatched packages etc. In some ways, you should see them more as a packager than a developer. In which case it is hardly surprising that they contribute little to kernel development. The kernel, by and large, is the bit that you don't package.

        Also from TFA, there's another list of companies that do sign-off patches. Google is at 10.5% on that list, behind only Red Hat, above Novell, Intel, and IBM.

        They're a little bit further down.

        The next two rows on the list in TFA are as follows:

        17: Freescale 1,375 0.9%
        18: Google 1,261 0.9%

        I'm not sure why the parent decided to stop where they did.

        These rankings are based on number of kernel changes submitted broken down by employer.

        However it seems that Google employees are making a significant contribution to Linux project management and quality processes though: Red Hat employees sign off on over 36.4% of changes, which is the highest proportion of sign-offs in the hands of a single company, but Google has second place in that table with 10.5% of all sign-offs. It looks like several Google employees are filling the roles of subsystem maintainers - they may not write as much code as some other companies but they are still contributing some senior people.

      Seems a lot of people don't know squat about Canonical. Some rich guy invested a good bit of his fortune into making Linux widely known and acceptable on the laptop. So far, he's done a pretty good job. If he contributes nothing else back into the upstream system, he attracts some pretty bright people to the Linux community - SOME of whom go on to contribute something. Reality check: Ubuntu does contribute, whether they actually work on the kernel or not.

    • Considering the mess that is userland and the desktop, you should be thankful they even exist. I mean, shaving off .0000002 ms off kernel loading time is great too, but perhaps someone should be focused on the desktop experience and maintaining a good distro without too much worrying about the kernel.

    • In that case, where are GNU and Debian?

      I'd imagine that they make up a considerable portion of the 18% of contributions made by individual developers. Given that Ubuntu is a variant of Debian with a radically overhauled user interface, one would imagine that any Ubuntu kernel hackers would be encouraged to contribute upstream to Debian, rather than to Ubuntu itself.

    I hope this finally kills off the "GPL is bad for business" myth. Every one of those companies is paying for work on the kernel because it is good for their business.

      Yes, once Linux was established as a viable OS, companies jumped on the bandwagon.

      The real business issue about GPL'd code isn't whether established companies will support it once it is successful, but whether you can start your own for-profit software business if you license your software under the GPL.

        whether you can start your own for-profit software business if you license your software under the GPL.

        Depends on what the alternatives are and what your business model is. Assuming we narrow down the choices to the two best known open source licences (others are broadly similar to one of the other) and proprietary licensing:

        • Want to do all the development yourself, distribution yourself, not using GPL licensed libraries, want to make your money from license sales? Proprietary.
        • Want to accept community contributions and sell a proprietary version, happy for competitors to use your code, do not need GPL libraries, want others to redistribute? BSD or GPL and persuade contributors to sign over the copyrights, or cleanly separate open and proprietary components and LGPL.
        • Do not want to sell a proprietary version, want to use GPL licensed libraries, want to accept outside contributions, want to prevent people from reselling your code without contributing back, want other to distribute? GPL
        • Doing all the development yourself, but want to use GPL libraries, want others to redistribute, want to prevent competitors reselling your code without contributing? GPL
        • Want to re-assure users that the software will still be around if you go bust? GPL or BSD. Additionally want to stop competitors reselling a proprietary version? GPL.

        Obviously this does not cover anything like all the possibilities, but I just want to make the point that there are business reasons for every choice.

    For the longest time, it seems like major business have collaborated in one of several ways:

    • Standards-setting bodies, often backed by industry cosortia
    • Contractually established relationships.

    But with Linux, it seems like a new model of collaboration for companies. It's mostly a meritocracy where a company's stature cannot get a bad or only-self-serving idea pushed into the end result. But because of that discipline, the final product is so compelling that companies want/need to participate anyway.

    It pays for companies using Linux to contribute to the development. The long term savings of using Linux massively outweighs the small contribution of programming resources. And those contributing to development get to address the technical issues on top of their priority list. You can't get that kind of service out of Microsoft.

    We're quickly approaching the time when an operating system is more like a utility than a product. A commodity delivery mechanism for business services. The potential for Linux, very quickly approaching realization, is that it can provide a unified stack from a mainframe down to embedded systems. That type of efficiency is very powerful economically. I'm sure MSFT can swim against that tide a long time but, eventually, efficiency will win.

    The Linux kernel ought to be done by now, and stable.

    Drivers, file systems, and networks ought not to be in the kernel. That's a big part of the problem.

    Real microkernels like QNX don't change much. USB and FireWire support were added without kernel mods, for example.

    Yes, microkernels require extra copying. But copying is cheap on modern CPUs, as long as what's being copied was accessed recently and is in cache. Fear of copying cost dates from older CPU architectures, where instruction cycles mattered more than cache footprint.
