    The Open Source community is about shared effort for shared gain, not personal recognition.

    Have you spent a moment in the "Open Source community"? The majority of contributions to Linux are from profit-making corporations.

    Not true for the Linux Kernel. Most of the contributions to Linux come from individuals without a company. After that are unknown contributers. Then companies.

    I guess MMA is Mixed Martial Arts, I've never heard of that term or acronym before.

    Humans have been into aggression for since before the dawn of the earliest civilizations, do you really think it's going to go away any time soon? Maybe you need to brush up on your history a little bit, "civilized" societies can and do go from their pinnacle to their worst in short time spans, shockingly short if there is a lot of pent-up tension. In some ways, I think it might be argued that civilized societies pretend they are free of humanity's worst aspects, when it's just denial or turning a blind eye.

    Yeah? Link?

    Maybe that coincided with the time when there were no free 3D drivers, and Red Hat forwarded the "Fuck You" from hardware vendors since they (a) hadn't the drivers developed yet and (b) had a principle problem with including proprietary drivers.

    Then (in my opinion) Ubuntu et al not-so-strict distros included proprietory drivers, Linux became more present on the desktop, Hardware vendors noticed Linux. Open-source driver developers had more time and resources to continue and eventually brought forth free drivers.

    What's your version?

  6. Re:Half the story on First GNOME Census Results · · Score: 4, Insightful

    To claim that Canonical is freeloading on other companies' contributions is a bit of myopic, in my opinion. How many upstream bug reports came from Ubuntu users?

    Too many, we marked them as dup. But your point is invalid since Canonical != Ubuntu users and Canonical != Ubuntu maintainers. Latter are all in the volunteer camp. Red Hat users & maintainers are probably largely there too.

    The way I see it Ubuntu is mainly a packager (distribution) and behaves like one. They mainly configure, build and distribute the existing software. Of course they provide patches for bugs they encounter, and they send it upstream to reduce their own work.

    But Canonical doesn't have the means and will to truly commit developer resources to Linux (like Red Hat does). They want to achieve something with what is there*, and they are very good at communicating, community-building, reacting to users, connecting users and developers. That is Ubuntu's value.
    Red Hat has some of this too, but for them it is business to engineer a Linux that works, because that is what they sell.

    *Greg Kroah Hartman complained Ubuntu doesn't give patches upstream.

    If you look at the maintainance map, you can see that Redhat is relavant in several areas, but most of it is volunteer. Canonical is not so relevant here (except for the default theme and the calculator -- lol).

    Imagine your company was structured like that. Or that you'd have to sell this plan to your stakeholders. :) But it works!

    Throwing advertising magazines into the trash is not a method of opting out.

    This is about telling the publisher that you are not interested in such material. Disabling/deleting {images, cookies, history} is not the same thing.

    TFS suggests signaling the publisher and requiring the publisher to react based on it.

    One technical method of implementing this would be an additional HTTP-Request Header, like Accept-Language, or to reuse the now-abandoned Charge-To field.

    By not only explaining how something should be done but also expressing the reasoning to why this method has been chosen

    Yes - a truly excellent thing to do. They should do the same thing with laws - define the law as they currently do but also provide a justification for the law. That way the law can be challenged in the future when the justification no longer holds. In addition, no one will ever misinterpret the meaning of a law and use it for purposes for which it was not designed.

    That is what already happens in some European countries. It is part of being a judge to interpret laws while taking the intention of the lawmaker into account. Laws have accompaning documents that detail these (and you can tell from history/press from that time).

    Now back to format specifications - code makes for a very poor specification. While code can implement a specification, it generally does so in an unorganized fashion. Specifications should be clear - having no ambiguities or vagueness. Code is not so clear. And as the parent mentioned, generally does not communicate reasoning to the reader.

    Mathematically based definitions are great - they are both clear and organized. Tools such as lex/flex/yacc/bison combine code with mathematical definitions to implement such specifications. The ideal format specification would include a mathematical definition along with reasoning explaining the design decisions.

    In design theory there is the notion of explicit and implicit knowledge. Unless you are very reflective and a very experienced designer, you will not be able to make all your knowledge and your whole decision process explicit.

    There is also a theorem in logic preventing you from writing the perfect universally understood specification.

    The issue is burning down large areas of rain forest to get more short-term farmland, which uses up oxygen as well as permanently destroys the source for oxygen. The newspaper is not so relevant, since it is partially recycled and partially grown for the purpose.
