GPL for Books?

teebo writes "I'm am currently creating a large tutorial for Perl to take the place of many books in print on this subject. My goal is to have it be one of "the best" books there is on Perl. To achieve that goal, once it is written it will need constant updating and revision by The Community, perhaps even employing a cvs system. I would like to use some sort of license on it like GPL, but of course I cannot use that as it is for programs. What advice could you friendly smart cool people give me?" A similar question was asked with regards to databases and I mentioned the possibility of an Open Content License. Would such a thing help this issue as well?

      You can (superfluously) disclaim warrantee in a public domain release, too. If someone edits that out, it doesn't make you responsible for it.

      Also, it is pretty generally accepted that by using something in the public domain you accept full responsibility for the consequences of your own action.

      Thank you! I've been wanting to lay the groundwork for a project of mine, revolving around the studio I'm building (the one in which I keep saying I'll record OSS-writing mp3-releasing hacker musicians for free, which I will)

      My problem is this: I have a VERY LARGE amount of technical innovation concentrated in the equipment of this studio. Some of it is as simple as circuit tweaks for the equipment (such as a set of modifications for my vintage Small Stone phase shifter, or the rebuilt mixer and soon-to-be-rebuilt analog daughter card of the LX20 ADAT), and some of it is considerably more elaborate, most of all the monitor speakers which involve processes that are outright patentable. In addition there's a vinyl record turntable design which my scientist father (who holds several patents himself, in infrared sensor instrumentation) feels is also patentable.

      I want to make all this available to OSS hardware hackers and audio geeks, but I don't want anyone to rip it all off my website and publish a book, basically. I don't mind people working with the ideas, even companies selling stuff based on them, but I don't want restrictions placed on 'em or to be eclipsed by a more well-funded operation that can move quicker and publish on a large scale to people who've never heard of me.

      I'm very enthusiastic about RMS's proposed license! I'd like to know when he has a final version worked out, and if my needs can help shape this I'd like to become involved. Basically, where the soul of free software lies in the code, and the key concept is keeping it flowing freely, the soul of writing is in attribution- and the problem is not in making it flow, but in keeping reference to those who created it. It's not _hard_ to keep writing flowing freely, the hard part is doing anything other than hosing the original 'developer' of the writing. The problem is that you _want_ J. Random Whoever to be able to shop a version of the work to a publisher, and let them print up a copy- but you also want to be able to specify that the cover has to say "This is a version of Book X, which is freely available for download on the Web at (foo.bar.baz.com)" so people know they are not forced to spend money for that person's modification of your work. But they still get to make the published version, if they feel a strong market exists for such a paper printed volume! So can you- or you can just web-publish and if anyone wants a paper version in stores they can go to the trouble of doing so.

      With all the hysteria over intellectual property these days, I have to wonder whether the future will be very different- with such wide access to ideas and data, it seems that information will be valueless- and only WHAT YOU DO WITH IT will have value. If somebody can print up a wonderfully well organised and illustrated version of a pile of great but unkempt ideas I put on the web- THEY SHOULD. I still get to have the ideas, but if there's a market for a cleaned up polished 'rendition' of those ideas, why shouldn't someone get a chance at selling this additional effort they put in?

      Typically, there's one caveat- watch out for the corporations, any such proposal needs to at least understand the potential for aggregate entities like corporations to steamroller anything in their path. However, the inequity of this mustn't stop individuals from trying to interact socially in a world of ideas and exchange them freely- because frankly, you still lose if you become paranoid and do nothing and hide every bright notion you have. It is simply impossible to coexist or compete with corporations- so the idea is to somewhat ignore them in such a way that, although you're arguably giving them the ability to steamroller you, you're also cooperating with other individuals in a mutually beneficial way.

David Wiley got feedback from everyone interested and had the modification made in less than a day!

    The GPL is software specific, so I'm not sure what happens to hardware designs in GPLed projects.

    Is there a hardware specific GPL-like license for these designs? Both of these designs are somewhat commercially viable (OpenBIOS for embedded projects with low to mid production and OpenRemote for consumer applications).

    I would prefer it if my work could not be "embraced-and-extended." If a company modified a design, they would be obligated to release the details of the designs (schematics, microcode, etc).

    Like Woz, I wish schematics came with everything. There are schematics for my bass amp inside when it is opened. That's a good thing. Schematics are generally no longer available with computers (except many embedded computers).

    Sorry Havoc. Got carried away making links, not paying attention to what they pointed to. Argh. Great book in any case. :)

  27. Why? by Abigail-II · · Score: 2
    I've no idea why this project is being done. The current Perl documentation consists of about 1200+ pages of documentation. Except for the 10 files that make the "faq", all the documentation is released under the same conditions as Perl. That is, if you wish, under the GPL. So, the license cannot be a reason to start this project. Unless you want another license than either the GPL or the Artistic license.

    Or is it that you do not like the current documentation, and you think you can do better? But given that the current documentation is maintained by the same people developping perl, some of them authors of books like "Programming Perl" and "The Perl Cookbook", and including Larry Wall himself, and given the dubious quality of many Perl books, are you sure you are up to the task of creating something better?

    I agree the current documentation is far from perfect, but I think it's far more efficient to improve the current documentation than to write alternative documentation. As an added bonus, if you improve the current documentation, it'll be distributed with current and future versions of Perl, and kept up to date by the team maintaining Perl.
