Does copyright apply to Stack Exchange answers and comments? So I asked a question on Worldbuilding Stack Exchange, and I got an answer that I really enjoyed. I loved the way the person described it. So I thought, is it okay to copy this and use it in other things? Short question: are Stack Exchange questions public domain?
Stack Exchange questions are not public domain, they are protected by copyright. Authors have granted a license under Subscriber Content, specifically content is perpetually and irrevocably licensed to Stack Overflow on a worldwide, royalty-free, non-exclusive basis pursuant to Creative Commons licensing terms (CC BY-SA 4.0) As long as you comply with the terms of the CC BY-SA 4.0 license, you may copy user content.
Yes Both melody and lyrics source back to the middle ages, as for instance described here. The difficulty could be to make sure you rely your derived work on a variant that is really in the public domain. E.g. if you use notes or lyrics from the Simon &amp; Garfunkel version and derive from there, you might violate their copyright.
You are in breach of Copyright. Plain and simple. Certain websites allow you to use the website content as long as a link is made, but the website must clearly state that. You may also use a tiny portion of the content if it falls under Fair Use, where "Fair Use" does not mean "I want to". The best thing to do is not to do it. You can't copy anybody's work without consent. If you're thinking about Google specifically then they offer multiple APIs so that you can use their content in a wide variety of ways.
All artistic and literary work has copyright at the moment of creation This includes things “built” in Minecraft. However, under the terms of the Minecraft licence you give a wide ranging copyright licence to Mojang: If you make any content available on or through our Game, you agree to give us permission to use, copy, modify, adapt, distribute, and publicly display that content. This permission is irrevocable, and you also agree to let us permit other people to use, copy, modify, adapt, distribute, and publicly display your content. You are not giving up your ownership rights in your content, you are just giving us and other users permission to use it.
I want to use a couple of lines from "What is life?" by Erwin Schrödinger as quote on the front of my thesis. Would i need permission for that form publisher or would that be convered in fair use? There are close cases of fair use, but this is not one of them. This is unequivocally and clearly fair use. It is a brief excerpt of a much larger body of work, it is for non-commercial use by a student, and it is for educational and academic purposes (presumably to advance science). Also do i need to attribute the quote properly Yes. This is necessary both because of the moral rights of the author under E.U. copyright law (assuming that works by Erwin Schrödinger are still in copyright), and for reasons of academic ethical considerations. It is still in copyright, because he died on January 4, 1961, which is 58 years ago. So, in countries that protect copyrights for the life of the author plus 50 years (the minimum required by the Berne Convention) this is out of copyright, but in countries that protect copyrights for the life of the author plus 70 years (e.g. Germany), the copyright is still in force until January 4, 2031. Also, even if the work were out of copyright, as a matter of academic integrity, you would be required to attribute the quote in an academic thesis in any case. Quoting someone without attribution in academic work is considered plagiarism, and could result in your thesis being stricken and also in your degree being revoked in a serious case. Government ministers in the E.U. have been forced to resign over plagiarism in their academic work as students in recent years. This is taken much more seriously in Europe than it is in the U.S.
You misunderstand the nature of copyright. Holding copyright allows you to decide how the work can be copied: there is no obligation on you to publish it if you don't want to. After your copyright expires you don't have to publish it either: the only thing that has changed is you can no longer prevent anyone making a copy. The lost works of Aristotle are in the public domain - if you can find them you can make as many copes as you like.
You probably can. There are a few questions here. First, is the message protected by copyright? In general, it probably is, but there are many exceptions that might allow you to use it without permission. Unfortunately, these exceptions vary from jurisdiction to jurisdiction. The exceptions tend to allow the use of small excerpts of a work for various sorts of purposes that don't undermine the copyright holder's ability to profit. That leads to the second question, which is why you are using that message. If you're including it in your source code so you can test whether a message generated at run time is in fact that message, that's one thing, and it's probably okay. On the other hand, if the owner of the copyright sells a database of all its message strings, and you're compiling a similar database that you also intend to sell, that's probably not okay. A third question concerns the Firefox license terms. It's entirely possible that they allow you explicitly to do what you're considering, in which case it doesn't matter what copyright law says about it. On the other hand, Firefox is open source software, and under some open source licenses, if you incorporate any of the source code in your own product, you are required to release your product's source code under the same license. If you're not already planning to do that, you should consider carefully whether including that error message would trigger that provision (if there is one) of Firefox's open source license.
If any elements of the game are protected by copyright, then you cannot reproduce those elements (17 U.S.C. §106) unless your reproduction falls under a fair use exception (17 U.S.C. §107). Elements that may be protected by copyright include: artwork specific language on each card the aggregate effects of the cards (i.e. copying a single card's effects might not infringe copyright, but if you copy the effect of a bunch of the cards, such that you are taking expression of the original author's creativity, that might infringe, even if you change the words used) Whether an element of the game is protected by copyright is a fact-intensive question that would depend on the specifics of the game. Whether your copy infringes is likewise a fact-intensive question that would depend on what you copy. Fair use is also a fact-intensive, case-by-case analysis, but in my opinion, it is likely that creating a computer program derivative work (17 U.S.C. §101) of the game for your own personal education would be considered fair use. From a practical standpoint, even if it were not fair use, it would be near impossible for the copyright owner to discover. Posting the code on GitHub tips the scales away from fair use because of (17 U.S.C. §107(4)): "the effect of the use upon the potential market for or value of the copyrighted work." But, none of the factors are determinative on their own. You ask: I likely cannot simply change all the names of the various cards to something else, right? I agree. In my opinion, the selection and arrangement of the effects attributed to each card is an expression of the author's creativity, and no matter what you call the cards, copyright in the game would be implicated if you retained the effects associated with each card. If I start changing the rules of the game, does that make it legal for me to share my source code, for instance? At some point, it will be an entirely different game, so certainly, in the limit, your work would not be infringing. We can't answer where that line is, but in general, the less of the original author's creativity that you re-use, the less likely a ruling of infringement. Also, in general, the more transformative your work is, the more likely a fair use exception would apply.
