What is “open-source software licensed under the MIT license” I wanted to use laraspace as my laravel boilerplate. It says in the license area "Laraspace is now an open-sourced software licensed under the MIT license." Does this mean I can use this however I wanted?
No It means you can use it in accordance with the terms of the MIT license.
Yes you can. What you do is called mere aggregation. Your app and the GPL container run isolated and do not share memory space: they are clearly separate programs vs parts of one program, so your app does not get infected by GPL.
You should probably get a lawyer, but my reading is this: The company whose SDK you use owns their SDK, owns their code, and is free to take any of your ideas how to improve their code without paying you. But they say that ideas are ten a penny, so this is mostly there to prevent pointless lawsuits. On the other hand, it says that everything you do with your product is yours. I might be completely wrong, that's why you should get a lawyer.
As the copyright holder you are free to license your work however you want. The fact that you have licensed your work under a CC license to one group does not prevent you from licensing it to someone else under a different license with different terms. This is true even if the CC license could apply to this other person. The CC license doesn't restrict what you can do with your own work. It only restricts what other people can do when they choose to use your work under the terms of the CC license.
This is going to depend on several things. First of all, do you have a lawful, licensed copy of the SDK? My understanding is that Nintendo only licensed the SDK to selected game companies. If what you have is an unauthorized copy, you do not have the legal right even to use it. If what you have is properly licensed, then you do. Or is what you have an unofficial SDK created by someone other than Nintendo? Secondly, what does the license agreement that comes with the SDK provide? Does it require developers to register with Nintendo? If it does, you will need to comply. Nintendo cannot prevent others from writing programs designed to run on their hardware. But they can control who uses their development software, if they choose to. You cannot reproduce in your game any of Nintendo's copyrighted software (or anyone else's) without permission. That applies even more strongly if you intend to sell the software. But you can use any development software for which you have a valid license in whatever ways its license permits. I would expect this includes creating games. It would include selling games that you create that do not use any of Nintendo's code, unless there is a specific provision forbidding that in the license agreement.
They have copyright in their additional text, and possibly in things like their visual design choices (fonts, layout etc). They may also have introduced a few deliberate typos to detect any literal copies from their version (rather as mapmakers add a few imaginary features to their maps). None of this creates any rights to the original text. You are still free to produce your own copies of the original text. Just get it from some other source so you can be sure not to include anything of theirs.
You give SE 2 licences The CC-BY-SA one and the one that goes “the perpetual and irrevocable right and license to access, use, process, copy, distribute, export, display and to commercially exploit such Subscriber Content … as reasonably necessary to, for example (without limitation):”. SE can choose which one it uses. Even though the enumerated cases are “without limitation”, they indicate the general area where the 2nd licence would be “reasonably necessary”. If SE used it outside that domain and did not comply with CC-BY-SA they would arguably be in copyright violation.
The web site appears to be interacting with a copy of the MIT-licensed code, which I will call &quot;M&quot;. Neither the site nor the code that displays the site is a copy, but if a copy of M is on Bob's server, it might be considered to be a part of the code that supports or &quot;powers&quot; the site. In general, calling a separate program does not make that program part of the calling program. Bob must make sure that the local copy of M contains the required copyright notice and &quot;as-is&quot; notice. As Bob is &quot;using&quot; and not &quot;distributing&quot; M, that ends his obligations. It would be good practice and courteous of Bob to include on his web page where M can be invoked &quot;Powered in part by M, written by {M-author}&quot; or some similar notice, but the MIT license does not impose any such requirement. A license could impose such a requirement, but MIT does not.
