KeyPoint

copyright&&copyleft

Open source and copyrights
Anything that is not public domain has a copyright, the copyright does not have to be explicit. That is, the authors of a work hold copyright even if there is no copyright notice.

在人们认为有价值的诸多价值之中，自由是最有价值的一种价值。

What qualifies as open source

根据许可的目的，我们可以区别许可证赋予你的各种不同权利。复制和再发布的权利，使用的权利，为个人目的修改的权利，发布修改后的作品的权利。一个许可证可能会对这些权利加上一些限制或给出一些附加条件。

无限制的拷贝权
无限制的使用权
无限制的针对个人使用目的而修改的权利

For licensing purposes, we can distinguish several different kinds of rights that a license may convey. Rights to copy and redistribute, rights to use, rights to modify for personal use, and rights to redistribute modified copies. A license may restrict or attach conditions to any of these rights.

The Open Source Initiative is the result of a great deal of thought about what makes software open source or (in older terminology)free. Its constraints on licensing require that:

An unlimited right to copy be granted.

An unlimited right to use be granted.

An unlimited right to modify for personal use be granted.

　　“自由软件”　实际上指的是一种自由，而不是价格。

　　“自由软件”　中的自由是指用户运行、拷贝、研究、改进软件的自由。

　　“自由软件”　使用“copyleft”来合法地保护每个人的自由。

CopyRight 版权

Copyright is a legal concept,giving the creator of an original work exclusive rights to it, usually for a limited time.Generally, it is “the right to copy”, but also gives the copyright holder the right to be credited for the work, to determine who may adapt the work to other forms, who may perform the work, who may financially benefit from it, and other related rights.

Copyright was invented after the advent of the printing press and with wider public literacy. its origins in Britain were from a reaction to printers at the beginning of the 18th century.

YOU CAN NOT :publish without authorized,publish if after modifying,copy

public domain 公有领域

Works in the public domain are those whose intellectual property rights have expired

Public domain works can serve as the foundation for new creative works and can be quoted extensively. They can also be copied and distributed to classes or digitized and placed on course Web pages without permission or paying royalties.

copyleft 反版权

Copyleft: Pragmatic(务实的) Idealism

Every decision a person makes stems from the person’s values and goals. People can have many different goals and values; fame, profit, love, survival, fun, and freedom, are just some of the goals that a good person might have. When the goal is a matter of principle, we call that idealism.If you want to accomplish something in the world, idealism is not enough—you need to choose a method that works to achieve the goal. In other words, you need to be “pragmatic.”

一个程序遵循 Copyleft，我们首先声明它是有版权的；然后，我们给它加上发布的规则，这个规则就是一个法律声明，它赋与所有人有使用、修改和重新发布程序的代码及其衍生作品的权力，但要求在这个过程中这个发布规则是不可以改变的。这样的话，代码和自由权力在法律上就不可分割了。

商业软件开发人员通过版权剥夺了用户的自由，我们使用版权来给予他它自由。这就是为什么我们把“版权(Copyright)”改称为“Copyleft”。

GPL

隶属copyleft.应该说是copyleft最初的模式之一.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software—to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation’s software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.

MIT

隶属non-copyleft.(copyleft坚持认为在自由软件基础上作修改后的软件，仍旧是自由软件。Non-copyleft许可则不坚持这一点。 proprietary[prə’praiətəri])
最宽松的一种开源协议之一.有权利使用、复制、修改、合并、出版发行、散布、再授权及贩售软件及软件的副本。被授权人可根据程序的需要修改许可协议为适当的内容。而需要履行的义务仅仅是在软件和软件的所有副本中都必须包含版权声明和许可声明

BSD

隶属non-copyleft.
可以自由使用这些代码，包括修改、再分发.使用并修改、再发布BSD授权的源代码时，新的代码需要附带BSD协议

Apache协议

这些权利可以应用于拷贝权，也可以用于专利权(scope of work)。

story of android

“Google has taken the Linux kernel, and nothing else from a “traditional” Linux system.
Google只用了kernel，别的东西都没用。”

“Android also solves the problem that the phone manufacturers had been having for many years: a free version of Java and a unified application layer that programmers can write to that will work on all phone platforms that integrate it.

它解决了长期令手机制造商头痛不已的问题：业界缺乏一个开源的Java虚拟机，以及统一的应用程序接口。现在，程序员只要写一次程序，就能在各种手机硬件平台之上使用。”

Kernel和Android的许可证不一样，前者是GPL许可证，后者是Apache许可证.Google有意选择了这样做，并且特意修改Kernel，使得原本应该包括在kernel中的某些功能，都被转移到了userspace之中，因此得以避开开源.Google也放弃了构建一个真正开源的手机系统的机会.这就是Android干的事情：它修改了Kernel，但是又不提供修改的细节，自己搞了一个封闭的系统。说得难听一点，它利用了开源社区，要求开源社区为它做贡献，却又不愿提供回报

Hall of Shame

This is a list of projects, persons or companies violating Libav’s license. The list is part of an effort to raise awareness of license violations and get violators to comply with the licensing terms in order to eventually move them from this Hall of Shame to our Hall of Fame instead.
