1. Free as in beer VS Free as in speech
Free as in beer VS Free as in speech是用来区分免费软件和开源软件的。
2. Free as in beer
Free as in beer是指免费软件。免费软件(Freeware)是指不需以金钱购买使用授权的电脑软件,但使用上会有一种以上的限制,例如禁止反组译软件以研究软件写法、禁止修改软件源码、禁止再次散布出去给其他人使用等。例如Oracle的JDK,可以免费用,但不能获取源码,不能修改源码。Free as in beer说白了就是只能免费用,其它的就不要想太多了。
3. Free as in speech
Free as in speech是指开源软件。开源软件(英语:open source software,英文缩写:OSS,中文也称:开放源代码软件)是一种源代码可以任意获取的计算机软件,这种软件的版权持有人在软件协议的规定之下保留一部分权利并允许用户学习、修改、增进提高这款软件的质量。开源软件就不必多说了。
