你可以解释说，POSIX 是一种用于文件访问的标准编程接口，Unix 发行版都广泛采用，因此在你维护多个 Linux 版本的情况下，可以减少锁定。有了这个斜坡，高管们就可以推论说，因为他们已经在单一的 Linux 发行版上实现了标准化，所以 POSIX 合规性并不会增加多少价值。对于像 Hadoop 这样包括文件系统在内的垂直集成系统来说，它也没有什么意义。
通过寥寥数语建立起一个斜坡，你成功地让那些技术水平不高的人参与到决策过程中来。这个斜坡可能不会把听众带入 POSIX 版本和 Linux 版本的深渊，但它提供了一个在拟议决策范围内进行推理的心理模型。
陡峭的坡道适合快速攀登，但如果你想带领受众登上珠穆朗玛峰，坡道就会变得令人厌烦。因此，要考虑听众需要爬到多高（或多深）的地方才能对所介绍的内容进行推理。在定义术语时，要根据问题的上下文来定义，突出相关属性，省略无关细节。例如，关于 POSIX 历史和 Linux 标准库的细节与上述决策无关，应该省略。

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
