Linus大婶在slashdot上回答一些编程爱好者的提问,其中一个人问他什么样的代码是他所喜好的,大婶表述了自己一些观点之后,举了一个指针的例子,解释了什么才是core low-level coding

下面是Linus的教学原文及翻译——

“At the opposite end of the spectrum, I actually wish more people understood the really core low-level kind of coding. Not big, complex stuff like the lockless name lookup, but simply good use of pointers-to-pointers etc. For example, I’ve seen too many people who delete a singly-linked list entry by keeping track of the “prev” entry, and then to delete the entry, doing something like。(在这段话的最后,我实际上希望更多的人了解什么是真正的核心底层代码。这并�
