Linux的评论

这里有很多不错的……

这些都是linux中的注释

我的最爱:

./arch/sparc/kernel/ptrace.c
/* Fuck me gently with a chainsaw... */

./drivers/scsi/qlogicpti.h
/* Am I fucking pedantic or what? */

在js代码中:

// hack for ie browser (assuming that ie is a browser)

这是众所周知的，但我喜欢它(在sys/ufs/ufs_vnops.c中):

/*
 * A virgin directory (no blushing please).
 */

在FreeBSD内核源代码树中(甚至在之前，回到4.xBSD)
