你遇到过的源代码中最好的注释是什么?

Re eating one's own dogfood: We have the same term in our workplace (granted, only because I introduced it). My code is peppered with comments that say "TODO" and indicate something that ought to be done eventually, but a comment saying "DOGFOOD" (both keywords are always at the beginning of the comment, in all caps) means something that must be done before this program can be used even internally. It's a handy thing to search for, as the word "dogfood" is never going to appear in a quoted string - if it does, I can always just say "dog-food" or something - so even a case-insensitive search will come up with the right results.

Regarding zeroing the accumulator: I've done exactly the same thing when programming an Intel 80x86 (I started on the 8086 and moved up from there into the modern Pentiums). XORing a register with itself is the quickest and tightest way to clear it. Using "MOV AX,0" requires three bytes (opcode and two bytes of literal 16-bit zero), whereas "XOR AX,AX" is only two; it's even more noticeable with the 386-and-higher extended registers, where "MOV EAX,0" requires five bytes (four bytes of 32-bit zero). My C/C++ compiler always zeroes registers this way, so I'd assume it's still the best way (although I haven't studied opcode timing tables in ages, and probably both XOR reg,reg and MOV reg,imm take one clock).

我最喜欢的(我必须承认我用过很多次):

// Yes...I know this is repulsive and stupid.
// But <%CompanyOwnerOrManagerToken%>, not knowing a thing about code,
// demanded I do it anyways. SO, go crap on their desk, not mine.
// K THX BYE 

不是在代码中,而是在相关的bug跟踪系统中:

这不可能是我代码中的bug。我非常小心地编码。

为什么你不应该将你的软件开发外包的一个经典案例:

public class Contact
{
    //...    

    /// <summary>
    /// Gets or sets the name of the first.
    /// </summary>
    /// <value>The name of the first.</value>
    public string FirstName
    {
        get { return _firstName; }
        set { _firstName = value; }
    }
}

这是我最喜欢的评论。

/// I intend to do this as shittily as possible because there are many better products that will totally blow this out of the water
/// and we don't have them so whatever

在后面的文件中,我们有更多的乐趣

/// sidestep a bug in WCF (that we can't send types across)
/// or, depending on how you look at, this issue is a Feature
