唐纳德·克努斯的另一个经典作品:

注意上面代码中的bug; 我只是证明了它是正确的，并没有尝试过。

    // At this point, I'd like to take a moment to speak to you about the Adobe PSD format.
    // PSD is not a good format. PSD is not even a bad format. Calling it such would be an
    // insult to other bad formats, such as PCX or JPEG. No, PSD is an abysmal format. Having
    // worked on this code for several weeks now, my hate for PSD has grown to a raging fire
    // that burns with the fierce passion of a million suns.
    // If there are two different ways of doing something, PSD will do both, in different
    // places. It will then make up three more ways no sane human would think of, and do those
    // too. PSD makes inconsistency an art form. Why, for instance, did it suddenly decide
    // that *these* particular chunks should be aligned to four bytes, and that this alignement
    // should *not* be included in the size? Other chunks in other places are either unaligned,
    // or aligned with the alignment included in the size. Here, though, it is not included.
    // Either one of these three behaviours would be fine. A sane format would pick one. PSD,
    // of course, uses all three, and more.
    // Trying to get data out of a PSD file is like trying to find something in the attic of
    // your eccentric old uncle who died in a freak freshwater shark attack on his 58th
    // birthday. That last detail may not be important for the purposes of the simile, but
    // at this point I am spending a lot of time imagining amusing fates for the people
    // responsible for this Rube Goldberg of a file format.
    // Earlier, I tried to get a hold of the latest specs for the PSD file format. To do this,
    // I had to apply to them for permission to apply to them to have them consider sending
    // me this sacred tome. This would have involved faxing them a copy of some document or
    // other, probably signed in blood. I can only imagine that they make this process so
    // difficult because they are intensely ashamed of having created this abomination. I
    // was naturally not gullible enough to go through with this procedure, but if I had done
    // so, I would have printed out every single page of the spec, and set them all on fire.
    // Were it within my power, I would gather every single copy of those specs, and launch
    // them on a spaceship directly into the sun.
    //
    // PSD is not my favourite file format.

var arbitraryNumber = 10;
//I don't know why. Just move on.

在一个艺术资产导出工具中，我偶然发现了一个从数字(阿拉伯)到罗马数字的完整转换器。它是这样的:

/*
//You can tell I was bored
//I wanted to do this for a long time
char* ConvertToRoman(int number, int base)
{
... whole code here
}
*/

编写这段代码的人的团队已经处理了很长时间，我猜这影响了他们的理智。

#如你所见:我注释了代码!
