在eMule, Preferences.cpp中，强制最小上传速度限制与下载速度限制成正比的方法:

uint16 CPreferences::GetMaxDownload(){
//dont be a Lam3r :)
    uint16 maxup=(GetMaxUpload()==UNLIMITED)?GetMaxGraphUploadRate():GetMaxUpload();
    if( maxup < 4 )
        return (( (maxup < 10) && (maxup*3 < prefs->maxdownload) )? maxup*3 : prefs->maxdownload);
    return (( (maxup < 10) && (maxup*4 < prefs->maxdownload) )? maxup*4 : prefs->maxdownload);
}

#define FUCK_VS6_CANT_COMPILE_TEMPLATES_WITHOUT_HANDHOLDING ((float*)0)

... 

SetPinsFromChannels`<float`>(&pinbuf, streambuf, &inmapper, FUCK_VS6_CANT_COMPILE_TEMPLATES_WITHOUT_HANDHOLDING);

我经常发现这个

// fix it!

我在一个充满显式怪异类型转换的函数中见过这段代码:

// Since today's CPUs are really fast, this is dedicated to those who said:
// " You can't use Moore's Law as an excuse to write bad software. "

代码太可怕了:)
