对于我编写的memcache包装器/处理程序接口模式类,我实现了以下方法。
/**
* Do not use, ever - left in place for testing purposes
*/
function I_David_WillHuntYouDownAndHurtYou_Badly_IfIFindThisUsedAnyWhereInTheAppLibrary(){
...
}
这基本上是一个超级核函数,它告诉所有单独的memcache服务完全刷新自己,并从我用于键的单个名称空间计数器(例如{_counter_key value}_)重新开始。{_counter_key value})
Another minor novella I wrote was for an automated downloader for a data vendor, detailing how much I hated this vendor and went to great lengths of postulating that their infrastructure's batch system was run by a gerbil, running on a wheel and after so many revolutions of the wheel the next queued task would be started. It was written over the course of 6 months of adding additional exception handling, estoric checks like ( if we got 768 Bytes of \s characters, that means the query to their DB timed out and the spaces are the result of empty failure print statements.

从《雷神之锤III》的资料中,我在一些随机的帖子中偶然发现了这一点。该文件的完整源代码可以在这里找到。这是一种非常快速的求平方根倒数的方法。至于最好的评论呢?当然,这是一种常见的方法,但考虑到它附着在直线上,它的神奇之处在于它的伟大之处。
float Q_rsqrt( float number )
{
long i;
float x2, y;
const float threehalfs = 1.5F;
x2 = number * 0.5F;
y = number;
i = * ( long * ) &y; // evil floating point bit level hacking
i = 0x5f3759df - ( i >> 1 ); // what the fuck?
y = * ( float * ) &i;
y = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration
// y = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed
#ifndef Q3_VM
#ifdef __linux__
assert( !isnan(y) ); // bk010122 - FPE?
#endif
#endif
return y;
}
这个我在Python 2.5的“twisted”包中找到的(文件是tcp.py在第371行)
# Limit length of buffer to try to send, because some OSes are too
# stupid to do so themselves (ahem windows)
return self.socket.send(buffer(data, 0, self.SEND_LIMIT))
