hash up

基本解释

All of this is vaguely endearing and even consoling—a little like watching a giant computer hash up some simple arithmetic.
所有这一切都让人隐隐地感到喜爱与宽慰就好像一台超级计算机无法搞定一些简单幼稚的数学题一样。
It behaves as though it were a giant hash table, looking up key = value pairs. Give it a key, and set or get some arbitrary data.
Memcached的奇妙之处在于它的两阶段hash的方法，它通过一个巨大的hash表来查找key = value对，给它一个key，就可以set或get数据了。
Memory data are stored in table set, and data index is set up by hash table.
采用表集的方式存储各类内存数据，通过哈希表建立数据索引。

There's been a lot of work done on these over the years, but in fact, it's pretty hard to invent a good hash function. So my advice to you is, if you want to use something was a hash, go to a library. Look up a good hash function.
已经做过了很多的尝试和努力,但是事实是，很难发明出一个好的哈希函数,所以我给你们的建议是,如果你们想使用哈希功能,到函数库中查找一个好的哈希函数。

Now at Harvard Thinks Big I happened to tear into this thing myself and it would seem a little pointless to re-hash that same demo so instead I thought I'd solicit an ideally sufficiently strong volunteer to come on up.
现在在“哈佛大梦想”的讨论会上,我反复思考这件事,觉得再演示一遍似乎意义不大,因此我想找一位合适的志愿者,上讲台来。

So, Team Obama has pulled another Christmas Day bomber hash-up.
CENTERFORSECURITYPOLICY: From Russia, with love
Much more important is the fact that Mr. Obama is in the process of losing the two wars he inherited, and making a hash-up of the one he initiated in Libya.
