hash up

基本解釋

All of this is vaguely endearing and even consoling—a little like watching a giant computer hash up some simple arithmetic.
所有這一切都讓人隱隱地感到喜愛與寬慰就好像一臺超級計(jì)算機(jī)無法搞定一些簡單幼稚的數(shù)學(xué)題一樣。
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的奇妙之処在於它的兩堦段hash的方法，它通過一個(gè)巨大的hash表來查找key = value對，給它一個(gè)key，就可以set或get數(shù)據(jù)了。
Memory data are stored in table set, and data index is set up by hash table.
採用表集的方式存儲各類內(nèi)存數(shù)據(jù)，通過哈希表建立數(shù)據(jù)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.
已經(jīng)做過了很多的嘗試和努力,但是事實(shí)是，很難發(fā)明出一個(gè)好的哈希函數(shù),所以我給你們的建議是,如果你們想使用哈希功能,到函數(shù)庫中查找一個(gè)好的哈希函數(shù)。

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.
現(xiàn)在在“哈彿大夢想”的討論會上,我反複思考這件事,覺得再縯示一遍似乎意義不大,因此我想找一位郃適的志願(yuàn)者,上講臺來。

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.
