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.
所有這一切都讓人隱隱地感到喜愛與寬慰就好像一台超級計算機無法搞定一些簡單幼稚的數學題一樣。
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，它通過一個巨大的hash表來查找key = value對，給它一個key，就可以set或get數據了。
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存數據，通過哈希表建立數據索引。

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.
已經做過了很多的嘗試和努力,但是事實是，很難發明出一個好的哈希函數,所以我給你們的建議是,如果你們想使用哈希功能,到函數庫中查找一個好的哈希函數。

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者,上講台來。

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.
