Phase 1: Finally he's come to realize that there are some certain crucial elephants in the room in the U.S. and Canada.

Montage - 元曲《天净沙·秋思》

作者:马致远(元)


枯藤老树昏鸦,小桥流水人家。

古道西风瘦马,夕阳西下,断肠人在天涯。

What a montage.

J needs to revise his Linux installation doc.

I've been long muddled by the meanings of "hash", "hash function", "hash value", "message digest", and "hash table" in Compute Science.

Now finally I've made it clear to me that a hash function is simply a one-way encryption function which often is used to ensure a data file, or packet, transmitted over the internet has not been garbled.

Brouhaha. All that hodgepodge of different names and terms.

It's the same old hash of hash function over and over again, all in all.

By the way, a function is not a mapping.

"Data" is the plural form of the noun "datum" in the English language.
