background update hash algorithm, Bloom update operation. I'm not in favor of introducing a new level, such as introducing a cache layer, because it increases maintenance and requires complexity management. The bell also needs to be bell people, since in order to avoid the same IP address pair of the same calculation results, then change the algorithm instead of introducing a new layer, at the same level, compensation is not necessary.All in all, Bloom filter hash algorithm must be kept delicat
For a variety of reasons, the company needs to bring the Java program into the war package. It was initially packaged with a ZIP command, which was available at first, but later unusable. Find a better way today.

Be prepared to take a moment to read the Java code in the Java.util.concurrent package, which I personally think can be roughly divided into five parts (if there is a mistake, I also want to correct it).
First part aomic data type
This section is placed in the Java.util.concurrent.atomic package, which implements the data type of the atomization operation, including Boolean, Integer, Long, and referrence

When we use BCB to do a program, the next step is to do the packaging program, released to the user. From the point of view of the packaging program, we have a lot of choices, in terms of BCB, each version of the BCB CD has a packaging program, for these packaging procedures, I have only used BCB5 and BCB6, the other version has not been used, do not dare to comment, but the BCB6 with the packaging program obvious problems, Support for Chinese is also not good, so the thought of whether can use
