easy calculation of weeks of certain period with java -

-

is there easy library or approach week (from date ~ date) of periods?

example: there 6 weeks(variable) (start 1 july, 2012 ~ 11 aug, 2012).

i want cut off 6 weeks 2 portions (variable). results be

1) 1 july,2012 ~ 21 july, 2012  2) 22 july,2012 ~ 11 aug, 2012... etc

with jodatime, can number of weeks between periods though.

all know start date , end date both variables , cutoffweeks amount(eg.6 weeks or 4 weeks).

final localdate start = new localdate(); final localdate end3 = start.plusweeks(3)

its not clear want, joda-time makes things rather easy.

i guess need :

public void dostruff(int cutoff){   int portion = cutoff/2;   final localdate start = new localdate();   final localdate end = start.plusweeks(portion) }

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
