mysql - best storage solution for data samples -

-

i'm developing system collect user activities samples (opened window, scrolls, enter page, leave page, etc.) , i'm looking best way store these samples , query it.

i prefer smart can execute sql-like group queries (for example give me window open events grouped date , hour), , of course flexible enough in case i'll need add columns in future.

i'm trying avoid thinking queries might need , save aggregated version of data time, since i'd drill-downs. (for example, count window open events date , time, , see event in each time-frame, or change unique userid).

thanks.

ps - use mysql task, data expected grow rapidly. i've experimented mongodb well.

i believe mongodb can solution. first of it's designed hold big data , it's easy use , scale (replica set or sharding). expression language solid. mean it's not powerful sql, still enough. here link mapping sql command mongodb.

there other alternatives, think or complex or expression language not powerful enough.

have @ link too, can find right solution you.

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...
