svg - Raphael - Transform after Serialization -

-

i using raphael draw paths. each path has associated rectangle [container] size , position of bounding box. using container dragging both shapes.

in move callback, update both positions both move together.

this works great until serialize. serializing path, creating container on fly after deserialization.

immediately after converting json , back, things fine. can print out current transform of path , looks correct. doing transform on path after results in path being reset , moved 0,0.

here fiddle shows problem.

if move rect, can see both objects move together.

if click 'save/load', things fine, , path prints same.

if drag, path gets reset 0,0. printing shows transform has been reset 0,0.

i trying find out how make path move did before serialization. getting lost in process? or there internal state needs updated?

raphael.json serialises data stored in elements. not preserve temporary data stored in paper object indeed lost in process when calling r.clear(). example drag events bound elements not preserved.

however main issue here drag function, notice how dragging square second time applies transformation top left of paper. suggest using raphael.freetransform (which included in fiddle) handle this.

i wrote both raphael.json , raphael.freetransform plugins , have struggled same issues. i'm working on application lets save save , restore state of paper (similar you're doing) , works fine. if need feel free open issue on github.

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...
