the title gives short version; long of have c++ api wrapped c & exposed perl via xs. has worked fine number of years, have run use-case suspect may caused duplicate load of common library. the symptom have in-house perl wrapper around tibrv. and, we've wrapper around c++ api internally uses tibrv. when perl script uses both of these apis, second hangs on creating tib transport. individually, both work perl. i suspect, have nothing up, somehow has shared state , perl, default loading libraries rtld_local set, may causing issue (this pure hunch). have nothing with, know tib aware of surroundings, think possibility. my question: possible use dlopen flags, such rtld_global perl's xsloader ? i.e. can 1 change dlopen flags when native lib opened without rebuilding perl/xs? everything i've seen online far seems indicate need use dynaloader, require rebuild our lib (because of means in export our c++ symbols) in manner suitable use dynaloader (which not). i

what efficent way query dynamodb objects ? such objects have ten properties , want distinct count based on 3 properties . in case need counters it's better use atomiccounters ( http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/workingwithdditems.html ). in case, dynamodb doesn't support out of box keys composed out of 3 attributes, unless concatenate them, option create redundant table key concatenation of 3 attributes , each manage objects, update atomiccounter (add, delete, update - not needed actually). then query counter, avoiding scans. so, it's space complexity gain speed of retrieving data.

i'm writing mechanism (in ios app) detect whether device jailbroken checking app sandbox's integrity doing fork(); . know if attempting call violate app store guidelines? you can't create new process in ios application on non jailbroken device (you error such "operation not permitted"), can create new thread using pthread library. edit : if you're trying detect whether device jailbroken, don't think violate store guidelines 'try' fork, it's more legal question technical question. i found nothing in app store guidelines forbid use of calling low-level api. logical, since jailbreak doesn't exist, forbid you're not able ? the closest things found : apps read or write data outside designated container area rejected apps download code in way or form rejected apps install or launch other executable code rejected

after applying new style @ runtime mainform of application creates new window handle – there way stop or reassign handle getting tonne of following error: 'system error. code: 1400. invalid window handle' is there way manipulate process forces new handle assigned? i solved doing following: my main form created unseen 'helper' form never displayed, have visual components - throwing handle error when trying redraw these visual components, replaced relevant components objects instead (note did not write code originally). there no way avoid re-creating window handles. instead, override window's createwnd , destroywnd methods you're notified when window re-created. also, avoid keeping persistent references handles of windows might destroyed. instead, read handle property each time need it. won't have watch notifications. beware of reading handle different thread, though, since may cause window become associated wrong thread. wrap code

how filter 2 tables in c#? table 1 contains full data , table 2 contains content of table one? what want (it's not clear question)? take table1, filter , pass result table2? then: dataview dv = table1.asdataview(); dv.rowfilter = fexpression; // example "myid = 3" datatable table2 = dv.totable(); // if want typed datatable, can (although there other ways): mytypeddatatable table2 = new mytypeddatatable(); datatable temptable = dv.totable(); table2.merge(temptable);
