this code illustrating question. #include <functional> struct mycallback { void fire() { } }; int main() { mycallback cb; std::function<void(void)> func = std::bind(&mycallback::fire, &cb); } experiments valgrind shows line assigning func dynamically allocates 24 bytes gcc 7.1.1 on linux. in real code, have few handfuls of different structs void(void) member function gets stored in ~10 million std::function<void(void)> . is there way can avoid memory being dynamically allocated when doing std::function<void(void)> func = std::bind(&mycallback::fire, &cb); ? (or otherwise assigning these member function std::function ) unfortunately, allocators std::function has been dropped in c++17. now accepted solution avoid dynamic allocations inside std::function use lambdas instead of std::bind . work, @ least in gcc - has enough static space store lambda in case, not enough space store binder object. std::fun...

it confusing me when matter of creating react application. there plenty of examples available on internet. out of them using .js file while using .jsx file. i read .jsx file , says lets write html tags. same thing can written in .js file also. then actual difference between these 2 extensions .js , .jsx ? there none when comes file extensions. bundler/transpiler/whatever takes care of resolving type of file contents there is. there other considerations when deciding put .js or .jsx file type. since jsx isn't standard javascript 1 argue not "plain" javascript should go own extensions ie., .jsx jsx , .ts typescript example. there's good discussion here available read

i have method manage exception handling below. question that, in case typeof exception our point, approach recommended? using catch (system.exception ex) when(ex.gettype() ==typeof(exconeexception)){...} or catch (exconeexception ex) {...} public t mymethod<t>(func<t> codetoexecute) { try { return codetoexecute.invoke(); } catch (system.exception ex) when(ex.gettype() ==typeof(exconeexception) ) { throw new exconeexception(ex.message,ex); } catch (system.exception ex) { throw new exctwoexception(ex.message, ex); } } update: solution has 3 projects, ui, services , dataaccess. each part has own custom exception-handler class. imagine that, code in question in service project. codes should call method execution. if there run-time error type of exconeexception, means error in service section, else, there should error in data access part; so, exctwo...

i using pycuda cuda programming. need use random number inside kernel function. curand library doesn't work inside (pycuda). since, there lot of work done in gpu, generating random number inside cpu , transferring them gpu won't work, rather dissolve motive of using gpu. supplementary questions: is there way allocate memory on gpu using 1 block , 1 thread. i using more 1 kernel. need use multiple sourcemodule blocks? despite assert in question, pycuda has pretty comprehensive support curand. gpuarray module has direct interface fill device memory using host side api (noting random generators run on gpu in case). it possible use device side api curand in pycuda kernel code. in use case trickiest part allocating memory thread generator states. there 3 choices -- statically in code, dynamically using host memory side allocation, , dynamically using device side memory allocation. following (very lightly tested) example illustrates latter, seeing asked in ques...

i having trouble authorization policies. have basewebapicontroller action [httpdelete("{id}"), authorize(policy = "administrator")] public virtual async task<iactionresult> delete(int id) {} but in controller inherits above want give access users also, policy like: [httpdelete("{id}"), authorize(policy = "all")] public override task<iactionresult> delete(int id){} it seems regular users cannot access action. have search further errors in policy configuration, or since controller inherited,m it's attributes neglected? thanks the authorizeattribute attribute inherited , allows applied multiple times. that means when inheriting method has authorizeattribute , carried over. final function definition in subclass this: [authorize(policy = "administrator")] [authorize(policy = "all")] public override task<iactionresult> delete(int id) so route has 2 policies in place. kind of proble...
