i've been reviewing draft version of c++11 standard. section on lambdas , , confused reasoning not introducing polymorphic lambdas. for example, amongst 100001 ways polymorphic lambdas used, had hoped use code such following: template<typename container> void foo(container c) { for_each(c.begin(), c.end(), [](t& t) { ++t; }); } what reasons: was committee ran out of time? that polymorphic lambdas hard implement? or perhaps seen not being needed ptb ? note: please remember example above not one, , provided guide types of code. answers solely concentrate on providing workaround above piece of code not considered valid! related sources: lambda expressions , closures c++ (document number n1968=06-0038) can lambda functions templated? the reason don't have polymorphic lambdas explained pretty in this posting . it has concepts feature pulled c++11: essentially, polymorphic lambdas ordinary, unconstrained function templates , didn...

what's difference of using loop instead of while(true) while using receive actors. loop seems work faster, why, , what's going on under bonnet? is there bad use loop instead of while(true)? more context. i'm doing performance tests within simple ping/pong code. , i'm using receive. this ping class: class receiveping( count : int, pong : actor ) extends actor {def act() { var pingsleft = count - 1 pong ! start pong ! receiveping while(true) { receive { case receivepong => if (pingsleft % 10000 == 0) console.println("receiveping: pong") if (pingsleft > 0) { pong ! receiveping pingsleft -= 1 } else { console.println("receiveping: stop") pong ! stop exit() } } }}} instead of while(true) performs better loop. thanks using loop releases thread other tasks, while while doesn't. so, if using many actors, use of loop mak...

how can modify/rotate axis angle world coords object coords? see below: void rotatematrix4(float *m, float angle, float *axis); //this function rotates matrix in object space void rotatelocal(float angle, float *axis) { rotatematrix4(m, angle, axis) } void rotateglobal(float angle, float *axis) { //do axis here rotatematrix4(m, angle, axis) } you found answer - multiplication between tranformation matrix , vector - transforming axis vector object coords. look @ transformation matrix more information on transformation matrices. (i comment on answer - rank not yet high enough...)

is there syntax allows use struct initialization syntax: struct { int a; int b; } int main() { a = { 1, 2 }; //syntax return 0; } in initialization list? e.g. class b { public: b(int a_, int b_) : obj { a_, b_ } { } private: obj; }; if have class public member variables, can automatically use same way structs. in c++ there's not way define arbitrary initializer list behavior. in c++0x there is, pointed out here . if happen using gcc, feature supported in gcc 4.4 , above (if compile parameter -std=c++0x)

as software developer, offer free trial versions of software download. can see stats many download trials don't run them. main target user pc novices, think many of them doesn't realize have run downloaded installer. question: would possible write small download client in flash, starts when user clicks download button, automatically downloads .exe file , runs when downloaded? no, that's not possible, , dangerous security flaw. should make instructions clearer, somewhere around download button, users realize it.
