is there way initialize unsigned field in bitfield 0xfff...(according its' size ofcourse) ? if use -1 warning assigning signed unsigned variable. one solution manually create init values in enum , use them: enum init_bit { // etc i_3 = 7u, // use longer names because global space i_4 = 15u, i_5 = 31u, // etc }; you write once , becomes easy: x x = {/*other fields*/, i_4, /*other fields*/}; another solution found init 0 , decrement. defined because dealing unsigned type. if need initialize can create function this: x get_x() { x x; x.a = 0; --x.a; return x; } with optimizations enable compiler direct initialize: get_x: movl $15, %eax ret you can use function initialization: x x = get_x(); of course has disadvantage need init other fields of x in get_x . where x defined as: struct x { unsigned : 4; }; typedef struct x x; it seems tricky initialize bit fields without warnings (gcc 6.1): x x = {-...

i need in disabling , enabling item selectmanycheckbox component in jsf page. first of all, selectmanycheckbox component showing 3 chechboxes (loan - health - transfer). list populated bean has code: private list<hrcertificate> hrcertificateslist = new arraylist<hrcertificate>(); //getter , setter private string loanflag=""; @postconstruct public void init() { this.hrcertificateslist.add(new hrcertificate(("loan"), "lc")); this.hrcertificateslist.add(new hrcertificate(("health"), "hi")); this.hrcertificateslist.add(new hrcertificate(("trasnfer"), "te")); } in same bean, running sql statement return either yes or no , value adding loanflag variable.so if flag="y", need enable loan checkbox user can select else need disable selectmanycheckbox . issue facing difficulties in applying logic disable , enable item selectmanycheckbox where in above code listing , enabling ...

i have application written in c++ , testing system (also in c++). testing system pretty complicated , hard change (i want make small changes). class looks this: class derived : public base { public: void somefunc(const anotherclass& file) { } }; there several functions inside. testing system creates derived class instance , uses it's methods stuff. now want able write solution in python. need two-way integration. idea write python function, executed every time when somefunc called. , don't want lose variables' values in python 1 launch of function another. , want able use methods defined in base class instance python. how can achieve these things? i chose boost.python these purposes. now, understand, how use c++ function, or simple class in python after work. don't understand how launch python function c++. the second question - boost.python choice? need fast and, @ same time, easy use. thank help. i recommend using cython sort of thing...

i'm triggering r script via scheduler. r script causes errors (maybe due input problmens). after each run, r-out file history log. log super helpful in checking if went planed unfortunately gets overwritten every day. question is: how can different r-out file each day (e.g. date it) best regards , thank you, phil to generate filename includes current date, take output of sys.date() , use paste0 to compose name of file including date. maybe this: filename <- paste0("r-out_", sys.date(), ".log") #> filename #[1] "r-out_2016-08-24.log" the format of date can changed format() if desired (thanks @konrad reminding this). instance, use format(sys.date(), "%d-%m-%y") obtain day-month-year form typically used, e.g., in europe: filename <- paste0("r-out_", format(sys.date(), "%d-%m-%y"), ".log") we can use sink() to redirect console (standard) output of script file. in case script edi...
