i've been trying streamline of code, condensing , making calls easier can. 1 of things i've been trying fuse 2 common overloads have on place one. follows: void myclass::addsomething(something & a) { vectorofsomething.push_back(&a) } void myclass::addsomething(std::vector<something*> a) { (unsigned int = 0; < a.size(); i++) vectorofsomething.push_back(a[i]); } the class abstract. vectorofsomething vector of pointers somethings. essentially, instead of having this: std::vector mysomethings = {&something1, &something2}; addsomething(mysomethings); i want this: addsomething({something1, something2}); so more similar first overload (no need user create vector of pointers first). looking around 2 ways saw either through: std::initializer_list or variadic templates, both of not afraid admit foreign me. i've given shot initializer lists have run ton of errors trying various things. i've managed function accept list, can...

problem given (x, y) positions of every word in flight e-ticket, extract flight numbers , corresponding destination/arrival times + dates. my first try use regex flight numbers, dates, , times. match flights correct dates & times using (x, y) positions. done set of rules came with. issue these rules becoming longer , more complicated try make work variety of e-tickets. for example, "a320" "aegean airlines (a3) flight 20" or irrelevant "airbus a320". another example: "320p" time, 3:20pm, or part of irrelevant code appears in e-ticket. how approach it? topics should into? handwritten rules ok such things, need better tools simple regular expressions. try out gate framework , jape rule engine, regexes, operates so-called annotations (e.g. "token", "word", "noun", "number", sentence, etc.). here's gate manual give both - quick introduction , in depth feature description. p...

i have code: cookie::forget('vendor'); return redirect::route('vendor_login'); what supposed do, remove vendor cookie , redirect login page. however, doesn't delete cookie. understanding, expect send setcookie header vendor value of null , negative time. doesn't send setcookie header @ all. why this? this works perfectly: cookie::queue('paddle_vendor', null, -1); return redirect::route('vendor_login'); you can use queue method this: cookie::queue(cookie::forget('vendor')); return redirect::route('vendor_login'); which in way allows delete multiple cookies @ once too. more information checkout answer here: https://stackoverflow.com/a/33724308/247670 or antonio said: $cookie = cookie::forget('vendor'); return redirect::route('vendor_login')->withcookie($cookie);

i'm using go-worker process resque jobs. job has payload has nested json structure this: [{ "key-a":"val-a", "key-b":"val-b", "files":[{ "key-a": [ {"a":"b","c": "d"}, {"e":"f","g": "h"} ], "key-b": [ {"a":"b","c": "d"}, {"e":"f","g": "h"} ] }] }] now go-worker gives me args ...interface{} represents json payload, not actual json text. there idiomatic way convert that( args ) correct types (could use package this.) using type assertions manually seems bit tedious such thing. if it's giving actual go objects (i.e. bunch of map[string]interface{} , not json string itself) there isn't can besides bunch of type assertions. you re-marshall json parse again correct structs, that's...

in ruby, better (style?) specify method takes &block or not? the choice merely seems matter of style long method body contains yield . for example, given: def abc1(a, c) puts yield puts c end def abc2(a, c, &block) puts yield puts c end the following 2 calls: abc1('a', 'c') { puts 'b' } abc2('a', 'c') { puts 'b' } each print , return same things: a b c => nil so, if it's matter of style, what's convention (or better style)? with current code first 1 better. while using yield then, no need use &block , implicit . yes, 1 thing remind, have pass block while using yield , if not there error. although error can handled using block_given? . ruby's yield statement gives control user specified block method's body. so, if using again &block redundant, don't need use it.
