i trying understand how std::ref works. #include <functional> #include <iostream> template <class c> void func(c c){ c += 1; } int main(){ int x{3}; std::cout << x << std::endl; func(x); std::cout << x << std::endl; func(std::ref(x)); std::cout << x << std::endl; } output : 3 3 4 in code above, think template parameter c third function call instantiated std::reference_wrapper<int> . while reading the reference , noticed there no += operator in std::reference_wrapper<int> . then, how c += 1; valid? how c += 1; valid? because reference_wrapper<int> implicitly convertible int& via conversion operator; , implicit conversions considered operands if there no suitable overload operand type itself.

i know there ttls on columns in cassandra. possible set ttl on row? setting ttl on each column doesn't solve problem can seen in following usecase: at point process wants delete complete row ttl (let's row "a" ttl 1 week). replacing existing columns same content ttl of 1 week. but there may process running concurrently on row "a" inserts new columns or replaces existing ones without ttl because process can't know row deleted (it runs concurrently!). after 1 week columns of row "a" deleted because of ttl except these newly inserted ones. , want them deleted. so there or there cassandra support use case or have implement on own? kind regards stefan there no way of setting ttl on row in cassandra currently. ttls designed deleting individual columns when lifetime known when written. you achieve want delaying process - instead of wanting insert ttl of 1 week, run week later , delete row. row deletes have following semantic...

what difference between ngswitch , nginclude? i need understand difference, can continue on project. does ngswitch hides dom elements? you may find v1.1.4 documentation more helpful (just ignore stuff animations if not using 1.1.4): ngswitch ngswitch conditionally adds/removes dom elements ( ng-show/hide alters css). nginclude can fetch partials/external html fragments. both create new child scopes prototypically inherit parent scopes. (a new child scope created each ng-switch-when/default .) you can use nginclude ngswitch : https://stackoverflow.com/a/12584774/215945 use nginclude when want (or can) reuse html fragments, such client ui ( https://stackoverflow.com/a/13005658/215945 ).

i have class a , < comparator. how can use them sort array of a in descending order? class { ... }; class lessa { bool operator()(const a& a1, const a& a2) const { ... } } vector<a> v; sort(v.begin(), v.end(), ???); i suppose should replace ??? based on lessa , can't figure out should go in there. thought of using lambda function, looking shorter. if want sort according relation defined lessa comparator, pass instance of lessa third argument (and, since using c++11, prefer global std::begin() , std::end() functions): std::sort(std::begin(a), std::end(a), lessa()); // ^^^^^^^ now if lessa() expresses < relation , want sort according opposite criterion, do: std::sort(std::begin(a), std::end(a), [] (a const& a1, const& a2)) { return lessa()(a2, a1); } another thing let custom comparator accept argument determines how should perform comparison: class compa { bool...

i'm migrating jquery app angularjs. what need do, change data array when scroll occurred, how can this? i have code jquery @ plunk: http://plnkr.co/edit/jdwxh5pmyecuwtsrutro?p=preview when scroll div, list visible elements index show. what want do, set directive or filter ( ng-check-visibility ) @ ng-repeat element, like: <div ng-repeat="item in data" ng-check-visibility> {{item.name}} </div> and directive change item setting value item.visible=true when element visible, otherwise, set false. can angular? ideas? here's way directive: var app = angular.module('myapp', []); app.controller('mainctrl', function($scope) { arr = []; for(var i=0; i<500; i++){ arr.push({id: i, name: 'name'+i}); } $scope.data = { items: arr, visible: [] }; }); app.directive('checkvisibility', function() { return { scope: { data: '=che...

i have developed java applet loads c++ dll through loadlibrary function. there, applet calls native methods implemented in c++ code. have created installshield installer puts c++ dll in required location on client computers. everything works fine on development pc, when try testing on "fresh" client computer not have jre installed, getting unsatisfiedlinkerror: can't find dependent libraries . don't know if there else need include. checked using dependencywalker , below saw. is there out of ordinary fresh windows install not include? else can determine dependency dll cannot find on client?

this general error visual studio 2012 has come recently. while debugging c++ application , after hitting break-point, clicking "go disassembly" produce following error dialog: disassembly cannot displayed source location. uncaught exception thrown method called through reflection. i've tried reinstalling , repairing vs2012 no effect. simplest console application show same error, it's not specific project , has problem system configuration. @ point i'm clueless module visual studio failing load - google hasn't provided solutions either. the possible link recent removal of older .net framework redistributable packages (since i've got .net 4.5 sdk , multi-target pack, figured older ones weren't necessary) . i need disassembly view working (it worked quite before) , hoping has come across problem. solved: after downloading visual studio 2012 update 2 , problem solved itself. guess bug vanilla release.

to clear - code running - code proc but if instead change proc.new lambda, i'm getting error argumenterror: wrong number of arguments (1 0) may because instance_eval wants pass self param, , lambda treats method , not accept unknown params? there 2 examples - first working: class rule def get_rule proc.new { puts name } end end class person attr_accessor :name def init_rule @name = "ruby" instance_eval(&rule.new.get_rule) end end second not: class rule def get_rule lambda { puts name } end end class person attr_accessor :name def init_rule @name = "ruby" instance_eval(&rule.new.get_rule) end end thanks you correct in assumption. self being passed proc , lambda being instance_eval 'ed. major difference between procs , lambdas lambdas check arity of block being being passed them. so: class rule def get_rule lambda { |s| puts s.inspect; puts name; } en...

i have uicollectionview added uiview in app working on. displayed in uicollectionview have set of images pulled core data. vertical scrolling works fine scrollbar not display until user touches uicollectionview. how can make sure scrollbar @ right visible indication given user scrollable? you can't make them visible. instead, can flash them once, when user first presented collection view notify them, view can scrolled. since uicollectionview subclass of uiscrollview can this: [mycollectionview flashscrollindicators]; check out settings app instance. when go settings list longer screen, scroll indicator flashed once.

today, asked me, how char ** objects saved in memory or in binary files. tested following code snippet: char **array = (char *)malloc(3 * sizeof(char *)); array[0] = "foo"; // length: 3 array[1] = "long string"; // length: 11 array[2] = "bar"; // length: 3 => full length: 17 int length = 17; i write array file: file *file = fopen(...); fwrite(array, length, 1, file); fclose(file); the great thing when read again array file following code, string lengths read without saving more 17 bytes. file *file = fopen(...); int length = 17; char **array = (char *)malloc(length); int index = 0; int parsedlength = 0; while (parsedlength < length) { char *string = array[index]; int stringlength = strlen(string); printf("%i: \"%s\" (%i)\n", index, string, stringlength); parsedlength += stringlength; ++index; } i output equals: 0: "foo" (3) 1: "long s...

i've noticed if foreign https: site links non-https site, don't in http referer header @ all. i've experienced access.log , presume same happens javascript's document.referrer , too. so, if referrer https, there no way information it? not hostname / domain name? or possible somehow @ least domain, javascript? also, presume running own site https isn't going solve issue me, correct? you should check answer : get referrer url - visitors coming paypal (https) in case site uses http (not https) , referer uses https, there no referrer being sent! http rfc - 15.1.3 encoding sensitive information in uri's states: clients should not include referer header field in (non-secure) http request if referring page transferred secure protocol. so way referrer use https on site.
