i have function foo makes ajax request. how can return response foo ? i tried return value success callback assigning response local variable inside function , return one, none of ways return response. function foo() { var result; $.ajax({ url: '...', success: function(response) { result = response; // return response; // <- tried 1 } }); return result; } var result = foo(); // ends being `undefined`. -> more general explanation of async behavior different examples, please see why variable unaltered after modify inside of function? - asynchronous code reference -> if understand problem, skip possible solutions below. the problem the a in ajax stands asynchronous . means sending request (or rather receiving response) taken out of normal execution flow. in example, $.ajax returns , next statement, return result; , executed before function passed success callback ca...

when trying figure out how configure aws_instance aws vpc following errors occur: * error launching source instance: invalidparametercombination: parameter groupname cannot used parameter subnet status code: 400, request id: [] or * error launching source instance: invalidparametercombination: vpc security groups may not used non-vpc launch status code: 400, request id: [] this due how security group associated instance. without subnet ok associate using security group's name: resource "aws_instance" "server" { ... security_groups = [ "${aws_security_group.group_name.name}" ] } in case subnet associated cannot use name, should instead use security group's id: security_groups = [ "${aws_security_group.group_name.id}" ] subnet_id = "${aws_subnet.subnet_name.id}" the above assumes you've created security group named group_name , , subnet named subnet_name

consider: angular .module('app', []) .controller('maincontroller', function($scope) { $scope.$watch('bool', function(newval, oldval) { }); console.log($scope); }); and <body ng-controller='maincontroller'> <p ng-class="{'blue': bool, 'red': !bool}">ngclass</p> <p ng-show='bool'>ngshow</p> <input type='checkbox' ng-model='bool' /> </body> plnkr of above it seems there 3 watchers being created: from $scope.$watch . from ngshow . from ngclass . (note: directives involved in data binding use $scope.$watch internally.) i have thought since they're watching bool property, there'd 1 watcher , it'd have multiple listener callbacks. edit: case it's saying, "has bool changed? if run cb1 . has bool changed? if run cb2 . has bool changed? if run cb3 ." or case it's saying, "has bool ...

i wanted @ source getrowvector method of realmatrix class in apache commons math library. found here: grepcode . for reason though, seemingly none of methods shown have implementation; function prototypes: realvector getrowvector(int row) throws matrixindexexception; after searching though, found java doesn't have prototypes. purpose of code above? there actual implementation somewhere? it's odd because full implementation similar realvector class given i'd expect; it's realmatrix that's this. realmatrix interface. interface defines contract implementations responsible fulfilling, without providing implementation code (although of java8 can have default methods , static methods). can use interface limit how client needs know object it's using. basic example java.util.list, provides common methods accessing , modifying lists, , has multiple implementations, provided in jdk collections library (one list backed array, 1 linked list impleme...

i haven't been able find if possible know if possible make chart title change whatever in cell? example: chart title says "last month returns: costco" "costco" comes cell a2 because change wal-mart , title "last month returns: wal-mart" i think done via macro if can avoid macros that'd awesome. the chart title can linked cell, not combination of text , cell. if cell a2 contains "costco" say, should enter formula in cell b2 (or other cell) formula ="last month returns: " & a2 then select chart title, , while selected type formula bar: =b2 that should it.

i use xcode 6. imagine following scenario: app's base language english , decide add german localisation. have 2 versions of interface.xib . if add ui elements base version, convert german version localisable strings , , changes ported (if strings added, have manually edited of course) but if it's german version of interface.xib edited? how new ui elements english version? can't use same trick, @ least have found no way convert localised strings, xcode has no idea should use remaining german xib , fill in english localised strings. what do, except make ui changes in base version in future? you correct in conclusion. way localization designed in xcode expects originate ui changes in base language.

i looking @ possibility of optimizing execution of of existing code using ternary operators in single command containing if , else blocks. is ternary operator approach faster traditional if / else e.g faster execute of following: first: expr {[info exists arr($var)]? [return $_timeouts($var)] : [puts "no key $var has been set"]} second: if {[info exists arr($var)]} { [return $_timeouts($var)] } else { puts "no key $var has been set" } notice entire expr in ternary operator approach (first) contained in single {} block , hoping faster execute second approach. thanks you can use built-in time command test question. i changed 'puts' different 'return' statement speed of variable exists in array directly compared speed of variable not exist in array. variable arr proc test1 { var } { variable arr expr {[info exists arr($var)] ? [return $arr($var)] : [return -1]} } proc test2 { var } { variable arr if {...

in php function, want return if user not moderator or if user not post author etc. see following basic statement: $mod = false; $status = 'pending'; $currentuser = 22; $author = 22; if ( (!$mod) || ( ($status != 'pending') && ($currentuser != $author) ) ) { return; } so, in example, function should not return because $currentuser $author , $status matches. what doing wrong? (!$mod) true. if condition evaluated true you end having: if ( true || anothercondition ) { return; } it doesn't matter other condition in case. evaluates true your code pretty close need. if ( (!$mod) && ($status != 'pending') && ($currentuser != $author) ) { // if user not moderator , // status not pending , // user not owner, return; }
