on server side sanitise coming in. on angular app client side i've done same in instances e.g. contact forms thinking shouldn't apply every input field? so i've seen $sanitize('some string') there way apply @ top app level rather having enter every instance input fields is? (assuming wise thing - if not keen hear suggestions). thanks. you can create directive call "input", apply inputs of app. inside directive can add parser $ngmodel apply automatically $sanitize when value changes. it looks this: myapp.directive('input', function($sanitize) { return { restrict: 'e', require: '?ngmodel', link: function (scope, element, attrs, ngmodel) { if(ngmodel !== undefined){ ngmodel.$parsers.push(function(value){ return $sanitize(value); }); } } }; });

https://en.wikipedia.org/wiki/yacht_(dice_game) i created 5 dice in c++ program , each roll random numbers 1-6. if 1's simple. it's just: if (dice1 == 1 && dice2 == 1 && dice3 == 1 && dice4 == 1 && dice5 == 1) { int total = 50; } also, summing dice easy too. how write if-statement "if 2 4 dice same sum dice"? there simple way that? try use tables , make variable count 1 in table. u can compare it.

i want make queue using linked lists. there numerous algorithms out there that. i'm curious in how make relative priority queue. maybe there special name type of queue, don't know it, , haven't had luck googling solution. anyways, let's have struct, represent node of list. struct node { int value; node* next; } if want create priority queue (where element least value first), when insert example 5 7 1 8 2, list should this: 1 -> 2 -> 5 -> 7 -> 8 it's not hard implement that. want - when insert first element, other elements should have value relative previous element. so, in example, list/queue contain following values: 1 -> 1 -> 3 -> 2 -> 1 i'm not sure how implement that? following idea applicable: in node struct add field, represent original value. find position of node i'm inserting same way when creating ordinary linked list, , say temp->value = temp->originalvalue - previous->originalvalue;...

i'm trying use array while read , entire array output @ once. #!/bin/bash declare -a arr=('1:one' '2:two' '3:three'); while read -e ; echo $it done <<< ${arr[@]} it should output each value separately (but doesn't), maybe while read isn't hot ticket here? for case, easier use for loop: $ declare -a arr=('1:one' '2:two' '3:three') $ in "${arr[@]}"; echo $it; done 1:one 2:two 3:three the while read approach useful (a) when want read data file, , (b) when want read in nul or newline separated string. in case, however, have data in bash variable , for loop simpler.

if have weighted undirected graph no negative weights, can contain multiple edges between vertex , self-loops, can run dijkstra algorithm without problem find minimum path between source , destination or exists counterexample? my guess there not problem, want sure. if you're going run dijkstra's algorithm without making changes graph, there's chance you'll not shortest path between source , destination. for example, consider s , o. now, finding shortest path depends on edge being being traversed when want push o queue. if code picks edge weight 1, you're fine. if code picks edge weight 8, algorithm going give wrong answer. this means algorithm's correctness dependent on order of edges entered in adjacency list of source node.

i have inherited else's code. used cmake build fragments c++ , fragments java/android. cannot believe have used notepad , windows explorer manage package/class structure , implementation. there code manager tool or ide allows put java code in 1 package , c++ in package? cmake scripts build projects separately, of course. cmake build tool. you can use ide write code , use different tool build it. eclipse supports both java , c++, wouldn't recommend either.

i have wp template assign pages. template ie. display woocommerce products have same master category name pages name itself. by far have tried using code, no output: $idobj = get_category_by_slug($pagename); $id = $idobj->term_id; echo ": ". $id; unfortunately, echo not display anything. echoing $pagename works, , returns me slug of page. any way make work? with custom taxonomy recommended use get_term_by() instead : $category = get_term_by( 'slug', $pagename, 'product_cat' ); $cat_id = $category->term_id reference: get category id category slug…

ok, i've revised of techniques implement inheritance in javascript oop. java programmer, i'm interested in classical approach here's problem; want create animal class (i know it's not real class, let me use term) this: function animal(name){ this.name = name; } animal.prototype.getname = function() { return this.name; } it important note concrete class in first intention, want instantiate it, not use superclass. may create several animal instances, each 1 own name. a possible way extend class following: function cat(name, owner) { this.name = name; this.owner = owner; } // alternative 1: cat.prototype = object.create(animal.prototype); // alternative 2: cat.prototype = new animal('lola'); // end of alternatives cat.constructor.prototype = cat; cat.prototype.jump = function() { alert(this.name + " jumping"); } with alternative 1 inherit methods of superclass, in fact need redefine name property in cat....
