i'm trying create following structure of classes using backbone.js inheritance model: backbone.events -> parent -> child child should call initialize parent, unfortunately not work. parent methods , properties not visible. please help. my code var parent = function() { this.initialize.apply(this, arguments); }; _.extend(parent.prototype, backbone.events, { initialize: function() { // parent init }, }); var child = function() { this.initialize.apply(this, arguments); }; _.extend(child.prototype, parent, { /* inherits parent */ initialize: function() { // need call `parent init` code // need init myself (child) // not work // parent methods , properties not visible parent.prototype.initialize.call(this, arguments); } }); just use following approach: function parent() { this.initialize.apply(this, arguments); }; _.extend(parent.prototype, backbone.events, { init

take follow situation in mind: 1) user login in windows desktop machine active directory domain. 2) after logged in, user open web browser , type , url need login web app current login/session/token of active directory, automatically. example: after log on active directory, user open url http://intranet.myplace.com , , first page opened need detect credentials of current logged in user of ad. it possible ? cant find nothing acess ad credentials javascript. no, not possible client approach. regardless of using javascript or activex: need on server side. besides activex limit browsers, can ok in company environment think in. javascript not able query login context of client. , if should verify on server. to achieve describe need use kerberos or challenge response based techniques offered iis or apache. if want secure approach find able configure server.

i'm building app using processwire . i'm using servicepages module expose data rest-like api. however, files seem outputted this: reel_poster: { basename: "breakdown-2015-poster.jpg", description: "", tags: "", formatted: false, modified: 1468541707, created: 1468541707 } how actual path / url of file referenced? need path in js app, can't use php api. i've posted this on forums , seems there's not lot of activity there. so, if read this forum post correctly , way create url assembling manually. need 3 things that: the base path file assets. the id of page field attached. the image name. we know base path file assets /site/assets/files/ . can this, given have page object api: var basepath = '/site/assets/files/'; var imagepath = basepath + page.id + '/' + page.image_field.basename; this should work. think. yes. tested , works.

i'm trying write code in c calculate accurate of stirling's approximation 1 12. here's code: #define pi 3.1416 #define eulernum 2.71828 float stirling_approximation(int n) { int fact; float stirling, ans; fact = factorial(n); stirling = sqrt(2.0*pi*n) * pow(n / eulernum, n); ans = fact / stirling; return ans; } int factorial(int input) { int i; int ans = 0; (i = 1; <= input; i++) ans += i; return ans; } int main(void) { int n; printf(" n\t ratio\n"); (n = 1; n <= 12; n++) { printf("n: %2d\t %f\n", n, stirling_approximation(n)); } return 0; } i'm getting recursive calculation correctly, stirling's approximation method value way off. , what's more puzzling answers n = 1, 3 correct. i think has calling approximation function main function. know must such simple mistake i've been trying fix entire day! please me? thank you! you inco

while checking source code of java's bigdecimal class, surprised not declared final class : class bigdecimal public class bigdecimal extends number implements comparable<bigdecimal> immutable , arbitrary-precision signed decimal numbers. (from oracle docs ) is there specific reason or did developers forget add keyword? practice not declare immutable classes final? the same goes biginteger , not string declared final. quote https://blogs.oracle.com/darcy/entry/compatibly_evolving_bigdecimal : however, there possible complication here since bigdecimal not final , since has public constructors, can subclassed. (as discussed in effective java, item 13, favor immutability, this design oversight when class written .) (emphasis mine). since java has favored backward compatibility, making final out of question: break existing subclasses. that said, when using date, assume no-one ever subclasses bigdecimal, , bigdecimal should used if im
