31,136,934 | 0 | <p>You can use <code>new Function</code> for that. It wraps your code into a function like this:</p> <pre><code>var fn = new Function(output); fn(); </code></pre> <p>Or shorter:</p> <pre><code>new Function(output)(); </code></pre> <p>Which is the equivalent of:</p> <pre><code>function(){ var newElement = document.createElement("h1"); var element = document.createTextNode("Hello World!"); newElement.appendChild(element); document.body.appendChild(newElement); } </code></pre> |
17,968,979 | 0 | <p>Since your tree is essentially an object array, where each object has a label and an optional child array, what you need to prune are array elements, either in the main tree array or in one of it's branches. </p> <p>You definitely do not want to use <code>delete</code> to delete array elements, since that leaves you with a sparse array. Instead, you should <code>splice</code> out array elements. </p> <p>You should, on the other hand, use <code>delete</code> to remove object properties, like <code>children</code> once they're empty. Here's the code I would use:</p> <pre><code>function prune(array, label) { for (var i = 0; i < array.length; ++i) { var obj = array[i]; if (obj.label === label) { // splice out 1 element starting at position i array.splice(i, 1); return true; } if (obj.children) { if (prune(obj.children, label)) { if (obj.children.length === 0) { // delete children property when empty delete obj.children; // or, to delete this parent altogether // as a result of it having no more children // do this instead array.splice(i, 1); } return true; } } } } </code></pre> <p>Now assuming your tree was called <code>tree</code> and the label you wanted pruned was <code>node3</code>, you would call prune like so:</p> <pre><code>var wasItPruned = prune(tree, "node3"); </code></pre> |

8,791,424 | 0 | Setting ASP.NET Cache control headers <p>In my asp.net forms app. I'm trying to prevent caching of certain pages. to do so I've set a series of cache control headers using Response.AppendHeader e.g.</p> <pre> protected override void OnLoad(Eventargs e) { ... Response.ClearHeaders(); Response.AppendHeader("Cache-Control","no-cache"); .... base.OnLoad(e); } </pre> <p>Trouble is when I view my site and look at the Net tab in the Firefox console to view the request/response headers I see a behavior as follows:</p> <ol> <li><p>a POST request/response for the page1.aspx which triggers a redirect (to page2.aspx) the response here contains the correct headers. </p></li> <li><p>a GET request/response for page2.aspx associated response has the cache-control header just has a value 'pre-check=0'</p></li> </ol> <p>That second request seems to allow the caching to happen for the page.. note: page1.aspx and page2.aspx both have the OnLoad logic I describe above. Also if I take some action on page2.aspx, the POST response will again have the correct headers.</p> <p>What am I missing here? My expectation was that with the logic in OnLoad should mean that I always get the headers in the response and therefore 'always' get the current version of the page? </p> <p>What I'm seeing is firefox loading it's cached version of the page.</p> <p>I'm considering creating a random identifier in the request url to force the matter, but that seems a little heavy handed.</p> <p>-----update----- It seems that, this may be related to having the caching code in 'OnLoad'. I've added these headers to the Page_Load() of the page and it works fine? any thoughts.</p> |

11,084,216 | 0 | Select statement to get a specific row from an inner join <p>The question I have is kind of simular to this one - <a href="http://stackoverflow.com/questions/10914079/mysql-select-1-row-from-inner-join">MySQL select 1 row from inner join</a></p> <p>However, it was never really answered in the way that I needed it. So I thought I would ask.</p> <p>I have a table A (tableA) and this table has a load of states in tableB. New states keep being added all the time.</p> <p>TableB has a column 'State' which has a foreign key to TableA.Id. This table B has a value and timestamp</p> <p>I am trying to get ONE query which will bring back ALL values in TableA, with an inner join to bring the LATEST 'value' of those rows from tableB. The latest being the one with the latest time.</p> <p>I know how to do an inner join where it needs to be, and I know how to order a table to bring back the latest 'time' row, however I dont know how to put these two together and create a single query.</p> <p>I'm sure I will have to have a Select within a select, which is fine. However, what I am trying to avoid is to bring a DataTable back with all my results from TableA and do a query for each of those on tableB seperately.</p> <p>Any ideas?</p> <p>EDIT - I have made a mistake with the question, I only really noticed when trying to implement one of the answers.</p> <p>I have a foreign key between TableA.id and TableB.proId</p> <p>TableA - 'Id', 'Name' TableB - 'Id', 'proId', 'State', 'time'</p> <p>I want to bring back all values of TableA with a join on B, to bring back the 'State' of the Max time</p> |

4,895,049 | 0 | <p>I'm assuming the solution you're mentioning in the comment is something like this:</p> <p>Start at the left or right (so index = 0), and scan which bits are set (upto 100 operations). Name that set x. Also set a variable block=0.</p> <p>At index=1, repeat and store to set y. If x XOR y = 0, both are identical sets, so move on to index=2. If it x XOR y = z != 0, then range [block, index) is contiguous. Now set x = y, block = index, and continue.</p> <p>If you have 100 bit-arrays of length 22 each, this takes something on the order of 2200 operations.</p> <p>This is an optimum solution because the operation cannot be reduced further -- at each stage, your range is broken if another set doesn't match your set, so to check if the range is broken you must check all 100 bits.</p> |

This navbar relies on a controller (let's say NavBarController), and based on the authenticated user, it shows some buttons or not. The problem is that when The user Log's in, the next page is loaded on then ng-view, but the NavVar controller do not know about this, so it does not refresh it's $scope, therefore the proper buttons wont show up.</p> <p>I guess my question is: How can I trigger a "Refresh" action on a controller based on another controller's function. ? is that event possible ? or do I have to repeat the nav bar inside every controller's html ?</p> <p>Here's my main html: </p> <pre><code><div ng-app='theApp'> <div data-ng-controller="NavBarController"> <nav class="navbar navbar-default" role="navigation"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand">The App</a> </div> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav"> <li class="active" ng-show="user.role == 'admin'"><a href="#">Link visible only by admin</a></li> <li><a href="#">Link visible by all</a></li> </ul> <ul class="nav navbar-nav navbar-right"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">{{ user.name }} <b class="caret"></b></a> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#" ng-click="LogOut()">Log out</a></li> </ul> </li> </ul> </div> </div> </nav> </div> <div ng-view></div> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js" /> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular-route.min.js" /> <script src="app/app.js"></script> <!-- controllers --> <script src="app/controllers/membershipController.js"></script> <script src="app/controllers/navBarController.js"></script> <!-- factories --> <script src="app/factories/membershipFactory.js"></script> <!-- services --> <script src="app/services/userService.js"></script> </div> </code></pre> <p>Now, the NavBarController is something like: </p> <pre><code>(function () { var NavBarController = function ($scope, UserService) { function init() { $scope.user = UserService.getUser(); /* functions */ $scope.LogOut = function () { UserService.clearUser(); }; } init(); } NavBarController.$injenct = ['$scope', 'UserService']; angular.module("theApp").controller('NavBarController', NavBarController); }()); </code></pre> <p>The initialization of angular is like: </p> <pre><code>(function() { var theApp = angular.module("theApp", ['ngRoute', 'ngCookies', 'ui.bootstrap']); angular.module("theApp").config(function($routeProvider){ $routeProvider .when('/', { controller: 'MembershipController', templateUrl: 'app/views/login.html' }) .when('/index', { templateUrl: 'app/views/index.html' }) .otherwise ( { redirectTo: '/' } ); }); }()); </code></pre> <p>login.html is just a typical login password page, that triggers the MembershipController Authenticate() function.

Can I do that.</p> <p>for being more clear:</p> <p>I want the trained machine learning program to be launched only once in the server and the web portal should receive the inputs parameters from clients and send back the prediction after interacting with the program .

But the stack just has to be at the top of a large enough chunk of available address space in the memory map for that particular process. It doesn't have to be at the very top. If you need 1MB for the stack, and you have 1MB, you can just reserve that 1MB and have the stack start at the top of it.</p> <blockquote> <p>How does the sp register work if there are multiple call stacks?

There are some kernel threads that do only kernel tasks, but also user-space threads also run in kernel space to run the OS code. Pure kernel threads have their own stacks somewhere in kernel memory.
