If your project depends on the external libraries, you should first install them with opam. Assuming your dependencies are foo and bar and the main entry point of your project is foobar.ml you can then build a bytecode executable with ocamlbuild -use-ocamlfind -pkgs 'foo,bar' foobar.byte Warnin...

In attempt to send a response asynchronously from chrome.runtime.onMessage callback we might try this wrong code: chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) { $.ajax({ url: 'https://www.google.com', method: 'GET', success: functio...

Using filterUsingPredicate: This Evaluates a given predicate against the arrays content and return objects that match. Example: NSMutableArray *array = [NSMutableArray array]; [array setArray:@[@"iOS",@"macOS",@"tvOS"]]; NSPredicate *predicate = [N...

let minimumVersionString = "3.1.3" let versionComparison = UIDevice.current.systemVersion.compare(minimumVersionString, options: .numeric) switch versionComparison { case .orderedSame, .orderedDescending: //current version is >= (3.1.3) break case .orderedA...

Foreword Git can work with video game development out of the box. However the main caveat is that versioning large (>5 MB) media files can be a problem over the long term as your commit history bloats - Git simply wasn't originally built for versioning binary files. The great news is that since...

To send an immediate message with data to JavaScript, you have to trigger an action from your init. init : ( Model, Cmd Msg ) init = ( Model 0, send SendOutgoing ) send : msg -> Cmd msg send msg = Task.perform identity identity (Task.succeed msg)

By default, ui-router encodes the slash / inside parameters. If you want to send a path in the URL, you need to define a custom parameter type. Define: module.config(['$urlMatcherFactoryProvider', function($urlMatcherFactory) { $urlMatcherFactory.type('path', { decode: function(val) { retu...

#include <stdio.h> #define ARRLEN (10) int main (void) { int n[ ARRLEN ]; /* n is an array of 10 integers */ size_t i, j; /* Use size_t to address memory, that is to index arrays, as its guaranteed to be wide enough to address all of the possible availab...

A distinctive syntactic peculiarity of C is that declarations mirror the use of the declared object as it would be in a normal expression. The following set of operators with identical precedence and associativity are reused in declarators, namely: the unary * "dereference" operator wh...

Wikipedia currently defines a pure function as follows: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change while program execution proceeds or between different executions...

Using scenario you can perform validation on different situation Define scenario in model class class User extends \yii\db\ActiveRecord { public static function tableName() { return 'user_master'; } // define validation in rule() function public ...

Using the Vector.<T> type and the for each loop is more performant than a conventional array and for loop: Good: var list:Vector.<Sprite> = new <Sprite>[]; for each(var sprite:Sprite in list) { sprite.x += 1; } Bad: var list:Array = []; for (var i:int = 0; i < ...

If you do not require an array to be in any particular order, a little trick with pop() will afford you enormous performance gains compared to splice(). When you splice() an array, the index of subsequent elements in that array needs to be reduced by 1. This process can consume a large chunk of tim...

If you have a value that you use often, you can store it in a variable. You could use this to define color schemes, for example. You would only have to define your scheme once and then you could use it throughout your stylesheets. To define a variable, you must prefix its name with the $ symbol. (L...

There are many ways find the location of a value in an array. The following example snippets all assume that the array is one of the following: String[] strings = new String[] { "A", "B", "C" }; int[] ints = new int[] { 1, 2, 3, 4 }; In addition, each one sets...

So you've uploaded your files to a folder say /backend/web/uploads/ and you want these uploads to be visible on the frontend too. The easiest option is to create a symlink in the frontend that links to the backend: ln -s /path/to/backend/web/uploads/ /path/to/frontend/web/uploads In your views y...

SharedPreferences allows you to store primitive data types only (boolean, float, long, int, String, and string set). You cannot store more complex objects in SharedPreferences, and as such is really meant to be a place to store user settings or similar, it's not meant to be a database to keep user d...

If you need to count distinct characters then, for the reasons explained in Remarks section, you can't simply use Length property because it's the length of the array of System.Char which are not characters but code-units (not Unicode code-points nor graphemes). If, for example, you simply write tex...

If you need to count characters then, for the reasons explained in Remarks section, you can't simply use Length property because it's the length of the array of System.Char which are not characters but code-units (not Unicode code-points nor graphemes). Correct code is then: int length = text.Enume...
