If you have PHP installed locally and you would like to use PHP's built-in development server to serve your application, you may use the serve Artisan command. This command will start a development server at http://localhost:8000: php artisan serve Of course, more robust local development option...

The basic example Open routes/web.php file and paste the following code in file: Route::get('helloworld', function () { return '<h1>Hello World</h1>'; }); here 'helloworld' will act as page name you want to access, and if you don't want to create blade file and still want to ...

Open routes file. Paste the following code in: Route::get('helloworld', function () { return '<h1>Hello World</h1>'; }); after going to route http://localhost/helloworld it displays Hello World. The routes file is located /routes/web.php

Accessing pages and outputting data is fairly easy in Laravel. All of the page routes are located in app/routes.php. There are usually a few examples to get you started, but we're going to create a new route. Open your app/routes.php, and paste in the following code: Route::get('helloworld', functi...

Bullet This one particularly blew my mind. The bullet gem helps you kill all the N+1 queries, as well as unnecessarily eager loaded relations. Once you install it and start visiting various routes in development, alert boxes with warnings indicating database queries that need to be optimized will p...

In this example we will set up a geospatial database, import data from 2 different sources, and view the results in an application called QGIS. This guide is explicitly written for linux-machines, if you operate on another platform, some commands or paths might not work as expected. In order to vie...

Backreferences "Backreferences" are references in a search regex to capture groups in the same search regex. The "search regex" is the regex used in the "Find" field of the Find/Replace dialog box. Here is the most common backreference syntax: Absolute: (group one)...

A regex in Notepad++ may have as many capture groups as desired. (one)(two)(three)...(nine)(more than nine groups!)... Anonymous capture groups use the standard syntax: (group) Named capture groups may use either of following syntax formats: (?<name>group) (?'name'group) Anonymo...

It's entirely possible to use PICO-8 as an interactive shell, but you probably want to tap into the game loop. In order to do that, you must create at least one of these callback functions: _update() _update60() (after v0.1.8) _draw() A minimal "game" might simply draw something on...

Although it's not officially supported, you can use mouse input in your games: function _update60() x = stat(32) y = stat(33) if (x>0 and x<=128 and y>0 and y<=128) then -- left button if (band(stat(34),1)==1) then ball_x=x ball_y=y...

Typically we represent an anary tree (one with potentially unlimited children per node) as a binary tree, (one with exactly two children per node). The "next" child is regarded as a sibling. Note that if a tree is binary, this representation creates extra nodes. We then iterate over the s...

Plugins are .py files that changes the behaviour of Sublime Text 3. They are written, as you probably guessed, in Python. Because there is plenty of different sort of plugins (text manipulation, linting, formatting, preview, etc), we will not give any example to not over populate this page with a h...

A package is a folder that can contain anything that is listed in these examples (and other thing that can have nothing to do with Sublime Text 3, such as a gulpfile.js if you're automating some tasks). You can install any package using the create Package Control. A .sublime-package ? Maybe you'v...

Along with other more advanced text editors, Atom allows developers to open a single file or a directory. Opening Files To open files with Atom, either use File > Open File... in the menu as show below: or use the faster keyboard shortcut: Ctrl+O (For Mac OS: ⌘+O). This will open a file expl...

The primary reason to use interfaces to achieve polymorphism and provide developers to implement on their own way in future by implementing interface's methods. Suppose we have an interface and three classes: interface Connector{ doConnect(): boolean; } This is connector interface. Now we...

TypeScript supports interfaces, but the compiler outputs JavaScript, which doesn't. Therefore, interfaces are effectively lost in the compile step. This is why type checking on interfaces relies on the shape of the object - meaning whether the object supports the fields and functions on the interfac...

const { remote } = require("electron"); // <- The Node.js require() function is // added to JavaScript by electron function setProgress(p) { // p = number from 0 to 1 const currentWindow = remote.getCurrentWindow(); currentWindow.setProgre...

This is a unit test of a component that has Store as a dependency. Here, we are creating a new class called MockStore that is injected into our component instead of the usual Store. import { Injectable } from '@angular/core'; import { TestBed, async} from '@angular/core/testing'; import { AppComp...
