As a WebSockets Proxy - NGINX. The WebSocket protocol provides a way of creating web applications that support realtime bi-directional communications between clients and servers. Part of HTML5, WebSockets makes it much easier to develop these types of applications then the methods previously available. Most modern browsers support WebSockets including Firefox, Internet Explorer, Chrome, Safari and Opera and more and more server application frameworks are now supporting WebSockets as well. For enterprise production use, where multiple WebSocket servers are needed for performance and high availability, a load balancing layer that understands the WebSocket protocol is required, and NGINX has supported WebSockets since NGINX 1.3 and can act as a reverse proxy and do load balancing of WebSocket applications.
The WebSocket protocol is different than the HTTP protocol, but the WebSocket handshake is compatible with HTTP, using the HTTP Upgrade facility to upgrade the connection from HTTP to WebSocket. For Debian/Ubuntu:

CSS3 transitions and animations are currently the preferred method for creating lightweight animations on websites. Unfortunately, many developers find their syntax to be complex and confusing. If this sounds like you, Move.js may be the perfect solution for you. Move.js is a simple JavaScript library that creates CSS3 animations using simple functions. This tutorial explores the basics of Move.js, and provides a live demo of Move in action. The Basics Move.js provides a simplified JavaScript API for creating CSS3 animations. With Move.js we can simply use the set() method to achieve the same results, as shown below. Getting Started First, visit the Move.js GitHub page and download the latest package. We have defined a div element of class box, and a link with the ID playButton that will be used for our demo purpose.
Our HTML page should now look like the following figure. Now, let’s write our first Move.js snippet. The complete code, after adding the Move.js code, is shown below. skew(x, y)
Express-di by luin. Installation npm install --save express-di Usage To get started simply require('express-di') before var app = express(), and this module will monkey-patch Express, allowing you to define "denpendencies" by providing the app.factory() method, after which you can use the "denpendencies" in you routes following the Dependency Injection pattern(DI).
Example In the past, if you want to pass variables between middlewares, you have to tack on properties to req, which seems odd and uncontrollable(that you couldn't point out easily which middleware add what properties to req). After using express-di, you can do this: Define a dependency The app.factory(name, fn) method is used to define a dependency. Arguments name: The name of the dependency.fn: A function that is like a typical express middleware, takes 3 arguments, req, res and next, with a subtle difference that the next function takes 2 arguments: an error(can be null) and the value of the dependency. Default dependencies Cache Where can I use DI? Test. Service Oriented Architectures with Symfony2 — Alessandro Nadalin. Fn.js | A JavaScript library built to encourage a functional programming style & strategy.
Fn.js is an opinionated JavaScript library that pushes you to to adopt strategies that encourage a functional programming style. I do not purport to be a master of functional programming especially as it relates to mathematical concepts, and I do not expect you to be either.
Rather, fn.js provides functionality that you may be used to in Underscore.js or Lodash, but in a way that lends itself to greater self-composability and support of core functional programming tenets. Core Functional Programming Tenets Avoidance of Side Effects The concept of side effects is closely related to the design pattern of the Single Responsibility Principle, or as I like to say: "A function should do one thing, and do it well.
" Referential Transparency In object-oriented or classic programming applications, the flow of code is controlled by creating objects that mimic real-world or virtual beings. Immutability Immutability, or the inability for variables to changes their values once created.
PhpStorm - Top Productivity Hacks and Shortcuts. We all have our favorite IDEs/editors when coding. Mine is PhpStorm, and it took a while to master all its shortcuts and establish a rapid workflow. In this article, I’ll share some keyboard shortcuts and tips with you which you should make part of your regular routine if you, too, do your work in this IDE. This article was partially inspired by this Reddit thread, and will be mentioning and demonstrating some of the shortcuts found there as well. Note that as I’m doing my development on Linux in a vagrant box hosted on Windows, my shortcuts might be different from yours.
Keyboard shortcuts and hacks PhpStorm’s high configurability (it’s almost an “Android” of the PHP IDE world) lets you fine tune it to infinity – you can make it into a tool so personal, it might seem like a different IDE to anyone opening your settings. As described in this tweet, you can now “search everywhere” by double-tapping Shift. Plugins PhpStorm has a wealth of various language plugins.

Here are 10 of the best SCSS utilties I find myself using most often. You can download the entire file to use in your projects from the UtilityBelt Repository on Github. Download “UtilityBelt.scss”UtilityBelt.zip – Downloaded 109 times – 10 kB Triangle Sagi likes to call this the chupchick (don’t ask me why). It’s great for adding a point to tooltips or some extra flair to a component, but can also be used as a standalone icon.
To make this mixin really flexible, it accepts a parameter, which can be any of the four cardinal directions. A descriptive div that uses the triangle mixin to point to something. Currency I wanted to be able to display a currency symbol on any type of text element without breaking the design, but also to be able to switch it easily. Example Usage <body class="USD"><span class="price">45</span></body> .price { @extend %currency; } Example usage Hover over me. Text to ASCII Art Generator (TAAG)
JavaScript Debounce Function. One of the biggest mistakes I see when looking to optimize existing code is the absence of the debounce function. If your web app uses JavaScript to accomplish taxing tasks, a debounce function is essential to ensuring a given task doesn't fire so often that it bricks browser performance. For those of you who don't know what a debounce function does, it limits the rate at which a function can fire.
A quick example: you have a resize listener on the window which does some element dimension calculations and (possibly) repositions a few elements. That isn't a heavy task in itself but being repeatedly fired after numerous resizes will really slow your site down. Why not limit the rate at which the function can fire? Here's the basic JavaScript debounce function (as taken from Underscore.js): function debounce(func, wait, immediate) { var timeout; return function() { var context = this, args = arguments; clearTimeout(timeout); timeout = setTimeout(function() { timeout = null; if (!

Videoconverter.js - Convert Videos In Your Web Browser. Videoconverter.js is a program that lets you process videos in your browser. View a DemonstrationView a Sample Application or view code on github About [#] Videoconverter.js was originally conceived and implemented for a project in Node Knockout 2013 called Video Funhouse. The idea for the application was to try and convert any video file into another video format, while allowing filters to be applied to the video – all inside of the browser, without uploading anything.
And to build it in a single weekend. This is a huge task, and we knew that existing libraries like FFmpeg would do a great job. Here is a video demonstrating the sample application we made with this library over the weekend: Why? Why would you compile FFmpeg into JavaScript? Who? Most of the grunt work has been done by @bgrins and @aaronm67. How Big is the JavaScript File? The ffmpeg.js file is around 24 MB or so. Should I Use This? Feel free to use this program, but keep in mind the following things: Pontential Uses [#]
