Introduction HTML5 canvas, which started as an experiment from Apple, is the most widely supported standard for 2D immediate mode graphics on the web. Many developers now rely on it for a wide variety of multimedia projects, visualizations, and games.
The HTML5 WebSockets specification defines an API that enables web pages to use the WebSockets protocol for two-way communication with a remote host. It introduces the WebSocket interface and defines a full-duplex communication channel that operates through a single socket over the Web. HTML5 WebSockets provide an enormous reduction in unnecessary network traffic and latency compared to the unscalable polling and long-polling solutions that were used to simulate a full-duplex connection by maintaining two connections.
One of the coolest new features of HTML5 is WebSockets, which let us talk to the server without using AJAX requests. In this tutorial, we’ll review the process of running a WebSocket server in PHP, and then building a client to send and receive messages to it over the WebSocket protocol. What are WebSockets? WebSockets is a technique for two-way communication over one (TCP) socket, a type of PUSH technology. At the moment, it’s still being standardized by the W3C; however, the latest versions of Chrome and Safari have support for WebSockets. What do WebSockets Replace?
The Problem: Low Latency Client-Server and Server-Client Connections The web has been largely built around the so-called request/response paradigm of HTTP. A client loads up a web page and then nothing happens until the user clicks onto the next page. Around 2005, AJAX started to make the web feel more dynamic. Still, all HTTP communication was steered by the client, which required user interaction or periodic polling to load new data from the server.

This talk explores when to start performance testing, how to avoid the common pitfalls, how to profile when the results cause your team to pull a funny face, and what you can do about that funny face.

First Drafts of Three Audio API Specifications Published 15 December 2011 The Audio Working Group has published three First Public Working Drafts to provide an advanced audio API for the Web: the Web Audio API and MediaStream Processing API specifications each define a different approach to process and synthesize audio streams directly in script.
Daniel Bailey in Business Products on May 27 The collection of technologies that will redefine much of the Internet as we perceive it today is going into a public review phase that invites comments and hopes for feedback on outstanding issues to enable a standardization by 2014. The Official HTML5 Logo The development of a standard is never anything that happens overnight and even if it appears that HTML5 is already a standard, it is in dire need of much more control and strong definitions for a final standard.
One of things that we need to get used to when making the switch from HTML4/XHTML to HTML5 is the way HTML5 validation works, because it’s drastically different from what we’ve become accustomed to in previous iterations of web markup. First, it should be noted that the W3C’s HTML5 validation engine is “experimental”, so it’s a work in progress that will likely see many changes over the next year or more. Also, we shouldn’t refer to it as a “validator” anymore; it’s now more accurately referred to as a “conformance checker” (although for simplicity I’ll be using the term “validation” and its derivatives).
