With the decline of Flash and the explosive rise of mobile devices, more and more content is being delivered as HTML5 video. You can optimize the speed of your site by replacing animated GIF video clips with HTML5 videos. However, video files themselves have a number of optimizations that you can make to improve their performance. One of the most important is that video files must be properly optimized for streaming online as HTML5 video. Without this optimization videos can be delayed for hundreds of milliseconds and megabytes of bandwidth can be wasted by visitors just trying to play your videos. In this post I will show you how to optimize your video files for fast streaming. How MP4 Streaming Works The HTML5 video is a cross-browser way to watch video without needing a plug-in like Flash. As of 2016, H.264 encoded video stored in an MP4 container file (which I’ll just simply call an MP4 video) has emerged as the standard format for all online HTML5 video. So when we talk about optimizing HTML5 video, what we are really talking about is how to optimize an MP4 video for faster playback. And the way we do that has to do with the structure of the MP4 file, and how streaming video works. MP4 files consist of chunks of data called atoms. There are atoms to store things like subtitles or chapters, as well as obvious things like the video and audio data. Meta data about where the video and audio atoms are, as well as information about how to play the video like the dimensions and frames per second, is all stored in a special atom...

Introduction Version control systems can go a long way in preventing developers from pulling their hair out while trying to analyze alterations and contributions made to the shared code. Simply put, a VCS is a pivotal constituent of the software configuration management system that caters to the change management needs on a project. The changes/revisions/updates made are identifiable via letter codes or numbers. Information like time stamps and the identity of the change maker is also maintained. In this tutorial, one of the most frequently used version control systems – GIT will be talked about. You will learn GIT basics like how to install GIT on different systems and how to use it properly. What is GIT? In 2005, Linus Torvalds (the man known for creating the Linux OS kernel) developed GIT and since then, it has been actively maintained by Junio Hamano, a Japanese software engineer. Today, GIT is one of the most famous open-source version control systems and millions of projects around the world rely on GIT for their version control (this includes both commercial and open-source projects). GIT is a completely free software and can be downloaded for Mac, Linux, Windows, and Solaris from the official website. Some of the worth-mentioning features of GIT are: A distributed version control system, GIT follows a peer to peer approach unlike others such as Subversion (SVN) that follow a client-server based model.GIT allows developers to have a plethora of completely independent code branches. Creating, deleting and merging of these branches is seamless and takes no time.In GIT, all operations are atomic; that means that an action can either succeed completely or fail (without making any...
