Usually, after Sencha conferences, videos are released to give followers a brief rundown of what transpired. One of the presentations on the Sencha Conference 2010 was JavaScript: Under the Hood. Surprisingly, the video and slides of this presentation have received much acceptance from followers. As of now, this presentation is currently on the list of the most popular Sencha’s SlideShare occupying No 2 spot. Due to the level of acceptance of last year’s presentation, there will be explanatory talks about web technologies at Sencha Conference 2011 next week in Austin, TX. Sencha’s WebKit contributor, Jarred Nicholls will also be available for a presentation on Monday, October 24. In this presentation, we will explain what Hacking WebKit & Its JavaScript Engines is all about. Basically, it is about how your browser works and how you can use WebKit to assist your rich web apps development. Below is an excerpt from the official abstract
WebKit, along with its JavaScript engines, is not a magical black box. We will show you the internal of various WebKit building blocks (10,000-foot overview) and how they work together. In particular, learn also the simple steps on how to experiment with WebKit with your own and leverage WebKit functionalities to find the performance problems, track the network issues, automate effective smoke tests, and implement per-pixel correctness tests. In addition, armed with a little extra knowledge about JavaScript engines, you will be ready to improve both the quality and performance of your JavaScript code.
Web browsers take advantage of modern GPU and Hardware Acceleration on Mobile is here to give you a detailed information on how that happens. Previously, there is a write-up on Understanding Hardware Acceleration on Mobile Browsers but this talk is much more elaborate and self-explanatory. With regards to this, the official abstract added
GPU acceleration on mobile browsers, if it is leveraged correctly, can lead to a smooth and fluid applications, thus improving the user experience. There has been a lot of mentions and best practices of hardware acceleration these days, although so far it has been pretty general and hasn’t provided much technical direction apart from simple magical advice such as “use translate3d”. This talk sheds some more light on browser interactions with the GPU and explain what happens behind the scenes, covering the topic of acceleration of primitive drawing, the use of tiled backing store, and composited layer. Knowing the actual machinery behind hardware acceleration, you will be in the position to plan your strategy to improve the performance of your web application.
If by any means you pass through Austin and are interested in this talk, just drop by and enjoy yourself.
