Finally HTML5 matches and beats Native

Finally HTML5 matches and beats Native (Steve Newcomb)

Achieving consistent and predictable HTML5 Application performance in mobile devices is a function of properly managing the complex interaction between the DOM, events, image handling and data handling combined with an intricate knowledge of how to avoid the deficiencies within Webkit and other rendering engines. The more complex your code, the more complex your interactions and thus the more complex it becomes to solve for performance.

This session will give you the lessons learned from’ two year journey where they went from duck taping hell to finally returning to proper engineering and once again enjoying their jobs. This talk will help you avoid their mistakes and hopefully arm you with tools, rendering engine knowledge and coding techniques to tame your hornet’s nest.

The following topics will be covered in this session:

  • How the WebCore rendering engine works
  • Touch gestures in 2D and 3D rendered environments
  • DOM rendering vs Canvas vs WebGL
  • Understanding composite layer rendering to the GPU
  • Understanding Matrix3D transforms
  • Challenging CSS3 primitive performance
  • Appending WebCore with a Javascript render engine

About Steve Newcomb:

@stevenewcomb is perhaps best known for being the founder of the Peter Thiel funded Powerset which was the world’s first large scale semantic search engine. Powerset was acquired by Microsoft and is now part of the Bing search engine. But perhaps his most important accomplishment was the 72 engineers he hired at Powerset, known as the Powerset Mafia - many of whom now hold key roles in the largest tech companies in the Valley and have founded a host of successful startups including GitHub, Serious Business and Crowdflower. Steve is also well known for an essay he wrote called "Cult Creation" - a definitive essay on the importance of building a cult around engineering as a culture and way of life. It has been read by more than a million people, is used as part of many startups’ HR programs and is taught as part of the curriculum at UC Berkeley’s Engineering School. For the last two years Steve has been heads down building a new team and working on a front end framework for building HTML5 apps called He generally does not like human beings, but seems to have an affinity towards the plight of javascript engineers and interaction designers. If you are an MBA student and know nothing at all about engineering, any interaction you choose to have with him will be at your own risk.

    Does anybody have the list of the 50 more things where CSS3 can ruin your performance. I remember during Steve's presentation, he was showing a few examples. I'm curious to know what's on the entire list.

      I think you are referring to this slide: http://www.slideshare...­ ? The last few pages of the deck include several links on the topic as well.
