Yeah, yeah. I'm the Sammy Guy. I've spent a lot of time thinking about client side tooling and frameworks and building some sizable apps. I have come to the conclusion that they all suck. Maybe even one step further - frameworks in general are not always the correct solution for your problem. That doesn't, however, mean that they're irrelevant. It just means that its not so cut and dry, one is not really better than the other, they all present tradeoffs and all have their strong points. I'll talk in general about why you shouldn't use a client side framework like Sammy or Backbone or Sproutcore or Cappucino and also why you should. These sound like opposites and like I'll be doing a lot of contradicting myself, but thats the whole point! Don't believe the hype, know the facts about framework development and make your choice and stick to it.

PDFs are traditionally rendered using native code plugins. Often enough those native code viewers turn into unintentional native code execution platforms. I will talk about Mozilla's new PDF.js pure JavaScript PDF render. Flashy demos aside I will in particular focus on performance tricks we use to make rendering fast (we just-in-time compiler PDF content!), and report on limits of the canvas API, and how we plan to fix those since we conveniently also make a popular browser: Firefox. Have you heard of it?

Using jsPerf correctly

jsPerf makes it easy to create performance test cases and run benchmarks across different browsers and devices -- but it also makes it very easy to do it wrong. Incorrect test cases lead to incorrect results, and we don't want to spread misinformation when it comes to JavaScript performance. In this presentation, we will be taking a look at some common mistakes in jsPerf tests, and we'll learn how to avoid them for great justice.

Emscripten is an open source LLVM to JavaScript compiler. It lets you take code written in C or C++ and run it on the web. It can also be used to compile entire language runtimes, like CPython, letting you run code in those languages on the web as well.

Currently a major focus of work in Emscripten is connecting with 'normal' JavaScript code. In other words, making it easy to compile some existing C++ library, then use it from your handwritten JavaScript on the web.
