Admist a number of proprietary alternatives such as Adobe Flash,
Microsoft Silverlight, and Sun JavaFX, the HTML 5 specification now
offers competitive multimedia features that promises a more open
platform for RIA development. What are the tradeoffs? This session
will look at the current state of the art, and then invite a
conversation about the future.

As Android is rolled out to more new phones, and as other open source mobile operating systems surface, mobile users are beginning to enjoy many of the same freedoms as desktop users. However, even the most open smartphones are locked down to one degree or another. This talk will explore the reasons -- legal, technical, regulatory, and economic -- that a truly open phone does not yet exist.

Aside from learning Clojure's syntax and approach to functional programming and concurrency, there's also the more mundane issues: What editor do I use? How to I build large projects? How do I share my work with others? This session will discuss IDEs and plugins, command line build tools, and web sites.

Recommended for folks who are interested in languages that run in the browser as well
as the server.

A while back, it seemed that type-driven object-oriented languages such as C++ and Java had taken over. They still dominate education. Yet the last few years have seen a number of different languages reach prominence, often of very different styles: Python, Ruby, Scala, Erlang, Haskell, Lua, and many more. Surely there are enough languages. Yet new ones keep appearing. Why? And why now?

Ruby apps can now be deployed to Google App Engine thanks to JRuby. New app instances spin-up on demand so there is no need to provision hardware but each new JRuby runtime can take several seconds. Mirah (formerly Duby) is a new language with Ruby-inspired syntax that compiles directly to Java bytecode. Duby is compelling for App Engine development because new instances can spin-up in a second.

Javascript has become the universal language of the web. Usable on client or server, it can be fast, flexible, and reusable across many sites and applications.
To really master JS you need more than a framework: you need to grok some heavy-duty functional and OO concepts it took from weird languages like Scheme and Self. Come see where these ideas came from, and how to use them in your JS code.

Testing is JavaScript's Achilles' heel: the language is powerful with
good library support, but testing practices are cumbersome to
non-existent. This talk demonstrates a set of tools that make
test/behavior driven development in JavaScript as quick and effective
as Java, Ruby, or Python, including aspects unique to
JavaScript such as the browser environment and asynchronous
programming.
