Dart 1.5 makes it easier to develop for the mobile web. It’s important for web experiences to work great on mobile devices.
New Asynchronous APIs for Dart. The latest Dart SDK now provides a cohesive API for asynchronous programming.
Some of the new or improved classes in this release include Stream, a sequence of asynchronous events, and Future, a single asynchronous result. The Stream class is new and delivers on a common developer request for a more unified approach to events. An event can be any Dart object, which makes Streams very flexible. Consumers of a Stream can listen for events, and streams can be piped, transformed, filtered, and more. We are working to apply them across HTML, I/O, isolates, and more. Query('#button').onClick.listen((e) => submitForm()); Here is an example of streaming the contents of a file. The Future class, which represents a single value available in the future, was cleaned up and is much easier to use. Some of these changes are not backwards compatible. Over the following months we will continue to work on the libraries, applying the new asynchronous models. Dart Tips: Short Video Tutorials about Dart. Sometimes, you only have 5 minutes.
40' video sur Dart, Google “evil plot to make it easier for you to build web apps.” Google, the company whose code of conduct begins with the words “Don’t be evil,” has uploaded a new video to its developer channel talking about its programming language Dart, which Google calls its “evil plot to make it easier for you to build web apps.”
The first video is from the session: Dart – A Modern Web Language. Here’s the video’s description: The two creators of Dart will discuss the rationale behind Dart’s design and its impact on web scalability and performance. They’ll also present how Dart helps developers innovate by increasing their productivity without breaking backwards compatibility. The second is from the session: Migrating Code from GWT to Dart.

With App Engine, you can build web applications using the Go Programming Language. Your Go application runs on Google's scalable infrastructure and uses large-scale persistent storage and services. Introduction App Engine builds and executes Go application code using a safe "sandboxed" environment. Your app receives web requests, performs work, and sends responses by interacting with this environment. The Go SDK provides an interface similar to the standard Go http package; writing Go App Engine apps is akin to writing stand-alone Go web servers. The Go Programming Language.
