Dart 1.5 makes it easier to develop for the mobile web. It’s important for web experiences to work great on mobile devices.
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.
Watch super short introductions to Dart language and library topics. Ep. 1: A Simple Dart Script Welcome to Dart Tips, the video series that teaches you all about Dart. In our first episode, we show you a simple Dart script and get you comfortable with reading Dart code. Ep. 2: Runtime Modes Dart runs fast in production mode, and runs with type assertions in checked mode. 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.” It’s a 40-minute video that talks about the programming language and its features. “When we announced Dart, it kicked up a bit of a dust storm,” says Dart engineer Bob Nystrom in the YouTube description for the video. “In this talk, I discuss the challenges that Google and others face when building web apps today.

A language for structured web programming. By Lars Bak, Software Engineer, Dart Team Cross-posted on the Chromium Blog Today we are introducing an early preview of Dart, a class-based optionally typed programming language for building web applications.
Dart’s design goals are: Create a structured yet flexible language for web programming.Make Dart feel familiar and natural to programmers and thus easy to learn.Ensure that Dart delivers high performance on all modern web browsers and environments ranging from small handheld devices to server-side execution.Dart targets a wide range of development scenarios: from a one-person project without much structure to a large-scale project needing formal types in the code to state programmer intent. To support this wide range of projects, Dart has optional types; this means you can start coding without types and add them later as needed.

Welcome to Dart, the structured web programming platform.
Go, also called golang, is a programming language initially developed at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a statically-typed language with syntax loosely derived from that of C, adding automatic memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. The language was announced in November 2009 and is now used in some of Google's production systems. Go's "gc" compiler targets the Linux, Mac OS X, FreeBSD, OpenBSD, Plan 9, and Microsoft Windows operating systems and the i386, amd64, and ARM processor architectures. A second compiler, gccgo, is a GCC frontend. Ken Thompson states that initially, Go was purely an experimental project.
Referring to himself along with the other original authors of Go, he states: When the three of us [Thompson, Rob Pike, and Robert Griesemer] got started, it was pure research.

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 runtime environment uses Go version 1.2. The SDK includes an automated build service to compile your app, so you'll never need to invoke the compiler yourself. The Go runtime environment for App Engine provides full support for goroutines, but not for parallel execution: goroutines are scheduled onto a single operating system thread.

To deploy this header site-wide for a site served with Apache, ensure that mod_headers and mod_setenvif are enabled and add the following to your httpd.conf (or appropriate configuration file): The differences between Chrome and Chrome Frame Detecting Google Chrome Frame and Prompting to Install GCF reports that it is available by extending the host's User-Agent header with the string chromeframe.
For more information see Chrome Frame User Agent. You can use server-side detection to look for this token and determine whether GCF can be used for a page. <style> /* CSS rules to use for styling the overlay: .chromeFrameOverlayContent .chromeFrameOverlayContent iframe .chromeFrameOverlayCloseBar .chromeFrameOverlayUnderlay */ </style> The document containing the script must include a body tag. You can choose how you want the user to be prompted. Once the user prompt is displayed, CFInstall examines the environment periodically to determine if the plug-in has finished installing.
