An anonymous reader writes "Seth Ladd has an excellent write-up of Dart: 'When Dart was originally launched, many developers mistook it for some sort of Java clone. In truth, Dart is inspired by a range of languages such as Smalltalk, Strongtalk, Erlang, C#, and JavaScript. Get past the semicolons and curly braces, and you'll see a terse language without ceremony. ... Dart understands that sometimes you just don’t feel like appeasing a ceremonial type checker. Dart’s inclusion of an optional type system means you can use type annotations when you want, or use dynamic when that’s easier. For example, you can explore a new idea without having to first think about type hierarchies. Just experiment and use var for your types. Once the idea is tested and you’re comfortable with the design, you can add type annotations."

Today at a press conference leading up to E3, Microsoft unveiled its next-gen games/entertainment console, the Xbox One. Their stated goal for the Xbox One is to have a single device provide "all of your entertainment." One of the big changes is increased support for voice and and gesture input. You can turn the console on by voice, and it will recognize you and automatically login. Swiping to the side with your hand will browse through menu pages, and saying "Watch TV" will bring up the TV app very quickly. The same with music, internet, and movies. The new console also supports multitasking — for example, while watching a movie, you can bring up your web browser in a side panel and surf the web at the same time. There is also a built-in TV listings app that responds to channel names — saying "Watch CBS" will switch to CBS without giving it an actual channel number. By this point, you're probably asking: does it play games? Yes. Hardware specs: 8-core CPU/GPU, 8GB RAM, a Blu-ray drive, a 500GB HDD, USB 3.0, and Wi-fi Direct. (They didn't provide the CPU frequency, instead saying it had 5 billion transistors.) The Kinect sensor got an upgrade: 2Gbps of data capture has finer skeletal visibility, can detect minor orientation changes in hands and fingers, and can even calculate your balance and weight distribution. The new controller looks slightly bigger, and is designed to play well with Kinect. They've also updated Smartglass, the remote control software that runs on mobile devices, but they didn't explain much about it. The new Xbox Live will have 300,000 servers powering it, up from 15,000 this year — though, of course, no details were provided about server specs. The console will have native game capture and editing tools — essentially, a game DVR. Saved games will be stored in the cloud, and they have new matchmaking capabilities that operate in the background. Update: 05/21 17:50 GMT by S : Halo is getting its own live-action TV show, for some reason. They'll be collaborating with Steven Spielberg. Microsoft is also partnering with the NFL for live broadcasts and interactive experiences, such as split-screen Skype chats and fantasy league updates. Xbox One will be out "later this year." No price information. it will not be backward-compatible with Xbox 360 games.
