Submission + - Microsoft releases first public preview of RTVS under MIT and GPLv2 licenses (

shutdown -p now writes: Microsoft has released the first public preview of RTVS (R Tools for Visual Studio), an extension for Visual Studio that adds support for the R (GNU S) programming language. The product is open source, and while most of the code is under the MIT license, some components are GPLv2, in accordance with the R license.

Submission + - Microsoft adds Node.js support to Visual Studio (

shutdown -p now writes: Coming from the team that had previously brought you Python Tools for Visual Studio, Microsoft has announced Node.js Tools for Visual Studio, with the release of the first public alpha. NTVS is the official extension for Visual Studio that adds support for Node.js, including editing with Intellisense, debugging, profiling, and the ability to deploy Node.js websites to Windows Azure. An overview video showcases the features, and Scott Hanselman has a detailed walkthrough.

The project is open source under Apache License 2.0. While the extension is published by Microsoft, it is a collaborative effort involving Microsoft, Red Gate (which previously had a private beta version of similar product called Visual Node), and individual contributors from the Node.js community.

Submission + - Python Tools for Visual Studio 2.0 Beta Released (

shutdown -p now writes: My team at Microsoft, which works on Python Tools for Visual Studio — a free, open source extension for Visual Studio that adds support for Python to that IDE — has just shipped a beta version of the upcoming 2.0 release with numerous new features and improvements.

PTVS supports most Python interpreters including CPython, advanced code completion, debugging, and profiling. Some highlights of this release are mixed-mode debugging of Python and C/C++ code with integrated call stacks, stepping and breakpoints; the ability to remotely attach to and debug Python programs running on Linux and OS X; and Django support with ability to conveniently deploy Django websites and services to Windows Azure.

PTVS works with Visual Studio 2010, 2012 and 2013 Preview, as well as the free Visual Studio Shell.


Submission + - Code from Microsoft submitted to jQuery (

shutdown -p now writes: Microsoft has previously announced its support for jQuery JavaScript client framework when it started bundling it with Visual Studio back in 2008. Since then, Microsoft developers, in direct cooperation with the core jQuery team and the community, have developed three new plugins — Templates, DataLink and Globalization. Today, this contribution has finally found its way upstream into the main jQuery code base, and will be included into the upcoming 1.5 release. As all other jQuery code, the plugins are dual-licensed under MIT and GPLv2, making it another rare case of Microsoft contributing code to an Open Source project under the GPL.

Submission + - Windows Phone 7 Series - Developer Perspective (

shutdown -p now writes: "As previously promised, at MIX10 developer conference, Microsoft has released details about the development side of the upcoming Windows Phone 7 Series.

It is now confirmed that two frameworks for application development will be XNA for games and game-like fullscreen, high-performance applications, and a subset of Silverlight 3 for everything else. Both frameworks support managed .NET code only — no native (C++) code support. Furthermore, the applications are sandboxed, and "unsafe" functionality, such as P/Invoke, is not available. A fairly detailed set of UI guidelines for developers has been made available as well.

The integrated web browser is claimed to be based on Internet Explorer 7 engine with some extra features, such as proper XHTML support.

An single centralized store will be available, called the Marketplace. It will include both applications and other media (such as music). The Marketplace will be the only way to install applications onto the phone (though, supposedly, "enterprise customers" will have some workaround). There will be an approval process for publishing applications on the Marketplace, and, aside from filtering out malware, it will also require that applications are "generally good taste excluding pornography, hateful/inflammatory speech, and gratuitous violence".

On the hardware side, the specifications will be tightly controlled for the benefit of developers. A standard set of hardware buttons is mandated on all phones ("Back", "Home" and "Search"). Screen size is limited to two standard resolutions: 320x480, and 480x800, and touchscreen must be capacitive, with at least 4-point multi-touch. Other requirements hardware requirements include 3D acceleration, GPS, and accelerometer.

Unlike past mobile SDK releases from Microsoft, a free version of development tools for Windows Phone will be available, named "Visual Studio 2010 Express for Windows Phone". A preview of that is presently available, complete with an emulator. In the future, a mobile-oriented version of Expression Blend 4, a designer-centric development tool, will also be available."
