Port 25: The Open Source Community at Microsoft : Mono, Community

Apache Qpid Moves Forward

Sandy Gupta — Tue, 29 Sep 2009 11:15:00 GMT

Microsoft recently made a significant code drop to the Apache Qpid project. For those of you who don't know, Qpid is Apache's implementation of the Advanced Message Queuing Protocol (aka AMQP), which is an exciting new reliable messaging protocol developed by some of the world's biggest messaging users (think names like JPMorgan Chase).

What we've done is a Windows Communication Foundation (WCF) Channel for AMQP. Our goal is to provide a first class AMQP experience for the .NET developer. And, since this is an Apache project we're talking about, all our code is obviously open source.

A couple of years ago the announcement of Microsoft making a major contribution to an open source project would have been sensational news, but things have moved on a little bit since then. Now it's just another day's work at Microsoft.

As the manager of this effort at Microsoft, I'd like to talk a little about what we bring to the open source table. We joined the Apache Qpid project, which was essentially focused on Linux, to help the community develop a port on Windows and integration with the .NET stack.

That was reflected both in the code itself and also in the build environment it used (autotools). One of the areas where we invested was the introduction of a cross-platform build and test environment (CMake), so as to smooth the way for cross-platform work.

We have continued to adopt our typical product development quality assurance mechanisms when working with open-source. These include team-based design and code reviews. We also use automated code-quality tools, such as StyleCop, to ensure consistent style and to detect common programming errors.

We developed the initial version of the WCF Channel on a private Subversion repository and used a private bug database for logging issues and work items. Now we have made the initial drop to the community, we intend to do all revisions in the Apache repository and switch to using the community Jira-based bug tracking system.

Today we have a group of 5 engineers working with Qpid, both vendors and full-time Microsoft employees. Over time, it's our goal for many of these folks to achieve committer status on the project.To date, we've worked on the following work items:

The port of the C++ broker and client library to Windows
Introduction of the CMake-based cross-platform build and test environment
Windows Communication Foundation (WCF) Channel to provide a first class AMQP experience for the .NET developer
Improved packaging for Windows, including adding DLL support and a Windows installer
In progress: Persistence provider for Windows leveraging SQL Server and the Common Log File System (CLFS)

Starting soon:

SSL support on for the Windows client library and broker

For me, leading AMQP initiative at Microsoft has been quite a learning experience. Our collaboration with the community has been strong and we have received full support from our executives.

Here at Microsoft we understand that AMQP can become the SMTP for Messaging. This means AMQP is going to have a huge beneficial impact on all kinds of users in the years to come, and we want to help make that happen.

Helping develop the open source AMQP reference implementation at Apache Qpid as part of a broad community effort is our way of moving the AMQP ball forward. I'll have a lot more news to report about our efforts in the months to come.

MindTouch: Open Source Collaboration Built on .NET

Aaron Fulkerson — Tue, 04 Aug 2009 18:05:00 GMT

It has been a while since I last guest wrote at Port25, which is always a pleasure.

Today, I am writing about the latest MindTouch software release, codename Minneopa, which introduces three new innovative capabilities: the ability to capture and collaboratively edit video, the easy packaging of applications built on MindTouch for distribution, and the new capability to stage content.

However, if you are new to MindTouch, allow me to introduce the product. The canned statement reads as follows:

MindTouch Inc. is changing the way businesses share information, consume content, and collaborate. The company's open source platform, MindTouch 2009, combines the ease of use of a wiki with the scalability, security and integration capabilities of an enterprise portal, connecting enterprise systems, databases, web services, and Web 2.0 apps to create collaborative networks.

The gist, however, is that MindTouch offers an easy to use platform that looks a lot like a wiki, but behaves more like a portal with rapid application development capabilities. The architecture is unique and quite innovative because MindTouch is implemented in C# on .NET (or Mono) and consists of the following components:

A decoupled PHP client that provides a wiki like interface for collaboration, document management, mashups, and for creating composite and situational applications
Composition of more than 120 ReSTful web services
A web service orchestration engine
An acess control layer
An extensible HTTP message bus

To really appreciate the capabilities of MindTouch it is best to watch a demo as we' are truly defining a new category in collaboration.

This new Minneopa release of MindTouch buoy's our efforts to help those who are building collaborative networks on MindTouch. This is especially useful for developers, IT workers and business users to package their enterprise dashboards, composite applications and mashups for distribution.

For the collaborative video capabilities, we partnered with Kaltura, the developer of the world's first open source online video platform. The integration with Kaltura gives MindTouch users the built-in ability to collaborate, edit, publish and syndicate video directly within MindTouch. End users can record video and have multiple parties edit while retaining a complete version history -- all within a MindTouch page.

Download MindTouch Core, the free and open source edition that runs on Windows Server with IIS, Linux or even with a VMware virtual image, which should run in hypervisor without issue. Or download the native Windows Server version of MindTouch 2009, which is packaged in an easy to install Microsoft Installer (MSI) and supports Windows Server 2003/2008.

With the commercial edition, MindTouch 2009, users also benefit from a rich set of desktop tools, more features and a collection of adapters to popular enterprise systems and databases.

Brazilian Students Set Their Own Course

Mark Stone — Mon, 16 Mar 2009 19:05:00 GMT

I’m going to tell a story that starts in Indiana, but really it’s about Brazil.

Once upon a time “scientific computing” was nearly synonymous with “Fortran”. Today, though, just about any high level language can be used to write High Performance Computing (HPC) applications. These days that language choice also includes C#.

At Indiana University, the Open Systems Lab has pioneered work to implement Message Passing Interface (MPI) support for .Net, so that MPI applications can be written in C#. The project is MPI.Net, and you can find it on Codeplex. It is open source, about three years old, has reached a 1.0 release, and is compatible with two other important open source projects, OpenMPI and Mono. The principle developers behind the project are Andrew Lumsdaine at Indiana University and his former student, Douglas Gregor, who is now on the faculty of Rensselear Polytechnic Institute.

This is the kind of open source work that’s really exciting to see because of the way it expands choices for the developer and the end user. A C# developer should not be closed off from writing HPC applications if that’s what they want to do. And a research scientist should not have to think about whether their lab is running Linux or Windows Server. Both of these individuals are working enough layers above the operating system that somebody else’s operating system choice should not be a constraint.

So I was very excited to learn that students in Brazil at Federal University of Rio Grande do Sul were doing work on MPI, and excited to talk with them about their work. One of their projects is MPI#, also open source and also hosted on Codeplex.

MPI# builds on top of the work of MPI.Net, adding some functionality not yet present in MPI.Net. Specifically, quoting from the project description:

The goals of this project would be to build upon MPI.NET in order to complement it with the features that are missing, mainly regarding collective communication. Either they could benefit from C# native support for such communication, either they could be programmed on top of the provided MPISend/MPIRecv encapsulations. C# and .NET features such as fault tolerance or dynamicity support would be studied, in other to turn the MPI# implementation robust in large, dynamic and heterogeneous platforms.

Two of the students working on MPI# are Ismael Stangherlini and Fernando Afonso. They are graduate students in computer science, working on projects affiliated with the Brazilian Interoperability and Open Source Software Development Nucleous. When I talked to them about their work on MPI# I was curious what their communication with Indiana University had been like. Their response: they had never been in contact with Indiana University; they simply downloaded the code for MPI.Net and started working on their own.

That’s the magic of open source: that they can, in fact, just download the code on their own and start coding against it. They may make an important contribution to MPI.Net. Or their code may be entirely disregarded. Or they may move on to other projects and somebody else may or may not pick up where they left off. At this stage it’s too early to tell. But the fact that all of these scenarios are possible demonstrates why, as a methodology, open source is so nimble and adaptive. A top-down product development process, or a top-down standards development process can only execute on the innovations envisioned by the few at the top, and at the speed of the slowest decision-makers in the process. But a bottom-up open source process enables every innovation that anyone at the grass roots level can see.

Moonlight 1.0 Hits the Street

Peter Galli — Wed, 11 Feb 2009 19:42:00 GMT

Moonlight 1.0 is now available.

Moonlight is an open source project that gives Linux users access to Microsoft Silverlight content, and is available for all major Linux distributions, including openSUSE, SUSE Linux Enterprise, Fedora, Red Hat, and Ubuntu. This milestone release is part of the technical collaboration between Novell and Microsoft.

Microsoft has worked with the Moonlight team and Novell to enable interoperability between Windows and Linux platforms and extend the high-quality interactive Web and video experience for the benefit of the Linux community, said Scott Guthrie, corporate vice president of Microsoft's .NET Developer Division.

Microsoft has provided Novell with access to its test suites for Silverlight, and provides Linux end users of Moonlight with free access to the Microsoft Media Pack, a set of licensed media codecs for video and audio that bring optimized and licensed decoders to every Linux user using Moonlight. Windows Media Video (.wmv), Windows Media Audio (.wma) and MP3 files are supported through the Microsoft Media Pack.

A pre-release of Moonlight was made available on January 19, 2009 to allow Linux users to stream Barack Obama's Inauguration, and more than 20,000 Linux users downloaded Moonlight to watch that Silverlight broadcast.

"Microsoft Silverlight offers the most comprehensive and powerful solution for the creation and delivery of rich internet applications and media experiences, and is used by hundreds of thousands of developers worldwide," Guthrie said.

For his part Miguel de Icaza, the founder of the Mono project founder and vice president of Developer Platforms at Novell, said Moonlight brings the benefits of Silverlight's popular multimedia content to Linux viewers. "This first release delivers on the goal of breaking down barriers to multimedia content and creating parity in the user's viewing experience regardless of whether the user is on Windows or Linux."

Moonlight Shines on Obama's Inauguration

Peter Galli — Fri, 23 Jan 2009 06:45:00 GMT

Microsoft and Novell joined forces this week to make sure that Linux users were able to watch the Barack Obama Official Inauguration stream with Novell's Moonlight, an open source implementation of Microsoft's Silverlight 1.0.

The issue was that while the inauguration stream was fully Moonlight compatible, as the full set of Silverlight 2 codecs are in the codec pack for Moonlight, the player used managed code and the Moonlight 1 beta only supports Javascript.

The solution? Developers on Novell's Mono team sprang into action the day before the Inauguration and worked late into the night so that Linux users and those with PowerPC Macs could watch the stream with Moonlight.

This is yet another great example of how co-operation can play out to the benefit of all involved, and underscores how the advantages of the relationship between Microsoft and Novell play out in the real world.

As Ben Waggoner, the Principal Video Strategist for Silverlight, said on his blog, using managed code in the player left out Linux users of the Moonlight 1.0 beta, as well as PowerPC Mac users. "We've heard a lot of requests to add support for those platforms, and so we teamed up with the Moonlight team at Novell and they've created a Silverlight 1.0 version of the player that works great in both Moonlight and PowerPC Macs," he says.

Once the CLR/DLR is supported as part of Silverlight 2 compatibility, players like the Inauguration one will work without modification. But, that something like this could come together on such short notice is "a testament to the chops and passion of the Moonlight team and the great platform we're both implementing. I'm glad we got this chance to demonstrate how serious we are about this collaboration," he says.

For his part, Novell's Miguel de Icaza's noted on his blog that Microsoft worked late into the night to get them access to the code that was used during the inauguration so it could be tested with Moonlight.

Ars Technica also has an indepth article about how this was all turned around in a day, which is worth reading.

Two Years and Counting....

Peter Galli — Wed, 19 Nov 2008 04:16:00 GMT

It is two years this month since Microsoft and Novell struck their ground-breaking technical collaboration agreement, a move that has effectively ensured greater interoperability between Windows Server and SUSE Linux Enterprise Server.

This technical collaboration has already resulted in a number of milestones, including two new offerings announced today: the availability in the first half of 2009 of an Advanced Management Pack for SUSE Linux Enterprise for Microsoft System Center Operations Manager 2007 R2, and a free beta download of Novell's Moonlight, a rich media application.

Some analysts, vendors and enterprises have said the company that develops effective cross-platform management tools will have an advantage and strategic differentiator over its competitors who do not. Microsoft is already doing that.

The Microsoft Operations Manger 2007 Cross Platform Extensions enable the assessment and management of Windows and Linux servers from a single, unified console, eliminating the costs and complexities of having multiple management consoles. The Advanced Management Pack extends this Linux monitoring capability.

Also, given the current tough economic environment, this solution helps reduce training costs since staff only need to be trained on one management tool for both Windows and Linux environments.

Attendees at the Microsoft TechEd EMEA conference in Barcelona earlier this month got to see a technical preview of the Advanced Management Pack, whose release will coincide with that of Microsoft System Center Operations Manager 2007 R2.

A beta of Novell's Moonlight, an open source implementation of Microsoft Silverlight, will also be released going forward as an open source plug-in for the Firefox web browser. Moonlight brings Linux-based users the same high-definition media capabilities currently available for the Windows and Apple environments.

So, expect to see a lot more solutions in the next year that promote interoperability and help ease customer pain-points across their heterogeneous environments.

Open Source Highlights at Microsoft's Professional Developers Conference

hanrahat — Tue, 04 Nov 2008 17:32:00 GMT

At last week's Professional Developers Conference in Los Angeles, product previews and announcements, particularly of Windows Azure, Windows 7 and Visual Studio Team System 2010, generated a lot of buzz. Throughout the week, an important undercurrent to that story was Microsoft's engagement with the open source community and its support for open source developers.

Certainly one of the open source highlights for the week was Miguel de Icaza's presentation, "Mono and .Net." In spite of arriving on time for the session, I wound up viewing it from the second overflow room. Miguel talked about innovations on which the Mono community has focused recently, including their embedded C# compiler. His game demos of the technology were fun and amazing to watch. You can see them for yourself here.

Members of my team spent the month leading up to the conference developing three demonstrations of Windows Azure's ability to support open source developers and open source applications. We ran all three at the Open Source pedestal in the Microsoft booth and each was highlighted in a session during the conference.

One of the demos shows how developers can use Eclipse to create applications and deploy them as Azure services. It relies on an Eclipse community plug-in "Emonics" for displaying C# syntax and a "proof-of-concept" Azure plug-in we created for building and deploying the application. This demo was highlighted in Steve Marx's presentation, "Developing and Deploying Your First Cloud Service," which you can find here.

The second demo shows how an open source application can access services from Azure. In this one, we chose the popular PHP application Gallery and show how it can store, retrieve and modify photos as binary large objects (BLOBs) in the cloud. To produce this demo we wrote two small modules, one to create wrappers that represent the BLOB REST API as PHP objects and another to create an Azure subclass with inheritance from the Windows NT Platform class.

We created the third demo to illustrate how an open source developer can use OpenID to authenticate users from an Azure service. For this one, we modified a demo blog service (based on BlogEngine.net) and gave users the option of authenticating through either OpenID or Live ID.

Both the Gallery and OpenID demos were highlighted in Daniel Wang and Stefan Schackow's presentation, "Cloud Computing: Programming in the Cloud." You can find Daniel and Stefan's presentation here.

The excitement that PDC produced was remarkable. I moved through a steady stream of developers for four days, all of us sustained it seems by tables of fruit, powerbars and various forms of chocolate. I enjoyed meeting and talking with many of the attendees and as always appreciate how much I learn in those conversations.

I want to thank Steve Marx, Daniel Wang and Stefan Schackow for sharing the stage with us. Kudos to Hank Janssen, Anandeep Pannu, Garrett Serack and Joel Penner for creating the Azure demonstrations we used throughout the week. And a tip of my hat to Miguel for making the week so fun.

Silverlight on Linux

Sam Ramji — Wed, 05 Sep 2007 10:45:00 GMT

For those of you who have met Miguel de Icaza, you know right away what I mean when I say that he is one of the most energetic people I’ve ever met. Clearly, the whole Moonlight team (whom I haven’t met) would also qualify for this appellation – in roughly 21 days between May and June, they collectively built an alpha implementation of Silverlight on Linux, based on many pieces of the Mono codebase.

After a great deal of work between the Moonlight and .NET teams, we’re ready to formally announce that we (Microsoft and Novell) will be bringing Silverlight to Linux, fully supported and including application and media codec compatibility.

The expansion of the existing work between Microsoft and Novell to include support for Silverlight on all Linux platforms is a major step in the journey of interoperability that we are on. We’ve heard clearly from the community that a full cross-platform web development solution is not only Windows and Macintosh, but must include Linux. I think this is a big deal. While we’ve licensed media codecs before, this represents a fully heterogeneous implementation of a strategic client technology.

Here’s to a better web and support for all users. Hopefully this will help breed further productive conversations about what developers and users need, and in someone else’s famous words, we can all “just get along.”

Cheers,

Sam
