Moonshine

by Miguel de Icaza

Now that Moonlight 1.0 is out, I should talk a little bit about Aaron Bockover's amazing Moonshine plugin.

Moonshine's About Box while playing HBO.com

Moonshine is a tiny plugin that registers itself with Firefox to render Windows Media streams and emulates the Windows Media Javascript API by redirecting it to Moonlight.

So when you visit a page that in the past used to embed the Windows Media Player (for example at HBO.com or at C-SPAN), instead you get a Moonlight-based rendering engine and uses Microsoft's Media Pack for doing the video and audio playback.

It is trivial to install it, just go to this page and click on the moonshine that is right for your platform.

Internally we referred to this project as "Pornilus" a homage to the Roman senator and patron of the arts from the 3rd century. And like Pornilus, we want to bring the arts to the people.

Cute fact: Pornilus/Moonshine will pick-up your Gnome theme and theme itself accordingly.

Oddly enough, there is no Wikipedia page for Pornilus yet. Someone needs to correct this.

Moonlight 1.0 goes live

by Miguel de Icaza

Moonlight, the open source implementation of Silverlight for Unix systems has officially reached its 1.0 level. We are feature complete, we pass all the Microsoft regression test suites and we shipped support for Microsoft's Media Pack for x86 and x86-64 architectures.

Moonlight is available as a Firefox plugin that can be installed with a single click from the moonlight download page.

What is in Moonlight 1.0

Moonlight 1.0 contains our plugin that can be used in Firefox 2 and 3 on Unix systems using the X11 windowing system.

Moonlight 1.0 (and Silverlight 1.0) both come with a graphics pipeline, video and audio frameworks and a javascript bridge and neither one of them contains an actual execution environment. The execution environment is the browser's own Javascript engine. When developers build 1.0-based plugins they script all of the functionality using the browser's own Javascript engine.

The browser Javascript engine communicates with Silverlight (or Moonlight) through the Javascript API exposed by the plugin.

With Silverlight 2.0 and Moonlight 2.0 in addition to this model where the browser's Javascript drives the interaction a new model is available: the ECMA CLI execution system powers the actual execution of the code and will deliver performance anywhere between 20 to 300 times faster execution speed than even the most modern Javascript implementation if you use a strongly typed language like C# or Boo.

CNN's The Moment on Moonlight.

It is worth pointing out that Moonlight is provided both for 32 bit systems and 64 bit systems on the launch date.

We are also hoping to expand our reach to other Unix variants that use X11 like the various BSD systems and Solaris and make codecs available for those.

How we got here

The development of Moonlight has been a fascinating adventure. It all started at the Mix conference in May 2007 when Scott Guthrie introduced Silverlight 1.1. It was a bold move for Microsoft to embed the ECMA CLI into their Silverlight 1.0 plugin.

In my blog post called "Mix 07, Silverlight, Dynamic Languages Runtime and OpenSource". From that post you can see that I was already excited about the technology, and I could not wait to get this technology to Linux. The talk on the DLR at Mix 07 was also fascinating and got me interested in bringing this to Linux.

A few weeks after the DLR had been announced and open sourced, our team had it working on Linux with Mono and by the end of May I had cooked up enough to render a spinning video on the screen.

It was during the dynamic language workshop at Microsoft that I had a chance to have dinner with Jason Zander and Scott Guthrie in an Indian restaurant in downtown Redmond. In this dinner they discussed some of the design tradeoffs in Silverlight and these would become part of our own implementation a few days later.

At Mix 2007 I had the chance to meet Marc Jalabert from Microsoft France. Marc invited me to the Remix event in Paris but did not take the invitation seriously until he offered us to demo Moonlight on Jun 21st.

Other than a spinning video and the DLR we did not really have much code so on May 31st I sent an email to the team and asked them to work on an intense 21-day hackaton to bring Silverlight 1.1 to life on Linux. By Jun 21st we had a demo working and we showed Silverlight 1.1 applications (with the CLR) running on Linux.

A few weeks passed by, and Jeff Jaffe from Novell asked me to present our Moonlight to Bob Muglia as part of the regular Microsoft/Novell interoperability meetings. After struggling with the video projector for what seemed like an eternity the Silverlight Chess and the Silverlight Airlines demo came up on the screen on Linux.

In the meantime, we were in love with our Moonlight engine, and we used to build desktop applications in addition to web applications.

After this meeting, I do not remember exactly how things happened as too much happened too quickly, but Microsoft and Novell agreed to collaborate on bringing Silverlight to Linux. We announced the collaboration on September 5th.

It was early on, at that dinner with Jason and Scott that the issue of how to properly license codecs for MP3, WMV and VC-1 had been discussed. We knew that we could implement the engine, but the question remained: how to get codecs to end-users in a fully licensed way. This and other problems had been already discussed and agreed on the collaboration agreement. Microsoft would develop, distribute and maintain their own Media Pack for Linux users and other Unix operating systems.

The entire media work involved hard work at every level, but it was worth the effort. We now have one of the best open source media pipelines implemented. And it will only get better with all the new features in Silverlight 2 for adaptive streaming.

The Immediate Future

We are now hard at work on Moonlight 2, and those of you interested in trying it out can do so by following the build instructions on our web site.

Silverlight 2.0 was a major upgrade from its original announcement Silverlight 1.1. It is more complete, more polished and has been future-proofed.

Microsoft has continued to help us all along in creating an open source implementation of Silverlight. They have open sourced the Microsoft DLR, the Microsoft MEF framework and the crown jewels: the Microsoft Silverlight Control Library and the Control Toolkit under the OSI-approved MS-PL licenses. Without this it would have taken years for us to catch up.

Jimmy Schementi's IronRuby + DOM + Flickr sample.

Up until two weeks ago we could not see much in the screen as a lot of Moonlight had inter-dependencies between various subsystems. But once Larry Ewing's layout system landed in our tree, magically many things started to come together.

You can try out yourself Moonlight with some very hot demos including CNN's The Moment, the Photosynth-based 3D browsing engine for Obama's Inauguration and of course the always amazing DLR demostrations.

Silverlight 3

Silverlight 2 is incredibly exciting, it is delicious and mindblowing. There is a lot of excitement about it, my favorite three sites on Silverlight 2 include:

Microsoft will be announcing the details about Silverlight 3 at their Mix conference in March in Las Vegas.

My wish list

I love Silverlight and the use of the CLR for building web applications. That is just how I am wired up.

I still personally wish that Silverlight 2.0 had a JSon interface to XAML, like the prototype that Chris Toshok did, or that Silverlight had a more fluent model for application deployment. I would like the XAP model to be entirely optional or non-existent for IronRuby or IronPython.

It is that time of the Quarter! Traveling to Microsoft.

by Miguel de Icaza

When Joseph and myself head out to Redmond to meet with some folks at Microsoft about Moonlight.

This is a call for all cool cats at Microsoft that would like to get together and talk shop to drop me an email (miguel at gnome dot org) and we can schedule something.

XBox Division at Microsoft

by Miguel de Icaza

For about a year I have been trying to find someone in the XBox360 division at Microsoft that we can talk to about bringing Mono to the XBox360 to allow C/C++ developers to script their applications with the high performing C#, Boo or the Iron* languages as opposed to interpreters.

A year ago Mono could not target the XBox360 as apparently this platform, like the iPhone, does not support JITing. Mono now supports full static compilation of .NET code into native code before deployment and we would very much like to bring this to the XBox360.

If you are a Microsofty and you know how to get a hold of someone on the XBox360 group in the Middleware division and you could hook us up, I would love if you could arrange an introduction.

Linux Outlaws Podcast

by Miguel de Icaza

Last week the folks at Linux Outlaws interviewed me about Mono.

The idea was that someone on a previous episode apparently did not quite like Mono and they wanted to hear my take. In the end I am not sure that we even talked about their concerns, but it was a fun interview.

IronClad

by Miguel de Icaza

The guys at Resolver Systems have released IronClad. IronClad is a library that allows IronPython to use any existing compiled CPython extension.

The new version has matured to the point that it is able to use CPython's numpy and pass its test suite.

It is lovely to see third parties start to test their code with Mono in addition to .NET as part of the release process. The code has been tested with Mono, and comes with Unix makefiles.

DekiWiki powers WhoRunsGov.Com

by Miguel de Icaza

Aaron Fulkerson and his team at Mindtouch have done it again. This time they landed the Washington Post new http://whorunsgov.com project:

WhoRunsGov.com provides a unique look at the world of Washington through its key players and personalities. The site features concise profiles of influential political officials who shape government policy, including members of the new presidential administration, Pentagon officials, lawmakers, senior congressional aides and committee staff. The first several hundred profiles are being crafted by a newly created editorial team at the Washington Post Company, as well as a group of experienced outside contributors. Each profile provides in-depth information on an official’s policy experience, involvement in government decision-making, major policy positions, key associates, political affiliations, voting records, campaign and personal finance information, plus relevant news articles from around the Web.

Their Deki project has gone from the cutest Wiki system to a full collaboration platform.

Their press release has the details.

And as my readers have come to expect, yes, this is also built on top of Mono. Deki is not built with ASP.NET --Microsoft's web platform-- instead the engine is built on top of Mindtouch's Dream framework and the presentation layer is built on top of PHP.

Congraulations to Mindtouch on this important launch!

Cartoon Network's Kid's MMO and Mono.

by Miguel de Icaza

The amazing Joachim Ante from Unity3D wrote me to tell me that Cartoon Network's new browser-based MMO for kids FusionFall has finally launched to the public.

Fusion Fall takes advantage of many new features in Unity3D for creating large worlds. I live blogged some of the details as Joachim presented them at the Unite Conference.

Unity uses the Mono runtime on both Windows and MacOS and it might become one of the largest deployment vehicles for the Mono VM.

There is an air of coolness in the fact that Mono is being used on Windows instead of .NET. And part of it has to do with the fact that Mono's open source engine allowed Unity to modify it to suit their very specific needs.

As I mentioned at my PDC talk, the .NET engine is fantastic, but up until Mono only Microsoft was in a position to reshape .NET into different forms (Silverlight and Mesh both use a special trimmed-down .NET called CoreCLR). I would love to see a world where people take Mono (or chunks of Mono) tune it and shape it to suit their needs.

Congratulations to the team at Unity for a job well done, and to the team that produced FusionFall. You can see the introduction video:

One thing that stands out in FusionFall is that it shows what a big creative budget can do with Unity.

Go Mono gaming, Go!
