The release notes will tell you more.

Wow. "One crazy idea that the team had at that dinner was to translate Android's source code to C#. Android would benefit from C# performance features like structures, P/Invoke, real generics and our more mature runtime. We decided it was crazy enough to try. So we started a small skunkworks project with the goal of doing a machine translation of Android from Java to C#. We called this project XobotOS." Most of Android's layouts and controls are now in C#. The small benchmark is stunning, but as much as I admire the work, I'm wondering that this like going from bad to worse - from Oracle's Java to Microsoft's C#.

Two weeks ago we covered the news that the Mono development team were let go kicked out by the new owners of Novel, Attachmate, apparently to move operations to Germany. Miguel de Icazza, founder of Mono, has taken this opportunity to break off on his own and has started a new company, Xamarin, to bring commercial .NET development products to iOS and Android.

"The Mono Project releases the first preview of Moonlight 3.0, giving application developers a first look at the open-source implementation of Microsoft's Silverlight 3 technology for the Linux platform." Sadly, it's still Firefox-only.

The Mono project has released Moonlight 2, the open source implementation of Microsoft's Silverlight. Moonlight allows Silverlight content to run on platforms that do not have an official Silverlight client, such as Linux and PowerPC Macs. Microsoft also expanded its patent agreement with Novell to cover all users of Moonlight, no matter the Linux version.

If you don't like personal, blog-style reporting, you might want to skip this item. A few days ago, during a speech at Software Freedom Day in Boston, Richard Stallman has, at least in my book, crossed a line that I thought he would never cross.

As you would have guessed, the Mono debate is long from over. Two weeks ago, Microsoft extended its legally binding and perpetual community promise to cover the C# and CLI ECMA standards, which was generally seen as a good thing for Linux-centric fans of the C# language as well as for the Mono project. The FSF has responded now, and it isn't too impressed with Microsoft's move.

We've already seen some heavy discussion on Mono and C# here on OSAlert the past few weeks, as it became clear the patent situation regarding the ECMA parts of Mono was anything but faith inspiring. This issue seems to be resolved now: Microsoft has made a legally binding promise not to sue anyone who uses or distributes implementations of said ECMA standards. Following this news, Mono will be split in two; the ECMA standard parts, and the rest.

We've had a lot of debates recently on the merits - or dangers - of Mono. We've had troubles with how Microsoft views Mono and whether or not everyone is safe using it, but we also had a public back-and-forth among Debian maintainers. During all this, Richard Stallman remained pretty mum on the issue, today he broke the silence on the FSF website.

If there is one technology in the Linux world that ruffles feathers whenever it's mentioned, it's Mono, the open source .Net clone. Since .Net comes out of Microsoft, and has some patents encircling it, it is said to be a legal nightmare. Supposedly, you can obtain a "royalty-free, reasonable and non-discriminatory" license from Microsoft regarding the patents surrounding Mono. iTWire decided to look at just how easy (or hard) it is to get such a license. Turns out it's kind of hard.

"The Mono Migration Analyzer tool, or MoMA, helps users port Microsoft .NET programs to Mono, with the ultimate goal of porting Windows software to Linux. But is it really necessary? eWEEK Labs puts MoMA through its paces."

Novell's Miguel de Icaza has announced on his blog that Moonlight has hit the 1.0 milestone. Moonlight is the open source implementation of Microsoft's Silverlight technology, a framework similar to Adobe's Flash. Silverlight has already been used during the Olympic Games and President Obama's inauguration for streaming those events across the internet.

The Mono Project releases version 2.2 this week with full support for SIMD extensions being one of the more interesting features (Betanews article). The extension allows SIMD code to be accelerated above and beyond the speed of past Mono and current .NET releases. Johnathan Allen from InfoQ impresses the significance of the latest Mono release in a blog entry. "It represents something bigger; Mono is outgrowing the standard. Mono is not just playing catch-up any more, it is trying to move past the CLR in many areas. And as an open source project, they can slip in new libraries at a much faster clip than Microsoft. Instead of trying to build everything themselves, they can simply pick up mature projects like Mono. Options or the collection library C5 and include them in the standard release."
