Marek Safar reports on the progress on the C# 3.0 compiler front:

This week:

Finished 3.0 type inference.

Next Week:

Review and finish the implementation of collection initializers and anonymous types. They are the only remaining bits to have all LINQ components ready for the integration.

Pretty much all the C# 3.0 features are now completed. As Marek points out there are a couple of areas that still need some work (collection initializers and anonymous types), but we are in good shape to complete the LINQ support in Mono's C# compiler.

JB Evain has also been busy creating a new profile of our compiler for developing Silverlight applications. The new command is smcs and it differs from gmcs in the following ways:

• It enables -langversion:linq by default (so C# 3.0 is the default in the Silverlight profile).
• Generates assemblies that reference the 2.1.0.0 mscorlib (as opposed to 2.0 that gmcs does).
• It references by default all the Silverlight assemblies. With mcs and gmcs we only reference System and System.XML by default. We felt that in the case of Silverlight we could reference all the libraries needed by default.

The majority of our C# 3.0 support will be available in Mono 1.2.5. The recent developments (type inference) did not make it into the release, so folks will have to wait for 1.2.6.

Last year we had a pretty fun meeting in Boston, but there were a few problems: the event was too short, and renting the hotel was too expensive and we also announced it with very little time ahead.

We want to do another Mono Summit and we would like to do this event in Spain if possible. The reason is that it is relatively easy to reach Spain and for the European Mono developers (the majority of the Mono team is European) it would be cheaper to fly there than to fly to the US. Spain is also a bit cheaper than other destinations.

I would like to find a University that could host us for a week of talks, meetings and conferences of the Mono community.

We would need space for about 120-150 people: maybe some conference rooms for a couple of talks, otherwise classrooms and a place to hack, discuss and some internet connection would be all that we need. This would be sometime in October.

My preference would be for Madrid or Barcelona as they both are well connected by international air travel.

Anyone out there interested in hosting us?

As I was reading this morning Twenty-Five Ways To Suppress Truth: The Rules of Disinformation I was pointed to about Groklaw's latest attempt to defy gravity.

As it is becoming common in some circles, some folks like to be purer than the virgin Mary. Groklaw has been for a while expanding into new levels of fundamentalism. The ends justify the means and all that:

That, to me, wasn't the news, since a Microsoft license was submitted once before, although I gather not by the company. But what I'm noticing is reactions. ComputerWorld collected some truly astonishing responses, and if you follow their links, it gets worse. First, though, the reaction that matters, from Michael Tiemann:

Michael Tiemann, president of the non-profit Open Source Initiative, said that provisions in three out of five of Microsoft's shared-source licenses that restrict source code to running only on the Windows operating system would contravene a fundamental tenet of open-source licenses as laid out by the OSI. By those rules, code must be free for anyone to view, use, modify as they see fit.

"I am certain that if they say Windows-only machines, that would not fly because that would restrict the field of use," said Tiemann in an interview late Friday.

Why would this need to be said? What nerve Microsoft has to even dream of trying for such a restriction. A license that restricts use to only the Windows operating system. Why would OSI even consider that? Have we lost our minds?

Groklaw: Another Smooth Move from Microsoft: Watch out, Ruby. Watch out OSI.

Really?

4. Use a straw man. Find or create a seeming element of your opponent's argument which you can easily knock down to make yourself look good and the opponent to look bad. Either make up an issue you may safely imply exists based on your interpretation of the opponent/opponent arguments/situation, or select the weakest aspect of the weakest charges. Amplify their significance and destroy them in a way which appears to debunk all the charges, real and fabricated alike, while actually avoiding discussion of the real issues.

The Rules of Disinformation

Microsoft has a number of licenses under the "Shared Source" umbrella. Most of them are completely useless from an open source standpoint. Michael Tiemann correctly points that out and they would fail the test.

The only license that can be submitted for OSI approval is the Microsoft Permissive License (Ms-PL) and possibly the Microsoft Community License (Ms-CL). The former is an Apache-like license, the latter is a GPL-like license. Am personally only interested in the first as that is what IronPython, IronRuby, the Dynamic Language Runtime and the ASP.NET client library are licensed under.

Groklaw goes on to rally up the troops over *other* licenses that are not even under discussion. You would think that this was so obvious that it did not need pointing out, but I guess it needs pointing out.

Later Groklaw seems confused: how a company can have software open sourced but not embrace it as an open source?

And does Microsoft want to be an Open Source company? Puh-lease. They may want you to think that, but Steve Ballmer just told the world that it can't embrace that model:

"Open source has been the issue that surrounds us. Could a commercial model like Microsoft compete with open source? And we've worked very hard on making the value of a commercial company surpass what the open-source community can deliver, because frankly, it's not a business model we can embrace. It's inconsistent with shareholder value."

Does it get any clearer? And if they have no intention of adopting that business model, the right question is: why are they proposing open source licenses?

There is no contradiction here. It is only contradictory if you live in a binary world world of black and white. Or if you find images like this to be magic:

You can open source pieces of software, contribute to open source projects and still not embrace open source as your business model. It is easy to prove this by way of existing examples. Consider IBM and Google: they use open source software, they contribute to open source projects and they fund open source development, but yet their business model is not an open source model.

An ugly trend is the adoption of the absolutist mindsets. "You are with us or you are against us". Well, for one, am not with Groklaw and am not with Microsoft. My goal is to make open source succeed as a platform and use open source for all of my server and desktop activities. I see no problem in taking open source contribution from companies that have not embraced open source as their business model as long as the code is open source. So I will happily consume open source code produced by Google, IBM and even Microsoft.

Groklaw asks:

By the way, guys, check those license submissions carefully. Do they exclude the GPL? Do they exclude sublicensing or allow it only if the sublicensee contacts Microsoft to get permission? How about if a licensee sells the company?

Well, you would think they would have read the license, but it is easier to get on a rage binge than actually reading the licenses. There is no exclusion for the GPL or Copy-left licenses, the only problem is that the GPL is incompatible with pretty much anything, so chances are these will be incompatible altough am no lawyer and I do not know for sure; They do not exclude sublicensing and you do not need permission from Microsoft, nor do you need to contact them if you sell the company.

The rage binge continues:

In that connection, I suggest you look very, very carefully at the IronRuby initiative. The first rule with Microsoft proposals has to be: look for the devilish part. It won't be obvious. Here's the license for it, Microsoft's Permissive Licence, one of the shared source licenses. Is it Open Source?

The MsPL seems to satisfy both the open source definition and the Debian Free Software Guidelines.

Groklaw questions IronRuby motives and in the best conspiracy theory tone ponders:

Is that the only question we should be asking? Here's another. Is IronRuby Ruby? [...] Ruby with a Microsoft twist.

Obviously they do not know much about IronPython and IronRuby and the trouble they went to in IronPython to remain compatible with CPython. The troubles they went into to be compatible have been explained numerous times, but they are also available on Jim's Zen of the DLR slide deck. I removed the OpenXML remarks as they were just more pandering.

The article continues by mixing half-facts and speculation as it is now a tradition over there:

In Ruby's case, my understanding is that it started as Ruby.NET under the MIT license.

It has different goals, IronRuby is layered on top of the DLR. They got permission to reuse the parser and tokenizer from Ruby.NET which had done all the leg-work of figuring it out (since Ruby does not have a formal language specification).

The half facts continue:

Microsoft has added some WPF functions to it. WPF stands for Windows Presentation Foundation. Some would tell you that WPF threatens an open web, the W3c standards, and basically anything involved with the open Internet. I don't know, not being a programmer, but that's what I hear.

I will agree that you do not know what you are talking about. IronRuby can call any CLI methods and classes just like Ruby.NET and IronPython can (or, gasp, CPython extensions can do so as well) . WPF being just a collection of .NET classes they can be invoked by IronRuby.

Being able to call CLI code is why I can write IronRuby applications that use Gtk# today on Linux without any changes to IronRuby, there is no magic needed:

IronRuby Alpha running on Linux/x86 with Mono, calling Gtk#.

LOOKOUT! ITS SPIDER PIG! MICROSOFT'S SECRET PLOT TO OVERTAKE THE INTERNETS BY ADDING GTK# SUPPORT TO IRONRUBY!

Oh wait. Does that means that libraries are an evil plot as well? Tune in next week at the same bat-time on the same bat-channel for an answer.

Then, Groklaw tries a little of guilt by association, always a fine choice in the most reputable sophistry circles:

For me, it's enough of a warning that Miguel likes the MPL as he did the patent deal and all things Microsoft. He says the license is "by all intents and purposes an open source license". Whose intents? And whose purposes? Remember Lily Tomlin's old joke? If love is the answer, can you rephrase the question? And if this is "by all intents and purposes an open source license" then maybe it's time to look at that definition again.

Facts and legal terms mean nothing. If Miguel likes it, it must be bad. I hope Groklaw gets nominated for "Best use of Fallacies to Advance a Political Cause" award next year.

So if the license were to fit the open source definition then "it's time to look at the definition again". Why? Well, because Groklaw said so. Not because "they know" as we already know that they barely researched the subject.

Now am off to get some more work done on Moonlight, which will serve two purposes: allow Linux users to access Silverlight content and produce an ulcer on Groklaw's posters.

Disclaimers

And as usual to avoid the usual round trip in the comments:

• I speak for myself, I do not speak for Novell;
• This blog entry does not represents the views of my employer.
• I do not like Microsoft's overall business model, I do not like the pricing, I do not like lock-in into proprietary standards, do not like their patent threats, nor do I endorse FUD (theirs or anyone else's).
• Liking MsPL does not mean "endorsing Microsoft" wholeheartedly.
• I have been asking for collaboration between Microsoft and the open source community for years, and advocating it with their employees and representatives at every turn in the past. Most recently, before I even knew about the Microsoft/Novell agreement am on the record calling for such a thing.

I think that we have reached a sorry state when our community has to resort to half-truths pandering with fear, uncertainty and doubt. The very actions that people criticize Microsoft for. We can do better than that.

Last week or so an article that described some ugly scenes in Iraq was published, the article was written by an American soldier in Iraq under a pseudonym.

Since the picture painted was not very rosy, war supporters set out to discredit the article and its author. The author eventually had to come out and now the war supporters are launching a campaign to punish him.

Blogger Jon Swift has collected the twisted logic and hillarious conclusions in a phenomenal post.

You could not ask for a better radiography of cognitive dissonance.

On the Topic of Serving in Iraq, oh, and the anti-Christ.

Continuing with the previous topic, Max Blumenthal from the Nation has a great video: Generation Chickenhawk: The Unauthorized College Republican National Convention Tour:

Max goes on to ask College Republicans why they have not enlisted to serve in Iraq, the answers are pure gold.

These are good news, as reported on the O'Reilly Radar by Tim:

In his keynote at OSCON, Microsoft General Manager of Platform Strategy Bill Hilf announced that Microsoft is submitting its shared source licenses to the Open Source Initiative. This is a huge, long-awaited move. It will be earthshaking for both Microsoft and for the open source community if the licenses are in fact certified as open source licenses. Microsoft has been releasing a lot of software as shared source (nearly 650 projects, according to Bill). If this is suddenly certified as true open source software, it will be a lot harder to draw a bright line between Microsoft and the open source community.

Bill also announced that Microsoft has created a new top level link at microsoft.com, microsoft.com/opensource to bring together in one place all Microsoft's open source efforts. Bill sees this as the culmination of a long process of making open source a legitimate part of Microsoft's strategy. Open source has survived Microsoft's process of "software darwinism" and is becoming an ever more important part of its thinking.

Bill understands open source.

As I said last year on Microsoft's Port25, in my opinion, part of the reaction that Microsoft had towards Linux and open source had its roots in the way it was portrayed as a Microsoft killer. Anything that is portrayed as a killer of something will be less than welcome. Or like they say out there, you attract more bees with honey than with vinegar.

Open sourcing software is a great step for Microsoft. I hope that they continue on this path of openness, and I hope that they will have a good experience with external collaborations with the software projects that they are opening up to external contributors.

In the last year Microsoft moved away from merely opening up source code under open source terms to actually creating communities that would co-develop components with them. This is the case with their AjaxToolkit for ASP.NET AJAX (Mono-plug: soon in a Linux server near you).

With IronRuby and its class libraries they will be taking new steps again. These will be the the first projects in which the software is not only open source, but where they will taking contributions back into it.

Update: In the comments to the piece, Tim has some interesting things to say, and I agree with them:

Ultimately, I believe this is significant because I believe that Microsoft realizes that they are on the losing side of history. Year by year, they have come closer to recognizing that the old models are dead, and that new ones need to be explored.

This doesn't mean that all their software will be open source. But I don't see people abusing Chris DiBona about Google's open source program because all of Google's software isn't open source either. And IBM gets lots of love for eclipse and other open source moves without being castigated for all the things they (still) do on the other side of the ledger.

You guys seem like the Shiites and Sunni in Iraq. No, the other side isn't to be trusted. But the consequence of not trusting, and escalating hostilities, is far worse than exploring what trust is offered, and building on it.

If you care about Microsoft becoming more free and open, support the people at Microsoft who are trying to bring them along.

This other piece is right on track:

Demonizing the other side (in business or in war) is an easy way of actually ignoring the actual facts, after all its easy to say that the devil is bad:

Dalibor -- my reference to "you guys" was specifically to all the people saying Microsoft is innately bad. All I can say is that if you believe that, you've never spent much time with folks at Microsoft. It's easy to demonize someone you don't know. Harder when you actually talk with them. There are some people there (including the top leadership) that I don't trust, but there are a lot of people trying to make positive change. Help them, don't hate them.

As to the "losing side of history", my thinking is shaped profoundly by my study of the history of the IBM PC, which broke IBM's old stranglehold on the industry via proprietary hardware. That change didn't make IBM go away, but they had to change to survive, and now everyone thinks they are a good guy.

I predict a very similar outcome for Microsoft. Free and open source software have changed the world, but not in the way we expected. It doesn't mean that "free" triumphs, just that the locus of proprietary value capture and protection changes from software to something else, just as it previously changed from hardware to software.

I've written about these ideas at length in The Open Source Paradigm Shift and What is Web 2.0, and events since I wrote those pieces have only confirmed my view.

I completely agree that Microsoft is participating where they find it useful ... but so is IBM, and Sun, and Google, and Oracle, and even Red Hat, Canonical, MySQL and other "open source" companies. It's never just black and white.

I could not agree more.

Republican candidates have been busy crying wolf in the past set of presidential debates. They have gotten their share of softball question on the issue ("if a bomb is about to go off and kill a million people and you had a chance to stop it, would you?") but they barely discuss anything that actually matters.

John Lam at Microsoft has released the first preview of IronRuby: a Ruby compiler that targets the .NET framework (licensed under the MS-Pl license, which is by all intents and purposes an open source license).

The source code is here. Seo Sanghyeon has already put together a kit to build and run it on Linux with Mono. There is one downside, you will need Mono from SVN, as you need the same fixes for Mono that were required to run IronPython 2.0 and Dynamic Language Runtime (DLR).

Congratulations to the DLR team at Microsoft for this release. They have also been working towards opening up the development process to external contributors:

We're also happy to announce that we will be accepting source code contributions into the IronRuby libraries. Right now we have a lot of logistical work that we still need to do, but we fully intend on getting IronRuby onto Rubyforge by the end of August.

Some of you may be wondering why we are only accepting contributions into the libraries and not the entire compiler. It's because IronRuby is built on top of the Dynamic Language Runtime (DLR), and the public interfaces to the DLR are not complete at this time. Since the DLR will ship as part of the CLR in the future, we cannot accept contributions into the IronRuby compiler, at least initially. However, once the DLR matures and reaches 1.0 status with fully supported public interfaces, we will fully open up all parts of the IronRuby project for external contributions.

It is worth noting that the future home of IronRuby wont be CodePlex but RubyForge, John said:

I (and I'll use I here since I fully take responsibility for this decision if it doesn't work) felt that more folks contributing to open source projects were comfortable with Subversion than with TFS. I wanted to make it as easy as possible for folks to contribute, so Rubyforge was the natural choice here.

This is a probably a good time to point to Joel Reed's work. He wrote an open source client for accessing TFS systems (CodePlex or your own company's server) from Unix systems running Mono.

Value Types and Null, the mistery continues

You will notice a patch in Seo's distribution. This patch is necessary because until today I had refused to implement this broken behavior of CSC 2.0 in Mono's C# compiler.

Today I finally gave up the resistance and implemented it in version 82517. But I must point out that so far there is no good explanation as to why this broken behavior is present in CSC in the first place. A few months ago I posted the question on this blog and we had a lively discussion but never found a satisfactory answer to this behavior.
