Mono Beta 2 Released
A little birdy writes "Less than a month after Beta 1 was released,
Mono Beta 2 has been released. See the Release Notes, or go directly to the download page. It includes a C# compiler, an implementation of the Common Language Infrastructure and two stacks of APIs: a Unix, Linux, GNOME, Mono stack for APIs that takes the most advantage of your Unix server and desktop and a set of APIs compatible with the Microsoft .NET Framework 1.1 that provides support for ASP.NET (web services and web forms), ADO.NET and many other components." And in a related story: darthcamaro writes "The drive to develop a FOSS implementation of Microsoft's .NET framework by DotGNU and Novell's Mono project is being painted as a contest between the Free and Open Source communities in an article on internetnews.com. The article details the running argument between DotGNU's Norbert Bollow and Mono's Miguel de Icaza on the issues of commercial involvement, software patents and all the 'religious' stuff that the Free software community holds against the open source community."
Is this the same as Stereo Alpha 1?
Does anyone know of any significant applications developed using the Mono Linux API stack yet?
Also will the applications I write with this stack work on Windows?

The mono C# compiler is a work of engineering genius.
It uses a program called TreeCC which goes beyond the Lex+Yacc model and provides an aspect-oriented tree programming model. This makes it very easy to write visitor patterns on your tree, and you can do syntax and semantic analysis with ease.
The resulting source code for a full working C# compiler is minute. TreeCC expands it into the real code.
Check it out!
It will be interesting to see what the performance comparisons of MSNET/MonoNET and MonoNet/LinJava. I would also like to see the CLI for Java project gain steam to take over some MS mkt share on the Winserver side (and allow seamless upgrades to Lin/Unix for those). Since C-pound is much like a C++/Java mutant it is not hard to transfer to the language.
I'm quite interested in seeing the first tools to take advantage of System.DirectoryServices, as this should enable us to manage a windows Active Directory natively from Linux.
I agree with Bollow's reasoning and reality, but I fear that his sentiments may fall far short of his dream. He'll have to cope with
With that said, I think it's a very good idea to try to slowly nudge Microsoft developers over to other platforms, particularly if we come out with more advanced and/or convenient features than Microsoft's own standards. Nevertheless, time will tell whether this project pans out or not.
The only information that is needed for the success of mono is the following: are the relevant ECMA standards 334 and 335 and just RAND, or are they really RAND and royalty free as miguel and others have claimed?
.NET is really very nice and productive. Microsoft will finally have made a valuable and lasting contribution to computer science.
If it is really RAND and royalty free, it will become my favorite development platform. Working with
If not, it is just another poisoned fruit by microsoft.

Here's what is actually happening. When companies are deciding on .Net or other technologies, these projects are held up as examples of how choosing .Net will not lock you into Windows. Then they go ahead with buying the Windows servers and developing the half working .Net app.
He may think he's giving companies choice to move to Linux. But what he is really doing is providing justification for choosing Windows.

We do support two stacks of APIs today in Mono: the Microsoft compatible stack (ASP.NET, ADO.NET and Windows.Forms) but we have been investing heavily in taking advantage of our own set of libraries that Linux, Unix, Gnome, X, Mozilla, CORBA specific.
For instance, Microsoft uses XmlSchema, Mono supports it, but distributed RelaxNG support as well.
We are working on Windows.Forms, but we also have strong bindings for Gtk# to build native applications. In fact MonoDevelop (www.monodevelop.org) is fully written using this stack.
We support the Microsoft database APIs, but we ship providers for all the open source (Postgress, MySQL, Sqlite) providers and other third party databases (DB2, Sybase, Oracle).
Tao is a backend agnostic set of 3D graphic APIs (OpenGL, Cg, SDL) while we still plan on supporting the Direct3D managed APIs.
Our set of APIs is what has allowed us to build things like MonoDevelop: a fairly complete IDE for Mono for developing Linux-based applications.
I was under impression that mono has switched to a modern generational garbage collector, the Intel ORP GC. But the current beta uses the conservative boehm garbage collector.
A conservative GC is nice for a quick hack, but it really does not cut it for a modern VM.
So which one will it use in mono 1.0? Boehm or ORP? And if it is the boehm collector, what plans are there to switch to a modern GC?
By the way: the conservative garbage collector is the only real technical flaw of mono. Other than that it is quite a modern VM. Quite amazing for this short development time...

"I would highly recommend you actually do some research for yourself rather than forcing /.'ers to do it."
Well, quite.
RAND != Royalty Free and Non-Discriminatory
RAND == Reasonable And Non-Discriminatory
So, in fact, they *can* and *do* charge money to licence patents under RAND. RAND is not good enough for any Free Software, GPL or otherwise.

This seems like a legitimate set of concerns, but I think the ability of Microsoft to change the game at this point is severely limited.
The reason why Microsoft can't radically alter .NET is because of the existance of legacy apps. The company I work for has thousands of man-hours and hundreds of thousands of dollars into our ASP.NET applications. Microsoft can't break these applications. The .NET API has to remain consistant or they'll lose that legacy application support and lose customers. The fastest way to piss off an IT department is to make a change that breaks their apps. Believe me, I know...
So, if Mono can get the .NET 1.1 standards done, they can support all those legacy apps with few changes. Even if/when Microsoft introduces some spiffy new libraries with .NET 2.0, businesses can still say "it's cheaper for us to get off the forced upgrade wagon and move to Mono as a platform for .NET and we can keep our legacy applications." Unless .NET 2.0 comes up with some massively useful new system, there isn't that strong a reason to upgrade.
Granted, Microsoft can still pull out a patent and try to shut Mono down, which remains a threat, but I don't see them as doing that. All Mono has to do is use that as a talking point - don't develop for .NET because of patent issues. This hurts Microsoft by slowing the adoption of .NET. The worst that happens is that Mono has to fall back on its own libraries, and given that things like Gtk# are useful on their own they still have something to show for their work.
The more I think about it, the more I think Mono is in a strong position. I'd be more worried about Microsoft unleashing a patent infringement case than I would about them changing the APIs to shut out Mono. If they did that, they'd be shooting themselves in the foot.
It's as if Linux were able to run all Win95 applications just as Windows 2000 was coming around. Yes, Windows 2000 was infinitely better than 95, but if you're a PHB and you have a choice of moving your legacy apps to an expensive proprietary system or a free open one, you're going to be more inclined to do the latter as it makes your bottom line better. Legacy app support is absolutely crucial and right now Mono can do something that not even Linux can do - support Microsoft-based legacy apps with a minimum of changes. That gives Mono a big advantage in the marketplace, and while it helps Microsoft move developers to .NET it also helps make Linux a more attractive platform for enterprise development, especially on the backend.
Ive seen MonoDevelop and SharpDevelop and am not impressed with either. The day Novell is able to churn out an IDE like VS.NET for MONO is when Mono will be really able to make waves.

Yes, we are not able to fully support the
Windows.Forms API on the 1.0 timeframe (you can
get the previews, but they are not ready to ship).
Windows.Forms has a number of problems for
open source software anyways: for instance, it
does not do constraing-based layout, so for
every language that you want to support, you must
relayout your dialog boxes manually (or if you
have a larger font size).
By using Gtk# you take advantage of the Linux-specific
APIs and Linux-specific features (you can use
Gtk# on Windows, Linux and MacOS).
On the other hand, there is a community of
MacOS developers working on bindings to Cocoa
bindings to give them the same flexibility and
OS integration on the Mac.
Windows.Forms would give you a Windows-solution
everywhere.
We are going to support it for the sake of helping
Windows developers move to Unix, but it is not
a particularly great toolkit.

I would love to see an example of what this has enabled that can't be done with Microsoft's tools, even if it's just doing it for cheaper.
.5% market share.
.NET platform. The two things are pretty much completely independent. One, or the other, or both may catch on.
You can deploy your ASP.NET applications, developed with Microsoft tools, on cheap Linux server farms.
Look at the DOC format and how even slight inconsistencies can prevent other technologies from getting past
Problems with DOC compatibility are a network problem: you aren't there when the recipient's attempt to open your DOC file fails. However, even if Mono.NET isn't 100% compatible, since all the development is happening in house, you can fix it pretty easily.
If this just enhances the Linux platform or turns into a platform itself, it may have a chance.
Mono is that, too. In fact, Mono is two things: an entire environment for writing Gnome and Linux applications in C#, and an implementation of Microsoft's
Gnome desparately needs a better programming platform than C/C++, and Mono provides it.
However, once it becomes a platform, if you think MS won't try to demolish it the way it has done to every other platform, you are mistaken, especially since the project has shown no leadership and is essentially a clone of what MS is doing
Currently, Linux apps written in C/C++ are competing with Microsoft apps in C/C++, and Microsoft does whatever they do to compete. With Mono, Linux apps written in C# are competing with Microsoft apps written in C#, and Microsoft will still do whatever they do to compete, so nothing much changes.
One thing is for certain, howver: Linux apps written in C# are much more competitive with Microsoft apps written in C# than Linux apps written in C/C++. Developing apps in C/C++ is just way too much of a drag on any group of developers. Microsoft saw the light and moved on to something better, and it is high time that Linux developers do the same thing.
MONO is a very exciting concept. Having some degree of compatibility with Microsoft but with the current SCO-like strategies of litigating competition out of the picture and with the general feeling that Microsoft will use patents as a way of stifling it's biggest threat why should I feel good about the project?
Maybe someone can help me out here? What is going to prevent Microsoft from playing the patent card when it suits them?
The race isn't always to the swift... but that's the way to bet!

Although those benchmarks were done against
our first JIT. We redid our JIT to address that
(and many other issues), so the data is relatively
old (one year+)
Although the official reason that GnomeBasic was dropped was because of "stagnation", the real reason that it died was because Mono was supposed to take it's place.
If that happened, I've seen no evidence of it.
While you can write Mono code in Java, PHP, Logo, Oberon, Pascal, Forth and Lisp, VB is still unavailable.
It's a pity such a popular language appears to be entirely ignored.

Do not presume that MS's past use of patents for defensive purposes only means there is a low probability of threat to the Mono project...
MS has hired an IP manager who not only believes in but has spearheaded IP rampages.
"Marshall Phelps has long been a vocal advocate of the need for companies to take IP licensing seriously."
"...he inspired at his previous company, IBM, which is now reaping almost $2 billion a year from licensing its patents."
"At IBM we did a lot of it. We had lots of lawyers doing preparation and prosecution around the world. At Microsoft, we don't have anyone doing that, but we are going to start."
"According to Phelps, managers too often fall into the trap of seeing patents as a purely defensive measure, a tool with which to stop the competition in their tracks.
Phelps says he is pleasantly surprised by just how understanding Microsoft's executives have been. "On these IP issues I don't have much of a problem getting anyone's attention at Microsoft. It starts at the top, and if you've got a guy like Bill Gates who's really concerned about IP and really likes it then you don't have much of a management problem."
Make no mistake about it, Microsoft has learned to do business by using its capital to get what it wants. Microsoft cannot buy out FOSS but they sure as hell can litigate FOSS directly or indirectly to "stop the competition in their tracks."
As most everyone here knows, FOSS has been on the Microsoft radar for several years now and they have been very active and very unsuccessful in halting the progress of FOSS.
This is the last ditch effort on Microsoft's part to stop what is becoming an unstoppable force. It will not matter if the FOSS community produces a better and more technologically advanced product because Microsoft will not be competing based on the merit of their products.
Whether or not the patents that are filed are frivilous and ridiculous, they will be used offensively to diminish the threat of FOSS to the Microsoft revenue stream.
Be prepared, there is more of the SCO syndrome to come.
