'Shared Source' .NET Overview

Lisa writes: "As part of Microsoft's Shared Source initiative, the company announced Tuesday the public availability of more than 1 million lines of Windows and Microsoft .NET source code--aimed primarily at universities. I guess Microsoft hopes to slow down academic support for the open-source Linux OS. Don't know why they expect this to work, but Brian Jepson has a nice overview of this shared source release."

Close the Italics!!!

Please close the italics tag! ;)

Merely an example

[jquirke]

From the Microsoft website:

Developers interested in the internal workings of the .NET Framework can explore this implementation of the CLI to see how garbage collection works, JIT compilation and verification is handled, security protocols implemented, and the organization of frameworks and virtual object systems.

and

The Shared Source CLI goes beyond the printed specification of the ECMA standards, providing a working implementation for CLI developers to explore and understand. It will be of interest to academics and researchers wishing to teach and explore modern programming language concepts, and to .NET developers interested in how the technology works.

Before people criticize Microsoft for whatever reason, and claim that this was done in Microsoft's best interest, then you are absolutely right. Microsoft, will, ultimately benefit most from this release, but so will the community.

I guess Microsoft hopes to slow down academic support for the open-source Linux OS.

How so? What is it about this release that suggests anything to "compete" at all with Linux?

Exactly what I was going to say, but you beat me too it.

The SAMBA people have already had trouble in this area and advise ppl not to look at any of MS's shared-source code. What worries me is that shared source will be presented as 'example' code to be worked on in universities, and an entire generation of programmers will be forced to study it or not graduate. That's one hell of a wedge they can use against any Windows-interoperability OSS project.

They warn about the "tainting"on the web page:

One of the key considerations that went into the design of the Rotor's shared source license is that a programmer should be able to look at the Rotor source without becoming tainted. Indeed, one of Microsoft's goals for Rotor is to be a guide for anyone who implements the ECMA CLI whether for an open source or proprietary project. Nevertheless, it will be some time before open source project organizers have had a chance to form an opinion about the Rotor's shared source license. So, if you are an active contributor to a project that overlaps with Rotor, you should check with the project organizers before looking at the source code.

FSF General Counsel's Opinion

Eben Moglen, General Counsel to the Free Software Foundation, told the DotGNU project that programmers will not be tainted [oreillynet.com] by reading the source, so long as they don't copy any of the code.

Re:Poisoning the mindspace

[Dr. Cfire]

There is only one reason microsoft eould want students to learn there source code. Windows is a virus of the mind, they will never be able to program anything half decent after viewing this code. I will have to refer to a quote about another fine microsoft product. It is practically impossible to teach good programming style to students that [sic] have had prior exposure to BASIC; as potential programmers they are mentally mutilated beyond hope of regeneration. -- Dijkstra

Actually...

[Daftspaniel]

Microsoft have released source code for years. For example the MFC Class library has the source provided with Visual Studio which helps for debugging.

This might be fun, but

[Perdo]

There is always a but... Soap keeps crashing off my desktop. I can look but not edit. I guess they are just doing what we do, ask for help when our programs are buggy and need the help of the community.

But frankly, if Microsoft needs my help, they better ask with their dollars.

Why are you supporting the Great /. blackout? Have you really thought it through???

problems with oreilly site

[abdulla]

i can't seem to view that page with konqueror (kde 2.2.1), hope you can fix that :)

Don't look or you'll be tainted!

"One of the key considerations that went into the design of the Rotor's shared source license is that a programmer should be able to look at the Rotor source without becoming tainted."

So much for that particular conspiracy theory.

Slow down Linux?

[pedershk]

Excuse me for asking - but I have to disagree with the author here. What does this have to do with trying to slow down the Linux OS?

The source code [microsoft.com] that Microsoft has released (as Shared Source [microsoft.com]) is source code for the common language runtime and quite a few of the .Net framework libraries, as well as a version of the C# compiler.

This really has nothing to do with the MS/Linux "battle" (which really doesn't exist anyway, in my opinion - at least not officially).
