'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

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?

Actually...

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

Re:Poisoning the mindspace

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.

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.

FSF General Counsel's Opinion

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

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 that Microsoft has released (as Shared Source) 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).
