MS .net vs Mono, Open Source
vinsci writes "Sometimes, reader comments to reporter-written stories are just as good as the stories themselves. Such as David Mohring's comment yesterday on ZDNet.com's story Mono & .Net: The odd couple. Since Microsoft are now using their licensing terms to stop GPL and LGPL free software, it would be a welcome sign of free software maturity at Microsoft if they actually resolved the Mono issue. The gist of his comment: 'Microsoft's CEOs have made it 'patently' clear that they intend to restrict competing .Net implementations by cultivating Microsoft's patents, [...]
Mono also implements parts of .NET that have NOT been submitted to ECMA and ISO standards. Those parts of Mono lack even the protection for IP infringement with re-implementation that ISO documentation licensing implies. [...] There [are] those that claim that .NET is open to re-implementation, but until Microsoft make a simliar public legal declaration to Sun's JSPA, any .NET re-implementation represents a pending legal mindfield.'
While on the subject of C# development, users of the GPL'd C# development environment SharpDevelop may also want to try Eclipse together with the Open Source Improve CSharp plugin for Eclipse. Eclipse also support C/C++ these days using GCC and GDB, thanks to the CDT. There are about two hundred add-on plugins available for Eclipse. Eclipse itself is available for many platforms, including Linux with native GTK 2 support."
Microsoft's strategy is to embrace, extend, and assimilate.
Isn't Mono just self assimilation? What does Microsoft have left to do if OSS just comits fratricide?
Yeah, and there was also Internet Explorer for Solaris, look how long that was supported.
And Microsoft has communicated with Miguel many times with regards to Mono
Why not communicate to the rest of the industry as to their intentions?
An interview with him on the topic is hosted on MSDN! This does not appear to be a prelude to a lawsuit.
An interview does not make a legal contract either.
Why send so much time and effort with no legal protections? All Mono has is the apparent "good will" of a company known for being overly aggressive to the point of breaking the law on occasion.
And that's not much!
Based on upvotes, Ageism is the only "-ism" Slashdotters care about and think isn't SJW
Sun's patents are much more worrisome as far as I'm concerned. For example, patent number 6,477,702, held by Sun, would seem to be infringed by any conforming Java implementation. And Sun has pulled out of every and any process that would have required them to make a declaration or commitment on patent and IP issues related to Java. Furthermore, while Sun PR likes to talk a lot about openness, I have yet to see a legally binding declaration by Sun that would guarantee that third party implementations of Java may use Sun's patents.
I don't trust Microsoft any further than I can throw the entire stack of printed MSDN documentation (which is to say, I don't trust them at all). But, all things considered, I think the risk of patent infringment claims from Microsoft over Mono are very slim indeed. All that hot air from Microsoft CEOs and Microsoft PR folks doesn't change that. Sun, on the other hand, holds known patents that could create real problems for any non-Sun Java implementation.
If you are very worried about patent problems, there is a very easy solution: don't use either Mono or Java--there are plenty of other languages a round, many of them better. If you are slightly worried about patent problems, then Mono looks like a safer choice to me than Java. And probably, you don't really have to worry about patents with either of them.
Most users' experience with swing can be summed up with the following:
1. Open any swing application
2. Right click the mouse button somewhere a context menu should appear, or click on one of the file menus.
3. Wait 3 seconds
4. Form the incorrect conclusion that Java is slow
5. Go back to using native win32 programs
Sun's been trying to "fix swing" for the last 5 years, and they've had no luck. What makes you think IBM has the magic bullet?
Swing will never be fast. The same abstractions that make it such a joy to program with make it terribly inefficiant. Print out a stack trace in a event handler function in swing and take a look at how deep it is. Every one of those functions had to be called before the event was process, and ever call had to be done through a table lookup. I'll avoid going into the whole native vs. non-native widgets debate, but forgive me if I remain skeptical about the non-native approach sun has been using with swing.
IBM (well, the company that wrote eclipse that IBM bought) did the right thing when they started from scratch to design SWT. Eclipse is amazingly responsive when compared to any swing application I've seen. Try it out yourself, I think you'll be impressed.
Really folks, patents are a problem to Free Software in every project. No Free Software project is immune to these kind of concerns as well as other complicated interactions with corporations. Look at Samba which is every bit as susceptible to MS patents as Mono. Or how about OpenGL which has problems with corporate concerns. Sun has patents on Java. At least Microsoft is bound to the ECMA patent policy which is basically RAND with required disclosure.
.NET infrastructure ie, System.Windows.Forms, ASP.NET, ADO.NET. The wine project is another area with every bit the risk that Mono faces.
Another important thing to understand is Mono isn't the only Free Software project out there that is implementing the ECMA standards. DotGNU/Portable.NET has a large par t of the ECMA specs implemented and the design goal of PNet is ECMA not the rest of MS's
So the conclusion to draw from this is: Patents are a danger to Free Software in every direction! Not just this one particular project...
