Subject: Re: Ruby and .NET

Sorry, the difference between a Ruby interpreter in Java and a Java byte
code compiler blurs. I used jPython which can compile to .class, so I
might be wrong with jRuby.


Is Java more open than .NET ? I believe so.

Cons: 

* .NET is a ECMA standard. Hmm, CLR/CLS and some libs are ECMA
standards, the biggest part of .NET is not and under MS control. How MS
controls the standard parts of .NET is not clear.

* There are other implementations of .NET (Halycon, GNUDOT, Mono). Not
really, they implement only a subset and are way behind. So you can't
port a .NET application from Windows to e.g. Linux. It's hard to go
after MS. And MS admits that there might lurk some patents in the dark
it can/will use if people do not obey.

* There is no multilanguage support fom Sun. Hmm, partly right. But
there is a JSR to support debugging multi-language byte code. MS has no
real multilanguage support in .NET either. The CLR supports all
languages that are equal to C#, other have to loose their individuality
and become C# clones (Eifel#)

Pros:
* The source code for Java is open which is sometimes very useful. 

* There are othere implementations of the JDK. 

* The JSR gives people the opportunity to define Java APIs which can
become standars and sometimes part of the standard JDKs. Sun does not
use or invent APIs without a specification and a comunity process
(compare this to hidden and frequently changing APIs from MS).
