How the Scala Programming Language run internally ?
Advantage of using Scala over Java?
Scala is compiled to Java bytecode, executed by the same JVM that runs Java programs, using the same JDK class library plus a small extra Scala runtime library.
The advantages are mostly for the programmer.

Would it technically possible to write an OS kernel in Swift and assembly instead of assembly and C/C++? So I'm not asking if it would be suitable for kernel development I would like to know if it would be technically possible (as far as the computer is concerned)
Yes you can write an OS kernel in any Turing-complete language and Swift is one. How suitable your language of choice for the task is a different matter completely.

I've been trying to learn Perl, and on CPAN, I came across
Perl bindings for the libsvm Support Vector Machine library
What does bindings mean in this context?
I've never found this word before in computer science...
This kind of binding is the one that lets you use a library/API from one language (usually C, including in this case) in another language (in this case Perl).
An interface, a module that gives you access to the C library.
For example, my favorite XML parser is XML::LibXML, except it doesn't do any parsing. It's actually a glue layer that binds the objects and methods of the C++ libxml2 library to Perl objects and methods.

What's the current Scala roadmap? When are Scala 2.10 release and RC's comming?
Unfortunately I wasn't able to find any useful information on the web
This has not been made public, probably because there are no hard dates anyway, but we can expect a Scala 2.9.2, likely early this year. Scala 2.10.0 is likely to be released this year, but it's too soon to make any statements about it.
There might be a Scala 2.8.3, sort of final release for 2.8.x, like 2.7.7 is for 2.7.x.

From the Scala perspective, is there any advantage missed by using the Community version of IDEA over the Ultimate version.
I've checked the version comparison chart provided and don't really require many of the features and integrations specified. I'd be interested in things like the mentioned code coverage support, but suspect that it would be Java centric.
Coverage support is available for Scala in the Ultimate Edition. Otherwise, from the Scala perspective, functionality is the same.

what is the difference between monolithic and microkernel.
Well explained at
http://en.wikipedia.org/wiki/Microkernel ,
http://en.wikipedia.org/wiki/File:OS-structure.svg
The Wikipedia articles are pretty good. However, if you are looking for a more abstract answer, you can draw an analogy to the plugin system in Eclipse. Eclipse provides abstractions over the basic needs of an IDE and depends on plugins to implement language-specific features such as compiler integration. Similarly, a microkernel provides abstractions over low level system details and requires plugins to implement the majority of real features such as file systems and networking protocols.
