Singularity [modified]

Well since you seem to be incapable of following the links on the page I pointed at here's one of the better documents on singularity: http://research.microsoft.com/os/singularity/publications/OSR2007_RethinkingSoftwareStack.pdf[^] Singularity is only for research purposes, it's currently nothing to do with windows and won't be commercialised. It was an experiment in what can be done using modern programming practises and tools with regards to designing a new OS from the ground up. The interesting bit is the SIPs and the stuff that goes with them such as the pipelines and the fact that all code is fully verifiable.

Well something has happened that I never thought I'd see ... the source code form singularity has been released to the masses! http://www.codeplex.com/singularity[^] Here's a brief overview of the OS: http://research.microsoft.com/displayArticle.aspx?0rc=n&id=1922[^] I can't wait to get home and dive into it, I've been following this project for a few years now and I was really impressed by it, it's really caught my interest and kindled my creative juices :P

Reminds me of the time I was learning Java (late 90's) - everything was being rewritten with Java - there was JavaOS, Java Office, Java Browser (it had some other name, though), Java DBMS, you name it... The last thing of that sort was Java Desktop - which wasn't even written in Java, but in plain old C: Linux + GNOME :)

Eeek, a pdf. Hmm, perhaps not, I have to write some code for a real OS kernel, actually, for Microsoft as it happens. Anyone know a GUID to UNICODE_STRING converter?

In that C# language you so frequently disparage: Guid.ToString();//with overloads for the various formats.

Already found it thanks: NTSTATUS RtlStringFromGUID( IN REFGUID Guid, OUT PUNICODE_STRING GuidString );

Thats not what this is about ;) It's not that the developers use C# and decided to make an OS, it's that they decided to make an OS using modern tools and methodologies and C# fitted the bill. And it's not even quite that simple, they modified the language and the runtime so it fit into their ideal rather than working within the limits of what existed. It's not even a serious attempt at making something commercial, it's an experiment to try and see what things work and how things could be done better. Edit: Although that is what SharpOS is about. Thats a project that doesn't interest me so much because your right, it's best to use the right tools for the right job.

"Singularity differs fundamentally from other operating systems in that it is written almost entirely in an extension of C#," Oh my god. What a disaster. Thats going to be really slow. Of course this isnt true. The C# interpreter will be written in C of course. The middle bit sounded painfully like COM. "Singularity’s third unique architectural feature, called “manifest-based programs,” " Vista does this too, so whats new? Sounds like a load of guff to me. If you want the source code to an impressive stable OS take a look at Debian 2.6 and for ease of use, the Ubuntu derivative.

Isnt C# 'compiled' down to a p-code type level (or is it byte code a la VB). Because the C# engine will run J++ p-code so C# p-code is probably similar. So, since it isnt compiled doen to machine code, it is still interpreted no? Unless the .Net VM really can handle machine code.

Yes, C#, VB, J++, etc.. are compiled to byte-code, but when they are executed they are compiled to machine code on the fly. This is different from interpreation because interpretation doesn't execute machine code directly, and thus is very slow. All .NET apps execute as compiled machine code, they just aren't stored that way on disk.

Ah yes, of course, the JIT compiler. I suppose that once the code has been OKed by the VM it stores the compiled version for later use. Still, when you look at the assembly code generated by languages like C++ you can understand why even that isnt supported in the WIndows Kernel. God knows what C# assembly would look like, but probably worse! For me, C is for machines, for working with the HW. Its quick to write, relatively high level, but as flexible and as powerful as you could want. Of course a programmer has to be quite good to use it safely, and hence the attraction of the managed languages, relatively unskilled programmers can turn out vast amounts of reasonable product.
