Nah he probably does what one of my Dad's friends did which was installed a shower into his London apartment although he already had a shower in the bath.  However he used the bath for brewing beer and ale.

Heres some stats from the "World" build on my little old Pentium D with 2gig of RAM: nib: CPU time consumed by jobs : 00:54:12.8906250 nib: in user mode : 00:52:55.0312500 nib: in kernel mode : 00:01:17.8593750 nib: Elapsed time (wall time) : 00:27:54.0888391 nib: nib: Parallel throughput ratio: 194% nib: 153 job(s) succeeded, 0 job(s) failed Unfortunatly being at work right now I wont be able to run it until I get home tonight X( Oh actually it outputted an ISO image I can use in VirtualPC .... sweet

"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.

You have found the source at last!!! ;P BTW We got two more OS in C# Cosmos[^] and SharpOS[^]

Sounds a like a good idea (slurp!) :beer:

Thanks for your your superfical opinion :P Why don't you spend time reading all the avalible information about it and actually have a look at it rather than just cherry picking a couple of statements and throwing in an uninformed opinion?

You are welcome. Dont forget, I've got lots of opinions. If you dont like them, I've got plenty more!

Because it wouldnt be so ammusing? No, seriously though, I am up to my neck in splenulous regurgitant over the amount of cack that Microsoft comes out with and I am really sure this is just more of the same given the brief description YOU linked to. If you have a better link, then perhaps I will take a look but I doubt I will be convinced that it is sufficiently different or velid to get excited about. Look at COM. My god people had their pants down over that and now look at it? Its dead, finished, useless, replaced. Why? Because it was just more cack that served no purpose at all.

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.

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?

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 :)

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 );

Yeah, eventually people give up trying to reinvent the wheel and be clever and end up writing in C, or C++ at a push. (Actually, they are the same language anyway)

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.

C# is not an interpreted language (in general, there do exist C# inerpreters, but nobody uses them).

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.

Looks like they've stolen a few ideas from COBOL 99[^], particularly the read-ahead, precompile thing.
