  • Windows and Line of Business ​Application​s: No Good Options

    @blowdart: yes I know that ...

    If MS offered a 100% on premise solution to this , no reason why they couldn't, then I'd be more open to this feature. If this meant dedicated TFS server etc. so be it.

  • Windows and Line of Business ​Application​s: No Good Options

    @felix9: At the MVP summit I voiced my opposition to having the sign on into VS2013 ... I don't believe MS has the right to know such things. Infact seeing as my day job is coding, I bet my employer would want to know exactly what is shared and future roadmap of such a feature! etc.

    I can sort of understand why MS would want to do this, for syncing and making VS more personal across devices etc. BUT I still feel strongly that VS should steer clear of this authentication feature!!

  • interesting XBox Next (or Next Next) rumors that link to Drawbridge ??!!

    @felix9: you don't see how the api's are being elevated into UserMode as something similar to what Drawbridge is doing ?

  • “Why Windows is slower” - a 'rant' from within WinDiv

    No one here is talking about ... "what if windows code were open source like Linux" ... then this would be a non issue as all code would be open/visible and clearly contribution can come from anyone and fixes/changes/enhancements will rise to the top based on there own merits..

    I agree that what this so called junior, or other business unit dev did was wrong, but I also wished that MS were more open with their code bases! Would be great to see what the evolution of the kernel would be like if it were open Wink

  • Immutable collections for .NET arrive

    I would love if you could ask


    1. Why did they choose the NUGET mechanism for the ImmutableCollections feature. Is this something we should expect going forward for other features from them Smiley

    2. What made them choose using NUGET over VISUAL STUDIO EXTENSIONS.

    3. What is the next step from this preview, or more importantly how do they envision the roadmap for these NUGET delivered features...

    4. How do these features finally make there way into .NET framework?

  • Hacking Redhawk: Call Windows Class Libraries from C++

    , BitFlipper wrote

    I'm not familiar with Redhawk but I assume you mean "Reverse P/Invoke"? If so, yes the .Net framework supports being called from C. Unfortunately this functionality is not plumbed all the way through to say, C#. Ideally there should be a "DllExport" attribute that allows a .Net assembly to have that method exported and be able to be called purely from C (while initializing the .Net framework during the 1st C call).


    This is a primer to the fabled 'Redhawk'  ... its the future api of windows (or rather the base classes of windows)


    This is awesome stuff ... simply awesome!!!

  • The Singularity Project (with results)

    @evildictaitor:  I found this other document that talks about the architecture of Singularity including background information on how they came up with those cycles calculations..




    Would love your input seeing as you know this stuff intimately (assuming you have time ofcourse as its 44 pages long)  BUT its a great read Smiley



    Quote from the document

    Singularity is a micro-kernel operating system that uses advances in programming languages and compilers to build lightweight, software-isolated processes, which provide code with protection and failure isolation at lower overhead than conventional, hardware supported processes. Singularity provides an isolation boundary by running verifiably safe programs and by preventing object pointers from passing between processes' object spaces.

    SIPs, in turn, enable a new solution to the problem of code extension in systems and applications. In Singularity's model, extensions are not loaded into their parent process, but instead run in their own process and communicate over strongly typed channels. This model fixes some of the major problems with extensions, since in Singularity, they cannot directly access their parents' data or interfaces, and, if they fail, they can be easily terminated by killing their parents.

    Singularity is above all a laboratory for exploring interactions among system architecture, programming languages, compilers, specification, and verification. Advances in each of these areas enable and reinforce advances in the others domains, which limits the benefit and impact of studying an area in isolation. Singularity is small and well structured, so it is possible to make changes that span the arbitrary boundaries between these domains. At the same time, it is large and realistic enough to demonstrate the practical advantages of new techniques.


  • Joe Duffy : a "managed" system ... beat the pants off all the popular native programming environments

    Definetely sounds like evildicator knows his stuff, not questioning that. BUT I do agree with Joe Duffy as well with the overuse of split normally for massive dynamic strings and almost always with a collection of strings.. Lots of .NET devs, including myself, are very poor optimized programmers as Joe hints at..

    Regardless I also know that Joe and his team is probably working on Midori and the SingularityOS project, that several millions of lines of managed code on a managed os.

    Anyway I found some stats of Singularity, of how it improves across the board on certain OS system cycles ... Some of you may find it interesting :



  • The Singularity Project (with results)

    I found a nice Singularity paper that actually goes into some performance statistics..

    Shows across the board Cycle reductions at the OS level for many systems within the SinguarlityOS.

    I really want to see this Midori project's managed SingularityOS work (with dev platform) ... It really does sound exciting...

  • Joe Duffy : a "managed" system ... beat the pants off all the popular native programming environments

    We know that his working on a managed code base, that's several millions of lines long of managed code ... that can beat the pants off any native programming environment ...
