  • Welcome to ubiquitous file sharing (December 08, 2009)

    - by user12612012
    The core of any file server is its file system and ZFS provides the foundation on which we have built our ubiquitous file sharing and single access control model.  ZFS has a rich, Windows and NFSv4 compatible, ACL implementation (ZFS only uses ACLs), it understands both UNIX IDs and Windows SIDs and it is integrated with the identity mapping service; it knows when a UNIX/NIS user and a Windows user are equivalent, and similarly for groups.  We have a single access control architecture, regardless of whether you are accessing the system via NFS or SMB/CIFS.The NFS and SMB protocol services are also integrated with the identity mapping service and shares are not restricted to UNIX permissions or Windows permissions.  All access control is performed by ZFS, the system can always share file systems simultaneously over both protocols and our model is native access to any share from either protocol.Modal architectures have unnecessary restrictions, confusing rules, administrative overhead and weird deployments to try to make them work; they exist as a compromise not because they offer a benefit.  Having some shares that only support UNIX permissions, others that only support ACLs and some that support both in a quirky way really doesn't seem like the sort of thing you'd want in a multi-protocol file server.  Perhaps because the server has been built on a file system that was designed for UNIX permissions, possibly with ACL support bolted on as an add-on afterthought, or because the protocol services are not truly integrated with the operating system, it may not be capable of supporting a single integrated model.With a single, integrated sharing and access control model: If you connect from Windows or another SMB/CIFS client: The system creates a credential containing both your Windows identity and your UNIX/NIS identity.  The credential includes UNIX/NIS IDs and SIDs, and UNIX/NIS groups and Windows groups. If your Windows identity is mapped to an ephemeral ID, files created by you will be owned by your Windows identity (ZFS understands both UNIX IDs and Windows SIDs). If your Windows identity is mapped to a real UNIX/NIS UID, files created by you will be owned by your UNIX/NIS identity. If you access a file that you previously created from UNIX, the system will map your UNIX identity to your Windows identity and recognize that you are the owner.  Identity mapping also supports access checking if you are being assessed for access via the ACL. If you connect via NFS (typically from a UNIX client): The system creates a credential containing your UNIX/NIS identity (including groups). Files you create will be owned by your UNIX/NIS identity. If you access a file that you previously created from Windows and the file is owned by your UID, no mapping is required. Otherwise the system will map your Windows identity to your UNIX/NIS identity and recognize that you are the owner.  Again, mapping is fully supported during ACL processing. The NFS, SMB/CIFS and ZFS services all work cooperatively to ensure that your UNIX identity and your Windows identity are equivalent when you access the system.  This, along with the single ACL-based access control implementation, results in a system that provides that elusive ubiquitous file sharing experience.

  • Why can't gif images copy at a reasonable speed on this dell laptop with XP?

    - by alt234
    I've got this somewhat old Dell Latitude D810. Strangest thing... If I try to copy anything that has gif files in it the gif files take forever. Like a few minutes per gif regardless of size. Everything else copies fine. I notice this when copying files off our network, copying off multiple external drives, and even when files are copying during an installation process. I'm on Windows XP Pro service pack 3. I've never seen anything like this before. Anyone else?

  • PowerPivot FILTER condition optimizations

    - by Marco Russo (SQLBI)
    In the comments of a recent post from Alberto Ferrari there was an interesting note about different performance related to the order of conditions in a FILTER call. I investigated about that and Jeffrey Wang has been so nice to give me some info about actual implementation that I can share on a blog post. First of all, an important disclaimer: PowerPivot is intended to make life easier, not requiring the user to think how to write the order of elements in a formula just to get better performance....(read more)

  • Windows XP screen chopped off

    - by msindle
    Ok this one has be confused as all get out! One of the teachers at the school I support has a dell latitude e5500 and the desktop shows about 3/4 just fine, but the right 1/4th shows whatever was on the last (like its not refreshing (yes I tried refreshing the screen)) For example if I open up internet explorer then minimize it the left 3/4ths minimizes, but the right 1/4th stays pulled up. Another interesting piece of information is that if I change it to God awful 800x600 it works perfectly fine. The sceen works together and has no problems.... The only way I have found to get rid of this is to reload the laptop and that is getting old quick! Thanks for your help! Msindle

  • What is the fastest CPU my laptop can support?

    - by Dave
    I have a Dell Latitude D830 laptop and would like to speed up compile times on it. I have confirmed that it is, indeed, the processor time that is the bottleneck. How can I tell what processors are compatible with the motherboard to pick the best available? I run dual boot Ubuntu Maverick and Windows 7. lshw tells me that my motherboard is OHN338 from Dell, Inc. If anyone has a generic solution, i.e. "For motherboard X, here is how you find out what processors are supported," that would be make this question much more useful to future visitors. But if you also know of a way to find out specific to my model, that would be great as well.

  • Windows 7 Skype shifts audio to speakers

    - by Greg Reynolds
    I have noticed a strange feature on my Dell Latitude running Windows 7 and Skype. When I am listening to music on the headphones, and Skype rings, then the audio I was listening to is redirected to the computer speakers, while Skype takes over the headphones. This is infuriating as my co-workers are treated to 1 second snippets of whatever rubbish I have on at the time. Any ideas on how to stop this happening? I messed with some of the settings on Skype, but nothing seems to make any difference.

  • SPARC Architecture 2011

    - by Darryl Gove
    With what appears to be minimal fanfare, an update of the SPARC Architecture has been released. If you ever look at SPARC disassembly code, then this is the document that you need to bookmark. If you are not familiar with it, then it basically describes how a SPARC processor should behave - it doesn't describe a particular implementation, just the "generic" processor. As with all revisions, it supercedes the SPARC v9 book published back in the 90s, having both corrections, and definitions of new instructions. Anyway, should be an interesting read

  • Is this paragraph in Code Complete 2 backwards, or am I misunderstanding it?

    - by user828584
    In chapter 13, when talking about pointers, there is a paragraph: Sometimes, however, you would like to have the semantics of pass by reference—that is, that the passed object should not be altered—with the implementation of pass by value—that is, passing the actual object rather than a copy. It seems like the author made a mistake and mixed the two up. Is this true, or am I not understanding what he's saying correctly?

  • How were some language communities (eg, Ruby and Python) able to prevent fragmentation while others (eg, Lisp or ML) were not?

    - by chrisaycock
    The term "Lisp" (or "Lisp-like") is an umbrella for lots of different languages, such as Common Lisp, Scheme, and Arc. There is similar fragmentation is other language communities, like in ML. However, Ruby and Python have both managed to avoid this fate, where innovation occurred more on the implementation (like PyPy or YARV) instead of making changes to the language itself. Did the Ruby and Python communities do something special to prevent language fragmentation?

  • Can anyone explain segmented sieve of eratosthenes [on hold]

    - by Utkarsh
    I've searched all over the web on implementation of segmented sieve of eratosthenes. But I found none of them suitable for a beginner. Can anyone explain me the underlying principle behind this method? EDIT: I know that in Sieve of Eratosthenes, we find all primes upto the square root of given number and cross out all multiples of them till the given number. But what do we exactly do in its segmented version?

  • Brain Teaser: How Did I Do This (Part 1: The Solution)

    - by Geertjan
    In Part 1: The Challenge, published this time last week, I introduced a "brain teaser". The brain teaser asks you to figure out how to allow images and other files to be meaningfully dropped onto a NetBeans Platform application, i.e., on the drop something useful should happen with the dropped file: if the file is an image, the image should open in the IDE; if the file is a PDF document, the PDF viewer should open externally; if the file is a text file, it should open as a text in the IDE, etc. Solution. And here is the solution: http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/ExternalDropHandler.html When an implementation of the "ExternalDropHandler" class is available in the global Lookup, and an object is being dragged over some part of the main window, the window system may call the methods of this class to decide whether it can accept or reject the drag operation. And when the object is actually dropped, this class will be asked to handle the drop. OK, so go ahead and implement the above class and put it into the Lookup. Or... guess what? The NetBeans Platform has a default implementation of the above class, appropriately named "DefaultExternalDropHandler". Not only is this useful to learn about how to implement the ExternalDropHandler class (i.e., by reading the source here): you can simply include the module that contains this class in your own NetBeans Platform application and then your application will be able to receive external drag/drop events and do something meaningful with them thanks to the DefaultExternalDropHandler. Do this: Open your NetBeans Platform application in NetBeans IDE. Right-click the application in the Projects window and choose Properties. In the Libraries tab, expand the "ide" cluster, and select "User Utilities". (That's where "DefaultExternalDropHandler.java" is found and registered in the Lookup.) Now click the "Resolve" button, if it appears, because some additional related modules need to now be included, if they haven't been included yet. Again in the "ide" cluster in the Libraries tab, select "Image". That's the Image Editor. Click OK. Run the application. Drag an image or some other type of file into your application, from outside the application, and you'll see the application tries to handle the drop. If the file being dragged is an image, it will open in the Image Editor, which you included in the previous step of these instructions. Hurray, you're done. Without any programming at all, you've added a cool new feature to your application.

  • Windows7 + Dell D830 = frequent blue screens

    - by Mulone
    I'm using Windows 7 on a Dell laptop (Latitude D380). The laptop used to be incredibly stable on Windows XP, but now I experience frequent blue screens (with a message saying "MEMORY DUMP") when I open a lot of applications concurrently. Is there a way to diagnose the issue and track it down? It could be some incompatible drivers or application. I checked the folder C:\Windows\Minidump and I found some files. THen I tried to open them and they disappeared. Any hints?

  • HTML5 - check if font has loaded

    - by espais
    At present I load my font for my game in with @font-face For instance: @font-face { font-family: 'Orbitron'; src: url('res/orbitron-medium.ttf'); } and then reference it throughout my JS implementation as such: ctx.font = "12pt Orbitron"; where ctx is my 2d context from the canvas. However, I notice a certain lag time while the font is downloaded to the user. Is there a way I can use a default font until it is loaded in?

  • An Introduction to ASP.NET MVC Extensibility

    Because ASP.NET MVC has been designed with extensibility as its design principle; almost every logical step of the processing pipeline can be replaced with your own implementation. In fact, the best way to develop applications with ASP.NET MVC is to extend the system, Simone starts a series that explains how to implement extensions to ASP.NET MVC, starting with the ones at the beginning of the pipeline (routing extensions) and finishing with the view extensions points.
