  • SQL SERVER – Relationship with Parallelism with Locks and Query Wait – Question for You

    - by Pinal Dave
    Today, I have one very simple question based on following image. A full disclaimer is that I have no idea why it is like that. I tried to reach out to few of my friends who know a lot about SQL Server but no one has any answer. Here is the question: If you go to server properties and click on Advanced you will see the following screen. Under the Parallelism section if you noticed there are four options: Cost Threshold for Parallelism Locks Max Degree of Parallelism Query Wait I can clearly understand why Cost Threshold for Parallelism and Max Degree of Parallelism belongs to Parallelism but I am not sure why we have two other options Locks and Query Wait belongs to Parallelism section. I can see that the options are ordered alphabetically but I do not understand the reason for locks and query wait to list under Parallelism. Here is the question for you – Why Locks and Query Wait options are listed under Parallelism section in SQL Server Advanced Properties? Please leave a comment with your explanation. I will publish valid answers on this blog with due credit.

  • How to get Windows 7 logon wallpaper to tile to other monitors?

    - by Oskar Duveborn
    In 2000/XP/Vista it was easy to set a wallpaper for the logon screen, either manually through tools like Logonstudio or simple registry changes by hand on prepared installation images or through custom group policies. In Windows 7 all this works as usual, but the secondary (or any additional) monitor is just black. The mouse pointer is visible on it but no matter what settings I can't get the wallpaper to tile (or stretch or fill or whatever) over onto it. This makes it hard to OEM/company brand the installation for multi-monitor users. More annoying is the fact that it looks officially supported to brand the logon wallpaper in Windows 7 - as it's made extremely easy... apart from this little catch.

  • Computer POST's and draws the BIOS screens very slowly - Motherboard issue?

    - by Ssvarc
    I have a desktop that refuses to boot into Windows. I used Hitachi DFT and the HD came back OK. I then used Memtest86+ and it took hours for the test to run. After 8+ hours it was up to test number 6. I aborted and ran Memtest86. It ran at basically the same speed. I aborted and went to look at the BIOS settings. The computer is running slow at POST. It takes a long time for the keyboard to be recognized, etc. The BIOS settings takes time to be (slowly) drawn on the screen. What could be causing such behavior? EDIT: I gave back the computer a while back without ever discovering the cause so I'm closing the question.

  • Missing autochk program during boot

    - by a sandwhich
    I just resized a windows partition which involved shifting about 160GB to the left. After that it couldn't find the boot like normal so I ran the system repair tool like normal(I resize this partition a lot and each time I have to use the repair disk). But, this time, when I rebooted into the recovered 7 partition, it displayed the windows logo like normal but then flashed up autochk program not found -- skipping autocheck After that being on the screen for about 8 seconds, there was a flash of a bluescreen with white text and it rebooted. I have tried running the repair disk multiple times, but it returns and fixes the same problem each time, and the same thing happens on boot each time. Is there anything I can do to fix this short of reinstalling Windows? I have also ran two chkdsks from my vista partition with no errors reported and when viewing all the files on the drive everything seems to be in place.

  • Role of systems in entity systems architecture

    - by bio595
    I've been reading a lot about entity components and systems and have thought that the idea of an entity just being an ID is quite interesting. However I don't know how this completely works with the components aspect or the systems aspect. A component is just a data object managed by some relevant system. A collision system uses some BoundsComponent together with a spatial data structure to determine if collisions have happened. All good so far, but what if multiple systems need access to the same component? Where should the data live? An input system could modify an entities BoundsComponent, but the physics system(s) need access to the same component as does some rendering system. Also, how are entities constructed? One of the advantages I've read so much about is flexibility in entity construction. Are systems intrinsically tied to a component? If I want to introduce some new component, do I also have to introduce a new system or modify an existing one? Another thing that I've read often is that the 'type' of an entity is inferred by what components it has. If my entity is just an id how can I know that my robot entity needs to be moved or rendered and thus modified by some system? Sorry for the long post (or at least it seems so from my phone screen)!

  • off-the-shelf HDD in Dell Optiplex 755 - Invalid Replacement - Press F1 when rebooting

    - by Eric Liprandi
    I recently put an SSD into my work Optiplex 755. Since then, every time the system boots or reboots, I get prompted to hit F1 to continue with a message like HDD replacement is not valid. The system works just fine. What I am gathering from Dell's website is that I left the original drive internally as a data drive. And apparently the Optiplex does not support 2 drives in the configuration we purchased originally and complains. Any suggestions on how to get rid of this message? some suggested the MEBx or whatever from Intel and to turn it off, but I did not succeed earlier. It's not a big deal 80% of the time, but I regularly work from home and occasionally need to fire a reboot and well, you don't get the BIOS screen remotely :) Regards, Eric.

  • 1080p playback on external monitor

    - by xibalban
    My system (netbook) specs: 1.6 GHz dual core atom N2600 2 GB DDR3 RAM Integrated GMA3600 GPU Win 7 Professional 32 Bit Daum Pot Player V-1.5 The issue: I downloaded a 1.33 GB sized 1920 x 1080 HD documentary (file extension: mp4) and it plays without a hitch using pot player. However, when I connected an external display (an LED Full HD 24" monitor) using D-Sub, the video plays fine but the player controls become very unresponsive. For instance, it takes about 40 seconds to exit full screen while playing. I tried: Installed/updated all the latest monitor drivers Updated the VGA drivers for GMA3600 No other programs ran while the video played, with most unwanted services and background processes disabled/killed. CPU usage goes only up to 49% when the video plays Question: What may I do in order to improve the player response/video playback experience? Do I need to play with (or change) Pot Player's default video decoders, etc?

    - by qwerty2
    Hi all, Pulling my hair out here. I recently replaced my D: 1TB drive (not a system drive) with a new 1.5TB drive. I loaded Windows XP, formatted the new drive and it was showing as working fine, alongside my C: windows system drive. I restart my machine and all of a sudden, Windows doesn't load and instead I get: "Windows could not start beause the following file is missing or corrupt" \WINDOWS\SYSTEM32\CONFIG\SYSTEM I don't have the original XP installation CD, although I do have another copy of XP, when I try and boot to it, I get the blue 'STOP' screen after it attempts to load the setup utlity for about a minute. Can someone please help? When I set up my new hard drive as a primary partition did this someone screw up my C: hard drive? Did it perhaps unmount it somehow? Any help would be fantastic. Thanks

  • Keyboard doesn't load in windows xp after Alureon infection

    - by alureonissue
    AVAST detected alureon in a number of system files including atapi.sys and kbdclass.sys iple I quarantined those files, and restarted my machine. After restarting, my keyboard and cdrom did not work (I assumed those drivers would be automatically replaced, but was apparently wrong.) I went into device manager, and checked for hardware changes, it fixed the cdrom (which works now) and looked as though it fixed the keyboard as well. It did not. After multiple reboots the keyboard is still not recognized. It works up until the XP login screen loads, after which it is completely unresponsive. Any advice would be appreciated. Thanks :)

  • Formatting minified jQuery, JavaScript using the Internet Explorer 9 Developer Toolbar

    - by Harish Ranganathan
    Much has been talked about the F12 developer toolbar in IE and the support it provides for web developers.  Starting IE8, the Developer Toolbar is a menu item that helps you view the page source, scripts, profiling and many other details of the rendered page.  It even allows script debugging from within and that makes it a truly powerful web developer tool bar. With IE9, the developer toolbar got even better with the Networking Tab that allows you to inspect the traffic/time taken and drill down into the Request/Response headers and other specifics. The script tab allows you to view the scripts used in the page. One of the challenges of working with JavaScript / jQuery when they are minified, is that, it becomes really hard to read.  Minified JavaScript is a compression technique and also a best practice for delivering faster web pages.  However, when you would like to debug, minified JavaScript files become very hard since they aren't properly formatted.  Take the case of the above sample, which is a basic MVC 3 Web Application.  It uses the minified jQuery and modernizr files. Once we select the above scripts, the script source looks as follows:- But with the “Format JavaScript” option in the Configuration icon, Once you click on the “Format JavaScript”, you can see the formatted JavaScript as per screen below:- This makes the script readable and also easy for debugging.  Cheers !!!

  • AT&T DSL 2701HG-B Modem, port forwarding to RealVNC

    - by Paula
    Our old cable modem could easily be set up to forward an "incoming port request" to the RealVNC software. Allowing us to log into our home computer from any location. We don't see any such configuration possiblity with our new AT&T DSL 2Wire 2701HG-B modem. (And it appears to have 2 entirely different 'set up screens'. Why?) Where is the screen that allows "forward incoming request for a certain port", to a certain computer, and direct it towards RealVNC"?

  • Is it possible to interrupt or cancel the trash-delete process?

    - by pete
    I am connected to the company server, onsite not remote, which is Windows based. When, in the OS finder, I go to delete a file or directory that resides on the window-based server, the trash progress panel appears as usual. Not infrequently it will just hang there appearing to be active but no progress occurs on the progress bar. So the X is chosen to stop or cancel the process. A new panel appears, and while appearing to be active, again, just hangs there indefinitely. My lack of reputation prevents posting a screen shot - sorry. The question then is this: Is there a way via the Activity Monitor, Terminal, etc. to interrupt this deleting process in the Mac OS? Currently, I have to force shutdown and reboot to eradicate the ever-deleting panel. Finder relaunch does not solve and only eliminates the finder until I force reboot. Any assistance is appreciated. Thanks, Pete iMac, Mac OS X (10.6.8), i7-2.8ghz, 8gb ram

  • QR Codes for Files on Google Code

    - by Synetech inc.
    Hi, When you download files from Google Code now (example), in addition to the text version of the SHA1 hash, it includes a QR code of it. The device that the file was downloaded to is the one that has to hash the file. But, if it can download the file (ie, has access to the webpage), it also has access to the text version of the hash, so the QR code seems completely useless—and more work to decode when the raw text is available. How would reading the hash into a mobile phone allow you to verify the file you download to the computer? Or if you download the file to the phone, how would you use the phone to take a picture of the QR code displayed on the webpage on its own screen? Does anyone know what the point to the QR code is or how you would use it to verify the downloaded file (I don’t mean QR codes in general, but specifically in this context).

  • Windows 7 keeps changing my language(keyboard) settings

    - by Hans
    I am using Windows 7 Ultimate on a Windows network. My default settings is Danish locale, Danish keyboardlayout, but English system language. I only have Danish keyboard layout installed (in Text Services and Input Languages). However, at the login screen I can choose Danish and English, but whatever I choose Windows 7 changes system language (and keyboard layout!) to English (United States). Since this is a per-App setting I must change the language setting (language bar in the taskbar) Where can this be changed system wide and permament?

  • How accurate is "Business logic should be in a service, not in a model"?

    - by Jeroen Vannevel
    Situation Earlier this evening I gave an answer to a question on StackOverflow. The question: Editing of an existing object should be done in repository layer or in service? For example if I have a User that has debt. I want to change his debt. Should I do it in UserRepository or in service for example BuyingService by getting an object, editing it and saving it ? My answer: You should leave the responsibility of mutating an object to that same object and use the repository to retrieve this object. Example situation: class User { private int debt; // debt in cents private string name; // getters public void makePayment(int cents){ debt -= cents; } } class UserRepository { public User GetUserByName(string name){ // Get appropriate user from database } } A comment I received: Business logic should really be in a service. Not in a model. What does the internet say? So, this got me searching since I've never really (consciously) used a service layer. I started reading up on the Service Layer pattern and the Unit Of Work pattern but so far I can't say I'm convinced a service layer has to be used. Take for example this article by Martin Fowler on the anti-pattern of an Anemic Domain Model: There are objects, many named after the nouns in the domain space, and these objects are connected with the rich relationships and structure that true domain models have. The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects, making them little more than bags of getters and setters. Indeed often these models come with design rules that say that you are not to put any domain logic in the the domain objects. Instead there are a set of service objects which capture all the domain logic. These services live on top of the domain model and use the domain model for data. (...) The logic that should be in a domain object is domain logic - validations, calculations, business rules - whatever you like to call it. To me, this seemed exactly what the situation was about: I advocated the manipulation of an object's data by introducing methods inside that class that do just that. However I realize that this should be a given either way, and it probably has more to do with how these methods are invoked (using a repository). I also had the feeling that in that article (see below), a Service Layer is more considered as a façade that delegates work to the underlying model, than an actual work-intensive layer. Application Layer [his name for Service Layer]: Defines the jobs the software is supposed to do and directs the expressive domain objects to work out problems. The tasks this layer is responsible for are meaningful to the business or necessary for interaction with the application layers of other systems. This layer is kept thin. It does not contain business rules or knowledge, but only coordinates tasks and delegates work to collaborations of domain objects in the next layer down. It does not have state reflecting the business situation, but it can have state that reflects the progress of a task for the user or the program. Which is reinforced here: Service interfaces. Services expose a service interface to which all inbound messages are sent. You can think of a service interface as a façade that exposes the business logic implemented in the application (typically, logic in the business layer) to potential consumers. And here: The service layer should be devoid of any application or business logic and should focus primarily on a few concerns. It should wrap Business Layer calls, translate your Domain in a common language that your clients can understand, and handle the communication medium between server and requesting client. This is a serious contrast to other resources that talk about the Service Layer: The service layer should consist of classes with methods that are units of work with actions that belong in the same transaction. Or the second answer to a question I've already linked: At some point, your application will want some business logic. Also, you might want to validate the input to make sure that there isn't something evil or nonperforming being requested. This logic belongs in your service layer. "Solution"? Following the guidelines in this answer, I came up with the following approach that uses a Service Layer: class UserController : Controller { private UserService _userService; public UserController(UserService userService){ _userService = userService; } public ActionResult MakeHimPay(string username, int amount) { _userService.MakeHimPay(username, amount); return RedirectToAction("ShowUserOverview"); } public ActionResult ShowUserOverview() { return View(); } } class UserService { private IUserRepository _userRepository; public UserService(IUserRepository userRepository) { _userRepository = userRepository; } public void MakeHimPay(username, amount) { _userRepository.GetUserByName(username).makePayment(amount); } } class UserRepository { public User GetUserByName(string name){ // Get appropriate user from database } } class User { private int debt; // debt in cents private string name; // getters public void makePayment(int cents){ debt -= cents; } } Conclusion All together not much has changed here: code from the controller has moved to the service layer (which is a good thing, so there is an upside to this approach). However this doesn't look like it had anything to do with my original answer. I realize design patterns are guidelines, not rules set in stone to be implemented whenever possible. Yet I have not found a definitive explanation of the service layer and how it should be regarded. Is it a means to simply extract logic from the controller and put it inside a service instead? Is it supposed to form a contract between the controller and the domain? Should there be a layer between the domain and the service layer? And, last but not least: following the original comment Business logic should really be in a service. Not in a model. Is this correct? How would I introduce my business logic in a service instead of the model?

  • Experience the new Bootloader of CE7 VirtualPC BSP - Display Resolution Override

    - by Kate Moss' Open Space
    The CE 7 (aka. Windows Embedded Compact) provides many new features, a new VirtualPC is one of them and as a replacement of Device Emulator in CE 6.   The bootloader of VPC BSP utilize a new introduced framework in CE7, the BLDR (not the BIOSLOADER!) It provides many rich and advanced feature, I will introduce more detail in my future posts. Today, I am going to introduce a basic usage: setting the display resolution. One of the benefit os using the BLDR is it provides interactive user interface, no DOS enviroment required, so user can change the setting on the console. It is especially useful on VPC: if you are not using Win7, edit a file in VHD could take some effort! In the Boot menu, you can select [5] Display Settings. There are a couples of sub menu allow you to change resolution, bpp and etc. As it is very straight forward, I won't go through each option except to the Option [3] "Change Viewable Display Region". The resolution it provides depends on the BIOS (VPC is a PC compatible device), and the minimum resolution it provides is 640x480. But what if user need smaller resolution or any non-standard resolution for whatever reason, it comes the use of "Change Viewable Display Region". User can use it to create a reduced display region. e.g. 240x320 on 640x480 screen. Also you can alter the platform\virtualpc\src\boot\bldr\config.c to add a non-standard resolution (e.g. 480x272) to displayMode array. Another solution in case of you don't want to rebuilt and replace bootloader is to alter SaveVGAArgs in platform\common\src\x86\common\io\ioctl.c to overwrite cxDisplayScreen and cyDisplayScreen setting to whatever resolution you want.

  • Tell me what&rsquo;s wrong! &ndash; An XNA sample demonstrating exception handling and reporting in

    - by George Clingerman
    I’ve always enjoyed using Nick Gravelyn’s exception handling in all of my games. You’re always going to encounter those unhandled exception that your players are going to ferret out and having a method to display them rather than just crashing to the dashboard is definitely more of an elegant solution. But the other day I got to thinking…what if we could do more? What if instead of just displaying the error, we could encourage the players to send us the error. So I started playing with that an expanding upon Nick’s sample code to see what I could come up with. I got close to what I envisioned, but unfortunately there were some limitations to just what the XNA API could do. In my head I was picturing the players hitting “Send Message” and a 360 message would just be sent to the XBLIG developer. Unfortunately, you can only send messages in an XNA game to someone you’re currently in a network session with. Since I didn’t want to have a 360 server running all the time, virally connecting to players just to get error messages, I did the next best thing and just open up a 360 message and encourage them to manually enter the gamertag. Maybe someday we’ll be able to do that a little better, but this works for now. In the sample, players can hit the “A” button or key to generate in an exception. If the debugger is not attached, then the Exception message screen will be shown explaining what has happened and giving the player a chance to send a 360 message to the gamertag provided or maybe even just send an email. Nick’s code has been changed just a bit. It now accepts any PlayerIndex (no longer hard coded to just PlayerIndex.One) and it no longer uses a MessageBox to get the users selection. The code has also been modified so that it works both for the 360 and for the PC. Check out “Tell me what’s wrong!” and let me know if you have any thoughts or suggestions. I really do appreciate the feedback.

  • BlitzMax - generating 2D neon glowing line effect to png file

    - by zanlok
    Originally asked on StackOverflow, but it became tumbleweed. I'm looking to create a glowing line effect in BlitzMax, something like a Star Wars lightsaber or laserbeam. Doesn't have to be realtime, but just to TImage objects and then maybe saved to PNG for later use in animation. I'm happy to use 3D features, but it will be for use in a 2D game. Since it will be on black/space background, my strategy is to draw a series of white blurred lines with color and high transparency, then eventually central lines less blurred and more white. What I want to draw is actually bezier curved lines. Drawing curved lines is easy enough, but I can't use the technique above to create a good laser/neon effect because it comes out looking very segmented. So, I think it may be better to use a blur effect/shader on what does render well, which is a 1-pixel bezier curve. The problems I've been having are: Applying a shader to just a certain area of the screen where lines are drawn. If there's a way to do draw lines to a texture and then blur that texture and save the png, that would be great to hear about. There's got to be a way to do this, but I just haven't gotten the right elements working together yet. Any help from someone familiar with this stuff would be greatly appreciated. Using just 2D calls could be advantageous, simpler to understand and re-use. It would be very nice to know how to save a PNG that preserves the transparency/alpha stuff. p.s. I've reviewed this post (and many many others on the Blitz site), have samples working, and even developed my own 5x5 frag shaders. But, it's 3D and a scene-wide thing that doesn't seem to convert to 2D or just a certain area very well. I'd rather understand how to apply shading to a 2D scene, especially using the specifics of BlitzMax.

    I have a Macbook that has unfortunately died on me. I randomly got a pop up message that said I needed to restart my computer, and once I did, I was greeted with the blinking folder question mark start up screen. I've tried everything, including running Disk Utility repair and reformatting the hard drive and reinstalling OS X. All of my data is backed up and safe, I just need my computer to start again. Before I go off and buy a new hard drive, I wanted to see if there is anything I might have forgotten.

  • How to turn off the unity launch bar in ubuntu 11.10

    - by user22106
    I would like to use the unity option in ubuntu but without the unity sidebar. I've seen how I can select to use just gnome from the login screen but there are some things I like about the unity interface. E.g. From what I've seen I like the integrated application menu with the ubuntu menu up the top that unity option comes with. So I really just want to turn the launch bar off. Any help would be appreciated. Cheers, Ben

  • Google Chrome app file opened is not always in front, receiving focus

    - by Philipp Lenssen
    On Windows Vista, I'm launching files associated with a Google Chrome "Application Shortcut" app by double-clicking them. While they will always open this way, they will sometimes not receive focus -- i.e. they sit in the task bar quietly but don't actually show in front on the screen (until I click on the app in the task bar again). Does anyone know how I can force the just-opened app to receive focus? The app being opened actually contains a web app I can customize, so I also have access to performing JavaScript commands post-startup. For background information, here is the regedit file I originally used to create the file association. Might well be this is a Google Chrome internal issue... apps I open with other editors get their focus alright, AFAIK. Thanks!
