• SSH Public Key - No supported authentication methods available (server sent public key)

  - by F21

  I have a 12.10 server setup in a virtual machine with its network set to bridged (essentially will be seen as a computer connected to my switch). I installed opensshd via apt-get and was able to connect to the server using putty with my username and password. I then set about trying to get it to use public/private key authentication. I did the following: Generated the keys using PuttyGen. Moved the public key to /etc/ssh/myusername/authorized_keys (I am using encrypted home directories). Set up sshd_config like so: PubkeyAuthentication yes AuthorizedKeysFile /etc/ssh/%u/authorized_keys StrictModes no PasswordAuthentication no UsePAM yes When I connect using putty or WinSCP, I get an error saying No supported authentication methods available (server sent public key). If I run sshd in debug mode, I see: PAM: initializing for "username" PAM: setting PAM_RHOST to "192.168.1.7" PAM: setting PAM_TTY to "ssh" userauth-request for user username service ssh-connection method publickey [preauth] attempt 1 failures 0 [preauth] test whether pkalg/pkblob are acceptable [preauth[ Checking blacklist file /usr/share/ssh/blacklist.RSA-1023 Checking blacklist file /etc/ssh/blacklist.RSA-1023 temporarily_use_uid: 1000/1000 (e=0/0) trying public key file /etc/ssh/username/authorized_keys fd4 clearing O_NONBLOCK restore_uid: 0/0 Failed publickey for username from 192.168.1.7 port 14343 ssh2 Received disconnect from 192.168.1.7: 14: No supported authentication methods available [preauth] do_cleanup [preauth] monitor_read_log: child log fd closed do_cleanup PAM: cleanup Why is this happening and how can I fix this?

• Unable to update the EntitySet because it has a DefiningQuery and no &lt;UpdateFunction&gt; element

  - by Harish Ranganathan

  When working with ADO.NET Entity Data Model, its often common that we generate entity schema for more than a single table from our Database.  With Entity Model generation automated with Visual Studio support, it becomes even tempting to create and work entity models to achieve an object mapping relationship. One of the errors that you might hit while trying to update an entity set either programmatically using context.SaveChanges or while using the automatic insert/update code generated by GridView etc., is “Unable to update the EntitySet <EntityName> because it has a DefiningQuery and no <UpdateFunction> element exists in the <ModificationFunctionMapping> element to support the current operation” While the description is pretty lengthy, the immediate thing that would come to our mind is to open our the entity model generated code and see if you can update it accordingly. However, the first thing to check if that, if the Entity Set is generated from a table, whether the Table defines a primary key.  Most of the times, we create tables with primary keys.  But some reference tables and tables which don’t have a primary key cannot be updated using the context of Entity and hence it would throw this error.  Unless it is a View, in which case, the default model is read-only, most of the times the above error occurs since there is no primary key defined in the table. There are other reasons why this error could popup which I am not going into for the sake of simplicity of the post.  If you find something new, please feel free to share it in comments. Hope this helps. Cheers !!!

• sshfs with fstab: connection reset by peer

  - by user171348

  I am trying to allow my laptop (Ubuntu 13.04) to access my PC (Lubuntu 13.04) hard drive through SSHFS. I'm using RSA keys to connect. It works perfectly fine if I type this in the terminal: sshfs my-PC:/a_folder /media/a_folder But I would like it to be mounted automatically when I boot my laptop. So I added myself to the fuse group: sudo adduser mynickname fuse And I added the following line to my fstab file: sshfs#mynickname@my-PC:/a_folder /media/a_folder fuse defaults,idmap=user,_netdev 0 0 When I boot the laptop, a_folder appears in the list of devices, but is not mounted. When I try to access it through Nautilus, it displays the following error: mount: only root can mount sshfs#mynickname@my-PC:/a_folder on /media/a_folder I get the same error if I try mount /media/a_folder in a terminal. If I try sudo mount /media/a_folder I get read: Connection reset by peer I tried to add "allow_other" as an option in the fstab entry, and uncommented the related line in /etc/fuse.conf, but it didn't change anything. The user "mynickname" is the owner of the folder /media/a_folder and has rwx permissions. I looked at many threads on the internet about people with quite similar issues, but nothing worked so far. Usually, people can't even do sshfs my-PC:/a_folder /media/a_folder without getting an error, whereas this works fine on my laptop. Any insight and tips will be greatly appreciated! Thanks.

• Fix Problems Upgrading Office 2010 Beta to RTM (Final) Release

  - by Mysticgeek

  There are several scenarios where you may run into trouble uninstalling the 2010 Beta and trying to install the RTM (final) release. Today we’ll cover the problems we ran into, and how to fix them. You would think upgrading from the Office 2010 Beta to the final release would be an easy process. Unfortunately, it’s not always that simple. In fact, we ran into three different scenarios where the install wasn’t smooth whatsoever. If you currently have the 2010 Beta installed, you have to remove it before you can install the RTM.  Here we’ll take a look at three different troublesome install scenarios we ran into, and how we fixed each one. Important Note: Before proceeding with any of these steps, make sure and backup your Outlook .pst files! Scenario 1 – Uninstall Office 2010 Beta & Fix Install Errors In this first scenario we have Office Professional Plus 2010 Beta 32-bit installed on a Windows 7 Home Premium 32-bit system. First try to uninstall the Office 2010 Beta by going into Control Panel and selecting Programs and Features. Scroll down to Microsoft Office Professional Plus 2010, right-click it and select Uninstall. Click Yes when the confirmation dialog box comes up. Wait while Office 2010 Beta uninstalls…the amount of time it takes will vary from system to system. To complete the uninstall process, a reboot is required. Fixing Setup Errors The problem is when you start the installation of the 2010 RTM… You get the following setup error even though you uninstalled the 2010 Beta. The problem is there are leftover Office apps or stand alone Office products. So, we need a utility that will clean them up for us.   Windows Installer Clean Up Utility Download and install the Clean Up Utility (link Below) following the defaults. After it’s installed you’ll find it in Start \ All Programs \ Windows Install Clean Up …go ahead and launch the utility. Now go through and remove all Office Programs or addins that you find in the list. Make sure you are just deleting Office apps and not something you need like Java for example. If you’re not sure what something is, doing a quick Google search should help you out. For instance we had the Office labs Ribbon Hero installed… just highlight and click Remove. Remove anything that has something to do with Office…then reboot your machine. Now, you should be able to begin the installation of Office 2010 RTM (Final) Release without any errors. If you do get an error during the install process, like this one telling us we have old version of Groove Server… Navigate to C:\Users\username\AppData\Local\Microsoft (where username is the computer name) and delete any existing MS Office folders. Then try the install again, this solved the problem in our first scenario. Scenario 2 – Not Being Able to Uninstall 2010 Beta from Programs and Features In this next scenario we have Office Professional Plus 2010 Beta 32-bit installed on a Windows 7 Home Premium 32-bit system. Another problem we ran into is not being able to uninstall the 2010 Beta from Programs and Features. When you go in to uninstall it, nothing happens. If you run into this problem, we again need to download and install the Windows Installer Clean Up Utility (link below) and manually uninstall the Beta. When you launch it, scroll down to Microsoft Office Professional Plus 2010 (Beta), highlight it and click Remove.   Click OK to the Warning Dialog box… If you see any other Office 2010, 2007, or 2003 entries you can hold the “Shift” key and highlight them all…then click Remove and click OK to the warning dialog. Now we need to delete some Registry settings. Click on Start and type regedit into the Search box and hit Enter. Navigate to HKEY_CURRENT_USER \ Software \ Microsoft \ Office and delete the folder. Then navigate to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Office and delete those keys as well. Now go into C:\Program Files and find any of these three folders…Microsoft Office, OfficeUpdate, or OfficeUpdate14…you might find one, two or all three. Either way just rename the folders with “_OLD” (without quotes) at the end. Then go into C:\Users\username\AppData\Local\Microsoft and delete any existing MS Office folders. Where in this example we have office, Office Labs, One Note…etc. Now we want to delete the contents of the Temp folder. Click on Start and type %temp% into the Search box and hit Enter. Use the key combination “Ctrl+A” to select all the files in this folder, then right-click and click Delete, or simply hit the Delete key. If you have some files that won’t delete, just skip them as they shouldn’t affect the Office install. Then empty the Recycle Bin and restart your machine. When you get back from the restart launch the Office 2010 RTM installer and you should be good to go with installation. Because we uninstalled the Office 2010 Beta manually, you may have some lingering blank icons that you’ll need to clean up. Scenario –3 Uninstall 2007 and Install 2010 32-Bit on x64 Windows 7 For this final scenario we are uninstalling Office Professional 2007 and installing Office Professional Plus 2010 32-Bit edition on a Windows Ultimate 64-bit computer. This machine actually had Office 2010 Beta 64-bit installed at one point also, it’s since been removed, and 2007 was reinstalled.  Go into Programs and Settings and uninstall Microsoft Office Professional 2007. Click Yes to the dialog box asking if you’re sure you want to uninstall it… Then wait while Office 2007 is uninstalled. The amount of time it takes will vary between systems. A restart is required to complete the process… Again we need to call upon the Windows Installer Clean Up Utility. Go through and delete any left over Office 2007 and 2010 entries. Click OK to the warning dialog that comes up. After that’s complete, navigate to HKEY_CURRENT_USER \ Software \ Microsoft \ Office and delete the folder. Then navigate to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Office and delete those keys as well. We still need to go into C:\Users\ username\AppData\ Local\ Microsoft (where username is the computer name) and delete any Office folders. In this example we have Outlook Connector, Office, and Outlook to delete. Now let’s delete the contents of the Temp folder by typing %temp% into the Search box in the Start Menu. Then delete all of the files and folders in the Temp directory. If you have some files that won’t delete, just skip them as they shouldn’t affect the Office install. Then empty the Recycle Bin and restart your machine. If you try to install the 2010 RTM at this point you might be able to begin the install, but may get the following Error 1402 message. To solve this issue, we opened the command prompt and ran the following: secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose After the command completes, kick off the Office 2010 (Final) RTM 32-bit edition. This solved the issue and Office 2010 installed successfully.   Conclusion Except for the final scenario, we found using the Windows Installer Clean Up Utility to come in very handy. Using that along with deleting a couple folders and registry settings did the trick. In the last one, we had to get a bit more geeky and use some command line magic, but it got the job done. After some extensive testing in our labs, the only time the upgrade to the RTM went smoothly was when we had a clean Vista or Windows 7 system with a fresh install of the 2010 beta only. However, chances are you went from 2003 or 2007 to the free 2010 Beta. You might also have addins or other Office products installed, so there are going to be a lot of different office files scattered throughout your PC. If that’s the case, you may run into the issues we covered here. These are a few scenarios where we got errors and were not able to install Office 2010 after removing the beta. There could be other problems, and if any of you have experienced different issues or have more good suggestions, leave a comment and let us know!

• How would the optimal Emacs-keyboard look like?

  - by Thorsten

  Emacs is a historic piece of software. It promises outstanding productivity for keyboard wizards that really want to explore it's power. The effective use of the keyboard is key to Emacs productivity, but the keyboard hardware has changed a lot since the old days, so many modern Emacs users are struggling with weird 'Emacs chords' on their Windows/IBM keyboards. If one would design a keyboard that is entirely focused on the needs of Emacs users - how would it look like? I assume the following: the standard keybindings of Emacs are accepted, redefinitions are rare exceptions we are only talking about QWERTY keyboards (including regional variations like QWERTZ) we are only considering users applying the (10 fingers) touch typing system. the question is not only about remapping the keys of existing keyboards (perfectly possible on Linux with .xmodmap and on Windows with keytweak, for example) - think about the perfect keyboard-hardware you would like to see on your desk while hacking in Emacs all day long. Please tag your answer with your locale, i.e. [en] or [de], so that everybody knows what regional layout you are using. I will answer my own question below, to show you the results of some investigation and experimentation, but I really would like to read about different approaches and their pro's and con's. The emacswiki has a somehow related page with a lot of links (http://www.emacswiki.org/emacs/RepeatedStrainInjury), but here it's about optimal keyboard design for maximal productivity, assuming avoidance of RSI as a byproduct.

• Earth’s Radiation Belt Sounds like Whale Song [Video]

  - by Jason Fitzpatrick

  The radio frequencies of Earth’s radiation belt have uncanny resemblance to a sort of whale/bird song remix. Check out this video to learn more about NASA’s efforts to explore the belts and listen to the Earth’s song. When we hear the “song” of the Earth, exactly what are we hearing? Science@NASA explains: Chorus is an electromagnetic phenomenon caused by plasma waves in Earth’s radiation belts. For years, ham radio operators on Earth have been listening to them from afar. Now, NASA’s twin Radiation Belt Storm Probes are traveling through the region of space where chorus actually comes from–and the recordings are out of this world. “This is what the radiation belts would sound like to a human being if we had radio antennas for ears,” says Kletzing, whose team at the University of Iowa built the “EMFISIS” (Electric and Magnetic Field Instrument Suite and Integrated Science) receiver used to pick up the signals. He’s careful to point out that these are not acoustic waves of the kind that travel through the air of our planet. Chorus is made of radio waves that oscillate at acoustic frequencies, between 0 and 10 kHz. The magnetic search coil antennas of the Radiation Belt Storm Probes are designed to detect these kinds of waves.

• Using RIA DomainServices with ASP.NET and MVC 2

  - by Bobby Diaz

  Recently, I started working on a new ASP.NET MVC 2 project and I wanted to reuse the data access (LINQ to SQL) and business logic methods (WCF RIA Services) that had been developed for a previous project that used Silverlight for the front-end.  I figured that I would be able to instantiate the various DomainService classes from within my controller’s action methods, because after all, the code for those services didn’t look very complicated.  WRONG!  I didn’t realize at first that some of the functionality is handled automatically by the framework when the domain services are hosted as WCF services.  After some initial searching, I came across an invaluable post by Joe McBride, which described how to get RIA Service .svc files to work in an MVC 2 Web Application, and another by Brad Abrams.  Unfortunately, Brad’s solution was for an earlier preview release of RIA Services and no longer works with the version that I am running (PDC Preview). I have not tried the RC version of WCF RIA Services, so I am not sure if any of the issues I am having have been resolved, but I wanted to come up with a way to reuse the shared libraries so I wouldn’t have to write a non-RIA version that basically did the same thing.  The classes I came up with work with the scenarios I have encountered so far, but I wanted to go ahead and post the code in case someone else is having the same trouble I had.  Hopefully this will save you a few headaches! 1. Querying When I first tried to use a DomainService class to perform a query inside one of my controller’s action methods, I got an error stating that “This DomainService has not been initialized.”  To solve this issue, I created an extension method for all DomainServices that creates the required DomainServiceContext and passes it to the service’s Initialize() method.  Here is the code for the extension method; notice that I am creating a sort of mock HttpContext for those cases when the service is running outside of IIS, such as during unit testing!     public static class ServiceExtensions     {         /// <summary>         /// Initializes the domain service by creating a new <see cref="DomainServiceContext"/>         /// and calling the base DomainService.Initialize(DomainServiceContext) method.         /// </summary>         /// <typeparam name="TService">The type of the service.</typeparam>         /// <param name="service">The service.</param>         /// <returns></returns>         public static TService Initialize<TService>(this TService service)             where TService : DomainService         {             var context = CreateDomainServiceContext();             service.Initialize(context);             return service;         }           private static DomainServiceContext CreateDomainServiceContext()         {             var provider = new ServiceProvider(new HttpContextWrapper(GetHttpContext()));             return new DomainServiceContext(provider, DomainOperationType.Query);         }           private static HttpContext GetHttpContext()         {             var context = HttpContext.Current;   #if DEBUG             // create a mock HttpContext to use during unit testing...             if ( context == null )             {                 var writer = new StringWriter();                 var request = new SimpleWorkerRequest("/", "/",                     String.Empty, String.Empty, writer);                   context = new HttpContext(request)                 {                     User = new GenericPrincipal(new GenericIdentity("debug"), null)                 };             } #endif               return context;         }     }   With that in place, I can use it almost as normally as my first attempt, except with a call to Initialize():     public ActionResult Index()     {         var service = new NorthwindService().Initialize();         var customers = service.GetCustomers();           return View(customers);     } 2. Insert / Update / Delete Once I got the records showing up, I was trying to insert new records or update existing data when I ran into the next issue.  I say issue because I wasn’t getting any kind of error, which made it a little difficult to track down.  But once I realized that that the DataContext.SubmitChanges() method gets called automatically at the end of each domain service submit operation, I could start working on a way to mimic the behavior of a hosted domain service.  What I came up with, was a base class called LinqToSqlRepository<T> that basically sits between your implementation and the default LinqToSqlDomainService<T> class.     [EnableClientAccess()]     public class NorthwindService : LinqToSqlRepository<NorthwindDataContext>     {         public IQueryable<Customer> GetCustomers()         {             return this.DataContext.Customers;         }           public void InsertCustomer(Customer customer)         {             this.DataContext.Customers.InsertOnSubmit(customer);         }           public void UpdateCustomer(Customer currentCustomer)         {             this.DataContext.Customers.TryAttach(currentCustomer,                 this.ChangeSet.GetOriginal(currentCustomer));         }           public void DeleteCustomer(Customer customer)         {             this.DataContext.Customers.TryAttach(customer);             this.DataContext.Customers.DeleteOnSubmit(customer);         }     } Notice the new base class name (just change LinqToSqlDomainService to LinqToSqlRepository).  I also added a couple of DataContext (for Table<T>) extension methods called TryAttach that will check to see if the supplied entity is already attached before attempting to attach it, which would cause an error! 3. LinqToSqlRepository<T> Below is the code for the LinqToSqlRepository class.  The comments are pretty self explanatory, but be aware of the [IgnoreOperation] attributes on the generic repository methods, which ensures that they will be ignored by the code generator and not available in the Silverlight client application.     /// <summary>     /// Provides generic repository methods on top of the standard     /// <see cref="LinqToSqlDomainService&lt;TContext&gt;"/> functionality.     /// </summary>     /// <typeparam name="TContext">The type of the context.</typeparam>     public abstract class LinqToSqlRepository<TContext> : LinqToSqlDomainService<TContext>         where TContext : System.Data.Linq.DataContext, new()     {         /// <summary>         /// Retrieves an instance of an entity using it's unique identifier.         /// </summary>         /// <typeparam name="TEntity">The type of the entity.</typeparam>         /// <param name="keyValues">The key values.</param>         /// <returns></returns>         [IgnoreOperation]         public virtual TEntity GetById<TEntity>(params object[] keyValues) where TEntity : class         {             var table = this.DataContext.GetTable<TEntity>();             var mapping = this.DataContext.Mapping.GetTable(typeof(TEntity));               var keys = mapping.RowType.IdentityMembers                 .Select((m, i) => m.Name + " = @" + i)                 .ToArray();               return table.Where(String.Join(" && ", keys), keyValues).FirstOrDefault();         }           /// <summary>         /// Creates a new query that can be executed to retrieve a collection         /// of entities from the <see cref="DataContext"/>.         /// </summary>         /// <typeparam name="TEntity">The type of the entity.</typeparam>         /// <returns></returns>         [IgnoreOperation]         public virtual IQueryable<TEntity> GetEntityQuery<TEntity>() where TEntity : class         {             return this.DataContext.GetTable<TEntity>();         }           /// <summary>         /// Inserts the specified entity.         /// </summary>         /// <typeparam name="TEntity">The type of the entity.</typeparam>         /// <param name="entity">The entity.</param>         /// <returns></returns>         [IgnoreOperation]         public virtual bool Insert<TEntity>(TEntity entity) where TEntity : class         {             //var table = this.DataContext.GetTable<TEntity>();             //table.InsertOnSubmit(entity);               return this.Submit(entity, null, DomainOperation.Insert);         }           /// <summary>         /// Updates the specified entity.         /// </summary>         /// <typeparam name="TEntity">The type of the entity.</typeparam>         /// <param name="entity">The entity.</param>         /// <returns></returns>         [IgnoreOperation]         public virtual bool Update<TEntity>(TEntity entity) where TEntity : class         {             return this.Update(entity, null);         }           /// <summary>         /// Updates the specified entity.         /// </summary>         /// <typeparam name="TEntity">The type of the entity.</typeparam>         /// <param name="entity">The entity.</param>         /// <param name="original">The original.</param>         /// <returns></returns>         [IgnoreOperation]         public virtual bool Update<TEntity>(TEntity entity, TEntity original)             where TEntity : class         {             if ( original == null )             {                 original = GetOriginal(entity);             }               var table = this.DataContext.GetTable<TEntity>();             table.TryAttach(entity, original);               return this.Submit(entity, original, DomainOperation.Update);         }           /// <summary>         /// Deletes the specified entity.         /// </summary>         /// <typeparam name="TEntity">The type of the entity.</typeparam>         /// <param name="entity">The entity.</param>         /// <returns></returns>         [IgnoreOperation]         public virtual bool Delete<TEntity>(TEntity entity) where TEntity : class         {             //var table = this.DataContext.GetTable<TEntity>();             //table.TryAttach(entity);             //table.DeleteOnSubmit(entity);               return this.Submit(entity, null, DomainOperation.Delete);         }           protected virtual bool Submit(Object entity, Object original, DomainOperation operation)         {             var entry = new ChangeSetEntry(0, entity, original, operation);             var changes = new ChangeSet(new ChangeSetEntry[] { entry });             return base.Submit(changes);         }           private TEntity GetOriginal<TEntity>(TEntity entity) where TEntity : class         {             var context = CreateDataContext();             var table = context.GetTable<TEntity>();             return table.FirstOrDefault(e => e == entity);         }     } 4. Conclusion So there you have it, a fully functional Repository implementation for your RIA Domain Services that can be consumed by your ASP.NET and MVC applications.  I have uploaded the source code along with unit tests and a sample web application that queries the Customers table from inside a Controller, as well as a Silverlight usage example. As always, I welcome any comments or suggestions on the approach I have taken.  If there is enough interest, I plan on contacting Colin Blair or maybe even the man himself, Brad Abrams, to see if this is something worthy of inclusion in the WCF RIA Services Contrib project.  What do you think? Enjoy!

• Random touchpad and keyboard freezes on new installation

  - by ancaleth

  My touchpad and keyboard freeze up on my newly installed Ubuntu 10.10. They remain frozen until you shut down manually. No keys work, cursor doesn't move - it's like a screenshot. I was using Ubuntu 10.4 via wubi before on this Laptop where this problem never occurred. (I did not migrate wubi or upgrade to 10.10, it's a fresh start. 64-bit on Dell Studio, plenty of RAM, plenty of free space on partition etc.) I can't say there is a pattern yet, once it happened during the download of packages with the Update Manager, once it was just using Firefox, no other program running. In between these crashes the laptop was booted once, updates were installed etc., firefox was used and there weren't any problems. Both crashes should be in the attached kern.log and I noticed there were some error problems before the last crash (at the end, obviously). It seems the wireless was experiencing problems. This wasn't noticed on the user end, since the touchpad + keyboard were already frozen. kern.log: http://paste.ubuntu.com/552617/ How can the freezes be fixed? Edit: I will try Ctrl+Alt+F1 and then Ctrl+Alt+F7 when next freeze occurs, to see if it works again after this, as suggested here. But the keyboard seemed pretty frozen to me.

• Issue with gpg agent in Ubuntu 12.04 after installing gnome3 shell

  - by Jeroen

  I just did a fresh install of Ubuntu 12.04. Initially things were working. But after I installed some software, the 'gpg agent' is unresponsive. I suspect it has something to do with upgrades that I downloaded from the gnome 3 ppa. When I try to sign a package, it terminates with: gpg: problem with the agent - disabling agent use debsign: gpg error occurred! Aborting.... debuild: fatal error at line 1271: running debsign failed The GPG gui tool (called "Passwords and Keys" or seahorse) isn't starting anymore either. When I click it, it tries to start and then gives up and dies after a couple of seconds. I am not sure where to look for log files of gpg agent. The only thing that I see in /var/log is in auth.log that says: May 1 20:04:14 jeroen-ubuntu gnome-keyring-daemon[1997]: couldn't create prompt for gnupg passphrase: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.keyring.SystemPrompter was not provided by any .service files Not sure if it is related, but when I try to start seahorse from the command line, I get: jeroen@jeroen-ubuntu:~$ seahorse (seahorse:4828): GLib-GIO-ERROR **: Settings schema 'org.gnome.crypto.pgp' is not installed Edit: I fixed the seahorse GUI by manually downloading and reinstalling gnome-keyring version from precise instead of the ppa. However, I still cannot sign packages.

• ASP.NET MVC localization DisplayNameAttribute alternatives: a good way

  - by Brian Schroer

  The ASP.NET MVC HTML helper methods like .LabelFor and .EditorFor use model metadata to autogenerate labels for model properties. By default it uses the property name for the label text, but if that’s not appropriate, you can use a DisplayName attribute to specify the desired label text: [DisplayName("Remember me?")] public bool RememberMe { get; set; } I’m working on a multi-language web site, so the labels need to be localized. I tried pointing the DisplayName attribute to a resource string: [DisplayName(MyResource.RememberMe)] public bool RememberMe { get; set; } …but that results in the compiler error "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type”. I got around this by creating a custom LocalizedDisplayNameAttribute class that inherits from DisplayNameAttribute: 1: public class LocalizedDisplayNameAttribute : DisplayNameAttribute 2: { 3: public LocalizedDisplayNameAttribute(string resourceKey) 4: { 5: ResourceKey = resourceKey; 6: } 7:   8: public override string DisplayName 9: { 10: get 11: { 12: string displayName = MyResource.ResourceManager.GetString(ResourceKey); 13:   14: return string.IsNullOrEmpty(displayName) 15: ? string.Format("[[{0}]]", ResourceKey) 16: : displayName; 17: } 18: } 19:   20: private string ResourceKey { get; set; } 21: } Instead of a display string, it takes a constructor argument of a resource key. The DisplayName method is overridden to get the display string from the resource file (line 12). If the key is not found, I return a formatted string containing the key (e.g. “[[RememberMe]]”) so I can tell by looking at my web pages which resource keys I haven’t defined yet (line 15). The usage of my custom attribute in the model looks like this: [LocalizedDisplayName("RememberMe")] public bool RememberMe { get; set; } That was my first attempt at localized display names, and it’s a technique that I still use in some cases, but in my next post I’ll talk about the method that I now prefer, a custom DataAnnotationsModelMetadataProvider class…

• How Do I Implement parameterMaps for ADF Regions and Dynamic Regions?

  - by david.giammona

  parameterMap objects defined by managed beans can help reduce the number of child <parameter> elements listed under an ADF region or dynamic region page definition task flow binding. But more importantly, the parameterMap approach also allows greater flexibility in determining what input parameters are passed to an ADF region or dynamic region. This can be especially helpful when using dynamic regions where each task flow utilized can provide an entirely different set of input parameters. The parameterMap is specified within an ADF region or dynamic region page definition task flow binding as shown below: <taskFlow id="checkoutflow1" taskFlowId="/WEB-INF/checkout-flow.xml#checkout-flow" activation="deferred" xmlns="http://xmlns.oracle.com/adf/controller/binding" parametersMap="#{pageFlowScope.userInfoBean.parameterMap}"/> The parameter map object must implement the java.util.Map interface. The keys it specifies match the names of input parameters defined by the task flows utilized within the task flow binding. An example parameterMap object class is shown below: import java.util.HashMap; import java.util.Map; public class UserInfoBean { private Map<String, Object> parameterMap = new HashMap<String, Object>(); public Map getParameterMap() { parameterMap.put("isLoggedIn", getSecurity().isAuthenticated()); parameterMap.put("principalName", getSecurity().getPrincipalName()); return parameterMap; }

• Windows Embedded CE DiskPrep PowerToy

  - by Bruce Eitman

  Kurt Kennett from Microsoft has offered up a handy new tool. This tool is useful for creating a boot disk for x86 Windows CE systems that use the BIOSLoader. This is especially useful for creating disks with formats other than FAT16, which are fairly easy to create. I am letting you know about this new tool, but I have to be honest in telling you that I haven’t used it myself because it is for Windows Vista and Windows 7 – which I don’t have available right now. But you can bet that I will be setting up a virtual machine to give it a try. Here is what Kurt has to say about the tool: Download the DiskPrep Tool  DiskPrep can prepare any hard disk that can be attached to your development PC so that it can boot your X86-based Windows CE OS Design. USB disks (including disk "keys"), Compact Flash Cards, and SD cards all work if your system bios can boot from that type of media. FAT16, FAT32, and exFAT all supported. DOS is not used - the program prepares the bios loader on the disk and only uses that. If you use Windows Vista or Windows 7, you can use VHD files for VirtualPC. This allows for rapid prototyping of a self-booting system. Copyright © 2010 – Bruce Eitman All Rights Reserved

• Running a simple integration scenario using the Oracle Big Data Connectors on Hadoop/HDFS cluster

  - by hamsun

  Between the elephant ( the tradional image of the Hadoop framework) and the Oracle Iron Man (Big Data..) an english setter could be seen as the link to the right data Data, Data, Data, we are living in a world where data technology based on popular applications , search engines, Webservers, rich sms messages, email clients, weather forecasts and so on, have a predominant role in our life. More and more technologies are used to analyze/track our behavior, try to detect patterns, to propose us "the best/right user experience" from the Google Ad services, to Telco companies or large consumer sites (like Amazon:) ). The more we use all these technologies, the more we generate data, and thus there is a need of huge data marts and specific hardware/software servers (as the Exadata servers) in order to treat/analyze/understand the trends and offer new services to the users. Some of these "data feeds" are raw, unstructured data, and cannot be processed effectively by normal SQL queries. Large scale distributed processing was an emerging infrastructure need and the solution seemed to be the "collocation of compute nodes with the data", which in turn leaded to MapReduce parallel patterns and the development of the Hadoop framework, which is based on MapReduce and a distributed file system (HDFS) that runs on larger clusters of rather inexpensive servers. Several Oracle products are using the distributed / aggregation pattern for data calculation ( Coherence, NoSql, times ten ) so once that you are familiar with one of these technologies, lets says with coherence aggregators, you will find the whole Hadoop, MapReduce concept very similar. Oracle Big Data Appliance is based on the Cloudera Distribution (CDH), and the Oracle Big Data Connectors can be plugged on a Hadoop cluster running the CDH distribution or equivalent Hadoop clusters. In this paper, a "lab like" implementation of this concept is done on a single Linux X64 server, running an Oracle Database 11g Enterprise Edition Release 11.2.0.4.0, and a single node Apache hadoop-1.2.1 HDFS cluster, using the SQL connector for HDFS. The whole setup is fairly simple: Install on a Linux x64 server ( or virtual box appliance) an Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 server Get the Apache Hadoop distribution from: http://mir2.ovh.net/ftp.apache.org/dist/hadoop/common/hadoop-1.2.1. Get the Oracle Big Data Connectors from: http://www.oracle.com/technetwork/bdc/big-data-connectors/downloads/index.html?ssSourceSiteId=ocomen. Check the java version of your Linux server with the command: java -version java version "1.7.0_40" Java(TM) SE Runtime Environment (build 1.7.0_40-b43) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode) Decompress the hadoop hadoop-1.2.1.tar.gz file to /u01/hadoop-1.2.1 Modify your .bash_profile export HADOOP_HOME=/u01/hadoop-1.2.1 export PATH=$PATH:$HADOOP_HOME/bin export HIVE_HOME=/u01/hive-0.11.0 export PATH=$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin (also see my sample .bash_profile) Set up ssh trust for Hadoop process, this is a mandatory step, in our case we have to establish a "local trust" as will are using a single node configuration copy the new public keys to the list of authorized keys connect and test the ssh setup to your localhost: We will run a "pseudo-Hadoop cluster", in what is called "local standalone mode", all the Hadoop java components are running in one Java process, this is enough for our demo purposes. We need to "fine tune" some Hadoop configuration files, we have to go at our $HADOOP_HOME/conf, and modify the files: core-site.xml hdfs-site.xml mapred-site.xml check that the hadoop binaries are referenced correctly from the command line by executing: hadoop -version As Hadoop is managing our "clustered HDFS" file system we have to create "the mount point" and format it , the mount point will be declared to core-site.xml as: The layout under the /u01/hadoop-1.2.1/data will be created and used by other hadoop components (MapReduce = /mapred/...) HDFS is using the /dfs/... layout structure format the HDFS hadoop file system: Start the java components for the HDFS system As an additional check, you can use the GUI Hadoop browsers to check the content of your HDFS configurations: Once our HDFS Hadoop setup is done you can use the HDFS file system to store data ( big data : )), and plug them back and forth to Oracle Databases by the means of the Big Data Connectors ( which is the next configuration step). You can create / use a Hive db, but in our case we will make a simple integration of "raw data" , through the creation of an External Table to a local Oracle instance ( on the same Linux box, we run the Hadoop HDFS one node cluster and one Oracle DB). Download some public "big data", I use the site: http://france.meteofrance.com/france/observations, from where I can get *.csv files for my big data simulations :). Here is the data layout of my example file: Download the Big Data Connector from the OTN (oraosch-2.2.0.zip), unzip it to your local file system (see picture below) Modify your environment in order to access the connector libraries , and make the following test: [oracle@dg1 bin]$./hdfs_stream Usage: hdfs_stream locationFile [oracle@dg1 bin]$ Load the data to the Hadoop hdfs file system: hadoop fs -mkdir bgtest_data hadoop fs -put obsFrance.txt bgtest_data/obsFrance.txt hadoop fs -ls /user/oracle/bgtest_data/obsFrance.txt [oracle@dg1 bg-data-raw]$ hadoop fs -ls /user/oracle/bgtest_data/obsFrance.txt Found 1 items -rw-r--r-- 1 oracle supergroup 54103 2013-10-22 06:10 /user/oracle/bgtest_data/obsFrance.txt [oracle@dg1 bg-data-raw]$hadoop fs -ls hdfs:///user/oracle/bgtest_data/obsFrance.txt Found 1 items -rw-r--r-- 1 oracle supergroup 54103 2013-10-22 06:10 /user/oracle/bgtest_data/obsFrance.txt Check the content of the HDFS with the browser UI: Start the Oracle database, and run the following script in order to create the Oracle database user, the Oracle directories for the Oracle Big Data Connector (dg1 it’s my own db id replace accordingly yours): #!/bin/bash export ORAENV_ASK=NO export ORACLE_SID=dg1 . oraenv sqlplus /nolog <<EOF CONNECT / AS sysdba; CREATE OR REPLACE DIRECTORY osch_bin_path AS '/u01/orahdfs-2.2.0/bin'; CREATE USER BGUSER IDENTIFIED BY oracle; GRANT CREATE SESSION, CREATE TABLE TO BGUSER; GRANT EXECUTE ON sys.utl_file TO BGUSER; GRANT READ, EXECUTE ON DIRECTORY osch_bin_path TO BGUSER; CREATE OR REPLACE DIRECTORY BGT_LOG_DIR as '/u01/BG_TEST/logs'; GRANT READ, WRITE ON DIRECTORY BGT_LOG_DIR to BGUSER; CREATE OR REPLACE DIRECTORY BGT_DATA_DIR as '/u01/BG_TEST/data'; GRANT READ, WRITE ON DIRECTORY BGT_DATA_DIR to BGUSER; EOF Put the following in a file named t3.sh and make it executable, hadoop jar $OSCH_HOME/jlib/orahdfs.jar \ oracle.hadoop.exttab.ExternalTable \ -D oracle.hadoop.exttab.tableName=BGTEST_DP_XTAB \ -D oracle.hadoop.exttab.defaultDirectory=BGT_DATA_DIR \ -D oracle.hadoop.exttab.dataPaths="hdfs:///user/oracle/bgtest_data/obsFrance.txt" \ -D oracle.hadoop.exttab.columnCount=7 \ -D oracle.hadoop.connection.url=jdbc:oracle:thin:@//localhost:1521/dg1 \ -D oracle.hadoop.connection.user=BGUSER \ -D oracle.hadoop.exttab.printStackTrace=true \ -createTable --noexecute then test the creation fo the external table with it: [oracle@dg1 samples]$ ./t3.sh ./t3.sh: line 2: /u01/orahdfs-2.2.0: Is a directory Oracle SQL Connector for HDFS Release 2.2.0 - Production Copyright (c) 2011, 2013, Oracle and/or its affiliates.

• Getting Query Parameters in Javascript

  - by PhubarBaz

  I find myself needing to get query parameters that are passed into a web app on the URL quite often. At first I wrote a function that creates an associative array (aka object) with all of the parameters as keys and returns it. But then I was looking at the revealing module pattern, a nice javascript design pattern designed to hide private functions, and came up with a way to do this without even calling a function. What I came up with was this nice little object that automatically initializes itself into the same associative array that the function call did previously. // Creates associative array (object) of query params var QueryParameters = (function() {     var result = {};     if (window.location.search)     {         // split up the query string and store in an associative array         var params = window.location.search.slice(1).split("&");         for (var i = 0; i < params.length; i++)         {             var tmp = params[i].split("=");             result[tmp[0]] = unescape(tmp[1]);         }     }     return result; }()); Now all you have to do to get the query parameters is just reference them from the QueryParameters object. There is no need to create a new object or call any function to initialize it. var debug = (QueryParameters.debug === "true"); or if (QueryParameters["debug"]) doSomeDebugging(); or loop through all of the parameters. for (var param in QueryParameters) var value = QueryParameters[param]; Hope you find this object useful.

• Using an Apt Repository for Paid Software Updates

  - by Scott Warren

  I'm trying to determine a way to distribute software updates for a hosted/on-site web application that may have weekly and/or monthly updates. I don't want the customers who use the on-site product to have to worry about updating it manually I just want it to download and install automatically ala Google Chrome. I'm planning on providing an OVF file with Ubuntu and the software installed and configured. My first thought on how to distributed software is to create six Apt repositories/channels (not sure which would be better at this point) that will be accessed through SSH using keys so if a customer doesn't renew their subscription we can disable their account: Beta - Used internally on test data to check the package for major defects. Internal - Used internally on live data to check the package for defects (dog fooding stage). External 1 - Deployed to 1% of our user base (randomly selected) to check for defects. External 9 - Deployed to 9% of our user base (ramdonly selected) to check for defects. External 90 - Deployed to the remaining 90% of users. Hosted - Deployed to the hosted environment. It will take a sign off at each stage to move into the next repository in case problems are reported. My questions to the community are: Has anyone tried something like this before? Can anyone see a downside to this type of a procedure? Is there a better way?

• Ubuntu backlight problem with Nvidia graphics

  - by Vladimir

  I have a laptop mySN QMG6 / Chiligreen Mobilitas NW which is Quanta TW9 barebone with intel i3 and nvidia 335m GT onboard. On ubuntu distros 10.04, 10.10, 11.04 and 11.10 i had problem with changing screen backlight with nouveau and nvidia drivers. FN+F4/F5 buttons did not change my brightness. I tried to edit xorg.conf, adding Option “RegistryDwords” “EnableBrightnessControl=1? Also tried to add some lines to grug acpi_osi="Linux" acpi_backlight=vendor Neither worked for me. Today I installed Ubuntu 12.04 beta2 and... With nouveau driver my FN key works, and changes the brightness (is it a new 3.0.22 linux kernel, or patched nouveau driver, i don't know). This is a big step forward. But, when installing proprietary nvidia driver (295.33) FN button stops working and i can't change brightness. I also tried workaround with xorg and grub with no result. Tried to install acpi from apt - no result. Is there anything left to try? I really need that nvidia driver working with FN keys, as i would like to have a working 3D acceleration. P.S. Does the nouveau driver has 3d acceleration like nvidia drivers??? If there is need to provide some log data, please write what should i print, as i'm a bit new to Ubuntu. P.P.S. Same problems i had with other Linux distros (Mint, Fedora and others) P.P.P.S. Other FN buttons work with both drivers (Mute, VOL UP/DOWN, WiFi on/off, Bluetooth, Sleep, Start/Pause, Stop, Next/Prev song)

• Jumping Vs. Gravity

  - by PhaDaPhunk

  Hi i'm working on my first XNA 2D game and I have a little problem. If I jump, my sprite jumps but does not fall down. And I also have another problem, the user can hold spacebar to jump as high as he wants and I don't know how to keep him from doing that. Here's my code: The Jump : if (FaKeyboard.IsKeyDown(Keys.Space)) { Jumping = true; xPosition -= new Vector2(0, 5); } if (xPosition.Y >= 10) { Jumping = false; Grounded = false; } The really simple basic Gravity: if (!Grounded && !Jumping) { xPosition += new Vector2(1, 3) * speed; } Here's where's the grounded is set to True or False with a Collision Rectangle MegamanRectangle = new Rectangle((int)xPosition.X, (int)xPosition.Y, FrameSizeDraw.X, FrameSizeDraw.Y); Rectangle Block1Rectangle = new Rectangle((int)0, (int)73, Block1.Width, Block1.Height); Rectangle Block2Rectangle = new Rectangle((int)500, (int)73, Block2.Width, Block2.Height); if ((MegamanRectangle.Intersects(Block1Rectangle) || (MegamanRectangle.Intersects(Block2Rectangle)))) { Grounded = true; } else { Grounded = false; } The grounded bool and The gravity have been tested and are working. Any ideas why? Thanks in advance and don't hesitate to ask if you need another Part of the Code.

• Bind the windows key to Lubuntu start menu

  - by abel

  I am running Lubuntu 11.10. By default the main menu is bound to Alt+F1 (A-F1) which works. Here is the relevant code from ~/.config/openbox/lubuntu-rc.xml <keybind key="A-F1"> <action name="Execute"> <command>lxpanelctl menu</command> </action> </keybind> This works. When I hit Alt+F1, I can see the start menu. If I change the keys to "Windows key + M" (W-m), I can pull up the start menu using Win+M <keybind key="W-m"> <action name="Execute"> <command>lxpanelctl menu</command> </action> </keybind> However, I cannot bind the start menu to the Windows key alone. If I try replacing "W-m" by "W", the "W" alphabet key gets bound to the start menu. If I try "W-" nothing happens, I have tried the "Super" option too but to no avail. How can I bind the Lubuntu main menu to the windows Key? I have been through some relevant lubuntu questions, like this one, which tries to do the opposite. How do I unbind Super key from menu in Lubuntu

• Rhythmbox 2.99.1 crashes when playing any song on Ubuntu 13.10

  - by John H

  Yesterday rhythmbox was running smoothly but today it crashes only a few seconds after I hit the play button, regardless of track. I've tried disabling plugins, re-installing rhythmbox via synaptics, clearing the library and the rhythmdb.xml-file and just adding one album. Still, it crashes. If I run the rhythmbox from the command line i get the following before I have to force quit: :~$ rhythmbox Failed to create secure directory (/run/user/1000/pulse): Permission denied Killed :~$ However, if i run rhythmbox via the command line as superuser it does work. But i get the following errors: sudo rhythmbox (rhythmbox:8335): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files (rhythmbox:8335): IBUS-WARNING **: The owner of /home/john/.config/ibus/bus is not root!

• disable all hotkeys with dconf-editor

  - by Gijs

  I'm building a deb package that will create a kiosk user account. When you login to this account, the browser automatically starts and navigates to a pre-given website. Also all the hotkeys should be disabled except for one you defined. Now I'm at the part that the browser starts and my disable script is excecuted on logon but for exaple, I can still close the browser with Alt + F4. And when i check the dconf-editor for the hotkeys, for every single one the bind is deleted, but mine for close isn't added. Like you can see in the printscreen. I disabled all these keys with this code, one line for evere hotkey gsettings set org.gnome.desktop.wm.keybindings begin-resize [] So this seams to work, but at the bottom of my disable script this line should be executed. gsettings set org.gnome.desktop.wm.keybindings close ['<Alt>b'] Does anyone know why i'm able to unbind all these hotkeys in my dconf-editor but they are able to still do their job? And when it is possible to unbind them, why cant I bind mine? I searched the web for a solution but couldn't find one fitting my needs, I hope some of you know the answer to this. Regards Gijs

• Use a Free Utility to Create Multiple Virtual Desktops in Windows

  - by Lori Kaufman

  If you’ve used Linux, you’re probably familiar with the virtual desktop feature. It provides a convenient way to organize programs and folders open on your desktop. You can switch among multiple desktops and have different programs and folders open on each one. However, virtual desktops is a feature missing in Windows. There are many third-party options for adding virtual desktops to Windows, including one called Dexpot, which we have covered previously. Dexpot is free, but only for private use. Companies, public institutions, non-profit organizations, and even freelancers and self-employed people must buy the program. We found another virtual desktop tool that is completely free for everyone to use, called mDesktop. It’s a lightweight, open source program that allows you to switch among multiple desktops using hot keys and specify open programs or folders to be active on all desktops. You can use mDesktop to group related programs or to work on different projects on separate desktops. mDesktop is portable and does not need to be installed. Simply extract the .zip file you downloaded (see the link at the end of this article) and double-click the mDesktop.exe file.

• Pygame Tile Based Character movement speed

  - by Ryan

  Thanks for taking the time to read this. Right now I'm making a really basic tile based game. The map is a large amount of 16x16 tiles, and the character image is 16x16 as well. My character has its own class that is an extension of the sprite class, and the x and y position is saved in terms of the tile position. To note I am fairly new to pygame. My question is, I am planning to have character movement restricted to one tile at a time, and I'm not sure how to make it so that, even if the player hits the directional key dozens of time quickly, (WASD or arrow keys) it will only move from tile to tile at a certain speed. How could I implement this generally with pygame? (Similar to game movement of like Pokemon or NexusTk). Edit: I should probably note that I want it so that the player can only end a movement in a tile. He couldn't stop moving halfway inbetween a tile for example. Thanks for your time! Ryan

  - by Pinal Dave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 FQL – Facebook Query Language Facebook list following advantages of FQL: Condensed XML reduces bandwidth and parsing costs. More complex requests can reduce the number of requests necessary. Provides a single consistent, unified interface for all of your data. It’s fun! UDF – Get the Day of the Week Function The day of the week can be retrieved in SQL Server by using the DatePart function. The value returned by the function is between 1 (Sunday) and 7 (Saturday). To convert this to a string representing the day of the week, use a CASE statement. UDF – Function to Get Previous And Next Work Day – Exclude Saturday and Sunday While reading ColdFusion blog of Ben Nadel Getting the Previous Day In ColdFusion, Excluding Saturday And Sunday, I realize that I use similar function on my SQL Server Database. This function excludes the Weekends (Saturday and Sunday), and it gets previous as well as next work day.

DBCC SHRINKFILE Takes Long Time to Run If you are DBA who are involved with Database Maintenance and file group maintenance, you must have experience that many times DBCC SHRINKFILE operations takes a long time but any other operations with Database are relatively quicker. mssqlsystemresource – Resource Database The purpose of resource database is to facilitates upgrading to the new version of SQL Server without any hassle. In previous versions whenever version of SQL Server was upgraded all the previous version system objects needs to be dropped and new version system objects to be created. 2009 Puzzle – Write Script to Generate Primary Key and Foreign Key In SQL Server Management Studio (SSMS), there is no option to script all the keys. If one is required to script keys they will have to manually script each key one at a time. If database has many tables, generating one key at a time can be a very intricate task. I want to throw a question to all of you if any of you have scripts for the same purpose. Maximizing View of SQL Server Management Studio – Full Screen – New Screen I had explained the following two different methods: 1) Open Results in Separate Tab - This is a very interesting method as result pan shows up in a different tab instead of the splitting screen horizontally. 2) Open SSMS in Full Screen - This works always and to its best. Not many people are aware of this method; hence, very few people use it to enhance performance. 2010 Find Queries using Parallelism from Cached Plan T-SQL script gets all the queries and their execution plan where parallelism operations are kicked up.

SQL SERVER – Interview Questions and Answers – Guest Post by Rick Morelan – Day 27 of 31 Rick Morelan of Joes2Pros has written an excellent blog post on the subject how to find top N values. Most people are fully aware of how the TOP keyword works with a SELECT statement. After years preparing so many students to pass the SQL Certification I noticed they were pretty well prepared for job interviews too. Yes, they would do well in the interview but not great. There seemed to be a few questions that would come up repeatedly for almost everyone. Rick addresses similar questions in his lucid writing skills. 2012 Observation of Top with Index and Order of Resultset SQL Server has lots of things to learn and share. It is amazing to see how people evaluate and understand different techniques and styles differently when implementing. The real reason may be absolutely different but we may blame something totally different for the incorrect results. Read the blog post to learn more. How do I Record Video and Webcast How to Convert Hex to Decimal or INT Earlier I asked regarding a question about how to convert Hex to Decimal. I promised that I will post an answer with Due Credit to the author but never got around to post a blog post around it. Read the original post over here SQL SERVER – Question – How to Convert Hex to Decimal. Query to Get Unique Distinct Data Based on Condition – Eliminate Duplicate Data from Resultset The natural reaction will be to suggest DISTINCT or GROUP BY. However, not all the questions can be solved by DISTINCT or GROUP BY. Let us see the following example, where a user wanted only latest records to be displayed. Let us see the example to understand further.
