• MySQL Connector/Net 6.4.6 Maintenance Release has been released

  - by fernando

  MySQL Connector/Net 6.4.6, a new version of the all-managed .NET driver for MySQL has been released.  This is a maintenance release and is recommended for use in production environments. It is appropriate for use with MySQL server versions 5.0-5.6. This is intended to be the final release for Connector/NET 6.4. It is now available in source and binary form from http://dev.mysql.com/downloads/connector/net/#downloads and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.) The 6.4.6 version of MySQL Connector/Net brings the following fixes: - Fix for List.Contains generates a bunch of ORs instead of more efficient IN clause in   LINQ to Entities (Oracle bug #14016344, MySql bug #64934). - Fix for error when trying to change the name of an Index on the Indexes/Keys editor; along with this fix now users can change the Index type of a new Index which could not be done   in previous versions, and when changing the Index name the change is reflected on the list view at the left side of the Index/Keys editor (Oracle bug #13613801). - Fix for stored procedure call using only its name with EF code first (MySql bug #64999, Oracle bug #14008699). - Fix for performance issue in generated EF query: .NET StartsWith/Contains/EndsWith produces MySql's locate instead of Like (MySql bug #64935, Oracle bug #14009363). - Fix for script generated for code first contains wrong alter table and wrong declaration for byte[] (MySql bug #64216, Oracle bug #13900091). - Fix for Exception thrown when using cascade delete in an EDM Model-First in Entity Framework (Oracle bug #14008752, MySql bug #64779). - Fix for Session locking issue with MySqlSessionStateStore (MySql bug #63997, Oracble bug #13733054). - Fixed deleting a user profile using Profile provider (MySQL bug #64409, Oracle bug #13790123). - Fix for bug Cannot Create an Entity with a Key of Type String (MySQL bug #65289, Oracle bug #14540202). This fix checks if the type has a FixedLength facet set in order to create a char otherwise should create varchar, mediumtext or longtext types when using a String CLR type in Code First or Model First also tested in Database First. Unit tests added for Code First and ProviderManifest. - Fix for bug "CacheServerProperties can cause 'Packet too large' error" (MySQL Bug #66578 Orabug #14593547). - Fix for handling unnamed parameter in MySQLCommand. This fix allows the mysqlcommand to handle parameters without requiring naming (e.g. INSERT INTO Test (id,name) VALUES (?, ?) ) (MySQL Bug #66060, Oracle bug #14499549). - Fixed inheritance on Entity Framework Code First scenarios. Discriminator column is created using its correct type as varchar(128) (MySql bug #63920 and Oracle bug #13582335). - Fixed "Trying to customize column precision in Code First does not work" (MySql bug #65001, Oracle bug #14469048). - Fixed bug ASP.NET Membership database fails on MySql database UTF32 (MySQL bug #65144, Oracle bug #14495292). - Fix for MySqlCommand.LastInsertedId holding only 32 bit values (MySql bug #65452, Oracle bug #14171960) by changing   several internal declaration of lastinsertid from int to long. - Fixed "Decimal type should have digits at right of decimal point", now default is 2, but user's changes in   EDM designer are recognized (MySql bug #65127, Oracle bug #14474342). - Fix for NullReferenceException when saving an uninitialized row in Entity Framework (MySql bug #66066, Oracle bug #14479715). - Fix for error when calling RoleProvider.RemoveUserFromRole(): causes an exception due to a wrong table being used (MySql bug #65805, Oracle bug #14405338). - Fix for "Memory Leak on MySql.Data.MySqlClient.MySqlCommand", too many MemoryStream's instances created (MySql bug #65696, Oracle bug #14468204). - Small improvement on MySqlPoolManager CleanIdleConnections for better mysqlpoolmanager idlecleanuptimer at startup (MySql bug #66472 and Oracle bug #14652624). - Fix for bug TIMESTAMP values are mistakenly represented as DateTime with Kind = Local (Mysql bug #66964, Oracle bug #14740705). - Fix for bug Keyword not supported. Parameter name: AttachDbFilename (Mysql bug #66880, Oracle bug #14733472). - Added support to MySql script file to retrieve data when using "SHOW" statements. - Fix for Package Load Failure in Visual Studio 2005 (MySql bug #63073, Oracle bug #13491674). - Fix for bug "Unable to connect using IPv6 connections" (MySQL bug #67253, Oracle bug #14835718). - Added auto-generated values for Guid identity columns (MySql bug #67450, Oracle bug #15834176). - Fix for method FirstOrDefault not supported in some LINQ to Entities queries (MySql bug #67377, Oracle bug #15856964).

• TDD and WCF behavior

  - by Frederic Hautecoeur

  Some weeks ago I wanted to develop a WCF behavior using TDD. I have lost some time trying to use mocks. After a while i decided to just use a host and a client. I don’t like this approach but so far I haven’t found a good and fast solution to use Unit Test for testing a WCF behavior. To Implement my solution I had to : Create a Dummy Service Definition; Create the Dummy Service Implementation; Create a host; Create a client in my test; Create and Add the behavior; Dummy Service Definition This is just a simple service, composed of an Interface and a simple implementation. The structure is aimed to be easily customizable for my future needs.   Using Clauses : 1: using System.Runtime.Serialization; 2: using System.ServiceModel; 3: using System.ServiceModel.Channels; The DataContract: 1: [DataContract()] 2: public class MyMessage 3: { 4: [DataMember()] 5: public string MessageString; 6: } The request MessageContract: 1: [MessageContract()] 2: public class RequestMessage 3: { 4: [MessageHeader(Name = "MyHeader", Namespace = "http://dummyservice/header", Relay = true)] 5: public string myHeader; 6:  7: [MessageBodyMember()] 8: public MyMessage myRequest; 9: } The response MessageContract: 1: [MessageContract()] 2: public class ResponseMessage 3: { 4: [MessageHeader(Name = "MyHeader", Namespace = "http://dummyservice/header", Relay = true)] 5: public string myHeader; 6:  7: [MessageBodyMember()] 8: public MyMessage myResponse; 9: } The ServiceContract: 1: [ServiceContract(Name="DummyService", Namespace="http://dummyservice",SessionMode=SessionMode.Allowed )] 2: interface IDummyService 3: { 4: [OperationContract(Action="Perform", IsOneWay=false, ProtectionLevel=System.Net.Security.ProtectionLevel.None )] 5: ResponseMessage DoThis(RequestMessage request); 6: } Dummy Service Implementation 1: public class DummyService:IDummyService 2: { 3: #region IDummyService Members 4: public ResponseMessage DoThis(RequestMessage request) 5: { 6: ResponseMessage response = new ResponseMessage(); 7: response.myHeader = "Response"; 8: response.myResponse = new MyMessage(); 9: response.myResponse.MessageString = 10: string.Format("Header:<{0}> and Request was <{1}>", 11: request.myHeader, request.myRequest.MessageString); 12: return response; 13: } 14: #endregion 15: } Host Creation The most simple host implementation using a Named Pipe binding. The GetBinding method will create a binding for the host and can be used to create the same binding for the client. 1: public static class TestHost 2: { 3: 4: internal static string hostUri = "net.pipe://localhost/dummy"; 5:  6: // Create Host method. 7: internal static ServiceHost CreateHost() 8: { 9: ServiceHost host = new ServiceHost(typeof(DummyService)); 10:  11: // Creating Endpoint 12: Uri namedPipeAddress = new Uri(hostUri); 13: host.AddServiceEndpoint(typeof(IDummyService), GetBinding(), namedPipeAddress); 14:  15: return host; 16: } 17:  18: // Binding Creation method. 19: internal static Binding GetBinding() 20: { 21: NamedPipeTransportBindingElement namedPipeTransport = new NamedPipeTransportBindingElement(); 22: TextMessageEncodingBindingElement textEncoding = new TextMessageEncodingBindingElement(); 23:  24: return new CustomBinding(textEncoding, namedPipeTransport); 25: } 26:  27: // Close Method. 28: internal static void Close(ServiceHost host) 29: { 30: if (null != host) 31: { 32: host.Close(); 33: host = null; 34: } 35: } 36: } Checking the service A simple test tool check the plumbing. 1: [TestMethod] 2: public void TestService() 3: { 4: using (ServiceHost host = TestHost.CreateHost()) 5: { 6: host.Open(); 7:  8: using (ChannelFactory<IDummyService> channel = 9: new ChannelFactory<IDummyService>(TestHost.GetBinding() 10: , new EndpointAddress(TestHost.hostUri))) 11: { 12: IDummyService svc = channel.CreateChannel(); 13: try 14: { 15: RequestMessage request = new RequestMessage(); 16: request.myHeader = Guid.NewGuid().ToString(); 17: request.myRequest = new MyMessage(); 18: request.myRequest.MessageString = "I want some beer."; 19:  20: ResponseMessage response = svc.DoThis(request); 21: } 22: catch (Exception ex) 23: { 24: Assert.Fail(ex.Message); 25: } 26: } 27: host.Close(); 28: } 29: } Running the service should show that the client and the host are running fine. So far so good. Adding the Behavior Add a reference to the Behavior project and add the using entry in the test class. We just need to add the behavior to the service host : 1: [TestMethod] 2: public void TestService() 3: { 4: using (ServiceHost host = TestHost.CreateHost()) 5: { 6: host.Description.Behaviors.Add(new MyBehavior()); 7: host.Open();¨ 8: …  If you set a breakpoint in your behavior and run the test in debug mode, you will hit the breakpoint. In this case I used a ServiceBehavior. To add an Endpoint behavior you have to add it to the endpoints. 1: host.Description.Endpoints[0].Behaviors.Add(new MyEndpointBehavior()) To add a contract or an operation behavior a custom attribute should work on the service contract definition. I haven’t tried that yet.   All the code provided in this blog and in the following files are for sample use. Improvements I don’t like to instantiate a client and a service to test my behaviors. But so far I have' not found an easy way to do it. Today I am passing a type of endpoint to the host creator and it creates the right binding type. This allows me to easily switch between bindings at will. I have used the same approach to test Mex Endpoints, another post should come later for this. Enjoy !

• World Record Batch Rate on Oracle JD Edwards Consolidated Workload with SPARC T4-2

  - by Brian

  Oracle produced a World Record batch throughput for single system results on Oracle's JD Edwards EnterpriseOne Day-in-the-Life benchmark using Oracle's SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2. The workload includes both online and batch workload. The SPARC T4-2 server delivered a result of 8,000 online users while concurrently executing a mix of JD Edwards EnterpriseOne Long and Short batch processes at 95.5 UBEs/min (Universal Batch Engines per minute). In order to obtain this record benchmark result, the JD Edwards EnterpriseOne, Oracle WebLogic and Oracle Database 11g Release 2 servers were executed each in separate Oracle Solaris Containers which enabled optimal system resources distribution and performance together with scalable and manageable virtualization. One SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2 utilized only 55% of the available CPU power. The Oracle DB server in a Shared Server configuration allows for optimized CPU resource utilization and significant memory savings on the SPARC T4-2 server without sacrificing performance. This configuration with SPARC T4-2 server has achieved 33% more Users/core, 47% more UBEs/min and 78% more Users/rack unit than the IBM Power 770 server. The SPARC T4-2 server with 2 processors ran the JD Edwards "Day-in-the-Life" benchmark and supported 8,000 concurrent online users while concurrently executing mixed batch workloads at 95.5 UBEs per minute. The IBM Power 770 server with twice as many processors supported only 12,000 concurrent online users while concurrently executing mixed batch workloads at only 65 UBEs per minute. This benchmark demonstrates more than 2x cost savings by consolidating the complete solution in a single SPARC T4-2 server compared to earlier published results of 10,000 users and 67 UBEs per minute on two SPARC T4-2 and SPARC T4-1. The Oracle DB server used mirrored (RAID 1) volumes for the database providing high availability for the data without impacting performance. Performance Landscape JD Edwards EnterpriseOne Day in the Life (DIL) Benchmark Consolidated Online with Batch Workload System Rack Units BatchRate(UBEs/m) Online Users Users /Units Users /Core Version SPARC T4-2 (2 x SPARC T4, 2.85 GHz) 3 95.5 8,000 2,667 500 9.0.2 IBM Power 770 (4 x POWER7, 3.3 GHz, 32 cores) 8 65 12,000 1,500 375 9.0.2 Batch Rate (UBEs/m) — Batch transaction rate in UBEs per minute Configuration Summary Hardware Configuration: 1 x SPARC T4-2 server with 2 x SPARC T4 processors, 2.85 GHz 256 GB memory 4 x 300 GB 10K RPM SAS internal disk 2 x 300 GB internal SSD 2 x Sun Storage F5100 Flash Arrays Software Configuration: Oracle Solaris 10 Oracle Solaris Containers JD Edwards EnterpriseOne 9.0.2 JD Edwards EnterpriseOne Tools (8.98.4.2) Oracle WebLogic Server 11g (10.3.4) Oracle HTTP Server 11g Oracle Database 11g Release 2 (11.2.0.1) Benchmark Description JD Edwards EnterpriseOne is an integrated applications suite of Enterprise Resource Planning (ERP) software. Oracle offers 70 JD Edwards EnterpriseOne application modules to support a diverse set of business operations. Oracle's Day in the Life (DIL) kit is a suite of scripts that exercises most common transactions of JD Edwards EnterpriseOne applications, including business processes such as payroll, sales order, purchase order, work order, and manufacturing processes, such as ship confirmation. These are labeled by industry acronyms such as SCM, CRM, HCM, SRM and FMS. The kit's scripts execute transactions typical of a mid-sized manufacturing company. The workload consists of online transactions and the UBE – Universal Business Engine workload of 61 short and 4 long UBEs. LoadRunner runs the DIL workload, collects the user’s transactions response times and reports the key metric of Combined Weighted Average Transaction Response time. The UBE processes workload runs from the JD Enterprise Application server. Oracle's UBE processes come as three flavors: Short UBEs < 1 minute engage in Business Report and Summary Analysis, Mid UBEs > 1 minute create a large report of Account, Balance, and Full Address, Long UBEs > 2 minutes simulate Payroll, Sales Order, night only jobs. The UBE workload generates large numbers of PDF files reports and log files. The UBE Queues are categorized as the QBATCHD, a single threaded queue for large and medium UBEs, and the QPROCESS queue for short UBEs run concurrently. Oracle's UBE process performance metric is Number of Maximum Concurrent UBE processes at transaction rate, UBEs/minute. Key Points and Best Practices Two JD Edwards EnterpriseOne Application Servers, two Oracle WebLogic Servers 11g Release 1 coupled with two Oracle Web Tier HTTP server instances and one Oracle Database 11g Release 2 database on a single SPARC T4-2 server were hosted in separate Oracle Solaris Containers bound to four processor sets to demonstrate consolidation of multiple applications, web servers and the database with best resource utilizations. Interrupt fencing was configured on all Oracle Solaris Containers to channel the interrupts to processors other than the processor sets used for the JD Edwards Application server, Oracle WebLogic servers and the database server. A Oracle WebLogic vertical cluster was configured on each WebServer Container with twelve managed instances each to load balance users' requests and to provide the infrastructure that enables scaling to high number of users with ease of deployment and high availability. The database log writer was run in the real time RT class and bound to a processor set. The database redo logs were configured on the raw disk partitions. The Oracle Solaris Container running the Enterprise Application server completed 61 Short UBEs, 4 Long UBEs concurrently as the mixed size batch workload. The mixed size UBEs ran concurrently from the Enterprise Application server with the 8,000 online users driven by the LoadRunner.

• doubleTwist is an iTunes Alternative that Supports Several Devices

  - by Mysticgeek

  There are a lot of iTunes users out there, but unfortunately you can’t use it with all of your portable devices. Today we take a look at doubleTwist, which allows you to sync your media with a multitude of portable devices and easily share it as well. Note: You can run doubleTwist on Windows or Mac, and here we take a look at the Windows version. Install & Setup doubleTwist Download and install doubleTwist using the defaults in the wizard… Installation takes several moments and you’ll see the progress while it finishes up. After installation is complete, sign up for an account if you don’t already have one. If you do have an account you can login right away. Enter in your username, email address, and password then click Sign Up.   You’ll get an confirmation email and need to activate the account before you can sign in. Once you’re all signed up, launch doubleTwist and you’ll be ready to start using it. doubleTwist Music The default music store is Amazon MP3 store which might appeal to those of you who are tired of the iTunes music store. A lot of times the music is cheaper and available at higher bit rates. You can start searching for music in the Amazon Music Store and previewing songs. To purchase anything though you will need to sign into your Amazon account.   Under Playlists it allows you to import your playlists from iTunes and Windows Media Player, which is a handy feature if you don’t want to set them up again. Of course you can play your songs through the music player on your desktop. Devices One of the coolest things about doubleTwist is that it supports a lot of different portable media devices including iPod, BlackBerry, Windows Mobile, Android, PSP, Smartphones, and much more. Unfortunately for Zune users…there isn’t any support for the Zune of Zune HD yet. Here we have a Creative Zen attached and can sync songs, pictures, and podcasts. An HTC-S620 Smartphone running Windows Mobile… Even a simple USB drive will be recognized and you can transfer your media to it as well.   Podcasts Finding your favorite audio and video podcasts is easy with the search feature. You can easily manage and subscribe to podcasts in the subscriptions section.   You can watch the video podcasts directly in doubleTwist. Sharing Media Also you can share digital media with your friends or add it to Flickr and YouTube. You can send any pictures, videos, or music in your library to other people by dragging it over. You can email users individually… Or access contacts from your Gmail and Yahoo accounts. There is a limit to how much you can send of video podcasts… only the first 10 minutes. The person you send it to will get a link in their email that points to your My Feed page on the doubleTwist site.   There they can access the media you sent…in this example it’s a video podcast but you can share any media. Other Features Under My Profile you can change your avatar and personal information.   In Preferences you can choose where media is stored, its startup actions, podcast subscriptions, and manage device syncing. Conclusion It’s still in beta stage so expect some bugs, but overall doubleTwist is a solid media player that is easy to use with a clean interface. It’s simple and doesn’t try to do too much so is fairly easy on system resources. The main annoyance is it tries to catalog all of your media out of the box. Which may be alright for some users with smaller media collections, but very irritating to advanced users with large collections. Also there is currently no support for the Zune, but according to their forums, it’s on the way. At the time of this writing it’s in public beta and can be downloaded for XP, Vista, Windows 7 (32 & 64 bit), and Mac OSX. If you’re looking for an iTunes alternative that works with several different portable devices, you might want to give DoubleTwist a try.

• Prevent Changing the Screen Saver and Wallpaper in Windows 7

  - by Mysticgeek

  Sometimes you might not want users to have the ability to change Screen Savers and Wallpaper on Windows 7 workstations. Today we look at how to prevent them from changing either one or both. You might administer computers in your home or small office and find it annoying when users continuously change the wallpaper and Screen Savers to something obnoxious. A lot of times they might be inexperienced users and download these so-called “wonderful and free” Screen Saver/Wallpaper packages from shady sites that include loads of Spyware. Preventing users from changing them is another helpful tool to avoid wasteful time spent switching things back. Prevent Changing Screensavers & Wallpaper Using Group Policy Editor  Note: This method uses Group Policy which is not available in Home versions on Windows 7. Open the Start Menu and enter gpedit.msc into the Search box and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates \ Control Panel \ Personalization. Then in the right column double-click on Prevent changing desktop background. Now check the radio button next to Enabled, then click OK. Back on the Group Policy Screen, double-click on Prevent changing screen saver. In the next screen select the radio button next to Enable, click OK, then close out of Group Policy Editor. Now when a user goes into the Personalization section, the Desktop Background hyperlink is now grayed out and inactive. Notice the message One or more of the settings on this page has been disabled by the system administrator at the bottom of the section. If they click to change the Screen Saver, an error message will pop up letting them know the function is disabled. Prevent Changing Screensavers & Wallpaper Using a Registry Hack You can also make a couple Registry changes to prevent users from changing the Wallpaper & Screen Saver…which will work on Home versions of Windows 7. Before making any Registry changes make sure you back it up first. Open the Registry by typing regedit into the Search box in the Start menu and hit Enter. First we’ll start with the Wallpaper. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new String Value and name it Wallpaper. Then modify the Value data to point to the location of the Wallpaper you want it to always be. Where in this example it’s our main wallpaper on our local drive…then click OK. Now let’s make sure they can’t change the Screen Saver. In the same Registry location, we need to make a new DWORD (32-bit) Value. Give it the Value name of NoDispScrSavPage and the value data of “1” and click OK. Close out of the Registry and restart the machine or simply log off then back on again for the changes to take effect. Results For the Wallpapers, a user can still go in and see the selections, however if they try to change it to something else… It will just go back to the Personalization screen and no changes will be made, as we set the value to only be the background we specified. If the user tries to make a change to the Screen Saver, the hyperlink will be grayed out and inactive, and the message One or more of the settings on this page has been disabled by the system administrator will be displayed at the bottom of the section. Conclusion If you’re tired of users changing the Wallpaper and Screen Saver, and want another way to help avoid Malware, locking down these settings can help a lot. Again, before making any changes to the Registry, make sure to back it up. These settings should work in Vista and XP as well.

• Create Orchard Module in a Separate Project

  - by Steve Michelotti

  The Orchard Project is a new OOS Microsoft project that is being developed up on CodePlex. From the Orchard home page on CodePlex, it states “Orchard project is focused on delivering a .NET-based CMS application that will allow users to rapidly create content-driven Websites, and an extensibility framework that will allow developers and customizers to provide additional functionality through modules and themes.” The Orchard Project site contains additional information including documentation and walkthroughs. The ability to create a composite solution based on a collection of modules is a compelling feature. In Orchard, these modules can just be created as simple MVC Areas or they can also be created inside of stand-alone web application projects.  The walkthrough for writing an Orchard module that is available on the Orchard site uses a simple Area that is created inside of the host application. It is based on the Orchard MIX presentation. This walkthrough does an effective job introducing various Orchard concepts such as hooking into the navigation system, theme/layout system, content types, and more.  However, creating an Orchard module in a separate project does not seem to be concisely documented anywhere. Orchard ships with several module OOTB that are in separate assemblies – but again, it’s not well documented how to get started building one from scratch. The following are the steps I took to successfully get an Orchard module in a separate project up and running. Step 1 – Download the OrchardIIS.zip file from the Orchard Release page. Unzip and open up the solution. Step 2 – Add your project to the solution. I named my project “Orchard.Widget” and used and “MVC 2 Empty Web Application” project type. Make sure you put the physical path inside the “Modules” sub-folder to the main project like this: At this point the solution should look like: Step 3 – Add assembly references to Orchard.dll and Orchard.Core.dll. Step 4 – Add a controller and view.  I’ll just create a Hello World controller and view. Notice I created the view as a partial view (*.ascx). Also add the [Themed] attribute to the top of the HomeController class just like the normal Orchard walk through shows it. Step 5 – Add Module.txt to the project root. The is a very important step. Orchard will not recognize your module without this text file present.  It can contain just the name of your module: name: Widget Step 6 – Add Routes.cs. Notice I’ve given an area name of “Orchard.Widget” on lines 26 and 33. 1: using System; 2: using System.Collections.Generic; 3: using System.Web.Mvc; 4: using System.Web.Routing; 5: using Orchard.Mvc.Routes; 6:   7: namespace Orchard.Widget 8: { 9: public class Routes : IRouteProvider 10: { 11: public void GetRoutes(ICollection<RouteDescriptor> routes) 12: { 13: foreach (var routeDescriptor in GetRoutes()) 14: { 15: routes.Add(routeDescriptor); 16: } 17: } 18:   19: public IEnumerable<RouteDescriptor> GetRoutes() 20: { 21: return new[] { 22: new RouteDescriptor { 23: Route = new Route( 24: "Widget/{controller}/{action}/{id}", 25: new RouteValueDictionary { 26: {"area", "Orchard.Widget"}, 27: {"controller", "Home"}, 28: {"action", "Index"}, 29: {"id", ""} 30: }, 31: new RouteValueDictionary(), 32: new RouteValueDictionary { 33: {"area", "Orchard.Widget"} 34: }, 35: new MvcRouteHandler()) 36: } 37: }; 38: } 39: } 40: } Step 7 – Add MainMenu.cs. This will make sure that an item appears in the main menu called “Widget” which points to the module. 1: using System; 2: using Orchard.UI.Navigation; 3:   4: namespace Orchard.Widget 5: { 6: public class MainMenu : INavigationProvider 7: { 8: public void GetNavigation(NavigationBuilder builder) 9: { 10: builder.Add(menu => menu.Add("Widget", item => item.Action("Index", "Home", new 11: { 12: area = "Orchard.Widget" 13: }))); 14: } 15:   16: public string MenuName 17: { 18: get { return "main"; } 19: } 20: } 21: } Step 8 – Clean up web.config. By default Visual Studio adds numerous sections to the web.config. The sections that can be removed are: appSettings, connectionStrings, authentication, membership, profile, and roleManager. Step 9 – Delete Global.asax. This project will ultimately be running from inside the Orchard host so this “sub-site” should not have its own Global.asax.   Now you’re ready the run the app.  When you first run it, the “Widget” menu item will appear in the main menu because of the MainMenu.cs file we added: We can then click the “Widget” link in the main menu to send us over to our view:   Packaging From start to finish, it’s a relatively painless experience but it could be better. For example, a Visual Studio project template that encapsulates aspects from this blog post would definitely make it a lot easier to get up and running with creating an Orchard module.  Another aspect I found interesting is that if you read the first paragraph of the walkthrough, it says, “You can also develop modules as separate projects, to be packaged and shared with other users of Orchard CMS (the packaging story is still to be defined, along with marketplaces for sharing modules).” In particular, I will be extremely curious to see how the “packaging story” evolves. The first thing that comes to mind for me is: what if we explored MvcContrib Portable Areas as a potential mechanism for this packaging? This would certainly make things easy since all artifacts (aspx, aspx, images, css, javascript) are all wrapped up into a single assembly. Granted, Orchard does have its own infrastructure for layouts and themes but it seems like integrating portable areas into this pipeline would not be a difficult undertaking. Maybe that’ll be the next research task. :)

  My Ubuntu is booting really slow (Windows is booting faster...).

• Implementing an Interceptor Using NHibernate’s Built In Dynamic Proxy Generator

  - by Ricardo Peres

  NHibernate 3.2 came with an included proxy generator, which means there is no longer the need – or the possibility, for that matter – to choose Castle DynamicProxy, LinFu or Spring. This is actually a good thing, because it means one less assembly to deploy. Apparently, this generator was based, at least partially, on LinFu. As there are not many tutorials out there demonstrating it’s usage, here’s one, for demonstrating one of the most requested features: implementing INotifyPropertyChanged. This interceptor, of course, will still feature all of NHibernate’s functionalities that you are used to, such as lazy loading, and such. We will start by implementing an NHibernate interceptor, by inheriting from the base class NHibernate.EmptyInterceptor. This class does not do anything by itself, but it allows us to plug in behavior by overriding some of its methods, in this case, Instantiate: 1: public class NotifyPropertyChangedInterceptor : EmptyInterceptor 2: { 3: private ISession session = null; 4:  5: private static readonly ProxyFactory factory = new ProxyFactory(); 6:  7: public override void SetSession(ISession session) 8: { 9: this.session = session; 10: base.SetSession(session); 11: } 12:  13: public override Object Instantiate(String clazz, EntityMode entityMode, Object id) 14: { 15: Type entityType = Type.GetType(clazz); 16: IProxy proxy = factory.CreateProxy(entityType, new _NotifyPropertyChangedInterceptor(), typeof(INotifyPropertyChanged)) as IProxy; 17: 18: _NotifyPropertyChangedInterceptor interceptor = proxy.Interceptor as _NotifyPropertyChangedInterceptor; 19: interceptor.Proxy = this.session.SessionFactory.GetClassMetadata(entityType).Instantiate(id, entityMode); 20:  21: this.session.SessionFactory.GetClassMetadata(entityType).SetIdentifier(proxy, id, entityMode); 22:  23: return (proxy); 24: } 25: } Then we need a class that implements the NHibernate dynamic proxy behavior, let’s place it inside our interceptor, because it will only need to be used there: 1: class _NotifyPropertyChangedInterceptor : NHibernate.Proxy.DynamicProxy.IInterceptor 2: { 3: private PropertyChangedEventHandler changed = delegate { }; 4:  5: public Object Proxy 6: { 7: get; 8: set;} 9:  10: #region IInterceptor Members 11:  12: public Object Intercept(InvocationInfo info) 13: { 14: Boolean isSetter = info.TargetMethod.Name.StartsWith("set_") == true; 15: Object result = null; 16:  17: if (info.TargetMethod.Name == "add_PropertyChanged") 18: { 19: PropertyChangedEventHandler propertyChangedEventHandler = info.Arguments[0] as PropertyChangedEventHandler; 20: this.changed += propertyChangedEventHandler; 21: } 22: else if (info.TargetMethod.Name == "remove_PropertyChanged") 23: { 24: PropertyChangedEventHandler propertyChangedEventHandler = info.Arguments[0] as PropertyChangedEventHandler; 25: this.changed -= propertyChangedEventHandler; 26: } 27: else 28: { 29: result = info.TargetMethod.Invoke(this.Proxy, info.Arguments); 30: } 31:  32: if (isSetter == true) 33: { 34: String propertyName = info.TargetMethod.Name.Substring("set_".Length); 35: this.changed(this.Proxy, new PropertyChangedEventArgs(propertyName)); 36: } 37:  38: return (result); 39: } 40:  41: #endregion 42: } What this does for every interceptable method (those who are either virtual or from the INotifyPropertyChanged) is: For methods that came from the INotifyPropertyChanged interface, add_PropertyChanged and remove_PropertyChanged (yes, events are methods ), we add an implementation that adds or removes the event handlers to the delegate which we declared as changed; For all the others, we direct them to the place where they are actually implemented, which is the Proxy field; If the call is setting a property, it fires afterwards the PropertyChanged event. In order to use this, we need to add the interceptor to the Configuration before building the ISessionFactory: 1: using (ISessionFactory factory = cfg.SetInterceptor(new NotifyPropertyChangedInterceptor()).BuildSessionFactory()) 2: { 3: using (ISession session = factory.OpenSession()) 4: using (ITransaction tx = session.BeginTransaction()) 5: { 6: Customer customer = session.Get<Customer>(100); //some id 7: INotifyPropertyChanged inpc = customer as INotifyPropertyChanged; 8: inpc.PropertyChanged += delegate(Object sender, PropertyChangedEventArgs e) 9: { 10: //fired when a property changes 11: }; 12: customer.Address = "some other address"; //will raise PropertyChanged 13: customer.RecentOrders.ToList(); //will trigger the lazy loading 14: } 15: } Any problems, questions, do drop me a line!

• MySQL Connector/Net 6.5.5 Maintenance Release has been released

  - by fernando

  MySQL Connector/Net 6.5.5, a new maintenance release of our 6.5 series, has been released.  This release is GA quality and is appropriate for use in production environments.  Please note that 6.6 is our latest driver series and is the recommended product for development. It is now available in source and binary form from http://dev.mysql.com/downloads/connector/net/#downloads and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.) The 6.5.5 version of MySQL Connector/Net brings the following fixes: - Fix for ArgumentNull exception when using Take().Count() in a LINQ to Entities query (bug MySql #64749, Oracle bug #13913047). - Fix for type varchar changed to bit when saving in Table Designer (Oracle bug #13916560). - Fix for error when trying to change the name of an Index on the Indexes/Keys editor; along with this fix now users can change the Index type of a new Index which could not be done   in previous versions, and when changing the Index name the change is reflected on the list view at the left side of the Index/Keys editor (Oracle bug #13613801). - Fix for stored procedure call using only its name with EF code first (MySql bug #64999, Oracle bug #14008699). - Fix for List.Contains generates a bunch of ORs instead of more efficient IN clause in   LINQ to Entities (Oracle bug #14016344, MySql bug #64934). - Fix for performance issue in generated EF query: .NET StartsWith/Contains/EndsWith produces MySql's locate instead of Like (MySql bug #64935, Oracle bug #14009363). - Fix for script generated for code first contains wrong alter table and wrong declaration for byte[] (MySql bug #64216, Oracle bug #13900091). - Fix and code contribution for bug Timed out sessions are removed without notification which allow to enable the Expired CallBack when Session Provider times out any session (bug MySql #62266 Oracle bug # 13354935) - Fix for Exception thrown when using cascade delete in an EDM Model-First in Entity Framework (Oracle bug #14008752, MySql bug #64779). - Fix for Session locking issue with MySqlSessionStateStore (MySql bug #63997, Oracble bug #13733054). - Fixed deleting a user profile using Profile provider (MySQL bug #64470, Oracle bug #13790123) - Fix for bug Cannot Create an Entity with a Key of Type String (MySQL bug #65289, Oracle bug #14540202). This fix checks if the type has a FixedLength facet set in order to create a char otherwise should create varchar, mediumtext or longtext types when using a String CLR type in Code First or Model First also tested in Database First. Unit tests added for Code First and ProviderManifest. - Fix for bug "CacheServerProperties can cause 'Packet too large' error". The issue was due to a missing reading of Max_allowed_packet server property when CacheServerProperties is in true, since the value was read only in the first connection but the following pooled connections had a wrong value causing a Packet too large error. Including also a unit test for this scenario. All unit test passed. MySQL Bug #66578 Orabug #14593547. - Fix for handling unnamed parameter in MySQLCommand. This fix allows the mysqlcommand to handle parameters without requiring naming (e.g. INSERT INTO Test (id,name) VALUES (?, ?) ) (MySQL Bug #66060, Oracle bug #14499549). - Fixed inheritance on Entity Framework Code First scenarios. Discriminator column is created using its correct type as varchar(128) (MySql bug #63920 and Oracle bug #13582335). - Fixed "Trying to customize column precision in Code First does not work" (MySql bug #65001, Oracle bug #14469048). - Fixed bug ASP.NET Membership database fails on MySql database UTF32 (MySQL bug #65144, Oracle bug #14495292). - Fix for MySqlCommand.LastInsertedId holding only 32 bit values (MySql bug #65452, Oracle bug #14171960) by changing   several internal declaration of lastinsertid from int to long. - Fixed "Decimal type should have digits at right of decimal point", now default is 2, but user's changes in   EDM designer are recognized (MySql bug #65127, Oracle bug #14474342). - Fix for NullReferenceException when saving an uninitialized row in Entity Framework (MySql bug #66066, Oracle bug #14479715). - Fix for error when calling RoleProvider.RemoveUserFromRole(): causes an exception due to a wrong table being used (MySql bug #65805, Oracle bug #14405338). - Fix for "Memory Leak on MySql.Data.MySqlClient.MySqlCommand", too many MemoryStream's instances created (MySql bug #65696, Oracle bug #14468204). - Added ANTLR attribution notice (Oracle bug #14379162). - Fixed Entity Framework + mysql connector/net in partial trust throws exceptions (MySql bug #65036, Oracle bug #14668820). - Added support in Parser for Datetime and Time types with precision when using Server 5.6 (No bug Number). - Small improvement on MySqlPoolManager CleanIdleConnections for better mysqlpoolmanager idlecleanuptimer at startup (MySql bug #66472 and Oracle bug #14652624). - Fix for bug TIMESTAMP values are mistakenly represented as DateTime with Kind = Local (Mysql bug #66964, Oracle bug #14740705). - Fix for bug Keyword not supported. Parameter name: AttachDbFilename (Mysql bug #66880, Oracle bug #14733472). - Added support to MySql script file to retrieve data when using "SHOW" statements. - Fix for Package Load Failure in Visual Studio 2005 (MySql bug #63073, Oracle bug #13491674). - Fix for bug "Unable to connect using IPv6 connections" (MySQL bug #67253, Oracle bug #14835718). - Added auto-generated values for Guid identity columns (MySql bug #67450, Oracle bug #15834176). - Fix for method FirstOrDefault not supported in some LINQ to Entities queries (MySql bug #67377, Oracle bug #15856964).

• [GEEK SCHOOL] Network Security 3: Windows Defender and a Malware-Free System

  - by Ciprian Rusen

  In this second lesson we are going to talk about one of the most confusing security products that are bundled with Windows: Windows Defender. In the past, this product has had a bad reputation and for good reason – it was very limited in its capacity to protect your computer from real-world malware. However, the latest version included in Windows 8.x operating systems is much different than in the past and it provides real protection to its users. The nice thing about Windows Defender in its current incarnation, is that it protects your system from the start, so there are never gaps in coverage. We will start this lesson by explaining what Windows Defender is in Windows 7 and Vista versus what it is in Windows 8, and what product to use if you are using an earlier version. We next will explore how to use Windows Defender, how to improve its default settings, and how to deal with the alerts that it displays. As you will see, Windows Defender will have you using its list of quarantined items a lot more often than other security products. This is why we will explain in detail how to work with it and remove malware for good or restore those items that are only false alarms. Lastly, you will learn how to turn off Windows Defender if you no longer want to use it and you prefer a third-party security product in its place and then how to enable it back, if you have changed your mind about using it. Upon completion, you should have a thorough understanding of your system’s default anti-malware options, or how to protect your system expeditiously. What is Windows Defender? Unfortunately there is no one clear answer to this question because of the confusing way Microsoft has chosen to name its security products. Windows Defender is a different product, depending on the Windows operating system you are using. If you use Windows Vista or Windows 7, then Windows Defender is a security tool that protects your computer from spyware. This but one form of malware made out of tools and applications that monitor your movements on the Internet or the activities you make on your computer. Spyware tends to send the information that is collected to a remote server and it is later used in all kinds of malicious purposes, from displaying advertising you don’t want, to using your personal data, etc. However, there are many other types of malware on the Internet and this version of Windows Defender is not able to protect users from any of them. That’s why, if you are using Windows 7 or earlier, we strongly recommend that you disable Windows Defender and install a more complete security product like Microsoft Security Essentials, or third-party security products from specialized security vendors. If you use Windows 8.x operating systems, then Windows Defender is the same thing as Microsoft Security Essentials: a decent security product that protects your computer in-real time from viruses and spyware. The fact that this product protects your computer also from viruses, not just from spyware, makes a huge difference. If you don’t want to pay for security products, Windows Defender in Windows 8.x and Microsoft Security Essentials (in Windows 7 or earlier) are good alternatives. Windows Defender in Windows 8.x and Microsoft Security Essentials are the same product, only their name is different. In this lesson, we will use the Windows Defender version from Windows 8.x but our instructions apply also to Microsoft Security Essentials (MSE) in Windows 7 and Windows Vista. If you want to download Microsoft Security Essentials and try it out, we recommend you to use this page: Download Microsoft Security Essentials. There you will find both 32-bit and 64-bit editions of this product as well versions in multiple languages. How to Use and Configure Windows Defender Using Windows Defender (MSE) is very easy to use. To start, search for “defender” on the Windows 8.x Start screen and click or tap the “Windows Defender” search result. In Windows 7, search for “security” in the Start Menu search box and click “Microsoft Security Essentials”. Windows Defender has four tabs which give you access to the following tools and options: Home – here you can view the security status of your system. If everything is alright, then it will be colored in green. If there are some warnings to consider, then it will be colored in yellow, and if there are threats that must be dealt with, everything will be colored in red. On the right side of the “Home” tab you will find options for scanning your computer for viruses and spyware. On the bottom of the tab you will find information about when the last scan was performed and what type of scan it was. Update – here you will find information on whether this product is up-to-date. You will learn when it was last updated and the versions of the definitions it is using. You can also trigger a manual update. History – here you can access quarantined items, see which items you’ve allowed to run on your PC even if they were identified as malware by Windows Defender, and view a complete list with all the malicious items Windows Defender has detected on your PC. In order to access all these lists and work with them, you need to be signed in as an administrator. Settings – this is the tab where you can turn on the real-time protection service, exclude files, file types, processes, and locations from its scans as well as access a couple of more advanced settings. The only difference between Windows Defender in Windows 8.x and Microsoft Security Essentials (in Windows 7 or earlier) is that, in the “Settings” tab, Microsoft Security Essentials allows you to set when to run scheduled scans while Windows Defender lacks this option.

• List of Commonly Used Value Types in XNA Games

  - by Michael B. McLaughlin

  Most XNA programmers are concerned about generating garbage. More specifically about allocating GC-managed memory (GC stands for “garbage collector” and is both the name of the class that provides access to the garbage collector and an acronym for the garbage collector (as a concept) itself). Two of the major target platforms for XNA (Windows Phone 7 and Xbox 360) use variants of the .NET Compact Framework. On both variants, the GC runs under various circumstances (Windows Phone 7 and Xbox 360). Of concern to XNA programmers is the fact that it runs automatically after a fixed amount of GC-managed memory has been allocated (currently 1MB on both systems). Many beginning XNA programmers are unaware of what constitutes GC-managed memory, though. So here’s a quick overview. In .NET, there are two different “types” of types: value types and reference types. Only reference types are managed by the garbage collector. Value types are not managed by the garbage collector and are instead managed in other ways that are implementation dependent. For purposes of XNA programming, the important point is that they are not managed by the GC and thus do not, by themselves, increment that internal 1 MB allocation counter. (n.b. Structs are value types. If you have a struct that has a reference type as a member, then that reference type, when instantiated, will still be allocated in the GC-managed memory and will thus count against the 1 MB allocation counter. Putting it in a struct doesn’t change the fact that it gets allocated on the GC heap, but the struct itself is created outside of the GC’s purview). Both value types and reference types use the keyword ‘new’ to allocate a new instance of them. Sometimes this keyword is hidden by a method which creates new instances for you, e.g. XmlReader.Create. But the important thing to determine is whether or not you are dealing with a value types or a reference type. If it’s a value type, you can use the ‘new’ keyword to allocate new instances of that type without incrementing the GC allocation counter (except as above where it’s a struct with a reference type in it that is allocated by the constructor, but there are no .NET Framework or XNA Framework value types that do this so it would have to be a struct you created or that was in some third-party library you were using for that to even become an issue). The following is a list of most all of value types you are likely to use in a generic XNA game: AudioCategory (used with XACT; not available on WP7) AvatarExpression (Xbox 360 only, but exposed on Windows to ease Xbox development) bool BoundingBox BoundingSphere byte char Color DateTime decimal double any enum (System.Enum itself is a class, but all enums are value types such that there are no GC allocations for enums) float GamePadButtons GamePadCapabilities GamePadDPad GamePadState GamePadThumbSticks GamePadTriggers GestureSample int IntPtr (rarely but occasionally used in XNA) KeyboardState long Matrix MouseState nullable structs (anytime you see, e.g. int? something, that ‘?’ denotes a nullable struct, also called a nullable type) Plane Point Quaternion Ray Rectangle RenderTargetBinding sbyte (though I’ve never seen it used since most people would just use a short) short TimeSpan TouchCollection TouchLocation TouchPanelCapabilities uint ulong ushort Vector2 Vector3 Vector4 VertexBufferBinding VertexElement VertexPositionColor VertexPositionColorTexture VertexPositionNormalTexture VertexPositionTexture Viewport So there you have it. That’s not quite a complete list, mind you. For example: There are various structs in the .NET framework you might make use of. I left out everything from the Microsoft.Xna.Framework.Graphics.PackedVector namespace, since everything in there ventures into the realm of advanced XNA programming anyway (n.b. every single instantiable thing in that namespace is a struct and thus a value type; there are also two interfaces but interfaces cannot be instantiated at all and thus don’t figure in to this discussion). There are so many enums you’re likely to use (PlayerIndex, SpriteSortMode, SpriteEffects, SurfaceFormat, etc.) that including them would’ve flooded the list and reduced its utility. So I went with “any enum” and trust that you can figure out what the enums are (and it’s rare to use ‘new’ with an enum anyway). That list also doesn’t include any of the pre-defined static instances of some of the classes (e.g. BlendState.AlphaBlend, BlendState.Opaque, etc.) which are already allocated such that using them doesn’t cause any new allocations and therefore doesn’t increase that 1 MB counter. That list also has a few misleading things. VertexElement, VertexPositionColor, and all the other vertex types are structs. But you’re only likely to ever use them as an array (for use with VertexBuffer or DynamicVertexBuffer), and all arrays are reference types (even arrays of value types such as VertexPositionColor[ ] or int[ ]). * So that’s it for now. The note below may be a bit confusing (it deals with how the GC works and how arrays are managed in .NET). If so, you can probably safely ignore it for now but feel free to ask any questions regardless. * Arrays of value types (where the value type doesn’t contain any reference type members) are much faster for the GC to examine than arrays of reference types, so there is a definite benefit to using arrays of value types where it makes sense. But creating arrays of value types does cause the GC’s allocation counter to increase. Indeed, allocating a large array of a value type is one of the quickest ways to increment the allocation counter since a .NET array is a sequential block of memory. An array of reference types is just a sequential block of references (typically 4 bytes each) while an array of value types is a sequential block of instances of that type. So for an array of Vector3s it would be 12 bytes each since each float is 4 bytes and there are 3 in a Vector3; for an array of VertexPositionNormalTexture structs it would typically be 32 bytes each since it has two Vector3s and a Vector2. (Note that there are a few additional bytes taken up in the creation of an array, typically 12 but sometimes 16 or possibly even more, which depend on the implementation details of the array type on the particular platform the code is running on).

• Demystified - BI in SharePoint 2010

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Frequently, my clients ask me if there is a good guide on deciphering the seemingly daunting choice of products from Microsoft when it comes to business intelligence offerings in a SharePoint 2010 world. These are all described in detail in my book, but here is a one (well maybe two) page executive overview. Microsoft Excel: Yes, Microsoft Excel! Your favorite and most commonly used in the world database. No it isn’t a database in technical pure definitions, but this is the most commonly used ‘database’ in the world. You will find many business users craft up very compelling excel sheets with tonnes of logic inside them. Good for: Quick Ad-Hoc reports. Excel 64 bit allows the possibility of very large datasheets (Also see 32 bit vs 64 bit Office, and PowerPivot Add-In below). Audience: End business user can build such solutions. Related technologies: PowerPivot, Excel Services Microsoft Excel with PowerPivot Add-In: The powerpivot add-in is an extension to Excel that adds support for large-scale data. Think of this as Excel with the ability to deal with very large amounts of data. It has an in-memory data store as an option for Analysis services. Good for: Ad-hoc reporting and logic with very large amounts of data. Audience: End business user can build such solutions. Related technologies: Excel, and Excel Services Excel Services: Excel Services is a Microsoft SharePoint Server 2010 shared service that brings the power of Excel to SharePoint Server by providing server-side calculation and browser-based rendering of Excel workbooks. Thus, excel sheets can be created by end users, and published to SharePoint server – which are then rendered right through the browser in read-only or parameterized-read-only modes. They can also be accessed by other software via SOAP or REST based APIs. Good for: Sharing excel sheets with a larger number of people, while maintaining control/version control etc. Sharing logic embedded in excel sheets with other software across the organization via REST/SOAP interfaces Audience: End business users can build such solutions once your tech staff has setup excel services on a SharePoint server instance. Programmers can write software consuming functionality/complex formulae contained in your sheets. Related technologies: PerformancePoint Services, Excel, and PowerPivot. Visio Services: Visio Services is a shared service on the Microsoft SharePoint Server 2010 platform that allows users to share and view Visio diagrams that may or may not have data connected to them. Connected data can update these diagrams allowing a visual/graphical view into the data. The diagrams are viewable through the browser. They are rendered in silverlight, but will automatically down-convert to .png formats. Good for: Showing data as diagrams, live updating. Comes with a developer story. Audience: End business users can build such solutions once your tech staff has setup visio services on a SharePoint server instance. Developers can enhance the visualizations Related Technologies: Visio Services can be used to render workflow visualizations in SP2010 Reporting Services: SQL Server reporting services can integrate with SharePoint, allowing you to store reports and data sources in SharePoint document libraries, and render these reports and associated functionality such as subscriptions through a SharePoint site. In SharePoint 2010, you can also write reports against SharePoint lists (access services uses this technique). Good for: Showing complex reports running in a industry standard data store, such as SQL server. Audience: This is definitely developer land. Don’t expect end users to craft up reports, unless a report model has previously been published. Related Technologies: PerformancePoint Services PerformancePoint Services: PerformancePoint Services in SharePoint 2010 is now fully integrated with SharePoint, and comes with features that can either be used in the BI center site definition, or on their own as activated features in existing site collections. PerformancePoint services allows you to build reports and dashboards that target a variety of back-end datasources including: SQL Server reporting services, SQL Server analysis services, SharePoint lists, excel services, simple tables, etc. Using these you have the ability to create dashboards, scorecards/kpis, and simple reports. You can also create reports targeting hierarchical multidimensional data sources. The visual decomposition tree is a new report type that lets you quickly breakdown multi-dimensional data. Good for: Mostly everything :), except your wallet – it’s not free! But this is the most comprehensive offering. If you have SharePoint server, forget everything and go with performance point. Audience: Developers need to setup the back-end sources, manageability story. DBAs need to setup datawarehouses with cubes. Moderately sophisticated business users, or developers can craft up reports using dashboard designer which is a click-once App that deploys with PerformancePoint Related Technologies: Excel services, reporting services, etc.   Other relevant technologies to know about: Business Connectivity Services: Allows for consumption of external data in SharePoint as columns or external lists. This can be paired with one or more of the above BI offerings allowing insight into such data. Access Services: Allows the representation/publishing of an access database as a SharePoint 2010 site, leveraging many SharePoint features. Reporting services is used by Access services. Secure Store Service: The SP2010 Secure store service is a replacement for the SP2007 single sign on feature. This acts as a credential policeman providing credentials to various applications running with SharePoint. BCS, PerformancePoint Services, Excel Services, and many other apps use the SSS (Secure Store Service) for credential control. Comment on the article ....

• Simple Preferred time control using silverlight 3.

  - by mohanbrij

  Here I am going to show you a simple preferred time control, where you can select the day of the week and the time of the day. This can be used in lots of place where you may need to display the users preferred times. Sample screenshot is attached below. This control is developed using Silverlight 3 and VS2008, I am also attaching the source code with this post. This is a very basic example. You can download and customize if further for your requirement if you want. I am trying to explain in few words how this control works and what are the different ways in which you can customize it further. File: PreferredTimeControl.xaml, in this file I have just hardcoded the controls and their positions which you can see in the screenshot above. In this example, to change the start day of the week and time, you will have to go and change the design in XAML file, its not controlled by your properties or implementation classes. You can also customize it to change the start day of the week, Language, Display format, styles, etc, etc. File: PreferredTimeControl.xaml.cs, In this control using the code below, first I am taking all the checkbox from my form and store it in the Global Variable, which I can use across my page. List<CheckBox> checkBoxList; #region Constructor public PreferredTimeControl() { InitializeComponent(); GetCheckboxes();//Keep all the checkbox in List in the Load itself } #endregion #region Helper Methods private List<CheckBox> GetCheckboxes() { //Get all the CheckBoxes in the Form checkBoxList = new List<CheckBox>(); foreach (UIElement element in LayoutRoot.Children) { if (element.GetType().ToString() == "System.Windows.Controls.CheckBox") { checkBoxList.Add(element as CheckBox); } } return checkBoxList; } Then I am exposing the two methods which you can use in the container form to get and set the values in this controls. /// <summary> /// Set the Availability on the Form, with the Provided Timings /// </summary> /// <param name="selectedTimings">Provided timings comes from the DB in the form 11,12,13....37 /// Where 11 refers to Monday Morning, 12 Tuesday Morning, etc /// Here 1, 2, 3 is for Morning, Afternoon and Evening respectively, and for weekdays /// 1,2,3,4,5,6,7 where 1 is for Monday, Tuesday, Wednesday, Thrusday, Friday, Saturday and Sunday respectively /// So if we want Monday Morning, we can can denote it as 11, similarly for Saturday Evening we can write 36, etc /// </param> public void SetAvailibility(string selectedTimings) { foreach (CheckBox chk in checkBoxList) { chk.IsChecked = false; } if (!String.IsNullOrEmpty(selectedTimings)) { string[] selectedString = selectedTimings.Split(','); foreach (string selected in selectedString) { foreach (CheckBox chk in checkBoxList) { if (chk.Tag.ToString() == selected) { chk.IsChecked = true; } } } } } /// <summary> /// Gets the Availibility from the selected checkboxes /// </summary> /// <returns>String in the format of 11,12,13...41,42...31,32...37</returns> public string GetAvailibility() { string selectedText = string.Empty; foreach (CheckBox chk in GetCheckboxes()) { if (chk.IsChecked == true) { selectedText = chk.Tag.ToString() + "," + selectedText; } } return selectedText; }   In my example I am using the matrix format for Day and Time, for example Monday=1, Tuesday=2, Wednesday=3, Thursday = 4, Friday = 5, Saturday = 6, Sunday=7. And Morning = 1, Afternoon =2, Evening = 3. So if I want to represent Morning-Monday I will have to represent it as 11, Afternoon-Tuesday as 22, Morning-Wednesday as 13, etc. And in the other way to set the values in the control I am passing the values in the control in the same format as preferredTimeControl.SetAvailibility("11,12,13,16,23,22"); So this will set the checkbox value for Morning-Monday, Morning-Tuesday, Morning-Wednesday, Morning-Saturday, Afternoon of Tuesday and Afternoon of Wednesday. To implement this control, first I have to import this control in xmlns namespace as xmlns:controls="clr-namespace:PreferredTimeControlApp" and finally put in your page wherever you want, <Grid x:Name="LayoutRoot" Style="{StaticResource LayoutRootGridStyle}"> <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}"> <controls:PreferredTimeControl x:Name="preferredTimeControl"></controls:PreferredTimeControl> </Border> </Grid> And in the code behind you can just include this code: private void InitializeControl() { preferredTimeControl.SetAvailibility("11,12,13,16,23,22"); } And you are ready to go. For more details you can refer to my code attached. I know there can be even simpler and better way to do this. Let me know if any other ideas. Sorry, Guys Still I have used Silverlight 3 and VS2008, as from the system I am uploading this is still not upgraded, but still you can use the same code with Silverlight 4 and VS2010 without any changes. May be just it will ask you to upgrade your project which will take care of rest. Download Source Code.   Thanks ~Brij

• TFS 2010 SDK: Integrating Twitter with TFS Programmatically

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,TFS API,Integrate Twitter TFS,TFS Programming,ALM,TwitterSharp   Friends at ‘Twitter Sharp’ have created a wonderful .net API for twitter. With this blog post i will try to show you a basic TFS – Twitter integration scenario where i will retrieve the Team Project details programmatically and then publish these details on my twitter page. In future blogs i will be demonstrating how to create a windows service to capture the events raised by TFS and then publishing them in your social eco-system. Download Working Demo: Integrate Twitter - Tfs Programmatically   1. Setting up Twitter API Download Tweet Sharp from => https://github.com/danielcrenna/tweetsharp  Before you can start playing around with this, you will need to register an application on twitter. This is because Twitter uses the OAuth authentication protocol and will not issue an Access token unless your application is registered with them. Go to https://dev.twitter.com/ and register your application   Once you have registered your application, you will need ‘Customer Key’, ‘Customer Secret’, ‘Access Token’, ‘Access Token Secret’ 2. Connecting to Twitter using the Tweet Sharp API Create a new C# windows forms project and add reference to ‘Hammock.ClientProfile’, ‘Newtonsoft.Json’, ‘TweetSharp’ Add the following keys to the App.config (Note – The values for the keys below are in correct and if you try and connect using them then you will get an authorization failure error). Add a new class ‘TwitterProxy’ and use the following code to connect to the TwitterService (Read more about OAuthentication - http://dev.twitter.com/pages/auth) using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Configuration;using TweetSharp; namespace WindowsFormsApplication2{ public class TwitterProxy { private static string _hero; private static string _consumerKey; private static string _consumerSecret; private static string _accessToken; private static string _accessTokenSecret;  public static TwitterService ConnectToTwitter() { _consumerKey = ConfigurationManager.AppSettings["ConsumerKey"]; _consumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"]; _accessToken = ConfigurationManager.AppSettings["AccessToken"]; _accessTokenSecret = ConfigurationManager.AppSettings["AccessTokenSecret"];  return new TwitterService(_consumerKey, _consumerSecret, _accessToken, _accessTokenSecret); } }} Time to Tweet! _twitterService = Proxy.TwitterProxy.ConnectToTwitter(); _twitterService.SendTweet("Hello World"); SendTweet will return the TweetStatus, If you do not get a 200 OK status that means you have failed authentication, please revisit the Access tokens. --RESPONSE: https://api.twitter.com/1/statuses/update.json HTTP/1.1 200 OK X-Transaction: 1308476106-69292-41752 X-Frame-Options: SAMEORIGIN X-Runtime: 0.03040 X-Transaction-Mask: a6183ffa5f44ef11425211f25 Pragma: no-cache X-Access-Level: read-write X-Revision: DEV X-MID: bd8aa0abeccb6efba38bc0a391a73fab98e983ea Cache-Control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 Content-Type: application/json; charset=utf-8 Date: Sun, 19 Jun 2011 09:35:06 GMT Expires: Tue, 31 Mar 1981 05:00:00 GMT Last-Modified: Sun, 19 Jun 2011 09:35:06 GMT Server: hi Vary: Accept-Encoding Content-Encoding: Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Transfer-Encoding: chunked   3. Integrate with TFS In my blog post Connect to TFS Programmatically i have in depth demonstrated how to connect to TFS using the TFS API. 1: // Update the AppConfig with the URI of the Team Foundation Server you want to connect to, Make sure you have View Team Project Collection Details permissions on the server 2: private static string _myUri = ConfigurationManager.AppSettings["TfsUri"]; 3: private static TwitterService _twitterService = null; 4:   5: private void button1_Click(object sender, EventArgs e) 6: { 7: lblNotes.Text = string.Empty; 8:   9: try 10: { 11: StringBuilder notes = new StringBuilder(); 12:   13: _twitterService = Proxy.TwitterProxy.ConnectToTwitter(); 14:   15: _twitterService.SendTweet("Hello World"); 16:   17: TfsConfigurationServer configurationServer = 18: TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri)); 19:   20: CatalogNode catalogNode = configurationServer.CatalogNode; 21:   22: ReadOnlyCollection<CatalogNode> tpcNodes = catalogNode.QueryChildren( 23: new Guid[] { CatalogResourceTypes.ProjectCollection }, 24: false, CatalogQueryOptions.None); 25:   26: // tpc = Team Project Collection 27: foreach (CatalogNode tpcNode in tpcNodes) 28: { 29: Guid tpcId = new Guid(tpcNode.Resource.Properties["InstanceId"]); 30: TfsTeamProjectCollection tpc = configurationServer.GetTeamProjectCollection(tpcId); 31:   32: notes.AppendFormat("{0} Team Project Collection : {1}{0}", Environment.NewLine, tpc.Name); 33: _twitterService.SendTweet(String.Format("http://Lunartech.codeplex.com - Connecting to Team Project Collection : {0} ", tpc.Name)); 34:   35: // Get catalog of tp = 'Team Projects' for the tpc = 'Team Project Collection' 36: var tpNodes = tpcNode.QueryChildren( 37: new Guid[] { CatalogResourceTypes.TeamProject }, 38: false, CatalogQueryOptions.None); 39:   40: foreach (var p in tpNodes) 41: { 42: notes.AppendFormat("{0} Team Project : {1} - {2}{0}", Environment.NewLine, p.Resource.DisplayName,  "This is an open source project hosted on codeplex"); 43: _twitterService.SendTweet(String.Format(" Connected to Team Project: '{0}' – '{1}' ", p.Resource.DisplayName, "This is an open source project hosted on codeplex")); 44: } 45: } 46: notes.AppendFormat("{0} Updates posted on Twitter : {1} {0}", Environment.NewLine, @"http://twitter.com/lunartech1"); 47: lblNotes.Text = notes.ToString(); 48: } 49: catch (Exception ex) 50: { 51: lblError.Text = " Message : " + ex.Message + (ex.InnerException != null ?

• Memory Efficient Windows SOA Server

  - by Antony Reynolds

  Installing a Memory Efficient SOA Suite 11.1.1.6 on Windows Server Well 11.1.1.6 is now available for download so I thought I would build a Windows Server environment to run it.  I will minimize the memory footprint of the installation by putting all functionality into the Admin Server of the SOA Suite domain. Required Software 64-bit JDK SOA Suite If you want 64-bit then choose “Generic” rather than “Microsoft Windows 32bit JVM” or “Linux 32bit JVM” This has links to all the required software. If you choose “Generic” then the Repository Creation Utility link does not show, you still need this so change the platform to “Microsoft Windows 32bit JVM” or “Linux 32bit JVM” to get the software. Similarly if you need a database then you need to change the platform to get the link to XE for Windows or Linux. If possible I recommend installing a 64-bit JDK as this allows you to assign more memory to individual JVMs. Windows XE will work, but it is better if you can use a full Oracle database because of the limitations on XE that sometimes cause it to run out of space with large or multiple SOA deployments. Installation Steps The following flow chart outlines the steps required in installing and configuring SOA Suite. The steps in the diagram are explained below. 64-bit? Is a 64-bit installation required?  The Windows & Linux installers will install 32-bit versions of the Sun JDK and JRockit.  A separate JDK must be installed for 64-bit. Install 64-bit JDK The 64-bit JDK can be either Hotspot or JRockit.  You can choose either JDK 1.7 or 1.6. Install WebLogic If you are using 64-bit then install WebLogic using “java –jar wls1036_generic.jar”.  Make sure you include Coherence in the installation, the easiest way to do this is to accept the “Typical” installation. SOA Suite Required? If you are not installing SOA Suite then you can jump straight ahead and create a WebLogic domain. Install SOA Suite Run the SOA Suite installer and point it at the existing Middleware Home created for WebLogic.  Note to run the SOA installer on Windows the user must have admin privileges.  I also found that on Windows Server 2008R2 I had to start the installer from a command prompt with administrative privileges, granting it privileges when it ran caused it to ignore the jreLoc parameter. Database Available? Do you have access to a database into which you can install the SOA schema.  SOA Suite requires access to an Oracle database (it is supported on other databases but I would always use an oracle database). Install Database I use an 11gR2 Oracle database to avoid XE limitations.  Make sure that you set the database character set to be unicode (AL32UTF8).  I also disabled the new security settings because they get in the way for a developer database.  Don’t forget to check that number of processes is at least 150 and number of sessions is not set, or is set to at least 200 (in the DB init parameters). Run RCU The SOA Suite database schemas are created by running the Repository Creation Utility.  Install the “SOA and BPM Infrastructure” component to support SOA Suite.  If you keep the schema prefix as “DEV” then the config wizard is easier to complete. Run Config Wizard The Config wizard creates the domain which hosts the WebLogic server instances.  To get a minimum footprint SOA installation choose the “Oracle Enterprise Manager” and “Oracle SOA Suite for developers” products.  All other required products will be automatically selected. The “for developers” installs target the appropriate components at the AdminServer rather than creating a separate managed server to house them.  This reduces the number of JVMs required to run the system and hence the amount of memory required.  This is not suitable for anything other than a developer environment as it mixes the admin and runtime functions together in a single server.  It also takes a long time to load all the required modules, making start up a slow process. If it exists I would recommend running the config wizard found in the “oracle_common/common/bin” directory under the middleware home.  This should have access to all the templates, including SOA. If you also want to run BAM in the same JVM as everything else then you need to “Select Optional Configuration” for “Managed Servers, Clusters and Machines”. To target BAM at the AdminServer delete the “bam_server1” managed server that is created by default.  This will result in BAM being targeted at the AdminServer. Installation Issues I had a few problems when I came to test everything in my mega-JVM. Following applications were not targeted and so I needed to target them at the AdminServer: b2bui composer Healthcare UI FMW Welcome Page Application (11.1.0.0.0) How Memory Efficient is It? On a Windows 2008R2 Server running under VirtualBox I was able to bring up both the 11gR2 database and SOA/BPM/BAM in 3G memory.  I allocated a minimum 512M to the PermGen and a minimum of 1.5G for the heap.  The setting from setSOADomainEnv are shown below: set DEFAULT_MEM_ARGS=-Xms1536m -Xmx2048m set PORT_MEM_ARGS=-Xms1536m -Xmx2048m set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=512m -XX:MaxPermSize=768m set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=512m -XX:MaxPermSize=768m I arrived at these numbers by monitoring JVM memory usage in JConsole. Task Manager showed total system memory usage at 2.9G – just below the 3G I allocated to the VM. Performance is not stellar but it runs and I could run JDeveloper alongside it on my 8G laptop, so in that sense it was a result!

• Trace File Source Adapter

  The Trace File Source adapter is a useful addition to your SSIS toolbox.  It allows you to read 2005 and 2008 profiler traces stored as .trc files and read them into the Data Flow.  From there you can perform filtering and analysis using the power of SSIS. There is no need for a SQL Server connection this just uses the trace file. Example Usages Cache warming for SQL Server Analysis Services Reading the flight recorder Find out the longest running queries on a server Analyze statements for CPU, memory by user or some other criteria you choose Properties The Trace File Source adapter has two properties, both of which combine to control the source trace file that is read at runtime. SQL Server 2005 and SQL Server 2008 trace files are supported for both the Database Engine (SQL Server) and Analysis Services. The properties are managed by the Editor form or can be set directly from the Properties Grid in Visual Studio. Property Type Description AccessMode Enumeration This property determines how the Filename property is interpreted. The values available are: DirectInput Variable Filename String This property holds the path for trace file to load (*.trc). The value is either a full path, or the name of a variable which contains the full path to the trace file, depending on the AccessMode property. Trace Column Definition Hopefully the majority of you can skip this section entirely, but if you encounter some problems processing a trace file this may explain it and allow you to fix the problem. The component is built upon the trace management API provided by Microsoft. Unfortunately API methods that expose the schema of a trace file have known issues and are unreliable, put simply the data often differs from what was specified. To overcome these limitations the component uses  some simple XML files. These files enable the trace column data types and sizing attributes to be overridden. For example SQL Server Profiler or TMO generated structures define EventClass as an integer, but the real value is a string. TraceDataColumnsSQL.xml  - SQL Server Database Engine Trace Columns TraceDataColumnsAS.xml    - SQL Server Analysis Services Trace Columns The files can be found in the %ProgramFiles%\Microsoft SQL Server\100\DTS\PipelineComponents folder, e.g. "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsSQL.xml" "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsAS.xml" If at runtime the component encounters a type conversion or sizing error it is most likely due to a discrepancy between the column definition as reported by the API and the actual value encountered. Whilst most common issues have already been fixed through these files we have implemented specific exception traps to direct you to the files to enable you to fix any further issues due to different usage or data scenarios that we have not tested. An example error that you can fix through these files is shown below. Buffer exception writing value to column 'Column Name'. The string value is 999 characters in length, the column is only 111. Columns can be overridden by the TraceDataColumns XML files in "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsAS.xml". Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Trace File Source transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations. Please note that the Microsoft Trace classes used in the component are not supported on 64-bit platforms. To use the Trace File Source on a 64-bit host you need to ensure you have the 32-bit (x86) tools available, and the way you execute your package is setup to use them, please see the help topic 64-bit Considerations for Integration Services for more details.

• IBM "per core" comparisons for SPECjEnterprise2010

  - by jhenning

  I recently stumbled upon a blog entry from Roman Kharkovski (an IBM employee) comparing some SPECjEnterprise2010 results for IBM vs. Oracle. Mr. Kharkovski's blog claims that SPARC delivers half the transactions per core vs. POWER7. Prior to any argument, I should say that my predisposition is to like Mr. Kharkovski, because he says that his blog is intended to be factual; that the intent is to try to avoid marketing hype and FUD tactic; and mostly because he features a picture of himself wearing a bike helmet (me too). Therefore, in a spirit of technical argument, rather than FUD fight, there are a few areas in his comparison that should be discussed. Scaling is not free For any benchmark, if a small system scores 13k using quantity R1 of some resource, and a big system scores 57k using quantity R2 of that resource, then, sure, it's tempting to divide: is  13k/R1 > 57k/R2 ? It is tempting, but not necessarily educational. The problem is that scaling is not free. Building big systems is harder than building small systems. Scoring  13k/R1  on a little system provides no guarantee whatsoever that one can sustain that ratio when attempting to handle more than 4 times as many users. Choosing the denominator radically changes the picture When ratios are used, one can vastly manipulate appearances by the choice of denominator. In this case, lots of choices are available for the resource to be compared (R1 and R2 above). IBM chooses to put cores in the denominator. Mr. Kharkovski provides some reasons for that choice in his blog entry. And yet, it should be noted that the very concept of a core is: arbitrary: not necessarily comparable across vendors; fluid: modern chips shift chip resources in response to load; and invisible: unless you have a microscope, you can't see it. By contrast, one can actually see processor chips with the naked eye, and they are a bit easier to count. If we put chips in the denominator instead of cores, we get: 13161.07 EjOPS / 4 chips = 3290 EjOPS per chip for IBM vs 57422.17 EjOPS / 16 chips = 3588 EjOPS per chip for Oracle The choice of denominator makes all the difference in the appearance. Speaking for myself, dividing by chips just seems to make more sense, because: I can see chips and count them; and I can accurately compare the number of chips in my system to the count in some other vendor's system; and Tthe probability of being able to continue to accurately count them over the next 10 years of microprocessor development seems higher than the probability of being able to accurately and comparably count "cores". SPEC Fair use requirements Speaking as an individual, not speaking for SPEC and not speaking for my employer, I wonder whether Mr. Kharkovski's blog article, taken as a whole, meets the requirements of the SPEC Fair Use rule www.spec.org/fairuse.html section I.D.2. For example, Mr. Kharkovski's footnote (1) begins Results from http://www.spec.org as of 04/04/2013 Oracle SUN SPARC T5-8 449 EjOPS/core SPECjEnterprise2010 (Oracle's WLS best SPECjEnterprise2010 EjOPS/core result on SPARC). IBM Power730 823 EjOPS/core (World Record SPECjEnterprise2010 EJOPS/core result) The questionable tactic, from a Fair Use point of view, is that there is no such metric at the designated location. At www.spec.org, You can find the SPEC metric 57422.17 SPECjEnterprise2010 EjOPS for Oracle and You can also find the SPEC metric 13161.07 SPECjEnterprise2010 EjOPS for IBM. Despite the implication of the footnote, you will not find any mention of 449 nor anything that says 823. SPEC says that you can, under its fair use rule, derive your own values; but it emphasizes: "The context must not give the appearance that SPEC has created or endorsed the derived value." Substantiation and transparency Although SPEC disclaims responsibility for non-SPEC information (section I.E), it says that non-SPEC data and methods should be accurate, should be explained, should be substantiated. Unfortunately, it is difficult or impossible for the reader to independently verify the pricing: Were like units compared to like (e.g. list price to list price)? Were all components (hw, sw, support) included? Were all fees included? Note that when tpc.org shows IBM pricing, there are often items such as "PROCESSOR ACTIVATION" and "MEMORY ACTIVATION". Without the transparency of a detailed breakdown, the pricing claims are questionable. T5 claim for "Fastest Processor" Mr. Kharkovski several times questions Oracle's claim for fastest processor, writing You see, when you publish industry benchmarks, people may actually compare your results to other vendor's results. Well, as we performance people always say, "it depends". If you believe in performance-per-core as the primary way of looking at the world, then yes, the POWER7+ is impressive, spending its chip resources to support up to 32 threads (8 cores x 4 threads). Or, it just might be useful to consider performance-per-chip. Each SPARC T5 chip allows 128 hardware threads to be simultaneously executing (16 cores x 8 threads). The Industry Standard Benchmark that focuses specifically on processor chip performance is SPEC CPU2006. For this very well known and popular benchmark, SPARC T5: provides better performance than both POWER7 and POWER7+, for 1 chip vs. 1 chip, for 8 chip vs. 8 chip, for integer (SPECint_rate2006) and floating point (SPECfp_rate2006), for Peak tuning and for Base tuning. For example, at the 8-chip level, integer throughput (SPECint_rate2006) is: 3750 for SPARC 2170 for POWER7+. You can find the details at the March 2013 BestPerf CPU2006 page SPEC is a trademark of the Standard Performance Evaluation Corporation, www.spec.org. The two specific results quoted for SPECjEnterprise2010 are posted at the URLs linked from the discussion. Results for SPEC CPU2006 were verified at spec.org 1 July 2013, and can be rechecked here.

• ASP.NET Web Forms Extensibility: Handler Factories

  - by Ricardo Peres

  An handler factory is the class that implements IHttpHandlerFactory and is responsible for instantiating an handler (IHttpHandler) that will process the current request. This is true for all kinds of web requests, whether they are for ASPX pages, ASMX/SVC web services, ASHX/AXD handlers, or any other kind of file. Also used for restricting access for certain file types, such as Config, Csproj, etc. Handler factories are registered on the global Web.config file, normally located at %WINDIR%\Microsoft.NET\Framework<x64>\vXXXX\Config for a given path and request type (GET, POST, HEAD, etc). This goes on section <httpHandlers>. You would create a custom handler factory for a number of reasons, let me list just two: A centralized place for using dependency injection; Also a centralized place for invoking custom methods or performing some kind of validation on all pages. Let’s see an example using Unity for injecting dependencies into a page, suppose we have this on Global.asax.cs: 1: public class Global : HttpApplication 2: { 3: internal static readonly IUnityContainer Unity = new UnityContainer(); 4: 5: void Application_Start(Object sender, EventArgs e) 6: { 7: Unity.RegisterType<IFunctionality, ConcreteFunctionality>(); 8: } 9: } We instantiate Unity and register a concrete implementation for an interface, this could/should probably go in the Web.config file. Forget about its actual definition, it’s not important. Then, we create a custom handler factory: 1: public class UnityPageHandlerFactory : PageHandlerFactory 2: { 3: public override IHttpHandler GetHandler(HttpContext context, String requestType, String virtualPath, String path) 4: { 5: IHttpHandler handler = base.GetHandler(context, requestType, virtualPath, path); 6: 7: //one scenario: inject dependencies 8: Global.Unity.BuildUp(handler.GetType(), handler, String.Empty); 9:  10: return (handler); 11: } 12: } It inherits from PageHandlerFactory, which is .NET’s included factory for building regular ASPX pages. We override the GetHandler method and issue a call to the BuildUp method, which will inject required dependencies, if any exist. An example page with dependencies might be: 1: public class SomePage : Page 2: { 3: [Dependency] 4: public IFunctionality Functionality 5: { 6: get; 7: set; 8: } 9: } Notice the DependencyAttribute, it is used by Unity to identify properties that require dependency injection. When BuildUp is called, the Functionality property (or any other properties with the DependencyAttribute attribute) will receive the concrete implementation associated with it’s type, as registered on Unity. Another example, checking a page for authorization. Let’s define an interface first: 1: public interface IRestricted 2: { 3: Boolean Check(HttpContext ctx); 4: } An a page implementing that interface: 1: public class RestrictedPage : Page, IRestricted 2: { 3: public Boolean Check(HttpContext ctx) 4: { 5: //check the context and return a value 6: return ...; 7: } 8: } For this, we would use an handler factory such as this: 1: public class RestrictedPageHandlerFactory : PageHandlerFactory 2: { 3: private static readonly IHttpHandler forbidden = new UnauthorizedHandler(); 4:  5: public override IHttpHandler GetHandler(HttpContext context, String requestType, String virtualPath, String path) 6: { 7: IHttpHandler handler = base.GetHandler(context, requestType, virtualPath, path); 8: 9: if (handler is IRestricted) 10: { 11: if ((handler as IRestricted).Check(context) == false) 12: { 13: return (forbidden); 14: } 15: } 16:  17: return (handler); 18: } 19: } 20:  21: public class UnauthorizedHandler : IHttpHandler 22: { 23: #region IHttpHandler Members 24:  25: public Boolean IsReusable 26: { 27: get { return (true); } 28: } 29:  30: public void ProcessRequest(HttpContext context) 31: { 32: context.Response.StatusCode = (Int32) HttpStatusCode.Unauthorized; 33: context.Response.ContentType = "text/plain"; 34: context.Response.Write(context.Response.Status); 35: context.Response.Flush(); 36: context.Response.Close(); 37: context.ApplicationInstance.CompleteRequest(); 38: } 39:  40: #endregion 41: } The UnauthorizedHandler is an example of an IHttpHandler that merely returns an error code to the client, but does not cause redirection to the login page, it is included merely as an example. One thing we must keep in mind is, there can be only one handler factory registered for a given path/request type (verb) tuple. A typical registration would be: 1: <httpHandlers> 2: <remove path="*.aspx" verb="*"/> 3: <add path="*.aspx" verb="*" type="MyNamespace.MyHandlerFactory, MyAssembly"/> 4: </httpHandlers> First we remove the previous registration for ASPX files, and then we register our own. And that’s it. A very useful mechanism which I use lots of times.

• How do I consistently re-size my game window and elements?

  - by Milo

  In my 2D game, I have a flow layout. Inside the flow layout are tables. I have a slider that lets the user make the tables larger or smaller. This makes the background larger or smaller too. Everything should scale proportionally which means the background should stay at the same position when I make things larger, and it almost does. When the scrollbar is at 0, it does exactly this. As the scrollbar gets further down problems arise. I'll toggle the slider maybe 3 times and on the fourth time, the background jumps a little lower on the Y axis. In order to be efficient, I only start rendering the background near the parent of the flow layout. Here it is: void LobbyTableManager::renderBG( GraphicsContext* g, agui::Rectangle& absRect, agui::Rectangle& childRect ) { int cx, cy, cw, ch; g->getClippingRect(cx,cy,cw,ch); g->setClippingRect(absRect.getX(),absRect.getY(),absRect.getWidth(),absRect.getHeight()); float scale = 0.35f; int w = m_bgSprite->getWidth() * getTableScale() * scale; int h = m_bgSprite->getHeight() * getTableScale() * scale; int numX = ceil(absRect.getWidth() / (float)w) + 2; int numY = ceil(absRect.getHeight() / (float)h) + 2; float offsetX = m_activeTables[0]->getLocation().getX() - w; float offsetY = m_activeTables[0]->getLocation().getY() - h; int startY = childRect.getY(); if(moo) { std::cout << "S=" << startY << ","; } int numAttempts = 0; while(startY + h < absRect.getY() && numAttempts < 1000) { startY += h; if(moo) { std::cout << startY << ","; } numAttempts++; } if(moo) { std::cout << "\n"; moo = false; } g->holdDrawing(); for(int i = 0; i < numX; ++i) { for(int j = 0; j < numY; ++j) { g->drawScaledSprite(m_bgSprite,0,0,m_bgSprite->getWidth(),m_bgSprite->getHeight(), absRect.getX() + (i * w) + (offsetX),absRect.getY() + (j * h) + startY,w,h,0); } } g->unholdDrawing(); g->setClippingRect(cx,cy,cw,ch); } The numeric problem seems to be in the value of startY. I outputted startY figuring out its value: As you can see here, this is me only zooming in, pay attention to the final number before the next s=. You'll notice that, what should happen is, the numbers should be linear, ex: -40, -38, -36, -34, -32, -30, etc. As you'll notice, the start numbers linearly correlate ex: 62k, 64k, 66k, 68k, 70k etc.. but the end result is wrong every third or 4th time. Here is most of the resize code: void LobbyTableManager::setTableScale( float scale ) { scale += 0.3f; scale *= 2.0f; agui::Gui* gotGui = getGui(); float scrollRel = m_vScroll->getRelativeValue(); setScale(scale); rescaleTables(); resizeFlow(); if(gotGui) { gotGui->toggleWidgetLocationChanged(false); } updateScrollBars(); float newVal = scrollRel * m_vScroll->getMaxValue(); if((int)(newVal + 0.5f) > (int)newVal) { newVal++; } m_vScroll->setValue(newVal); static int x = 0; x++; moo = true; //std::cout << m_vScroll->getValue() << std::endl; if(gotGui) { gotGui->toggleWidgetLocationChanged(true); } if(gotGui) { gotGui->_widgetLocationChanged(); } } void LobbyTableManager::valueChanged( agui::VScrollBar* source,int val ) { if(getGui()) { getGui()->toggleWidgetLocationChanged(false); } m_flow->setLocation(0,-val); if(getGui()) { getGui()->toggleWidgetLocationChanged(true); getGui()->_widgetLocationChanged(); } }

• Populate a WCF syndication podcast using MP3 ID3 metadata tags

  - by brian_ritchie

  In the last post, I showed how to create a podcast using WCF syndication.  A podcast is an RSS feed containing a list of audio files to which users can subscribe.  The podcast not only contains links to the audio files, but also metadata about each episode.  A cool approach to building the feed is reading this metadata from the ID3 tags on the MP3 files used for the podcast. One library to do this is TagLib-Sharp.  Here is some sample code: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: var taggedFile = TagLib.File.Create(f); 2: var fileInfo = new FileInfo(f); 3: var item = new iTunesPodcastItem() 4: { 5: title = taggedFile.Tag.Title, 6: size = fileInfo.Length, 7: url = feed.baseUrl + fileInfo.Name, 8: duration = taggedFile.Properties.Duration, 9: mediaType = feed.mediaType, 10: summary = taggedFile.Tag.Comment, 11: subTitle = taggedFile.Tag.FirstAlbumArtist, 12: id = fileInfo.Name 13: }; 14: if (!string.IsNullOrEmpty(taggedFile.Tag.Album)) 15: item.publishedDate = DateTimeOffset.Parse(taggedFile.Tag.Album); This reads the ID3 tags into an object for later use in creating the syndication feed.  When the MP3 is created, these tags are set...or they can be set after the fact using the Properties dialog in Windows Explorer.  The only "hack" is that there isn't an easily accessible tag for "subtitle" or "published date" so I used other tags in this example. Feel free to change this to meet your purposes.  You could remove the subtitle & use the file modified data for example. That takes care of the episodes, for the feed level settings we'll load those from an XML file: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: <?xml version="1.0" encoding="utf-8" ?> 2: <iTunesPodcastFeed 3: baseUrl ="" 4: title="" 5: subTitle="" 6: description="" 7: copyright="" 8: category="" 9: ownerName="" 10: ownerEmail="" 11: mediaType="audio/mp3" 12: mediaFiles="*.mp3" 13: imageUrl="" 14: link="" 15: /> Here is the full code put together. Read the feed XML file and deserialize it into an iTunesPodcastFeed classLoop over the files in a directory reading the ID3 tags from the audio files .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static iTunesPodcastFeed CreateFeedFromFiles(string podcastDirectory, string podcastFeedFile) 2: { 3: XmlSerializer serializer = new XmlSerializer(typeof(iTunesPodcastFeed)); 4: iTunesPodcastFeed feed; 5: using (var fs = File.OpenRead(Path.Combine(podcastDirectory, podcastFeedFile))) 6: { 7: feed = (iTunesPodcastFeed)serializer.Deserialize(fs); 8: } 9: foreach (var f in Directory.GetFiles(podcastDirectory, feed.mediaFiles)) 10: { 11: try 12: { 13: var taggedFile = TagLib.File.Create(f); 14: var fileInfo = new FileInfo(f); 15: var item = new iTunesPodcastItem() 16: { 17: title = taggedFile.Tag.Title, 18: size = fileInfo.Length, 19: url = feed.baseUrl + fileInfo.Name, 20: duration = taggedFile.Properties.Duration, 21: mediaType = feed.mediaType, 22: summary = taggedFile.Tag.Comment, 23: subTitle = taggedFile.Tag.FirstAlbumArtist, 24: id = fileInfo.Name 25: }; 26: if (!string.IsNullOrEmpty(taggedFile.Tag.Album)) 27: item.publishedDate = DateTimeOffset.Parse(taggedFile.Tag.Album); 28: feed.Items.Add(item); 29: } 30: catch 31: { 32: // ignore files that can't be accessed successfully 33: } 34: } 35: return feed; 36: } Usually putting a "try...catch" like this is bad, but in this case I'm just skipping over files that are locked while they are being uploaded to the web site.Here is the code from the last couple of posts.

• Blog Buzz - Devoxx 2011

  - by Janice J. Heiss

  Some day I will make it to Devoxx – for now, I’m content to vicariously follow the blogs of attendees and pick up on what’s happening.  I’ve been doing more blog "fishing," looking for the best commentary on 2011 Devoxx. There’s plenty of food for thought – and the ideas are not half-baked.The bloggers are out in full, offering useful summaries and commentary on Devoxx goings-on.Constantin Partac, a Java developer and a member of Transylvania JUG, a community from Cluj-Napoca/Romania, offers an excellent summary of the Devoxx keynotes. Here’s a sample:“Oracle Opening Keynote and JDK 7, 8, and 9 Presentation•    Oracle is committed to Java and wants to provide support for it on any device.•    JSE 7 for Mac will be released next week.•    Oracle would like Java developers to be involved in JCP, to adopt a JSR and to attend local JUG meetings.•    JEE 7 will be released next year.•    JEE 7 is focused on cloud integration, some of the features are already implemented in glassfish 4 development branch.•    JSE 8 will be release in summer of 2013 due to “enterprise community request” as they can not keep the pace with an 18    month release cycle.•    The main features included in JSE8 are lambda support, project Jigsaw, new Date/Time API, project Coin++ and adding   support for sensors. JSE 9 probably will focus on some of these features:1.    self tuning JVM2.    improved native language integration3.    processing enhancement for big data4.    reification (adding runtime class type info for generic types)5.    unification of primitive and corresponding object classes6.    meta-object protocol in order to use type and methods define in other JVM languages7.    multi-tenancy8.    JVM resource management” Thanks Constantin! Ivan St. Ivanov, of SAP Labs Bulgaria, also commented on the keynotes with a different focus.  He summarizes Henrik Stahl’s look ahead to Java SE 8 and JavaFX 3.0; Cameron Purdy on Java EE and the cloud; celebrated Java Champion Josh Bloch on what’s good and bad about Java; Mark Reinhold’s quick look ahead to Java SE 9; and Brian Goetz on lambdas and default methods in Java SE 8. Here’s St. Ivanov’s account of Josh Bloch’s comments on the pluses of Java:“He started with the virtues of the platform. To name a few:    Tightly specified language primitives and evaluation order – int is always 32 bits and operations are executed always from left  to right, without compilers messing around    Dynamic linking – when you change a class, you need to recompile and rebuild just the jar that has it and not the whole application    Syntax  similarity with C/C++ – most existing developers at that time felt like at home    Object orientations – it was cool at that time as well as functional programming is today    It was statically typed language – helps in faster runtime, better IDE support, etc.    No operator overloading – well, I’m not sure why it is good. Scala has it for example and that’s why it is far better for defining DSLs. But I will not argue with Josh.”It’s worth checking out St. Ivanov’s summary of Bloch’s views on what’s not so great about Java as well. What's Coming in JAX-RS 2.0Marek Potociar, Principal Software Engineer at Oracle and currently specification lead of Java EE RESTful web services API (JAX-RS), blogged on his talk about what's coming in JAX-RS 2.0, scheduled for final release in mid-2012.  Here’s a taste:“Perhaps the most wanted addition to the JAX-RS is the Client API, that would complete the JAX-RS story, that is currently server-side only. In JAX-RS 2.0 we are adding a completely interface-based and fluent client API that blends nicely in with the existing fluent response builder pattern on the server-side. When we started with the client API, the first proposal contained around 30 classes. Thanks to the feedback from our Expert Group we managed to reduce the number of API classes to 14 (2 of them being exceptions)! The resulting is compact while at the same time we still managed to create an API that reflects the method invocation context flow (e.g. once you decide on the target URI and start setting headers on the request, your IDE will not try to offer you a URI setter in the code completion). This is a subtle but very important usability aspect of an API…” Obviously, Devoxx is a great Java conference, one that is hitting this year at a time when much is brewing in the platform and beginning to be anticipated.
