• Adobe Coldfusion Railo OpenBD Apache Tomcat Multiple Sites

  - by chris hough

  Here's what I am trying to do, unless I am crazy: I am trying to use Tomcat with the multiple workers, so far I got OpenBD working, but having trouble with Railo, and will be tackling Adobe after. each engine deployed as a war separated by different workers I wanted to keep both the sites and engines inside my sites directory I have to remap the symlink for the WEB-INF when I switch engines = have not found a way around this my thought is to have everything separated into modules and I want to be able to execute both cfm and php code in a single site.  Ideally, it would be amazing if there would be a way to not have to remap the symlink as well. thoughts? can this be done? I am trying to mimic how this would be setup on a live server, not using eclipse for example. here is what I am working with so far: my apache workers.properties worker.list=openbd, openbdadmin, railo, railoadmin  worker.openbd.type=ajp13  worker.openbd.host=local.mydev.openbd  worker.openbd.port=8009 worker.openbdadmin.type=ajp13  worker.openbdadmin.host=local.admin.openbd worker.openbdadmin.port=8009   worker.railo.type=ajp13  worker.railo.host=local.mydev.railo  worker.railo.port=8009 worker.railoadmin.type=ajp13  worker.railoadmin.host=local.admin.railo worker.railoadmin.port=8009   my tomcat servers.xml < Host name="local.admin.openbd" appBase="/Users/[myusername]/Websites/coldfusion.engines"  unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false"        < Context path="" docBase="openbd/" reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host        < Host name="local.admin.railo"   appBase="/Users/[my username]/Websites/coldfusion.engines" unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false"        < Context path="" docBase="railo/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host < Host name="local.mydev.openbd"   appBase="/Users/[my username]/Websites/coldfusion.engines" unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false" < Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true"< /Context < /Host < Host name="local.mydev.railo"   appBase="/Users/[my username]/Websites/coldfusion.engines"  unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false" < Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host my apache vhosts ServerName local.admin.openbd DocumentRoot /Users/[my username]/Websites/coldfusion.engines/openBD/ #Mount OpenBD and tell it to only server cfml files JkMount /*.cfm openbdadmin ErrorLog "/Users/[my username]/Websites/apache.logs/local_openbdadmin_error.log" ServerName local.admin.railo DocumentRoot /Users/[my username]/Websites/coldfusion.engines/railo/ #Mount Railo and tell it to only server cfml files JkMount /*.cfm railoadmin ErrorLog "/Users/[my username]/Websites/apache.logs/local_railoadmin_error.log" ServerName local.mydev DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_error.log" ServerName local.mydev.openbd DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot #Mount OpenBD and tell it to only server cfml files JkMount /*.cfm openbd ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_openbd_error.log" ServerName local.mydev.railo DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot JkMount /*.cfm railo ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_railo_error.log" my folder structure I am using websites/apache.logs/ websites/coldfusion.engines/ websites/coldfusion.engines/cfusion/ websites/coldfusion.engines/openBD/ websites/coldfusion.engines/railo/ websites/example.mydev/ websites/example.mydev/wwwroot/ websites/example.mydev/wwwroot/index.cfm   websites/example.mydev/wwwroot/index.htm   websites/example.mydev/wwwroot/index.php   error log output [Thu Aug 27 00:54:50.443 2009] [11279:2686719776] [info] init_jk::mod_jk.c (3183): mod_jk/1.2.28 initialized [Thu Aug 27 00:54:51.346 2009] [11280:2686719776] [info] init_jk::mod_jk.c (3183): mod_jk/1.2.28 initialized [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [info] jk_open_socket::jk_connect.c (594): connect to 127.0.0.1:8009 failed (errno=61) [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [info] ajp_connect_to_endpoint::jk_ajp_common.c (922): Failed opening socket to (127.0.0.1:8009) (errno=61) [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [error] ajp_send_request::jk_ajp_common.c (1507): (openbdadmin) connecting to backend failed.

• ASP.NET Asynchronous Pages and when to use them

  - by rajbk

  There have been several articles posted about using  asynchronous pages in ASP.NET but none of them go into detail as to when you should use them. I finally found a great post by Thomas Marquardt that explains the process in depth. He addresses a key misconception also: So, in your ASP.NET application, when should you perform work asynchronously instead of synchronously? Well, only 1 thread per CPU can execute at a time.  Did you catch that?  A lot of people seem to miss this point...only one thread executes at a time on a CPU. When you have more than this, you pay an expensive penalty--a context switch. However, if a thread is blocked waiting on work...then it makes sense to switch to another thread, one that can execute now.  It also makes sense to switch threads if you want work to be done in parallel as opposed to in series, but up until a certain point it actually makes much more sense to execute work in series, again, because of the expensive context switch. Pop quiz: If you have a thread that is doing a lot of computational work and using the CPU heavily, and this takes a while, should you switch to another thread? No! The current thread is efficiently using the CPU, so switching will only incur the cost of a context switch. Ok, well, what if you have a thread that makes an HTTP or SOAP request to another server and takes a long time, should you switch threads? Yes! You can perform the HTTP or SOAP request asynchronously, so that once the "send" has occurred, you can unwind the current thread and not use any threads until there is an I/O completion for the "receive". Between the "send" and the "receive", the remote server is busy, so locally you don't need to be blocking on a thread, but instead make use of the asynchronous APIs provided in .NET Framework so that you can unwind and be notified upon completion. Again, it only makes sense to switch threads if the benefit from doing so out weights the cost of the switch. Read more about it in these posts: Performing Asynchronous Work, or Tasks, in ASP.NET Applications http://blogs.msdn.com/tmarq/archive/2010/04/14/performing-asynchronous-work-or-tasks-in-asp-net-applications.aspx ASP.NET Thread Usage on IIS 7.0 and 6.0 http://blogs.msdn.com/tmarq/archive/2007/07/21/asp-net-thread-usage-on-iis-7-0-and-6-0.aspx   PS: I generally do not write posts that simply link to other posts but think it is warranted in this case.

• WLS MBeans

  - by Jani Rautiainen

  WLS provides a set of Managed Beans (MBeans) to configure, monitor and manage WLS resources. We can use the WLS MBeans to automate some of the tasks related to the configuration and maintenance of the WLS instance. The MBeans can be accessed a number of ways; using various UIs and programmatically using Java or WLST Python scripts.For customization development we can use the features to e.g. manage the deployed customization in MDS, control logging levels, automate deployment of dependent libraries etc. This article is an introduction on how to access and use the WLS MBeans. The goal is to illustrate the various access methods in a single article; the details of the features are left to the linked documentation.This article covers Windows based environment, steps for Linux would be similar however there would be some differences e.g. on how the file paths are defined. MBeansThe WLS MBeans can be categorized to runtime and configuration MBeans.The Runtime MBeans can be used to access the runtime information about the server and its resources. The data from runtime beans is only available while the server is running. The runtime beans can be used to e.g. check the state of the server or deployment.The Configuration MBeans contain information about the configuration of servers and resources. The configuration of the domain is stored in the config.xml file and the configuration MBeans can be used to access and modify the configuration data. For more information on the WLS MBeans refer to: Understanding WebLogic Server MBeans WLS MBean reference Java Management Extensions (JMX)We can use JMX APIs to access the WLS MBeans. This allows us to create Java programs to configure, monitor, and manage WLS resources. In order to use the WLS MBeans we need to add the following library into the class-path: WL_HOME\lib\wljmxclient.jar Connecting to a WLS MBean server The WLS MBeans are contained in a Mbean server, depending on the requirement we can connect to (MBean Server / JNDI Name): Domain Runtime MBean Server weblogic.management.mbeanservers.domainruntime Runtime MBean Server weblogic.management.mbeanservers.runtime Edit MBean Server weblogic.management.mbeanservers.edit To connect to the WLS MBean server first we need to create a map containing the credentials; Hashtable<String, String> param = new Hashtable<String, String>(); param.put(Context.SECURITY_PRINCIPAL, "weblogic");        param.put(Context.SECURITY_CREDENTIALS, "weblogic1");        param.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES, "weblogic.management.remote"); These define the user, password and package containing the protocol. Next we create the connection: JMXServiceURL serviceURL =     new JMXServiceURL("t3","127.0.0.1",7101,     "/jndi/weblogic.management.mbeanservers.domainruntime"); JMXConnector connector = JMXConnectorFactory.connect(serviceURL, param); MBeanServerConnection connection = connector.getMBeanServerConnection(); With the connection we can now access the MBeans for the WLS instance. For a complete example see Appendix A of this post. For more details refer to Accessing WebLogic Server MBeans with JMX Accessing WLS MBeans The WLS MBeans are structured hierarchically; in order to access content we need to know the path to the MBean we are interested in. The MBean is accessed using “MBeanServerConnection. getAttribute” API.  WLS provides entry points to the hierarchy allowing us to navigate all the WLS MBeans in the hierarchy (MBean Server / JMX object name): Domain Runtime MBean Server com.bea:Name=DomainRuntimeService,Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean Runtime MBean Servers com.bea:Name=RuntimeService,Type=weblogic.management.mbeanservers.runtime.RuntimeServiceMBean Edit MBean Server com.bea:Name=EditService,Type=weblogic.management.mbeanservers.edit.EditServiceMBean For example we can access the Domain Runtime MBean using: ObjectName service = new ObjectName( "com.bea:Name=DomainRuntimeService," + "Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean"); Same syntax works for any “child” WLS MBeans e.g. to find out all application deployments we can: ObjectName domainConfig = (ObjectName)connection.getAttribute(service,"DomainConfiguration"); ObjectName[] appDeployments = (ObjectName[])connection.getAttribute(domainConfig,"AppDeployments"); Alternatively we could access the same MBean using the full syntax: ObjectName domainConfig = new ObjectName("com.bea:Location=DefaultDomain,Name=DefaultDomain,Type=Domain"); ObjectName[] appDeployments = (ObjectName[])connection.getAttribute(domainConfig,"AppDeployments"); For more details refer to Accessing WebLogic Server MBeans with JMX Invoking operations on WLS MBeans The WLS MBean operations can be invoked with MBeanServerConnection. invoke API; in the following example we query the state of “AppsLoggerService” application: ObjectName appRuntimeStateRuntime = new ObjectName("com.bea:Name=AppRuntimeStateRuntime,Type=AppRuntimeStateRuntime"); Object[] parameters = { "AppsLoggerService", "DefaultServer" }; String[] signature = { "java.lang.String", "java.lang.String" }; String result = (String)connection.invoke(appRuntimeStateRuntime,"getCurrentState",parameters, signature); The result returned should be "STATE_ACTIVE" assuming the "AppsLoggerService" application is up and running. WebLogic Scripting Tool (WLST) The WebLogic Scripting Tool (WLST) is a command-line scripting environment that we can access the same WLS MBeans. The tool is located under: $MW_HOME\oracle_common\common\bin\wlst.bat Do note that there are several instances of the wlst script under the $MW_HOME, each of them works, however the commands available vary, so we want to use the one under “oracle_common”. The tool is started in offline mode. In offline mode we can access and manipulate the domain configuration. In online mode we can access the runtime information. We connect to the Administration Server : connect("weblogic","weblogic1", "t3://127.0.0.1:7101") In both online and offline modes we can navigate the WLS MBean using commands like "ls" to print content and "cd" to navigate between objects, for example: All the commands available can be obtained with: help('all') For details of the tool refer to WebLogic Scripting Tool and for the commands available WLST Command and Variable Reference. Also do note that the WLST tool can be invoked from Java code in Embedded Mode. Running Scripts The WLST tool allows us to automate tasks using Python scripts in Script Mode. The script can be manually created or recorded by the WLST tool. Example commands of recording a script: startRecording("c:/temp/recording.py") <commands that we want to record> stopRecording() We can run the script from WLST: execfile("c:/temp/recording.py") We can also run the script from the command line: C:\apps\Oracle\Middleware\oracle_common\common\bin\wlst.cmd c:/temp/recording.py There are various sample scripts are provided with the WLS instance. UI to Access the WLS MBeans There are various UIs through which we can access the WLS MBeans. Oracle Enterprise Manager Fusion Middleware Control Oracle WebLogic Server Administration Console Fusion Middleware Control MBean Browser In the integrated JDeveloper environment only the Oracle WebLogic Server Administration Console is available to us. For more information refer to the documentation, one noteworthy feature in the console is the ability to record WLST scripts based on the navigation. In addition to the UIs above the JConsole included in the JDK can be used to access the WLS MBeans. The JConsole needs to be started with specific parameter to force WLS objects to be used and jar files in the classpath: "C:\apps\Oracle\Middleware\jdk160_24\bin\jconsole" -J-Djava.class.path=C:\apps\Oracle\Middleware\jdk160_24\lib\jconsole.jar;C:\apps\Oracle\Middleware\jdk160_24\lib\tools.jar;C:\apps\Oracle\Middleware\wlserver_10.3\server\lib\wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote For more details refer to the Accessing Custom MBeans from JConsole. Summary In this article we have covered various ways we can access and use the WLS MBeans in context of integrated WLS in JDeveloper to be used for Fusion Application customization development.

• What's a good way to organize samplers for HLSL?

  - by Rei Miyasaka

  According to MSDN, I can have 4096 samplers per context. That's a lot, considering there's only a handful of common sampler states. That tempts me to initialize an array containing a whole bunch of common sampler states, assign them to every device context I use, and then in the pixel shaders refer to them by index using : register(s[n]) where n is the index in the array. If I want more samplers for whatever reason, I can just add them on after the last slot. Does this work? If not, when should I set the samplers? Should it be done when by the mesh renderer? The texture renderer? Or alongside PSSetShader? Edit: That trick I wrote above doesn't work (at least not yet), as the compiler gives me this error message when I try to use the same register twice: error X4500: overlapping register semantics not yet implemented 's0' So how do people usually organize samplers, then?

  Apress books Visual C# 2010 (ISBN 978-1-4302-3171-4) - http://www.apress.com/book/view/1430231718 is both an excellent introduction to C# programming and a manual for those with experiance. So far I have only been through a few chapters but I have been favourably impressed. In the chapter on Exceptions, I have posted an errata regarding the custom exception in  listing 14-17; it is missing an overload required by FXCOP     private CustomException(SerializationInfo info, StreamingContext context) : base(info, context)     {     } Aside of this minor point, I have no hesitation to recommending this book to anyone who wishes to learn C#.

• HTTP Basic Auth Protected Services using Web Service Data Control

  - by vishal.s.jain(at)oracle.com

  With Oracle JDeveloper 11g (11.1.1.4.0) one can now create Web Service Data Control for services which are protected with HTTP Basic Authentication.So when you provide such a service to the Data Control Wizard, a dialog pops up prompting you to entry the authentication details:After you give the details, you can proceed with the creation of Data Control.Once the Data Control is created, you can use the WSDC Tester to quickly test the service.In this case, since the service is protected, we need to first edit the connection to provide username details:Enter the authentication details against username and password. Once done, select DataControl.dcx and using the context menu, select 'Run'. This will bring up the Tester.On the Tester, select the Service Node and using context menu pick 'Operations'. This will bring up the methods which you can test:Now you can pick a method, provide the input parameters and hit execute to see the results.

• Who Are the BI Users in Your Neighborhood?

  - by Brian Dayton

  Forrester's Boris Evelson recently wrote a blog titled "Who are the BI Personas?" that I enjoyed for a number of reasons. It's a quick read, easy to grasp and (refreshingly) focuses on the users of technology VS the technology. As Evelson admits, he meant to keep the reference chart at a high-level because there are too many different permutations and additional sub-categories to make such a chart useful. For me, I wouldn't head into the technical permutations but more the contextual use of BI and the issues that users experience.  My thoughts brought up more questions than answers such as: Context: -          HOW: With the exception of the "Power User" persona--likely some sort of business or operations analyst? -          WHEN: Are they using the information to make real-time decisions on the front lines (a customer service manager or shipping/logistics VP) or are they using this information for cumulative analysis and business planning? Or both? -          WHERE: What areas of the business are more or less likely to rely on BI across an organization? Human Resources, Operations, Facilities, Finance--- and why are some more prone to use data-driven analysis than others? Issues: -          DELAYS & DRAG ON IT?: One of the persona characteristics Evelson calls out is a reliance on IT. Every persona except for the "Power User" has a heavy reliance on IT for support. What business issues or delays does that cause to users? What is the drag on IT resources who could potentially be creating instead of reporting? -          HOW MANY CLICKS: If BI is being used within the context of a transaction (sales manager looking for upsell opportunities as an example) is that person getting the information within the context of that action or transaction? Or are they minimizing screens, logging into another application or reporting tool, running queries, etc.?   Who are the BI Users in your neighborhood or line of business? Do Evelson's personas resonate--and do the tools that he calls out (he refers to it as "BI Style") resonate with what your personas have or need? Finally, I'm very interested if BI use is viewed as  a bolt-on...or an integrated part of your daily enterprise processes?

• A C# implementation of the CallStream pattern

  - by Bertrand Le Roy

  Dusan published this interesting post a couple of weeks ago about a novel JavaScript chaining pattern: http://dbj.org/dbj/?p=514 It’s similar to many existing patterns, but the syntax is extraordinarily terse and it provides a new form of friction-free, plugin-less extensibility mechanism. Here’s a JavaScript example from Dusan’s post: CallStream("#container") (find, "div") (attr, "A", 1) (css, "color", "#fff") (logger); The interesting thing here is that the functions that are being passed as the first argument are arbitrary, they don’t need to be declared as plug-ins. Compare that with a rough jQuery equivalent that could look something like this: $.fn.logger = function () { /* ... */ } $("selector") .find("div") .attr("A", 1) .css("color", "#fff") .logger(); There is also the “each” method in jQuery that achieves something similar, but its syntax is a little more verbose. Of course, that this pattern can be expressed so easily in JavaScript owes everything to the extraordinary way functions are treated in that language, something Douglas Crockford called “the very best part of JavaScript”. One of the first things I thought while reading Dusan’s post was how I could adapt that to C#. After all, with Lambdas and delegates, C# also has its first-class functions. And sure enough, it works really really well. After about ten minutes, I was able to write this: CallStreamFactory.CallStream (p => Console.WriteLine("Yay!")) (Dump, DateTime.Now) (DumpFooAndBar, new { Foo = 42, Bar = "the answer" }) (p => Console.ReadKey()); Where the Dump function is: public static void Dump(object options) { Console.WriteLine(options.ToString()); } And DumpFooAndBar is: public static void DumpFooAndBar(dynamic options) { Console.WriteLine("Foo is {0} and bar is {1}.", options.Foo, options.Bar); } So how does this work? Well, it really is very simple. And not. Let’s say it’s not a lot of code, but if you’re like me you might need an Advil after that. First, I defined the signature of the CallStream method as follows: public delegate CallStream CallStream (Action<object> action, object options = null); The delegate define a call stream as something that takes an action (a function of the options) and an optional options object and that returns a delegate of its own type. Tricky, but that actually works, a delegate can return its own type. Then I wrote an implementation of that delegate that calls the action and returns itself: public static CallStream CallStream (Action<object> action, object options = null) { action(options); return CallStream; } Pretty nice, eh? Well, yes and no. What we are doing here is to execute a sequence of actions using an interesting novel syntax. But for this to be actually useful, you’d need to build a more specialized call stream factory that comes with some sort of context (like Dusan did in JavaScript). For example, you could write the following alternate delegate signature that takes a string and returns itself: public delegate StringCallStream StringCallStream(string message); And then write the following call stream (notice the currying): public static StringCallStream CreateDumpCallStream(string dumpPath) { StringCallStream str = null; var dump = File.AppendText(dumpPath); dump.AutoFlush = true; str = s => { dump.WriteLine(s); return str; }; return str; } (I know, I’m not closing that stream; sure; bad, bad Bertrand) Finally, here’s how you use it: CallStreamFactory.CreateDumpCallStream(@".\dump.txt") ("Wow, this really works.") (DateTime.Now.ToLongTimeString()) ("And that is all."); Next step would be to combine this contextual implementation with the one that takes an action parameter and do some really fun stuff. I’m only scratching the surface here. This pattern could reveal itself to be nothing more than a gratuitous mind-bender or there could be applications that we hardly suspect at this point. In any case, it’s a fun new construct. Or is this nothing new? You tell me… Comments are open :)

• Entity Framework Batch Update and Future Queries

  - by pwelter34

  Entity Framework Extended Library A library the extends the functionality of Entity Framework. Features Batch Update and Delete Future Queries Audit Log Project Package and Source NuGet Package PM> Install-Package EntityFramework.Extended NuGet: http://nuget.org/List/Packages/EntityFramework.Extended Source: http://github.com/loresoft/EntityFramework.Extended Batch Update and Delete A current limitations of the Entity Framework is that in order to update or delete an entity you have to first retrieve it into memory. Now in most scenarios this is just fine. There are however some senerios where performance would suffer. Also, for single deletes, the object must be retrieved before it can be deleted requiring two calls to the database. Batch update and delete eliminates the need to retrieve and load an entity before modifying it. Deleting //delete all users where FirstName matches context.Users.Delete(u => u.FirstName == "firstname"); Update //update all tasks with status of 1 to status of 2 context.Tasks.Update( t => t.StatusId == 1, t => new Task {StatusId = 2}); //example of using an IQueryable as the filter for the update var users = context.Users .Where(u => u.FirstName == "firstname"); context.Users.Update( users, u => new User {FirstName = "newfirstname"}); Future Queries Build up a list of queries for the data that you need and the first time any of the results are accessed, all the data will retrieved in one round trip to the database server. Reducing the number of trips to the database is a great. Using this feature is as simple as appending .Future() to the end of your queries. To use the Future Queries, make sure to import the EntityFramework.Extensions namespace. Future queries are created with the following extension methods... Future() FutureFirstOrDefault() FutureCount() Sample // build up queries var q1 = db.Users .Where(t => t.EmailAddress == "[email protected]") .Future(); var q2 = db.Tasks .Where(t => t.Summary == "Test") .Future(); // this triggers the loading of all the future queries var users = q1.ToList(); In the example above, there are 2 queries built up, as soon as one of the queries is enumerated, it triggers the batch load of both queries. // base query var q = db.Tasks.Where(t => t.Priority == 2); // get total count var q1 = q.FutureCount(); // get page var q2 = q.Skip(pageIndex).Take(pageSize).Future(); // triggers execute as a batch int total = q1.Value; var tasks = q2.ToList(); In this example, we have a common senerio where you want to page a list of tasks. In order for the GUI to setup the paging control, you need a total count. With Future, we can batch together the queries to get all the data in one database call. Future queries work by creating the appropriate IFutureQuery object that keeps the IQuerable. The IFutureQuery object is then stored in IFutureContext.FutureQueries list. Then, when one of the IFutureQuery objects is enumerated, it calls back to IFutureContext.ExecuteFutureQueries() via the LoadAction delegate. ExecuteFutureQueries builds a batch query from all the stored IFutureQuery objects. Finally, all the IFutureQuery objects are updated with the results from the query. Audit Log The Audit Log feature will capture the changes to entities anytime they are submitted to the database. The Audit Log captures only the entities that are changed and only the properties on those entities that were changed. The before and after values are recorded. AuditLogger.LastAudit is where this information is held and there is a ToXml() method that makes it easy to turn the AuditLog into xml for easy storage. The AuditLog can be customized via attributes on the entities or via a Fluent Configuration API. Fluent Configuration // config audit when your application is starting up... var auditConfiguration = AuditConfiguration.Default; auditConfiguration.IncludeRelationships = true; auditConfiguration.LoadRelationships = true; auditConfiguration.DefaultAuditable = true; // customize the audit for Task entity auditConfiguration.IsAuditable<Task>() .NotAudited(t => t.TaskExtended) .FormatWith(t => t.Status, v => FormatStatus(v)); // set the display member when status is a foreign key auditConfiguration.IsAuditable<Status>() .DisplayMember(t => t.Name); Create an Audit Log var db = new TrackerContext(); var audit = db.BeginAudit(); // make some updates ... db.SaveChanges(); var log = audit.LastLog;

• Playing with aspx page cycle using JustMock

  - by mehfuzh

  In this post , I will cover a test code that will mock the various elements needed to complete a HTTP page request and  assert the expected page cycle steps. To begin, i have a simple enumeration that has my predefined page steps: public enum PageStep {     PreInit,     Load,     PreRender,     UnLoad } Once doing so, i  first created the page object [not mocking]. Page page = new Page(); Here, our target is to fire up the page process through ProcessRequest call, now if we take a look inside the method with reflector.net,  the call trace will go like : ProcessRequest –> ProcessRequestWithNoAssert –> SetInstrinsics –> Finallly ProcessRequest. Inside SetInstrinsics ,  it requires calls from HttpRequest, HttpResponse and HttpBrowserCababilities. Using this clue at hand, we can easily know the classes / calls  we need to mock in order to get through the expected call. Accordingly, for  HttpBrowserCapabilities our required mock code will look like: var browser = Mock.Create<HttpBrowserCapabilities>(); // Arrange Mock.Arrange(() => browser.PreferredRenderingMime).Returns("text/html"); Mock.Arrange(() => browser.PreferredResponseEncoding).Returns("UTF-8"); Mock.Arrange(() => browser.PreferredRequestEncoding).Returns("UTF-8"); Now, HttpBrowserCapabilities is get though [Instance]HttpRequest.Browser. Therefore, we create the HttpRequest mock: var request = Mock.Create<HttpRequest>(); Then , add the required get call : Mock.Arrange(() => request.Browser).Returns(browser); As, [instance]Browser.PerferrredResponseEncoding and [instance]Browser.PreferredResponseEncoding  are also set to the request object and to make that they are set properly, we can add the following lines as well [not required though]. bool requestContentEncodingSet = false; Mock.ArrangeSet(() => request.ContentEncoding = Encoding.GetEncoding("UTF-8")).DoInstead(() =>  requestContentEncodingSet = true); Similarly, for response we can write:  var response = Mock.Create<HttpResponse>();    bool responseContentEncodingSet = false;  Mock.ArrangeSet(() => response.ContentEncoding = Encoding.GetEncoding("UTF-8")).DoInstead(() => responseContentEncodingSet = true); Finally , I created a mock of HttpContext and set the Request and Response properties that will returns the mocked version. var context = Mock.Create<HttpContext>();   Mock.Arrange(() => context.Request).Returns(request); Mock.Arrange(() => context.Response).Returns(response); As, Page internally calls RenderControl method , we just need to replace that with our one and optionally we can check if  invoked properly: bool rendered = false; Mock.Arrange(() => page.RenderControl(Arg.Any<HtmlTextWriter>())).DoInstead(() => rendered = true); That’s  it, the rest of the code is simple,  where  i asserted the page cycle with the PageSteps that i defined earlier: var pageSteps = new Queue<PageStep>();   page.PreInit +=delegate { pageSteps.Enqueue(PageStep.PreInit); }; page.Load += delegate { pageSteps.Enqueue(PageStep.Load); }; page.PreRender += delegate { pageSteps.Enqueue(PageStep.PreRender);}; page.Unload +=delegate { pageSteps.Enqueue(PageStep.UnLoad);};   page.ProcessRequest(context);   Assert.True(requestContentEncodingSet); Assert.True(responseContentEncodingSet); Assert.True(rendered);   Assert.Equal(pageSteps.Dequeue(), PageStep.PreInit); Assert.Equal(pageSteps.Dequeue(), PageStep.Load); Assert.Equal(pageSteps.Dequeue(), PageStep.PreRender); Assert.Equal(pageSteps.Dequeue(), PageStep.UnLoad);   Mock.Assert(request); Mock.Assert(response); You can get the test class shown in this post here to give a try by yourself with of course JustMock :-). Enjoy!!

• 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!

• Do Not Optimize Without Measuring

  - by Alois Kraus

  Recently I had to do some performance work which included reading a lot of code. It is fascinating with what ideas people come up to solve a problem. Especially when there is no problem. When you look at other peoples code you will not be able to tell if it is well performing or not by reading it. You need to execute it with some sort of tracing or even better under a profiler. The first rule of the performance club is not to think and then to optimize but to measure, think and then optimize. The second rule is to do this do this in a loop to prevent slipping in bad things for too long into your code base. If you skip for some reason the measure step and optimize directly it is like changing the wave function in quantum mechanics. This has no observable effect in our world since it does represent only a probability distribution of all possible values. In quantum mechanics you need to let the wave function collapse to a single value. A collapsed wave function has therefore not many but one distinct value. This is what we physicists call a measurement. If you optimize your application without measuring it you are just changing the probability distribution of your potential performance values. Which performance your application actually has is still unknown. You only know that it will be within a specific range with a certain probability. As usual there are unlikely values within your distribution like a startup time of 20 minutes which should only happen once in 100 000 years. 100 000 years are a very short time when the first customer tries your heavily distributed networking application to run over a slow WIFI network… What is the point of this? Every programmer/architect has a mental performance model in his head. A model has always a set of explicit preconditions and a lot more implicit assumptions baked into it. When the model is good it will help you to think of good designs but it can also be the source of problems. In real world systems not all assumptions of your performance model (implicit or explicit) hold true any longer. The only way to connect your performance model and the real world is to measure it. In the WIFI example the model did assume a low latency high bandwidth LAN connection. If this assumption becomes wrong the system did have a drastic change in startup time. Lets look at a example. Lets assume we want to cache some expensive UI resource like fonts objects. For this undertaking we do create a Cache class with the UI themes we want to support. Since Fonts are expensive objects we do create it on demand the first time the theme is requested. A simple example of a Theme cache might look like this: using System; using System.Collections.Generic; using System.Drawing; struct Theme { public Color Color; public Font Font; } static class ThemeCache { static Dictionary<string, Theme> _Cache = new Dictionary<string, Theme> { {"Default", new Theme { Color = Color.AliceBlue }}, {"Theme12", new Theme { Color = Color.Aqua }}, }; public static Theme Get(string theme) { Theme cached = _Cache[theme]; if (cached.Font == null) { Console.WriteLine("Creating new font"); cached.Font = new Font("Arial", 8); } return cached; } } class Program { static void Main(string[] args) { Theme item = ThemeCache.Get("Theme12"); item = ThemeCache.Get("Theme12"); } } This cache does create font objects only once since on first retrieve of the Theme object the font is added to the Theme object. When we let the application run it should print “Creating new font” only once. Right? Wrong! The vigilant readers have spotted the issue already. The creator of this cache class wanted to get maximum performance. So he decided that the Theme object should be a value type (struct) to not put too much pressure on the garbage collector. The code Theme cached = _Cache[theme]; if (cached.Font == null) { Console.WriteLine("Creating new font"); cached.Font = new Font("Arial", 8); } does work with a copy of the value stored in the dictionary. This means we do mutate a copy of the Theme object and return it to our caller. But the original Theme object in the dictionary will have always null for the Font field! The solution is to change the declaration of struct Theme to class Theme or to update the theme object in the dictionary. Our cache as it is currently is actually a non caching cache. The funny thing was that I found out with a profiler by looking at which objects where finalized. I found way too many font objects to be finalized. After a bit debugging I found the allocation source for Font objects was this cache. Since this cache was there for years it means that the cache was never needed since I found no perf issue due to the creation of font objects. the cache was never profiled if it did bring any performance gain. to make the cache beneficial it needs to be accessed much more often. That was the story of the non caching cache. Next time I will write something something about measuring.

• assigning values to shader parameters in the XNA content pipeline

  - by Nick

  I have tried creating a simple content processor that assigns the custom effect I created to models instead of the default BasicEffect. [ContentProcessor(DisplayName = "Shadow Mapping Model")] public class ShadowMappingModelProcessor : ModelProcessor { protected override MaterialContent ConvertMaterial(MaterialContent material, ContentProcessorContext context) { EffectMaterialContent shadowMappingMaterial = new EffectMaterialContent(); shadowMappingMaterial.Effect = new ExternalReference<EffectContent>("Effects/MultipassShadowMapping.fx"); return context.Convert<MaterialContent, MaterialContent>(shadowMappingMaterial, typeof(MaterialProcessor).Name); } } This works, but when I go to draw a model in a game, the effect has no material properties assigned. How would I go about assigning, say, my DiffuseColor or SpecularColor shader parameter to white or (better) can I assign it to some value specified by the artist in the model? (I think this may have something to do with the OpaqueDataDictionary but I am confused on how to use it--the content pipeline has always been a black box to me.)

• Unable to cast transparent proxy to type &lt;type&gt;

  - by Rick Strahl

  This is not the first time I've run into this wonderful error while creating new AppDomains in .NET and then trying to load types and access them across App Domains. In almost all cases the problem I've run into with this error the problem comes from the two AppDomains involved loading different copies of the same type. Unless the types match exactly and come exactly from the same assembly the typecast will fail. The most common scenario is that the types are loaded from different assemblies - as unlikely as that sounds. An Example of Failure To give some context, I'm working on some old code in Html Help Builder that creates a new AppDomain in order to parse assembly information for documentation purposes. I create a new AppDomain in order to load up an assembly process it and then immediately unload it along with the AppDomain. The AppDomain allows for unloading that otherwise wouldn't be possible as well as isolating my code from the assembly that's being loaded. The process to accomplish this is fairly established and I use it for lots of applications that use add-in like functionality - basically anywhere where code needs to be isolated and have the ability to be unloaded. My pattern for this is: Create a new AppDomain Load a Factory Class into the AppDomain Use the Factory Class to load additional types from the remote domain Here's the relevant code from my TypeParserFactory that creates a domain and then loads a specific type - TypeParser - that is accessed cross-AppDomain in the parent domain:public class TypeParserFactory : System.MarshalByRefObject,IDisposable { …/// <summary> /// TypeParser Factory method that loads the TypeParser /// object into a new AppDomain so it can be unloaded. /// Creates AppDomain and creates type. /// </summary> /// <returns></returns> public TypeParser CreateTypeParser() { if (!CreateAppDomain(null)) return null; /// Create the instance inside of the new AppDomain /// Note: remote domain uses local EXE's AppBasePath!!! TypeParser parser = null; try { Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); } catch (Exception ex) { this.ErrorMessage = ex.GetBaseException().Message; return null; } return parser; } private bool CreateAppDomain(string lcAppDomain) { if (lcAppDomain == null) lcAppDomain = "wwReflection" + Guid.NewGuid().ToString().GetHashCode().ToString("x"); AppDomainSetup setup = new AppDomainSetup(); // *** Point at current directory setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; //setup.PrivateBinPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin"); this.LocalAppDomain = AppDomain.CreateDomain(lcAppDomain,null,setup); // Need a custom resolver so we can load assembly from non current path AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve); return true; } …} Note that the classes must be either [Serializable] (by value) or inherit from MarshalByRefObject in order to be accessible remotely. Here I need to call methods on the remote object so all classes are MarshalByRefObject. The specific problem code is the loading up a new type which points at an assembly that visible both in the current domain and the remote domain and then instantiates a type from it. This is the code in question:Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); The last line of code is what blows up with the Unable to cast transparent proxy to type <type> error. Without the cast the code actually returns a TransparentProxy instance, but the cast is what blows up. In other words I AM in fact getting a TypeParser instance back but it can't be cast to the TypeParser type that is loaded in the current AppDomain. Finding the Problem To see what's going on I tried using the .NET 4.0 dynamic type on the result and lo and behold it worked with dynamic - the value returned is actually a TypeParser instance: Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; object objparser = this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); // dynamic works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // casting fails parser = (TypeParser)objparser; So clearly a TypeParser type is coming back, but nevertheless it's not the right one. Hmmm… mysterious.Another couple of tries reveal the problem however:// works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // c:\wwapps\wwhelp\wwReflection20.dll (Current Execution Folder) string info3 = typeof(TypeParser).Assembly.CodeBase; // c:\program files\vfp9\wwReflection20.dll (my COM client EXE's folder) string info4 = dynParser.GetType().Assembly.CodeBase; // fails parser = (TypeParser)objparser; As you can see the second value is coming from a totally different assembly. Note that this is even though I EXPLICITLY SPECIFIED an assembly path to load the assembly from! Instead .NET decided to load the assembly from the original ApplicationBase folder. Ouch! How I actually tracked this down was a little more tedious: I added a method like this to both the factory and the instance types and then compared notes:public string GetVersionInfo() { return ".NET Version: " + Environment.Version.ToString() + "\r\n" + "wwReflection Assembly: " + typeof(TypeParserFactory).Assembly.CodeBase.Replace("file:///", "").Replace("/", "\\") + "\r\n" + "Assembly Cur Dir: " + Directory.GetCurrentDirectory() + "\r\n" + "ApplicationBase: " + AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "\r\n" + "App Domain: " + AppDomain.CurrentDomain.FriendlyName + "\r\n"; } For the factory I got: .NET Version: 4.0.30319.239wwReflection Assembly: c:\wwapps\wwhelp\bin\wwreflection20.dllAssembly Cur Dir: c:\wwapps\wwhelpApplicationBase: C:\Programs\vfp9\App Domain: wwReflection534cfa1f For the instance type I got: .NET Version: 4.0.30319.239wwReflection Assembly: C:\\Programs\\vfp9\wwreflection20.dllAssembly Cur Dir: c:\\wwapps\\wwhelpApplicationBase: C:\\Programs\\vfp9\App Domain: wwDotNetBridge_56006605 which clearly shows the problem. You can see that both are loading from different appDomains but the each is loading the assembly from a different location. Probably a better solution yet (for ANY kind of assembly loading problem) is to use the .NET Fusion Log Viewer to trace assembly loads.The Fusion viewer will show a load trace for each assembly loaded and where it's looking to find it. Here's what the viewer looks like: The last trace above that I found for the second wwReflection20 load (the one that is wonky) looks like this:*** Assembly Binder Log Entry (1/13/2012 @ 3:06:49 AM) *** The operation was successful. Bind result: hr = 0x0. The operation completed successfully.

WRN: It is recommended to inspect your application on whether this is intentional or not. WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue. Notice that the fusion log clearly shows that the .NET loader makes no attempt to even load the assembly from the path I explicitly specified. Remember your Assembly Locations As mentioned earlier all failures I've seen like this ultimately resulted from different versions of the same type being available in the two AppDomains. At first sight that seems ridiculous - how could the types be different and why would you have multiple assemblies - but there are actually a number of scenarios where it's quite possible to have multiple copies of the same assembly floating around in multiple places. If you're hosting different environments (like hosting the Razor Engine, or ASP.NET Runtime for example) it's common to create a private BIN folder and it's important to make sure that there's no overlap of assemblies. In my case of Html Help Builder the problem started because I'm using COM interop to access the .NET assembly and the above code. COM Interop has very specific requirements on where assemblies can be found and because I was mucking around with the loader code today, I ended up moving assemblies around to a new location for explicit loading. The explicit load works in the main AppDomain, but failed in the remote domain as I showed. The solution here was simple enough: Delete the extraneous assembly which was left around by accident. Not a common problem, but one that when it bites is pretty nasty to figure out because it seems so unlikely that types wouldn't match. I know I've run into this a few times and writing this down hopefully will make me remember in the future rather than poking around again for an hour trying to debug the issue as I did today. Hopefully it'll save some of you some time as well in the future.© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET  COM   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Addressing a variable in VB

  - by Jeff

  Why doesn't Visual Basic.NET have the addressof operator like C#? In C#, one can int i = 123; int* addr = &i; But VB has no equivalent counter part. It seems like it should be important. UPDATE Since there's some interest, Im copying my response to Strilanc below. The case I ran into didnt necessitate pointers by any means, but I was trying to trouble shoot a unit test that was failing and there was some confusion over whether or not an object being used at one point in the stack was the same object as an object several methods away.

• Day 4 - Game Sprites In Action

  - by dapostolov

  Yesterday I drew an image on the screen. Most exciting, but ... I spent more time blogging about it then actual coding. So this next little while I'm going to streamline my game and research and simply post key notes. Quick notes on the last session: The most important thing I wanted to point out were the following methods:           spriteBatch.Begin(SpriteBlendMode.AlphaBlend);           spriteBatch.Draw(sprite, position, Color.White);           spriteBatch.End(); The spriteBatch object is used to draw Textures and a 2D texture is called a Sprite A texture is generally an image, which is called an Asset in XNA The Draw Method in the Game1.cs is looped (until exit) and utilises the spriteBatch object to draw a Scene To begin drawing a Scene you call the Begin Method. To end a Scene you call the End Method. And to place an image on the Scene you call the Draw method. The most simple implementation of the draw method is:           spriteBatch.Draw(sprite, position, Color.White); 1) sprite - the 2D texture you loaded to draw 2) position - the 2d vector, a set of x & y coordinates 3) Color.White - the tint to apply to the texture, in this case, white light = nothing, nada, no tint. Game Sprites In Action! Today, I played around with Draw methods to get comfortable with their "quirks". The following is an example of the above draw method, but with more parameters available for us to use. Let's investigate!             spriteBatch.Draw(sprite, position2, null, Color.White, MathHelper.ToRadians(45.0f), new Vector2(sprite.Width / 2, sprite.Height / 2), 1.0F, SpriteEffects.None, 0.0F); The parameters (in order): 1) sprite  the texture to display 2) position2 the position on the screen / scene this can also be a rectangle 3) null the portion of the image to display within an image null = display full image this is generally used for animation strips / grids (more on this below) 4) Color.White Texture tinting White = no tint 5) MathHelper.ToRadians(45.0f) rotation of the object, in this case 45 degrees rotates from the set plotting point. 6) new Vector(0,0) the plotting point in this case the top left corner the image will rotate from the top left of the texture in the code above, the point is set to the middle of the image. 7) 1.0f Image scaling (1x) 8) SpriteEffects.None you can flip the image horizontally or vertically 9) 0.0f The z index of the image. 0 = closer, 1 behind? And playing around with different combinations I was able to come up with the following whacky display:   Checking off Yesterdays Intention List: learn game development terminology (in progress) - We learned sprite, scene, texture, and asset. how to place and position (rotate) a static image on the screen (completed) - The thing to note was, it's was in radians and I found a cool helper method to convert degrees into radians. Also, the image rotates from it's specified point. how to layer static images on the screen (completed) - I couldn't seem to get the zIndex working, but one things for sure, the order you draw the image in also determines how it is rendered on the screen. understand image scaling (in progress) - I'm not sure I have this fully covered, but for the most part plug a number in the scaling field and the image grows / shrinks accordingly. can we reuse images? (completed) - yes, I loaded one image and plotted the bugger all over the screen. understand how framerate is handled in XNA (in progress) - I hacked together some code to display the framerate each second. A framerate of 60 appears to be the standard. Interesting to note, the GameTime object does provide you with some cool timing capabilities, such as...is the game running slow? Need to investigate this down the road. how to display text , basic shapes, and colors on the screen (in progress) - i got text rendered on the screen, and i understand containing rectangles. However, I didn't display "shapes" & "colors" how to interact with an image (collision of user input?) (todo) how to animate an image and understand basic animation techniques (in progress) - I was able to create a stripe animation of numbers ranging from 1 - 4, each block was 40 x 40 pixles for a total stripe size of 160 x 40. Using the portion (source Rectangle) parameter, i limited this display to each section at varying intervals. It was interesting to note my first implementation animated at rocket speed. I then tried to create a smoother animation by limiting the redraw capacity, which seemed to work. I guess a little more research will have to be put into this for animating characters / scenes. how to detect colliding images or screen edges (todo) - but the rectangle object can detect collisions I believe. how to manipulate the image, lets say colors, stretching (in progress) - I haven't figured out how to modify a specific color to be another color, but the tinting parameter definately could be used. As for stretching, use the rectangle object as the positioning and the image will stretch to fit! how to focus on a segment of an image...like only displaying a frame on a film reel (completed) - as per basic animation techniques what's the best way to manage images (compression, storage, location, prevent artwork theft, etc.) (todo) Tomorrows Intention Tomorrow I am going to take a stab at rendering a game menu and from there I'm going to investigate how I can improve upon the code and techniques. Intention List: Render a menu, fancy or not Show the mouse cursor Hook up click event A basic animation of somesort Investigate image / menu techniques D.

• Bluetooth Dial-Up Networking using Blueman

  - by leemes

  I want to configure a dial up network connection via bluetooth to my phone in order to access the internet. I use Lubuntu 12.04 (Ubuntu with LXDE) which has the Network Manager Applet and Blueman applet installed. I guess these are the same tools than on an Ubuntu installation, hence I ask my question on this site. My phone is a Sony Ericsson W810i, my laptop is a Lenovo S10-2, my mobile phone provider is o2 Germany. I scanned for my mobile phone using the Blueman applet. I connected the dial-up network via the context menu - Serial Ports - Dial-up Networking. A notification bubble says that the connection is available on the interface named ppp0. ipconfig is telling something different: There is no ppp0 or something similar. I only see my eth0 (wired ethernet), eth1 (wifi) and lo interfaces. Of course, I can't ping google.com as the interface really seems to be not present at all. When the dial-up network is being connected, my mobile phone says that it connects to the internet. Afterwards, I see the active connection on the phone's screen. When successfully connecting with the phone using another computer, it behaves exactly the same, so I guess that the phone isn't the problem. I don't know if I configured the Dial-Up correctly. I use the phone number *99# which is very common on most mobile ISPs. I use the APN which my ISP is telling me to use. (I can't find the number on their support page, so I just use the default value *99#.) My mobile ISP is o2 Germany. There are How-Tos out there which use the Network Manager Applet to setup a bluetooth dial-up connection, but I can't see any bluetooth devices in the context menu as on the screenshots in those How-Tos. Do you have any suggestions what might be wrong / what I should try? EDIT: When choosing "Network Access Point" in the device's context menu instead of Serial Ports - Dial-Up Networking, an interface bnep0 appears. However, neither an IPv4 address is assigned for that interface (but IPv6), nor the phone connects to the internet. Am I missing something? Can I connect to the internet after setting up this network connection?

• What Problems Are Better Solved By SOAP Over REST?

  In the battle for web service supremacy SOAP and REST have been battling for years. In my personal opinion this debate should have never existed. Yes, both forms can be used to create an interactive web service, but each form of a service was developed independent of each other to solve two different yet similar problems. Based my research and experience I would have to say that REST should be the preferred web service methodology and SOAP should only be used in specific situations. Note, I did not say that I was against SOAP, and in fact I actually like to use SOAP when it is needed. Criteria for using SOAP: Does the service need a guaranteed level of reliability and security? Did the provider and consumer of the service agreed on a standardized data exchange format? Does the service need data context and state management? If you answer yes to any of these questions, then you may want to consider SOAP as the format for the web service. Another way to look at the relationship between REST and SOAP is to look at the medical field.  For most things a general doctor or you family health care provider can acceptably treat most conditions from the case of a common cold to a broken bone. A general doctor more aligns with REST in my opinion because for most service requirements REST fulfills a projects needs, but what happens if you need more of an advanced examination, you would go to a specialist. A specialist would already have experience dealing with specific issues that you are experiencing giving them specific context to how best treat you going forward. SOAP acts more like a specialist doctor giving that they understand the context of an issue and can treat it based on the state of other patients they have already treated. An example of where I would use SOAP over REST in real life would be a single sign-on application. I n these cases I need to check validate a username and password for authentication and authorization of a web page request. This service would need to maintain state while it authenticated a user and while it validated access to a web page on a subsequent request. This service must process every request for access and not allow caching to ensure that every request is processed and the appropriate users are allowed to view selected web pages.

• Why All The Hype Around Live Help?

  - by ruth.donohue

  I am pleased to introduce guest blogger, Damien Acheson today. Based in Cambridge, MA, Damien is the Product Marketing Manager for ATG’s Live Help products. Welcome, Damien!! BY DAMIEN ACHESON Why all the hype around live help? An eCommerce professional recently asked me: “Why all the hype around live chat and click to call?” I already have a customer service phone number that’s available to my online visitors. Why would I want to add live help? If anything, I want my website to reduce the number of calls to my contact center, not increase it!” The effect of adding live help to a website is counter-intuitive. Done right, live help doesn’t increase your call volume; it optimizes it by replacing traditional telephone calls with smarter, more productive, live voice and live chat interactions. This generates instant cost savings, and a measurable lift in sales and customer retention. A live help interaction differs from a traditional telephone call in six radical ways: Targeting. With live help you can target specific visitors at just the exact right time with a live call or live chat invitation based on hundreds of different parameters. For example, visitors who appear to hesitate before making a large purchase may receive a live help invitation, while others may not. Productivity. By reserving live voice to visitors with complex questions, and offering self-service and live chat for more simple interactions, agents with the right domain expertise can handle simultaneous queries and achieve substantial productivity gains. Routing. Live help interactions take into account visitors’ web context to intelligently route queries to the best available agent, thereby lifting first contact resolution. Context. Traditional telephone numbers force online customers to “change channels” and “start over” with a phone agent. With Live help, agents get the context of the web session and can instantly access the customer’s transaction details and account information, substantially reducing handle times. Interaction. Agents can solve a customer’s problem more effectively co-browsing and collaborating with the visitor in real-time to complete online forms and transactions. Analytics. Unlike traditional telephone numbers, live help allows you to tie Web analytics to customer satisfaction and agent performance indicators. To better understand these differences and advantages over traditional customer service, watch this demo on optimizing customer interactions with Live Help. Technorati Tags: ATG,Live Help,Commerce

• How does key-based caching work?

  - by Dominic Santos

  I recently read an article on the 37Signals blog and I'm left wondering how it is that they get the cache key. It's all well and good having a cache key that includes the object's timestamp (this means that when you update the object the cache will be invalidated); but how do you then use the cache key in a template without causing a DB hit for the very object that you are trying to fetch from the cache. Specifically, how does this affect One to Many relations where you are rendering a Post's Comments for example. Example in Django: {% for comment in post.comments.all %} {% cache comment.pk comment.modified %} <p>{{ post.body }}</p> {% endcache %} {% endfor %} Is caching in Rails different to just requests to memcached for example (I know that they convert your cache key to something different). Do they also cache the cache key?

• How should I log time spent on multiple tasks?

  - by xenoterracide

  In Joel's blog on evidence based scheduling he suggests making estimates based on the smallest unit of work and logging extra work back to the original task. The problem I'm now experiencing is that I'll have create object A with subtask method A which creates object B and test all of the above. I create tasks for each of these that seems to be resulting in ok-ish estimates (need practice), but when I go to log work I find that I worked on 4 tasks at once because I tweak method A and find a bug in the test and refactor object B all while coding it. How should I go about logging this work? should I say I spent, for example, 2 hours on each of the 4 tasks I worked on in the 8 hour day?

• Mocking HttpContext with JustMock

  - by mehfuzh

  In post , i will show a test code that will mock the various elements needed to complete a HTTP page request and  assert the expected page cycle steps. To begin, i have a simple enumeration that has my predefined page steps: public enum PageStep {     PreInit,     Load,     PreRender,     UnLoad } Once doing so, i  first created the page object [not mocking]. Page page = new Page(); Here, our target is to fire up the page process though ProcessRequest call, now if we take a look inside method though reflector, we will find calls stack like : ProcessRequest –> ProcessRequestWithNoAssert –> SetInstrinsics –> Finallly ProcessRequest. Inside SetIntrinsics , where it requires calls from HttpRequest, HttpResponse and HttpBrowserCababilities. With this , we can easily know what are classes / calls  we need to mock in order to get though the expected call. Accordingly, for  HttpBrowserCapabilities our required test code will look like: Mock.Arrange(() => browser.PreferredRenderingMime).Returns("text/html"); Mock.Arrange(() => browser.PreferredResponseEncoding).Returns("UTF-8"); Mock.Arrange(() => browser.PreferredRequestEncoding).Returns("UTF-8"); Now, HttpBrowserCapabilities is get though [Instance]HttpRequest.Browser. Therefore, we create the HttpRequest mock: var request = Mock.Create<HttpRequest>(); Then , add the required get call : Mock.Arrange(() => request.Browser).Returns(browser); As, [instance]Browser.PerferrredResponseEncoding and [instance]Browser.PreferredResponseEncoding  are also set to the request object and to make that they are set properly, we can add the following lines as well [not required though]. bool requestContentEncodingSet = false; Mock.ArrangeSet(() => request.ContentEncoding = Encoding.GetEncoding("UTF-8")).DoInstead(() =>  requestContentEncodingSet = true); Similarly, for response we can write:  var response = Mock.Create<HttpResponse>();    bool responseContentEncodingSet = false;  Mock.ArrangeSet(() => response.ContentEncoding = Encoding.GetEncoding("UTF-8")).DoInstead(() => responseContentEncodingSet = true); Finally , I created a mock of HttpContext and set the Request and Response properties that will returns the mocked version. var context = Mock.Create<HttpContext>();   Mock.Arrange(() => context.Request).Returns(request); Mock.Arrange(() => context.Response).Returns(response); As, Page internally calls RenderControl method , we just need to replace that with our one and optionally we can check if  invoked properly: bool rendered = false; Mock.Arrange(() => page.RenderControl(Arg.Any<HtmlTextWriter>())).DoInstead(() => rendered = true); That’s  it, the rest of the code is simple,  where  i asserted the page cycle with the PageSteps that i defined earlier: var pageSteps = new Queue<PageStep>();    page.PreInit +=      delegate      {          pageSteps.Enqueue(PageStep.PreInit);      };  page.Load +=      delegate      {          pageSteps.Enqueue(PageStep.Load);      };    page.PreRender +=      delegate      {          pageSteps.Enqueue(PageStep.PreRender);      };    page.Unload +=      delegate      {          pageSteps.Enqueue(PageStep.UnLoad);      };    page.ProcessRequest(context);    Assert.True(requestContentEncodingSet);  Assert.True(responseContentEncodingSet);  Assert.True(rendered);    Assert.Equal(pageSteps.Dequeue(), PageStep.PreInit);  Assert.Equal(pageSteps.Dequeue(), PageStep.Load);  Assert.Equal(pageSteps.Dequeue(), PageStep.PreRender);  Assert.Equal(pageSteps.Dequeue(), PageStep.UnLoad);    Mock.Assert(request);  Mock.Assert(response);   You can get the test class shown in this post here to give a try by yourself with of course JustMock.

• XNA Deferred Shading, Replace BasicEffect

  - by Alex

  I have implemented deferred shading in my XNA 4.0 project, meaning that I need all objects to start out with the same shader "RenderGBuffer.fx". How can I use a custom Content Processor to: Not load any textures by default (I want to manually do this) Use "RenderGBuffer.fx" as the default shader instead of BasicEffect Below is the progress so far public class DeferredModelProcessor : ModelProcessor { EffectMaterialContent deferredShader; public DeferredModelProcessor() { } protected override MaterialContent ConvertMaterial(MaterialContent material, ContentProcessorContext context) { deferredShader = new EffectMaterialContent(); deferredShader.Effect = new ExternalReference<EffectContent>("DeferredShading/RenderGBuffer.fx"); return context.Convert<MaterialContent, MaterialContent>(deferredShader, typeof(MaterialProcessor).Name); } }
