• How to create a virtual network with Azure Connect

  - by Herve Roggero

  If you are trying to establish a virtual network between machines located in disparate networks, you can either use VPN, Virtual Network or Azure Connect. If you want to establish a connection between machines located in Windows Azure, you should consider using the Virtual Network service. If you want to establish a connection between local machines and Virtual Machines in Windows Azure, you may be able to use your existing VPN device (assuming you have one), as long as the device is supported by Microsoft. If the VPN device you are using isn’t supported, or if you are trying to create a virtual network between machines from disparate networks (such as machines located in another cloud provider), you can use Azure Connect. This blog post explains how Azure Connect can help you create virtual networks between multiple servers in the cloud, various servers in different cloud environments, and on-premise. Note: Azure Connect is currently in Technical Preview. About Azure Connect Let’s do a quick review of Azure Connect. This technology implements an IPSec tunnel from machines to to a relay service located in the Microsoft cloud (Azure). So in essence, Azure Connect doesn’t provide a point-to-point connection between machines; the network communication is tunneled through the relay service. The relay service in turn offers a mechanism to enforce basic communication rules that you define through Groups. We will review this later. You could network two or more VMs in the Azure cloud (although you should consider using a Virtual Network if you go this route), or servers in the Azure cloud and other machines in the Amazon cloud for example, or even two or more on-premise servers located in different locations for which a direct network connection is not an option. You can place any number of machines in your topology. Azure Connect gives you great flexibility on how you want to build your virtual network across various environments. So Azure Connect makes sense when you want to: Connect machines located in different cloud providers Connect on-premise machines running in different locations Connect Azure VMs with on-premise (if you do not have a VPN device, or if your device is not supported) Connect Azure Roles (Worker Roles, Web Roles) with on-premise servers or in other cloud providers The diagram below shows you a high level network topology that involves machines in the Windows Azure cloud, other cloud providers and on-premise. You should note that the only required component in this diagram is the Relay itself. The other machines are optional (although your network is useful only if you have two or more machines involved). Relay agents are currently available in three geographic areas: US, Europe and Asia. You can change which region you want to use in the Windows Azure management portal. High Level Network Topology With Azure Connect Azure Connect Agent Azure Connect establishes a virtual network and creates virtual adapters on your machines; these virtual adapters communicate through the Relay using IPSec. This is achieved by installing an agent (the Azure Connect Agent) on all the machines you want in your network topology. However, you do not need to install the agent on Worker Roles and Web Roles; that’s because the agent is already installed for you. Any other machine, including Virtual Machines in Windows Azure, needs the agent installed.  To install the agent, simply go to your Windows Azure portal (http://windows.azure.com) and click on Networks on the bottom left panel. You will see a list of subscriptions under Connect. If you select a subscription, you will be able to click on the Install Local Endpoint icon on top. Clicking on this icon will begin the download and installation process for the agent. Activating Roles for Azure Connect As previously mentioned, you do not need to install the Azure Connect Agent on Worker Roles and Web Roles because it is already loaded. However, you do need to activate them if you want the roles to participate in your network topology. To do this, you will need to click on the Get Activation Token icon. The activation token must then be copied and placed in the configuration file of your roles. For more information on how to perform this step, visit MSDN at http://msdn.microsoft.com/en-us/library/windowsazure/gg432964.aspx. Firewall Rules Note that specific firewall rules must exist to allow the agent to communicate through the Relay. You will need to allow TCP 443 and ICMPv6. For additional information, please visit MSDN at http://msdn.microsoft.com/en-us/library/windowsazure/gg433061.aspx. CA Certificates You can optionally require agents to sign their activation request with the Relay using a trusted certificate issued by a Certificate Authority (CA). Click on Activation Options to learn more. Groups To create your network topology you must first create a group. A group represents a logical container of endpoints (or machines) that can communicate through the Relay. You can create multiple groups allowing you to manage network communication differently. For example you could create a DEVELOPMENT group and a PRODUCTION group. To add an endpoint you must first install an agent that will create a virtual adapter on the machine on which it is installed (as discussed in the previous section). Once you have created a group and installed the agents, the machines will appear in the Windows Azure management portal and you can start assigning machines to groups. The next figure shows you that I created a group called LocalGroup and assigned two machines (both on-premise) to that group. Groups and Computers in Azure Connect As I mentioned previously you can allow these machines to establish a network connection. To do this, you must enable the Interconnected option in the group. The following diagram shows you the definition of the group. In this topology I chose to include local machines only, but I could also add worker roles and web roles in the Azure Roles section (you must first activate your roles, as discussed previously). You could also add other Groups, allowing you to manage inter-group communication. Defining a Group in Azure Connect Testing the Connection Now that my agents have been installed on my two machines, the group defined and the Interconnected option checked, I can test the connection between my machines. The next screenshot shows you that I sent a PING request to DEVLAP02 from DEVDSK02. The PING request was successful. Note however that the time is in the hundreds of milliseconds on average. That is to be expected because the machines are connecting through the Relay located in the cloud. Going through the Relay introduces an extra hop in the communication chain, so if your systems rely on high performance, you may want to conduct some basic performance tests. Sending a PING Request Through The Relay Conclusion As you can see, creating a network topology between machines using the Azure Connect service is simple. It took me less than five minutes to create the above configuration, including the time it took to install the Azure Connect agents on the two machines. The flexibility of Azure Connect allows you to create a virtual network between disparate environments, as long as your operating systems are supported by the agent.

• Learnings from trying to write better software: Loud errors from the very start

  - by theo.spears

  Microsoft made a very small number of backwards incompatible changes between .NET 1.1 and 2.0, because they wanted to make it as easy and safe as possible to port applications to the new runtime. (Here’s a list.) However, one thing they did change was what happens when a background thread fails with an unhanded exception - in .NET 1.1 nothing happened, the thread terminated, and the application continued oblivious. Try the same trick in .NET 2.0 and the entire application, including all threads, will rudely terminate. There are three reasons for this. Firstly if a background thread has crashed, it may have left the entire application in an inconsistent state, in a way that will affect other threads. It’s better to terminate the entire application than continue and have the application perform actions based on a broken state, for example take customer orders, or write corrupt files to disk.  Secondly, during software development, it is far better for errors to be loud and obtrusive. Even if you have unit tests and integration tests (and you should), a key part of ensuring software works properly is to actually try using it, both through systematic testing and through the casual use all software gets by its developers during use. Subtle errors are easy to miss if you are not actually doing real work using the application, loud errors are obvious. Thirdly, and most importantly, even if catching and swallowing exceptions indiscriminately doesn't cause any problems in your application, the presence of unexpected exceptions shows you do not fully understand the behavior of your code. The currently released version of your application may be absolutely correct. However, because your mental model of the behavior is wrong, any future change you make to the program could and probably will introduce critical errors.  This applies to more than just exceptions causing threads to exit, any unexpected state should make the application blow up in an un-ignorable way. The worst thing you can do is silently swallow errors and continue. And let's be clear, writing to a log file does not count as blowing up in an un-ignorable way.  This is all simple as long as the call stack only contains your code, but when your functions start to be called by third party or .NET framework code, it's surprisingly easy for exceptions to start vanishing. Let's look at two examples.   1. Windows forms drag drop events  Usually if you throw an exception from a winforms event handler it will bring up the "application has crashed" dialog with abort and continue options. This is a good default behavior - the error is big and loud, but it is possible for the user to ignore the error and hopefully save their data, if somehow this bug makes it past testing. However drag and drop are different - throw an exception from one of these and it will just be silently swallowed with no explanation.  By the way, it's not just drag and drop events. Timer events do it too.  You can research how exceptions are treated in different handlers and code appropriately, but the safest and most user friendly approach is to always catch exceptions in your event handlers and show your own error message. I'll talk about one good approach to handling these exceptions at the end of this post.   2. SSMS integration for SQL Tab Magic  A while back wrote an SSMS add-in called SQL Tab Magic (learn more about the process here). It works by listening to certain SSMS events and remembering what documents are opened and closed. I deployed it internally and it was used for a few months by a number of people without problems, so I was reasonably confident in its quality. Before releasing I made a few cleanups, including introducing error reporting. Bam. A few days later I was looking at over 1,000 error reports in my inbox. In turns out I wasn't handling table designers properly. The exceptions were there, but again SSMS was helpfully swallowing them all for me, so I was blissfully unaware. Had I made my errors loud from the start, I would have noticed these issues long before and fixed them.   Handling exceptions  Now you are systematically catching exceptions throughout your application, you need to do something with them. I've tried 3 options: log them, alert the user, and automatically send them home.  There are a few good options for logging in .NET. The most widespread is Apache log4net, which provides a very capable and configurable logging framework. There is also NLog which has a compatible interface, with a greater emphasis on fluent rather than XML configuration.  Alerting the user serves two purposes. Firstly it means they understand their action has failed to they don't just assume it worked (Silent file copy failure is a problem if you then delete the originals) or that they should keep waiting for a background task to complete. Secondly, it means the users can report the bug to your support team, and then you can fix it. This means the message you show the user should contain the information you need as a developer to identify and fix it. And the user will probably just send you a screenshot of the dialog, so it shouldn't be hidden by scroll bars.  This leads us to the third option, automatically sending error reports home. By automatic I mean with minimal effort on the part of the user, rather than doing it silently behind their backs. The advantage of this is you can send back far more detailed and precise information than you can expect a user to include in an email, and by making it easier to report errors, you make it more likely users will do so.  We do this using a great tool called SmartAssembly (full disclosure: this is a product made by Red Gate). It captures complete stack traces including the values of all local variables and then allows the user to send all this information back with a single click. We also capture log files to help understand what lead up to the error. We then use the free SmartAssembly Sync for Jira to dedupe these reports and raise them as bugs in our bug tracking system.  The combined effect of loud errors during development and then automatic error reporting once software is deployed allows us to find and fix more bugs, correct misunderstandings on how our software works, and overall is a key piece in delivering higher quality software. However it is no substitute for having motivated cunning testers in the building - and we're looking to hire more of those too.   If you found this post interesting you should follow me on twitter.

• Superclass Sensitive Actions

  - by Geertjan

  I've created a small piece of functionality that enables you to create actions for Java classes in the IDE. When the user right-clicks on a Java class, they will see one or more actions depending on the superclass of the selected class. To explain this visually, here I have "BlaTopComponent.java". I right-click on its node in the Projects window and I see "This is a TopComponent": Indeed, when you look at the source code of "BlaTopComponent.java", you'll see that it implements the TopComponent class. Next, in the screenshot below, you see that I have right-click a different class. In this case, there's an action available because the selected class implements the ActionListener class. Then, take a look at this one. Here both TopComponent and ActionListener are superclasses of the current class, hence both the actions are available to be invoked: Finally, here's a class that subclasses neither TopComponent nor ActionListener, hence neither of the actions that I created for doing something that relates to TopComponents or ActionListeners is available, since those actions are irrelevant in this context: How does this work? Well, it's a combination of my blog entries "Generic Node Popup Registration Solution" and "Showing an Action on a TopComponent Node". The cool part is that the definition of the two actions that you see above is remarkably trivial: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JOptionPane; import org.openide.loaders.DataObject; import org.openide.util.Utilities; public class TopComponentSensitiveAction implements ActionListener { private final DataObject context; public TopComponentSensitiveAction() { context = Utilities.actionsGlobalContext().lookup(DataObject.class); } @Override public void actionPerformed(ActionEvent ev) { //Do something with the context: JOptionPane.showMessageDialog(null, "TopComponent: " + context.getNodeDelegate().getDisplayName()); } } The above is the action that will be available if you right-click a Java class that extends TopComponent. This, in turn, is the action that will be available if you right-click a Java class that implements ActionListener: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JOptionPane; import org.openide.loaders.DataObject; import org.openide.util.Utilities; public class ActionListenerSensitiveAction implements ActionListener { private final DataObject context; public ActionListenerSensitiveAction() { context = Utilities.actionsGlobalContext().lookup(DataObject.class); } @Override public void actionPerformed(ActionEvent ev) { //Do something with the context: JOptionPane.showMessageDialog(null, "ActionListener: " + context.getNodeDelegate().getDisplayName()); } } Indeed, the classes, at this stage are the same. But, depending on what I want to do with TopComponents or ActionListeners, I now have a starting point, which includes access to the DataObject, from where I can get down into the source code, as shown here. This is how the two ActionListeners that you see defined above are registered in the layer, which could ultimately be done via annotations on the ActionListeners, of course: <folder name="Actions"> <folder name="Tools"> <file name="org-netbeans-sbas-impl-TopComponentSensitiveAction.instance"> <attr stringvalue="This is a TopComponent" name="displayName"/> <attr name="instanceCreate" methodvalue="org.netbeans.sbas.SuperclassSensitiveAction.create"/> <attr name="type" stringvalue="org.openide.windows.TopComponent"/> <attr name="delegate" newvalue="org.netbeans.sbas.impl.TopComponentSensitiveAction"/> </file> <file name="org-netbeans-sbas-impl-ActionListenerSensitiveAction.instance"> <attr stringvalue="This is an ActionListener" name="displayName"/> <attr name="instanceCreate" methodvalue="org.netbeans.sbas.SuperclassSensitiveAction.create"/> <attr name="type" stringvalue="java.awt.event.ActionListener"/> <attr name="delegate" newvalue="org.netbeans.sbas.impl.ActionListenerSensitiveAction"/> </file> </folder> </folder> <folder name="Loaders"> <folder name="text"> <folder name="x-java"> <folder name="Actions"> <file name="org-netbeans-sbas-impl-TopComponentSensitiveAction.shadow"> <attr name="originalFile" stringvalue="Actions/Tools/org-netbeans-sbas-impl-TopComponentSensitiveAction.instance"/> <attr intvalue="150" name="position"/> </file> <file name="org-netbeans-sbas-impl-ActionListenerSensitiveAction.shadow"> <attr name="originalFile" stringvalue="Actions/Tools/org-netbeans-sbas-impl-ActionListenerSensitiveAction.instance"/> <attr intvalue="160" name="position"/> </file> </folder> </folder> </folder> </folder> The most important parts of the layer registration are the lines that are highlighted above. Those lines connect the layer to the generic action that delegates back to the action listeners defined above, as follows: public final class SuperclassSensitiveAction extends AbstractAction implements ContextAwareAction { private final Map map; //This method is called from the layer, via "instanceCreate", //magically receiving a map, which contains all the attributes //that are defined in the layer for the file: static SuperclassSensitiveAction create(Map map) { return new SuperclassSensitiveAction(Utilities.actionsGlobalContext(), map); } public SuperclassSensitiveAction(Lookup context, Map m) { super(m.get("displayName").toString()); this.map = m; String superclass = m.get("type").toString(); //Enable the menu item only if //we're dealing with a class of type superclass: JavaSource javaSource = JavaSource.forFileObject( context.lookup(DataObject.class).getPrimaryFile()); try { javaSource.runUserActionTask(new ScanTask(this, superclass), true); } catch (IOException ex) { Exceptions.printStackTrace(ex); } //Hide the menu item if it isn't enabled: putValue(DynamicMenuContent.HIDE_WHEN_DISABLED, true); } @Override public void actionPerformed(ActionEvent ev) { ActionListener delegatedAction = (ActionListener)map.get("delegate"); delegatedAction.actionPerformed(ev); } @Override public Action createContextAwareInstance(Lookup actionContext) { return new SuperclassSensitiveAction(actionContext, map); } private class ScanTask implements Task<CompilationController> { private SuperclassSensitiveAction action = null; private String superclass; private ScanTask(SuperclassSensitiveAction action, String superclass) { this.action = action; this.superclass = superclass; } @Override public void run(final CompilationController info) throws Exception { info.toPhase(Phase.ELEMENTS_RESOLVED); new EnableIfGivenSuperclassMatches(info, action, superclass).scan( info.getCompilationUnit(), null); } } private static class EnableIfGivenSuperclassMatches extends TreePathScanner<Void, Void> { private CompilationInfo info; private final AbstractAction action; private final String superclassName; public EnableIfGivenSuperclassMatches(CompilationInfo info, AbstractAction action, String superclassName) { this.info = info; this.action = action; this.superclassName = superclassName; } @Override public Void visitClass(ClassTree t, Void v) { Element el = info.getTrees().getElement(getCurrentPath()); if (el != null) { TypeElement te = (TypeElement) el; List<? extends TypeMirror> interfaces = te.getInterfaces(); if (te.getSuperclass().toString().equals(superclassName)) { action.setEnabled(true); } else { action.setEnabled(false); } for (TypeMirror typeMirror : interfaces) { if (typeMirror.toString().equals(superclassName)){ action.setEnabled(true); } } } return null; } } } This is a pretty cool solution and, as you can see, very generic. Create a new ActionListener, register it in the layer so that it maps to the generic class above, and make sure to set the type attribute, which defines the superclass to which the action should be sensitive.

• Getting Started With Tailoring Business Processes

  - by Richard Bingham

  In this article, and for the sake of simplicity, we will use the term “On-Premise” to mean a deployment where you have design-time development access to the instance, including administration of the technology components, the applications filesystem, and the database. In reality this might be a local development instance that is then supported by a team who can deploy your customizations to the restricted production instance equivalents. Tools Overview Firstly let’s look at the Design-Time tools within JDeveloper for customizing and extending the artifacts of a Business Process. In essence this falls into two buckets; SOA Composite Editor for working with BPEL processes, and the BPM Studio. The SOA Composite Editor As a standard extension to JDeveloper, this graphical design tool should be familiar to anyone previously worked with Oracle SOA Server. With easy-to-use modeling capability, backed-up by full XML source-view (for read-only), it provides everything that is needed to implement the technical design. In simple terms, once deployed to the remote SOA Server the composite components (like Mediator) leverage the Event Delivery Network (EDN) for interaction with the application logic. If you are customizing an existing Fusion Applications BPEL process then be aware that it does support MDS-based customization layers just like Page Composer where different customizations are used based on the run-time context, like for a specific Product or Business Unit. This also makes them safe from patching and upgrades, although only a single active version of the composite is available at run-time. This is defined by a field on the composite record, available in Enterprise Manager. Obviously if you wish to fire different activities and tasks based on the user context then you can should include switches to fork the flows in your custom BPEL process. Figure 1 – A BPEL process in Composite Editor The following describes the simplified steps for making customizations to BPEL processes. This is the most common method of changing the business processes of Fusion Applications, as over 400 BPEL-based composite applications are provided out-of-the-box. Setup your local Fusion Applications JDeveloper environment. The SOA Composite Editor should be installed as part of the Fusion Applications extension. If there are problems you can also find it under the ‘Check for Updates’ help menu option. Since SOA Server is not part of the JDeveloper integrated WebLogic Server, setup a standalone WebLogic environment for deploying and testing. Obviously you might use a Fusion Applications development instance also. Package the existing standard Fusion Applications SOA Composite using Enterprise Manager and export it as a complete SOA Archive (SAR) file, resulting in a local .jar file. You may need to ask your system administrator for this. Import the exported SAR .jar file into JDeveloper using the File menu, under the option ‘SOA Archive into SOA Project’. In JDeveloper set the appropriate customization layer values, and then change from the default role to the Fusion Applications Customization Developer role. Make the customizations and save the application project. Finally redeploy the composite application, either to a direct Application Server connection, or as a fresh SAR (jar) file that can then be re-imported and deployed via Enterprise Manager. The Business Process Management (BPM) Suite In addition to the relatively low-level development environment associated with BPEL process creation, Oracle provides a suite of products that allow business process adjustments to be made without the need for some of the programming skills.  The aim is to abstract much of the technical implementation and to provide a Business Analyst tools for immediately implementing organization changes. Obviously there are some limitations on what they can do, however the BPM Suite functionality increases with each release and for the majority of the cases the tools remains as applicable as its developer-orientated sister. At the current time business processes must be explicitly coded to support just one of these use-cases, either BPEL for developer use or BPM for business analyst use. That said, they both run on the same SOA Server in much the same way. The components bundled in each SOA Composite Application can be verified by inspection through Enterprise Manager. Figure 2 – A BPM Process in JDeveloper BPM Suite. BPM processes are written in a standard notation (BPMN) and the modeling tools are very similar to that of BPEL. The steps to deploy a custom BPM process are also essentially much the same, since the BPM process is bundled into a SOA Composite just like a BPEL process. As such the SOA Composite Editor  actually has support for both artifacts and even allows use of them together, such as a calling a BPM process as a partnerlink from a BPEL process. For more details see the references below. Business Analyst Tooling In addition to using JDeveloper extensions for BPM development, there are run-time tools that Business Analysts can use to make adjustments, so that without high costs of an IT project the system can be tuned to match changes to the business operation. The first tool to consider is the BPM Composer, deployed with the middleware SOA Server and accessible online, and for Fusion Applications it is under the Business Process icon on the homepage of the Application Composer. Figure 3 – Business Process Composer showing a CRM process flow. The key difference between this and using JDeveloper is that the BPM Composer has a Business Catalog prepopulated with features and functions that can be used, mostly through registered WebServices. This means no coding or complex interface development is required, simply drag-drop-configure. The items in the business catalog are seeded by either Oracle (as a BPM Template) or added to by your own custom development. You cannot create or generate catalog content from BPM Composer directly. As per the screenshot you can see the Business Catalog content in the BPM Project browser region. In addition, other online tools for use by Business Analysts include the BPM Worklist application for editing business rules and approval management configuration, plus the SOA Composer which focuses on non-approval business rules and domain value maps. At the current time there are only a handful of BPM processes shipped with Fusion Applications HCM and CRM, including on-boarding workers and processing customer registrations.  This also means a limited number of associated BPM Templates provided out-of-the-box, therefore a limited Business Catalog. That said, BPM-based extension is a powerful capability to leverage and will most likely develop going forwards, especially for use in SaaS deployments where full design-time JDeveloper access is not available.

• how to define a field of view for the entire map for shadow?

  - by Mehdi Bugnard

  I recently added "Shadow Mapping" in my XNA games to include shadows. I followed the nice and famous tutorial from "Riemers" : http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series3/Shadow_map.php . This code work nice and I can see my source of light and shadow. But the problem is that my light source does not match the field of view that I created. I want the light covers the entire map of my game. I don't know why , but the light only affect 2-3 cubes of my map. ScreenShot: (the emission of light illuminates only 2-3 blocks and not the full map) Here is my code i create the fieldOfView for LightviewProjection Matrix: Vector3 lightDir = new Vector3(10, 52, 10); lightPos = new Vector3(10, 52, 10); Matrix lightsView = Matrix.CreateLookAt(lightPos, new Vector3(105, 50, 105), new Vector3(0, 1, 0)); Matrix lightsProjection = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver2, 1f, 20f, 1000f); lightsViewProjectionMatrix = lightsView * lightsProjection; As you can see , my nearPlane and FarPlane are set to 20f and 100f . So i don't know why the light stop after 2 cubes. it's should be bigger Here is set the value to my custom effect HLSL in the shader file /* SHADOW VALUE */ effectWorld.Parameters["LightDirection"].SetValue(lightDir); effectWorld.Parameters["xLightsWorldViewProjection"].SetValue(Matrix.Identity * .lightsViewProjectionMatrix); effectWorld.Parameters["xWorldViewProjection"].SetValue(Matrix.Identity * arcadia.camera.View * arcadia.camera.Projection); effectWorld.Parameters["xLightPower"].SetValue(1f); effectWorld.Parameters["xAmbient"].SetValue(0.3f); Here is my custom HLSL shader effect file "*.fx" // This sample uses a simple Lambert lighting model. float3 LightDirection = normalize(float3(-1, -1, -1)); float3 DiffuseLight = 1.25; float3 AmbientLight = 0.25; uniform const float3 DiffuseColor = 1; uniform const float Alpha = 1; uniform const float3 EmissiveColor = 0; uniform const float3 SpecularColor = 1; uniform const float SpecularPower = 16; uniform const float3 EyePosition; // FOG attribut uniform const float FogEnabled ; uniform const float FogStart ; uniform const float FogEnd ; uniform const float3 FogColor ; float3 cameraPos : CAMERAPOS; texture Texture; sampler Sampler = sampler_state { Texture = (Texture); magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = mirror; AddressV = mirror; }; texture xShadowMap; sampler ShadowMapSampler = sampler_state { Texture = <xShadowMap>; magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = clamp; AddressV = clamp; }; /* *************** */ /* SHADOW MAP CODE */ /* *************** */ struct SMapVertexToPixel { float4 Position : POSITION; float4 Position2D : TEXCOORD0; }; struct SMapPixelToFrame { float4 Color : COLOR0; }; struct SSceneVertexToPixel { float4 Position : POSITION; float4 Pos2DAsSeenByLight : TEXCOORD0; float2 TexCoords : TEXCOORD1; float3 Normal : TEXCOORD2; float4 Position3D : TEXCOORD3; }; struct SScenePixelToFrame { float4 Color : COLOR0; }; float DotProduct(float3 lightPos, float3 pos3D, float3 normal) { float3 lightDir = normalize(pos3D - lightPos); return dot(-lightDir, normal); } SSceneVertexToPixel ShadowedSceneVertexShader(float4 inPos : POSITION, float2 inTexCoords : TEXCOORD0, float3 inNormal : NORMAL) { SSceneVertexToPixel Output = (SSceneVertexToPixel)0; Output.Position = mul(inPos, xWorldViewProjection); Output.Pos2DAsSeenByLight = mul(inPos, xLightsWorldViewProjection); Output.Normal = normalize(mul(inNormal, (float3x3)World)); Output.Position3D = mul(inPos, World); Output.TexCoords = inTexCoords; return Output; } SScenePixelToFrame ShadowedScenePixelShader(SSceneVertexToPixel PSIn) { SScenePixelToFrame Output = (SScenePixelToFrame)0; float2 ProjectedTexCoords; ProjectedTexCoords[0] = PSIn.Pos2DAsSeenByLight.x / PSIn.Pos2DAsSeenByLight.w / 2.0f + 0.5f; ProjectedTexCoords[1] = -PSIn.Pos2DAsSeenByLight.y / PSIn.Pos2DAsSeenByLight.w / 2.0f + 0.5f; float diffuseLightingFactor = 0; if ((saturate(ProjectedTexCoords).x == ProjectedTexCoords.x) && (saturate(ProjectedTexCoords).y == ProjectedTexCoords.y)) { float depthStoredInShadowMap = tex2D(ShadowMapSampler, ProjectedTexCoords).r; float realDistance = PSIn.Pos2DAsSeenByLight.z / PSIn.Pos2DAsSeenByLight.w; if ((realDistance - 1.0f / 100.0f) <= depthStoredInShadowMap) { diffuseLightingFactor = DotProduct(xLightPos, PSIn.Position3D, PSIn.Normal); diffuseLightingFactor = saturate(diffuseLightingFactor); diffuseLightingFactor *= xLightPower; } } float4 baseColor = tex2D(Sampler, PSIn.TexCoords); Output.Color = baseColor*(diffuseLightingFactor + xAmbient); return Output; } SMapVertexToPixel ShadowMapVertexShader(float4 inPos : POSITION) { SMapVertexToPixel Output = (SMapVertexToPixel)0; Output.Position = mul(inPos, xLightsWorldViewProjection); Output.Position2D = Output.Position; return Output; } SMapPixelToFrame ShadowMapPixelShader(SMapVertexToPixel PSIn) { SMapPixelToFrame Output = (SMapPixelToFrame)0; Output.Color = PSIn.Position2D.z / PSIn.Position2D.w; return Output; } /* ******************* */ /* END SHADOW MAP CODE */ /* ******************* */ / For rendering without instancing. technique ShadowMap { pass Pass0 { VertexShader = compile vs_2_0 ShadowMapVertexShader(); PixelShader = compile ps_2_0 ShadowMapPixelShader(); } } technique ShadowedScene { /* pass Pass0 { VertexShader = compile vs_2_0 VSBasicTx(); PixelShader = compile ps_2_0 PSBasicTx(); } */ pass Pass1 { VertexShader = compile vs_2_0 ShadowedSceneVertexShader(); PixelShader = compile ps_2_0 ShadowedScenePixelShader(); } } technique SimpleFog { pass Pass0 { VertexShader = compile vs_2_0 VSBasicTx(); PixelShader = compile ps_2_0 PSBasicTx(); } } I edited my fx file , for show you only information and functions about the shadow ;-)

• UV Atlas Generation and Seam Removal

  - by P. Avery

  I'm generating light maps for scene mesh objects using DirectX's UV Atlas Tool( D3DXUVAtlasCreate() ). I've succeeded in generating an atlas, however, when I try to render the mesh object using the atlas the seams are visible on the mesh. Below are images of a lightmap generated for a cube. Here is the code I use to generate a uv atlas for a cube: struct sVertexPosNormTex { D3DXVECTOR3 vPos, vNorm; D3DXVECTOR2 vUV; sVertexPosNormTex(){} sVertexPosNormTex( D3DXVECTOR3 v, D3DXVECTOR3 n, D3DXVECTOR2 uv ) { vPos = v; vNorm = n; vUV = uv; } ~sVertexPosNormTex() { } }; // create a light map texture to fill programatically hr = D3DXCreateTexture( pd3dDevice, 128, 128, 1, 0, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, &pLightmap ); if( FAILED( hr ) ) { DebugStringDX( "Main", "Failed to D3DXCreateTexture( lightmap )", __LINE__, hr ); return hr; } // get the zero level surface from the texture IDirect3DSurface9 *pS = NULL; pLightmap->GetSurfaceLevel( 0, &pS ); // clear surface pd3dDevice->ColorFill( pS, NULL, D3DCOLOR_XRGB( 0, 0, 0 ) ); // load a sample mesh DWORD dwcMaterials = 0; LPD3DXBUFFER pMaterialBuffer = NULL; V_RETURN( D3DXLoadMeshFromX( L"cube3.x", D3DXMESH_MANAGED, pd3dDevice, &pAdjacency, &pMaterialBuffer, NULL, &dwcMaterials, &g_pMesh ) ); // generate adjacency DWORD *pdwAdjacency = new DWORD[ 3 * g_pMesh->GetNumFaces() ]; g_pMesh->GenerateAdjacency( 1e-6f, pdwAdjacency ); // create light map coordinates LPD3DXMESH pMesh = NULL; LPD3DXBUFFER pFacePartitioning = NULL, pVertexRemapArray = NULL; FLOAT resultStretch = 0; UINT numCharts = 0; hr = D3DXUVAtlasCreate( g_pMesh, 0, 0, 128, 128, 3.5f, 0, pdwAdjacency, NULL, NULL, NULL, NULL, NULL, 0, &pMesh, &pFacePartitioning, &pVertexRemapArray, &resultStretch, &numCharts ); if( SUCCEEDED( hr ) ) { // release and set mesh SAFE_RELEASE( g_pMesh ); g_pMesh = pMesh; // write mesh to file hr = D3DXSaveMeshToX( L"cube4.x", g_pMesh, 0, ( const D3DXMATERIAL* )pMaterialBuffer->GetBufferPointer(), NULL, dwcMaterials, D3DXF_FILEFORMAT_TEXT ); if( FAILED( hr ) ) { DebugStringDX( "Main", "Failed to D3DXSaveMeshToX() at OnD3D9CreateDevice()", __LINE__, hr ); } // fill the the light map hr = BuildLightmap( pS, g_pMesh ); if( FAILED( hr ) ) { DebugStringDX( "Main", "Failed to BuildLightmap()", __LINE__, hr );

SAFE_RELEASE( pMaterialBuffer ); Here is code to fill lightmap texture: HRESULT BuildLightmap( IDirect3DSurface9 *pS, LPD3DXMESH pMesh ) { HRESULT hr = S_OK; // validate lightmap texture surface and mesh if( !pS || !pMesh ) return E_POINTER; // lock the mesh vertex buffer sVertexPosNormTex *pV = NULL; pMesh->LockVertexBuffer( D3DLOCK_READONLY, ( void** )&pV ); // lock the mesh index buffer WORD *pI = NULL; pMesh->LockIndexBuffer( D3DLOCK_READONLY, ( void** )&pI ); // get the lightmap texture surface description D3DSURFACE_DESC desc; pS->GetDesc( &desc ); // lock the surface rect to fill with color data D3DLOCKED_RECT rct; hr = pS->LockRect( &rct, NULL, 0 ); if( FAILED( hr ) ) { DebugStringDX( "main.cpp:", "Failed to IDirect3DTexture9::LockRect()", __LINE__, hr ); return hr; } // iterate the pixels of the lightmap texture // check each pixel to see if it lies between the uv coordinates of a cube face BYTE *pBuffer = ( BYTE* )rct.pBits; for( UINT y = 0; y < desc.Height; ++y ) { BYTE* pBufferRow = ( BYTE* )pBuffer; for( UINT x = 0; x < desc.Width * 4; x+=4 ) { // determine the pixel's uv coordinate D3DXVECTOR2 p( ( ( float )x / 4.0f ) / ( float )desc.Width + 0.5f / 128.0f, y / ( float )desc.Height + 0.5f / 128.0f ); // for each face of the mesh // check to see if the pixel lies within the face's uv coordinates for( UINT i = 0; i < 3 * pMesh->GetNumFaces(); i +=3 ) { sVertexPosNormTex v[ 3 ]; v[ 0 ] = pV[ pI[ i + 0 ] ]; v[ 1 ] = pV[ pI[ i + 1 ] ]; v[ 2 ] = pV[ pI[ i + 2 ] ]; if( TexcoordIsWithinBounds( v[ 0 ].vUV, v[ 1 ].vUV, v[ 2 ].vUV, p ) ) { // the pixel lies b/t the uv coordinates of a cube face // light contribution functions aren't needed yet //D3DXVECTOR3 vPos = TexcoordToPos( v[ 0 ].vPos, v[ 1 ].vPos, v[ 2 ].vPos, v[ 0 ].vUV, v[ 1 ].vUV, v[ 2 ].vUV, p ); //D3DXVECTOR3 vNormal = v[ 0 ].vNorm; // set the color of this pixel red( for demo ) BYTE ba[] = { 0, 0, 255, 255, }; //ComputeContribution( vPos, vNormal, g_sLight, ba ); // copy the byte array into the light map texture memcpy( ( void* )&pBufferRow[ x ], ( void* )ba, 4 * sizeof( BYTE ) ); } } } // go to next line of the texture pBuffer += rct.Pitch; } // unlock the surface rect pS->UnlockRect(); // unlock mesh vertex and index buffers pMesh->UnlockIndexBuffer(); pMesh->UnlockVertexBuffer(); // write the surface to file hr = D3DXSaveSurfaceToFile( L"LightMap.jpg", D3DXIFF_JPG, pS, NULL, NULL ); if( FAILED( hr ) ) DebugStringDX( "Main.cpp", "Failed to D3DXSaveSurfaceToFile()", __LINE__, hr ); return hr; } bool TexcoordIsWithinBounds( const D3DXVECTOR2 &t0, const D3DXVECTOR2 &t1, const D3DXVECTOR2 &t2, const D3DXVECTOR2 &p ) { // compute vectors D3DXVECTOR2 v0 = t1 - t0, v1 = t2 - t0, v2 = p - t0; float f00 = D3DXVec2Dot( &v0, &v0 ); float f01 = D3DXVec2Dot( &v0, &v1 ); float f02 = D3DXVec2Dot( &v0, &v2 ); float f11 = D3DXVec2Dot( &v1, &v1 ); float f12 = D3DXVec2Dot( &v1, &v2 ); // Compute barycentric coordinates float invDenom = 1 / ( f00 * f11 - f01 * f01 ); float fU = ( f11 * f02 - f01 * f12 ) * invDenom; float fV = ( f00 * f12 - f01 * f02 ) * invDenom; // Check if point is in triangle if( ( fU >= 0 ) && ( fV >= 0 ) && ( fU + fV < 1 ) ) return true; return false; } Screenshot Lightmap I believe the problem comes from the difference between the lightmap uv coordinates and the pixel center coordinates...for example, here are the lightmap uv coordinates( generated by D3DXUVAtlasCreate() ) for a specific face( tri ) within the mesh, keep in mind that I'm using the mesh uv coordinates to write the pixels for the texture: v[ 0 ].uv = D3DXVECTOR2( 0.003581, 0.295631 ); v[ 1 ].uv = D3DXVECTOR2( 0.003581, 0.003581 ); v[ 2 ].uv = D3DXVECTOR2( 0.295631, 0.003581 ); the lightmap texture size is 128 x 128 pixels. The upper-left pixel center coordinates are: float halfPixel = 0.5 / 128 = 0.00390625; D3DXVECTOR2 pixelCenter = D3DXVECTOR2( halfPixel, halfPixel ); will the mapping and sampling of the lightmap texture will require that an offset be taken into account or that the uv coordinates are snapped to the pixel centers..? ...Any ideas on the best way to approach this situation would be appreciated...What are the common practices?

• Chrome and Firefox not able to find some sites after Ubuntu's recent update?

  - by gkr

  Loading of revision3.com in Chrome stops and status saying "waiting for static.inplay.tubemogul.com" grooveshark.com in Chrome never loads But wikipedia.org, google.com works just normal same behavior in Firefox too. I use wired DSL connection in Ubuntu 12.04. I guess this started happening after I upgraded the Chrome browser or Flash plugin few days ago from Ubuntu updates through update-manager.

• Ubuntu 12.04 wireless (wifi) not working, can not upgrade to 12.10, touchpad gestures not working. What to do?

  I installed ubuntu 12.04 LTS 3 days ago and since then wireless feature and touchpad gestures are not working. Tried everything on internet but still unsuccessful. I cant upgrade to ubuntu 12.10.

• Notes on implementing Visual Studio 2010 Navigate To

  - by cyberycon

  One of the many neat functions added to Visual Studio in VS 2010 was the Navigate To feature. You can find it by clicking Edit, Navigate To, or by using the keyboard shortcut Ctrl, (yes, that's control plus the comma key). This pops up the Navigate To dialog that looks like this: As you type, Navigate To starts searching through a number of different search providers for your term. The entries in the list change as you type, with most providers doing some kind of fuzzy or at least substring matching. If you have C#, C++ or Visual Basic projects in your solution, all symbols defined in those projects are searched. There's also a file search provider, which displays all matching filenames from projects in the current solution as well. And, if you have a Visual Studio package of your own, you can implement a provider too. Micro Focus (where I work) provide the Visual COBOL language inside Visual Studio (http://visualstudiogallery.msdn.microsoft.com/ef9bc810-c133-4581-9429-b01420a9ea40 ), and we wanted to provide this functionality too. This post provides some notes on the things I discovered mainly through trial and error, but also with some kind help from devs inside Microsoft. The expectation of Navigate To is that it searches across the whole solution, not just the current project. So in our case, we wanted to search for all COBOL symbols inside all of our Visual COBOL projects inside the solution. So first of all, here's the Microsoft documentation on Navigate To: http://msdn.microsoft.com/en-us/library/ee844862.aspx . It's the reference information on the Microsoft.VisualStudio.Language.NavigateTo.Interfaces Namespace, and it lists all the interfaces you will need to implement to create your own Navigate To provider. Navigate To uses Visual Studio's latest mechanism for integrating external functionality and services, Managed Extensibility Framework (MEF). MEF components don't require any registration with COM or any other registry entries to be found by Visual Studio. Visual Studio looks in several well-known locations for manifest files (extension.vsixmanifest). It then uses reflection to scan for MEF attributes on classes in the assembly to determine which functionality the assembly provides. MEF itself is actually part of the .NET framework, and you can learn more about it here: http://mef.codeplex.com/. To get started with Visual Studio and MEF you could do worse than look at some of the editor examples on the VSX page http://archive.msdn.microsoft.com/vsx . I've also written a small application to help with switching between development and production MEF assemblies, which you can find on Codeproject: http://www.codeproject.com/KB/miscctrl/MEF_Switch.aspx. The Navigate To interfaces Back to Navigate To, and summarizing the MSDN reference documentation, you need to implement the following interfaces: INavigateToItemProviderFactoryThis is Visual Studio's entry point to your Navigate To implementation, and you must decorate your implementation with the following MEF export attribute: [Export(typeof(INavigateToItemProviderFactory))]  INavigateToItemProvider Your INavigateToItemProviderFactory needs to return your implementation of INavigateToItemProvider. This class implements StartSearch() and StopSearch(). StartSearch() is the guts of your provider, and we'll come back to it in a minute. This object also needs to implement IDisposeable(). INavigateToItemDisplayFactory Your INavigateToItemProvider hands back NavigateToItems to the NavigateTo framework. But to give you good control over what appears in the NavigateTo dialog box, these items will be handed back to your INavigateToItemDisplayFactory, which must create objects implementing INavigateToItemDisplay  INavigateToItemDisplay Each of these objects represents one result in the Navigate To dialog box. As well as providing the description and name of the item, this object also has a NavigateTo() method that should be capable of displaying the item in an editor when invoked. Carrying out the search The lifecycle of your INavigateToItemProvider is the same as that of the Navigate To dialog. This dialog is modal, which makes your implementation a little easier because you know that the user can't be changing things in editors and the IDE while this dialog is up. But the Navigate To dialog DOES NOT run on the main UI thread of the IDE – so you need to be aware of that if you want to interact with editors or other parts of the IDE UI. When the user invokes the Navigate To dialog, your INavigateToItemProvider gets sent a TryCreateNavigateToItemProvider() message. Instantiate your INavigateToItemProvider and hand this back. The sequence diagram below shows what happens next. Your INavigateToItemProvider will get called with StartSearch(), and passed an INavigateToCallback. StartSearch() is an asynchronous request – you must return from this method as soon as possible, and conduct your search on a separate thread. For each match to the search term, instantiate a NavigateToItem object and send it to INavigateToCallback.AddItem(). But as the user types in the Search Terms field, NavigateTo will invoke your StartSearch() method repeatedly with the changing search term. When you receive the next StartSearch() message, you have to abandon your current search, and start a new one. You can't rely on receiving a StopSearch() message every time. Finally, when the Navigate To dialog box is closed by the user, you will get a Dispose() message – that's your cue to abandon any uncompleted searches, and dispose any resources you might be using as part of your search. While you conduct your search invoke INavigateToCallback.ReportProgress() occasionally to provide feedback about how close you are to completing the search. There does not appear to be any particular requirement to how often you invoke ReportProgress(), and you report your progress as the ratio of two integers. In my implementation I report progress in terms of the number of symbols I've searched over the total number of symbols in my dictionary, and send a progress report every 16 symbols. Displaying the Results The Navigate to framework invokes INavigateToItemDisplayProvider.CreateItemDisplay() once for each result you passed to the INavigateToCallback. CreateItemDisplay() is passed the NavigateToItem you handed to the callback, and must return an INavigateToItemDisplay object. NavigateToItem is a sealed class which has a few properties, including the name of the symbol. It also has a Tag property, of type object. This enables you to stash away all the information you will need to create your INavigateToItemDisplay, which must implement an INavigateTo() method to display a symbol in an editor IDE when the user double-clicks an entry in the Navigate To dialog box. Since the tag is of type object, it is up to you, the implementor, to decide what kind of object you store in here, and how it enables the retrieval of other information which is not included in the NavigateToItem properties. Some of the INavigateToItemDisplay properties are self-explanatory, but a couple of them are less obvious: Additional informationThe string you return here is displayed inside brackets on the same line as the Name property. In English locales, Visual Studio includes the preposition "of". If you look at the first line in the Navigate To screenshot at the top of this article, Book_WebRole.Default is the additional information for textBookAuthor, and is the namespace qualified type name the symbol appears in. For procedural COBOL code we display the Program Id as the additional information DescriptionItemsYou can use this property to return any textual description you want about the item currently selected. You return a collection of DescriptionItem objects, each of which has a category and description collection of DescriptionRun objects. A DescriptionRun enables you to specify some text, and optional formatting, so you have some control over the appearance of the displayed text. The DescriptionItems property is displayed at the bottom of the Navigate To dialog box, with the Categories on the left and the Descriptions on the right. The Visual COBOL implementation uses it to display more information about the location of an item, making it easier for the user to know disambiguate duplicate names (something there can be a lot of in large COBOL applications). Summary I hope this article is useful for anyone implementing Navigate To. It is a fantastic navigation feature that Microsoft have added to Visual Studio, but at the moment there still don't seem to be any examples on how to implement it, and the reference information on MSDN is a little brief for anyone attempting an implementation.

• Sending notification after an event has remained open for a specified period

  - by Loc Nhan

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Enterprise Manager (EM) 12c allows you to create an incident rule to send a notification and/or create an incident after an event has been open for a specified period. Such an incident rule will help prevent premature alerts on issues that may correct themselves within a certain amount of time. For example, there are some agents in an unstable network area, and often there are communication failures between the agents and the OMS lasting three, four minutes at a time. In this scenario, you may only want to receive alerts after an agent in that area has been in the Agent Unreachable status for at least five minutes. Note: Many non-target availability metrics allow users to specify the “number of occurrences” or the number of consecutive times metric values reach thresholds before a notification is sent. It is best to use the feature for such metrics. This article provides a step-by-step guide for creating an incident rule set to cater for the above scenario, that is, to create an incident and send a notification after the Agent Unreachable event has remained open for a five-minute duration. Steps to create the incident rule 1.     Log on to the console and navigate to Setup -> Incidents -> Incident Rules. Note: A non-super user requires the Create Enterprise Rule Set privilege, which is a resource privilege, to create an incident rule. The Incident Rules - All Enterprise Rules page displays. 2.     Click Create Rule Set … The Create Rule Set page displays. 3.     Enter a name for the rule set (e.g. Rule set for agents in flaky network areas), optionally enter a description, and leave everything else at default values, and click + Add. The Search and Select: Targets page pops up. Note:  While you can create a rule set for individual targets, it is a best practice to use a group for this purpose. 4.     Select an appropriate group, e.g. the AgentsInFlakyNework group. The Select button becomes enabled, click the button. The Create Rule Set page displays. 5.     Leave everything at default values, and click the Rules tab. The Create Rule Set page displays. 6.     Click Create… The Select Type of Rule to Create page pops up. 7.     Leave the Incoming events and updates to events option selected, and click Continue. The Create New Rule : Select Events page displays. 8.     Select Target Availability from the Type drop-down list. The page shows more options for Target Availability. 9.     Select the Specific events of type Target Availability option, and click + Add. The Select Target Availability events page pops up. 10.   Select Agent from the Target Type dropdown list. The page expands. 11.   Click the Agent unreachable checkbox, and click OK. Note: If you want to also receive a notification when the event is cleared, click the Agent unreachable end checkbox as well before clicking OK. The Create New Rule : Select Events page displays. 12.   Click Next. The Create New Rule : Add Actions page displays. 13.   Click + Add. The Add Actions page displays. 14.   Do the following: a.     Select the Only execute the actions if specified conditions match option (You don’t want the action to trigger always). The following options appear in the Conditions for Actions section. b.     Select the Event has been open for specified duration option. The Conditions for actions section expands. c.     Change the values of Event has been open for to 5 Minutes as shown below. d.     In the Create Incident or Update Incident section, click the Create Incident checkbox as following: e.     In the Notifications section, enter an appropriate EM user or email address in the E-mail To field. f.     Click Continue (in the top right hand corner). The Create New Rule : Add Actions page displays. 15.   Click Next. The Create New Rule : Specify name and Description page displays. 16.   Enter a rule name, and click Next. The Create New Rule : Review page appears. 17.   Click Continue, and proceed to save the rule set. The incident rule set creation completes. After one of the agents in the group specified in the rule set is stopped for over 5 minutes, EM will send a mail notification and create an incident as shown in the following screenshot. In conclusion, you have seen the steps to create an example incident rule set that only creates an incident and triggers a notification after an event has been open for a specified period. Such an incident rule can help prevent unnecessary incidents and alert notifications leaving EM administrators time to more important tasks. - Loc Nhan

• How to use BCDEdit to dual boot Windows installations?

  - by Ian Boyd

  What are the bcdedit commands necessary to setup dual boot between different installations of Windows?5 Background i recently installed Windows 8 onto a separate hard drive1. Now that Windows 8 in installed i want to dual-boot back to Windows 7. i have my two2 hard drives: So you can see that i have my two disks, with the partitions containing Windows: Windows 7: \\PhysicalDisk0 (partition 03) Windows 8: \\PhysicalDisk2 (partition 1) What i'm trying to figure out how is how to use bcdedit to instruct the thing that boots Windows that there is another Windows installation out there. Running bcdedit now, it shows current configuration: C:\WINDOWS\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=\Device\HarddiskVolume2 description Windows Boot Manager locale en-US inherit {globalsettings} integrityservices Enable default {current} resumeobject {ce153eb7-3786-11e2-87c0-e740e123299f} displayorder {current} toolsdisplayorder {memdiag} timeout 30 Windows Boot Loader ------------------- identifier {current} device partition=C: path \WINDOWS\system32\winload.exe description Windows 8 locale en-US inherit {bootloadersettings} recoverysequence {ce153eb9-3786-11e2-87c0-e740e123299f} integrityservices Enable recoveryenabled Yes allowedinmemorysettings 0x15000075 osdevice partition=C: systemroot \WINDOWS resumeobject {ce153eb7-3786-11e2-87c0-e740e123299f} nx OptIn bootmenupolicy Standard hypervisorlaunchtype Auto i cannot find any documentation on the difference between Windows Boot Manager and Windows Boot Loader. Documentation There is some documentation on Bcdedit: Technet: Command Line Reference - Bcdedit Technet: Windows Automated Installation Kit - BCDEdit Command Line Options Whitepaper - BCDEdit Commands for Boot Environment (Word Document) But they don't explain how edit the binary boot configuration data If i had to guess, i would think that a Windows Boot Manager instructs the BIOS what program it should run. That program would give the user a set of boot choices. That leaves Windows Boot Loader do be a particular boot choice, that represents a particular installation of Windows. If that is the case i would need to create a new Windows Boot Loader entry. This means i might want to use the /create parameter: /create Creates a new boot entry: bcdedit [/store filename] /create [id] /d description [/application apptype | /inherit [apptype] | /inherit DEVICE | /device] So i assume a syntax of: >bcdedit /create /d "The old Windows 7" /application osloader Where application can be one of the following types: Apptype Description BOOTSECTOR The boot sector application OSLOADER The Windows boot loader RESUME A resume application Unfortunately, the only documentation about osloader is "The Windows boot loader". i don't see how that can differentiate between Windows 8 on one hard drive, and Windows 7 on another. The other possible parameter when /create a boot loader is >bcdedit /create /D "Windows Vista" /device "The Quick Brown Fox" Unfortunately the documentation is missing for /device: /device Optional. If id is not set to a well-known identifier, the option that is used to specify the new boot entry as an additional device options entry. Since i did not set id to a well-known identifier, i must set /device to "the option that is used to specify the new boot entry as an additional device options entry". i know all those words; they're all English. But i have on idea what it is saying; those words in that order seem nonsensical. So i'm somewhat stymied. i don't want to be like Dan Stolts from Microsoft: I found no content that was particularly helpful when I hosed my machine by playing with BCDEdit. This post would have been ok if there was much more detail especially on the /set command OSDevice, etc. So once I got my machine fixed, I documented the solution and the information is here.... i mean, if a Microsoft guy can't even figure out how to use BCDEdit to edit his BCD, then what chance to i have? Bonus Reading BCDEdit Command-Line Options Bcdedit Server 2008 R2 or Windows 7 System Will NOT Boot After Making Changes To Boot Manager Using BCDEdit Visual BCD Editor4 Windows 7 and Windows 8 RTM Dual Boot Setup Footnotes 1 Since the Windows 8 installer would have damaged my Windows 7 install, i decided to unplug my "main" hard drive during the install. Which is a long-winded explanation of why the Windows 8 installer didn't detect the existing Windows 7 install. Normally the installer would have automatically created the required entries for dual-boot. Not that the reason i'm asking the question is important. 2 Really there's three drives, but the third is just bulk storage. The existence of a 3rd hard drive is irrelevant to the question. i only mention it in case someone wants to know why the screenshot has 3 hard drives when i only mention two. 3 i arbitrarily started numbering partitions at "zero"; not to imply that partitions are numbered starting at zero. i only mention partitions because i don't see how any boot-loader could do its job without knowing which partition, and which folder, an installation of Windows is located in. 4 i'm asking about BCDEdit. i tried Visual BCD Editor. It seems to be a visual BCD editor. That is to say that it's a GUI, but still uses the same terminology as BCDEdit, and requires the same knowledge that BCD doesn't document. 5 For simplicity sake we'll assume that all installation of Windows i want to dual-boot between are Windows Vista or later, making them all compatible with the BCDEdit and the binary boot loader. The alternative would require delving into the intricacies of the old ntloader. Nor am i asking about dual booting to Linux; or how to boot to a Virtual Hard Drive (vhd) image. Just modern versions of Windows on existing hard drives in the same machine. Note: You can ignore everything after the word Background. It's all pointless exposition to satisfy some people's need for "research effort" before they'll consider being helpful. Some people have even been known to summarily close questions unless there is research effort. Some people have been know to close questions if there is too much research effort. Some people close questions when i put the note saying that they can ignore everything after the Background out of spite. Some people are just grumpy.

• Setting up a VPN connection to Amazon VPC - routing

  - by Keeno

  I am having some real issues setting up a VPN between out office and AWS VPC. The "tunnels" appear to be up, however I don't know if they are configured correctly. The device I am using is a Netgear VPN Firewall - FVS336GV2 If you see in the attached config downloaded from VPC (#3 Tunnel Interface Configuration), it gives me some "inside" addresses for the tunnel. When setting up the IPsec tunnels do I use the inside tunnel IP's (e.g. 169.254.254.2/30) or do I use my internal network subnet (10.1.1.0/24) I have tried both, when I tried the local network (10.1.1.x) the tracert stops at the router. When I tried with the "inside" ips, the tracert to the amazon VPC (10.0.0.x) goes out over the internet. this all leads me to the next question, for this router, how do I set up stage #4, the static next hop? What are these seemingly random "inside" addresses and where did amazon generate them from? 169.254.254.x seems odd? With a device like this, is the VPN behind the firewall? I have tweaked any IP addresses below so that they are not "real". I am fully aware, this is probably badly worded. Please if there is any further info/screenshots that will help, let me know.

To limit the impact of this behavior, we recommend the following configuration on your Customer Gateway: - TCP MSS Adjustment : 1387 bytes - Clear Don't Fragment Bit : enabled - Fragmentation : Before encryption #3: Tunnel Interface Configuration Your Customer Gateway must be configured with a tunnel interface that is associated with the IPSec tunnel. All traffic transmitted to the tunnel interface is encrypted and transmitted to the Virtual Private Gateway. The Customer Gateway and Virtual Private Gateway each have two addresses that relate to this IPSec tunnel. Each contains an outside address, upon which encrypted traffic is exchanged. Each also contain an inside address associated with the tunnel interface. The Customer Gateway outside IP address was provided when the Customer Gateway was created. Changing the IP address requires the creation of a new Customer Gateway. The Customer Gateway inside IP address should be configured on your tunnel interface. Outside IP Addresses: - Customer Gateway : 217.33.22.33 - Virtual Private Gateway : 87.222.33.42 Inside IP Addresses - Customer Gateway : 169.254.254.2/30 - Virtual Private Gateway : 169.254.254.1/30 Configure your tunnel to fragment at the optimal size: - Tunnel interface MTU : 1436 bytes #4: Static Routing Configuration: To route traffic between your internal network and your VPC, you will need a static route added to your router.

The VGW will then send traffic towards your internal network over the tunnels. EDIT #1 After writing this post, I continued to fiddle and something started to work, just not very reliably. The local IPs to use when setting up the tunnels where indeed my network subnets. Which further confuses me over what these "inside" IP addresses are for. The problem is, results are not consistent what so ever. I can "sometimes" ping, I can "sometimes" RDP using the VPN. Sometimes, Tunnel 1 or Tunnel 2 can be up or down. When I came back into work today, Tunnel 1 was down, so I deleted it and re-created it from scratch. Now I cant ping anything, but Amazon AND the router are telling me tunnel 1/2 are fine. I guess the router/vpn hardware I have just isnt up to the job..... EDIT #2 Now Tunnel 1 is up, Tunnel 2 is down (I didn't change any settings) and I can ping/rdp again. EDIT #3 Screenshot of route table that the router has built up. Current state (tunnel 1 still up and going string, 2 is still down and wont re-connect)

• Making Thunar the default file browser without hiding the desktop icons

  - by Manu

  I really dislike Ubuntu's default file browser, nautilus, and decided to opt for a lighter alternative (Thunar or Xfe). I've used the following script to change the default to Thunar, but now all my icons are gone from the desktop ! The files are still there, in /home/myid/Desktop, but they do not appear.

• How does one get rid of fishy behavior in Windows?

  - by Tom Wijsman

  After I had boot my computer this morning there suddenly flooded water from the top of the screen, after which some fishes dropped into it. Now I can barely see what I am doing because the water distorts the view. Sometimes the fish follow the cursor so I need to move it away or wait for the fish to mind their own business. This makes it very annoying to use my system. What have I tried? Reboot the system. This caused the water to deplete from the desktop. Upon reboot, the screen was refilled with water and fishes. Attach another monitor. Same problem, fills that monitor as well and gives me extra fish. Clicking the fish. Makes them turn direction. Right clicking the fish. Changes color of the fish, not really useful. I'm locked out of changing the background or screen saver settings. Hence, I had to post the lady below... Safe mode doesn't save me from the fishes. It does give me another background there, but I can't screenshot easily. Other user accounts experience this as well. The Guest account seems to experience more fish than the other accounts. Using HijackThis, OTL Timekeeper List, Syninternal Autoruns, RootKitRevealer, ShellExView and similar tools I can't seem to find any entries that could be it, the Sysinternals tools show everything as verified. I'm suspecting this to be a driver problem. Randomly removing drivers doesn't seem to alleviate the problem. When removing the Graphics Drivers, it makes my screen black. While that could be considered the solution, it's not what I want. Changing the time / date settings does also not seem to affect the fishes. Changing the time a few years in the future, I would have expected the fishes to be dead. But, the same fishes are still there... They simply won't die! Tried to get used to them. They are really bothering me, looks like they require food. I don't know how to give them food, but apparently they get it elsewhere during reboot... Tried to disable my mouse pointer and use the keyboard. This works, they now swim around more randomly. They do put their attention to huge changes on the screen, so I need to type slow. Or otherwise I can't see what I'm tying exactly. Hold my laptop upside down. This seems to affect the water and fishes, but the water stays in the screen. They seem super resistant against water sickness and confusion though... What does the problem look like? What do I need? A way to get rid of these fishes on my screen forever, they are really annoying me a lot and I'm about to crack the screen to see if that makes them escape. Do you have any idea why this problem is occurring? What are my considerations? Buying an USB fish tank could make the fish leave the screen, I am uncertain though whether the fish could leave the screen through the USB cable. Using the FISh (programming language) which seems to provide EXPRESSIVE POWER and EFFICIENT EXECUTION, I can however not find any examples on how to remove fish. What are my Specifications? I'm using a Sony Vaio Fishy laptop. Sony VAIO VGN-Fishy, VAIO. Processor: 1337 MHz, Intel Core 2 Duo, T5432, 1 MB, Intel PM965 Express, 667 MHz.

• Remote host: can tracert, can telnet, can*not* browse: what gives?

  - by MacThePenguin

  One of my customers of the company I work for has made a change to their Internet connection, and now we can't connect to them any more from our LAN. To help me troubleshoot this issue, the network guy on the customer's site has configured their firewall so that a HTTPS connection to their public IP address is open to any IP. I should put https://<customer's IP> in my browser and get a web page. Well, it works from any network I've tried (even from my smartphone), just not from my company's LAN. I thought it may be an issue with our firewall (though I checked its rules and it allows outbound TCP port 443 to anywhere), so I just connected a PC directly to the network connection of our provider, bypassing out firewall completely, and still it didn't work (everything else worked). So I asked for help to our Internet provider's customer service, and they asked me to do a tracert to our customer's IP. The tracert is successful, as the final hop shown in the output is the host I want to reach. So they said there's no problem. :( I also tried telnet <customer's IP> 443 and that works as well: I get a blank page with the cursor blinking (I've tried using another random port and that gives me an error message, as it should). Still, from any browser of any PC in my LAN I can't open that URL. I tried checking the network traffic with Wireshark: I see the packages going through and answers coming back, thought the packets I see passing are far less than they are if I successfully connect to another HTTPS website. See the attached screenshot: I had to blur the IPs, anyway the longer string is my PC's local IP address, the shorter one is the customer's public IP. I don't know what else to try. This is the only IP doing this... Any idea what could I try to find a solution to this issue? Thanks, let me know if you need further details. Edit: when I say "it doesn't work" I mean: the page doesn't open, the browser keeps loading for a long time and eventually shows an error saying that the page cannot be opened. I'm not in my office now so I can't paste the exact message, but it's the usual message you get when the browser reaches its timeout. When I say "it works", I mean the browser loads and shows a webpage (it's the logon page for the customers' firewall admin interface: so there's the firewall brand's logo and there are fields to enter a user id and a password). Update 13/09/2012: tried again to connect to the customer's network through our Internet connection without a firewall. This is what I did: Run a Kubuntu 12.04 live distro on a spare laptop; Updated all the packages I could and installed WireShark; Attached it to my LAN and verified that I couldn't open https://<customer's IP>. Verified that the Wireshark trace for this attempt was the same as the one I've already posted; Verified that I could connect to another customer's host using rdesktop (it worked); Tried to rdesktop to <customer's IP>, here's the output: kubuntu@kubuntu:/etc$ rdesktop <customer's IP> Autoselected keyboard map en-us ERROR: recv: Connection reset by peer Disconnected the laptop from the LAN; Disconnected the firewall from the Extranet connection, connected the laptop instead. Set its network configuration so that I could access the Internet; Verified that I could connect to other websites in http and https and in RDP to other customers' hosts - it all worked as expected; Verified that I could still traceroute to <customer's IP>: I could; Verified that I still couldn't open https://<customer's IP> (same exact result as before); Checked the WireShark trace for this attempt and noticed a different behaviour: I could see packets going out to the customer's IP, but no replies at all; Tried to run rdesktop again, with a slightly different result: kubuntu@kubuntu:/etc/network$ rdesktop <customer's IP> Autoselected keyboard map en-us ERROR: <customer's IP>: unable to connect Finally gave up, put everything back as it was before, turned off the laptop and lost the WireShark traces I had saved. :( I still remember them very well though. :) Can you get anything out of it? Thank you very much. Update 12/09/2012 n.2: I followed the suggestion by MadHatter in the comments. From inside the firewall, this is what I get: user@ubuntu-mantis:~$ openssl s_client -connect <customer's IP>:443 CONNECTED(00000003) If I now type GET / the output pauses for several seconds and then I get: write:errno=104 I'm going to try the same, but bypassing the firewall, as soon as I can. Thanks. Update 12/09/2012 n.3: So, I think ISA Server is altering the results of my tests... I tried installing Wireshark directly on the firewall and monitoring the packets on the Extranet network card. When the destination is the customer's IP, whatever service I try to connect to (HTTPS, RDP or SAProuter), I can only see outbound packets and no response packets whatsoever from their side. It looks like ISA Server is "faking" the remote server's replies, that's why I get a connection using telnet or the openSSL client. This is the wireshark trace from inside our LAN: But this is the trace on the Extranet network card: This makes a bit more sense... I'll send this info to the customer's tech and see if he can make anything out of it. Thanks to all that took the time to read my question and post suggestions. I'll update this post again.

• e2fsck extremly slow, although enough memory exists

  - by kaefert

  I've got this external USB-Disk: kaefert@blechmobil:~$ lsusb -s 2:3 Bus 002 Device 003: ID 0bc2:3320 Seagate RSS LLC As can be seen in this dmesg output, there are some problems that prevents that disk from beeing mounted: kaefert@blechmobil:~$ dmesg | grep sdb [ 114.474342] sd 5:0:0:0: [sdb] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 114.475089] sd 5:0:0:0: [sdb] Write Protect is off [ 114.475092] sd 5:0:0:0: [sdb] Mode Sense: 43 00 00 00 [ 114.475959] sd 5:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 114.477093] sd 5:0:0:0: [sdb] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 114.501649] sdb: sdb1 [ 114.502717] sd 5:0:0:0: [sdb] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 114.504354] sd 5:0:0:0: [sdb] Attached SCSI disk [ 116.804408] EXT4-fs (sdb1): ext4_check_descriptors: Checksum for group 3976 failed (47397!=61519) [ 116.804413] EXT4-fs (sdb1): group descriptors corrupted! So I went and fired up my favorite partition manager - gparted, and told it to verify and repair the partition sdb1. This made gparted call e2fsck (version 1.42.4 (12-Jun-2012)) e2fsck -f -y -v /dev/sdb1 Although gparted called e2fsck with the "-v" option, sadly it doesn't show me the output of my e2fsck process (bugreport https://bugzilla.gnome.org/show_bug.cgi?id=467925 ) I started this whole thing on Sunday (2012-11-04_2200) evening, so about 48 hours ago, this is what htop says about it now (2012-11-06-1900): PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 3704 root 39 19 1560M 1166M 768 R 98.0 19.5 42h56:43 e2fsck -f -y -v /dev/sdb1 Now I found a few posts on the internet that discuss e2fsck running slow, for example: http://gparted-forum.surf4.info/viewtopic.php?id=13613 where they write that its a good idea to see if the disk is just that slow because maybe its damaged, and I think these outputs tell me that this is not the case in my case: kaefert@blechmobil:~$ sudo hdparm -tT /dev/sdb /dev/sdb: Timing cached reads: 3562 MB in 2.00 seconds = 1783.29 MB/sec Timing buffered disk reads: 82 MB in 3.01 seconds = 27.26 MB/sec kaefert@blechmobil:~$ sudo hdparm /dev/sdb /dev/sdb: multcount = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 364801/255/63, sectors = 5860533160, start = 0 However, although I can read quickly from that disk, this disk speed doesn't seem to be used by e2fsck, considering tools like gkrellm or iotop or this: kaefert@blechmobil:~$ iostat -x Linux 3.2.0-2-amd64 (blechmobil) 2012-11-06 _x86_64_ (2 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 14,24 47,81 14,63 0,95 0,00 22,37 Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sda 0,59 8,29 2,42 5,14 43,17 160,17 53,75 0,30 39,80 8,72 54,42 3,95 2,99 sdb 137,54 5,48 9,23 0,20 587,07 22,73 129,35 0,07 7,70 7,51 16,18 2,17 2,04 Now I researched a little bit on how to find out what e2fsck is doing with all that processor time, and I found the tool strace, which gives me this: kaefert@blechmobil:~$ sudo strace -p3704 lseek(4, 41026998272, SEEK_SET) = 41026998272 write(4, "\212\354K[_\361\3nl\212\245\352\255jR\303\354\312Yv\334p\253r\217\265\3567\325\257\3766"..., 4096) = 4096 lseek(4, 48404766720, SEEK_SET) = 48404766720 read(4, "\7t\260\366\346\337\304\210\33\267j\35\377'\31f\372\252\ffU\317.y\211\360\36\240c\30`\34"..., 4096) = 4096 lseek(4, 41027002368, SEEK_SET) = 41027002368 write(4, "\232]7Ws\321\352\t\1@[+5\263\334\276{\343zZx\352\21\316`1\271[\202\350R`"..., 4096) = 4096 lseek(4, 48404770816, SEEK_SET) = 48404770816 read(4, "\17\362r\230\327\25\346//\210H\v\311\3237\323K\304\306\361a\223\311\324\272?\213\tq \370\24"..., 4096) = 4096 lseek(4, 41027006464, SEEK_SET) = 41027006464 write(4, "\367yy>x\216?=\324Z\305\351\376&\25\244\210\271\22\306}\276\237\370(\214\205G\262\360\257#"..., 4096) = 4096 lseek(4, 48404774912, SEEK_SET) = 48404774912 read(4, "\365\25\0\21|T\0\21}3t_\272\373\222k\r\177\303\1\201\261\221$\261B\232\3142\21U\316"..., 4096) = 4096 ^CProcess 3704 detached around 16 of these lines every second, so 4 read and 4 write operations every second, which I don't consider to be a lot.. And finally, my question: Will this process ever finish? If those numbers from fseek (48404774912) represent bytes, that would be something like 45 gigabytes, with this beeing a 3 terrabyte disk, which would give me 134 days to go, if the speed stays constant, and he scans the disk like this completly and only once. Do you have some advice for me? I have most of the data on that disk elsewhere, but I've put a lot of hours into sorting and merging it to this disk, so I would prefer to getting this disk up and running again, without formatting it anew. I don't think that the hardware is damaged since the disk is only a few months and since I can't see any I/O errors in the dmesg output. UPDATE: I just looked at the strace output again (2012-11-06_2300), now it looks like this: lseek(4, 1419860611072, SEEK_SET) = 1419860611072 read(4, "3#\f\2447\335\0\22A\355\374\276j\204'\207|\217V|\23\245[\7VP\251\242\276\207\317:"..., 4096) = 4096 lseek(4, 43018145792, SEEK_SET) = 43018145792 write(4, "]\206\231\342Y\204-2I\362\242\344\6R\205\361\324\177\265\317C\334V\324\260\334\275t=\10F."..., 4096) = 4096 lseek(4, 1419860615168, SEEK_SET) = 1419860615168 read(4, "\262\305\314Y\367\37x\326\245\226\226\320N\333$s\34\204\311\222\7\315\236\336\300TK\337\264\236\211n"..., 4096) = 4096 lseek(4, 43018149888, SEEK_SET) = 43018149888 write(4, "\271\224m\311\224\25!I\376\16;\377\0\223H\25Yd\201Y\342\r\203\271\24eG<\202{\373V"..., 4096) = 4096 lseek(4, 1419860619264, SEEK_SET) = 1419860619264 read(4, ";d\360\177\n\346\253\210\222|\250\352T\335M\33\260\320\261\7g\222P\344H?t\240\20\2548\310"..., 4096) = 4096 lseek(4, 43018153984, SEEK_SET) = 43018153984 write(4, "\360\252j\317\310\251G\227\335{\214`\341\267\31Y\202\360\v\374\307oq\3063\217Z\223\313\36D\211"..., 4096) = 4096 So this number of the lseeks before the reads, like 1419860619264 are already a lot bigger, standing for 1.29 terabytes if the numbers are bytes, so it doesn't seem to be a linear progress on a big scale, maybe there are only some areas that need work, that have big gaps in between them.

• Need help with Android TableLayout alignment

  - by Ben L.

  I'm trying to build a calculator layout using TableLayout, but the last two rows aren't aligning with the rest of the layout. Is there something wrong with my layout XML? What I'm trying to do would be easier to accomplish in HTML (<td> with colspan or rowspan), so should I try converting this into a WebView? Code is as follows: (Screenshot) <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" /> <TableLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:stretchColumns="*"> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <Button android:id="@+id/Button08" android:textSize="16pt" android:text="^" android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="wrap_content" /> <Button android:id="@+id/Button09" android:text="÷" android:textSize="16pt" android:layout_height="fill_parent" android:layout_weight="1" android:layout_width="wrap_content" /> <Button android:id="@+id/Button10" android:text="×" android:textSize="16pt" android:layout_height="fill_parent" android:layout_weight="1" android:layout_width="wrap_content" /> <Button android:id="@+id/Button11" android:textSize="16pt" android:text="-" android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="wrap_content" /> </TableRow> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="2"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1"> <Button android:id="@+id/Button01" android:text="7" android:textSize="16pt" android:layout_weight="1" android:layout_height="wrap_content" android:layout_width="fill_parent" /> <Button android:layout_height="wrap_content" android:textSize="16pt" android:text="4" android:id="@+id/Button05" android:layout_weight="1" android:layout_width="fill_parent" /> </LinearLayout> <LinearLayout android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:layout_width="fill_parent"> <Button android:id="@+id/Button02" android:layout_height="wrap_content" android:text="8" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" /> <Button android:layout_height="wrap_content" android:textSize="16pt" android:text="5" android:id="@+id/Button06" android:layout_weight="1" android:layout_width="fill_parent" /> </LinearLayout> <LinearLayout android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1" android:layout_width="fill_parent"> <Button android:id="@+id/Button03" android:text="9" android:textSize="16pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" /> <Button android:textSize="16pt" android:text="6" android:id="@+id/Button07" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" /> </LinearLayout> <Button android:id="@+id/Button04" android:text="+" android:textSize="16pt" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1" /> </TableRow> <TableRow android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="2"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="2"> <LinearLayout android:layout_weight="1" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/Button02" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="1" /> <Button android:textSize="16pt" android:id="@+id/Button06" android:layout_weight="1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="2" /> </LinearLayout> <Button android:id="@+id/Button01" android:layout_height="wrap_content" android:textSize="16pt" android:layout_weight="1" android:layout_width="fill_parent" android:text="0" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_weight="1"> <Button android:id="@+id/Button03" android:textSize="16pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="3" /> <Button android:textSize="16pt" android:id="@+id/Button07" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="." /> </LinearLayout> <Button android:id="@+id/Button04" android:textSize="16pt" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1" android:text="=" /> </TableRow> </TableLayout> </LinearLayout>

• Parse JSON in C#

  - by Ender

  I'm trying to parse some JSON data from the Google AJAX Search API. I have this URL and I'd like to break it down so that the results are displayed. I've currently written this code, but I'm pretty lost in regards of what to do next, although there are a number of examples out there with simplified JSON strings. Being new to C# and .NET in general I've struggled to get a genuine text output for my ASP.NET page so I've been recommended to give JSON.NET a try. Could anyone point me in the right direction to just simply writing some code that'll take in JSON from the Google AJAX Search API and print it out to the screen? EDIT: I think I've made some progress in regards to getting some code working using DataContractJsonSerializer. Here is the code I have so far. Any advice on whether this is close to working and/or how I would output my results in a clean format? EDIT 2: I've followed the advice from Dreas Grech and the StackOverflowException has gone. However, now I am getting no output. Any ideas on where to go next? EDIT 3: ALL FIXED! All results are working fine.

• 500 - An error has occurred! DB function reports no errors when adding new article in Joomla!

  - by Roland

  I have an article that I want to publish on my Joomla! site. Every time I click apply or save. I get error 500 - An error has occurred! DB function reports no errors. I have no idea why this error comes up, al I can think is that it's a server error. I'm using TinyMCE to type articles together with Joomla! 1.5.11. Updated: I turned on Maximum error reporting in Joomla! and in the article manager I tried to save the article and got these couple of errors. Please check screenshot I tried adding <?php ini_set('error_reporting', E_ALL); error_reporting(E_ALL); ini_set('log_errors',TRUE); ini_set('html_errors',TRUE); ini_set('display_errors',true); ?> at the top of the index.php pages for Joomla! but it does not show any errors. I checked the error logs on the server and also no errors come up. I managed to publish the article via phpMyAdmin but then something else happens. I try to access to article from the front end, by clicking on the link to the article, but only a blank page comes up. This is really weird, since the error log does not show any information. So I assume the error needs to be coming from Joomla! This happens if I add a print_r($_POST) before if (!$row->check()) { on /administrator/components/com_content/controller.php (around line 693) Array ( [title] => Test. [state] => 0 [alias] => test [frontpage] => 0 [sectionid] => 10 [catid] => 44 [details] => Array ( [created_by] => 62 [created_by_alias] => [access] => 0 [created] => 2008-10-25 13:31:21 [publish_up] => 2008-10-25 13:31:21 [publish_down] => Never ) [params] => Array ( [show_title] => [link_titles] => [show_intro] => [show_section] => [link_section] => [show_category] => [link_category] => [show_vote] => [show_author] => 1 [show_create_date] => 0 [show_modify_date] => 0 [show_pdf_icon] => [show_print_icon] => [show_email_icon] => [language] => [keyref] => [readmore] => ) [meta] => Array ( [description] => Test.

• Drools flow architecture, Drools flow events with AND join nodes

  - by Shoukry K

  I have been evaluating a number of frameworks including jBPM and Drools flow for my application requirements. Lots of the opinions seem to be inclined towards Drools flow as its more flexible, knowledge oriented, easier to integrate with business rules, etc.. The application is some sort of an Email Campaign manager , where different customers can sign in, prepare (design) and launch email campaigns. The application should be able to do the following : 1- Receive a list of email addresses, send emails to each of these addresses starting from a certain date and during a certain time interval of the day , do some custom actions, and then wait for reply emails. 2- If a reply email is received and depending on the response text of the email , and depending on the time the email was received certain actions need to happen, web service calls need to take place, and error handling for these calls. 3- The application will manage and run many and different campaigns (different customers and different flows for each customer) at any point of time. The first question is : Is Drools flow the way to go about this? My main concerns are scalability, suspending, resuming flows, and long wait, and flows management. As you see from the requirements : There is a scheduling part : Certain flows need to be run at a certain point in time, they need to get suspended and then resumed. For example start sending emails starting on Dec 1st 2010 and send emails only in the time interval between 08:00 and 17:00 GMT. By then it might be that all subscribers have been sent emails, but it might not be the case, the process needs to (resume) on Dec 2nd and send a second batch, however certain (users) already received emails and they should be able to (continue at different stages of the flow) There are long wait states : Days or even weeks , i need to persist, suspend / resume and terminate flows (manage flows) External Events : This is where i got stuck first, i tried to put together a simple flow (see attached screenshot) See image http://img46.imageshack.us/img46/9620/workflowwithevents.png , there is a start node , connected to an action node, connected to a join. An event node is connected to a second action node, which is connected to the join. The join is an AND join , after the join there is an action and the end node. Here is the sample code i am using to launch the flow : KnowledgeBuilder builder = KnowledgeBuilderFactory .newKnowledgeBuilder(); builder.add(ResourceFactory.newClassPathResource("campaign.rf", CampaignsDroolsPoc.class), ResourceType.DRF); if (builder.hasErrors()) { KnowledgeBuilderErrors errors = builder.getErrors(); Iterator<KnowledgeBuilderError> iterator = errors.iterator(); while (iterator.hasNext()) { System.out.println(iterator.next().toString()); } } KnowledgeBase base = KnowledgeBaseFactory.newKnowledgeBase(); base.addKnowledgePackages(builder.getKnowledgePackages()); final StatefulKnowledgeSession ksession = base .newStatefulKnowledgeSession(); // KnowledgeRuntimeLoggerFactory.newConsoleLogger(ksession); ksession.getWorkItemManager().registerWorkItemHandler("Log", new SendSMSWorkItemHandler()); ProcessInstance startProcess = ksession.startProcess("flow"); System.out.println("Signaling event"); startProcess.signalEvent("ev1", "ev1"); System.out.println("Signaled"); ksession.fireUntilHalt(); I am noticing that the event get triggered, the action node connected to the event gets triggered, however things seem to get stuck at the join. The flow does not continue past the AND join and the flow seems to get stuck. The action following the node does not get triggered. I also went through the drools flow documentation , and all the example codes, however i didn't find anything there. In addition any hints about the way to go about architecting the solution, and implementing it would be great.

• UI android question/problem with Listview

  - by user309554

  Hi, I'm trying to recreate the UI screen called 'My Places' that is used in the Weather Channel app. I'd attach a screenshot of the screen, but I can't seem to do it here. It seems they're using two listviews one on top of the other, but I'm not sure for certain. Could anybody confirm this for me? If they are doing this, how is this done? I've tried to implement this, but without full success. My top listview 'Add a place' 'comes up correctly, but the bottom listview will not appear/populate for me? I shall attach my code so far...... Any help would be greatly appreciated. Thanks Simon header_row.xml ?xml version="1.0" encoding="utf-8"?

• Mysql - Help me change this single complex query to use temporary tables

  - by sandeepan-nath

  About the system: - There are tutors who create classes and packs - A tags based search approach is being followed.Tag relations are created when new tutors register and when tutors create packs (this makes tutors and packs searcheable). For details please check the section How tags work in this system? below. Following is the concerned query Can anybody help me suggest an approach using temporary tables. We have indexed all the relevant fields and it looks like this is the least time possible with this approach:- SELECT SUM(DISTINCT( t.tag LIKE "%Dictatorship%" OR tt.tag LIKE "%Dictatorship%" OR ttt.tag LIKE "%Dictatorship%" )) AS key_1_total_matches , SUM(DISTINCT( t.tag LIKE "%democracy%" OR tt.tag LIKE "%democracy%" OR ttt.tag LIKE "%democracy%" )) AS key_2_total_matches , COUNT(DISTINCT( od.id_od )) AS tutor_popularity, CASE WHEN ( IF(( wc.id_wc > 0 ), ( wc.wc_api_status = 1 AND wc.wc_type = 0 AND wc.class_date > '2010-06-01 22:00:56' AND wccp.status = 1 AND ( wccp.country_code = 'IE' OR wccp.country_code IN ( 'INT' ) ) ), 0) ) THEN 1 ELSE 0 END AS 'classes_published' , CASE WHEN ( IF(( lp.id_lp > 0 ), ( lp.id_status = 1 AND lp.published = 1 AND lpcp.status = 1 AND ( lpcp.country_code = 'IE' OR lpcp.country_code IN ( 'INT' ) ) ), 0) ) THEN 1 ELSE 0 END AS 'packs_published', td . *, u . * FROM tutor_details AS td JOIN users AS u ON u.id_user = td.id_user LEFT JOIN learning_packs_tag_relations AS lptagrels ON td.id_tutor = lptagrels.id_tutor LEFT JOIN learning_packs AS lp ON lptagrels.id_lp = lp.id_lp LEFT JOIN learning_packs_categories AS lpc ON lpc.id_lp_cat = lp.id_lp_cat LEFT JOIN learning_packs_categories AS lpcp ON lpcp.id_lp_cat = lpc.id_parent LEFT JOIN learning_pack_content AS lpct ON ( lp.id_lp = lpct.id_lp ) LEFT JOIN webclasses_tag_relations AS wtagrels ON td.id_tutor = wtagrels.id_tutor LEFT JOIN webclasses AS wc ON wtagrels.id_wc = wc.id_wc LEFT JOIN learning_packs_categories AS wcc ON wcc.id_lp_cat = wc.id_wp_cat LEFT JOIN learning_packs_categories AS wccp ON wccp.id_lp_cat = wcc.id_parent LEFT JOIN order_details AS od ON td.id_tutor = od.id_author LEFT JOIN orders AS o ON od.id_order = o.id_order LEFT JOIN tutors_tag_relations AS ttagrels ON td.id_tutor = ttagrels.id_tutor LEFT JOIN tags AS t ON t.id_tag = ttagrels.id_tag LEFT JOIN tags AS tt ON tt.id_tag = lptagrels.id_tag LEFT JOIN tags AS ttt ON ttt.id_tag = wtagrels.id_tag WHERE ( u.country = 'IE' OR u.country IN ( 'INT' ) ) AND CASE WHEN ( ( tt.id_tag = lptagrels.id_tag ) AND ( lp.id_lp > 0 ) ) THEN lp.id_status = 1 AND lp.published = 1 AND lpcp.status = 1 AND ( lpcp.country_code = 'IE' OR lpcp.country_code IN ( 'INT' ) ) ELSE 1 END AND CASE WHEN ( ( ttt.id_tag = wtagrels.id_tag ) AND ( wc.id_wc > 0 ) ) THEN wc.wc_api_status = 1 AND wc.wc_type = 0 AND wc.class_date > '2010-06-01 22:00:56' AND wccp.status = 1 AND ( wccp.country_code = 'IE' OR wccp.country_code IN ( 'INT' ) ) ELSE 1 END AND CASE WHEN ( od.id_od > 0 ) THEN od.id_author = td.id_tutor AND o.order_status = 'paid' AND CASE WHEN ( od.id_wc > 0 ) THEN od.can_attend_class = 1 ELSE 1 END ELSE 1 END AND ( t.tag LIKE "%Dictatorship%" OR t.tag LIKE "%democracy%" OR tt.tag LIKE "%Dictatorship%" OR tt.tag LIKE "%democracy%" OR ttt.tag LIKE "%Dictatorship%" OR ttt.tag LIKE "%democracy%" ) GROUP BY td.id_tutor HAVING key_1_total_matches = 1 AND key_2_total_matches = 1 ORDER BY tutor_popularity DESC, u.surname ASC, u.name ASC LIMIT 0, 20 The problem The results returned by the above query are correct (AND logic working as per expectation), but the time taken by the query rises alarmingly for heavier data and for the current data I have it is like 10 seconds as against normal query timings of the order of 0.005 - 0.0002 seconds, which makes it totally unusable. Somebody suggested in my previous question to do the following:- create a temporary table and insert here all relevant data that might end up in the final result set run several updates on this table, joining the required tables one at a time instead of all of them at the same time finally perform a query on this temporary table to extract the end result All this was done in a stored procedure, the end result has passed unit tests, and is blazing fast. I have never worked with temporary tables till now. Only if I could get some hints, kind of schematic representations so that I can start with... Is there something faulty with the query? What can be the reason behind 10+ seconds of execution time? How tags work in this system? When a tutor registers, tags are entered and tag relations are created with respect to tutor's details like name, surname etc. When a Tutors create packs, again tags are entered and tag relations are created with respect to pack's details like pack name, description etc. tag relations for tutors stored in tutors_tag_relations and those for packs stored in learning_packs_tag_relations. All individual tags are stored in tags table. The explain query output:- Please see this screenshot - http://www.test.examvillage.com/Explain_query_improved.jpg

• Problem with Freetype and OpenGL

  - by Morgan

  Hey, i'm having a weird issue with drawing text in openGL loaded with the Freetype 2 library. Here is a screenshot of what I'm seeing. http://img203.imageshack.us/img203/3316/freetypeweird.png Here are my code bits for loading and rendering my text. class Font { Font(const String& filename) { if (FT_New_Face(Font::ftLibrary, "arial.ttf", 0, &mFace)) { cout << "UH OH!" << endl; } FT_Set_Char_Size(mFace, 16 * 64, 16 * 64, 72, 72); } Glyph* GetGlyph(const unsigned char ch) { if(FT_Load_Char(mFace, ch, FT_LOAD_RENDER)) cout << "OUCH" << endl; FT_Glyph glyph; if(FT_Get_Glyph( mFace->glyph, &glyph )) cout << "OUCH" << endl; FT_BitmapGlyph bitmap_glyph = (FT_BitmapGlyph)glyph; Glyph* thisGlyph = new Glyph; thisGlyph->buffer = bitmap_glyph->bitmap.buffer; thisGlyph->width = bitmap_glyph->bitmap.width; thisGlyph->height = bitmap_glyph->bitmap.rows; return thisGlyph; } }; The relevant glyph information (width, height, buffer) is stored in the following struct struct Glyph { GLubyte* buffer; Uint width; Uint height; }; And finally, to render it, I have this class called RenderFont. class RenderFont { RenderFont(Font* font) { mTextureIds = new GLuint[128]; mFirstDisplayListId=glGenLists(128); glGenTextures( 128, mTextureIds ); for(unsigned char i=0;i<128;i++) { MakeDisplayList(font, i); } } void MakeDisplayList(Font* font, unsigned char ch) { Glyph* glyph = font->GetGlyph(ch); glBindTexture( GL_TEXTURE_2D, mTextureIds[ch]); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, glyph->width, glyph->height, 0, GL_ALPHA, GL_UNSIGNED_BYTE, glyph->buffer); glNewList(mFirstDisplayListId+ch,GL_COMPILE); glBindTexture(GL_TEXTURE_2D, mTextureIds[ch]); glBegin(GL_QUADS); glTexCoord2d(0,1); glVertex2f(0,glyph->height); glTexCoord2d(0,0); glVertex2f(0,0); glTexCoord2d(1,0); glVertex2f(glyph->width,0); glTexCoord2d(1,1); glVertex2f(glyph->width,glyph->height); glEnd(); glTranslatef(16, 0, 0); glEndList(); } void Draw(const String& text, Uint size, const TransformComponent* transform, const Color32* color) { glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glTranslatef(100, 250, 0.0f); glListBase(mFirstDisplayListId); glCallLists(text.length(), GL_UNSIGNED_BYTE, text.c_str()); glDisable(GL_TEXTURE_2D); glDisable(GL_BLEND); glLoadIdentity(); } private: GLuint mFirstDisplayListId; GLuint* mTextureIds; }; Can anybody see anything weird going on here that would cause the garbled text? It's strange because if I change the font size, or the DPI, then some of the letters that display correctly become garbled, and other letters that were garbled before then display correctly.
