  • Ardour wont start Jack problem

    - by Drew S
    I downloaded Ardour yesterday, it worked, edited an audio file done. Come back today it wont start I get this: Ardour could not start JACK There are several possible reasons: 1) You requested audio parameters that are not supported.. 2) JACK is running as another user. Please consider the possibilities, and perhaps try different parameters. So I try and look at qjackctl to see what happening there. When I try to start JACK I get D-BUS: JACK server could not be started. then Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info. and this is the message box in JACK. 15:22:12.927 Patchbay deactivated. 15:22:12.927 Statistics reset. 15:22:12.944 ALSA connection change. 15:22:12.951 D-BUS: Service is available (org.jackaudio.service aka jackdbus).

  • Android source code not working, reading frame buffer through glReadPixels

    - by Muhammad Ali Rajput
    Hi, I am new to Android development and have an assignment to read frame buffer data after a specified interval of time. I have come up with the following code: public class mainActivity extends Activity { Bitmap mSavedBM; private EGL10 egl; private EGLDisplay display; private EGLConfig config; private EGLSurface surface; private EGLContext eglContext; private GL11 gl; protected int width, height; //Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // get the screen width and height DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); int screenWidth = dm.widthPixels; int screenHeight = dm.heightPixels; String SCREENSHOT_DIR = "/screenshots"; initGLFr(); //GlView initialized. savePixels( 0, 10, screenWidth, screenHeight, gl); //this gets the screen to the mSavedBM. saveBitmap(mSavedBM, SCREENSHOT_DIR, "capturedImage"); //Now we need to save the bitmap (the screen capture) to some location. setContentView(R.layout.main); //This displays the content on the screen } private void initGLFr() { egl = (EGL10) EGLContext.getEGL(); display = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY); int[] ver = new int[2]; egl.eglInitialize(display, ver); int[] configSpec = {EGL10.EGL_NONE}; EGLConfig[] configOut = new EGLConfig[1]; int[] nConfig = new int[1]; egl.eglChooseConfig(display, configSpec, configOut, 1, nConfig); config = configOut[0]; eglContext = egl.eglCreateContext(display, config, EGL10.EGL_NO_CONTEXT, null); surface = egl.eglCreateWindowSurface(display, config, SurfaceHolder.SURFACE_TYPE_GPU, null); egl.eglMakeCurrent(display, surface, surface, eglContext); gl = (GL11) eglContext.getGL(); } public void savePixels(int x, int y, int w, int h, GL10 gl) { if (gl == null) return; synchronized (this) { if (mSavedBM != null) { mSavedBM.recycle(); mSavedBM = null; } } int b[] = new int[w * (y + h)]; int bt[] = new int[w * h]; IntBuffer ib = IntBuffer.wrap(b); ib.position(0); gl.glReadPixels(x, 0, w, y + h, GL10.GL_RGBA,GL10.GL_UNSIGNED_BYTE,ib); for (int i = 0, k = 0; i < h; i++, k++) { //OpenGLbitmap is incompatible with Android bitmap //and so, some corrections need to be done. for (int j = 0; j < w; j++) { int pix = b[i * w + j]; int pb = (pix >> 16) & 0xff; int pr = (pix << 16) & 0x00ff0000; int pix1 = (pix & 0xff00ff00) | pr | pb; bt[(h - k - 1) * w + j] = pix1; } } Bitmap sb = Bitmap.createBitmap(bt, w, h, Bitmap.Config.ARGB_8888); synchronized (this) { mSavedBM = sb; } } static String saveBitmap(Bitmap bitmap, String dir, String baseName) { try { File sdcard = Environment.getExternalStorageDirectory(); File pictureDir = new File(sdcard, dir); pictureDir.mkdirs(); File f = null; for (int i = 1; i < 200; ++i) { String name = baseName + i + ".png"; f = new File(pictureDir, name); if (!f.exists()) { break; } } if (!f.exists()) { String name = f.getAbsolutePath(); FileOutputStream fos = new FileOutputStream(name); bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos); fos.flush(); fos.close(); return name; } } catch (Exception e) { } finally { //if (fos != null) { // fos.close(); // } } return null; } } Also, if some one can direct me to better way to read the framebuffer it would be great. I am using Android 2.2 and virtual device of API level 8. I have gone through many previous discussions and have found that we can not know read frame buffer directly throuh the "/dev/graphics/fb0". Thanks, Muhammad Ali

  • Setting useLegacyV2RuntimeActivationPolicy At Runtime

    - by Reed
    Version 4.0 of the .NET Framework included a new CLR which is almost entirely backwards compatible with the 2.0 version of the CLR.  However, by default, mixed-mode assemblies targeting .NET 3.5sp1 and earlier will fail to load in a .NET 4 application.  Fixing this requires setting useLegacyV2RuntimeActivationPolicy in your app.Config for the application.  While there are many good reasons for this decision, there are times when this is extremely frustrating, especially when writing a library.  As such, there are (rare) times when it would be beneficial to set this in code, at runtime, as well as verify that it’s running correctly prior to receiving a FileLoadException. Typically, loading a pre-.NET 4 mixed mode assembly is handled simply by changing your app.Config file, and including the relevant attribute in the startup element: <?xml version="1.0" encoding="utf-8" ?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> .csharpcode { background-color: #ffffff; font-family: consolas, "Courier New", courier, monospace; color: black; font-size: small } .csharpcode pre { background-color: #ffffff; font-family: consolas, "Courier New", courier, monospace; color: black; font-size: small } .csharpcode pre { margin: 0em } .csharpcode .rem { color: #008000 } .csharpcode .kwrd { color: #0000ff } .csharpcode .str { color: #006080 } .csharpcode .op { color: #0000c0 } .csharpcode .preproc { color: #cc6633 } .csharpcode .asp { background-color: #ffff00 } .csharpcode .html { color: #800000 } .csharpcode .attr { color: #ff0000 } .csharpcode .alt { background-color: #f4f4f4; margin: 0em; width: 100% } .csharpcode .lnum { color: #606060 } This causes your application to run correctly, and load the older, mixed-mode assembly without issues. For full details on what’s happening here and why, I recommend reading Mark Miller’s detailed explanation of this attribute and the reasoning behind it. Before I show any code, let me say: I strongly recommend using the official approach of using app.config to set this policy. That being said, there are (rare) times when, for one reason or another, changing the application configuration file is less than ideal. While this is the supported approach to handling this issue, the CLR Hosting API includes a means of setting this programmatically via the ICLRRuntimeInfo interface.  Normally, this is used if you’re hosting the CLR in a native application in order to set this, at runtime, prior to loading the assemblies.  However, the F# Samples include a nice trick showing how to load this API and bind this policy, at runtime.  This was required in order to host the Managed DirectX API, which is built against an older version of the CLR. This is fairly easy to port to C#.  Instead of a direct port, I also added a little addition – by trapping the COM exception received if unable to bind (which will occur if the 2.0 CLR is already bound), I also allow a runtime check of whether this property was setup properly: public static class RuntimePolicyHelper { public static bool LegacyV2RuntimeEnabledSuccessfully { get; private set; } static RuntimePolicyHelper() { ICLRRuntimeInfo clrRuntimeInfo = (ICLRRuntimeInfo)RuntimeEnvironment.GetRuntimeInterfaceAsObject( Guid.Empty, typeof(ICLRRuntimeInfo).GUID); try { clrRuntimeInfo.BindAsLegacyV2Runtime(); LegacyV2RuntimeEnabledSuccessfully = true; } catch (COMException) { // This occurs with an HRESULT meaning // "A different runtime was already bound to the legacy CLR version 2 activation policy." LegacyV2RuntimeEnabledSuccessfully = false; } } [ComImport] [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] [Guid("BD39D1D2-BA2F-486A-89B0-B4B0CB466891")] private interface ICLRRuntimeInfo { void xGetVersionString(); void xGetRuntimeDirectory(); void xIsLoaded(); void xIsLoadable(); void xLoadErrorString(); void xLoadLibrary(); void xGetProcAddress(); void xGetInterface(); void xSetDefaultStartupFlags(); void xGetDefaultStartupFlags(); [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)] void BindAsLegacyV2Runtime(); } } Using this, it’s possible to not only set this at runtime, but also verify, prior to loading your mixed mode assembly, whether this will succeed. In my case, this was quite useful – I am working on a library purely for internal use which uses a numerical package that is supplied with both a completely managed as well as a native solver.  The native solver uses a CLR 2 mixed-mode assembly, but is dramatically faster than the pure managed approach.  By checking RuntimePolicyHelper.LegacyV2RuntimeEnabledSuccessfully at runtime, I can decide whether to enable the native solver, and only do so if I successfully bound this policy. There are some tricks required here – To enable this sort of fallback behavior, you must make these checks in a type that doesn’t cause the mixed mode assembly to be loaded.  In my case, this forced me to encapsulate the library I was using entirely in a separate class, perform the check, then pass through the required calls to that class.  Otherwise, the library will load before the hosting process gets enabled, which in turn will fail. This code will also, of course, try to enable the runtime policy before the first time you use this class – which typically means just before the first time you check the boolean value.  As a result, checking this early on in the application is more likely to allow it to work. Finally, if you’re using a library, this has to be called prior to the 2.0 CLR loading.  This will cause it to fail if you try to use it to enable this policy in a plugin for most third party applications that don’t have their app.config setup properly, as they will likely have already loaded the 2.0 runtime. As an example, take a simple audio player.  The code below shows how this can be used to properly, at runtime, only use the “native” API if this will succeed, and fallback (or raise a nicer exception) if this will fail: public class AudioPlayer { private IAudioEngine audioEngine; public AudioPlayer() { if (RuntimePolicyHelper.LegacyV2RuntimeEnabledSuccessfully) { // This will load a CLR 2 mixed mode assembly this.audioEngine = new AudioEngineNative(); } else { this.audioEngine = new AudioEngineManaged(); } } public void Play(string filename) { this.audioEngine.Play(filename); } } Now – the warning: This approach works, but I would be very hesitant to use it in public facing production code, especially for anything other than initializing your own application.  While this should work in a library, using it has a very nasty side effect: you change the runtime policy of the executing application in a way that is very hidden and non-obvious.

  • elffile: ELF Specific File Identification Utility

    - by user9154181
    Solaris 11 has a new standard user level command, /usr/bin/elffile. elffile is a variant of the file utility that is focused exclusively on linker related files: ELF objects, archives, and runtime linker configuration files. All other files are simply identified as "non-ELF". The primary advantage of elffile over the existing file utility is in the area of archives — elffile examines the archive members and can produce a summary of the contents, or per-member details. The impetus to add elffile to Solaris came from the effort to extend the format of Solaris archives so that they could grow beyond their previous 32-bit file limits. That work introduced a new archive symbol table format. Now that there was more than one possible format, I thought it would be useful if the file utility could identify which format a given archive is using, leading me to extend the file utility: % cc -c ~/hello.c % ar r foo.a hello.o % file foo.a foo.a: current ar archive, 32-bit symbol table % ar r -S foo.a hello.o % file foo.a foo.a: current ar archive, 64-bit symbol table In turn, this caused me to think about all the things that I would like the file utility to be able to tell me about an archive. In particular, I'd like to be able to know what's inside without having to unpack it. The end result of that train of thought was elffile. Much of the discussion in this article is adapted from the PSARC case I filed for elffile in December 2010: PSARC 2010/432 elffile Why file Is No Good For Archives And Yet Should Not Be Fixed The standard /usr/bin/file utility is not very useful when applied to archives. When identifying an archive, a user typically wants to know 2 things: Is this an archive? Presupposing that the archive contains objects, which is by far the most common use for archives, what platform are the objects for? Are they for sparc or x86? 32 or 64-bit? Some confusing combination from varying platforms? The file utility provides a quick answer to question (1), as it identifies all archives as "current ar archive". It does nothing to answer the more interesting question (2). To answer that question, requires a multi-step process: Extract all archive members Use the file utility on the extracted files, examine the output for each file in turn, and compare the results to generate a suitable summary description. Remove the extracted files It should be easier and more efficient to answer such an obvious question. It would be reasonable to extend the file utility to examine archive contents in place and produce a description. However, there are several reasons why I decided not to do so: The correct design for this feature within the file utility would have file examine each archive member in turn, applying its full abilities to each member. This would be elegant, but also represents a rather dramatic redesign and re-implementation of file. Archives nearly always contain nothing but ELF objects for a single platform, so such generality in the file utility would be of little practical benefit. It is best to avoid adding new options to standard utilities for which other implementations of interest exist. In the case of the file utility, one concern is that we might add an option which later appears in the GNU version of file with a different and incompatible meaning. Indeed, there have been discussions about replacing the Solaris file with the GNU version in the past. This may or may not be desirable, and may or may not ever happen. Either way, I don't want to preclude it. Examining archive members is an O(n) operation, and can be relatively slow with large archives. The file utility is supposed to be a very fast operation. I decided that extending file in this way is overkill, and that an investment in the file utility for better archive support would not be worth the cost. A solution that is more narrowly focused on ELF and other linker related files is really all that we need. The necessary code for doing this already exists within libelf. All that is missing is a small user-level wrapper to make that functionality available at the command line. In that vein, I considered adding an option for this to the elfdump utility. I examined elfdump carefully, and even wrote a prototype implementation. The added code is small and simple, but the conceptual fit with the rest of elfdump is poor. The result complicates elfdump syntax and documentation, definite signs that this functionality does not belong there. And so, I added this functionality as a new user level command. The elffile Command The syntax for this new command is elffile [-s basic | detail | summary] filename... Please see the elffile(1) manpage for additional details. To demonstrate how output from elffile looks, I will use the following files: FileDescription configA runtime linker configuration file produced with crle dwarf.oAn ELF object /etc/passwdA text file mixed.aArchive containing a mixture of ELF and non-ELF members mixed_elf.aArchive containing ELF objects for different machines not_elf.aArchive containing no ELF objects same_elf.aArchive containing a collection of ELF objects for the same machine. This is the most common type of archive. The file utility identifies these files as follows: % file config dwarf.o /etc/passwd mixed.a mixed_elf.a not_elf.a same_elf.a config: Runtime Linking Configuration 64-bit MSB SPARCV9 dwarf.o: ELF 64-bit LSB relocatable AMD64 Version 1 /etc/passwd: ascii text mixed.a: current ar archive, 32-bit symbol table mixed_elf.a: current ar archive, 32-bit symbol table not_elf.a: current ar archive same_elf.a: current ar archive, 32-bit symbol table By default, elffile uses its "summary" output style. This output differs from the output from the file utility in 2 significant ways: Files that are not an ELF object, archive, or runtime linker configuration file are identified as "non-ELF", whereas the file utility attempts further identification for such files. When applied to an archive, the elffile output includes a description of the archive's contents, without requiring member extraction or other additional steps. Applying elffile to the above files: % elffile config dwarf.o /etc/passwd mixed.a mixed_elf.a not_elf.a same_elf.a config: Runtime Linking Configuration 64-bit MSB SPARCV9 dwarf.o: ELF 64-bit LSB relocatable AMD64 Version 1 /etc/passwd: non-ELF mixed.a: current ar archive, 32-bit symbol table, mixed ELF and non-ELF content mixed_elf.a: current ar archive, 32-bit symbol table, mixed ELF content not_elf.a: current ar archive, non-ELF content same_elf.a: current ar archive, 32-bit symbol table, ELF 64-bit LSB relocatable AMD64 Version 1 The output for same_elf.a is of particular interest: The vast majority of archives contain only ELF objects for a single platform, and in this case, the default output from elffile answers both of the questions about archives posed at the beginning of this discussion, in a single efficient step. This makes elffile considerably more useful than file, within the realm of linker-related files. elffile can produce output in two other styles, "basic", and "detail". The basic style produces output that is the same as that from 'file', for linker-related files. The detail style produces per-member identification of archive contents. This can be useful when the archive contents are not homogeneous ELF object, and more information is desired than the summary output provides: % elffile -s detail mixed.a mixed.a: current ar archive, 32-bit symbol table mixed.a(dwarf.o): ELF 32-bit LSB relocatable 80386 Version 1 mixed.a(main.c): non-ELF content mixed.a(main.o): ELF 64-bit LSB relocatable AMD64 Version 1 [SSE]

  • Service injection into Controller (Spring MVC)

    - by ThaSaleni
    Hi I have a Spring web application, I have built it up to the controller stage and I could inject my Daos, into my Services fine. Now when I want to inject my Service into my controller i get an error for dependency with the Dao and further down the sessionFactory. I don't want to inject these again cause this will ultimately lead me to eventually create a data source but I have my Daos for data access and they already know about sessionFactory. Am I missing something here? here's the sample code snippets My Service: @Service("productService") @Transactional public class ProductServiceImpl implements ProductService { private ProductDao productDao; @Autowired public void setDao(ProductDao productDao) { this.productDao = productDao; } My Controller @Controller @WebServlet(name="controllerServlet", loadOnStartup= urlPatterns=...}) public class ControllerServlet extends HttpServlet { boolean isUserLogedIn =false; @Autowired private ProductService productService; public void setProductService(ProductService productService){ this.productService = productService; } Servlet-context Stack trace javax.servlet.ServletException: Servlet.init() for servlet mvcServlet threw exception org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:98) org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:927) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:999) org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java: 565) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1812) java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) java.lang.Thread.run(Thread.java:662) root cause org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'controllerServlet': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.phumzile.acme.services.ProductService com.phumzile.acme.client.web.controller.ControllerServlet.productService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.phumzile.acme.services.ProductService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

  • MS Ajax Libraries and Configured Assemblies

    - by smehaffie
    Use Case You have a brand new IIS servers that has .Net 3.5 installed and are migrating sites to the new servers.  In the process of migrating sites you come across some sites that get an error about the version of AJAX libraries being references in the web.config.  In the web.config all the entries reference 1.0.61025.0, but the older version of the AJAX libraries are not installed on the new servers, only the latest version is installed that comes with .Net 3.5.  So what are the options to fix this issue. Solutions 1) Install the older version of the AJAX Libraries: Although this works, IMO it is never a great idea to install an older version of a library after a newer version has been installed.  Plus, if all new application use the latest versions, is it worth the effort of installing the older version for a few legacy applications? 2) Update the web.config files so all references use latest version (3.5.0.0):  This option is very time consuming and error prone. In addition, you will also have to update any pages where there is a register tag for the older libraries as well.  This would require you to redeploy any application that have this issue. 3) Use the Configured Assembly capabilities of .Net (aka: Assembly Bindings) to make any application that uses the older AJAX libraries to use the new AJAX libraries.  IMO, this is the easiest, quickest and least invasive way to fix the issue.  Below are the steps to implement this fix. Solution #3 Do the following steps on the IIS servers that the issue is occurring.  The 2 assemblies that need assemblies bindings created are: System.Web.Extension & System.Web.Extensions.Design 1) Go to Start - > All Program -> Administrative Tools -> Microsoft .NET Framework 2.0 Configuration. 2) Right click on "Configured Assemblies" to view list of configured assemblies. 3) Left Click on right pane to bring up menu and choose "Add". 4) Make sure "Choose and assembly from the assembly cache is checked" and click the "Choose Assembly" button. 5) Choose System.Web.Extension (does not matter what version). 6) Click the "Finish" button. 7) Binding Policy Tab      - Enter Requested Version = 1.0.61025.0      - Enter New Version = 3.5.0.0 8) Repeat steps 2-7 for the System.Web.Extensions.Design assembly. --------------------------------------------------------------------------------------------------------------------------------------------------------- Note: If "Microsoft .NET Framework 2.0 Configuration does not exist under Admin tools use mmc to access it (see below) 1) Start -> Run -> Enter MMC 2) File - > Add/Remove Snap-In then Click "Add" button 3) Choose ".Net 2.0 Configuration" then click "Add" button and then the "Close" Button. 4) On "Add/Remove Snapin" windows click the "OK" Button. 5) Expand the tree on the right and you can start following the directions above for adding the configured assemblies. ---------------------------------------------------------------------------------------------------------------------------------------------------------

  • Migrating ASP.NET MVC 1.0 applications to ASP.NET MVC 2 RTM

    - by Eilon
    Note: ASP.NET MVC 2 RTM isn’t yet released! But this tool will help you get your ASP.NET MVC 1.0 applications ready for when it is! I have updated the MVC App Converter to convert projects from ASP.NET MVC 1.0 to ASP.NET MVC 2 RTM. This should be last the last major change to the MVC App Converter that I released previews of in the past several months. Download The app is a single executable: Download MvcAppConverter-MVC2RTM.zip (255 KB). Usage The only requirement for this tool is that you have .NET Framework 3.5 SP1 on the machine. You do not need to have Visual Studio or ASP.NET MVC installed (unless you want to open your project!). Even though the tool performs an automatic backup of your solution it is recommended that you perform a manual backup of your solution as well. To convert an ASP.NET MVC 1.0 project built with Visual Studio 2008 to an ASP.NET MVC 2 project in Visual Studio 2008 perform these steps: Launch the converter Select the solution Click the “Convert” button To convert an ASP.NET MVC 1.0 project built with Visual Studio 2008 to an ASP.NET MVC 2 project in Visual Studio 2010: Wait until Visual Studio 2010 is released (next month!) and it will have a built-in version of this tool that will run automatically when you open an ASP.NET MVC 1.0 project Perform the above steps, then open the project in Visual Studio 2010 and it will perform the remaining conversion steps What it can do Open up ASP.NET MVC 1.0 projects from Visual Studio 2008 (no other versions of ASP.NET MVC or Visual Studio are supported) Create a full backup of your solution’s folder For every VB or C# project that has a reference to System.Web.Mvc.dll it will (this includes ASP.NET MVC web application projects as well as ASP.NET MVC test projects): Update references to ASP.NET MVC 2 Add a reference to System.ComponentModel.DataAnnotations 3.5 (if not already present) For every VB or C# ASP.NET MVC Web Application it will: Change the project type to an ASP.NET MVC 2 project Update the root ~/web.config references to ASP.NET MVC 2 Update the root ~/web.config to have a binding redirect from ASP.NET MVC 1.0 to ASP.NET MVC 2 Update the ~/Views/web.config references to ASP.NET MVC 2 Add or update the JavaScript files (add jQuery, add jQuery.Validate, add Microsoft AJAX, add/update Microsoft MVC AJAX, add Microsoft MVC Validation adapter) Unknown project types or project types that have nothing to do with ASP.NET MVC will not be updated What it can’t do It cannot convert projects directly to Visual Studio 2010 or to .NET Framework 4. It can have issues if your solution contains projects that are not located under the solution directory. If you are using a source control system it might have problems overwriting files. It is recommended that before converting you check out all files from the source control system. It cannot change code in the application that might need to be changed due to breaking changes between ASP.NET MVC 1.0 and ASP.NET MVC 2. Feedback, Please! If you need to convert a project to ASP.NET MVC 2 please try out this application and hopefully you’re good to go. If you spot any bugs or features that don’t work leave a comment here and I will try to address these issues in an updated release.

  • Install Quartz.Net as a windows service and Test installation

    - by Tarun Arora
    In this blog post I’ll be covering, 01: Where to download Quartz.net from 02: How to install Quartz.net as a Windows service 03: Test the Quartz.net Installation If you are new to Quartz.net I would recommend reading the blog post on a brief introduction to Quartz.net. 01 – Where to download Quartz.net? http://sourceforge.net/projects/quartznet/files/quartznet/       Currently version  Quartz.Net 2.0.1 is the recommended download version. 02 – How to install Quartz.net as a Windows service         Go to the download location and unzip the Quartz.net package Navigate to the folder Quartz.Net \ Server \ bin – This is where you will find different .net version installers of the quartz.net packages. For example in the screen shot above, you can see the Quartz.net .net 3.5 and .net 4 packages. Open up the Quartz.net .net 4.0 folder, this folder contains the files you need to install Quartz.net as a windows service Copy the contents of the folder Downloads\Quartz.NET-2.0.1\server\bin\4.0 to the folder %program files%\Quartz.net   5. Open up a new CMD as an administrator and run the below command to install Quartz.net as a windows service /> Quartz.Server.exe install 6. How do I know that Quartz.Net service has installed as a Windows service? Go to run prompt and type ‘services.msc’ you should now see all the windows services installed on your machine. Navigate down to look for Quartz.Net. The service installs itself as an automatic startup Type and log on as ‘Local System’. You can easily change this to your prefer account that you would like to run the service as. If you wanted to name the Quartz service something else then that’s also possible… Can I change the default display name of the quartz.net windows service? Yes, you can! Navigate to C:\Program Files (x86)\Quartz.Net\ and open up the config file ‘quartz.config’ - You can change the instance name - You can change the default thread count of 10 - The port that the service listens to (by default this is port 555) A blog post on more configuration details can be found here. 03 – Test Quartz.Net windows service installation So, I have installed Quartz.Net as a windows service, how do I test whether my installation has been successful. Open up cmd as an administrator and run the below command, C:\Program Files (x86)\Quartz.Net> Quartz.Server.exe –i Since by default the Quartz.net windows service writes INFO level diagnostics (this can be changed from Quartz.Server.exe.config) you should see the service information show up on the console. For instance in the example above I can see that the service is running in a NON CLUSTERED mode, its currently not started and is currently in standby mode with 0 number of jobs executed so far… This was second in the series of posts on enterprise scheduling using Quartz.net, in the next post I’ll be covering how to run your first scheduled task using Quartz.net windows service. Thank you for taking the time out and reading this blog post. If you enjoyed the post, remember to subscribe to http://feeds.feedburner.com/TarunArora. Stay tuned!

  • Setting up SharePoint without Active Directory

    - by eJugnoo
    In order to setup SharePoint without AD, you need to run following PowerShell command on Management Shell after installing SharePoint on your server, but before running Config Wizard: (we don’t want to run this SP farm in stand-alone mode!) 1. New-SPConfigurationDatabase SYNOPSIS     Creates a new configuration database. SYNTAX     New-SPConfigurationDatabase [-DatabaseName] <String> [-DatabaseServer] <String> [[-DirectoryDomain] <String>] [[-DirectoryOrganizationUnit] <String>]     [[-AdministrationContentDatabaseName] <String>] [[-DatabaseCredentials] <PSCredential>] [-FarmCredentials] <PSCredential> [-Passphrase] <SecureString>      [-AssignmentCollection <SPAssignmentCollection>] [<CommonParameters>] DESCRIPTION     The New-SPConfigurationDatabase cmdlet creates a new configuration database on the specified database server. This is the central database for a new SharePoint farm.     For permissions and the most current information about Windows PowerShell for SharePoint Products, see the online documentation (http://go.microsoft.com/fwlink/?LinkId=163185). RELATED LINKS     Backup-SPConfigurationDatabase     Disconnect-SPConfigurationDatabase     Connect-SPConfigurationDatabase     Remove-SPConfigurationDatabase REMARKS     To see the examples, type: "get-help New-SPConfigurationDatabase -examples".     For more information, type: "get-help New-SPConfigurationDatabase -detailed".     For technical information, type: "get-help New-SPConfigurationDatabase -full". NOTE: Use –AdministrationContentDatabaseName switch to pass the name of Admin database you want instead of GUID-based name it automatically creates. Hence, one can pretty much easily control Admin, Config, and Content database names at the time of farm creation. If creating new farm, you can also delete and re-provision any service databases automatically created, from UI, to decide what database names you want. 2. Run SharePoint Configuration Wizard, and you’ll following as already added to farm. Select do not discconect from farm, and proceed… Select the port, and authentication (NTLM in my case). Click next, and wizard will complete the remaining steps of provisioning, including creation of Central Admin Web App on the desired port. Once successful, it will open the Central Admin site and ask you to run Farm Config Wizard. I chose to skip and do things manually, to remain in control of what is happening on the farm. Like creating web-app for site collections, creating the very first site collection, and any other service applications. I needed this to create a public-facing installation of SharePoint Foundation RTM on a server which didn’t have AD. Now I am going to setup FBA, and possibly Live ID Auth as well. I will be also setting up RBS, and multi-tenancy on this farm ,and would post any notes, and findings here… --Sharad

  • Use Any Folder For Your Ubuntu Desktop (Even a Dropbox Folder)

    - by Trevor Bekolay
    By default, Ubuntu creates a folder called Desktop in your home directory that gets displayed on your desktop. What if you want to use something else, like your Dropbox folder? Here we look at how to use any folder for your desktop. Not only can you change your desktop folder, you can change the location of any other folder Ubuntu creates for you in your home folder, like Documents or Music – and this works in any Linux distribution using the Gnome desktop manager. In this example, we’re going to change desktop to show our Dropbox folder. Open your home folder in a File Browser by clicking on Places > Home Folder. In the Home Folder, open the .config folder. By default, .config is hidden, so you may have to show hidden folders (temporarily) by clicking on View > Show Hidden Files. Then open the .config folder by double-clicking on it. Now open the user-dirs.dirs file… If double-clicking on it does not open it in a text editor, right-click on it and choose Open with Other Application… and find a text editor like Gedit. Change the entry associated with XDG_DESKTOP_DIR to the folder you want to be shown as your desktop. In our case, this is $HOME/Dropbox. Note: The “~” shortcut for the home directory won’t work in this file (use $HOME for that), but an absolute path (i.e. a path starting with “/”) will work. Feel free to change the locations of the other folders as well. Save and close user-dirs.dirs. At this point you can either log off and then log back on to get your desktop back, or open a terminal window Applications > Accessories > Terminal and enter: killall nautilus Nautilus (the file manager in Gnome) will restart itself and display your newly chosen folder as the desktop! This is a cool trick to use any folder for your Ubuntu desktop. What did you use as your desktop folder? Let us know in the comments!

  • Bash completion doesn't work, or is ignoring what I've typed; but works for commands

    - by Neil Traft
    Bash completion seems to be ignoring what I've typed (it tries to complete, but acts as if there's nothing under the cursor). I know I saw it work on this machine earlier today, but I'm not sure what has changed.

  • Ubuntu 12.04 lightdm dumps to tty. Cannot start GUI interface when booting off harddrive, but can when booting off usb

    - by user72681
    When booting, lightdm dumps to tty. No GUI interface works- this is after a fresh install of Ubuntu 12.04 where the GUI interface works when running off the USB.

  • Adding Output Caching and Expire Header in IIS7 to improve performance

    - by Renso
    The problem: Images and other static files will not be cached unless you tell it to. In IIS7 it is remarkably easy to do this. Web pages are becoming increasingly complex with more scripts, style sheets, images, and Flash on them. A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts, style sheets, and Flash. Every time a page is loaded, every image and other static content like JavaScript files and CSS files will be reloaded on every page request. If the content does not change frequently why not cache it and avoid the network traffic?! The solution: In IIS7 there are two ways to cache content, using the web.config file to set caching for all static content, and in IIS7 itself setting aching by file extension that gives you that extra level of granularity. Web.config: In IIS7, Expires Headers can be enabled in the system.webServer section of the web.config file:   <staticContent>     <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />   </staticContent> In the above example a cache expiration of 1 day was added. It will be a full day before the content is downloaded from the web server again. To expire the content on a specific date:   <staticContent>     <clientCache cacheControlMode="UseExpires" httpExpires="Sun, 31 Dec 2011 23:59:59 UTC" />   </staticContent> This will expire the content on December 31st 2011 one second before midnight. Issues/Challenges: Once the file has been set to be cached it wont be updated on the user's browser for the set cache expiration. So be careful here with content that may change frequently, like during development. Typically in development you don't want to cache at all for testing purposes. You could also suffix files with timestamp or versions to force a reload into the user's browser cache. IIS7 Expire Web Content Open up your web app in IIS. Open up the sub-folders until you find the folder or file you want to ad an expiration date to. In IIS6 you used to right-click and select properties, no such luck in IIS7, double click HTTP Response. Once the window loads for the HTTP Response Headers, look to the Actions navigation bar to the right, all the way at the top select SET COMMON HEADERS. The Enable HTTP keep-alive will already be pre-selected. Go ahead and add the appropriate expiration header to the file or folder. Note that if you selected a folder, it will apply that setting to all images inside that folder and all nested content, even subfolders. So, two approaches, depending on what level or granularity you need.

  • Setup and configure a MVC4 project for Cloud Service(web role) and SQL Azure

    - by MagnusKarlsson
    I aim at keeping this blog post updated and add related posts to it. Since there are a lot of these out there I link to others that has done kind of the same before me, kind of a blog-DRY pattern that I'm aiming for. I also keep all mistakes and misconceptions for others to see. As an example; if I hit a stacktrace I will google it if I don't directly figure out the reason for it. I will then probably take the most plausible result and try it out. If it fails because I misinterpreted the error I will not delete it from the log but keep it for future reference and for others to see. That way people that finds this blog can see multiple solutions for indexed stacktraces and I can better remember how to do stuff. To avoid my errors I recommend you to read through it all before going from start to finish.The steps:Setup project in VS2012. (msdn blog)Setup Azure Services (half of mpspartners.com blog)Setup connections strings and configuration files (msdn blog + notes)Export certificates.Create Azure package from vs2012 and deploy to staging (same steps as for production).Connections string error Set up the visual studio project:http://blogs.msdn.com/b/avkashchauhan/archive/2011/11/08/developing-asp-net-mvc4-based-windows-azure-web-role.aspx Then login in to Azure to setup the services:Stop following this guide at the "publish website" part since we'll be uploading a package.http://www.mpspartners.com/2012/09/ConfiguringandDeployinganMVC4applicationasaCloudServicewithAzureSQLandStorage/ When set up (connection strings for debug and release and all), follow this guide to set up the configuration files:http://msdn.microsoft.com/en-us/library/windowsazure/hh369931.aspxTrying to package our application at this step will generate the following warning:3>MvcWebRole1(0,0): warning WAT170: The configuration setting 'Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString' is set up to use the local storage emulator for role 'MvcWebRole1' in configuration file 'ServiceConfiguration.Cloud.cscfg'. To access Windows Azure storage services, you must provide a valid Windows Azure storage connection string. Right click the web role under roles in solution manager and choose properties. Choose "Service configuration: Cloud". At "specify storage account credentials" we will copy/paste our account name and key from the Azure management platform.3.1 4. Right click Remote desktop Configuration and select certificate and export to file. We need to allow it in Portal manager.4.15 Now right click the cloud project and select package.5.1 Showing dialogue box. 5.2 Package success Now copy the path to the packaged file and go to management portal again. Click your web role and choose staging (or production). Upload. 5.3Tick the box about the single instance if that's what you want or you don't know what it means. Otherwise the following will happen (see image 4.6)5.4 Dialogue box When you have clicked the symbol for accept- button you will see the following screen with some green indicators down at the right corner. Click them if you want to see status.5.5 Information screen.5.6 "Failed to deploy application. The upload application has at least one role with only one instance. We recommend that you deploy at least two instances per role to ensure high availability in case one of the instances becomes unavailable. "To fix, go to step 5.4If you forgot to (or just didn't know you were supposed to) export your certificates. The following error will occur. Side note, the following thread suggests. To prevent: "Enable Remote Desktop for all roles" when right-clicking BIAB and choosing "Package". But in my case it was the not so present certificates.

  • Try the Oracle Database Appliance Manager Configurator - For Fun!

    - by pwstephe-Oracle
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 If you would like to get a first hand glimpse of how easy it is to configure an ODA, even if you don’t have access to one, it’s possible to download the Appliance Manager Configurator from the Oracle Technology Network, and run it standalone on your PC or Linux/Unix  workstation. The configurator is packaged in a zip file that contains the complete Java environment to run standalone. Once the package is downloaded and unzipped it’s simply a matter of launching it using the config command or shell depending on your runtime environment. Oracle Appliance Manager Configurator is a Java-based tool that enables you to input your deployment plan and validate your network settings before an actual deployment, or you can just preview and experiment with it. Simply download and run the configurator on a local client system which can be a Windows, Linux, or UNIX system. (For Windows launch the batch file config.bat for Linux/Unix environments, run  ./ config.sh). You will be presented with the very same dialogs and options used to configure a production ODA but on your workstation. At the end of a configurator session, you may save your deployment plan in a configuration file. If you were actually ready to deploy, you could copy this configuration file to a real ODA where the online Oracle Appliance Manager Configurator would use the contents to deploy your plan in production. You may also print the file’s content and use the printout as a checklist for setting up your production external network configuration. Be sure to use the actual production network addresses you intend to use it as this will only work correctly if your client system is connected to same network that will be used for the ODA. (This step is not necessary if you are just previewing the Configurator). This is a great way to get an introductory look at the simple and intuitive Database Appliance configuration interface and the steps to configure a system. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    - by subw
    I'm trying to create an installer using Apple's PackageMaker.app. As part of the installation, I want to install SIMBL with the metapackage mechanism provided by PackageMaker. However, when I add the SIMBL .pkg file and try to build my own package, I get the warning "No payload could be found. The package will not be built." for the SIMBL package reference. The same worked for an older version of SIMBL (0.8.*).
