• 12.04: Apt-Get Update: failure to fetch; can't connect to any sources

  - by weberc2

  I realize there are dozens of "apt-get update: failure to fetch" questions (I read through all I could find), but my present circumstance is unique to 12.04 and it affects all sources; not just launchpad. Additionally, I've tried several different servers in Europe and the U.S. as well as the "main server" (wherever that is) and they all yield the same result: I can't connect to any software sources. Additionally, I'm fairly certain the problem stems from the upgrade from 11.10-12.04 I performed this morning, as updates worked immediately before. Updates from the Update Manager worked fine and I could download some things (mutter) from the Software Center without incident, which makes me think I can connect to some subset of the Ubuntu servers (however, several other Ubuntu servers--like extras--and some canonical servers are listed as 'unable to connect'). Here is the output from sudo apt-get update: sudo apt-get update Ign http://ftp.u-picardie.fr precise InRelease Ign http://archive.canonical.com precise InRelease Ign http://ftp.u-picardie.fr precise-updates InRelease Ign http://ftp.u-picardie.fr precise-backports InRelease Err http://ftp.u-picardie.fr precise-security InRelease Err http://ftp.u-picardie.fr precise Release.gpg Unable to connect to ftp.u-picardie.fr:http: Err http://ftp.u-picardie.fr precise-updates Release.gpg Unable to connect to ftp.u-picardie.fr:http: Err http://ftp.u-picardie.fr precise-backports Release.gpg Unable to connect to ftp.u-picardie.fr:http: Err http://ftp.u-picardie.fr precise-security Release.gpg Unable to connect to ftp.u-picardie.fr:http: Hit http://archive.canonical.com precise Release.gpg Hit http://archive.canonical.com precise Release Hit http://archive.canonical.com precise/partner i386 Packages Ign http://archive.canonical.com precise/partner TranslationIndex Ign http://dl.google.com stable InRelease Ign http://dl.google.com stable InRelease Err http://archive.canonical.com precise/partner Translation-en_US Unable to connect to archive.canonical.com:http: [IP: 91.189.92.150 80] Err http://archive.canonical.com precise/partner Translation-en Unable to connect to archive.canonical.com:http: [IP: 91.189.92.150 80] Ign http://extras.ubuntu.com precise InRelease Get:1 http://dl.google.com stable Release.gpg [198 B] Err http://extras.ubuntu.com precise Release.gpg Could not connect to extras.ubuntu.com:80 (91.189.88.33). - connect (111: Connection refused) Ign http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Err http://ppa.launchpad.net precise InRelease Get:2 http://dl.google.com stable Release.gpg [198 B] Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Err http://ppa.launchpad.net precise Release.gpg Unable to connect to ppa.launchpad.net:http: Get:3 http://dl.google.com stable Release [1,347 B] Get:4 http://dl.google.com stable Release [1,347 B] Get:5 http://dl.google.com stable/main i386 Packages [1,268 B] Ign http://dl.google.com stable/main TranslationIndex Get:6 http://dl.google.com stable/main i386 Packages [769 B] Ign http://dl.google.com stable/main TranslationIndex Ign http://dl.google.com stable/main Translation-en_US Ign http://dl.google.com stable/main Translation-en Ign http://dl.google.com stable/main Translation-en_US Ign http://dl.google.com stable/main Translation-en Fetched 5,127 B in 7s (673 B/s) Reading package lists...

• IBM Websphere on Windows- OutOfMemoryError: Failed to create a thread

  - by Kishnan

  I have a J2EE application running on an IBM Websphere Application Server on a Windows Operating System. Occasionally I see an OutOfMemoryError Exception with the following information in the javacore file. 1TISIGINFO Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError":"Failed to create a thread: retVal -1073741830, errno 12" received Java is run with the following configurations: -Xms512m -Xmx1350m -Xscmx50M Analyzing the javacore file, the number of threads are just 124. Analyzing the heap dump, the memory occupied by the heap is about 500Mb. Given the relatively normal number of threads and heap size a lot lower than the maximum, I am trying to figure out why I see this error?

• Use IIS Application Initialization for keeping ASP.NET Apps alive

  - by Rick Strahl

  I've been working quite a bit with Windows Services in the recent months, and well, it turns out that Windows Services are quite a bear to debug, deploy, update and maintain. The process of getting services set up,  debugged and updated is a major chore that has to be extensively documented and or automated specifically. On most projects when a service is built, people end up scrambling for the right 'process' to use for administration. Web app deployment and maintenance on the other hand are common and well understood today, as we are constantly dealing with Web apps. There's plenty of infrastructure and tooling built into Web Tools like Visual Studio to facilitate the process. By comparison Windows Services or anything self-hosted for that matter seems convoluted.In fact, in a recent blog post I mentioned that on a recent project I'd been using self-hosting for SignalR inside of a Windows service, because the application is in fact a 'service' that also needs to send out lots of messages via SignalR. But the reality is that it could just as well be an IIS application with a service component that runs in the background. Either way you look at it, it's either a Windows Service with a built in Web Server, or an IIS application running a Service application, neither of which follows the standard Service or Web App template.Personally I much prefer Web applications. Running inside of IIS I get all the benefits of the IIS platform including service lifetime management (crash and restart), controlled shutdowns, the whole security infrastructure including easy certificate support, hot-swapping of code and the the ability to publish directly to IIS from within Visual Studio with ease.Because of these benefits we set out to move from the self hosted service into an ASP.NET Web app instead.The Missing Link for ASP.NET as a Service: Auto-LoadingI've had moments in the past where I wanted to run a 'service like' application in ASP.NET because when you think about it, it's so much easier to control a Web application remotely. Services are locked into start/stop operations, but if you host inside of a Web app you can write your own ticket and control it from anywhere. In fact nearly 10 years ago I built a background scheduling application that ran inside of ASP.NET and it worked great and it's still running doing its job today.The tricky part for running an app as a service inside of IIS then and now, is how to get IIS and ASP.NET launched so your 'service' stays alive even after an Application Pool reset. 7 years ago I faked it by using a web monitor (my own West Wind Web Monitor app) I was running anyway to monitor my various web sites for uptime, and having the monitor ping my 'service' every 20 seconds to effectively keep ASP.NET alive or fire it back up after a reload. I used a simple scheduler class that also includes some logic for 'self-reloading'. Hacky for sure, but it worked reliably.Luckily today it's much easier and more integrated to get IIS to launch ASP.NET as soon as an Application Pool is started by using the Application Initialization Module. The Application Initialization Module basically allows you to turn on Preloading on the Application Pool and the Site/IIS App, which essentially fires a request through the IIS pipeline as soon as the Application Pool has been launched. This means that effectively your ASP.NET app becomes active immediately, Application_Start is fired making sure your app stays up and running at all times. All the other features like Application Pool recycling and auto-shutdown after idle time still work, but IIS will then always immediately re-launch the application.Getting started with Application InitializationAs of IIS 8 Application Initialization is part of the IIS feature set. For IIS 7 and 7.5 there's a separate download available via Web Platform Installer. Using IIS 8 Application Initialization is an optional install component in Windows or the Windows Server Role Manager: This is an optional component so make sure you explicitly select it.IIS Configuration for Application InitializationInitialization needs to be applied on the Application Pool as well as the IIS Application level. As of IIS 8 these settings can be made through the IIS Administration console.Start with the Application Pool:Here you need to set both the Start Automatically which is always set, and the StartMode which should be set to AlwaysRunning. Both have to be set - the Start Automatically flag is set true by default and controls the starting of the application pool itself while Always Running flag is required in order to launch the application. Without the latter flag set the site settings have no effect.Now on the Site/Application level you can specify whether the site should pre load: Set the Preload Enabled flag to true.At this point ASP.NET apps should auto-load. This is all that's needed to pre-load the site if all you want is to get your site launched automatically.If you want a little more control over the load process you can add a few more settings to your web.config file that allow you to show a static page while the App is starting up. This can be useful if startup is really slow, so rather than displaying blank screen while the user is fiddling their thumbs you can display a static HTML page instead: <system.webServer> <applicationInitialization remapManagedRequestsTo="Startup.htm" skipManagedModules="true"> <add initializationPage="ping.ashx" /> </applicationInitialization> </system.webServer>This allows you to specify a page to execute in a dry run. IIS basically fakes request and pushes it directly into the IIS pipeline without hitting the network. You specify a page and IIS will fake a request to that page in this case ping.ashx which just returns a simple OK string - ie. a fast pipeline request. This request is run immediately after Application Pool restart, and while this request is running and your app is warming up, IIS can display an alternate static page - Startup.htm above. So instead of showing users an empty loading page when clicking a link on your site you can optionally show some sort of static status page that says, "we'll be right back".  I'm not sure if that's such a brilliant idea since this can be pretty disruptive in some cases. Personally I think I prefer letting people wait, but at least get the response they were supposed to get back rather than a random page. But it's there if you need it.Note that the web.config stuff is optional. If you don't provide it IIS hits the default site link (/) and even if there's no matching request at the end of that request it'll still fire the request through the IIS pipeline. Ideally though you want to make sure that an ASP.NET endpoint is hit either with your default page, or by specify the initializationPage to ensure ASP.NET actually gets hit since it's possible for IIS fire unmanaged requests only for static pages (depending how your pipeline is configured).What about AppDomain Restarts?In addition to full Worker Process recycles at the IIS level, ASP.NET also has to deal with AppDomain shutdowns which can occur for a variety of reasons:Files are updated in the BIN folderWeb Deploy to your siteweb.config is changedHard application crashThese operations don't cause the worker process to restart, but they do cause ASP.NET to unload the current AppDomain and start up a new one. Because the features above only apply to Application Pool restarts, AppDomain restarts could also cause your 'ASP.NET service' to stop processing in the background.In order to keep the app running on AppDomain recycles, you can resort to a simple ping in the Application_End event:protected void Application_End() { var client = new WebClient(); var url = App.AdminConfiguration.MonitorHostUrl + "ping.aspx"; client.DownloadString(url); Trace.WriteLine("Application Shut Down Ping: " + url); }which fires any ASP.NET url to the current site at the very end of the pipeline shutdown which in turn ensures that the site immediately starts back up.Manual Configuration in ApplicationHost.configThe above UI corresponds to the following ApplicationHost.config settings. If you're using IIS 7, there's no UI for these flags so you'll have to manually edit them.When you install the Application Initialization component into IIS it should auto-configure the module into ApplicationHost.config. Unfortunately for me, with Mr. Murphy in his best form for me, the module registration did not occur and I had to manually add it.<globalModules> <add name="ApplicationInitializationModule" image="%windir%\System32\inetsrv\warmup.dll" /> </globalModules>Most likely you won't need ever need to add this, but if things are not working it's worth to check if the module is actually registered.Next you need to configure the ApplicationPool and the Web site. The following are the two relevant entries in ApplicationHost.config.<system.applicationHost> <applicationPools> <add name="West Wind West Wind Web Connection" autoStart="true" startMode="AlwaysRunning" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated"> <processModel identityType="LocalSystem" setProfileEnvironment="true" /> </add> </applicationPools> <sites> <site name="Default Web Site" id="1"> <application path="/MPress.Workflow.WebQueueMessageManager" applicationPool="West Wind West Wind Web Connection" preloadEnabled="true"> <virtualDirectory path="/" physicalPath="C:\Clients\…" /> </application> </site> </sites> </system.applicationHost>On the Application Pool make sure to set the autoStart and startMode flags to true and AlwaysRunning respectively. On the site make sure to set the preloadEnabled flag to true.And that's all you should need. You can still set the web.config settings described above as well.ASP.NET as a Service?In the particular application I'm working on currently, we have a queue manager that runs as standalone service that polls a database queue and picks out jobs and processes them on several threads. The service can spin up any number of threads and keep these threads alive in the background while IIS is running doing its own thing. These threads are newly created threads, so they sit completely outside of the IIS thread pool. In order for this service to work all it needs is a long running reference that keeps it alive for the life time of the application.In this particular app there are two components that run in the background on their own threads: A scheduler that runs various scheduled tasks and handles things like picking up emails to send out outside of IIS's scope and the QueueManager. Here's what this looks like in global.asax:public class Global : System.Web.HttpApplication { private static ApplicationScheduler scheduler; private static ServiceLauncher launcher; protected void Application_Start(object sender, EventArgs e) { // Pings the service and ensures it stays alive scheduler = new ApplicationScheduler() { CheckFrequency = 600000 }; scheduler.Start(); launcher = new ServiceLauncher(); launcher.Start(); // register so shutdown is controlled HostingEnvironment.RegisterObject(launcher); }}By keeping these objects around as static instances that are set only once on startup, they survive the lifetime of the application. The code in these classes is essentially unchanged from the Windows Service code except that I could remove the various overrides required for the Windows Service interface (OnStart,OnStop,OnResume etc.). Otherwise the behavior and operation is very similar.In this application ASP.NET serves two purposes: It acts as the host for SignalR and provides the administration interface which allows remote management of the 'service'. I can start and stop the service remotely by shutting down the ApplicationScheduler very easily. I can also very easily feed stats from the queue out directly via a couple of Web requests or (as we do now) through the SignalR service.Registering a Background Object with ASP.NETNotice also the use of the HostingEnvironment.RegisterObject(). This function registers an object with ASP.NET to let it know that it's a background task that should be notified if the AppDomain shuts down. RegisterObject() requires an interface with a Stop() method that's fired and allows your code to respond to a shutdown request. Here's what the IRegisteredObject::Stop() method looks like on the launcher:public void Stop(bool immediate = false) { LogManager.Current.LogInfo("QueueManager Controller Stopped."); Controller.StopProcessing(); Controller.Dispose(); Thread.Sleep(1500); // give background threads some time HostingEnvironment.UnregisterObject(this); }Implementing IRegisterObject should help with reliability on AppDomain shutdowns. Thanks to Justin Van Patten for pointing this out to me on Twitter.RegisterObject() is not required but I would highly recommend implementing it on whatever object controls your background processing to all clean shutdowns when the AppDomain shuts down.Testing it outI'm still in the testing phase with this particular service to see if there are any side effects. But so far it doesn't look like it. With about 50 lines of code I was able to replace the Windows service startup to Web start up - everything else just worked as is. An honorable mention goes to SignalR 2.0's oWin hosting, because with the new oWin based hosting no code changes at all were required, merely a couple of configuration file settings and an assembly directive needed, to point at the SignalR startup class. Sweet!It also seems like SignalR is noticeably faster running inside of IIS compared to self-host. Startup feels faster because of the preload.Starting and Stopping the 'Service'Because the application is running as a Web Server, it's easy to have a Web interface for starting and stopping the services running inside of the service. For our queue manager the SignalR service and front monitoring app has a play and stop button for toggling the queue.If you want more administrative control and have it work more like a Windows Service you can also stop the application pool explicitly from the command line which would be equivalent to stopping and restarting a service.To start and stop from the command line you can use the IIS appCmd tool. To stop:> %windir%\system32\inetsrv\appcmd stop apppool /apppool.name:"Weblog"and to start> %windir%\system32\inetsrv\appcmd start apppool /apppool.name:"Weblog"Note that when you explicitly force the AppPool to stop running either in the UI (on the ApplicationPools page use Start/Stop) or via command line tools, the application pool will not auto-restart immediately. You have to manually start it back up.What's not to like?There are certainly a lot of benefits to running a background service in IIS, but… ASP.NET applications do have more overhead in terms of memory footprint and startup time is a little slower, but generally for server applications this is not a big deal. If the application is stable the service should fire up and stay running indefinitely. A lot of times this kind of service interface can simply be attached to an existing Web application, or if scalability requires be offloaded to its own Web server.Easier to work withBut the ultimate benefit here is that it's much easier to work with a Web app as opposed to a service. While developing I can simply turn off the auto-launch features and launch the service on demand through IIS simply by hitting a page on the site. If I want to shut down an IISRESET -stop will shut down the service easily enough. I can then attach a debugger anywhere I want and this works like any other ASP.NET application. Yes you end up on a background thread for debugging but Visual Studio handles that just fine and if you stay on a single thread this is no different than debugging any other code.SummaryUsing ASP.NET to run background service operations is probably not a super common scenario, but it probably should be something that is considered carefully when building services. Many applications have service like features and with the auto-start functionality of the Application Initialization module, it's easy to build this functionality into ASP.NET. Especially when combined with the notification features of SignalR it becomes very, very easy to create rich services that can also communicate their status easily to the outside world.Whether it's existing applications that need some background processing for scheduling related tasks, or whether you just create a separate site altogether just to host your service it's easy to do and you can leverage the same tool chain you're already using for other Web projects. If you have lots of service projects it's worth considering… give it some thought…© Rick Strahl, West Wind Technologies, 2005-2013Posted in ASP.NET  SignalR  IIS   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Announcing the Release of Visual Studio 2013 and Great Improvements to ASP.NET and Entity Framework

  - by ScottGu

  Today we released VS 2013 and .NET 4.5.1. These releases include a ton of great improvements, and include some fantastic enhancements to ASP.NET and the Entity Framework.  You can download and start using them now. Below are details on a few of the great ASP.NET, Web Development, and Entity Framework improvements you can take advantage of with this release.  Please visit http://www.asp.net/vnext for additional release notes, documentation, and tutorials. One ASP.NET With the release of Visual Studio 2013, we have taken a step towards unifying the experience of using the different ASP.NET sub-frameworks (Web Forms, MVC, Web API, SignalR, etc), and you can now easily mix and match the different ASP.NET technologies you want to use within a single application. When you do a File-New Project with VS 2013 you’ll now see a single ASP.NET Project option: Selecting this project will bring up an additional dialog that allows you to start with a base project template, and then optionally add/remove the technologies you want to use in it.  For example, you could start with a Web Forms template and add Web API or Web Forms support for it, or create a MVC project and also enable Web Forms pages within it: This makes it easy for you to use any ASP.NET technology you want within your apps, and take advantage of any feature across the entire ASP.NET technology span. Richer Authentication Support The new “One ASP.NET” project dialog also includes a new Change Authentication button that, when pushed, enables you to easily change the authentication approach used by your applications – and makes it much easier to build secure applications that enable SSO from a variety of identity providers.  For example, when you start with the ASP.NET Web Forms or MVC templates you can easily add any of the following authentication options to the application: No Authentication Individual User Accounts (Single Sign-On support with FaceBook, Twitter, Google, and Microsoft ID – or Forms Auth with ASP.NET Membership) Organizational Accounts (Single Sign-On support with Windows Azure Active Directory ) Windows Authentication (Active Directory in an intranet application) The Windows Azure Active Directory support is particularly cool.  Last month we updated Windows Azure Active Directory so that developers can now easily create any number of Directories using it (for free and deployed within seconds).  It now takes only a few moments to enable single-sign-on support within your ASP.NET applications against these Windows Azure Active Directories.  Simply choose the “Organizational Accounts” radio button within the Change Authentication dialog and enter the name of your Windows Azure Active Directory to do this: This will automatically configure your ASP.NET application to use Windows Azure Active Directory and register the application with it.  Now when you run the app your users can easily and securely sign-in using their Active Directory credentials within it – regardless of where the application is hosted on the Internet. For more information about the new process for creating web projects, see Creating ASP.NET Web Projects in Visual Studio 2013. Responsive Project Templates with Bootstrap The new default project templates for ASP.NET Web Forms, MVC, Web API and SPA are built using Bootstrap. Bootstrap is an open source CSS framework that helps you build responsive websites which look great on different form factors such as mobile phones, tables and desktops. For example in a browser window the home page created by the MVC template looks like the following: When you resize the browser to a narrow window to see how it would like on a phone, you can notice how the contents gracefully wrap around and the horizontal top menu turns into an icon: When you click the menu-icon above it expands into a vertical menu – which enables a good navigation experience for small screen real-estate devices: We think Bootstrap will enable developers to build web applications that work even better on phones, tablets and other mobile devices – and enable you to easily build applications that can leverage the rich ecosystem of Bootstrap CSS templates already out there.  You can learn more about Bootstrap here. Visual Studio Web Tooling Improvements Visual Studio 2013 includes a new, much richer, HTML editor for Razor files and HTML files in web applications. The new HTML editor provides a single unified schema based on HTML5. It has automatic brace completion, jQuery UI and AngularJS attribute IntelliSense, attribute IntelliSense Grouping, and other great improvements. For example, typing “ng-“ on an HTML element will show the intellisense for AngularJS: This support for AngularJS, Knockout.js, Handlebars and other SPA technologies in this release of ASP.NET and VS 2013 makes it even easier to build rich client web applications: The screen shot below demonstrates how the HTML editor can also now inspect your page at design-time to determine all of the CSS classes that are available. In this case, the auto-completion list contains classes from Bootstrap’s CSS file. No more guessing at which Bootstrap element names you need to use: Visual Studio 2013 also comes with built-in support for both CoffeeScript and LESS editing support. The LESS editor comes with all the cool features from the CSS editor and has specific Intellisense for variables and mixins across all the LESS documents in the @import chain. Browser Link – SignalR channel between browser and Visual Studio The new Browser Link feature in VS 2013 lets you run your app within multiple browsers on your dev machine, connect them to Visual Studio, and simultaneously refresh all of them just by clicking a button in the toolbar. You can connect multiple browsers (including IE, FireFox, Chrome) to your development site, including mobile emulators, and click refresh to refresh all the browsers all at the same time.  This makes it much easier to easily develop/test against multiple browsers in parallel. Browser Link also exposes an API to enable developers to write Browser Link extensions.  By enabling developers to take advantage of the Browser Link API, it becomes possible to create very advanced scenarios that crosses boundaries between Visual Studio and any browser that’s connected to it. Web Essentials takes advantage of the API to create an integrated experience between Visual Studio and the browser’s developer tools, remote controlling mobile emulators and a lot more. You will see us take advantage of this support even more to enable really cool scenarios going forward. ASP.NET Scaffolding ASP.NET Scaffolding is a new code generation framework for ASP.NET Web applications. It makes it easy to add boilerplate code to your project that interacts with a data model. In previous versions of Visual Studio, scaffolding was limited to ASP.NET MVC projects. With Visual Studio 2013, you can now use scaffolding for any ASP.NET project, including Web Forms. When using scaffolding, we ensure that all required dependencies are automatically installed for you in the project. For example, if you start with an ASP.NET Web Forms project and then use scaffolding to add a Web API Controller, the required NuGet packages and references to enable Web API are added to your project automatically.  To do this, just choose the Add->New Scaffold Item context menu: Support for scaffolding async controllers uses the new async features from Entity Framework 6. ASP.NET Identity ASP.NET Identity is a new membership system for ASP.NET applications that we are introducing with this release. ASP.NET Identity makes it easy to integrate user-specific profile data with application data. ASP.NET Identity also allows you to choose the persistence model for user profiles in your application. You can store the data in a SQL Server database or another data store, including NoSQL data stores such as Windows Azure Storage Tables. ASP.NET Identity also supports Claims-based authentication, where the user’s identity is represented as a set of claims from a trusted issuer. Users can login by creating an account on the website using username and password, or they can login using social identity providers (such as Microsoft Account, Twitter, Facebook, Google) or using organizational accounts through Windows Azure Active Directory or Active Directory Federation Services (ADFS). To learn more about how to use ASP.NET Identity visit http://www.asp.net/identity.  ASP.NET Web API 2 ASP.NET Web API 2 has a bunch of great improvements including: Attribute routing ASP.NET Web API now supports attribute routing, thanks to a contribution by Tim McCall, the author of http://attributerouting.net. With attribute routing you can specify your Web API routes by annotating your actions and controllers like this: OAuth 2.0 support The Web API and Single Page Application project templates now support authorization using OAuth 2.0. OAuth 2.0 is a framework for authorizing client access to protected resources. It works for a variety of clients including browsers and mobile devices. OData Improvements ASP.NET Web API also now provides support for OData endpoints and enables support for both ATOM and JSON-light formats. With OData you get support for rich query semantics, paging, $metadata, CRUD operations, and custom actions over any data source. Below are some of the specific enhancements in ASP.NET Web API 2 OData. Support for $select, $expand, $batch, and $value Improved extensibility Type-less support Reuse an existing model OWIN Integration ASP.NET Web API now fully supports OWIN and can be run on any OWIN capable host. With OWIN integration, you can self-host Web API in your own process alongside other OWIN middleware, such as SignalR. For more information, see Use OWIN to Self-Host ASP.NET Web API. More Web API Improvements In addition to the features above there have been a host of other features in ASP.NET Web API, including CORS support Authentication Filters Filter Overrides Improved Unit Testability Portable ASP.NET Web API Client To learn more go to http://www.asp.net/web-api/ ASP.NET SignalR 2 ASP.NET SignalR is library for ASP.NET developers that dramatically simplifies the process of adding real-time web functionality to your applications. Real-time web functionality is the ability to have server-side code push content to connected clients instantly as it becomes available. SignalR 2.0 introduces a ton of great improvements. We’ve added support for Cross-Origin Resource Sharing (CORS) to SignalR 2.0. iOS and Android support for SignalR have also been added using the MonoTouch and MonoDroid components from the Xamarin library (for more information on how to use these additions, see the article Using Xamarin Components from the SignalR wiki). We’ve also added support for the Portable .NET Client in SignalR 2.0 and created a new self-hosting package. This change makes the setup process for SignalR much more consistent between web-hosted and self-hosted SignalR applications. To learn more go to http://www.asp.net/signalr. ASP.NET MVC 5 The ASP.NET MVC project templates integrate seamlessly with the new One ASP.NET experience and enable you to integrate all of the above ASP.NET Web API, SignalR and Identity improvements. You can also customize your MVC project and configure authentication using the One ASP.NET project creation wizard. The MVC templates have also been updated to use ASP.NET Identity and Bootstrap as well. An introductory tutorial to ASP.NET MVC 5 can be found at Getting Started with ASP.NET MVC 5. This release of ASP.NET MVC also supports several nice new MVC-specific features including: Authentication filters: These filters allow you to specify authentication logic per-action, per-controller or globally for all controllers. Attribute Routing: Attribute Routing allows you to define your routes on actions or controllers. To learn more go to http://www.asp.net/mvc Entity Framework 6 Improvements Visual Studio 2013 ships with Entity Framework 6, which bring a lot of great new features to the data access space: Async and Task<T> Support EF6’s new Async Query and Save support enables you to perform asynchronous data access and take advantage of the Task<T> support introduced in .NET 4.5 within data access scenarios.  This allows you to free up threads that might otherwise by blocked on data access requests, and enable them to be used to process other requests whilst you wait for the database engine to process operations. When the database server responds the thread will be re-queued within your ASP.NET application and execution will continue.  This enables you to easily write significantly more scalable server code. Here is an example ASP.NET WebAPI action that makes use of the new EF6 async query methods: Interception and Logging Interception and SQL logging allows you to view – or even change – every command that is sent to the database by Entity Framework. This includes a simple, human readable log – which is great for debugging – as well as some lower level building blocks that give you access to the command and results. Here is an example of wiring up the simple log to Debug in the constructor of an MVC controller: Custom Code-First Conventions The new Custom Code-First Conventions enable bulk configuration of a Code First model – reducing the amount of code you need to write and maintain. Conventions are great when your domain classes don’t match the Code First conventions. For example, the following convention configures all properties that are called ‘Key’ to be the primary key of the entity they belong to. This is different than the default Code First convention that expects Id or <type name>Id. Connection Resiliency The new Connection Resiliency feature in EF6 enables you to register an execution strategy to handle – and potentially retry – failed database operations. This is especially useful when deploying to cloud environments where dropped connections become more common as you traverse load balancers and distributed networks. EF6 includes a built-in execution strategy for SQL Azure that knows about retryable exception types and has some sensible – but overridable – defaults for the number of retries and time between retries when errors occur. Registering it is simple using the new Code-Based Configuration support: These are just some of the new features in EF6. You can visit the release notes section of the Entity Framework site for a complete list of new features. Microsoft OWIN Components Open Web Interface for .NET (OWIN) defines an open abstraction between .NET web servers and web applications, and the ASP.NET “Katana” project brings this abstraction to ASP.NET. OWIN decouples the web application from the server, making web applications host-agnostic. For example, you can host an OWIN-based web application in IIS or self-host it in a custom process. For more information about OWIN and Katana, see What's new in OWIN and Katana. Summary Today’s Visual Studio 2013, ASP.NET and Entity Framework release delivers some fantastic new features that streamline your web development lifecycle. These feature span from server framework to data access to tooling to client-side HTML development.  They also integrate some great open-source technology and contributions from our developer community. Download and start using them today! Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• com.jcraft.jsch.JSchException: UnknownHostKey

  - by Alex

  I don't know how SSH works and I think that's a simple question. How do I fix that exception: com.jcraft.jsch.JSchException: UnknownHostKey: mywebsite.com. RSA key fingerprint is 22:fb:ee:fe:18:cd:aa:9a:9c:78:89:9f:b4:78:75:b4 I know I should verify that key or something, but there is like zero documentation for Jsch. Here is my code it's really straightforward: import com.jcraft.jsch.JSch; import com.jcraft.jsch.Session; public class ssh{ public static void main(String[] arg){ try{ JSch jsch = new JSch(); //create SSH connection String host = "mywebsite.com"; String user = "username"; String password = "123456"; Session session = jsch.getSession(user, host, 22); session.setPassword(password); session.connect(); } catch(Exception e){ System.out.println(e); } } }

• Using External GPS Device w/ Android via Bluetooth

  - by jeremynealbrown

  Hello, I am writing an Android 2.0 application that is going to be used in a somewhat remote location. There will be no internet connection available and it will be used outside of the U.S. I am considering the option of using an external Nokia or similar GPS device as a receiver/transmitter and connecting to it for use in my application via the bluetooth API. I am looking for opinions on whether or not this is even possible, if anyone has attempted it or if someone has a suggestion for some other external device or approach that would be more fitting. Link to possible external GPS device: http://europe.nokia.com/find-products/accessories/all-accessories/navigation/gps-modules/nokia-gps-module-ld-3w Thanks in advance...

However, these applications are typically expensive or unreliable.  Plus, if you have a laptop or lack a secondary computer to put the hard drive into – how on earth do you wipe it quickly and easily while still conforming to a 7 pass rule (this means that every possible bit on the hard drive is set to 0 and then to 1 seven times in a row)?  Yes, one pass should be enough – as turning every bit from a 1 to a zero will wipe the data from existence.  But, we’re dealing with tinfoil hat wearing types here people.  DOD standards dictate at least 3 passes, and typically 7 is the preferred amount.  I’m not going to argue about data recovery.  I have been told to use 7 passes, and so I will.  So say we all! Quite some time ago I used to make a BartPE XP-based boot cd for the original purpose of securely wiping data.  I loved BartPE and integrated so many plugins into my builds that I could do pretty much anything directly from CD.  Reset passwords, uninstall security updates, wipe drives, chkdsk, remove spyware, install Windows, etc.  However, with the newer multi-core systems and new chipsets coming out from vendors, I found that BartPE was rather difficult to keep up to date.  I have since switched to WinPE 3.0 (Windows Preinstallation Environment). http://technet.microsoft.com/en-us/library/cc748933(WS.10).aspx  It is fairly simple to create your own CD, and I have made a few helpful scripts to easily integrate drivers and rebuild the ISO file for you.  I’ll cover making your own boot CD utilizing WinPE 3.0 in a later post – I can talk about WinPE forever and need to collect my thoughts!!  My wife loves talking about WinPE almost as much as talking about Doctor Who.  Wait, did I say loves?  Hmmmm, I may have meant loathes. The topic at hand?  Right. Wiping a drive! I must have drunk too much coffee this morning.  I like to use a simple batch script that calls a combination of diskpart.exe from Microsoft® and Sdelete.exe created by our friend Mark Russinovich. http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx All of the following files are located within the same directory on my WinPE boot CD. Here are the contents of wipe_me.bat, script.txt and sdelete.reg. Wipe_me.bat:   @echo off echo. echo     I will completely wipe the local hard drives using echo     7 individual wipes. The data will NOT echo     be recoverable.  I will begin after you pause echo. echo Preparing to partition and format disk. Diskpart.exe /s "script.txt" REM I was annoyed by not having a completely automated script – and Sdelete wants you to accept the license agreement. So, I added a registry file to skip doing that. regedit /S sdelete.reg rem sdelete options selected are: -p (passes) -c (zero free space) -s (recurse through subdirectories, if any) -z (clean free space) [drive letter] sdelete.exe -p 7 -c -s -z c: echo. echo Pass seven complete. echo. echo Wiping complete. Pause exit script.txt: list disk select disk 0 clean create partition primary select partition 1 active format FS=NTFS LABEL="New Volume" QUICK assign letter=c exit *Notes: This script assumes one local hard drive – change the script as you see fit for your environment.  The clean command will overwrite the master boot record and any hidden sector information – so be careful!   sdelete.reg: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Sysinternals\SDelete] "EulaAccepted"=dword:00000001   With a combination of WinPE, sdelete.exe and your friendly neighborhood text editor you can begin wiping drives as quickly and easily as possible!  I hope this helps, I get asked this a lot in my line of work. Best of luck, Derek

  Quick question which I hope is easily answered.. I am following this tutorial: http://oreilly.com/pub/a/ruby/archive/rails.html?page=2 and all is going well until I try create a controller and view it in my browser. The server is running and it shows the default page okay (http://127.0.0.1:3000). I ran ruby script\generate controller MyTest in my command line and it generated the correct folders and files. The problem is, when I go to http://127.0.0.1:3000/My%5FTest/ it says: We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly.

• Silverlight Ftp Upload

  - by Curtis

  Hi I'm working on trying to ftp a file to the server through a silverlight application. Where the location to upload the file on server file system, exists outside the sandbox area for the web server. In this case the web server root exists at "C:\test\www\" and the location to upload the file will exist at "C:\User\Uploads". In this scenerio i'm not sure if Http POST will work (doesn't that use the web server root). I just need to upload the file selected by the user to a different location that may exist outside the sandbox. With silverlight i'm thinking sockets are my last option based on the limited port range for silverlight being 4502-4532. Can i do this using WebClient and Http POST? Can i make an ftp connection through silverlight or javascript?

• AssemblyCleanup() after test fail/exception

  - by Tommy Jakobsen

  Hello, I'm running a few unit tests that requires a connection to the database. When my test project get initialized, a snapshot of the database is created, and when tests are done the database gets restored back to the snapshot. Here is the implementation: [TestClass] public static class AssemblyInitializer { [AssemblyInitialize()] public static void AssemblyInit(TestContext context) { var dbss = new DatabaseSnapshot(...); dbss.CreateSnapshot(); } [AssemblyCleanup()] public static void AssemblyCleanup() { var dbss = new DatabaseSnapshot(...); dbss.RevertDatabase(); } } Now this all works, but my problem arise when I have a failing test or some exception. The AssemblyCleanup is of course not invoked, so how can I solve this problem? No matter what happens, the snapshot has to be restored. Is this possible?

  Does anyone know of a tutorial for using TeamCity with github with ssh private keys. I have tried to set up git hub to connect and I either get a authentication error or get access denied. I am running TeamCity on Windows 2003. I am running the build agent as a custom account. I am running the web server under the administrator account. I have create a key for the custom account and administrator account. I now get an error that: The connection test failed: com.jcraft.jsch.JSchException: java.io.FileNotFoundException: C:\Documents and Settings\Administrator.ssh (Access is denied) If anyone has successfully set this up please help. I am going on 3 hours into this and want to get it solved. Thanks.

• Embed SQL Password into Crystal Reports RPT file?

  - by codeulike

  We are experimenting with Crystal Reports viewers such as this one: http://www.thereportviewer.com/ ... which can actually re-connect to the data source and re-run a Crystal Reports RPT file with live data. However when running the report the viewer asks for a password to connect to the data source (in this case SQL Server). Does Crystal Reports have some way of embedding a connection password into a RPT file to avoid this? Or should I be using a System DSN from the Control Panel/ODBC thing to get around this? I figure someone else must have had this problem.

• filter data between 2 dates in crystal report vb.net

  - by irienaoki0407

  I need some help for creating Crystal Reports in VB 2005. I want to filter data between two dates (like from date and to date) with datetimepicker. I'm using SQL Server 2000 for the connection. Update: Thanks for the link, but I'm trying using record selection formula.... Here's my code: Try Dim cryRpt As New ReportDocument With cryRpt .FileName = ("C:\Documents and Settings\Ratna Ayu\My Documents\Visual Studio 2005\Projects\Denda\Denda\CrystalReport1.rpt") .RecordSelectionFormula = "{pinjam.tglkembali}>='" & DateTimePicker1.Value.ToString("dd/MM/yyyy") & "' and {pinjam.tglkembali} =<'" & DateTimePicker2.Value.ToString("dd/MM/yyyy") & "'" End With CrystalReportViewer1.ReportSource = cryRpt CrystalReportViewer1.Refresh() Catch ex As Exception MsgBox("tdk ada data", , "") End Try

• How To debug Android app on Emulator using NetBeans IDE

  - by tobrien

  I recently downloaded the latest NetBeans IDE (for MACOSX) and imported/migrated a project over from the ECLIPSE environment. Everything looks, and works well... except that EMULATOR gets stuck "waiting for the debugger to attach." I tried "Attaching Debugger..." and set the PORT value to every case I've ever read about (8200, 8700, 5555, etc.) but the connection is refused. I am of the opinion that this is not the preferred way to start a debugging session in NetBeans for Android. What am I missing?

• SSIS Configuration error: Cannot retrieve configuration table schema

  - by Glenn M

  I'm trying to add a simple configuration to a SSIS package, of type SQL Server, so stored in a table. At the end of the wizard, when it goes to try and write a new row to the nominated table to store the configuration it fails with the error: TITLE: Microsoft Visual Studio Could not complete wizard actions. Cannot retrieve configuration table schema. (Microsoft.DataTransformationServices.Wizards) I can't seem to resolve this. The configuration connection has full permissions on the table, and it sees it and can read from it as it reports there is no current data for the filter I provide. It just wont write to it. A Google search of the error message above in quotes returns literally no hits! Any suggestions? Glenn

• OpenVPN not connecting

  There have been a number of post similar to this, but none seem to satisfy my need. Plus I am a Ubuntu newbie. I followed this tutorial to completely set up OpenVPN on Ubuntu 12.04 server.

• Long held AJAX connections being blocked by Anti-Virus

  - by jeffreyveon

  Ok, this is downright bizarre. I am building a web application that relies on long held HTTP connection using COMET, and using this to stream data from the server to the application. Now, the problem is that this does not seem to go well with some anti-virus programs. We are now on beta, and some users are facing problems with the application when the anti-virus is enabled. It's not just one specific anti-virus either..

• Consuming WebSphere service from WCF client: Unable to create AxisService from ServiceEndpointAddres

  - by JohnIdol

  I am consuming (or trying to consume) a WebSphere service from a WCF client (service reference + bindings generated through svcutil). Connection seems to be established successfully but I am getting the following error: CWWSS7200E: Unable to create AxisService from ServiceEndpointAddress [address] Rings any bell? I am guessing the request format is somehow being rejected by the service, I am sniffing it with fiddler and it looks fine overall (can post if ppl think it could help). Found this article, but it doesn't seem to apply to my case. Any help appreciated!
