  • ASPNET WebAPI REST Guidance

    - by JoshReuben
    ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework. While I may be more partial to NodeJS these days, there is no denying that WebAPI is a well engineered framework. What follows is my investigation of how to leverage WebAPI to construct a RESTful frontend API.   The Advantages of REST Methodology over SOAP Simpler API for CRUD ops Standardize Development methodology - consistent and intuitive Standards based à client interop Wide industry adoption, Ease of use à easy to add new devs Avoid service method signature blowout Smaller payloads than SOAP Stateless à no session data means multi-tenant scalability Cache-ability Testability   General RESTful API Design Overview · utilize HTTP Protocol - Usage of HTTP methods for CRUD, standard HTTP response codes, common HTTP headers and Mime Types · Resources are mapped to URLs, actions are mapped to verbs and the rest goes in the headers. · keep the API semantic, resource-centric – A RESTful, resource-oriented service exposes a URI for every piece of data the client might want to operate on. A REST-RPC Hybrid exposes a URI for every operation the client might perform: one URI to fetch a piece of data, a different URI to delete that same data. utilize Uri to specify CRUD op, version, language, output format: http://api.MyApp.com/{ver}/{lang}/{resource_type}/{resource_id}.{output_format}?{key&filters} · entity CRUD operations are matched to HTTP methods: · Create - POST / PUT · Read – GET - cacheable · Update – PUT · Delete - DELETE · Use Uris to represent a hierarchies - Resources in RESTful URLs are often chained · Statelessness allows for idempotency – apply an op multiple times without changing the result. POST is non-idempotent, the rest are idempotent (if DELETE flags records instead of deleting them). · Cache indication - Leverage HTTP headers to label cacheable content and indicate the permitted duration of cache · PUT vs POST - The client uses PUT when it determines which URI (Id key) the new resource should have. The client uses POST when the server determines they key. PUT takes a second param – the id. POST creates a new resource. The server assigns the URI for the new object and returns this URI as part of the response message. Note: The PUT method replaces the entire entity. That is, the client is expected to send a complete representation of the updated product. If you want to support partial updates, the PATCH method is preferred DELETE deletes a resource at a specified URI – typically takes an id param · Leverage Common HTTP Response Codes in response headers 200 OK: Success 201 Created - Used on POST request when creating a new resource. 304 Not Modified: no new data to return. 400 Bad Request: Invalid Request. 401 Unauthorized: Authentication. 403 Forbidden: Authorization 404 Not Found – entity does not exist. 406 Not Acceptable – bad params. 409 Conflict - For POST / PUT requests if the resource already exists. 500 Internal Server Error 503 Service Unavailable · Leverage uncommon HTTP Verbs to reduce payload sizes HEAD - retrieves just the resource meta-information. OPTIONS returns the actions supported for the specified resource. PATCH - partial modification of a resource. · When using PUT, POST or PATCH, send the data as a document in the body of the request. Don't use query parameters to alter state. · Utilize Headers for content negotiation, caching, authorization, throttling o Content Negotiation – choose representation (e.g. JSON or XML and version), language & compression. Signal via RequestHeader.Accept & ResponseHeader.Content-Type Accept: application/json;version=1.0 Accept-Language: en-US Accept-Charset: UTF-8 Accept-Encoding: gzip o Caching - ResponseHeader: Expires (absolute expiry time) or Cache-Control (relative expiry time) o Authorization - basic HTTP authentication uses the RequestHeader.Authorization to specify a base64 encoded string "username:password". can be used in combination with SSL/TLS (HTTPS) and leverage OAuth2 3rd party token-claims authorization. Authorization: Basic sQJlaTp5ZWFslylnaNZ= o Rate Limiting - Not currently part of HTTP so specify non-standard headers prefixed with X- in the ResponseHeader. X-RateLimit-Limit: 10000 X-RateLimit-Remaining: 9990 · HATEOAS Methodology - Hypermedia As The Engine Of Application State – leverage API as a state machine where resources are states and the transitions between states are links between resources and are included in their representation (hypermedia) – get API metadata signatures from the response Link header - in a truly REST based architecture any URL, except the initial URL, can be changed, even to other servers, without worrying about the client. · error responses - Do not just send back a 200 OK with every response. Response should consist of HTTP error status code (JQuery has automated support for this), A human readable message , A Link to a meaningful state transition , & the original data payload that was problematic. · the URIs will typically map to a server-side controller and a method name specified by the type of request method. Stuff all your calls into just four methods is not as crazy as it sounds. · Scoping - Path variables look like you’re traversing a hierarchy, and query variables look like you’re passing arguments into an algorithm · Mapping URIs to Controllers - have one controller for each resource is not a rule – can consolidate - route requests to the appropriate controller and action method · Keep URls Consistent - Sometimes it’s tempting to just shorten our URIs. not recommend this as this can cause confusion · Join Naming – for m-m entity relations there may be multiple hierarchy traversal paths · Routing – useful level of indirection for versioning, server backend mocking in development ASPNET WebAPI Considerations ASPNET WebAPI implements a lot (but not all) RESTful API design considerations as part of its infrastructure and via its coding convention. Overview When developing an API there are basically three main steps: 1. Plan out your URIs 2. Setup return values and response codes for your URIs 3. Implement a framework for your API.   Design · Leverage Models MVC folder · Repositories – support IoC for tests, abstraction · Create DTO classes – a level of indirection decouples & allows swap out · Self links can be generated using the UrlHelper · Use IQueryable to support projections across the wire · Models can support restful navigation properties – ICollection<T> · async mechanism for long running ops - return a response with a ticket – the client can then poll or be pushed the final result later. · Design for testability - Test using HttpClient , JQuery ( $.getJSON , $.each) , fiddler, browser debug. Leverage IDependencyResolver – IoC wrapper for mocking · Easy debugging - IE F12 developer tools: Network tab, Request Headers tab     Routing · HTTP request method is matched to the method name. (This rule applies only to GET, POST, PUT, and DELETE requests.) · {id}, if present, is matched to a method parameter named id. · Query parameters are matched to parameter names when possible · Done in config via Routes.MapHttpRoute – similar to MVC routing · Can alternatively: o decorate controller action methods with HttpDelete, HttpGet, HttpHead,HttpOptions, HttpPatch, HttpPost, or HttpPut., + the ActionAttribute o use AcceptVerbsAttribute to support other HTTP verbs: e.g. PATCH, HEAD o use NonActionAttribute to prevent a method from getting invoked as an action · route table Uris can support placeholders (via curly braces{}) – these can support default values and constraints, and optional values · The framework selects the first route in the route table that matches the URI. Response customization · Response code: By default, the Web API framework sets the response status code to 200 (OK). But according to the HTTP/1.1 protocol, when a POST request results in the creation of a resource, the server should reply with status 201 (Created). Non Get methods should return HttpResponseMessage · Location: When the server creates a resource, it should include the URI of the new resource in the Location header of the response. public HttpResponseMessage PostProduct(Product item) {     item = repository.Add(item);     var response = Request.CreateResponse<Product>(HttpStatusCode.Created, item);     string uri = Url.Link("DefaultApi", new { id = item.Id });     response.Headers.Location = new Uri(uri);     return response; } Validation · Decorate Models / DTOs with System.ComponentModel.DataAnnotations properties RequiredAttribute, RangeAttribute. · Check payloads using ModelState.IsValid · Under posting – leave out values in JSON payload à JSON formatter assigns a default value. Use with RequiredAttribute · Over-posting - if model has RO properties à use DTO instead of model · Can hook into pipeline by deriving from ActionFilterAttribute & overriding OnActionExecuting Config · Done in App_Start folder > WebApiConfig.cs – static Register method: HttpConfiguration param: The HttpConfiguration object contains the following members. Member Description DependencyResolver Enables dependency injection for controllers. Filters Action filters – e.g. exception filters. Formatters Media-type formatters. by default contains JsonFormatter, XmlFormatter IncludeErrorDetailPolicy Specifies whether the server should include error details, such as exception messages and stack traces, in HTTP response messages. Initializer A function that performs final initialization of the HttpConfiguration. MessageHandlers HTTP message handlers - plug into pipeline ParameterBindingRules A collection of rules for binding parameters on controller actions. Properties A generic property bag. Routes The collection of routes. Services The collection of services. · Configure JsonFormatter for circular references to support links: PreserveReferencesHandling.Objects Documentation generation · create a help page for a web API, by using the ApiExplorer class. · The ApiExplorer class provides descriptive information about the APIs exposed by a web API as an ApiDescription collection · create the help page as an MVC view public ILookup<string, ApiDescription> GetApis()         {             return _explorer.ApiDescriptions.ToLookup(                 api => api.ActionDescriptor.ControllerDescriptor.ControllerName); · provide documentation for your APIs by implementing the IDocumentationProvider interface. Documentation strings can come from any source that you like – e.g. extract XML comments or define custom attributes to apply to the controller [ApiDoc("Gets a product by ID.")] [ApiParameterDoc("id", "The ID of the product.")] public HttpResponseMessage Get(int id) · GlobalConfiguration.Configuration.Services – add the documentation Provider · To hide an API from the ApiExplorer, add the ApiExplorerSettingsAttribute Plugging into the Message Handler pipeline · Plug into request / response pipeline – derive from DelegatingHandler and override theSendAsync method – e.g. for logging error codes, adding a custom response header · Can be applied globally or to a specific route Exception Handling · Throw HttpResponseException on method failures – specify HttpStatusCode enum value – examine this enum, as its values map well to typical op problems · Exception filters – derive from ExceptionFilterAttribute & override OnException. Apply on Controller or action methods, or add to global HttpConfiguration.Filters collection · HttpError object provides a consistent way to return error information in the HttpResponseException response body. · For model validation, you can pass the model state to CreateErrorResponse, to include the validation errors in the response public HttpResponseMessage PostProduct(Product item) {     if (!ModelState.IsValid)     {         return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState); Cookie Management · Cookie header in request and Set-Cookie headers in a response - Collection of CookieState objects · Specify Expiry, max-age resp.Headers.AddCookies(new CookieHeaderValue[] { cookie }); Internet Media Types, formatters and serialization · Defaults to application/json · Request Accept header and response Content-Type header · determines how Web API serializes and deserializes the HTTP message body. There is built-in support for XML, JSON, and form-urlencoded data · customizable formatters can be inserted into the pipeline · POCO serialization is opt out via JsonIgnoreAttribute, or use DataMemberAttribute for optin · JSON serializer leverages NewtonSoft Json.NET · loosely structured JSON objects are serialzed as JObject which derives from Dynamic · to handle circular references in json: json.SerializerSettings.PreserveReferencesHandling =    PreserveReferencesHandling.All à {"$ref":"1"}. · To preserve object references in XML [DataContract(IsReference=true)] · Content negotiation Accept: Which media types are acceptable for the response, such as “application/json,” “application/xml,” or a custom media type such as "application/vnd.example+xml" Accept-Charset: Which character sets are acceptable, such as UTF-8 or ISO 8859-1. Accept-Encoding: Which content encodings are acceptable, such as gzip. Accept-Language: The preferred natural language, such as “en-us”. o Web API uses the Accept and Accept-Charset headers. (At this time, there is no built-in support for Accept-Encoding or Accept-Language.) · Controller methods can take JSON representations of DTOs as params – auto-deserialization · Typical JQuery GET request: function find() {     var id = $('#prodId').val();     $.getJSON("api/products/" + id,         function (data) {             var str = data.Name + ': $' + data.Price;             $('#product').text(str);         })     .fail(         function (jqXHR, textStatus, err) {             $('#product').text('Error: ' + err);         }); }            · Typical GET response: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Mon, 18 Jun 2012 04:30:33 GMT X-AspNet-Version: 4.0.30319 Cache-Control: no-cache Pragma: no-cache Expires: -1 Content-Type: application/json; charset=utf-8 Content-Length: 175 Connection: Close [{"Id":1,"Name":"TomatoSoup","Price":1.39,"ActualCost":0.99},{"Id":2,"Name":"Hammer", "Price":16.99,"ActualCost":10.00},{"Id":3,"Name":"Yo yo","Price":6.99,"ActualCost": 2.05}] True OData support · Leverage Query Options $filter, $orderby, $top and $skip to shape the results of controller actions annotated with the [Queryable]attribute. [Queryable]  public IQueryable<Supplier> GetSuppliers()  · Query: ~/Suppliers?$filter=Name eq ‘Microsoft’ · Applies the following selection filter on the server: GetSuppliers().Where(s => s.Name == “Microsoft”)  · Will pass the result to the formatter. · true support for the OData format is still limited - no support for creates, updates, deletes, $metadata and code generation etc · vnext: ability to configure how EditLinks, SelfLinks and Ids are generated Self Hosting no dependency on ASPNET or IIS: using (var server = new HttpSelfHostServer(config)) {     server.OpenAsync().Wait(); Tracing · tracability tools, metrics – e.g. send to nagios · use your choice of tracing/logging library, whether that is ETW,NLog, log4net, or simply System.Diagnostics.Trace. · To collect traces, implement the ITraceWriter interface public class SimpleTracer : ITraceWriter {     public void Trace(HttpRequestMessage request, string category, TraceLevel level,         Action<TraceRecord> traceAction)     {         TraceRecord rec = new TraceRecord(request, category, level);         traceAction(rec);         WriteTrace(rec); · register the service with config · programmatically trace – has helper extension methods: Configuration.Services.GetTraceWriter().Info( · Performance tracing - pipeline writes traces at the beginning and end of an operation - TraceRecord class includes aTimeStamp property, Kind property set to TraceKind.Begin / End Security · Roles class methods: RoleExists, AddUserToRole · WebSecurity class methods: UserExists, .CreateUserAndAccount · Request.IsAuthenticated · Leverage HTTP 401 (Unauthorized) response · [AuthorizeAttribute(Roles="Administrator")] – can be applied to Controller or its action methods · See section in WebApi document on "Claim-based-security for ASP.NET Web APIs using DotNetOpenAuth" – adapt this to STS.--> Web API Host exposes secured Web APIs which can only be accessed by presenting a valid token issued by the trusted issuer. http://zamd.net/2012/05/04/claim-based-security-for-asp-net-web-apis-using-dotnetopenauth/ · Use MVC membership provider infrastructure and add a DelegatingHandler child class to the WebAPI pipeline - http://stackoverflow.com/questions/11535075/asp-net-mvc-4-web-api-authentication-with-membership-provider - this will perform the login actions · Then use AuthorizeAttribute on controllers and methods for role mapping- http://sixgun.wordpress.com/2012/02/29/asp-net-web-api-basic-authentication/ · Alternate option here is to rely on MVC App : http://forums.asp.net/t/1831767.aspx/1

  • Hablamos de Formación en la Conferencia Total Training en Lisboa

    - by Julio Rodriguez
    El pasado 22 de Octubre se celebro en Lisboa la 2ª Edición del Total Training Conference, la feria de la formación en la empresa de Portugal. Este año contó con la participación de cerca de 90 profesionales de los Recursos Humanos y se trataron los temas de mayor interés para los departamentos de formación de las empresas. ¿De qué se habló en la conferencia? Los ejes principales de las ponencias estuvieron centrados en la combinación de formación presencial y elearning, para sacar el máximo provecho de los presupuestos de formación y utilizar el medio adecuado para impactar de la manera más efectiva en los alumnos, ya estemos tratando de inculcar valores o comportamientos o simplemente transmitiendo una serie de conocimientos que tienen que ser utilizados en el día a día. Tambien se trato de los aspectos de aprendizajes informales, también conocidos como social learning, o cómo podemos transformar a nuestros empleados en profesores de sus compañeros resolviendo necesidades puntuales, pero a veces críticas. En la última ponencia se explicó y trató el novedoso tema de la gamificación o cómo introducir en la generación de contenidos formativos elementos lúdicos del juego para aumentar la efectividad de los mismos, concretando las definiciones y aclarando que formación no es una gamificación aunque por su similitud pueda confundirse. ¿Qué aportó Oracle a esta jornada? Desde Oracle quisimos aportar nuestro granito de arena, explicando los beneficios de una solución de formación en la nube, dónde, desde el punto de vista de funcionalidad no se renuncia a nada que pueda ofrecer una solución onpremise, con una serie de ventajas adicionales, como son: Pagar por uso y no hay que hacer desembolsos iniciales importantes como el pago de licencias o la compra de servidores o la contratación o asignación de personal informático para mantener un sistema en la casa. Así mismo al ser mantenida por el propio fabricante, el sistema es actualizado de forma constante, de forma transparente para el propio cliente sin los quebraderos de cabeza típicos de esos proyectos de implantación. Aprovechamos la ocasión para comentar algunos de los proyectos transformacionales de algunos de nuestros clientes para ilustrar como un sistema de formación puede por ejemplo convertir a un departamento que es un centro de coste en un centro de beneficio, o cómo un despliegue adecuado de la formación puede reducir la rotación, aumentar la satisfacción de los empleados y ayudar en el despliegue de nuevos productos. En definitiva una jornada de lo más provechosa si eres un profesional de la formación en Portugal Si quieres conocer las soluciones de elearning de Oracle las encontrarás aquí

  • SPRoleAssignment Crazy Caviats

    - by MOSSLover
    I’m not sure if this bug exists on any other environment, but here are a few issues I ran into when trying to use SPRoleAssignment and SPGroup: When trying to use Web.Groups[“GroupName”] it basically told me the group did not exist, so I had to change the code to use Web.SiteGroups[“GroupName”]. I could not add the Role Assignment to the Web and run a Web.Update() without adding an additional Web.AllowUnsafeUpdates= true; , however on my virtual machine I could do a Web.Update() without the extra piece of code.  I kept receiving an error in my browser stating that I should hit the back button and update my permissions. So after fixing those two issues I was able to copy the permissions from a page item into a Site for my migration.  Hopefully, one of you can learn from my error messages if you have any issues in the future.

  • Android - Switching Activities with a Tab Layout

    - by Bill Osuch
    This post is based on the Tab Layout  tutorial on the Android developers site, with some modifications. I wanted to get rid of the icons (they take up too much screen real estate), and modify the fonts on the tabs. First, create a new Android project, with an Activity called TabWidget. Then, create two additional Activities called TabOne and TabTwo. Throw a simple TextView on each one with a message identifying the tab, like this: public class TabTwo extends Activity {  @Override  public void onCreate(Bundle savedInstanceState) {   super.onCreate(savedInstanceState);   TextView tv = new TextView(this);   tv.setText("This is tab 2");   setContentView(tv);  } } And don't forget to add them to your AndroidManifest.xml file: <activity android:name=".TabOne"></activity> <activity android:name=".TabTwo"></activity> Now we'll create the tab layout - open the res/layout/main.xml file and insert the following: <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android"  android:id="@android:id/tabhost"  android:layout_width="fill_parent"  android:layout_height="fill_parent">  <LinearLayout   android:orientation="vertical"   android:layout_width="fill_parent"   android:layout_height="fill_parent">   <TabWidget    android:id="@android:id/tabs"    android:layout_width="fill_parent"    android:layout_height="wrap_content" />   <FrameLayout    android:id="@android:id/tabcontent"             android:layout_width="fill_parent"    android:layout_height="fill_parent" />  </LinearLayout> </TabHost> Finally, we'll create the code needed to populate the TabHost. Make sure your TabWidget class extends TabActivity rather than Activity, and add code to grab the TabHost and create an Intent to launch a new Activity:    TabHost tabHost = getTabHost();  // The activity TabHost    TabHost.TabSpec spec;  // Reusable TabSpec for each tab    Intent intent;  // Reusable Intent for each tab       // Create an Intent to launch an Activity for the tab (to be reused)    intent = new Intent().setClass(this, TabOne.class); Add the first tab to the layout:    // Initialize a TabSpec for each tab and add it to the TabHost    spec = tabHost.newTabSpec("tabOne");      spec.setContent(intent);     spec.setIndicator("Tab One");     tabHost.addTab(spec); It's pretty tall as-is, so we'll shorten it:   // Squish the tab a little bit horizontally   tabHost.getTabWidget().getChildAt(0).getLayoutParams().height = 40; But the text is a little small, so let's increase the font size:   // Bump the text size up   LinearLayout ll = (LinearLayout) tabHost.getChildAt(0);   android.widget.TabWidget tw = (android.widget.TabWidget) ll.getChildAt(0);   RelativeLayout rllf = (RelativeLayout) tw.getChildAt(0);   TextView lf = (TextView) rllf.getChildAt(1);   lf.setTextSize(20); Do the same for the second tab, and you wind up with this: @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);                 TabHost tabHost = getTabHost();  // The activity TabHost         TabHost.TabSpec spec;  // Reusable TabSpec for each tab         Intent intent;  // Reusable Intent for each tab            // Create an Intent to launch an Activity for the tab (to be reused)         intent = new Intent().setClass(this, TabOne.class);         // Initialize a TabSpec for each tab and add it to the TabHost         spec = tabHost.newTabSpec("tabOne");           spec.setContent(intent);          spec.setIndicator("Tab One");          tabHost.addTab(spec);         // Squish the tab a little bit horizontally         tabHost.getTabWidget().getChildAt(0).getLayoutParams().height = 40;         // Bump the text size up         LinearLayout ll = (LinearLayout) tabHost.getChildAt(0);         android.widget.TabWidget tw = (android.widget.TabWidget) ll.getChildAt(0);         RelativeLayout rllf = (RelativeLayout) tw.getChildAt(0);         TextView lf = (TextView) rllf.getChildAt(1);         lf.setTextSize(20);            // Do the same for the other tabs         intent = new Intent().setClass(this, TabTwo.class);         spec = tabHost.newTabSpec("tabTwo");          spec.setContent(intent);          spec.setIndicator("Tab Two");         tabHost.addTab(spec);         tabHost.getTabWidget().getChildAt(1).getLayoutParams().height = 40;         RelativeLayout rlrf = (RelativeLayout) tw.getChildAt(1);         TextView rf = (TextView) rlrf.getChildAt(1);         rf.setTextSize(20);            tabHost.setCurrentTab(0);     } Save and fire up the emulator, and you should be able to switch back and forth between your tabs!

  • Current Technologies

    - by Charles Cline
    I currently work at the University of Kansas (KU) and before that Stanford University, to be particular the Stanford Linear Accelerator Center (SLAC).  Collaborating with various Higher Ed institutions the past several years has shown a marked increase in the Microsoft side of the house.  To give you an idea of our current environment, here are some of the things we (Enterprise Systems) have been working on the past two years I’ve been at KU: Migrated from Novell to Active Directory (AD), although we’re still leveraging Novell for IDM.  We currently have 550,000+ objects in AD, and we still have several departments to bring in. Upgraded from Exchange 2003 to Exchange 2010 and Forefront Online Protection for Exchange (FOPE) Implemented SCCM 2007 for Windows systems management Implemented central file storage using EMC products for the backend, using CIFS as the frontend Restructuring AD domains and Forests to decrease the administrative overhead and provide a primary authentication mechanism for the entire University Determining Key Performance Indicators for AD and Exchange Implemented SCOM 2007 to monitor AD and Exchange Implemented Confluence for collaboration within IT and other technology providers at the University Implemented Data Protection Manager (DPM) for backup of AD and Exchange Built a test and QA environment to better facilitate upcoming changes to the environment Almost ready to raise the AD domain level to 2008 R2   I’m sure I’m missing things, and my next post will be some of the things we’re getting ready for – like Centrify to provide AD for OS X and Linux systems.  If anyone would like more info on a particular area, please drop me a line.  I’d be happy to discuss.

  • Movember 2012

    - by Tim Koekkoek
    If you were lucky enough to visit one of the Oracle Dublin offices during the month November you may have noticed a bunch of mustached merchants. If you thought the mustache was the newest hair fashion in Ireland you were wrong. These guys were the Mo Bro’s and proud members of MOracle, our Movember 2012 team. The aim of Movember is to raise vital funds and awareness for men’s health, especially prostate cancer. To raise these funds, men don't shave their upper lips for a whole month and get sponsored for it by friends, family and colleagues. To highlight the importance of supporting this cause, take a look at these statistics: •             1 out of 8 men will be diagnosed with prostate cancer during their life. •             This year more than 2,000 new cases of disease will be diagnosed. •             1 out of 3 men will be diagnosed with cancer during their life. It was a long and heavy month for all the Mo Bro’s, but in the end the effort has paid off. Under the leadership of team captain Jimmy this team managed to raise over €4,400  and was ranked #34 out of 1142 Irish Movember teams. The team couldn't have done it without the constant support of our colleagues and sponsors. Many thanks to all of you! We are very happy to have raised money and awareness for men’s health. On top of that we are also happy to have raised awareness for the most underrated and abandoned piece of man’s hair… the mustache. This is just the beginning; soon many men will proudly wear this fashionable look again!

  • Recording Topics manually and automatically

    - by maria.cozzolino(at)oracle.com
    When you are recording UPK topics, the default mode for recording is manual recording, where you tell the system when to record each screen shot. This mode allows you to take the exact screen shot you need. However, it does get a bit tedious when you are recording long topics, especially if you forget to take a few screen shots. In UPK 3.5, a new version of recording was introduced - Automatic Recording. It was designed to simplify the recording process by automatically capturing screen shots as you perform your transaction. If you haven't experimented with Automatic Recording, I'd recommend you give it a try - it might make your recording life easier. If you are recording with sound, you can also narrate your topic while recording it. To turn on Automatic Recording: 1. In Tools/Options, there are two recorder tabs. The first tab, under content defaults, includes settings that you may want to share between developers, like whether keyboard shortcuts are automatically captured. 2. The second tab is the one that contains the personal preferences, like screen shot capture key and whether to record automatically or manually. On this tab, choose the option for Automatic Recording. 3. Save the settings. Note that this setting will NOT impact content defaults; this is for your user only. When you launch the recorder, you will notice a slightly different message with guidance on how to start and stop automatic recording. Once you start recording, the recorder window is hidden until the end of the recording session to allow you to capture your transaction. In the task tray, there is a series of icons that let you know that you are capturing content. You can pause the recording, as well as set and view your sound levels if you are using sound. A camera appears during each screen capture to help you know when the system is capturing a screen shot, and a context indicator appears to show the recognition. With automatic recording, you can let the system capture the necessary screen shots. It may provide a more natural recording experience, and is probably easier for the untrained developer. On the other hand, you have a bit more control with manual recording on which screen shot appears, but it also means you have to remember to capture the screen shot. :) We'd be interested in hearing which type of recording you do, and any rationale on why you made that choice. Please comment and let us know. --Maria Cozzolino, Manager of UPK Software Requirements and UI Design

  • Database .NET

    - by Guilherme Cardoso
    Database .NET is an awesome tool that allow us manage several database in simultaneous (SQL Server, MySQL, Oracle, etc). What lead me to install this tool was an problem that must be shared by must developers. Tools like SQL Server Management Studio consume to many resources, and if you don't have a decent computer you'll get problems in performance, and that's my case! With Database .NET we can access an SQL Server for example, and make several actions to database (crud operations, manage procedures, etc).Of course that this tool can replace the use of SQL Server Management Studio for example!  But it's really usefull if  you just need to perform small operations because it consumes many fewer resources. This tool don't need to be installed (it can be used as an portable application). One tip: if you are using SQL Server Express for example, don't forget to check the server name in Database .NET connection. In my case i've to change from GUILHERM-196634 to GUILHERM-196634\SQLExpress. Project: http://fishcodelib.com/Database.htm Download: http://fishcodelib.com/files/DatabaseNet3.zip

  • SSAS deployment error: Internal error: Invalid enumeration value. Please call customer support! is not a valid value for this element.

    - by Kevin Shyr
    The first search on this error yielded some blog posts that says to check SQL server version.  It suggested that I couldn't deploy a SSAS project originally set for SSAS 2008 to a SSAS 2008 R2, which didn't make sense to me.  Combined with the fact that the error message was telling me to call customer support.  Why do I need to call customer support unless something catastrophic happened?Turns out that one of the file on the SQL server is corrupt.  I could simply delete the database on the SSAS server and re-run deployment.  Problem solved.SSAS errors in visual studio: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* 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:0in; mso-para-margin-bottom:.0001pt; 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-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Error      10           Internal error: Invalid enumeration value.

  • Multithreading in Windows Phone 7 emulator: A bug

    - by Laurent Bugnion
    Multithreading is supported in Windows Phone 7 Silverlight applications, however the emulator has a bug (which I discovered and was confirmed to me by the dev lead of the emulator team): If you attempt to start a background thread in the MainPage constructor, the thread never starts. The reason is a problem with the emulator UI thread which doesn’t leave any time to the background thread to start. Thankfully there is a workaround (see code below). Also, the bug should be corrected in a future release, so it’s not a big deal, even though it is really confusing when you try to understand why the *%&^$£% thread is not &$%&%$£ starting (that was me in the plane the other day ;) This code does not work: public partial class MainPage : PhoneApplicationPage { public MainPage() { InitializeComponent(); SupportedOrientations = SupportedPageOrientation.Portrait | SupportedPageOrientation.Landscape; var counter = 0; ThreadPool.QueueUserWorkItem(o => { while (true) { Dispatcher.BeginInvoke(() => { textBlockListTitle.Text = (counter++).ToString(); }); } }); } } This code does work: public MainPage() { InitializeComponent(); SupportedOrientations = SupportedPageOrientation.Portrait | SupportedPageOrientation.Landscape; var counter = 0; ThreadPool.QueueUserWorkItem(o => { while (true) { Dispatcher.BeginInvoke(() => { textBlockListTitle.Text = (counter++).ToString(); }); // NOTICE THIS LINE!!! Thread.Sleep(0); } }); } Note that even if the thread is started in a later event (for example Click of a Button), the behavior without the Thread.Sleep(0) is not good in the emulator. As of now, i would recommend always sleeping when starting a new thread. Happy coding: Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Cloud Computing = Elasticity * Availability

    - by Herve Roggero
    What is cloud computing? Is hosting the same thing as cloud computing? Are you running a cloud if you already use virtual machines? What is the difference between Infrastructure as a Service (IaaS) and a cloud provider? And the list goes on… these questions keep coming up and all try to fundamentally explain what “cloud” means relative to other concepts. At the risk of over simplification, answering these questions becomes simpler once you understand the primary foundations of cloud computing: Elasticity and Availability.   Elasticity The basic value proposition of cloud computing is to pay as you go, and to pay for what you use. This implies that an application can expand and contract on demand, across all its tiers (presentation layer, services, database, security…).  This also implies that application components can grow independently from each other. So if you need more storage for your database, you should be able to grow that tier without affecting, reconfiguring or changing the other tiers. Basically, cloud applications behave like a sponge; when you add water to a sponge, it grows in size; in the application world, the more customers you add, the more it grows. Pure IaaS providers will provide certain benefits, specifically in terms of operating costs, but an IaaS provider will not help you in making your applications elastic; neither will Virtual Machines. The smallest elasticity unit of an IaaS provider and a Virtual Machine environment is a server (physical or virtual). While adding servers in a datacenter helps in achieving scale, it is hardly enough. The application has yet to use this hardware.  If the process of adding computing resources is not transparent to the application, the application is not elastic.   As you can see from the above description, designing for the cloud is not about more servers; it is about designing an application for elasticity regardless of the underlying server farm.   Availability The fact of the matter is that making applications highly available is hard. It requires highly specialized tools and trained staff. On top of it, it's expensive. Many companies are required to run multiple data centers due to high availability requirements. In some organizations, some data centers are simply on standby, waiting to be used in a case of a failover. Other organizations are able to achieve a certain level of success with active/active data centers, in which all available data centers serve incoming user requests. While achieving high availability for services is relatively simple, establishing a highly available database farm is far more complex. In fact it is so complex that many companies establish yearly tests to validate failover procedures.   To a certain degree certain IaaS provides can assist with complex disaster recovery planning and setting up data centers that can achieve successful failover. However the burden is still on the corporation to manage and maintain such an environment, including regular hardware and software upgrades. Cloud computing on the other hand removes most of the disaster recovery requirements by hiding many of the underlying complexities.   Cloud Providers A cloud provider is an infrastructure provider offering additional tools to achieve application elasticity and availability that are not usually available on-premise. For example Microsoft Azure provides a simple configuration screen that makes it possible to run 1 or 100 web sites by clicking a button or two on a screen (simplifying provisioning), and soon SQL Azure will offer Data Federation to allow database sharding (which allows you to scale the database tier seamlessly and automatically). Other cloud providers offer certain features that are not available on-premise as well, such as the Amazon SC3 (Simple Storage Service) which gives you virtually unlimited storage capabilities for simple data stores, which is somewhat equivalent to the Microsoft Azure Table offering (offering a server-independent data storage model). Unlike IaaS providers, cloud providers give you the necessary tools to adopt elasticity as part of your application architecture.    Some cloud providers offer built-in high availability that get you out of the business of configuring clustered solutions, or running multiple data centers. Some cloud providers will give you more control (which puts some of that burden back on the customers' shoulder) and others will tend to make high availability totally transparent. For example, SQL Azure provides high availability automatically which would be very difficult to achieve (and very costly) on premise.   Keep in mind that each cloud provider has its strengths and weaknesses; some are better at achieving transparent scalability and server independence than others.    Not for Everyone Note however that it is up to you to leverage the elasticity capabilities of a cloud provider, as discussed previously; if you build a website that does not need to scale, for which elasticity is not important, then you can use a traditional host provider unless you also need high availability. Leveraging the technologies of cloud providers can be difficult and can become a journey for companies that build their solutions in a scale up fashion. Cloud computing promises to address cost containment and scalability of applications with built-in high availability. If your application does not need to scale or you do not need high availability, then cloud computing may not be for you. In fact, you may pay a premium to run your applications with cloud providers due to the underlying technologies built specifically for scalability and availability requirements. And as such, the cloud is not for everyone.   Consistent Customer Experience, Predictable Cost With all its complexities, buzz and foggy definition, cloud computing boils down to a simple objective: consistent customer experience at a predictable cost.  The objective of a cloud solution is to provide the same user experience to your last customer than the first, while keeping your operating costs directly proportional to the number of customers you have. Making your applications elastic and highly available across all its tiers, with as much automation as possible, achieves the first objective of a consistent customer experience. And the ability to expand and contract the infrastructure footprint of your application dynamically achieves the cost containment objectives.     Herve Roggero is a SQL Azure MVP and co-author of Pro SQL Azure (APress).  He is the co-founder of Blue Syntax Consulting (www.bluesyntax.net), a company focusing on cloud computing technologies helping customers understand and adopt cloud computing technologies.

  • Polishing the MonologFX API

    - by HecklerMark
    Earlier this week, I released "into the wild" a new JavaFX 2.x dialog library, MonologFX, that incorporated some elements of DialogFX and new features I'd been working on over time. While I did try to get the API to a point of reasonable completion (nothing is ever truly "finished", of course!), there was one bit of functionality that I'd included without providing any real "polish": that of the button icons. Good friend and fellow JFXtras teammate José Pereda Llamas suggested I fix that oversight and provide an update (thanks much, José!), thus this post. If you'd like to take a peek at the new streamlined syntax, I've updated the earlier post; please click here if you'd like to review it. If you want to give MonologFX a try, just point your browser to GitHub to download the updated code and/or .jar. All the best,Mark

  • Oracle to Join OECD Urban Roundtable for Mayors and Ministers

    - by caroline.yu
    Oracle is pleased to announce that Bastian Fischer, vice president and general manager for EMEA, Oracle Utilities, will participate in the 2010 Organisation for Economic Co-Operation and Development (OECD) Urban Roundtable for Mayors and Ministers on 25 May in France. The roundtable, hosted by OECD Secretary General Angel Gurría, will help determine how cities can contribute to green growth incentives and address the challenges to success. The OECD is developing a global Green Growth Strategy that will identify policies and approaches that can shift production and consumption towards a clean, low-carbon and sustainable economy. Already, more than 500 European cities have signed up to the 2020 carbon pledge to reduce carbon emissions by 20 per cent in ten years. This initiative is driving the adoption of innovative technologies such as the smart gird, which deliver substantial benefits to support this mission by allowing utilities to manage their distribution grids more efficiently, reducing emissions and lowering the risk of outages. A successful smart grid infrastructure will allow green cities to manage their energy usage and succeed in their pledge to meet European targets for carbon reduction, which will undoubtedly be a discussion topic at the roundtable. For more information, visit the OECD Web site.

  • EU Digital Agenda scores 85/100

    - by trond-arne.undheim
    If the Digital Agenda was a bottle of wine and I were wine critic Robert Parker, I would say the Digital Agenda has "a great bouquet, many good elements, with astringent, dry and puckering mouth feel that will not please everyone, but still displaying some finesse. A somewhat controlled effort with no surprises and a few noticeable flaws in the delivery. Noticeably shorter aftertaste than advertised by the producers. Score: 85/100. Enjoy now". The EU Digital Agenda states that "standards are vital for interoperability" and has a whole chapter on interoperability and standards. With this strong emphasis, there is hope the EU's outdated standardization system finally is headed for reform. It has been 23 years since the legal framework of standardisation was completed by Council Decision 87/95/EEC8 in the Information and Communications Technology (ICT) sector. Standardization is market driven. For several decades the IT industry has been developing standards and specifications in global open standards development organisations (fora/consortia), many of which have transparency procedures and practices far superior to the European Standards Organizations. The Digital Agenda rightly states: "reflecting the rise and growing importance of ICT standards developed by certain global fora and consortia". Some fora/consortia, of course, are distorted, influenced by single vendors, have poor track record, and need constant vigilance, but they are the minority. Therefore, the recognition needs to be accompanied by eligibility criteria focused on openness. Will the EU reform its ICT standardization by the end of 2010? Possibly, and only if DG Enterprise takes on board that Information and Communications Technologies (ICTs) have driven half of the productivity growth in Europe over the past 15 years, a prominent fact in the EU's excellent Digital Competitiveness report 2010 published on Monday 17 May. It is ok to single out the ICT sector. It simply is the most important sector right now as it fuels growth in all other sectors. Let's not wait for the entire standardization package which may take another few years. Europe does not have time. The Digital Agenda is an umbrella strategy with deliveries from a host of actors across the Commission. For instance, the EU promises to issue "guidance on transparent ex-ante disclosure rules for essential intellectual property rights and licensing terms and conditions in the context of standard setting", by 2011 in the Horisontal Guidelines now out for public consultation by DG COMP and to some extent by DG ENTR's standardization policy reform. This is important. The EU will issue procurement guidance as interoperability frameworks are put into practice. This is a joint responsibility of several DGs, and is likely to suffer coordination problems, controversy and delays. We have seen plenty of the latter already and I have commented on the Commission's own interoperability elsewhere, with mixed luck. :( Yesterday, I watched the cartoonesque Korean western film The Good, the Bad and the Weird. In the movie (and I meant in the movie only), a bandit, a thief, and a bounty hunter, all excellent at whatever they do, fight for a treasure map. Whether that is a good analogy for the situation within the Commission, others are better judges of than I. However, as a movie fanatic, I still await the final shoot-out, and, as in the film, the only certainty is that "life is about chasing and being chased". The missed opportunity (in this case not following up the push from Member States to better define open standards based interoperability) is a casualty of the chaos ensued in the European Wild West (and I mean that in the most endearing sense, and my excuses beforehand to actors who possibly justifiably cannot bear being compared to fictional movie characters). Instead of exposing the ongoing fight, the EU opted for the legalistic use of the term "standards" throughout the document. This is a term that--to the EU-- excludes most standards used by the IT industry world wide. So, while it, for a moment, meant "weapon down", it will not lead to lasting peace. The Digital Agenda calls for the Member States to "Implement commitments on interoperability and standards in the Malmö and Granada Declarations by 2013". This is a far cry from the actual Ministerial Declarations which called upon the Commission to help them with this implementation by recognizing and further defining open standards based interoperability. Unless there is more forthcoming from the Commission, the market's judgement will be: you simply fall short. Generally, I think the EU focus now should be "from policy to practice" and the Digital Agenda does indeed stop short of tackling some highly practical issues. There is need for progress beyond the Digital Agenda. Here are some suggestions that would help Europe re-take global leadership on openness, public sector reform, and economic growth: A strong European software strategy centred around open standards based interoperability by 2011. An ambitious new eCommission strategy for 2011-15 focused on migration to open standards by 2015. Aligning the IT portfolio across the Commission into one Digital Agenda DG by 2012. Focusing all best practice exchange in eGovernment on one social networking site, epractice.eu (full disclosure: I had a role in getting that site up and running) Prioritizing public sector needs in global standardization over European standardization by 2014.

  • Windows Phone 7 DatePicker gotcha

    - by David Turner
    The Silverlight Toolkit for Windows Phone adds some great extra controls for Windows Phone 7, one gotcha that I ran into was that the DatePicker Application Bar icons don’t show up unless you include them in your project. The problem is that your DatePicker ends up looking like this: Tim Heuer mentions this in his blog post about the Silverlight Toolkit for WP7, and as he says, it is documented in the source code: So the problem is that the icons can’t be referenced from the Silverlight Toolkit Assembly, and the solution is that you have to add them to you project in the ‘well known’ / pre-defined location of a top level folder in your project called Toolkit.Content, and you must make sure to mark the icons with a Build Action of  ‘Content’ otherwise it wont work: The result is that your DatePicker will now look like this:
