• Amit Jasuja's Session at Gartner IAM with Ranjan Jain of Cisco

  - by Naresh Persaud

  If you did not get a chance to attend Amit Jasuja's session at Gartner IAM this week in Las Vegas, here is a summary of the session and a copy of the slides. The agenda featured an introduction by Ray Wagner, Managing VP at Gartner, followed by Amit discussing the trends in Identity and Access Management shaping Oracle's strategy. Today we are seeing the largest re-architecture in a decade. Every business from manufacturing to retail is transforming the way they do business. Manufacturing companies are becoming manufacturing services companies. Retail organizations are embracing social retail. Healthcare is being delivered on-line around the clock. Identity Management is at the center of the transformation. Whether you are Toyota embracing a social network for cars or launching the next Iphone, the Identity of the user provides context to enable the interaction and secure the experience. All of these require greater attention to the context of the user and externalizing applications for customers and employees.  Ranjan discussed how Cisco is transforming  by integrating 1800 applications to a single access management framework and consolidating 3M users across 4 data centers to support internal and external processes. David Lee demonstrated how to use Oracle Access Manager 11g R2 on a mobile application to sign-on across multiple applications while connecting mobile applications to a single access control policy.

• ODI 11g – Expert Accelerator for Model Creation

  - by David Allan

  Following on from my post earlier this morning on scripting model and topology creation tonight I thought I’d add a little UI to make those groovy functions a little more palatable. In OWB we have experts for capturing user input, with the groovy console we open up opportunities to build UI around the scripts in a very easy way – even I can do it;-) After a little googling around I found some useful posts on SwingBuilder, the most useful one that I used for the dialog below was this one here. This dialog captures user input for the technology and context for the model and logical schema etc to be created. You can see there are a variety of interesting controls, and its really easy to do. The dialog captures the users input, then when OK is pressed I call the functions from the earlier post to create the logical schema (plus all the other objects) and model. The image below shows what was created, you can see the model (with typo in name), the model is Oracle technology and references the logical schema ORACLE_SCOTT (that I named in dialog above), the logical schema is mapped via the GLOBAL context to the data server ORACLE_SCOTT_DEV (that I named in dialog above), and the physical schema used was just the user name that I connected with – so if you wanted a different user the schema name could be added to the dialog. In a nutshell, one dialog that encapsulates a simpler mechanism for creating a model. You can create your own scripts that use dialogs like this, capture input and process. You can find the groovy script for this is here odi_create_model.groovy, again I wrapped the user capture code in a groovy function and return the result in a variable and then simply call the createLogicalSchema and createModel functions from the previous posting. The script I supplied above has everything you will need. To execute use Tools->Groovy->Open Script and then execute the green play button on the toolbar. Have fun.

• Should interfaces inherit interfaces

  - by dreza

  Although this is a general question it is also specific to a problem I am currently experiencing. I currently have an interface specified in my solution called public interface IContextProvider { IDataContext { get; set; } IAreaContext { get; set; } } This interface is often used throughout the program and hence I have easy access to the objects I need. However at a fairly low level of a part of my program I need access to another class that will use IAreaContext and perform some operations off it. So I have created another factory interface to do this creation called: public interface IEventContextFactory { IEventContext CreateEventContext(int eventId); } I have a class that implements the IContextProvider and is injected using NinJect. The problem I have is that the area where I need to use this IEventContextFactory has access to the IContextProvider only and itself uses another class which will need this new interface. I don't want to have to instantiate this implementation of IEventContextFactory at the low level and would rather work with the IEventContextFactory interface throughout. However I also don't want to have to inject another parameter through the constructors just to have it passed through to the class that needs it i.e. // example of problem public class MyClass { public MyClass(IContextProvider context, IEventContextFactory event) { _context = context; _event = event; } public void DoSomething() { // the only place _event is used in the class is to pass it through var myClass = new MyChildClass(_event); myClass.PerformCalculation(); } } So my main question is, would this be acceptable or is it even common or good practice to do something like this (interface inherit another an interface): public interface IContextProvider : IEventContextFactory or should I consider better alternatives to achieving what I need. If I have not provided enough information to give suggestions let me know and I can provide more.

• Static objects and concurrency in a web application

  - by Ionut

  I'm developing small Java Web Applications on Tomcat server and I'm using MySQL as my database. Up until now I was using a connection singleton for accessing the database but I found out that this will ensure just on connection per Application and there will be problems if multiple users want to access the database in the same time. (They all have to make us of that single Connection object). I created a Connection Pool and I hope that this is the correct way of doing things. Furthermore it seems that I developed the bad habit of creating a lot of static object and static methods (mainly because I was under the wrong impression that every static object will be duplicated for every client which accesses my application). Because of this all the Service Classes ( classes used to handle database data) are static and distributed through a ServiceFactory: public class ServiceFactory { private static final String JDBC = "JDBC"; private static String impl; private static AccountService accountService; private static BoardService boardService; public static AccountService getAccountService(){ initConfig(); if (accountService == null){ if (impl.equalsIgnoreCase(JDBC)){ accountService = new JDBCAccountService(); } } return accountService; } public static BoardService getBoardService(){ initConfig(); if (boardService == null){ if (impl.equalsIgnoreCase(JDBC)){ boardService = new JDBCBoardService(); } } return boardService; } private static void initConfig(){ if (StringUtil.isEmpty(impl)){ impl = ConfigUtil.getProperty("service.implementation"); // If the config failed initialize with standard if (StringUtil.isEmpty(impl)){ impl = JDBC; } } } This was the factory class which, as you can see, allows just one Service to exist at any time. Now, is this a bad practice? What happens if let's say 1k users access AccountService simultaneously? I know that all this questions and bad practices come from a bad understanding of the static attribute in a web application and the way the server handles this attributes. Any help on this topic would be more than welcomed. Thank you for your time!

• Finetuning movement based on gradual rotation towards a target

  - by A.B.

  I have an object which moves towards a target destination by gradually adjusting its facing while moving forwards. If the target destination is in a "blind spot", then the object is incapable of reaching it. This problem is ilustrated in the picture below. When the arrow is ordered to move to point A, it will only end up circling around it (following the red circle) because it is not able to adjust its rotation quickly enough. I'm interested in a solution where the movement speed is multiplied by a number from 0.1 to 1 in proportion to necessity. The problem is, how do I calculate whether it is necessary in the first place? How do I calculate an appropriate multiplier that is neither too small nor too large? void moveToPoint(sf::Vector2f destination) { if (destination == position) return; auto movement_distance = distanceBetweenPoints(position, destination); desired_rotation = angleBetweenPoints(position, destination); /// Check whether rotation should be adjusted if (rotation != desired_rotation) { /// Check whether the object can achieve the desired rotation within the next adjustment of its rotation if (Radian::isWithinDistance(rotation, desired_rotation, rotation_speed)) { rotation = desired_rotation; } else { /// Determine whether to increment or decrement rotation in order to achieve desired rotation if (Radian::convert(desired_rotation - rotation) > 0) { /// Increment rotation rotation += rotation_speed; } else { /// Decrement rotation rotation -= rotation_speed; } } } if (movement_distance < movement_speed) { position = destination; } else { position.x = position.x + movement_speed*cos(rotation); position.y = position.y + movement_speed*sin(rotation); } updateGraphics(); }

• My New BDD Style

  - by Liam McLennan

  I have made a change to my code-based BDD style. I start with a scenario such as: Pre-Editing * Given I am a book editor * And some chapters are locked and some are not * When I view the list of chapters for editing * Then I should see some chapters are editable and are not locked * And I should see some chapters are not editable and are locked and I implement it using a modified SpecUnit base class as: [Concern("Chapter Editing")] public class when_pre_editing_a_chapter : BaseSpec { private User i; // other context variables protected override void Given() { i_am_a_book_editor(); some_chapters_are_locked_and_some_are_not(); } protected override void Do() { i_view_the_list_of_chapters_for_editing(); } private void i_am_a_book_editor() { i = new UserBuilder().WithUsername("me").WithRole(UserRole.BookEditor).Build(); } private void some_chapters_are_locked_and_some_are_not() { } private void i_view_the_list_of_chapters_for_editing() { } [Observation] public void should_see_some_chapters_are_editable_and_are_not_locked() { } [Observation] public void should_see_some_chapters_are_not_editable_and_are_locked() { } } and the output from the specunit report tool is: Chapter Editing specifications    1 context, 2 specifications Chapter Editing, when pre editing a chapter    2 specifications should see some chapters are editable and are not locked should see some chapters are not editable and are locked The intent is to provide a clear mapping from story –> scenarios –> bdd tests.

• Security exception in Twitterizer

  - by Raghu

  Hi, We are using Twitterizer for Twitter integration to get the Tweets details. When making call to the method OAuthUtility.GetRequestToken, following exception is coming. System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. When the application is hosted on IIS 5, the application works fine and the above error is coming only when the application is hosted in IIS 7 on Windows 2008 R2. and the method OAuthUtility.GetRequestToken throws above exception. It seems the issue is something with code access security. Please suggest what kind of permissions should be given to fix the security exception. The application has the Full Trust and I have even tried by registering the Twitterizer DLL in GAC and still the same error is coming. I am not sure what makes the difference between IIS 5 and IIS 7 with regards to code access security to cause that exception. Following is the stack track of the exception. [SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.] System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) +0 System.Security.CodeAccessPermission.Demand() +54 Twitterizer.OAuthUtility.ExecuteRequest(String baseUrl, Dictionary`2 parameters, HTTPVerb verb, String consumerKey, String consumerSecret, String token, String tokenSecret, WebProxy proxy) +224 Twitterizer.OAuthUtility.GetRequestToken(String consumerKey, String consumerSecret, String callbackAddress, WebProxy proxy) +238 Twitter._Default.btnSubmit_Click(Object sender, EventArgs e) +94 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +115 System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +140 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +29 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +11045655 System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +11045194 System.Web.UI.Page.ProcessRequest() +91 System.Web.UI.Page.ProcessRequest(HttpContext context) +240 ASP.authorization_aspx.ProcessRequest(HttpContext context) in c:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files\twitter\c2fd5853\dcb96ae9\App_Web_y_ada-ix.0.cs:0 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +599 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +171 Any help would be greatly appreciated.

• Juju Zookeeper & Provisioning Agent Not Deployed

  - by Keith Tobin

  I am using juju with the openstack provider, i expected that when i bootstrap that zookeeper and provisioning agent would get deployed on the bootstrap vm in openstack. This dose not seem to be the case. the bootstrap vm gets deployed but it seems that nothing gets deployed to the VM. See logs below, I may be missing something, also how is it possible to log on the bootstrap vm. Could I manual deploy, if so what do I need to do.

• Metro: Understanding the default.js File

  - by Stephen.Walther

  The goal of this blog entry is to describe — in painful detail — the contents of the default.js file in a Metro style application written with JavaScript. When you use Visual Studio to create a new Metro application then you get a default.js file automatically. The file is located in a folder named \js\default.js. The default.js file kicks off all of your custom JavaScript code. It is the main entry point to a Metro application. The default contents of the default.js file are included below: // For an introduction to the Blank template, see the following documentation: // http://go.microsoft.com/fwlink/?LinkId=232509 (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) { // TODO: This application has been newly launched. Initialize // your application here. } else { // TODO: This application has been reactivated from suspension. // Restore application state here. } WinJS.UI.processAll(); } }; app.oncheckpoint = function (eventObject) { // TODO: This application is about to be suspended. Save any state // that needs to persist across suspensions here. You might use the // WinJS.Application.sessionState object, which is automatically // saved and restored across suspension. If you need to complete an // asynchronous operation before your application is suspended, call // eventObject.setPromise(). }; app.start(); })(); There are several mysterious things happening in this file. The purpose of this blog entry is to dispel this mystery. Understanding the Module Pattern The first thing that you should notice about the default.js file is that the entire contents of this file are enclosed within a self-executing JavaScript function: (function () { ... })(); Metro applications written with JavaScript use something called the module pattern. The module pattern is a common pattern used in JavaScript applications to create private variables, objects, and methods. Anything that you create within the module is encapsulated within the module. Enclosing all of your custom code within a module prevents you from stomping on code from other libraries accidently. Your application might reference several JavaScript libraries and the JavaScript libraries might have variables, objects, or methods with the same names. By encapsulating your code in a module, you avoid overwriting variables, objects, or methods in the other libraries accidently. Enabling Strict Mode with “use strict” The first statement within the default.js module enables JavaScript strict mode: 'use strict'; Strict mode is a new feature of ECMAScript 5 (the latest standard for JavaScript) which enables you to make JavaScript more strict. For example, when strict mode is enabled, you cannot declare variables without using the var keyword. The following statement would result in an exception: hello = "world!"; When strict mode is enabled, this statement throws a ReferenceError. When strict mode is not enabled, a global variable is created which, most likely, is not what you want to happen. I’d rather get the exception instead of the unwanted global variable. The full specification for strict mode is contained in the ECMAScript 5 specification (look at Annex C): http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf Aliasing the WinJS.Application Object The next line of code in the default.js file is used to alias the WinJS.Application object: var app = WinJS.Application; This line of code enables you to use a short-hand syntax when referring to the WinJS.Application object: for example,  app.onactivated instead of WinJS.Application.onactivated. The WinJS.Application object  represents your running Metro application. Handling Application Events The default.js file contains an event handler for the WinJS.Application activated event: app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) { // TODO: This application has been newly launched. Initialize // your application here. } else { // TODO: This application has been reactivated from suspension. // Restore application state here. } WinJS.UI.processAll(); } }; This WinJS.Application class supports the following events: · loaded – Happens after browser DOMContentLoaded event. After this event, the DOM is ready and you can access elements in a page. This event is raised before external images have been loaded. · activated – Triggered by the Windows.UI.WebUI.WebUIApplication activated event. After this event, the WinRT is ready. · ready – Happens after both loaded and activated events. · unloaded – Happens before application is unloaded. The following default.js file has been modified to capture each of these events and write a message to the Visual Studio JavaScript Console window: (function () { "use strict"; var app = WinJS.Application; WinJS.Application.onloaded = function (e) { console.log("Loaded"); }; WinJS.Application.onactivated = function (e) { console.log("Activated"); }; WinJS.Application.onready = function (e) { console.log("Ready"); } WinJS.Application.onunload = function (e) { console.log("Unload"); } app.start(); })(); When you execute the code above, a message is written to the Visual Studio JavaScript Console window when each event occurs with the exception of the Unload event (presumably because the console is not attached when that event is raised).   Handling Different Activation Contexts The code for the activated handler in the default.js file looks like this: app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) { // TODO: This application has been newly launched. Initialize // your application here. } else { // TODO: This application has been reactivated from suspension. // Restore application state here. } WinJS.UI.processAll(); } }; Notice that the code contains a conditional which checks the Kind of the event (the value of e.detail.kind). The startup code is executed only when the activated event is triggered by a Launch event, The ActivationKind enumeration has the following values: · launch · search · shareTarget · file · protocol · fileOpenPicker · fileSavePicker · cacheFileUpdater · contactPicker · device · printTaskSettings · cameraSettings Metro style applications can be activated in different contexts. For example, a camera application can be activated when modifying camera settings. In that case, the ActivationKind would be CameraSettings. Because we want to execute our JavaScript code when our application first launches, we verify that the kind of the activation event is an ActivationKind.Launch event. There is a second conditional within the activated event handler which checks whether an application is being newly launched or whether the application is being resumed from a suspended state. When running a Metro application with Visual Studio, you can use Visual Studio to simulate different application execution states by taking advantage of the Debug toolbar and the new Debug Location toolbar.  Handling the checkpoint Event The default.js file also includes an event handler for the WinJS.Application checkpoint event: app.oncheckpoint = function (eventObject) { // TODO: This application is about to be suspended. Save any state // that needs to persist across suspensions here. You might use the // WinJS.Application.sessionState object, which is automatically // saved and restored across suspension. If you need to complete an // asynchronous operation before your application is suspended, call // eventObject.setPromise(). }; The checkpoint event is raised when your Metro application goes into a suspended state. The idea is that you can save your application data when your application is suspended and reload your application data when your application resumes. Starting the Application The final statement in the default.js file is the statement that gets everything going: app.start(); Events are queued up in a JavaScript array named eventQueue . Until you call the start() method, the events in the queue are not processed. If you don’t call the start() method then the Loaded, Activated, Ready, and Unloaded events are never raised. Summary The goal of this blog entry was to describe the contents of the default.js file which is the JavaScript file which you use to kick off your custom code in a Windows Metro style application written with JavaScript. In this blog entry, I discussed the module pattern, JavaScript strict mode, handling first chance exceptions, WinJS Application events, and activation contexts.

• Mapping between 4+1 architectural view model & UML

  - by Sadeq Dousti

  I'm a bit confused about how the 4+1 architectural view model maps to UML. Wikipedia gives the following mapping: Logical view: Class diagram, Communication diagram, Sequence diagram. Development view: Component diagram, Package diagram Process view: Activity diagram Physical view: Deployment diagram Scenarios: Use-case diagram The paper Role of UML Sequence Diagram Constructs in Object Lifecycle Concept gives the following mapping: Logical view (class diagram (CD), object diagram (OD), sequence diagram (SD), collaboration diagram (COD), state chart diagram (SCD), activity diagram (AD)) Development view (package diagram, component diagram), Process view (use case diagram, CD, OD, SD, COD, SCD, AD), Physical view (deployment diagram), and Use case view (use case diagram, OD, SD, COD, SCD, AD) which combines the four mentioned above. The web page UML 4+1 View Materials presents the following mapping: Finally, the white paper Applying 4+1 View Architecture with UML 2 gives yet another mapping: Logical view class diagrams, object diagrams, state charts, and composite structures Process view sequence diagrams, communication diagrams, activity diagrams, timing diagrams, interaction overview diagrams Development view component diagrams Physical view deployment diagram Use case view use case diagram, activity diagrams I'm sure further search will reveal other mappings as well. While various people usually have different perspectives, I don't see why this is the case here. Specially, each UML diagram describes the system from a particular aspect. So, for instance, why the "sequence diagram" is considered as describing the "logical view" of the system by one author, while another author considers it as describing the "process view"? Could you please help me clarify the confusion?

• PHP Aspect Oriented Design

  - by Devin Dixon

  This is a continuation of this Code Review question. What was taken away from that post, and other aspect oriented design is it is hard to debug. To counter that, I implemented the ability to turn tracing of the design patterns on. Turning trace on works like: //This can be added anywhere in the code Run::setAdapterTrace(true); Run::setFilterTrace(true); Run::setObserverTrace(true); //Execute the functon echo Run::goForARun(8); In the actual log with the trace turned on, it outputs like so: adapter 2012-02-12 21:46:19 {"type":"closure","object":"static","call_class":"\/public_html\/examples\/design\/ClosureDesigns.php","class":"Run","method":"goForARun","call_method":"goForARun","trace":"Run::goForARun","start_line":68,"end_line":70} filter 2012-02-12 22:05:15 {"type":"closure","event":"return","object":"static","class":"run_filter","method":"\/home\/prodigyview\/public_html\/examples\/design\/ClosureDesigns.php","trace":"Run::goForARun","start_line":51,"end_line":58} observer 2012-02-12 22:05:15 {"type":"closure","object":"static","class":"run_observer","method":"\/home\/prodigyview\/public_html\/public\/examples\/design\/ClosureDesigns.php","trace":"Run::goForARun","start_line":61,"end_line":63} When the information is broken down, the data translates to: Called by an adapter or filter or observer The function called was a closure The location of the closure Class:method the adapter was implemented on The Trace of where the method was called from Start Line and End Line The code has been proven to work in production environments and features various examples of to implement, so the proof of concept is there. It is not DI and accomplishes things that DI cannot. I wouldn't call the code boilerplate but I would call it bloated. In summary, the weaknesses are bloated code and a learning curve in exchange for aspect oriented functionality. Beyond the normal fear of something new and different, what are other weakness in this implementation of aspect oriented design, if any? PS: More examples of AOP here: https://github.com/ProdigyView/ProdigyView/tree/master/examples/design

• Should interfaces extend (and in doing so inherit methods of) other interfaces

  - by dreza

  Although this is a general question it is also specific to a problem I am currently experiencing. I currently have an interface specified in my solution called public interface IContextProvider { IDataContext { get; set; } IAreaContext { get; set; } } This interface is often used throughout the program and hence I have easy access to the objects I need. However at a fairly low level of a part of my program I need access to another class that will use IAreaContext and perform some operations off it. So I have created another factory interface to do this creation called: public interface IEventContextFactory { IEventContext CreateEventContext(int eventId); } I have a class that implements the IContextProvider and is injected using NinJect. The problem I have is that the area where I need to use this IEventContextFactory has access to the IContextProvider only and itself uses another class which will need this new interface. I don't want to have to instantiate this implementation of IEventContextFactory at the low level and would rather work with the IEventContextFactory interface throughout. However I also don't want to have to inject another parameter through the constructors just to have it passed through to the class that needs it i.e. // example of problem public class MyClass { public MyClass(IContextProvider context, IEventContextFactory event) { _context = context; _event = event; } public void DoSomething() { // the only place _event is used in the class is to pass it through var myClass = new MyChildClass(_event); myClass.PerformCalculation(); } } So my main question is, would this be acceptable or is it even common or good practice to do something like this (interface extend another an interface): public interface IContextProvider : IEventContextFactory or should I consider better alternatives to achieving what I need. If I have not provided enough information to give suggestions let me know and I can provide more.

• Operation MVC

  - by Ken Lovely, MCSE, MCDBA, MCTS

  It was time to create a new site. I figured VS 2010 is out so I should write it using MVC and Entity Framework. I have been very happy with MVC. My boss has had me making an administration web site in MVC2 but using 2008. I think one of the greatest features of MVC is you get to work with root of the app. It is kind of like being an iron worker; you get to work with the metal, mold it from scratch. Getting my articles out of my database and onto web pages was by far easier with MVC than it was with regular ASP.NET. This code is what I use to post the article to that page. It's pretty straightforward. The link in the menu is passes the id which is simply the url to the page. It looks for that url in the database and returns the rest of the article.   DataResults dr = new DataResults(); string title = string.Empty; string article = string.Empty; foreach (var D in dr.ReturnArticle(ViewData["PageName"].ToString())) { title = D.Title; article = D.Article; } public   List<CurrentArticle> ReturnArticle(string id) { var resultlist = new List<CurrentArticle>(); DBDataContext context = new DBDataContext(); var results = from D in context.MyContents where D.MVCURL.Contains(id) select D;foreach (var result in results) { CurrentArticle ca = new CurrentArticle(); ca.Title = result.Title; ca.Article = result.Article; ca.Summary = result.Summary; resultlist.Add(ca); } return resultlist;}

• Ambiguous in the namespace problem

  - by Agha Usman Ahmed

  From the last few days, I was ignoring an error that keep coming at the compile time. I spent some two hours on it before but didn’t get it work. The error is quit confusing and of course difficult to manage. 'ApplicationSettingsBase' is ambiguous in the namespace 'System.Configuration' 'MailMessage' is ambiguous in the namespace 'System.Net.Mail' And there are couple of other similar errors that is pointing to some ambiguous references in my project.  The confusing part is that the MailMessage object throws similar error when you are importing the old and new email namespace. For example, Imports System.Web.Mail Imports System.Net.Mail So if you are only encountering ambiguous problem in MailMessage object. It is more possible that you have define both the namespaces in your code behind which is actually confusing the compiler about your referencing object. The quick solve for this problem is that remove Imports System.Web.Mail and it should work smooth. But with me, I never used the old asp.net mail namespace in my project. Then I start looking at my references and luckily I found the problem there. Follow the steps below to investigate the issue 1. Go to your project 2. Then references 3. Right click on “System” and see properties. it should point to the following path x:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll Where x is name of your operating system directory. This was the problem with my project. I had my operating system install on “D” drive and some how it is pointing to “C” drive which is the root cause of this problem. After that I verify all my references and found 5 –6 assemblies that are pointing to wrong path and get it worked. Also note, the problem can occur in any type of project either it is website , web application etc.

• JavaScript objects and Crockford's The Good Parts

  - by Jonathan

  I've been thinking quite a bit about how to do OOP in JS, especially when it comes to encapsulation and inheritance, recently. According to Crockford, classical is harmful because of new(), and both prototypal and classical are limited because their use of constructor.prototype means you can't use closures for encapsulation. Recently, I've considered the following couple of points about encapsulation: Encapsulation kills performance. It makes you add functions to EACH member object rather than to the prototype, because each object's methods have different closures (each object has different private members). Encapsulation forces the ugly "var that = this" workaround, to get private helper functions to have access to the instance they're attached to. Either that or make sure you call them with privateFunction.apply(this) everytime. Are there workarounds for either of two issues I mentioned? if not, do you still consider encapsulation to be worth it? Sidenote: The functional pattern Crockford describes doesn't even let you add public methods that only touch public members, since it completely forgoes the use of new() and constructor.prototype. Wouldn't a hybrid approach where you use classical inheritance and new(), but also call Super.apply(this, arguments) to initialize private members and privileged methods, be superior?

As an industry, we’ve spent many years analyzing all the data that’s been collected. Yes, that data has been invaluable in helping us make better decisions like where to open new stores, how to assort those stores, and how to price our products. But the recent advances in technology are now making it possible to analyze and deliver that data very quickly… fast enough to impact a potential sale in near real-time. Let me give you two examples. Salesmen in car dealerships get pretty good at sizing people up. When a potential customer walks in the door, it doesn’t take long for the salesman to figure out the revenue at stake. Is this person a real buyer, or just looking for a fun test drive? Will this person buy today or three months from now? Will this person opt for the expensive packages, or go bare bones? While the salesman certainly asks some leading questions, much of information is discerned through body language. But body language doesn’t translate very well over the web. Eloqua, which was acquired by Oracle earlier this year, reads internet body language. By tracking the behavior of the people visiting your web site, Eloqua categorizes visitors based on their propensity to buy. While Eloqua’s roots have been in B2B, we’ve been looking at leveraging the technology with ATG to target B2C. Knowing what sites were previously visited, how often the customer has been to your site recently, and how long they’ve spent searching can help understand where the customer is in their purchase journey. And knowing that bit of information may be enough to help close the deal with a real-time offer, follow-up email, or online customer service pop-up. This isn’t so different from the days gone by when the clerk behind the counter of the corner store noticed you were lingering in a particular aisle, so he walked over to help you compare two products and close the sale. You appreciated the personalized service, and he knew the value of the long-term relationship. Move that same concept into the digital world and you have Oracle’s CX Suite, a cloud-based offering of end-to-end customer experience tools, assembled primarily from acquisitions. Those tools are Oracle Marketing (Eloqua), Oracle Commerce (ATG, Endeca), Oracle Sales (Oracle CRM On Demand), Oracle Service (RightNow), Oracle Social (Collective Intellect, Vitrue, Involver), and Oracle Content (Fatwire). We are providing the glue that binds the CIO and CMO together to unleash synergies that drive the top-line higher, and by virtue of the cloud-approach, keep costs at bay. My second example of real-time marketing takes place in the store but leverages the concepts of Web marketing. In 1962 the decline of personalized service in retail began. Anyone know the significance of that year? That’s when Target, K-Mart, and Walmart each opened their first stores, and over the succeeding years the industry chose scale over personal service. No longer were you known as “Jane with the snotty kid so make sure we check her out fast,” but you suddenly became “time-starved female age 20-30 with kids.” I’m not saying that was a bad thing – it was the right thing for our industry at the time, and it enabled a huge amount of growth, cheaper prices, and more variety of products. But scale alone is no longer good enough. Today’s sophisticated consumer demands scale, experience, and personal attention. To some extent we’ve delivered that on websites via the magic of cookies, your willingness to log in, and sophisticated data analytics. What store manager wouldn’t love a report detailing all the visitors to his store, where they came from, and which products that examined? People trackers are getting more sophisticated, incorporating infrared, video analytics, and even face recognition. (Next time you walk in front on a mannequin, don’t be surprised if it’s looking back.) But the ultimate marketing conduit is the mobile phone. Since each mobile phone emits a unique number on WiFi networks, it becomes the cookie of the physical world. Assuming congress keeps privacy safeguards reasonable, we’ll have a win-win situation for both retailers and consumers. Retailers get to know more about the consumer’s purchase journey, and consumers get higher levels of service with the retailer. When I call my bank, a couple things happen before the call is connected. A reverse look-up on my phone number identifies me so my accounts can be retrieved from Siebel CRM. Then the system anticipates why I’m calling based on recent transactions. In this example, it sees that I was just charged a foreign currency fee, so it assumes that’s the reason I’m calling. It puts all the relevant information on the customer service rep’s screen as it connects the call. When I complain about the fee, the rep immediately sees I’m a great customer and I travel lots, so she suggests switching me to their traveler’s card that doesn’t have foreign transaction fees. That technology is powered by a product called Oracle Real-Time Decisions, a rules engine built to execute very quickly, basically in the time it takes the phone to ring once. So let’s combine the power of that product with our new-found mobile cookie and provide contextual customer interactions in real-time. Our first opportunity comes when a customer crosses a pre-defined geo-fence, typically a boundary around the store. Context is the key to our interaction: that’s the customer (known or anonymous), the time of day and day of week, and location. Thomas near the downtown store on a Wednesday at noon means he’s heading to lunch. If he were near the mall location on a Saturday morning, that’s a completely different context. But on his way to lunch, we’ll let Thomas know that we’ve got a new shipment of ASICS running shoes on display with a simple text message. We used the context to look-up Thomas’ past purchases and understood he was an avid runner. We used the fact that this was lunchtime to select the type of message, in this case an informational message instead of an offer. Thomas enters the store, phone in hand, and walks to the shoe department. He scans one of the new ASICS shoes using the convenient QR Codes we provided on the shelf-tags, but then he starts scanning low-end Nikes. Each scan is another opportunity to both learn from Thomas and potentially interact via another message. Since he historically buys low-end Nikes and keeps scanning them, he’s likely falling back into his old ways. Our marketing rules are currently set to move loyal customer to higher margin products. We could have set the dials to increase visit frequency, move overstocked items, increase basket size, or many other settings, but today we are trying to move Thomas to higher-margin products. We send Thomas another text message, this time it’s a personalized offer for 10% off ASICS good for 24 hours. Offering him a discount on Nikes would be throwing margin away since he buys those anyway. We are using our marketing dollars to change behavior that increases the long-term value of Thomas. He decides to buy the ASICS and scans the discount code on his phone at checkout. Checkout is yet another opportunity to interact with Thomas, so the transaction is sent back to Oracle RTD for evaluation. Since Thomas didn’t buy anything with the shoes, we’ll print a bounce-back coupon on the receipt offering 30% off ASICS socks if he returns within seven days. We have successfully started moving Thomas from low-margin to high-margin products. In both of these marketing scenarios, we are able to leverage data in near real-time to decide how best to interact with the customer and lead to an increase in the lifetime value of the customer. The key here is acting at the moment the customer shows interest using the context of the situation. We aren’t pushing random products at haphazard times. We are tailoring the marketing to be very specific to this customer, and it’s the technology that allows this to happen in near real-time. Conclusion As we enable more right-time integrations and interactions, retailers will begin to offer increased service to their customers. Localized and personalized service at scale will drive loyalty and lead to meaningful revenue growth for the retailers that execute well. Our industry needs to support Commerce Anywhere…and commerce anytime as well.

• Interpolate air drag for my game?

  - by Valentin Krummenacher

  So I have a little game which works with small steps, however those steps vary in time, so for example I sometimes have 10 Steps/second and then I have 20 Steps/second. This changes automatically depending on how many steps the user's computer can take. To avoid inaccurate positioning of the game's player object I use y=v0*dt+g*dt^2/2 to determine my objects y-position, where dt is the time since the last step, v0 is the velocity of my object in the beginning of my step and g is the gravity. To calculate the velocity in the end of a step I use v=v0+g*dt what also gives me correct results, independent of whether I use 2 steps with a dt of for example 20ms or one step with a dt of 40ms. Now I would like to introduce air drag. For simplicity's sake I use a=k*v^2 where a is the air drag's acceleration (I am aware that it would usually result in a force, but since I assume 1kg for my object's mass the force is the same as the resulting acceleration), k is a constant (in this case I'm using 0.001) and v is the speed. Now in an infinitely small time interval a is k multiplied by the velocity in this small time interval powered by 2. The problem is that v in the next time interval would depend on the drag of the last which again depends on the v of the last interval and so on... In other words: If I use a=k*v^2 I get different results for my position/velocity when I use 2 steps of 20ms than when I use one step of 40ms. I used to have this problem for my position too, but adding +g*dt^2/2 to the formula for my position fixed the problem since it takes into account that the position depends on the velocity which changes slightly in every infinitely small time interval. Does something like that exist for air drag too? And no, I dont mean anything like Adding air drag to a golf ball trajectory equation or similar, for that kind of method only gives correct results when all my steps are the same. (I hope you can understand my intermediate english, it's not my main language so I would like to say sorry for all the silly mistakes I might have made in my question)

• Closed-loop Recommendation Engines: Analyst Insight report on Oracle Real-Time Decisions (RTD)

  - by Mike.Hallett(at)Oracle-BI&EPM

  In November 2011, Helena Schwenk of MWD Advisors, published her analysis on Oracle Real-Time Decisions.  She summarizes as follows: "In contrast to other popular approaches to implementing predictive analytics, RTD focuses on learning from each interaction and using these insights to adjust what is presented, offered or displayed to a customer. Likewise its capabilities for optimising decisions within the context of specific business goals and a report-driven framework for assessing the performance of models and decisions make it a strong contender for organisations that want to continuously improve decision making as part of a customer experience marketing, e-commerce optimisation and operational process efficiency initiative." This is an outstanding report to share with a prospect or client as it goes into great detail about the product and its capabilities.  It also highlights the differences in Oracle's Real-Time Decisions product vs. other closed loop recommendation engines. I encourage you to share this report with your clients and prospects. It can be downloaded directly from here - MWD Advisors Vendor Profile: Oracle Real-Time Decisions. (expires in November 2012) Highlights: "At the core of RTD lies a learning engine that combines business rules and adaptive predictive models to deliver recommendations to operational systems while simultaneously learning from experiences." "While closed-loop recommendation engines are becoming more prevalent... there are a number of features that distinguish RTD: It makes its decisions in the context of the business objectives, such as maximising customer revenue or reducing service costs Its support for operational integration offers organisations some flexibility in how they implement the offering."
