  • Help deciding on an area of study for a PhD [closed]

    - by ale
    I am going to start a PhD in about 1 year. My undergraduate degree is in computer science and my master's is in artificial intelligence. I want to get ideas about what's going to be hot in say 5 years i.e. what could I spend 3-4 years studying to potentially have expertise that will be applicable to industry and the computing world ? Impossible to answer factually but some ideas and thoughts would be great. I have narrowed my ideas down to AI (yes, even more AI) and information security. AI seems to becoming popular again but security is always a going to be useful. From a career point of view, if I were to stay working in software development then this might actually be the best move but I've always wanted to do a PhD! Many thanks :).

  • Entity Framework, Code First: where is the database?

    - by Marko Apfel
    With Entity Framework 5 in Visual Studio 2012 the code first feature could let you come to the question “Where is the automatically created database located?” I run in the question after changing the model which throws during the next run this error: “The model backing the 'MyContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).” Okay – clear I thought “delete the database”. But where is the database and what type is it??? In this constellation the frameworks generates a localDB. You could access this database via SQL Server Object Explorer. For the first time you have to add this localDB. The server name is “(localdb)\v11.0”: And so we could browse through the content of this database. It got the same name like the context class.

  • Moving from mock to real objects?

    - by jjchiw
    I'm like doing TDD so I started everything mocking objects, creating interface, stubbing, great. The design seems to work, now I'll implement the stuff, a lot of the code used in the stubs are going to be reused in my real implementation yay! Now should I duplicate the tests to use the real object implementation (but keeping the mocks object of the sensitive stuff like Database and "services" that are out of my context (http calls, etc...)) Or just change the mocks and stubs of the actual tests to use the real objects....... So the question is that, keep two tests or replace the stubs, mocks? And after that, I should keep designing with the mocks, stubs or just go with real objects? (Just making myself clear I'll keep the mock object of the sensitive stuff like database and services that are out of my context, in both situations.)

  • Could you give me an example of how to attach an object in Deleted state – I keep getting an exception [migrated]

    - by carewithl
    From MSDN : An object in the Deleted state can only be attached when the ObjectStateManager is already tracking the relationship instance. Could you give me an example of how to attach an object in the Deleted state. I tried the following and got "System.InvalidOperationException: The object being attached is in an added or deleted state. Relationships cannot be created for objects in this state". var contact = context.Contacts.First(); Console.WriteLine(contact.Addresses.Count()); // 2 var address = contact.Addresses.First(); context.Addresses.DeleteObject(address); contact.Addresses.Attach(address); // InvalidOperationException thank you

  • How do I make the 'Shut Down the Computer' window be monochrome ?

    - by Agmenor
    When I hit the power button of my computer, a window titled 'Shut Down the Computer' appears. It gives a few options, including shutting down or restarting. This window is different following the context I hit the power button : when logged in and seeing my desktop, it includes colourful icons (red for shutting down, for example). when I am not logged in yet, the icons are monochrome and a little bit more stylized. I clearly prefer the last type of icons : how do I set them as default whatever the context of use of the 'Shut Down the Computer' window ?

  • Why can't I get 100% code coverage on a method that calls a constructor of a generic type?

    - by Martin Watts
    Today I came across a wierd issue in a Visual Studio 2008 Code Coverage Analysis. Consider the following method:  private IController GetController<T>(IContext context) where T : IController, new() {     IController controller = new T();     controller.ListeningContext = context;     controller.Plugin = this;     return controller; } This method is called in a unit test as follows (MenuController has an empty constructor): controller = plugin.GetController<MenuController>(null);  After calling this method from a Unit Test, the following code coverage report is generated: As you can see, Code Coverage is only 85%. Looking up the code results in the following: Apparently, the call to the constructor of the generic type is considered only partly covered. WHY? Google didn't help. And MSDN didn't help at all, of course. Anybody who does know?
