I’ve ran into a little issue regarding functional dependencies and normalization. The thing is that I am not quite sure whether FD refers to values or the attribute as a whole. In other words, if I had a relation scheme (PKs have *) R {A, B, C, D, E} with the FD listed below, IRead more

Suppose I’d like to implement the templating pattern, but the only real differences between the subclasses are their choices of some invariant dependencies. Is there a drawback to preferring this style: public abstract class AbstractClass { private final DependencyA dependencyA; private final DependencyB dependencyB; public AbstractClass(final DependencyA dependencyA, final DependencyB dependencyB) { this.dependencyA = dependencyA;Read more

Our company has a few web applications which in turn depend on a very long chain of internally created and hosted npm packages each with their own dependencies (and so on). Whenever a bug is fixed or a feature is implemented in a low-level package the current process requires a developer to check in theirRead more

My poorly written tests suggests that the module works as intended. I fear this is to good to be true. I don’t known how to write unit tests for this. I’m new to writing tests and I think this module would be hard for a unit test master to test. #-*-coding:utf8;-*- #qpy:3 #qpy:console SINGLETONS =Read more

Problem: While adding the content I want to have fields that are hidden unless i choose something from another field.

I have a simple question about best practices in unit test verifications. Given this example: @Test public void methodUnderTest() { when(mockedDependency.someMethod()).thenReturn(someValue); int actual = classUnderTest.methodUnderTest(); assertEquals(5, actual); verify(mockedDependency).someMethod();//should I do this? } As you can see I’m checking that my mock is being used. Should I do this? With this verification if I change theRead more

Our project uses Gradle (whose dependency system is compatible with Maven IIUC). When depending on external projects, we try to depend on stable versions. Sometimes we have to depend on a development version. And sometimes we have to fork the repository of a dependency and depend on that (in general we try to upstream ourRead more

I am trying to remove old kernel images because I don’t have space on the server anymore, but whenever I try to remove the images using sudo apt-get remove xxx I get The following packages have unmet dependencies: linux-image-extra-3.13.0-135-generic : Depends: linux-image-3.13.0-135-generic but it is not going to be installed linux-image-generic : Depends: linux-image-3.13.0-135-generic butRead more
