I think the source sheds a little bit of light on this:

Assuming that you're talking about the language feature (e.g. interface keyword in Java), as opposed to the general computing term, the purpose of interfaces is polymorphism.

A tool such as interfaces can be abused for other purposes, for example:

• As a way of communicating commonality - this can backfire, because if polymorphism isn't the goal of the design, then the classes which declare implementing the interface are making an unnecessary commitment to implement it. That may cease to be relevant when the commonality is eventually broken, which can happen because the classes aren't used polymorphically.

• As a way of documenting the contract and allowing the class implementation to change - In Java, this is achieved with public/protected methods with Javadoc are the way to document the contract. Some languages don't even have that, and they still document contracts. Of course, this only works if the contract comes in form of function calls (as opposed to e.g. RESTful HTTP APIs), and it only works if you have a rule about what you document, e.g. package boundary; you wouldn't want to create an interface for every class, even if you document the contract for every class.

• To physically hide stuff from the consumer of your interface - this is also about documenting the contract, but if your class has data, or protected methods, and you want to prevent anything outside your package from inheriting, you can expose only an interface. But you can also use final.

Interfaces aren't designed to achieve multiple inheritance; they rather facilitate multiple inheritance only to the extent that is useful for polymorphism; it doesn't really allow you to inherit any fields, and until recently in Java with default methods (so, not by design), not even code.

You would see, in the wild, packages where only one class implements the interface. That doesn't render the interface useless; more implementations may come in the future, and in fact, the package might want to allow callers to offer their own implementation.

Okay, I've done some testing in Excel. I don't intend to accept this answer because I don't think it's a definitive answer to my question because:

• It's specific to Excel, so I don't know how these results will carry over to Access and other Office programs.
• It's just a test of a variety of cases. A definitive answer would be based on knowledge of the algorithms used to calculate IsEmpty(), VarType, and TypeName(), and to assign Empty.

With that disclaimer, here is the VBA function used for the test:

Unfortunately, you cannot chant the height of a dropdown list (while using ). It is confirmed here. you can build it yourself using divs & v-for (assuming you get the list from an outsource) and then you can style it as you wish. apologies for barring bad news.

Many matplotlib functions follow the color cycler to assign default colors, but that doesn't seem to apply here.

The following approach loops through the generated annotation texts (artists) and the clf tree structure to assign colors depending on the majority class and the impurity (gini). Note that we can't use alpha, as a transparent background would show parts of arrows that are usually hidden.

Is it beneficial to build multiple values from the same builder?

• If yes, use &mut self
• If no, use self

Consider std::thread::Builder which is a builder for std::thread::Thread. It uses Option fields internally to configure how to build the thread:

There is no one in the world that can give you an answer. The idea of all these restrictions is that we as developers need to optimize our applications. So if this is not possible for you it means most likely that you need to optimize the way you do your work. For this to happen you need to provide more info of what exactly events you are receiving, what is exactly your use case, etc.

As you can see there is info about exceptions for:

Your app receives a Bluetooth broadcast that requires the BLUETOOTH_CONNECT or BLUETOOTH_SCAN permissions.

But there is nothing in your question saying that your use case might relate to this.

Also, I don't understand how the app might be killed, but you keep working in the background.

Also if you want to constantly do something - why there is an event when you are in the background. Just when the user opens the app - start the service and keep it going.

You can also just "hack" it and ask the user to remove you from battery optimization.

The problem is that you are trying to pass datasets to the corels() function, however it wants you to pass file names. The Data Format section of the github for the corels software has details on how to format your data structures. These should then be saved in files and then passed to corels().

Each row in the data file should contain a rule name surrounded by curly braces, { and }, followed by a 0 or 1 to indicate whether that rule is true for that given row of data.

Here's a simple script to construct some:

Somehow, answering the questions parts in the opposite order felt more natural to me. :-)

Second, does auto-flattening allow any behavior that would be impossible if the left hand side were non-flattening?

It's relatively common to want to assign the first (or first few) items of a list into scalars and have the rest placed into an array. List assignment descending into iterables on the left is what makes this work:
