Use the curry function (from Prelude or Data.Tuple) to convert a function that takes tuples to a function that takes two arguments.
curry fst 1 2 -- computes 1
curry snd 1 2 -- computes 2
curry (uncurry f) -- computes the same as f
import Data.Tuple (swap)
curry swap 1 2 -- computes (2, 1...

public interface IVehicle
{
int MilesDriven { get; set; }
}
public static class Extensions

MSTest (the default testing framework) requires you to have your test classes decorated by a [TestClass] attribute, and the test methods with a [TestMethod] attribute, and to be public.
[TestClass]
public class FizzBuzzFixture
{
[TestMethod]
public void Test1()
{

When we use @SpringApplicationConfiguration it will use configuration from application.yml [properties] which in certain situation is not appropriate. So to override the properties we can use @TestPropertySource annotation.

While working on the development of an R package it is often necessary to install the latest version of the package. This can be achieved by first building a source distribution of the package (on the command line)
R CMD build my_package
and then installing it in R. Any running R sessions with p...
