To illustrate how to use regr_slope(Y,X), I applied it to a real world problem. In Java, if you don't clean up memory properly, the garbage can get stuck and fill up the memory. You dump statistics every hour about memory utilization of different classes and load it into a postgres database for anal...

Lets first understand the problem, consider this figure- We want to calculate ϴ, where we know A, B & O. Now, if we want to get ϴ, we need to find out α and β first. For any straight line, we know- y = m * x + c Let- A = (ax, ay), B = (bx, by), and O = (ox, oy). So for the line OA- oy =...

When a Component is resolved from the Windsor container it must have a definition of the scope it is in. By scope meaning if and how it is reused and when to release the object for the Garbage Collector to destroy. This is the LifeStlye of the Component. The way to specify a LifeStyle is by registe...

By implementing your custom IScopeAccessor you can create different types of scopes. For the following example I have the two classes Foo and Bar in which Bar will be registered with a custom LifeStyle. Each have an Id to assist with testing public class Foo { public Guid FooId { get; } = G...
