Testing modules in rspec
...rom its host (do we say "host"?) class - If I don't already inherit from a base class or can't inject the new functionality into the inheritance tree then I think I'd be trying to minimise any such expectations that a module might have. My concern being that my design would start to develop some are...
Get the current first responder without using a private API
...rote a category on UIView, which I call on the UIWindow.
The following is based on that and should return the first responder.
@implementation UIView (FindFirstResponder)
- (id)findFirstResponder
{
if (self.isFirstResponder) {
return self;
}
for (UIView *subView in self...
__lt__ instead of __cmp__
...ust __lt__ and multiply inherit from ComparableMixin (after whatever other bases it needs, if any). A class decorator would be quite similar, just inserting similar functions as attributes of the new class it's decorating (the result might be microscopically faster at runtime, at equally minute cost...

What are the differences between Abstract Factory and Factory design patterns?
...
Abstract factory creates a base class with abstract methods defining methods for the objects that should be created. Each factory class which derives the base class can create their own implementation of each object type.

What's the “big idea” behind compojure routes?
...e factored into a collection of well-defined pieces; these are normally a "base" handler function and a collection of middleware functions wrapping it. Compojure's purpose is to simplify the generation of the base handler function.
How?
Compojure is built around the notion of "routes". These are...
How do I use reflection to invoke a private method?
...a group of private methods in my class, and I need to call one dynamically based on an input value. Both the invoking code and the target methods are in the same instance. The code looks like this:
...
List goals/targets in GNU make that contain variables in their definition
...
Can you parse the output from make -pn (i.e. make --print-data-base --dry-run)? It prints out all the variables, rules, implicit rules and which commands will be run in laborious detail.

Where should @Service annotation be kept? Interface or Implementation?
... Spring Beans, and
have an injection point that use the interface for type based injection,
then you will get and NoUniqueBeanDefinitionException

Why would I use Scala/Lift over Java/Spring? [closed]
... JPA).
Of course, Spring supports a panoply of standard and/or mature database technologies. The operative word there is "supports". Theoretically, you can use any Java ORM with Lift, since you can call arbitrary Java code from Scala. But Lift only really supports Mapper and (to a much lesser e...
