...onoid" over sets (or in Haskell types). Okay, so free monads are the same idea. We take a functor, and give back a monad. In fact, since monads can be seen as monoids in the category of endofunctors, the definition of a list data [a] = [] | a : [a] looks a lot like the definition of free monad...

...ating traits that fulfill the capabilities required by an interface is the ideal use case. You should only use traits when multiple classes share the same functionality (likely dictated by the same interface). There's no sense in using a trait to provide functionality for a single class: that only ...

...lution #3 - Use the pointer-events property (demo) -- (Read more here) The idea here is to overlay an element over the native drop down arrow (to create our custom one) and then disallow pointer events on it. Advantage: It works well in WebKit and Gecko. It looks good too (no jutting out option elem...

...ce that the demos and code snippets here are meant to give you a different idea, to provide a modern approach to achieve the goal. Please mind the "Big Alert" section if you are going to use this approach in real world websites or applications. For further reading including browser support, these...

...oned, this almost always is no problem - and he also mentions it is a good idea to load the SharedPreferences once (maybe even in a Thread using a FutureTask) and hold it for any possible access to the single instance. – mreichelt Oct 22 '12 at 16:42 ...

... hopelessly trapped inside of extern "C" regions, but it isn't such a good idea from a cleanliness perspective. Now, specifically regarding your numbered questions: Regarding #1: __cplusplus will stay defined inside of extern "C" blocks. This doesn't matter, though, since the blocks should nest n...

...here in the call chain. Readability The other reason is readability. The ideal that code should aspire to is to be a human-readable document, where each line describes simply what it's doing. Take these two approaches: private int getInput() { int input; do { input = promptForInpu...

...ices a dip may map to one pixel while on others it may be nine pixels. The idea is that most screens will have the same number of “dips” to an inch of screen real estate. Developers can still give UI elements sizes in “pixels” in App Inventor, but realize those pixels are in fact dips. Ima...
