RxJava provides canned (and cross-platform) scheduling, and easy composition of sequential asynchronous operations.
This should be more efficient than using a LocalBroad...
Animate the transition between fragments
...ally slides involve animating content to and from off-screen. As far as I know there aren't any transition properties that use relative values. However, this doesn't prevent you from writing them yourself. Remember that property animations simply require getter and setter methods on the objects you'...
How to name factory like methods?
...turns me an object that behaves as I expect'. I shouldn't always have to know whether it's a brand new object, in fact I might not care. So in suitable cases you might avoid a 'Create...' name, even if that's how you're implementing it right now.

Why can't I use float value as a template parameter?
...s are exact. Floating-point arithmetic is well-defined on every target I know of. Most floating-point operations produce floating-point results. I can appreciate the committee not wanting to force compiler implementors to implement the target's possibly-bizarre floating-point arithmetic, but I don...

What is the difference between map and flatMap and a good use case for each?
...ct
res0: Array[String] = Array("Roses are red", "Violets are blue")
Now, map transforms an RDD of length N into another RDD of length N.
For example, it maps from two lines into two line-lengths:
rdd.map(_.length).collect
res1: Array[Int] = Array(13, 16)
But flatMap (loosely speaking...
