The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

Android Memory Management

Android has a unique memory management model. Below, are the notes taken while we try to understand it thoroughly.

Activity Manager

Overview

The ActivityManager, among other things, is responsible for making sure that apps that are most important to the user and/or essential remain active. It does this by dynamically assigning values that roughly indicate the app's importance. When memory gets low these values are used to find the apps that need to be "trimmed." The memory from these "trimmed" apps is freed, making more available for the more important apps.
