In general you want to try and put things in onStart and onStop for logical start and stops.

Activity

onCreate

Dagger inject self into graph
setContentView(R.layout.xxx)
Butterknife.bind(this)
RxJava CompositeSubscription.add (if NON UI related work being done)
realm = Realm.getDefaultInstance();

Android Tools Attributes

Android has a dedicated XML namespace intended for tools to be able to record information in XML files, and have that information stripped when the application is packaged such that there is no runtime or download size penalty. The namespace URI is http://schemas.android.com/tools and is usually bound to the tools: prefix:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"

Applied Functional Programming with Scala - Notes

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

For-Comprehension Free Monads in Kotlin - Mini Howto

This GIST is an attempt to describe a repeatable, and automatable, process for building an embedded Domain Specific Language (DSL) with the help of a Free monad.
As material, i'll use Λrrow, the functional companion to Kotlin's Standard Library.

Disclaimer: This GIST assumes that you are roughly familiar with the concept of Free monad.
