Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

A friend of mine basically ask me this question, "How to chain two API calls in Rx?". At first I thought it would be a quick and easy code. And I was wrong, in the end I spent more time than I should, so I hope this post would help.

public interface WeatherApi {

    @GET("cities")
    Observable<List<City>> getCities(); 
    // Query params is omitted for simplicty, usually lat and lan
