Observable React elements with RxJS

Note: if you want to skip history behind this, and just looking for final result see: rx-react-container

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.

1. The Layer Tree

Core Animation's original name is Layer Kit

Core Animation is a compositing engine; its job is to compose different pieces of visual content on the screen, and to do so as fast as possible. The content in question is divided into individual layers stored in a hierarchy known as the layer tree. This tree forms the underpinning for all of UIKit, and for everything that you see on the screen in an iOS application.

In UIView, tasks such as rendering, layout and animation are all managed by a Core Animation class called CALayer. The only major feature of UIView that isn’t handled by CALayer is user interaction.

There are four hierarchies, each performing a different role:

Algorithmic Trading (on a budget)

As a noob in investing, I kept hearing about record returns at top financial companies and hedge funds. So I figured, how hard can this be? Really?

Hence, I setup a personal challenge few years ago to not only learn but outperform top financial companies & hedge funds. I started working on algorithmic trading project. With an engineering background and a minor Economics, I had inadequate background, limited programming experience and funding; but loads of passion to accomplish this goal (a good enough combo).

Fast-forward 3 years later, I have created multiple trading algorithms in MATLAB, Python, AutoHotKey etc and managing 6 individual accounts (mine inclusive) with average annual returns of 15-20%; which is much better than average hedge fund, as measured by the Hedge Fund Research composite (HRFX) index. Not bad for a side project.
