| # Bad-ish, we do not need Ubuntu for this, nor do we want latest if we are using in a build system, predictable is better | |
| FROM ubuntu:latest | |
| # Better, using a small image since our app has no dependency on Ubuntu | |
| FROM alpine:3.3 |

This document is research for the selection of a communication platform for robot-net.
The purpose of this component is to enable rapid, reliable, and elegant communication between the various nodes of the network, including controllers, sensors, and actuators (robot drivers). It will act as the core of robot-net to create a standardized infrastructure for robot control.
Requirements:
| -- A basic GDSII reader that reads from standard input and writes serialized | |
| -- text to standard output | |
| local gdsii = {} | |
| gdsii.types = { | |
| [0] = "HEADER", | |
| [1] = "BGNLIB", | |
| [2] = "LIBNAME", | |
| [3] = "UNITS", |

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
