#Makers Academy week 1: Boris Bikes Challenge

London's Boris Bikes (well, 'Santander Cycles') are awesome. For a small fee, anyone can hire out a bike and ride it around London. Bikes are located at Docking Stations dotted throughout the city.

Setup

This project was completed using TDD and pairing. The daily changing pair programming nature of Maker's means that the project code base can change on a daily basis. Therefore, there are seperate (often ophan) branches for each session and these have not been merged due to differences in approach.

The project

Let's go back several years, to the days when there were no Boris Bikes. Imagine that you're a junior developer. Transport for London, the body responsible for delivery of a new bike system, come to you with a plan: a network of Docking Stations and bikes that anyone can use. They want you to build a program that will run all the Docking Stations, simulate all the Bikes, and emulate all the infrastructure (vans, repair staff, and so on) required to make their dream a reality. They call it - guess what? - 'Boris' Bikes, and they're offering a tasty sum of money.
