How does it work? Kubernetes: Episode 5 – Master and Worker, at last!

Hey everybody, TL;DR I hacked something together in order to create a Kubernetes cluster on CoreOS (or Container Linux) using Vagrant and Ansible. If you keep reading, I'm going to talk to you about Kubernetes, etcd, CoreOS, flannel, Calico, Infrastructure as Code and Ansible testing strategies. It's gonna be super fun. The whole subject was way too long for a single article. Therefore, I’ve divided it into 5 parts. This is episode 5, regarding the actual installation and configuration of the Kubernetes Master and Worker…

Visualizing massive data streams: a public transport use case

Public transport companies release more data every day and some of them are even opening their information system up to real time streaming (Swiss transport, TPG in Geneva, RATP in Paris are a couple of local ones). Vast lands are unveiled for technical experimentations! Beside real time data, these companies also publish their full schedules. In Switzerland, it describes trains, buses, tramways, boats and even gondolas. In this post, we propose to walk through an application built to visualize, in fast motion, one day of activity,…
