At the Shibaura Institute of Technology I was given the opportunity to talk about GNU Octave.
In a previous blog post the setup of the Apache2 webserver including TLS was explained. Based upon that effort, this blog post deals with the setup of JupyterHub. The goal is to create an online development environment for fancy looking interactive GNU Octave notebooks. Those are a great tool for explaining mathematical code and software as they have builtin support for syntax-highlighting and, thanks to MathJax, mathematics.
