Open Source and Open Science

My collection of articles on publicly available data sources, their access and interpretation, computational tools and publicly accessible scientific projects:

  • Open Data: Publicly available data sets from governments, universities, private and public organizations. Also contains examples of how to access, parse and visualize data.
  • Tools: Easy-to-use tools for data processing, visualization, simulation, and much more.
  • Open Science Projects: Open source projects or open access information.

Open Data

Publicly available data sources, ranging from NASA data sets of earth’s surface temperature to statistical data collected by EUROSTAT to data available through Google and others.

I’ll include some Python examples (mostly as a Jupyter notebook) demonstrating how to access the data (via HTML download, SQL query, web scrubbers…) and some quick post-processing.


Farewell to Cassini – The final plunge

A little blog post about the last days of Cassini before mission end and the collision with Saturn on Friday, September 15th 2017.

NASA Temperature Anomaly Data (GISTEMP)

Recently I encountered a very nice looking video illustrating climate change on LinkedIn. It’s purpose is to show the scale of global warming since 1900 based on a data set published by NASA (GISTEMP). The video looked very impressive until I looked closer. This post will dig into the background of the NASA data set, as well as the visualization methods used to produce the video.

EU Government Data – EU Open Data Portal

The EU Open Data Portal allows public access to open data produced by EU institutions and bodies. It contains scientific, environmental, social, financial, economical, trade and other data sets.

Open Source Tools

A collection of open source tools, code snippets and other useful additions to your virtual Swiss Army Knife.


Conversion between numerical base systems

The conversion of numbers between different bases has been something I had not encountered for a decade after leaving university. However I faced it in a recent job interview. While I did not have a confident answer in the interview, I spent some time to come up with one. So this post features a Jupyter-Notebook of my attempt to answer this question.

Render a galaxy with python and vispy

I was looking for a nice way to render a galaxy. Specifically I was looking for something I could easily do with python. I am using a number of 3D visualization packages on a daily basis, and my favourite packages suffer from the fact that they are not fully python 3...

Open Science

Open Science projects – larger-scale open source projects, research projects that make their data and publications available, and other related items.



OpenPNM – Pore Network Modeling for Porous Media

OpenPNM is an open source project to simulate two phase flow in porous media using a pore network approach.


OpenFCST – A collaborative fuel cell modeling platform

I used to work for a fuel cell company, and during my tenure we were very engaged in an Open Source framework for fuel cell simulations. I am still very much involved in the project and wanted to give it some well deserved air time.
