Visualizing group sizes and inter-group flows

A few weeks ago, I came across the following graphics on Twitter: They depict voter share per party (including absentees, in grey) (top) and voter flows between different parties in the 2015 cantonal elections in Zurich. The graphics are produced by sotomo, a research company at the nexus...


Fabulous Finds I

→ The real reason American passenger trains are so bad “It’s not just that these services aren’t the best in the world and don’t deploy the most cutting-edge technology available. They are often truly abysmal, with travel times worse than what was possible 100 years...


Slide design and public speaking

I have a Slideshare account that I use to publish slides of presentations I’ve held (if it’s okay to publish them, which is the case only very occasionally). Sometimes Slideshare sends me e-mail news that I more often trash than skim. But yesterday a post with the...


Sunset on Mars

To all you Geohipsters out there

Have you heard of the Geohipster blog? It’s the self-described place for people who ‘grow their own organic vertices, use gluten-free topology or only geocode by hand, in small batches’. And I give at a big recommendation, put it into your feed reader. And relax, you don’t need to be a...


Geocoding Twitter users – The #SwissGIS map

Recently, I’ve been experimenting with some Twitter-oriented hacks together with my friend Tom. A very preliminary result of these activities is what I call the #SwissGIS map. Some, just a little, history: Over the last few years, I have been collecting Switzerland-based Twitter users that talk about topics...


Be nice to your sysadmin

Sysadmin Appreciation Day was exactly two months ago, but this gem shared by Bill Morris is too good to pass up on: (source) Then there’s of course also this classic by Randall Munroe: (source)
