Straße von Hormus: So legt der Krieg die Straße von Hormus lahm Seit Samstag droht der Iran damit, Schiffe anzugreifen, die die Straße von Hormus passieren. Sehen Sie hier, welche Folgen das für den Verkehr in der Meerenge hat.

I made an animated map of ship movements in the Straights of Hormuz using data from marinetraffic.com.

Ship track frames rendered using #ggplot, base map created using #gdal, video editing using #ffmpeg, video player written in #svelte.

Causal Inferences from Digital Behavioral Data - KZfSS Kölner Zeitschrift für Soziologie und Sozialpsychologie In recent years, digital behavioral data (DBD) have emerged as a powerful resource in social science research. Their ubiquity, granularity, complexity, and continuous collection provide new opportunit...

Joint paper with @floriankeusch.bsky.social out now: We discuss opportunities and challenges of causal inference from digital behavioral data, and methodological approaches for making these data fit for purpose:

Ich durfte in der @taz.de ein bisschen was zu Umfragen erzählen, und was soll ich sagen - Berichte über den Tod von Umfragen sind stark übertrieben...

Nochmal Glückwunsch, lieber Joff! Auf zu neuen Ufern! Füße aber besser nicht in den Neckar stecken.

Always a pleasure chatting with students who ask sharp questions 😊 Thanks to The Governance Post for having me - and yes, I stand by the autopilot line.

School council election. Also running: the class clown. Annoying to all, impossible to ignore.

Kid 1: “I’ll vote for him. He’s in my class.”
Kid 2: “Nice poster! He'll get my vote.”
Kid 1: “Also, he promised better school lunches.”

Flashback to last year’s Data4Good Hackathon challenges!

🏛 Municipal Innovation (with @bertelsmannst.bsky.social): > Participants tackled the Wegweiser Kommune dataset, using 400+ indicators to map out the future of German municipalities.

This is the week we’ve been waiting for:
The Data4Good Festival 2026!

We are excited to host 70+ students from across Europe at the Hertie School for a weekend of data-driven innovation and creativity in the heart of Berlin.

Thanks for referring to our research, @donmoyn.bsky.social!

A beautifully designed feature on a sad story. "As insects disappear, we’re losing the limbs and the twigs of the tree of life. We’re tearing it apart. And we’re leaving behind a very simplified and ugly tree."

Insect populations are declining at an unprecedented rate The most diverse group of organisms on the planet are in trouble and the consequences could be dire.

I can hardly think of a better example to motivate data science students by showing how their tools and investigative skills can be used to make real impact.

This is part one of a five-part investigation into detention camps in the Xinjiang region that won a Pulitzer Prize.

Blanked-Out Spots On China's Maps Helped Us Uncover Xinjiang's Camps China's Baidu blanked out parts of its mapping platform. We used those locations to find a network of buildings bearing the hallmarks of prisons and internment camps in Xinjiang. Here's how we did it.

The article makes the faultiness and consequences of algorithmic governance palpable — almost like scanning a restaurant bill. Awesome narration and visual communication.

A fascinating piece on Rotterdam’s welfare fraud algorithm, which shows how risk scoring and profiling slip into routine administration - aimed at people with the least room for error.
