I was interviewed for a podcast!
I talked with Wendo King'ang'i about (large) language models and opinion mining. It was recorded some time ago, so my affiliation is old, but the topic is still relevant, and I tried to make it as accessible as I could.

I think what annoys me most about the Microsoft products I am forced to work with is that they constantly try to gaslight me into thinking I had any control over what they do.

partycoloR is now on CRAN! Started as a simple idea 6 years ago, now it's a full-featured package. Extract party colors and logos from Wikipedia with one line of code. It's already powering ParlGov Dashboard.

3 rejections this year 💔. But (mostly) very helpful comments and the chance to further develop these projects (maybe for #ica27 in Glasgow?). (And still one accepted presentation 🥵)
It’s @icahdq.bsky.social notification day #ica26
Remember: we all get rejected, junior and senior scholars, it’s not personal. But it stings.
Congratulations to all who made it. Keep up the work, also if rejected 💪🏽

Talking to someone recently provided me with a new perspective on LLM usage: if you don't give a f*ck about the quality and accuracy of the output/product, using LLMs is great 😅

Not long ago I discussed with people what our red lines would be before not traveling to the US anymore. We landed on illegal occupation of another country, like Russia is attempting in Ukraine. We're there now.
Trump just announced that the US will now run the country for the foreseeable future.
With this precedent, can Putin do this against Zelenskyy? Or Xi against Lai Ching-te? (Pic posted by Trump on Truth Social of Maduro in handcuffs.) #PandoraBox

Reflections on the day 1 of the age ban: experts sidelined again, nuance ignored, and the debate drowned by low-effort vox pops. Policy built on vibes not evidence gets sold as "protecting kids" with all the spectacle of a state propaganda march, loud, choreographed, & divorced from substance.

Someone shared a dataset via sharepoint with me. It took me a week to find out it needs to be shared with my OneDrive account specifically and that I need to click a sync Button in a browser on a Windows machine with OneDrive installed to get the files. Every other way was broken or disabled. 🙇

Tiefgehende Vergleiche wie die Gleichsetzung der EU mit Nazi-Deutschland, der frei erfundene Genozid an weißen Menschen in Südafrika oder „Mechahitler“ – all das haben uns einige seit Monaten als enormen Nachteil auf #Bluesky beschrieben wollen... sie nannten es nur "Diversität der Meinungen".

X is free to appeal this decision in the European courts. A right it has because it *operates in the EU market.*
And of course if X doesn’t want to follow the EU’s laws at all, it’s free to withdraw from that market at any time.

What an absurd claim.
This is not a tax on Americans.
The EU creates laws to protect its citizens, in this case from fraud and deception. X operates in the EU market and must therefore follow its laws, including by reducing fraud and deception. X hasn’t done that. And so it’s being fined.
