So unless representatives from both parties find a common language to talk about the economy again, it will be impossible to prevent future government shutdowns and ugly budget processes. And there are some faint indications that the same fate awaits other issues, too.

The paper effectively confirms some hypotheses observers already had regarding the budget process: the results show that the slow and painful process of getting to a budget is indeed prone to fail: representatives especially in the House no longer agree about where the budget should go.

When you do it like this, you neither focus on affective nor ideological polarization (disagreement on the same issues), but rather ask: Do they even talk the same language? It turns out: they don't. Especially since the Trump administrations. This effect is extra pronounced in economic discourse.

I collected a large corpus of Congressional Speeches between 1873 and 2025 (ca. 150 years), then classified them using an LDA topic model, and created networks of representatives based on the issues they talk about. Representatives are connected only if they talk about the same issues.

Shit is getting real, but given the unhinged statements Mrs. Reiche has made in the past days, I am not surprised that the left had to call on the constitutional court. Honestly, I don’t know why Reiche is so explicit and obscene; other conservatives are half as nasty.

Growing means finding new favorite albums! On my list, there are zero albums I listened to until I was in my mid twenties. (The bigger problem is that 9 slots are too damned few!)

Computational concepts remain valuable for carefully crafting theories in cognitive science (Guest & Martin, 2021; van Rooij & Baggio, 2021), but they can only flourish if we 
(a) do not confuse AI systems for minds or theories, 
(b) do not confuse machine learning for the scientific method, and 
(c) understand that our computational models can track only the scope and limits of our understanding.

The magic phrase every researcher should know which will make every infrastructure deployment for sensitive research data a guaranteed success.
An email excerpt:

"Just so you are in the know: This is how I will be approaching this on the VPS:

1. Clone the server repo onto the VPS
2. Create the correct .env file to configure the Django server
3. Run docker build
4. Pray that it doesn’t yell at me"

Point four is highlighted.

I just tried to cancel my electricity agreement (e.on), and since there were no other options, I tried their chatbot. I asked it to answer in English, the LLM responded: "Hello there! My name is Kim, I can only understand Swedish." They took THE ONE THING LLMs are useful at away from us.

Why is EVERY single app now a gray background with a bunch of rounded boxes on top of it? That gap between the toolbar and the window border on the left side is absolutely hideous. I am rarely complaining about design changes, but that is just … ugly.

I am studying political polarization, and I'm certainly thankful for getting more material to study, but … I also have a private life and appreciate having democratic rights while I'm at home.

Don't get me wrong: antisemitism is an important topic, and both ideologies have yielded dictatorships in the past. But I'd argue that, politically, the party that verbally and explicitly wants to reduce democracy should be more in focus than one that essentially compares to Zohran Mamdani.

To understand the political attitudes of the German cultural and political elites you need to understand that the fascist party won 44% in one region; the socialists won 25% in another; and the hot topic this week in the news and feuilleton is how dramatic the result of the socialists is.

Falls ihr es vor lauter Red-Scare und um sich selbst drehender Berlin-Debatten vergessen habt: In #Sachsen-Anhalt droht die erste faschistische Regierung seit 1945. Gemeinsam mit dem BSW bereitet die AfD bereits die Entmachtung des Parlaments und die Isolation der Opposition vor.

This is what LLMs are for: Give them well-defined tool call access, and let them rip through your data, while thinking about where it makes sense (or don't!) to have LLM access. It was a bummer that Siri AI couldn't access the email headers like Mail, but I completely understand the limitation.

And, what can I say? It found the correct events, adjusted the titles, added the Zoom links, and I got eleven prompts asking me to confirm the action (good!) which gave me a quick change preview. And now I have eleven correct events in my calendar, so I don't miss those lectures.

So, bummer. But what it did flawlessly is extract the presentation titles and links. So what I did was create one event at the correct time, and just copy-pasted this into all time slots for the presentations, and told it to please update the titles + links accordingly.

Hendrik Erz, PhD @hendrik-erz.de · 16/09/2026
It unfortunately could not, but not because it couldn't see the emails, but because Microsoft uses E-Mail headers to communicate the time of the events. Mail could parse them, Siri AI didn't have access to them. And Microsoft did not repeat the times in the email body.
