Kommunwahl MΓΌnchen ballot

Kommunwahl MΓΌnchen ballot

After seeing the ballots for Munich's municipal election, I feel bad for spending my energy on voting theory rather than doing something about this.
One of three tasks: "Distribute up to 80 points on more than 1000 candidates (3 points max per candidate)"

Beyond the benefits, AI’s biggest negative externality is the paralyzing uncertainty it spreads, especially among young people. It’s very unclear what you need to do to be successful 10 years from now.

Interesting realization: Social choice theory, mechanism design, and theoretical computer science peaked in the 1970s and 1980s.

Most of my (few) interactions with LLMs end with me insulting the AI and telling it how stupid it is. I fear this may reduce my chances of survival when the takeover begins.

Thx, will give it a try. I did like The Undoing. Perhaps the only miniseries Iβ€˜ve seen.

I find it especially disappointing to read that the makers of these shows are unsure how the story will continue in the next season. I think I've read this in interviews with the makers of Severance (Stiller) and Pluribus (Gilligan).

Season 1 of The Morning Show was great and had a satisfying ending. Yet I didn't watch the second season. The Undoing was perfect, but that's a mini-series.

Every TV series I've watched has left me disappointed at the end of the first season due to unanswered questions and loose ends: 24, Prison Break, Westworld, Big Little Lies, Cobra Kai, Severance, Pluribus. I've never watched a second season. It seems I just prefer movies.

"Why doesn't my kid stop dropping his pizza on the floor and laughing?" That puts his repeated remarks about ChatGPT's PhD-level intelligence into perspective.

I can't stop thinking about this article. For the record, I am still impressed when undergrads get a single paper before grad school... πŸ˜…

I love Pluribus.

What do people think about IJCAI's Primary Paper Initiative ($100 paper submission fee, first submission is free)? The proceeds will be "exclusively directed toward the support of the reviewing community".

After Russia 2018 and Qatar 2022, FIFA gives us Trump 2026.

And 8 of the 12 teams that place 3rd will also advance to the knockout round. The group stage will be a farce.

Oh right. I didn't realize they had been absent since 1998!

They participated four times when there were only 4 groups 😊 Four-time champion Italy is still not qualified 😧

Until 1982, there were 4 groups at FIFA World Cups. Having 12 groups is just ridiculous. Germany is facing CuraΓ§ao, the smallest nation ever to participate in a World Cup. They have a population of approximately 150,000, comparable to cities such as Heidelberg, Darmstadt, and Ingolstadt.

All these acronyms appear in his 1986 book "The Logic of Collective Choice".

Political scientist Thomas Schwartz (✝ 2024) surely had a great sense of humour when it came to acronyms:

GEneralized Top CHoice Assumption (GETCHA)
Generalized Optimal CHoice Axiom (GOCHA)
SOlution COndition (SOCO)
MUltiSTAge CHoice operation (MUSTACH)
BInary-CHoice property (BICH)

Democracy Reform Primer Series

Great series of primers on democracy reform that specifically address problems in the US: the electoral college, private fundraising, gerrymandering, unavailability of vote-by-mail, first-past-the-post (plurality), etc.
Don't miss the article about Condorcet voting.

Interesting German article that proposes using a Condorcet-consistent method for Bundestag elections.

Nowadays, every single AAAI publishes more papers per year than have ever appeared in, say, Social Choice and Welfare (ca. 2k papers since 1984) or Games and Economic Behavior (ca. 3k papers since 1989). There’s just no way that so many papers deserve to be published. In any area.

AAAI 2026 has received more than 29k submissions. Peer-reviewing is completely broken for AI. It’s not only the well-documented issues, such as self-nominated PC members, mismatched referees, useless reports, fraudulent submissions, low-quality papers, etc.
