Germany's Die Linke won last month's Berlin election on a pledge to socialize ~220k flats owned by large landlords. A thread on why housing expropriation is a successful campaign promise, how Berlin's flats became an asset class, and what expropriation would do. 🧵
Front page of die tageszeitung (taz), 21 September 2026: Die Linke supporters cheer under the headline 'CDU enteignet' ('CDU expropriated'). Photo: Jörg Carstensen/imago.Bar chart of the 2026 Berlin state election (second votes): Linke 25.7% (2023: 12.2%), CDU 18.8% (28.2%), AfD 16.3% (9.1%), Greens 14.3% (18.4%), SPD 12.1% (18.4%), BSW 4.7%, FDP 2.5% (4.6%).

We git push —force-with-lease’d these tiny feet into the GitLab socks. Actual deployment is still a few sprints ahead, but staging looks very promising.

It’s a pyramid system built on the next generations being large and productive enough to sustain the previous ones. In addition, over 20% of the state budget is spent on pensions as well. Overall, Germany is spending 340 billion € on pensions per year.

It’s mostly pay-as-you-go systems. In Germany, we are paying 18.6% of our salary up to a threshold into the system. It is directly paid to pensioners. In return we get points that reflect how much pension we’ll get. Because there is no investment, there is little liquidity in our banking system.

Guys, guys!!! I think I have figured out a solution. I call it "German AC"!
Illustration of Maxwell's demon from Wikipedia
By User:Htkym - Own work, CC BY 2.5, https://commons.wikimedia.org/w/index.php?curid=1625737

Labels have been added: Maxwell's demon is German AC, one gas chamber is inside, the other one outside.
The second panel says: The German AC only lets fast (= hot) molecules pass outside, thus lowering room temperature without creating surplus heat.

Maxwell's demon is a thought experiment to ostensibly disprove the second law of thermo dynamics. From wikipedia:
In the thought experiment, a demon controls a door between two chambers containing gas. As individual gas molecules (or atoms) approach the door, the demon quickly opens and closes the door to allow only fast-moving molecules to pass through in one direction, and only slow-moving molecules to pass through in the other. Because the kinetic temperature of a gas depends on the velocities of its constituent molecules, the demon's actions cause one chamber to warm up and the other to cool down. This would decrease the total entropy of the system, seemingly without applying any work, thereby violating the second law of thermodynamics.

From a product perspective, the question is what you actually need. Storing a few files and a bit of metadata long term isn’t hard or expensive. Just vibe code yourself or fork Forgejo or Gitea. The long term funding problem is the core issue to solve here and what ultimately kills OSF.

Martin Brümmer @derbruemmer.bsky.social · 12/05/2026
For use cases where you arguably want long term, stable data storage, these platforms are just not the right fit. They’ll introduce data retention policies and start monetising more, not even talking about the availability issues.

Martin Brümmer @derbruemmer.bsky.social · 12/05/2026
The big platforms will increasingly be hammered by AI contributions, leading to stronger restrictions, rate and usage limits, as well as usage billing in order to recoup infrastructure costs. Providing a product for free is becoming less viable as usage explodes.

Apparently there is a survey showing that a substantial number of US Americans mistakenly believe that Noah of Noah's Ark was married to Joan of Arc. What those who are gloating are missing is that this version of history would be quite sick.

I started reading up on the whole "loneliness pandemic" narrative because this seems like a literature where the age-period-cohort problem may be relevant (or maybe it isn't?). Here's data from Australia (HILDA), average agreement with the statement "I often feel very lonely" (SD of ca. 1.8).>

NEW article by me! We can now visualize pathogens down to atoms; design vaccines in weeks; manufacture them in microbial factories; engineer them more precise than ever before. We're living through a golden age of vaccine development, but only if we continue to invest in them.

I think the drone motors specifically are high RPM, low torque brushless DC motors while for ice cream you want low RPM with high torque. You can convert that with a gearbox but you don’t want the drone sound continuously. I would just look for a brushless DC motor here and metal churners.

Haidt is "stunned" that ChatGPT asked how it would threaten youth reveals that its plan would be what Haidt has argued in his books. The secret plan! There should be some way to rescind the doctorate of any commentator on digital media who interprets ChatGPT output like this. I am not joking.

Imagine you lived in the 18th century. Smallpox kills 1 in 3 cases. Yet you can’t culture pathogens, don’t know germ theory, and have no idea what a virus is. How would you invent a vaccine? In a new episode of HARD DRUGS, we trace the history of vaccines!

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵
