This is very cool. I hope others copy this excellent work, and that we all learn from greater data transparency

This agreement on the citizenship laws is a big deal, and the right decision. It is also against what Merz said on the campaign.

Excellent piece from @andrearoemmele.bsky.social in @spiegel.de today. Indeed, time to change the status quo in Germany’s democracy

This is an important point. If this all morphs into a financial crisis the nature of the game is different, and more dangerous. The question is whether Trump can calm markets. The response might have to come from the Fed.

This is indeed the best way forward—a free trade coalition of the willing, to include the UK , EU, Japan, Canada, and (he notes) even China. I would add that the domestic politics to do this are tough. I would still encourage the leaders of these countries to try. www.thetimes.com/article/06e1...

I have been hearing the Chinese perspective on the US too. It is that the US is having its Mao Moment, it’s Cultural Revolution. Consistent in both is deep skepticism of academics. Friedman goes through the geopolitical consequences and why this time is a lot worse for the rest of the world.

On the tariffs @strangeloopcanon.com over at the other place has pretty convincing evidence that the White House may have used LLMs to come up with its tariff model and that that evidence may have come from LLM scraping of a Peter Navarro book. We are in the dumbest AI timeline.

Trump has been able to operate with impunity at home. But there will be consequences abroad. The idea that you can attack allies economically, intervene in their politics, and ignore their security concerns, all while expecting them to buy your products like nothing has changed is laughable

This is an intriguing piece that argues how US policy will hurt American tech, and American factories. Just when China moves ahead in some tech fields the US cracks down on researchers at home and makes inputs from abroad more expensive. www.nytimes.com/2025/04/02/o...

Something in common in these stories is that one’s phone is checked. As university leadership we have an obligation to protect our people. European universities routinely make burner phones available for staff going to China. One should consider this for staff headed to the US as well.

This is the fourth story I have seen about different Germans with seemingly correct paperwork either being sent back or detained this week. I have heard two personal stories. It is getting to the point where it is hard to recommend to German friends to go to the US. www.spiegel.de/panorama/cel...

This is where EVs need to go. I hope the claim is true, and that this becomes standard for all EVs in the coming years.

Indeed. This is one reason why a Masters in Data Science for Public Policy literally pays off. And you do work that benefits the public.

There was a time when the Germans would have been front and center as well. Lame duck Chancellor? This time it is about security? Germans wouldn’t be expected to contribute troops on the ground in any peace deal?

The party line by the IRS has been that it is illegal to share IRS data. There isn't a "to help deport" people exception in the Privacy Act.

I got laid off today, with the rest of 18F. 18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it. We made this website to tell our story: 18f.org

I understand more defense spending. But the cut to development spending is a bad decision. A Tory-Lib Dem government in 2010 made big cuts in most areas but kept aid spending at .7 percent of GDP. A Labour government with now drop spending to less than half that. www.theguardian.com/politics/202...

84 percent turnout. Decent jump for Germany. Huge difference to what one sees in the US.

The German polls are closed. The big question is whether the FDP and BSW manage 5 percent and get in after all. But no denying a big slap to the SPD, and the rise of the AfD especially in the East.

Scoop --> Trump-Musk cuts just resulted in the firing of numerous top researchers at NIH's center for combating Alzheimer's, sources tell me. They predict big setbacks to fighting dementias. This cause was once championed by *Republicans.* Details here: newrepublic.com/article/1917...

If you wanted to cut waste, fraud, and abuse, you would empower the inspectors general. If you wanted more waste, fraud, and abuse, you would fire them.

There hasn't actually been a serious border security problem between Canada and the US. Wanna know a good way to create one? Create incentives in the tens of billions of dollars for successful smuggling operations.

Curious how European anti-immigration politicians and opinion-leaders feel about an immigrant influencing a national election by pumping $288 million into one party. You know, because they’re worried about “foreign elites” and “sovereignty.”

If a Democrat fired 100 FAA employees and put a freeze on hiring air traffic controllers 8 days before an airport plane crash, there would be a right-wing and media frenzy for weeks.
