@JebraFaushay a place to rinse dog paws off before they come inside

@profplum99 The pain seems concentrated in Asia, Australia, and the Gulf states, and especially in Qatar.
What happened to the pivot to Asia?
Isn't OZ a reliable ally of USA? or Qatar?
Hasn't Qatar paid the Trump family enough to have their wishes considered? A gilded 400MUSD airplane ?

@noclador @StuntmanLT I've heard that it does exist, and is a requirement for the sales to Columbia, and if Canada so chooses, to Canada.

@JaneWalerud @StuntmanLT There is no Rolls Royce engine for the Gripen. Saab didn't want it. Now it does not exist.
English

@noclador @StuntmanLT The rolls royce engine in the Gripen E is not controlled by the USA:
English

@StuntmanLT Yes, both are much better in every performance aspect. Also both are, unlike the Gripen, not controlled by the US.
(If Trump doesn't want Canada to have Gripen, he will block the delivery of Gripen engines, which are all made in Lynn, Massachusetts).

On February 10, 2025, I predicted that China’s official births for 2025 would be 7.4–7.9 million. The government has now announced 7.92 million. Based on the official age structure, I estimate the fertility rate at 0.97–0.98; applying this rate to my age-structure model yields only 7.39 million births.

Money now or blood later. (And much more money.)

Most Europeans are too naive to realize that Ukrainian soldiers like these are the only thing standing between us and Russian troops. If we want to avoid fighting Russia inside the EU, we need to support Ukraine more and ensure that Russia is defeated

Great article about the broken system in the states.
Sweden for comparison
max payment for two kids at a good daycare: about 350 USD/ month.
Seeing a doctor costs 23 dollars,
a day in the hospital with all care costs I think also 25 dollars.
If you’ve spent more than iirc 150 dollars on healthcare, you get free healthcare for a year. Medicine is quite inexpensive as well.
Parental leave is 12 months, shared between the parents, with a further six months available at lower pay.
The middle class is thriving.

@APompliano @profplum99 absolutely. a GREAT piece. Perhaps one could put the lead in market commentary in a separate piece.
English

Mike Green (@profplum99) and I rarely agree on anything, but this piece he wrote is a must-read for every person in business or finance.
One of those things you read and then can't unsee what you learned.

@Trace_Cohen The list seems out of date. Northvolt went bankrupt and Getir is only operating in Turkiye now. I didn't check the others

Now imagine an AI-powered swarm of thousands of drones overtaking ship defenses in a critical global chokepoint to deliver IEDs (or worse) all at once.

A 6-year-old used a drone to deliver coffee to his parents at sea.

@davidfrum You mean the AMERICAN armed forces, not the "Trump administration".
Trump has been elected twice. He is the SCOTUS.
This might very well be the USA armed forces.
English

Hoping like hell it's the Russians who mounted this unprovoked aggression against Denmark, and not the Trump administration.

Copenhagen Police says 'capable actor' is behind drones. Drones have come from different directions & from "quite far away", which the police describe as "many kilometers". They are also working on a hypothesis that the drones may have arrived from a ship. dr.dk/nyheder/indlan…
English

Not so fast, I think.
The "deal" says that the EU will buy 750 billion USD in energy in total by 2028, or maybe 250 billion / year.
The EU has no power to buy energy; that power lies with the 27 soveriegn states and their energy companies.
That energy export number would be difficult to reach anyway; USA exported energy for 318 billion in 2024, of which less than 80 billion to the EU.
One COULD redirect a large part of all USA energy exports to the EU, I suppose, leaving other customers dry, or the states COULD export much more energy.
However, Trump's oil price target of 60 dollars/barrel makes most fracking rigs in the states unprofitable. it will be difficult to produce much more out of the Permian at those prices.
I think it's more accurate to call the tariffs a new federal sales tax on foreign goods.

@TrentTelenko airforestry.com does variable pitch propellers on their drones. They're necessary to steer while carrying a tree trunk; the center of gravity then falls well below the drone.
English

The key thing to watch as these Ukrainian interceptor drones develop is the arrival of variable pitch propellers and ducted jets replacing props entirely.

🟢 A Greenlight to remove chemicals from our crops 🟢
Double-stranded RNA has just been shown to be a rifle-shot treatment for plant viruses — "one of the most stubborn and costly challenges in global food production. Just months after proving we can control one of the world’s most destructive weeds, we’ve now shown that our RNA platform can also target viral pathogens across multiple crops, including tomatoes, corn, and soybeans.
Why does this matter?
According to the USDA, plant viruses account for over 1 billion metric tons in annual crop losses (with economic losses exceeding $30 billion and a climate impact approaching 1 GTon of CO2e). They are notoriously hard to manage, with few effective, scalable tools available.
GreenLight has demonstrated effective control of most classes of pests and diseases that affect crops, including insects, acarids, destructive fungi and weeds, and now, plant viruses." — from linkedin.com/posts/andrey-z…
And all this without chemical residues or any interaction with humans, bees or ladybugs.

We made it into @ycombinator (as guests only, though 😅). It was a pleasure to spend the evening with YC robotics founders discussing AI-first robotics infra.
