every human […] had a comlog with biomonitor, many had implants, and each of these was tuned to the music of the datasphere, monitored by elements of the datasphere, dependent upon functions of the datasphere-so humans accepted their lack of privacy. The fall of Hyperion, Dan Simmons, 1990

I am turning into a bear, enjoying the relative solitude of a low density residential neighborhood. But today, eating at my favorite ramen place, and being offered dark glasses by random people gathering in the street to see the eclipse, Nørrebro reminded me of why dense neighborhoods are special

Periodisk opråb at i 1970’ernes Italien var det muligt at rejse cirka samme distance som Aarhus–København på 90 minutter i stedet for de nuværende 210 (forsinkelser tilladt), med den ekstra lille komplikation, at man også lige skulle igennem en 2.000 meter høj bjergkæde.

Jeg bliver ved at minde folk at i Italien - ikke Japan eller lignende - har det været muligt at køre Aarhus-København distancen på 90 minutter siden de 1970’re, med den lille krølle at skulle køre over en 2000m høj bjergkæde

Weekend, and time to fight against nature. The bad: Thicket of thorns are awful and I understand why back in the days they’d just set the whole thing on fire. The good: The 4yo can play he is Prince Philip on its way to slaying the dragon (saving the princess is WAAAY down the priority scale)

Per aumentare la consapevolezza non vedo altra opzione che una forte presa di posizione da parte dei leader politici nazionali. Che però accade molto raramente. E non capisco perché. Cosa trattiene Meloni etc? Han davvero paura di perdere terreno vs Salvini?

“Just a few thousand kilometers from Denmark, Ukrainians are fighting for their freedom. For almost four years, they have persevered, held their ground and held on to their right to exist as a free and independent country.” Fine words by King Frederik X 🇺🇦

…through which it could occur. 1) regulations. The Danish FSA has a very strong prior against variable rate mortgages with io. Hence regulation restricts them in some areas and for some hhd (typically first time buyers). But 40y F5s would open up the yellow and pink dots in the table

But - IS it good? From the individual point of view 👍. You can afford to stay in your house for life! But that means that in DK the great majority of older owners now lives in large dwellings (four rooms or more), even after the age of 75. Back to square one. Is that good for first time buyers?
110
Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
For most people, their largest asset is their home. For most older people, that’s completely irrelevant. What good does it do to you to have a half-million$ home if you can’t put bread on the table? You can’t eat bricks. Well, most of us can’t. So you are forced to sell your home.

Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
Enter the one group of people who undoubtedly benefited most from IO mortgages. Boomers! A great analysis by @henrikyde.bsky.social and coauthors shows that IO mortgages have financed billions in consumption by older home owners. That makes total sense.
140
Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
The point is, that the most important discussion about such a measure should be about these types of effects. Who gains? Who loses? Instead most critics have focused, not surprisingly, on an entirely wrong point. Dying before paying off a mortgage is bad! Well, that’s good, actually!

Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
Did it help first-time buyers? Mmmh… Nope. The debate is not quite settled, but much points to the mechanism above - in line with economic theory. It likely created a capital transfer to existing owners. Claes Backman has a paper on this btw claesbackman.github.io/Papers/DkHou...

Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
Interest-only (IO) mortgages! That is, (for a time), you do not pay down your debt. Amortization is frozen, you only pay interest on your debt. Introduced in ‘03 (also to help first time buyers), they have been hugely popular. Today, one in two home financing solutions is at least partially IO
110
Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
Let’s start with what the debate should be about. Longer mortgages will likely NOT help first-time buyers. Supply&demand. Push demand, price rises. Price rises => capital gain to existing home owners. Who pays? First-time buyers. We might have seen it in 🇩🇰 with another mortgage innovation...

Alessandro Martinello 🇪🇺 @alemartinello.com · 09/11/2025
In an interesting turn of events, US and Danish government came up with the same to help with the affordability crisis: longer mortgages! That has sparked some backlash. But in the US, it seems the discussion is focusing on the wrong stuff. Well, let’s try to learn from 🇩🇰.

Think this explains it well. It can be innocuous, but say I am using the same dataset to train two different models for two different purposes (not unusual), I would end up with the same train-test split. Same with bootstrapping iterations. Overall defeats the randomization purpose.

The drones in Copenhagen have been a painful reminder at completing the preparations recommended by the 🇩🇰 government in case of sabotage to critical infra. Last items: water for three days, emergency radio. If you haven’t done it already, it is a good time to do it now!
