It's interesting that this seems so controversial yet clearly it's a correct statement.

Found this near Lugano. It cannot be a coincidence.

Random news: Pretty massive glacier collapsed in Switzerland today. Buried the valley in up to 200 meters of rocks and ice. Everyone was evacuated a few days ago but one village is gone. Now the river in the valley is damming up which could lead to more problems.

“Continuous Thought Machines”
Blog → sakana.ai/ctm
Modern AI is powerful, but it's still distinct from human-like flexible intelligence. We believe neural timing is key. Our Continuous Thought Machine is built from the ground up to use neural dynamics as a powerful representation for intelligence.

“At 3C of global heating, climate damage cannot be insured against, covered by governments, or adapted to. That means no more mortgages or new real estate devt, no long-term investment, no financial stability. The financial sector as we know it ceases to function and capitalism ceases to be viable.”

Replacing global memory and dense processing has been an idea floating around for at least 4 decades. Extremely hard but his approach is exciting!
Awesome to see young ETH grads doing their thing

Good explanation on understanding the tarrifs
Those trying to understand the tariffs as economic policy are dangerously naive.
No, the tariffs are a tool to collapse our democracy. A means to compel loyalty from every business that will need to petition Trump for relief.

What is (imo) missing in the wider discussion is that general approaches are currently not efficient. If you develop real-time systems with limited compute, you cannot take the most general approach. What I'd study: how can we build general and efficient systems? Then the bitter lesson is complete

Finally, someone did it! A monocular depth estimation approach that actually works on something else than pinhole cameras.
Does not even need intrinsics which surprised me.

"Fun" PyTorch fact: Submodules of an nn.Module must be initialized in the same order in different processes. Otherwise, you get wrong results silently.

Super cool paper on SFM pointcloud merging. Using structure instead of appearance has always been a thing people in my robotics/localization bubble wanted to do but this pretty much nails it.
New paper!
We merge SfM reconstructions with point cloud registration.

Code: Not yet public, but coming later.

I am looking for a paper that (iirc) shows that noise can be harmful for conditional diffusion/flow matching models when doing monodepth estimation. Anyone remembers this one?

Hippos being secretly ripped makes me happy somehow
Additionally, hippos - despite being massive - have almost no fat on them. All of that impressive bulk is muscle.
2% body fat. Compare that to Elephants, which are around 8-10%, or rhinos, which are 10-20%.
The average human is around 20-40%, for reference.
They're *all* muscle.

Europe is like a fat couch potato that is suddenly forced to perform at Ironman. Wish us good luck
The US calculus seems to be:
- The main 21st century story is US v. China.
- The US thus needs to focus on the Pacific.
- They need to peel Russia off of China and make it an ally.
- If this happens at the cost of the Europeans, so be it.
- Europe is useless as an ally and harmless as an adversary.

And there it is. Putin’s lifelong dream. After years of relentless Russian propaganda, now fully embraced by the American president and the world’s richest oligarch, millions of Americans are convinced that this is a good plan because Europe is an enemy and Putin is our friend.
