Sembra un progetto interessante ma con le fregature delle organizzazioni non profit spero che questo non sia un'altra di queste, non ho tanto tempo di leggerlo adesso ma questo promette bene contrario ai social network di oggi.

Bluesky era uno di Jack Dorsey che poi è stato affidato ad uno squallido cryptomane che ha tentato di diffamare il fediverso stesso promuovendo le stesse ideologie di merda che condivideva Musk e X.

“Silicon Valley isn’t building apps anymore. It’s building empires. Under the banner of "patriotic tech", this new bloc is building the infrastructure of control—clouds, AI, finance, drones, satellites—an integrated system we call the Authoritarian Stack. (…) these firms now operate as state-like powers—writing the rules, winning the tenders, and exporting their model to Europe, where it poses a direct challenge to democratic governance.”

Someone ought to get the ladder out to get the suncream on those giraffe noses before they get sunburn.

Looking back to sunnier & warmer times in Tier Park, Berlin.

Forstår dere hvor syke i hodet disse menneskene e? #SilikonDalBaronene er så svidd som det går ann å bli og dem ville med glede ofret demokrati, dine rettigheter samt friheter, for å oppnå ny status selv. De tørker seg selv i ræven med vestlige verdier.

Palantir CEO Says a Surveillance State Is Preferable to China Winning the AI Race

I can't believe I didn't know this fact before today - it seems so fundamental.

If you have a real symmetric matrix A, and pick some unit vector x, then it's standard textbook material that x.Ax (the Rayleigh quotient) is bounded by the smallest and largest eigenvalues. So what happens if I pick a random unit vector, how is x.Ax distributed?

Let's jump to the case of a Hermitian matrix A and a random unit vector on the complex sphere. How is T=conj(x).A.x distributed? Again it's standard that it's bounded between the smallest and largest eigenvalue.

We can start with a 2x2 matrix A. First surprise to me: T is distributed *uniformly* between the two eigenvalues.

The first plot below is the histogram of values of T for 1,000,000 vectors x and a randomly chosen Hermitian matrix A. The yellow lines mark the two eigenvalues.

Now try 3x3. Remarkably the distribution is piecewise linear with the break points at the eigenvalues.

And let's jump to 5x5. We get the third plot, whose curve is given by a cubic B-spline with control points given by the eigenvalues.

Bizarrely you can prove you always get B-splines making this one of the few times I've seen B-splines in "nature", so to speak.

This is a purely mathematical result but I found it in this paper on wave transport through random media: https://arxiv.org/abs/2511.04602

My calculations (pretty much the same as the paper) are here: https://colab.research.google.com/drive/1g7ImBblYAsninp5-sr6uWQTVfTYurerE?usp=sharing
