Tiling with Three Polygons is Undecidable
We prove that the following problem is co-RE-complete and thus undecidable: given three simple polygons, is there a tiling of the plane where every tile is an isometry of one of the three polygons (either allowing or forbidding reflections)? This result improves on the best previous construction which requires five polygons.

Generalized Segal-Bargmann transform for Poisson distribution revisited
For $α>0$ and $σ> 0$, we consider the following probability distribution on $α\mathbb N_0$: $π_{α,σ} = \exp \big(- \fracσ{α^2}\big) \sum_{n=0}^{\infty} \frac{1}{n!} \big(\fracσ{α^2}\big)^n δ_{αn}$, where $δ_y$ denotes the Dirac measure with mass at $y$. For $α=1$, $π_{1,σ}$ is the Poisson distribution with parameter $σ$. Furthermore, the centered probability distribution $\tilde π_{α,σ} = \exp \big(- \fracσ{α^2}\big) \sum_{n=0}^{\infty} \frac{1}{n!} \big(\fracσ{α^2}\big)…

🤔 Looking at this UI, Forem could probably implement ActivityPub at this point.
Every logo is a server. "Forem feed" = Federated timeline. "Follow" = follow and adding their Local timeline to my Following timeline? 🤔

Stablecoin Card Startup Rain Raises $58 Million Led By Sapphire Ventures
Rain, a stablecoin-backed card issuer that works with Visa, said it raised $58 million in Series B round led by Sapphire Ventures, just months after its last fundraising round, demonstrating once again investor enthusiasm for crypto startups flowing from congressional passage of stablecoin legislation in July. With the deal, Rain’s valuation increased nearly six times from its $24.5 million

Records show China's Starlink rivals have only ~120 satellites in orbit, less than 1% of their goal, vs. SpaceX's ~8,000, underscoring how far behind they are (New York Times)

Why Isn't China Catching Up With Elon Musk’s Starlink?
China’s biggest networks have deployed less than 1 percent of their planned satellites, falling far behind SpaceX for dominance in space communications.
