In May 2025, a high-profile lunch in Riyadh brought together Donald Trump,
the Crown Prince,
and a group of Silicon Valley billionaires and executives.
The guest list assembled by Elon Musk (Tesla, xAI, SpaceX) and arriving by their own jets:
Sam Altman (OpenAI), Jensen Huang (Nvidia), Alex Karp (Palantir), Dara Khosrowshahi (Uber), Ruth Porat (Alphabet/Google), Alexandr Wang (Scale AI), Travis Kalanick (Cloud Kitchens, former Uber CEO), Stephen Schwarzman (Blackstone…

just got off the 5, crossed the street, and could already see the 49 I’m transferring to. it arrived before I could finish typing this post. Muni service is in many cases already quite good, we must defend it

Desculpem eu mandar vídeo de Instagram aqui, mas esse vale a pena. Podem clicar sem medo de arrependimentos rs.

É, Trump, você deveria ter aprendido que não se mexe com o Brasil, o povo brasileiro é o rei do marketing na internet! rs

Isogeny graphs of abelian varieties and singular ideals in orders
Famously, Kohel proved that isogeny graphs of ordinary elliptic curves are beautifully structured objects, now called volcanos. We prove graph structural theorems for abelian varieties of any dimension with commutative endomorphism ring and containing a fixed locally Bass order, leveraging an ideal-theoretic perspective on isogeny graphs. This generalizes previous results, which relied on restrictive additional assumptions, such as maximal real multiplication, ordinary, and absolutely simple (B…

A Survey of Deep Learning Video Super-Resolution
Video super-resolution (VSR) is a prominent research topic in low-level computer vision, where deep learning technologies have played a significant role. The rapid progress in deep learning and its applications in VSR has led to a proliferation of tools and techniques in the literature. However, the usage of these methods is often not adequately explained, and decisions are primarily driven by quantitative improvements. Given the significance of VSR's potential influence across multiple domains…

Love beyond Einstein: Metric reconstruction and Love number in quadratic gravity using WEFT
We study tidal Love numbers of static black holes in four-dimensional quadratic theory of gravity, extending the result of GR. We use worldline effective field theory (WEFT) methods to compute metric perturbations from one-point functions, treating the higher-derivative terms perturbatively. We show that insertions of scalar fields on the worldline induce non-zero tidal tails, and the corresponding Love number displays no RG running. The same conclusion holds for the insertions of tensor fields…

Quase quarenta minutos perdidos de trabalho porque os gatos exigiram minha atenção e aí eu fiquei brincando com eles com a varinha. Agora estou ainda mais ferrado do que antes, mas sem nenhum arrependimento rs.
