Emma gör rätt, fler politiker borde lämna X. https://www.svt.se/nyheter/inrikes/emma-wiesner-c-lamnar-x-for-tufft-klimat

Emma Wiesner (C) lämnar X: ”För tufft klimat”
Nyligen meddelade centerledaren Anna-Karin Hatt att hon lämnar partiledarrollen efter hat och hot. Nu säger Europaparlamentarikern Emma Wiesner (C) att hon överger plattformen X på grund av det hårda debattklimatet. – Man drar sig för att skriva det man vill. Man får höra kommentarer om att man är ful och fet, säger hon i SVT:s 30 minuter.

Character theoretic techniques for nonabelian partial difference sets
A $(v,k,λ, μ)$-partial difference set (PDS) is a subset $D$ of size $k$ of a group $G$ of order $v$ such that every nonidentity element $g$ of $G$ can be expressed in either $λ$ or $μ$ different ways as a product $xy^{-1}$, $x, y \in D$, depending on whether or not $g$ is in $D$. If $D$ is inverse closed and $1 \notin D$, then the Cayley graph ${\rm Cay}(G,D)$ is a $(v,k,λ, μ)$-strongly regular graph (SRG). PDSs have been studied extensively over the years, especially in abelian groups, w…

Wait, don't i know someone named Russ Nelson?
Probably a different guy... https://flipboard.com/@npr/all-things-considered-ji18657oz/-/a-sasZChVSTP--xxajoEyJ_w:a:3195441-/0

$2$-split from Feynman diagrams and Expansions
In this paper, we investigate the $2$-split behavior of tree-level amplitudes of bi-adjoint scalar (BAS), Yang-Mills (YM), non-linear sigma model (NLSM), and general relativity (GR) theories under certain kinematic conditions. Our approach begins with a proof, based on the Feynman diagram method, of the $2$-split property for tree-level BAS$\oplus$X amplitudes with $\mathrm{X}={\mathrm{YM},\mathrm{NLSM},\mathrm{GR}}$. The proof relies crucially on a particular pattern in the Feynmam rules of va…

NeLLCom-Lex: A Neural-agent Framework to Study the Interplay between Lexical Systems and Language Use
Lexical semantic change has primarily been investigated with observational and experimental methods; however, observational methods (corpus analysis, distributional semantic modeling) cannot get at causal mechanisms, and experimental paradigms with humans are hard to apply to semantic change due to the extended diachronic processes involved. This work introduces NeLLCom-Lex, a neural-agent framework designed to simulate semantic change by first grounding agents in a real lexical system (e.g. En…

Ew, http://firecrawl.dev replaced a bike store in the Lower Haight. Their product is exactly one of the unethical parts of AI. They are building a content scraper to take this like this Toot and feed it into your model.

XR Blocks: Accelerating Human-centered AI + XR Innovation
We are on the cusp where Artificial Intelligence (AI) and Extended Reality (XR) are converging to unlock new paradigms of interactive computing. However, a significant gap exists between the ecosystems of these two fields: while AI research and development is accelerated by mature frameworks like JAX and benchmarks like LMArena, prototyping novel AI-driven XR interactions remains a high-friction process, often requiring practitioners to manually integrate disparate, low-level systems for percep…

English is an amazing language. We have two similar if folksy / archaic expressions: "to cotton to" and "to cotton on to". They mean different things. https://www.phrases.org.uk/meanings/cotton-on.html
