@… is `ArgumentError: UTF-16 string byte length (51) is not a multiple of 2` something that should be handled in my PR or in TruffleRuby?
ArgumentError is semantically off but I vaguely remember that it was some encoding performance stuff or so?
It would be nice if it would act like the other Rubies though 😄

After the building fire, Hong Kong summoned AFP, FT, NYT, AP, Bloomberg, and WSJ journalists, telling them to avoid "trouble making", and arrested a commentator (Committee to Protect Journalists)

Hong Kong arrests commentator, summons international media over deadly fire - Committee to Protect Journalists
Updated on December 8, 2025 2:31 AM EST New York, December 8, 2025—Chinese and Hong Kong authorities must immediately stop harassing journalists, release news commentator Wong Kwok-ngon, and allow the media to freely cover the city’s most deadly fire in decades, the Committee to Protect Journalists said Monday. In a rare move, Beijing’s national security arm...

Hora de me arrumar e ir ao trabalho. Mas tš um friozinho delicioso e meu gato estš me convidando a ficar na cama enrolado no cobertor, vendo TV ou lendo um livro. Como faz pra não precisar trabalhar? rs

Cosmic topology. Part IIb. Eigenmodes, correlation matrices, and detectability of non-orientable Euclidean manifolds
If the Universe has non-trivial spatial topology, observables depend on both the parameters of the spatial manifold and the position and orientation of the observer. In infinite Euclidean space, most cosmological observables arise from the amplitudes of Fourier modes of primordial scalar curvature perturbations. Topological boundary conditions replace the full set of Fourier modes with specific linear combinations of selected Fourier modes as the eigenmodes of the scalar Laplacian. In this pape…

Asteria: Semantic-Aware Cross-Region Caching for Agentic LLM Tool Access
Large Language Model (LLM) agents tackle data-intensive tasks such as deep research and code generation. However, their effectiveness depends on frequent interactions with knowledge sources across remote clouds or regions. Such interactions can create non-trivial latency and cost bottlenecks. Existing caching solutions focus on exact-match queries, limiting their effectiveness for semantic knowledge reuse. To address this challenge, we introduce Asteria, a novel cross-region knowledge caching…

A Function-Set Framework: General Properties and Applications to Modal Logic
Representations are essential to mathematically model phenomena, but there are many options available. While each of those options provides useful properties with which to solve problems related to the phenomena in study, comparing results between these representations can be non-trivial, as different frameworks are used for different contexts. We present a general structure based on set-theoretic concepts that accommodates many situations related to logical and semantic frameworks. We show the…

Spontaneous stochasticity in the Armstrong-Vicol passive scalar
Spontaneous stochasticity refers to the emergence of intrinsic randomness in deterministic systems under singular limits, a phenomenon conjectured to be fundamental in turbulence. Armstrong and Vicol recently constructed a deterministic, divergence-free multiscale vector field arbitrarily close to a weak Euler solution, proving that a passive scalar transported by this field exhibits anomalous dissipation and lacks a selection principle in the vanishing diffusivity limit. We show that this adve…
