kh2d-solver: A Python Library for Idealized Two-Dimensional Incompressible Kelvin-Helmholtz Instability
We present an open-source Python library for simulating two-dimensional incompressible Kelvin-Helmholtz instabilities in stratified shear flows. The solver employs a fractional-step projection method with spectral Poisson solution via Fast Sine Transform, achieving second-order spatial accuracy. Implementation leverages NumPy, SciPy, and Numba JIT compilation for efficient computation. Four canonical test cases explore Reynolds numbers 1000--5000 and Richardson numbers 0.1--0.3: classical shear…

From Individual to Multi-Agent Algorithmic Recourse: Minimizing the Welfare Gap via Capacitated Bipartite Matching
Decision makers are increasingly relying on machine learning in sensitive situations. In such settings, algorithmic recourse aims to provide individuals with actionable and minimally costly steps to reverse unfavorable AI-driven decisions. While existing research predominantly focuses on single-individual (i.e., seeker) and single-model (i.e., provider) scenarios, real-world applications often involve multiple interacting stakeholders. Optimizing outcomes for seekers under an individual welfare…

Anwar Floyd-Pruitt has passed away. I met him at UWM a decade ago, and he was always such a kind and creative person. I last saw him at Saint Kate and had a great conversation with him about his art, while surrounded by the art he was creating at the time. I am gutted... Anwar and his art will be sorely missed.

A profile of 6-year-old Ramp, which has grown to a $22.5B valuation as it expanded beyond corporate cards to tools for expense reporting, bill payment, and more (Leo Schwartz/Fortune)
https://fortune.com/article/ramp-american-express-corp…

Ramp is taking aim at American Express by upending corporate credit cards. Can the $22.5 billion startup live up to the hype?
With $1 billion in revenue, Ramp has grown at hyperspeed amid the AI boom and corner-office financial anxiety.

My install instructions for KDE 6 Wayland on FreeBSD have been updated.
First of all I changed the base to KDE and KDE base apps, instead of just a very minimal install. This follows the recommended install by KDE more closely.
Second: the browser of choice has been changed to Vivaldi and I have included a how-to-update the script and make Vivaldi run under FreeBSD.
Which you can apply anywhere on FreeBSD of course ;-)
Thanks to all for the positive feedback!

Неожиданная музыкальная рекомендация — анархо-шансон.
Незамысловатая мелодия и примитивный вокал "блатняка" добавляют искренности, трогающие за самую душу тексты не оказываются спрятаны за художественной мишурой.

Simple Projection Variants Improve ColBERT Performance
Multi-vector dense retrieval methods like ColBERT systematically use a single-layer linear projection to reduce the dimensionality of individual vectors. In this study, we explore the implications of the MaxSim operator on the gradient flows of the training of multi-vector models and show that such a simple linear projection has inherent, if non-critical, limitations in this setting. We then discuss the theoretical improvements that could result from replacing this single-layer projection with …
