People might continue reading Cybernews after this, but not people in the cybersecurity business, that's for sure. Let's hope this stops them from promoting their baloney.

From dumps with no login credentials at all, to direct connections to txtbase leaks from Telegram and old breaches, Cybernews tried to pass this as new and unseen, but data says otherwise.

The SagbiHomotopy.jl package for solving polynomial systems
We present the Julia package SagbiHomotopy.jl for solving systems of polynomial equations using numerical homotopy continuation. The package introduces an optimal choice of a start system based on SAGBI homotopies. For square horizontally parameterized systems, where each equation is a linear combination of a given set of polynomials, SAGBI homotopies significantly reduce the number of solution paths to track compared to polyhedral homotopies currently used by default in most software for numer…

Enhanced PDHG for Linear Programming with Online Preconditioning
We present an online preconditioning technique for the primal-dual hybrid gradient (PDHG) algorithm for linear programming (LP). The method adaptively updates primal and dual preconditioners using an online optimization framework. To improve its practical performance, we introduce several algorithmic enhancements, including using normalized online loss functions and updating preconditioners infrequently. We implement the technique on top of vanilla PDHG and the GPU-based LP solver cuPDLP.jl, an…

Computeralgebra news:
I'm very happy to read that a big pull request to the OSCAR computer algebra system has been merged today.
My student Anna Hofer has been working on this for months and now you can compute injective resolutions and local cohomlogy over monoid algebras, including singular ones! All credit to Anna and thanks to lots of support from the OSCAR team! @…

A Common Interface for Automatic Differentiation
For scientific machine learning tasks with a lot of custom code, picking the right Automatic Differentiation (AD) system matters. Our Julia package DifferentiationInterface.jl provides a common frontend to a dozen AD backends, unlocking easy comparison and modular development. In particular, its built-in preparation mechanism leverages the strengths of each backend by amortizing one-time computations. This is key to enabling sophisticated features like sparsity handling without putting addition…

Packing3D: An Open-Source Analytical Framework for Computing Packing Density and Mixing Indices Using Partial Spherical Volumes
Accurate quantification of local packing density and mixing in simulations of particulate systems is essential for many industrial applications. Traditional methods which simply count the number of particle centres within a given volume of space (cell) introduce discontinuities at cell boundaries, leading to unreliable measurement of packing density. We introduce Packing3D.jl, an open-source Julia package providing analytic, partial-volume calculations for spheres intersecting Cartesian and cyl…
