Python calculation based on principle of argument (theory of functions of a complex variable)

Principle of Argument doesn’t provide any information about values of polynomial zeros inside predefined circle as well as locations of these zeros on complex plane. Classic math just says how many polynomial zeros we get inside given circle and nothing else. Library cxroots imported in python module provides object Circle having method roots to achieve the goal to get actual zeros values.

SystemRescue 13.00 released

SystemRescue 13.00 has been released. The
SystemRescue distribution is a live boot system-rescue toolkit, based
on Arch Linux, for repairing systems in the event of a crash. This
release includes the 6.18.20 LTS kernel, updates bcachefs tools and
kernel module to 1.37.3, and many
upgraded packages
. See the step-by-step guide for
instructions on performing common operations such as recovering files,
creating disk clones, and resetting lost passwords.

Ubuntu 26.04 Showing Nice Gains Over Ubuntu 25.10 On AMD Ryzen 9000 Series

While having the new System76 Thelio Mira in the lab I ran some benchmarks of Ubuntu 24.04 LTS vs. 26.04 development on that AMD Ryzen 9000 series powered desktop. Those results were interesting for how the Ubuntu performance has changed over the past two years, but even if drilling down to just the past six months there have been some nice gains on the AMD Zen 5 desktop. In this article is a look at how Ubuntu 26.04 in its near-final state is performing relative to Ubuntu 25.10 with this Ryzen 9 9950X desktop.

Open-Source RadeonSI+Rusticl Nearing Formal OpenCL 3.0 Conformance

The open-source RadeonSI Gallium3D driver with Rusticl for modern Rust-based OpenCL is nearing formal OpenCL 3.0 conformance with all necessary OpenCL test cases passing. Making this all the more interesting is that this is the first modern AMD graphics hardware in a decade likely to see formal recognition for OpenCL conformance with AMD having not submitted any of their own OpenCL conformance results since 2015…

[$] Rust’s next-generation trait solver

Rust’s compiler team has been working on a long-term project to

rewrite the trait solver
— the part of the compiler that determines which
concrete function should be called when a programmer uses a trait method that is
implemented for multiple types. The rewrite is intended to simplify
future changes to the trait system, fix a handful of tricky soundness bugs, and
provide faster compile times. It’s also nearly finished, with a relatively
small number of remaining blocking bugs.

Intel FRED Appears Ready To Enable By Default With Linux 7.1

Last week I ran benchmarks quantify the performance benefit to Intel FRED for Flexible Return and Event Delivery initially found with the new Core Ultra Series 3 “Panther Lake” processors and also for upcoming Nova Lake and Diamond Rapids CPUs. The FRED performance impact was very beneficial across a variety of workloads but rather strangely was not enabled by default. Mere hours after publishing that article, an Intel engineer posted a patch to enable FRED by default. Now this week that patch appears all-set for merging with the upcoming Linux 7.1 merge window…
