For conversion three different plotting scripts building each one it's own surface into a multi-threaded (multi-process) version, we separate the code logic for each surface into a separate task. This allows CPU to calculate simultaneously the paraboloid, sine wave, and Möbius strip.
Setup python3.14.3t on Debian Trixie/Forky along with aqtinstall via pyenv
Command-line utility "aqtinstall" enables plotting in Python 3.14.3t by automating the installation of Qt binaries (e.g., PyQt6 ) , which are required by libraries like Matplotlib to render interactive graphs. It serves as a command-line alternative to the official Qt installer, facilitating the setup of necessary GUI frameworks, often in CI environments or specific Python versions.
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.
Linux Just Changed Forever, New Feature That Could Replace Windows & macOS in 2026
Linux is evolving faster than ever, and this new breakthrough feature could completely change the future of operating systems. From immutable Linux systems and universal apps to better gaming support, stronger security, and improved performance, Linux is becoming a serious competitor to Windows and macOS. In this video, we explore how modern Linux distributions are transforming the computing world and why millions of users may switch to Linux in the coming years.
Advanced (Blivet-gui) on Fedora 44 Server vs Calamares
Blivet GUI is an advanced graphical storage and partition management tool for Fedora, providing a user-friendly interface for the backend storage library used in the Anaconda installer. It acts as a more powerful alternative to GParted, allowing users to create, modify, delete, and encrypt storage devices (LVM, Btrfs, RAID) with a staged, "apply-on-demand" approach.
Running Archinstall and Post installation LVs reconfiguration step via remote SSH connection
Remote connection via ssh is significantly more convenient for cut and paste all set of LVs resizing, creating, removing commands along with fstab's updates then typing all of them manually during local Arch Linux Instance setup with more or less complicated LVs updated layout .
Another LVs reconfiguration on ArchLinux as of 03/07/2026
Create root and home LVs as suggested by system during "archinstall" run-time . In general, we follow approach proposed in https://www.dwarmstrong.org/install-lmde-with-custom-lvm-luk... a while ago for LMDE 6. Upon completition drop to root's shell and update default LV's layout as shown below ( just for instance ) .
A FRIGHTENING Episode: systemd, Rust, and KDE Plasma Abandoned | Source Code #7
Too many interesting and relevant issues are touched upon in one short video and in particular the issue related with KaOS decision to transition away from systemd to regain independence and control over the core of its operating system.
Switching location of default libvirt's pool on Debian forky
Google's AI Assistant brief report some times shows up the command following below : If you need to redefine, use virsh pool-define-as --name default --type dir --target /new/path/libvirt/images, some time skips it. However, "Dive deeper in AI mode" always point to this command. Same procedure may be also performed via Virt-manager GUI with option "preferences" => XML editing enabled and manually editing path to default pool and restarting daemon libvirtd.
Setup CachyOS Kernel 6.19.3 on MX25.1 KDE Edition (VENV)
MX Linux consistently tops DistroWatch because it is a highly capable, lightweight, and user-friendly Debian-based system that appeals to a wide range of users.
Build CachyOS Kernel 6.19.2 on Debian forky (VENV)
Start with Pre-installation step $ sudo apt install build-essential bpftool and include /usr/sbin in system $PATH variable.
On Debian forky installation of libdw-dev and build dependencies for libdw-dev steps are required to succeed with build CachyOS 6.19.2 Kernel on top of Debian Testing ( forky native kernel 6.18.9 )
Stress test Deepin 25.010 via build CachyOS Kernel 6.18.7 (VENV)
Because Deepin is Debian-based, we would use the linux-cachyos-deb tool provided by the community to generate compatible .deb files. See for instance https://itsfoss.com/news/cachyos-kernel-builder/ . Notice also that current Deepin's modules names and dependencies appear to be the same as on Debian 13.3 at least during attempt to setup KVM Hypervisor, Libvirtd service and related tools as virt-manager.
Setup Arch Linux KVM Guest via archinstall 3.0.15-2
Following below is an attempt to deploy Arch Linux KVM Guest via archinstall 3.0.15-2. Load Guest via virt-manager into spice console. Pre-install archinstall 3.0.15-2 seems to be needless. However, straight forward run `python -m archinstall` having git clone done and skipping first upgrade didn't work for me .
Bring CachyOS Cosmic DE along with kernel 6.18.2 to Arch Linux Bare Metal Instance
Following below is procedure which allows to install on Arch Linux CachyOS v3 repositories along with pacman fork belongs to CachyOS. Re-sync of v3 repos and core and extra works pretty stable ( u; sudo pacman -Syyu ) - the same commands as described in post after first reboot Arch Instance into CachyOS kernel. I also have to confirm that Re-sync might be randomly required. The hack step below is scp cachyos-rate-mirrors script from remote native CachyOS Instance to the target one.
Bring CachyOS's KDE Plasma 6.5.4 along with kernel 6.18.1 to Arch Linux Bare Metal Instance
Several times schema proposed in https://lxer.com/module/newswire/view/358937/index.html has been run with no issues on bare metal . Re-sync provided by function u() embedded in /.bashrc was tested successfully on bare metal multiple times
Bring CachyOS KVM Hypervisor along with KDE Plasma 6.5.2 and Kernel 6.17.7 to Arch Linux VM
This post is an immediate follow up for Fedora 43 KVM Hypervisor && bring CachyOS KDE Plasma 6.5.1 along with kernel to Arch Linux VM ( https://lxer.com/module/newswire/view/358937/index.html ) It is quite clear that there is a way to automatically start services virtstoraged, virtnetworkd, virtqemud, virtnodedevd on Arch Linux VM , however I was not lucky enough to automate this procedure.
Fedora 43 KVM Hypervisor && bring CachyOS KDE Plasma 6.5.1 along with kernel to Arch Linux VM
Following below is procedure which allows to install on Arch Linux CachyOS v3 repositories along with pacman fork belongs to CachyOS. Proceed as advised in post on Arch Linux KVM Guest deployed via F43/42 KVM Hypervisor . Upgraded Arch Instances have successfully passed via `sudo pacman -Syyu` multiple times during several recent days.
Attempt Arch Linux LVs reconfiguration in Post-installation phase
Following below is an attempt Arch Linux LVs reconfiguration in Post-installation phase. Original LVs layout configuration cannot be changed during archinstall active state. After archinstall finishes up we are going to switch to terminal session via "exit" option rather then reboot .
LMDE 7 LV Setup per Daniel Wayne Armstrong (VENV)
Setup below in general follows guide lines proposed in https://www.dwarmstrong.org/install-lmde-with-custom-lvm-luk... However, we intend to remove swap LV and increase sizes of root and home LVs . Then reboot system and activate zram instead of keeping unreasonably large LV swap on /dev/vda .
Deployment Fedora 43 Cosmic Spin as KVM Guest per Google's Dive deeper in AI Mode guide lines
Tuning Virt-manager you are supposed enable 3D-acceleration and OpenGL to avoid crashing instance setup and successfully install Fedora 43 Cosmic Spin in VENV. The interesting thing is that F43 Cosmic Spin behaves the same way on bare metal and as KVM Guest. No issues for switching between different folders contain wallpapers for Cosmic DE happens in VENV.
