Install Windows 11 as KVM Guest in Fedora 38 WKS using virt-manager

Brief instruction for setting up Virt-manager to perform straightforward installation of Windows 11 KVM Guest on Fedora 38 Workstation under 6.3.4 kernel.

Install Virtual Box 7 on Fedora 37 Server via rpmfusion repository

To make system ready for VitualBox 7 setup via rpmfusion repos,install the Linux kernel "header" files matching the current kernel for adding new hardware support to the system. The distribution packages containing the headers is probably: kernel-devel-6.0.9-300.fc37. Kernel packages installation has been done as follows.

Central limit theorems (CLT) are a class of theorems in probability theory stating that the sum of a sufficiently large number of weakly dependent random variables that have approximately the same scale (none of the terms dominates, does not make a decisive contribution to the sum), has a distribution close to normal.

Uploading dictionaries into SQLite tables via Pandas DataFrames on Python

The following below is a not entirely trivial algorithm for students that creates a Python dictionary after scanning text according to the conditions of the problem, which gets converted into Pandas Dataframe and uploaded to SQLite database table to be analyzed via nested SQL Query.

Exersing Python 3.10 on Fedora 25 via sorting Pandas DataFrame

The following below is a not entirely trivial algorithm for students that creates a Python dictionary when scanning text according to the conditions of the problem, which is then processed as Pandas Dataframe to provide the output required

Python Wrapper to find all primes from a given interval via sieve of Eratosthenes released in C++

We intend to rely on https://github.com/mathbunnyru/python-cpp-extension . We also would convert lists to sets and vice-versa and utilize method set1.difference(set2) . Sometimes Python tricks make you really excited

Python Wrapper for sieve of eratosthenes released as C++ procedure (YandexQ question)

This post is an immediate follow up for http://lxer.com/module/newswire/view/306255/index.html what will result significant performance boost vs python's version of the sieve of Eratosthenes procedure.

Solution another YandexQ question via sieve of eratosthenes in Python

The major target of this approach is performance improvement when looking for the highest prime number less than 10.000.000 with a given sum of decimal digits. The problem requires implementation of sieve of Eratosthenes

Attempt to test Web Cockpit Console on Fedora 35 Beta Server (VENV)

First - Fedora 35 Beta Server deployed as L1 KVM Guest on F34 Bare metal Server . Nested virtualization enabled via virsh console on F34 Server. Complete KVM && Cockpit install performed on L1 F35 Server Guest per https://computingforgeeks.com/how-to-install-kvm-on-fedora/

111+ Linux Statistics and Facts – Linux Rocks!

Back in the year 1993, Linus Torvalds walked into a bar. He saw a lonesome cowboy about to mercilessly dig into a bowl of kernels. The cowboy said:Mmmmm, those kernels are the best… And that’s how a new operating system was born. Not with 10,239 lines of code, but with a kernel. True story!

Set up Virtual Box on top of Server F35 (pre release) via rpmfusion (VENV)

First I've installed the most recent nightly build of Fedora 35 Server on Fedora 34 Bare metal KVM Virthost as Guest OS with "Fedora Workstation" desktop, like virtual machine seating on the Linux bridge been created via Web Cockpit Console. When done issued the following set of commands on F35 Guest

Python (numpy && matplotlib) solving one relatively difficult math problem

The problem itself is to find all solutions of the following equation on the real axis - cos (cos (cos (cos (x)))) - sin (sin (sin (sin (x)))) = 0. We intend to prove that equation above doesn't have any solution via creating a python script importing NumPy and Matplotlib.

Deployment KVM Guests via Cockpit Console on Manjaro KDE 21.1.2

I am posting this Howto due to currently available instructions on the Internet don't focus the user's attention on installation packages "ovmf" and "virt-viewer" on the most recent release Manjaro KDE. Skipping mentioned packages causes issues with Remote Viewer (Cockpit Console) and the ability to deploy KVM guests in UEFI mode

Set up KVM && Cockpit WEB Console on Debian Bullseye (11)

The presence of Web Cockpit Console is a nice way to manage KVM guest's deployment via clicking the button "Remote Virt-viewer" built into Cockpit Web Console. Bridge attached to external network interface was also created pretty smoothly utilizing network management section inside Web Console. However, it doesn't look to me as a reason to deprecate virt-manager .

Set up KVM && Cockpit WEB Console on Ubuntu DDE 21.04

First notice that we intend set up Ubuntu DDE on Ryzen 7 3700 box with board MSI X570 A-PRO in UEFI mode with "kvm" enabled. Enable SVM in the BIOS Setup due to it is disabled by default. This step might be the hardest to complete in the whole installation procedure.

Setting up KDE Plasma on Rocky Linux 8.4 KVM/VBOX-6.1.26 Guest on Server F34

Following below is a brief set of instructions setting up KDE Plasma on RockyLinux along with Gnome Desktop Manager which is actually needed to support graphical login, otherwise system might be started via text login followed by "startx". The core idea is to install and activate just GDM to make graphical login enabled on Rocky Linux 8.4

Install Sqlitebrowser on RockyLinux 8.4

Following below is a brief set of instructions to install sqlitebrowser on RockyLinux 8.4 , which installs sqlite-devel before building the most recent Python release via source tarball

Python Wrapper for C++ solving the recent YandexQ problem

In this post I follow approach suggested in How to wrap a C++ object using pure Python Extension API which differs from C++ coding technique been presented earlier. Public Class Strike containing method "filter" is supposed to be declared. Later on in PyStrike_init( ) new instance of this class is been created.

Armadillo matrices via NumPy array and Python Extension to C++

The core test is converting numpy array into matrix 5x5 in Armadillo C++ inversion matrix into matrix C and verification myMat * C = E , afterwards we can safely return matrix C to Python Runtime Module

Assembly of Python External C++ procedure returning the vector of strings objects

This post is an immediate followup for the most recent post at Lxer.com regarding return of one string. Consider the task already been treated with 2D vector and dumping the content of vector to disk file. This approach would allow us to solve the same task via to straight forward returning vector of strings from C++ procedure to Python module.
