Kali Linux Commands: Essential Guide for Penetration Testing
Kali Linux isn’t just another Linux distribution. It’s a specialized operating system built specifically for security professionals, ethical hackers, and penetration testers. The real power of Kali Linux lies in its command-line tools. Over 600 security tools come pre-installed, each designed for different phases of penetration testing. Learning the essential Kali Linux commands transforms you […]
Types of Shell in Linux: Understanding Your Command Line Options
When you open a terminal on Linux, you’re conversing with a shell. That’s the program sitting between you and the operating system kernel, translating your commands into actions the system understands. Different types of shells in Linux exist because developers have different needs and priorities. Some Linux shell types prioritize scripting power, others focus on […]
The Linux wget Command – Linux Download Command
The Linux wget command is a command-line utility that downloads files from the internet using HTTP, HTTPS, and FTP protocols. It’s designed to work non-interactively, meaning it can run in the background while you’re logged out—making it perfect for retrieving large files, automating downloads in scripts, and handling unreliable network connections. Most Linux distributions include […]
Soldering Workshop in Mathematics and Science High School (PMG) in Pazardzhik

Name that Ware, November 2025
The Ware for November 2025 is shown below.
This one is hopefully a bit easier to guess compared to last month’s ware! Pictured is just one board of a two board set, but the second board is a bit too much of a dead give-away so it’s been omitted. Thanks to Sam for thinking on her feet and snatching this board so that it could be donated to the contest!
Winner, Name that Ware October 2025
Last month’s ware is an ADAS1010, described on the Analog devices website as a “15 Lead ECG Vital Signs Monitor Module with Respiration, Temperature and Blood Pressure Measurement”. It advertises a “robust, with electromagnetic interference (EMI), shock, and vibration resistant packaging”.
This is one of the more over-engineered solutions I’ve seen. I’m guessing that the middle layer of the three-layer stack is probably hollowed out, such that the surrounding boards create a Faraday cage. This would allow sensitive ECG front-end circuitry to be placed inside a shielded “container” that also doubles as a connector between the front and back boards.
This one...
Кустарные вакуумные триоды Клода Паяра. Часть 3. Установка ТВЧ
Продолжим обзор оборудования французского коллеги-энтузиаста Клода Пайяра, с его самодельным кустарным мини-производством триода ТМ [1] — первого серийного высоковакуумного прибора 1920-х годов, с невысокими (относительно прежних «ионных» газонаполненных ламп), но так нужными пользователю, стабильными параметрами. В части №1 мы познакомились с самим Клодом и его огневым оснащением, в части №2 рассмотрели простую технологическую мини-печь для отжига стеклянных деталей и аппарат для контактной сварки. Здесь же, мы взглянем на его установку ТВЧ — её создание и настройку.

«...Одним из примеров громоздкой и, по мнению авторов, бесполезной надстройки является интегрированная система WINDOWS фирмы Microsoft. Эта система занимает почти 1 Мбайт дисковой памяти и рассчитана на преимущественное использование совместно с устройством типа "мышь".» — вы точно знаете, откуда это
Приветствую всех! Буквально неделю назад прошло сорок лет с момента выхода первой релизной версии Windows. Именно в тот день в 1985 году началась история ныне повсеместно распространённой ОС.
И вот, узнав об этом, я подумал: а что, если попробовать запустить эту ОС и узнать, как предполагалось писать софт для неё? Именно этим мы сейчас и займёмся. Заодно и узнаем, насколько это было...
Nvidia Graphics Cards work on Pi 5 and Rockchip
Nvidia Graphics Cards work on Pi 5 and Rockchip
A few months ago, GitHub user @yanghaku dropped a 15 line patch to fix GPU support for practically all AMD GPUs on the Raspberry Pi (and demoed a 3080 running on the Pi with a separate, unreleased patch). This week, GitHub user @mariobalanica dropped this (larger) patch which does the same for Nvidia GPUs!
I have a Raspberry Pi and an Nvidia graphics card—and I'm easily distracted. So I put down my testing of a GB10 system for a bit, and...
