Free Software & system developer
Greetings, user of the internet. Welcome to my little website, where I put an information about myself and my projects.
The name’s , pronounced . Out of many things in this world, I admire technology, collaboration and freedom the most!
Currently an independent software engineer and an employed system administrator. Have been practicing programming and other fun computer science stuff for 4 years! My continuing mission is exploring strange new technologies, seeking out new systems and new ideas, and…
…boldly coding what no one has coded before.
Self–learner and independent thinker. Day by day, I strive to make this world better by spreading greatest open technologies, engineering culture and good team spirit.
Essentially, whenether I’ve got a exclusive idea and I think I’ve achieved something pretty cool, I write new pages here. I always try my best to write detailed, dense, but at the same time accessible and straight to the point texts with a balance of practice and theory. If you like science, researches, adventures and stories — welcome to my articles. If you like engineering, software architecture and development — my projects could be interesting for you. Either way, I hope my posts will inspire you to explore technologies as well!
Of course, there is another stuff here. You can:
Tailscale is a very simple and convenient VPN software. You can get a control plane, clients, routes and exit nodes with it in less than an hour without caring at all about how keys, routing or relays work. But what if you need to implement a network policy, for which Tailscale doesn't have an established interface? This article presents an example of how to implement PBR, knowing how Tailscale routing works.
Single-board computers are often used as Linux servers. Raspberry Pi 4, for example, has enough system resources to run multiple applications in parallel. Often, these applications are run separately on different VMs or containers, in order to enhance security and maintainability. This article shows a way to set up your Raspberry Pi as a Linux container host and a hypervisor.
Gap buffer is one of the most common data structures used for editing text, while a dynamic array is the simplest data structure for manipulating a sequence of elements of arbitrary size. What is the most optimal choice for an application that not only does text editing, but redraws the entire line on every key press? In this article, we'll find out.
A Linux kernel module written in C. Creates a special character device that, when being read from, outputs every created or deleted file on the entire system. It does so by intercepting system calls. My first Linux Kernel module ever developed. Not very practical for use, because Inotify exists.
My personal website that you are watching right now. A place for my thoughts. A place to tell about my skills, projects and share information that I, from a developer perspective, find useful and interesting.
An STM32F103C6T6 microcontroller firmware. Textual information goes to the USART pins on a microcontroller, while Morse signal is on one of the digital pins, for example, connected to LED. Sending ASCII letters through USART will make an LED blink accordingly to the decoded Morse signal, and otherwise. It is my first firmware made with Zig programming language, and it serves as a great example of a simple, interrupt-driven application.
