I’m into open-source firmware, drawing inspiration from the classic hacker ethos of collaborative innovation and transparency. At 3mdeb, we’re excited about our two main projects: Zarhus OS, an Embedded Linux distribution based on Yocto, and Dasharo, a coreboot downstream. Both are about the value of open development, embedded firmware resilience, platform security transparency, the right to repair, and digital sovereignty.

Community is at the center of our activity. By being involved in the Dasharo Users Group, Dasharo Developers vPub, and events like the Qubes OS Summit, we connect with others who share our passion for open-source. Our efforts with OpenSecurityTraining2 reflect our commitment to sharing knowledge and improving the open-source firmware ecosystem.

As the founder of 3mdeb, my daily tasks go beyond managing the company. I am also responsible for making important decisions about our products, such as Zarhus OS and Dasharo, and developing valuable processes that establish a foundation for projects we undertake for our clients.

Outside work, I enjoy simple pleasures like chess, bridge, and reading. Nature, especially the peace of the forest, is where I find solace. My interests in theology, philosophy, and psychology keep me curious about the world. Whether it’s exploring new technologies or understanding complex ideas, I’m always eager to learn and grow.

As I wrote in previous post I switched from GNU screen to tmux. I use it for a few moths and have to said that I’m really impressed by simplicity, performance and community support in this project. In this post I want to discuss my configuration and useful additions for it like tmuxinator, session logging, colors or status bar configuration. Basics Debian contain tmux package but for stable and testing release it is pretty old version....

How to begin with coreboot

Published at January 6, 2012 ·  1 min read

About a month ago I started my adventure with coreboot. As coreboot home page says “coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers”. Although I read the majority of materials from mentioned page I still suffered from a lack of basic information that would help me to arrange everything in my head. Therefore, I decided to write a series of posts described my actions associated with this interesting project....
