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.
