Earlier this week, I visited Nkozi, home to Uganda Martyrs University (UMU) to speak with IT & science students about #OpenSource software. Their passion & energy was inspiring!

Thanks @opensuse.org for the swag & to UMU for the hospitality. The future is open!

Really enjoyed openSUSE Conference 2025 in Nuremberg! A standout was Tropic Square's hands-on session
featuring TROPIC01, the 1st open &
auditable secure element. Big thanks for the devkit & great insights on hardware security for #Linux, edge, and secure infrastructure.
