I started making YouTube videos covering Linux content when I was 14. I would eventually volunteer for Pine64 making their community update YouTube videos and went on to work for TechHut Media at age 17. I also built risiOS which innovated on top of Fedora by making it more user friendly thanks to friendly onboarding, and experimenting with custom features such as rTheme, our custom theming engine. Since I have merged risiOS with Nobara Linux. I have been working on stillOS, a new concept combining rpm-ostree with web app integration, a curated app store, and the user friendliness of Zorin OS.

Timmy James Barnett is passionate about the philosophy of FLO (Free/Libre/Open) software. He is happy to be using GNU/Linux and FLO software he wrote for his performances with GNU/Linux Loves All and !mindparade. His music is inspired by FLO technologies including GNU/Linux, Matthew Autry's skip-fretting, Kite guitar, and Jim Snow's mosaichord. These technologies have connected him with older notes that have been covered up by modern standard tuning. Rather than being limited to just one tuning, Timmy's music is inspired by both the harmonic series and various edos beyond 12edo (known as standard tuning). He finds a unique sound from the intersection between ancient tuning theory, modern music technology, and a FLO philosophy.
