Anti-DEI is white supremacy. Black lives matter. LGBT+ rights are human rights. Healthcare, security, a decent income, and housing with dignity are human rights. Abortion is healthcare. Science is our best hope as a species. Kindness and empathy are the noblest of human traits.

No alt-text = no repost.

I block assholes and bigots.

I love open source. Information Security is important to me. I am a beekeeper, a photographer, a gardener, a radioamateur, a woodworker and sometimes I work on Icecast in my free time. I have many projects and a black belt in partial arts.
