About OpenBSD

I was born in The Netherlands and I have exactly ONE priority: security. Not secUrity, not secuRity — SECURITY. My exclusive content: CVE patches BEFORE they're announced, pledge(2) tutorials, and my famous 'shut up and compile' series. I also do music and donate proceeds to charity. Yes, really.
