📍 Belgium | 🛠️ Co-founder of Oh Dear | ✍️ Blogging at ma.ttias.be since 2008
I've been writing about Linux, PHP, DNS, and SSL/TLS for longer than I remember. These days most of my time goes into Oh Dear, the website monitoring service I co-founded. The rest tends to end up here: small PHP packages, Varnish configs, sysadmin tooling, and the occasional thing I built just to prove a point.
