Dennis Krul

I'm director of operations at a hosting company, responsible for the teams and the roadmap behind its servers, storage, virtualization, networking and datacenters.

I engineer software, but I wouldn't call myself a software engineer: I build things to make computers do what I want.

My job is no longer hands-on, so I tinker at home and try to keep up with new tech.

My main project right now is EMS, the energy management system for every energy flow in my house: solar panels, home battery, car charger and heat pump. Its stats are on the EMS page, and the Dutch electricity prices it works with are under Energy.

I care about digital sovereignty. I've always been an open-source and self-hosting guy: I'd rather fix my own things, own my data and keep it private than depend on someone else.

That doesn't make me against SaaS or commercial software, but I'm always looking for the free alternative, free as in freedom. Open source is about community and freedom, not just published code, which is why I'm still waiting for a real Linux phone.

Away from the screen I make and mix music: house, techno and some trance. I started DJing on old turntables at fifteen and making tracks in ModEdit, then Scream Tracker 3, FastTracker, Renoise and Ableton, and now Bitwig Studio on Linux.

After 25 years I sold my Technics 1210s for a digital setup, only to find that beat sync makes DJing a bit too easy. So these days it's more about making music, and one day learning to play keys properly.
