Self-hosting the services people rely on

This section is about running the everyday services people depend on — files, mail, collaboration — on infrastructure I operate, rather than renting them from a large provider.

Self-hosting is not nostalgia. It means the data stays where you can point to it, there is no third party mining it, and when something breaks you can actually fix it. It also means you carry the complexity yourself: keeping a collaboration platform healthy, running a mail stack that the rest of the internet trusts, and monitoring all of it so you hear about a problem before your users do.

What I write about is the operational reality: the tuning that made a service stable, the upgrade that went sideways, the small configuration detail that mattered far more than it should have.

Expect posts on Nextcloud, mail operations and monitoring. Honest about the work involved, because pretending it is effortless helps no one.
