Learn Linux before Docker, Kubernetes and AWS.
They are derived technology from the OS.
And you'll understand them deeper by knowing Linux.

Anyone using #Proxmox on #Scaleway with Private Networks + Public Gateways? After live migration, I’m seeing weird ARP issues—TCP window size spikes and download drops below 100KB/s. Support is helpful but slow. Anyone else run into this?

The saga continues. Moved from OVH to Scaleway for my personal servers. A bit more expensive, but generally better support for private networking on bare metal. At least for the cheapest servers. Working great with proxmox. Might add another node to be able to setup ceph. #eu #proxmox #nix

I’m looking for a fast, easy to configure and lightweight #DNS server that supports #DNSSEC. Preferably something that can run out of the box on #nixos. Any recommendations?

Migrated my services from #Vultr -> #Hezner -> #OVH in just over one week. Hopefully I’m done switching providers now. Dedicated servers on OVH are really cheap. Running with #proxmox which gives a lot of possibilities.

Just migrated my webpage from my (over-engineered) Rust application to #gohugo. I was already using Markdown files for posts, so the migration took about an hour from installation to finished «product». Now using the #PaperMod theme. Easy-peasy.
