Hetzner, OpenBSD, IPv6
I like Hetzner Cloud a lot for small projects that just need to work or for machines that have a short lifespan, for experiments and whatnot. It's comfortable, cheap and gets the job done. I don't expect much for roughly three bucks a month, but so far the service quality has been exceptional – no downtime, no hassle, nothing.
Unprivileged LXC-containers on Debian Stretch/Buster
In an ideal (from a capitalist point of view) world I'd come to work every morning and spend eight hours hunched over my desk churning out mails, reports, documents, code, case files – whatever.
Windows, OpenSSH & keys
Since the end of 2017, Microsoft offers native OpenSSH-functionality in Windows 10. And while PuTTY has accompanied me for a number of years, I'm not exactly sad to finally get 'the real deal', so I can painlessly pretend I'm being productive while I'm on Windows (No, that's not a game you see minimized in the taskbar. Move along, peasant!).
