I donate to Ladybird and Servo, and I hope they succeed. We need serious competition and a check on Mozilla (not to mention Chrome and Safari).
That said, I’m sad that neither Ladybird or Servo are licensed under strong copyleft licenses. We need user-oriented browsers now more than ever, and strong copyleft enables that. I worry that, even if these engines are successful, they will be co-opted by proprietary browsers and eventually superseded by them.
This happened before - both Chrome and Safari ultimately derive from KHTML, Konqueror’s browser engine. If KHTML had been licnesed under the GPL instead of the LGPL, Chrome and Safari (and not just their engines) may have been free software today. Or, at the very least, it would have been much more difficult for Apple and Google to get started.
That said, I wish Ladybird the best. There donation = no influence policy is excellent, and I really, really hope they can stick to it in the long term.
For services only I depend on, I have production-only. Since I can only inflict damage on myself, and can often work around problems.
For the XMPP server my friends and family also depend on, I have a dedicated nonprod VPS. My services are driven by ansible playbooks, so I’ll tweak the playbook with whatever change I want to make works in nonprod, before running the same playbook against prod.
Whenever there’s a new Debian Stable release, I’ll rebuild the servers completely, to try and prevent “drift” between the nonprod and prod versions (not that I change things often enough for this to become a big problem). This is also the big test of my backups, which so far haven’t been needed in a “real” emergency 🤞
