I'm doing remote work for decades, so nothing changed but the lunch menu. Now I have to cook by myself. I always worked via laptop, and only for massive tests need to use the big machines. Most of them locally, as being independent is far superior. Most stuff is open source, do I can use public CI's and trackers.

Working remotely is also far more productive as there are zero interruptions to your workflow. I would say twice as much. Unfortunately you'll also do more hours, because it's so much more productive, so beware to stop. Time to think and reflect is important, and you might forget that. Turn off slack, irc and similar notifications. Check email only twice a day, it's a huge timesink.
