I've been using mailbox.org for 5 years and like it very much. Cost some 3 EUR per month (actually there's a 50% discount this week).
Dead simple email that just works. Their webUI is fine, but I almost exclusively use it on iOS or macOS with the default mail app. They also have some other features (calendar, office suite, video calls) that I don't use. I really like the option to create up to 25 email aliases.
First, congrats on the release. I’ve looked at flox and devenv for nixifying our container builds. Our distribution of languages is about 40/30/20/10 of Python, F#, R and nodejs.
A dilemma I’m facing is that the win from nix in terms of faster builds and smaller images would be largely from python and R images (where the average size is often 1Gi or larger). However, the developers that use Python or R are less likely to “get” the point of Nix and might have a steeper learning curve than F# developers (where the builds are quite efficient).
That was the context, my question is, how’s the integration with Flox and R/RStudio? I know there’s Rix[1] for managing R packages with Nix.
