Do you know about Electric SQL (https://electric-sql.com/docs/overview/technical-intro)? It sounds similar to what you describe.

At my university we also use Matlab a lot. However, I've found that Octave is a very suitable replacement for all packages except Simulink, which is widely used for Control. The alternative here would be Scilab/Xcos.

I also use python/sympy/matplotlib/scipy/jupyter a lot and it's absolutely great -- highly recommend to the OP.

I also understand it to be read only. Any reason why screen or tmux session sharing can't handle your use case?

On-topic: Great 2.0 release! Asciinema is great software for tutoring or showing off a terminal app, I use it a lot!

Enter rolling distributions, where each upgrade is guaranteed to work. Even if you can't upgrade from version A to C, you can upgrade from A to B to C. Why can't Microsoft products also upgrade this way, even between major versions?

e.g. Docker, too.
