I'm on linux mint 20.3, based on Ubuntu 20.04 I believe. Great if it's already fixed elsewhere.

The main pain point for me is interleaving within a line, and these workarounds don't fix that issue. Can something be done about that? Eg line buffering?

That is pretty annoying. The simplest solution (and probably the only one that makes sense for larger process counts) is to do all the printing on process 0. The problem...

Oh I need it too and was pleasantly surprised to see that it worked. The thing is the `size` method: should it be undefined, or perhaps check that the sizes...

> size is useful in a lot of cases Thought so too but probably it's a code smell for generic code that doesn't assume much about array types. It's only...

Great to see this taken up! I wanted to do it at some point but was waiting on @pkofod 's fabled rewrite :-) > Should Optim.retract! calls not rather always...

Do you mean that you have two mathematically well-defined retractions and one performs repeatedly and noticeably better than the other? If so I'd be interested in that. Are you sure...

That's not contradictory with what I said: mathematically (in infinite precision) both are equally fine, but of course you have to take care to implement them properly (stably). I'm pretty...

Ie: you have to distinguish the mathematical function and the algorithm implementing it. For me "retraction" only refers to the former

I don't understand at all why you would say that. There's nothing sacred or "correct" about the exponential map. It's just a canonical (associated with a specific riemannian metric) way...
