Is something wrong with caches "on the Internet" lately?

I am doing

ssh user@host

and it hangs. I need to Control-C it and try again, then I get a prompt for a password.

GitHub is having more and more troubles rendering Jupyter notebooks, and even the simplest notebooks sometimes require multiple reloads.

The alternative method of rendering Jupyter notebooks, via nbviewer.jupyter.org/

is also having the weirdest cache-related issues between it and GitHub (I was adding my complaints to github.com/jupyter/nbviewer/issues/979 in recent months on a regular basis).

WTF is going on? Is it that software engineers decided to pretend to be "effective managers" and are setting timeouts too tight and are invalidating some caches too fast trying to save some pennies?

Sparsity in Neural Networks (first workshop with this title)

I am very interested in sparsity in neural nets and I am super-happy that the community around sparsity is growing, and the first workshop on the subject had just taken place.

The key organizer is D.C.Mocanu; I did an experimental PyTorch project building upon his work a couple of years ago.

I learned about this via the ML Collective reading group mailing list. The links are in the comments.
