I’m one of the founders of Nextjournal and I’m really excited that after almost three years in Private Beta we’re finally opening signups to everyone today!

Nextjournal is a computational notebook platform and our goal is to make computation more accessible and automatically reproducible, so it becomes easier to collaborate and build on top of each others work.

If you'd like to know more, check out our launch blog post at https://nextjournal.com/mk/public-beta or sign up and give it a try!

Hey,

just had a very brief look out of sheer curiosity, so please take this quick feedback with a grain of salt: The running times of your Python notebook get longer and longer with each print() statement and cell. While the reproducibility of your python notebook is a wonderful thing to have, I think the performance decrease is very strong downside.

Cheers -

Hey, this sounds like something we'd want to look at, I don't think it's inherent to reproducibility. I think we should be truncating the output in this case. Please send us the notebook via the Help button that shows up when you produce an error in a cell, I'll take a look and we'll figure this out.

Just signed up hoping for scala but it wasn't there.

Is that something you would be looking at adding?

Yes, we certainly want to support a lot more languages in the future and it should be relatively easy to do as long as there's a Jupyter kernel (which is a lot).

We also have a proof-of-concept PR where you can implement a runtime in a notebook.

I think we'll expand the available languages as soon as we're confident the core product really solid.
