It's very tightly integrated with Sage. It's also written in a pretty old style (using a lot of html and jquery), and I plan to rewrite it soon, since it's one of the only things left in CoCalc that isn't written in Typescript/React. Sage worksheets are implemented entirely separately from the Jupyter stack, not even using the Jupyter kernel for Sage (instead, they have their own backend server process, which uses fork each time you make a new connection, for faster startup). They do have a way to easily create any number of connections to different Jupyter kernels, and use them all in the same worksheet. I wrote Sage worksheets mainly 2012-2014, and have maintained them ever since, because they are pretty popular on CoCalc, e.g., they just use a normal single document editor interface, rather than a "weird" modal interface with many little editors like Jupyter notebooks, and some people find the Sage worksheet approach more natural. One nuisance of Sage worksheets is that the exact version of Sage isn't specified anywhere in the file format -- it just uses whatever "sage" is in your path. Jupyter is better in this regard. Jupyter notebooks = of course we all know what they are. I'm personally a huge fan of both, but they are very different. I hope I can unify the two approaches sometime soon, so that there's a mode for using any Jupyter notebook that looks like a Sage worksheet... and so the custom Sage server mentioned above is just a different Jupyter kernel (maybe called "cocalc-sage"). > > john perry > > On Sunday, June 20, 2021 at 1:15:28 PM UTC-5 ingo...@gmail.com wrote: > >> That looks great and I am looking forward to reading it more in detail. >> Just two quick questions to get started. >> Is this also published on CoCalc? >> Why do you prefer the use of Sage Worksheets over Jupyter Notebook? >> Best wishes >> Ingo >> john_perry_usm schrieb am Sonntag, 20.
