I would like to say that we (we = the most part of French mathematicians) want to develop a computing facility based on Jupyter (jupyterhub, actually). For this, we will use a cluster of "second hand" machines (a cluster of machines which have been used some years for parallel computations (with an infiniband network, ...)) and convert them to a jupyterhub cluster. This is not aimed only for running sage, but also a lot of python things, R, julia and so on
(yes, I know, we can run most part of this in Sage; but not all). So, using sage with jupyter is crucial for this project.

The rationale is that the Sage notebook is in "maintenance mode" while the Jupyter notebook is actively developed, and becoming a standard much more widely than in the Sage community, with now ~50 kernels available and many projects using it, see https://github.com/ipython/ipython/wiki/Projects-using-IPython https://github.com/ipython/ipython/wiki/IPython-kernels-for-other-languages Since SageMath will eventually use Jupyter notebook by default, why not let our new users discover it first. > Does one need to use "from sage.all import *" or is Sage a "kernel" > for Jupyter now?

Running sage -n jupyter starts a Jupyter notebook server. You can explore the file hierarchy (starting from the directory where you launched the above command), and when you click "New" you can choose between "Python2" and "Sage" for creating a new Jupyter notebook. > (I would have thought that switching to the "personal" SMC would be > the more evident new default, though that is a much bigger project > and SMC isn't really a notebook in the usual sense anyway, > that's just part of it.) When you launch a Jupyter notebook in SageMathCloud, it starts with the Python2 kernel. You can then use the menu "Kernel > Change Kernel" which currently lets you choose from the following kernels: - Anaconda 3 - Julia - Python 2 - Python 3 - R - Sage 6.9 - Sage 6.9.beta7 -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
