I note that I can use SageMath 8.9, and request it in Dockerfile to run a notebook from CoCalc, but then the user still has to manually select the kernel on binder launch. I did not find out how to launch a notebook with octave kernel.

It might be useful to desccribe in ReadMe what are the available kernels and how they are to be requested in Dockerfile

I was curious to see whether the new conda package for Sage would enable the deployement of SageMath Jupyter notebooks on mybinder. That would be a really cool feature.

It seems to go a long way. However building the mybinder image currently fails during the installation of conda packages:

Any clue?

A youtube video embedded into a markdown cell in a Jupyter Notebook in Cocalc is not shown when displayed in Binder. It is shown in Cocalc and in the static nbviewer page.
Also other pages embedded through iframes are shown as blankframes with an empty html document as content.

I tried to install a package, sirocco, and I got this.

Step 17/24 : RUN /sage/sage -i sirocco
 ---> Running in 8c950112eff7
/sage/src/bin/sage: line 226: /sage/build/bin/sage-site: No such file or directory

After commenting the line of installing I checked that the folder build does not exist. Without installing the package, it works really nice and fast. Best, Enrique

https://mybinder.org/v2/gh/sagemath/more-sagemath-tutorials/master?filepath=_build/html/tutorial-start-here.ipynb

errors out.

I have been working on enabling CircleCI/GitLabCI in the sagemath repository. As one application, I am now playing with automatically setting up sage-binder-env branches from CI for every build. My idea is that this could allow people to include a "launch on binder" badge on trac tickets so that code changes can be tried out by reviewers without actually having to build the code.
Have you considered such an application? What do you think about it?

I have a Jupyter Notebook with Sage kernel exported from Cocalc in a github repo. I copied the Dockerfile from this repo into my repo https://github.com/ingodahn/Linearkombination.
When I launch Binder I get an Internal server error 500.
Any further hints?

I am rebooting sage live doc efforts

sagemath/sage#36144

Reported by @marcinofulus. When plotting in 3d, these urls (and possibly more) give 404s:

• /hub/nbextensions/threejs/three.min.js
• /hub/nbextensions/threejs/OrbitControls.js
• '/hub/nbextensions/jsmol/JSmol.min.js`

The files seem to be correctly symlinked in /home/sage/sage/local/share/jupyter/nbextensions/, I haven't had time to debug yet.

ThreeJS seems to have the same problem in the SageMath version packaged for Debian/Ubuntu (JSmol is not available in Debian).

Hi Dima,

I added workflows that automatically (every day) updates the Dockerfile to use the latest (stable and develop) version of Sage.

As we refresh this repo, I thought changing the default branch name from "master" to "main" fits the trend. I added a new branch "main", which is the same with the master branch except the name.

So I suggest to change the default branch to "main". I don't have right to do that. If you disagree, it is okay too, just let me know.

Thanks for your attention.

I made several tries to work with sagemath and mybinder with no success:

• Docker with sagemathinc/cocalc:latest used to work, it does not any more for me.
• Tried also with cocalc-lite, same thing.
  In both cases basically the same error as in this post
  I tried the conda approach both the tests and one of my repos (not explained in the readme, just disable docker file and copy environment.yml. In this case binder session is opened but sage kernel is not connected. Running sage in the terminal gives the error in this other post.
