@jcoady JUPYTERHUB_API_TOKEN (and a couple other JUPYTERHUB_) environment variables will be defined on the kernel side. Maybe harder on the javascript side.

Is there a good demo notebook that walks through the features of the notebook (so I don't have to reinvent the wheel)?
Aaron Hall, MBA
@aaronchall
I'm seeing some in the notebook github repo

ipython/ipython-in-depth is the place where such things have lived for a long time, but I fear it is extremely outdated
(as perhaps evidenced by the fact that it's still an IPython repo)

I have what I think is an error on this page - I went to the 'edit on github' but I get a 404 message.

does anyone know the source of these documents

@chicocvenancio - looking for where the pages are stored on github - ie) where one can file a pull request for a text issue on the page

Petrichor 🌦️ Hey folks, is there a magic to render the entire cell contents as a jinja2 template with the currently defined variables as the context?
Petrichor 🌦️ I currently use a python cell for this but it would be a little neater to just interpret the whole cell as jinja2

hi everyone - have any of you ever worked on alert notifications using python notebook
pandas etc ?

Hi, we would like to introduce https://github.com/NII-cloud-operation/sidestickies. A notebook extension, which enables us to attach sticky notes to each cell utilizing Scrapbox https://scrapbox.io .
You may try via https://mybinder.org/v2/gh/NII-cloud-operation/Jupyter-LC_docker/sc-demo and the sample notebook "EN02_Collaborative_Annotation.ipynb" in the container. This container also includes our extensions for semi-linear notebook operations, as well.

Does any one know of a reason why c.NotebookApp.notebook_dir would not be set properly? I am setting it as /src, however, when notebooks are launched they are actually running in /src/notebooks. I have added an issue at jupyter/notebook#5072 and steps to minimally reproduce at https://github.com/guzman-raphael/notebook-dir-issue
Andreas Klostermann
@akloster
I have another strange question... Is it possible to start an ipykernel from an existing event loop? I have a working kernel that runs with FreeCAD, but it has problems. I think it would ideal to start an IPyKernel app (with all the settings and the connection file) after starting the QT App of FreeCAD. Then it would be easier to re-redirect stdout and stderr to the kernel's stream. Is there any way to do that?
Jason Grout
@jasongrout
this would be an excellent question on the ipykernel github issues. @takluyver @ivanov @Carreau or @minrk likely know the answer or could point you in the right direction.
Matthias Bussonnier
@Carreau
Probably not out of the box; you will have to subclass some things. You want to look at IPKernelApp in the ipykernel package. You likely wan to overwrite the start method as this appear to be the only thing that start an eventloop.
If you need changes for things to work feel free to send PRs.

@igormorgado
Hellow is there any way to make images show off in jupyter notebook only after a plt.show() request? I'm using RISE to build a slideshow and is annoying that all views share a portion of code in slide. IF there is a way to hide the source code in RISE is perfect too.

it should. but do not works, unfortunately.
Angus Hollands
@agoose77
@igormorgado are you using %matplotlib inline or something else?

Hi everyone, I have a question, how can I check Jupyter notebook's operation log? An important file in our Jupiter notebook server was deleted, we need to check who deleted the file and when. May you help me?

Hi! I am very sorry if this has been asked before, but I was not able to find any definitive information anywhere. Is there an (up-to-date) roadmap about the transition from Jupyter notebook to Jupyter lab? The roadmap here https://github.com/jupyter/roadmap/blob/master/notebook.md appears like it has not been update for a while, and I would be interested to know in which phase of development the project currently is in.
Jason Grout
@jasongrout
Yes, that hasn't been updated in a while
currently, notebook and lab are both supported
we're in the process of factoring out the backend server for both lab and notebook
and then the (tentative) plan is to move lab to the new jupyter server project by JLab 3.0, June 2020
Carl Simon Adorf
@csadorf
@jasongrout Thank you for the info. Can you point me to where these discussion are held and documented?
Jason Grout
@jasongrout
We haven't had a discussion about deprecating notebook in a while.
Carl Simon Adorf
@csadorf
Thank you for the link.
I am trying to determine how urgent the transition as an application and widget developer to the new platform is.
Jason Grout
@jasongrout
As a personal opinion, the classic notebook probably won't be deprecated in the next 6 months.
if that helps
Carl Simon Adorf
@csadorf
That does help, although I wish there was a bit more transparent communication about this from Project Jupyter.
Jason Grout
@jasongrout
I think a specific timeline hasn't been decided
JupyterLab now has a 6-month major release cadence
so 2.0 this month, 3.0 in mid-2020

@aishenri
I hope not too quickly because I use music21 midiplayer which is not working in jupyterlab ?
Angus Hollands
@agoose77
@aishenri you can still use the old notebook, you just can't use the latest features :)

From the error, it sounds like you could check the permissions on that file and the containing directories

Hi Guys -
Can someone please point me to any documentation to get started with Jupyter web/browser core development. How the notebook UI is architected, what are the major javascript libraries used, how the backend websocket machinery is setup, how the nbextensions are loaded etc.
