    astrojuanlu hi folks, I'm reading on native-authenticator but I don't see how to specify the passwords for my users in advance.

    I also saw remotecsv-authenticator, which I can kind of tweak for my needs by storing those passwords somewhere, but I'm wondering if there's something else I should look at

    astrojuanlu to be clear, I already have a list of emails, and I would like to specify a password for each of them in advance.

    astrojuanlu well, it seems that I can edit the dbm database with a script ✨

    Hey guys, I have been trying to create a modified Jupyter Lab workspace which is a split-area with Launcher on the left tab and a webpage on the right tab. The webpage requires JSON configuration details as in the URL & text ("data" : {"url": <>, "text":<>}) but I haven't been able to find the details to feed for the Launcher widget. I have tried to combine the default workspace widget details which pulls up the Launcher on server start but it seems that the default workspace ha some extra set of logic somewhere to do that outside the workspace. Any help on the Launcher widget details for workspace would be greatly appreciated.

    @minhajsixybte not-an-expert but, it seems like you need to install /change the appropriate graphics backend. I briefly read something here that might be of use: https://pypi.org/project/octave-kernel/

    Hey guys
    any clue on this behavior?

    @andrealorenzon
    the same happens with other widgets, like filechooser
    they loose the status when used as class attributes

    Hi, is anyone having issues with mysql.connector in the Anaconda environment. All of a sudden mysq.connector.connect() return an error stating that 'connect' is not an attribute of mysql.connector. I have tried running it in Atom and Pycharm and it works just fine. Any info would be of utmost help

    How does the jupyter Kernel shutdown process work, exactly?

    for example, in JupyterLab, if I follow these instructions to shutdown a kernel, what happens? Is the relevant code here in jupyter_client?

    Appreciate the help

    @kevin-bates
    Yes, that’s the relevant code that finds its way from the notebook server’s kernel handler, through the multi-kernel-manager to there. :smile:
    In general, a message-based shutdown request is sent to the kernel and followed up by a couple degrees of process shutdown (SIGTERM, then SIGKILL) depending on the poll results against the subprocess.

    Hi All! I am new here and new to Jupyter, and I have a bit of a project I am hoping to get some direction on... I work with some people who are not programmers, and I want to use Jupyter to create small applications/tools for them that are interactive, but don't require them to manually run (or ideally even to see) any code. In a perfect world, I would like to create a dashboard with some buttons/dropdowns/text input boxes that they can use which will execute upon changes (input, change in dropdown selection, etc...) and show some outputs. Does anyone know good extensions or guides I could look into? Thank you all so much for your help!

    Hi! are you aware of a jupyterlab extension to facilitate search for notebooks? something like the https://jupyter-contrib-nbextensions.readthedocs.io/en/latest/nbextensions/tree-filter/readme.html but for jupyterlab
    naveace
    @naveace
    @minrk @epifanio thank you both so much! Voila seems to be exactly what I need :)

    hi, anyone can point me at resources about how to upload and analyze files in a interactive webpage generated from a notebook with nbinteract?
    @naveace , if you have to upload files for you interactive analysis, are you willing to share how did you do that?

    As a followup to my last question: I have a project consisting of some tools + widgets which I turn into a usable app via Voila, and I am hoping to share it with my non-technical colleagues; this means their devices have no conda installation, no python executable, etc…, and I need to be able to share it without having then get all of these things themselves. Unfortunately, shared infrastructure/server hosting (e.g. Binder) is not an option due to security considerations, so I am hoping to create some kind of executable file they can just click on which will use a packaged python installation and libraries to run the app. Does anyone have ideas as to how I can go about this? Thank you so much for your help!

    Put everything into a docker container, and make them run it.
    Is running it on a VPS with proper authentication + https not secure enough?
    naveace
    @naveace
    @slemonide It is really preferable to have it in some kind of executable format right now (our security infrastructure is unfortunately not set up to the point where remote sharing is possible yet)
    They unfortunately wouldn't know how to run a Docker container or install Docker
    fyrzbavqr
    @slemonide
    You can create an executable that would install docker and run your docker container.

    I need to disable TLS1.1 and 1.0 on jupyterhub. I tried setting 'c.ConfigurableHTTPProxy.ssl_protocol = "TLSv1.2"' but it seems to have no effect - jupyterhub does not add that argument to configurable-http-proxy. What is the correct way? Do I have to set up a proper webserver as yet another proxy?
    Min RK
    @minrk
    try c.ConfigurableHTTPProxy.command = ["configurable-http-proxy", "--ssl-protocol=TLSv1.2"]

    Hi all. I am new to Jupyterhub and have tasked to find out the following.
    Our team has picked up that multiple sessions are created when new tabs are open. Is there a way to ensure that only one session is used even when the IDE is open in multiple tabs?

    @minrk Thanks!

    @minrk Nope, crashed on startup... https://termbin.com/tnyz

    @minrk
    sorry, that should have been TLSv1_2
    Nathan Fish
    @lordcirth
    @minrk It worked! Thanks! Shouldn't the configurable-http-proxy --help say that as well? It says "TLSv1.2"

    @minrk
    @lordcirth what version of CHP? I have 4.2.2 and it has:
    --ssl-protocol <ssl-protocol>      Set specific SSL protocol, e.g. TLSv1_2, SSLv3

    Hello Guys,
    I have installed python 3.9.0 and installed Jupyter noteboot
    iam getting error
    while running jupyter notebook
    Traceback (most recent call last):
    File "/usr/local/bin/jupyter", line 5, in <module>
    from jupyter_core.command import main
    ModuleNotFoundError: No module named 'jupyter_core'
    can any one tell me what to do
    Angus Hollands
    @agoose77
    @kdeepak99 it looks like you're installing into your system packages (with sudo) which is a recipe for disaster :boom:. You should uninstall the things you installed as best you can, and then use virtualenvironments
    DiPAK KNVDL
    @kdeepak99
    @agoose77 all things will work in virtual environment?
    Angus Hollands
    @agoose77
    I don't know exactly what's causing your error, but it looks like it is likely to do with installing into the system Python directories, which can easily be broken during development. Cleanup your system Python, and then use a venv to keep things clean. I recommend pyenv with pyenv-virtualenv
