When I write code, I normally copy longer variable names. Or 
functions I use more than once. Or import statements, where the path 
remains the same and only the name at the end changes. Disabled copy 
would make me feel thrown back into the age of typewriters. Let's hope I'm 
not representative of your user base, which will have to type out every 
occurrence of every variable and function name, fully qualified.

This is to prevent users from looking at the HTML source? Make sure to 
disable menu items that provide access to this feature, or that allow to 
save the current page as HTML. The notebook edit page is probably not 
stored in the browser cache, but you might want to double-check that.

The people that gave you these requirements are aware that users can still 
type everything they read into a second computer, or make "screenshots" 
with a mobile phone? Disabling copy doesn't stop anyone from getting 
data out of the system. It only makes that slightly more inconvenient, 
while at the same time compromising convenience for the intended use of the 
system as well. Folks who want to steal your data won't mind the extra 
hurdle very much. But folks who have to work with the system on a daily 
basis will.

cheers,
  Roland

Any idea why the "continuous_update=False" doesn't work (for me)? Does it
work for others? - rf. attached .ipynb.

[jupyter] Re: Updating Anaconda has broken Jupyter

[gwheeler]

I ended up having to reinstall Anaconda. Not sure how it got so messed up 
but it turned into a game of whack-a-mole and even creating new virtualenvs 
didn't help.

I'm wondering if asking the users not to change the dataset might not be
better handled by changing data permission either on a file system on with
Read-Only credential.

One additional feature you might want to do, for example to prevent
screenshot, is to blank the window when it loses focus.
I can't guarantied that any of these features can't be worked around though.

[jupyter] Re: Updating Anaconda has broken Jupyter

[gwheeler]

Just checked on the website and it seems that the latest IPython should be 
6.x.

If I run "conda update ipython" conda says I have 6.2.1, but if I run "pip 
freeze" then I get 3.2.3. So something has gotten really messed up somehow.

I'll figure it out.

[jupyter] Re: Register external IPython kernel with jupyter notebook?

[Edward Banner]

Hi Roland,

Thanks for the suggestion. I wound up creating a hacky kernel manager which 
seems to do the job.

https://github.com/ebanner/extipy

The only caveat is that you have to disable message authentication to get 
it to work because jupyter was complaining that the expected message 
signature didn't match.

Re: [jupyter] Blocking copy/paste functionality to JupyterHub

[Michael Milligan]

Hi Jeremy,

Your original question made it sound like you might be using the notebook
purely as a dashboard interface with some level of point-and-click
interactivity. This should be doable using the advice you have already
received, provided you have good control of your users work environment. If
you do not, then you must consider that any restrictions implemented in
client-side JS can be circumvented by browser extensions. This is before
you even consider the screenshot hole, which lately also includes cell
phone photos of the screen.

Now that you have added the requirement that users be able to input and
execute normal code cells, you may need to rethink your security model even
further. A few lines of Python is quite adequate to upload a dataset to an
outside server, load new JS code into the browser, or make arbitrary
changes to locally writable files. In the general case, preventing data
exfiltration is a hard problem, even with very strict controls on the users.

My advice, based on my organization's work to build a system with similar
requirements, is this: if you want to use a system as flexible as Jupyter,
forget about detailed control of how your users interact with data.
Instead, focus your technical effort on detailed logging of which users
have been given access to which data, educate your users about acceptable
data use, and make it crystal clear that they will be held accountable if
data is mishandled.

Regards,
Michael

Hi Matthias,

Thank you for your response. For some background context, the notebooks
will have access to sensitive data sources that we don't want to have
leaving the notebooks, and we also don't want to have users can inserting
their own content into the environment.

Blocking copy and paste is one of the main features that we wish to
achieve. Essentially, we would like to ensure that a JupyterHub notebook
user is able to use and modify their notebooks at will normally (via
typing, clicking and normal keystrokes), but disallow them from inserting
or removing data to and from said notebooks via copy/paste. Additionally,
we would like to prevent the the mouse right click or equivalent keyboard
event as well.

In the meantime, I will go ahead and take a look at inserting the
Javascript example solution you have provided into the Jupyter Notebook
image and evaluate if it meets our requirements. I will also experiment
with additional Javascript code in that js file intercepting other events
(equivalent to right click) in addition to Clipboard event. If you have any
other ideas or suggestions, please let me know.

Thanks again,
Jeremy

[jupyter] [JupyterHub] Debugging make_preexec_fn within jupyterhub-singleuser

[David Doherty]

I've created a custom spawner that copies some Tutorial notebooks into a 
new user's notebook directory to help them get up and running with our 
tools.

However I am getting an exception when I try to run the function I made in 
make_preexec_fn. However, I'm having trouble debugging it. Does this get 
run by the jupyter-singleuser process? Any pointers into how to see the 
logs of that process and generally debug?

I'm using the latest jupyterhub version

Thanks,
Dave

[jupyter] Re: Pdf export in jupyter notebook not working

[ezhick179]

We convert Jupyter to HTML, then print HTML using virtual PDF printer - 
this works.

[jupyter] Attaching custom css and javascript (mathjax macros) to a set of notebooks

[David Ketcheson]

I'm writing a book using a Jupyter notebook for each chapter.  I also 
generate pdf and html versions using nbconvert and bookbook.

I would like to be able to do two things:
 - Control the fonts used in the notebooks
 - Use a common set of Latex macros in all the notebooks

It seems to me that both of these could be accomplished cleanly if it were 
possible to have the notebook load a specific .css file and a specific .js 
file on startup.

Workarounds that I'm not satisfied with:

- Modify the global custom.js for jupyter/ipython.  This will change the 
appearance of all my notebooks, and won't work for other people who read 
the book.
- Loading .css and .js files via commands in a notebook cell.  I'm 
currently doing this for the CSS, but it's hacky since the notebook looks 
wrong when it loads, and then suddenly changes appearance when you execute 
the cell.  It also exposes code that the reader shouldn't have to deal 
with.  For javascript, I haven't been able to get this approach to work at 
all.  If I could, that would at least be a step forward.
- Define latex macros inside math delimiters in a notebook cell.  This 
would require modifying every notebook whenever a new macro is added.  It 
also breaks when converting to PDF, and (again) exposes to the reader 
things that they shouldn't need to deal with.

It seems to me that it would be reasonable to allow notebook metadata to 
specify a CSS file and a JS file to be loaded on startup.  I'm also willing 
to write an nbextension, but I haven't been able to figure out how to do so 
or whether such a thing could solve my problems.

I'd be very grateful for any help from the Jupyter experts, or others who 
have tried to deal with this issue.
