Re: [jupyter] Re: The Kernel appears to have died. It will restart automatically ? Please help !

2017-11-20 Thread Brian Granger 
I haven't looked into the details of your configuration, but in
general, Jupyter and the python kernels have no problem using whatever
RAM the system makes available to it. I have created single NumPY
arrays with 1TB of RAM with no problem. If you are running out of RAM,
it is a system level thing related to the configuration of the system,
physical RAM of the system and your deployment of Jupyter.

Jupyterhub is the only bit that could impose such a limit, and you've

I would guess that the SQL work bench doesn't load all of the selected rows
into memory at once. Databases are designed to work with data larger than
will fit into memory, so database software is usually written to load a
bit, process it, discard that, and load the next bit. But if you try to
make a pandas DataFrame from an SQL query, pandas does try to load all the
rows at once.

[jupyter] New zipping notebook extension!

2017-11-20 Thread peterkangveerman 
Hi all,

I wanted to let you know of a cool new jupyter notebook extension, nbzip, 
that let's you quickly download a zipped version of any directory in your 
notebook tree with the click of a button.

Check it out here:
https://pypi.python.org/pypi/nbzip/0.0.1

This extension was created to allow people to more easily transfer their 
work from notebooks running on the cloud to their local machine. This 
issues gives a bit more 
detail: https://github.com/jupyterhub/zero-to-jupyterhub-k8s/issues/152

Thank you,
Peter

Re: [jupyter] Running X11 apps via binderhub

2017-11-20 Thread MinRK 
Interesting! Not super easily, but it may be doable. If you can:

1. start the x/vnc server in the container
2. run a server that tunnels x/vnc data over http
3. serve an http+html/javascript x/vnc client application

then you ought to be able to do it. I'm not sure how many of those pieces
are available, though.

[jupyter] Moving Terminado into Jupyter maintenance

2017-11-20 Thread Thomas Kluyver 
Terminado (http://terminado.readthedocs.io/en/latest/ ) is part of the
machinery that we use for interactive terminals in the browser. Xterm.js (
https://xtermjs.org/ ) provides the frontend in the browser, which is where
most of the complexity is needed, while Terminado is a relatively simple
part that runs on the server. It integrates with the Tornado web framework,
which the Jupyter Notebook is built on.

Currently, Terminado is purely for Unix-like systems. However, there is a
library called winpty which provides the underlying feature to make similar
functionality possible on Windows. The Spyder developers have done some
impressive work to package this up in a form that is readily accessible
from Python and pip-installable, and Steven has opened a pull request on
Terminado to use this.

It would certainly be nice to provide terminals on Windows as well, but I'm
not confident I understand the Windows side of things well enough to
maintain it. Steven has offered to help with maintenance (thanks!), but I'd
like to propose moving it into the Jupyter organisation to make this
easier, and to facilitate other people contributing to its maintenance.

Terminado has generally been a very low-maintenance project - it's simple
glue between a Unix pty and a tornado websocket. Windows support may add
some load, but I don't see it ever needing many changes. Jupyter is the
only user I'm aware of, though over 100 people have 'starred' it, so it may
have some others.

Thanks,
Thomas

You'll need to uncomment these lines for them to affect anything, i.e.
remove the # from the beginning. It also probably needs to be a string -
put "8G" inside quotation marks.

[jupyter] Using Angular with Jupyterlab Extensions

2017-11-20 Thread Simon Biggs 
I have created an npm package that allows you to use Angular within a Phosphor 
widget. This results in being able to use Angular for building jupyterlab 
extensions. The repo is over at:

https://github.com/SimonBiggs/phosphor-angular-loader

It's on npm as @simonbiggs/phosphor-angular-loader

The repo has a little demo widget demonstrating use as within just phosphor. 
I've been using this package to create an extension I am currently working on:

https://github.com/SimonBiggs/jupyterlab-form

Using Angular and creating a jupyterlab extension has been an absolute joy.
