colaboratory

As u/halflings pointed out, the current version of Colaboratory offered was spun off some time ago (3+ years ago?) from this jupyter-associated repo: https://github.com/jupyter/colaboratory In another begging-not-ranting, I was surprised that Colaboratory currently only supports 2.7x. It looks like it began around 2014. IIRC most of Google's projects were 2.x upon public release (Tensorflow, the API client) but have since ported over. Jupyter notebooks and iPython, too. Anything particular about Colaboratory that makes a 3.x-port a time-intensive feature, or just something that was not needed during internal development? (Asking as a casual Jupyter user with no knowledge about what code/features is specifically 2.x bound)

This is not new. Check: https://github.com/jupyter/colaboratory Colab is the "mature" verison of Jupyter Colaboratory, which was previously only used internally at Google.

We are planning this as a next feature for Kyso - email me at "eoin [at] kyso.io" if you need this soon. You can currently use https://github.com/jupyter/colaboratory But its not under heavy development anymore, only internally at Google.

It's nice (I tried it some time ago), but I pity that without LaTeX support (one of key things I would need to Google Docs-style collaborating). On the other hand, I tried to enter CoLaboratory from http://colaboratory.jupyter.org/welcome/ and it does support LaTeX, but has issues with connecting to local kernel (I couldn't make it working). And it seems to be no longer id development: https://github.com/jupyter/colaboratory/commit/a4a7176e46c94...

I'm an engineer on the Google team for coLaboratory. In order to have access to Google Drive (which we need for collaborative editing), the app needs access to your Google account. I looking into using a weaker set of permissions, where you grant access to the app to read/write data only to files that the user opened with the App (see https://github.com/jupyter/colaboratory/pull/82). This is a much weaker set of permissions since that app cannot write to arbitrary files in Google Drive. The port of IPython is itself open source (in the repo https://code.google.com/p/naclports/ using the build rule ipython-ppapi), so any developer is free to make their own version (e.g. as a regular web app). We are also working with the IPython/Jupyter team to upstream the collaborative features to the IPython/Jupyter notebook (in a manner that is not
