Fragments – Multi-Tasking In Jupyter Notebooks and Postgres in Binderhub

A couple of things that I thought might be handy:

• multi-tasking in Jupyter notebook cells: nbmultitask; running actions in notebook cells is usually blocking on that cell; this extension – and the associated examples.ipynb notebook – show various ways of running non-blocking threads in notebook cells.
• a Binderhub compliant Dockerfile for running Postgres alongside a Jupyter notebook; I posted a fragment here that demos a connection if you run the repo via Binderhub. It requires the user starting and stopping the postgres server, and it also escalates the jovyan user privileges via sudo, which could be handy for TM351 purposes.  Now pretty much all I need to see a demo of is running OpenRefine too. I think the RStudio Jupyter proxy route is being generalised to make that possible… and, via @choldgraf, it seems as if there is an issue relating to this: https://github.com/jupyterhub/binder/issues/40 .
