Over the weekend I started playing around with Shinny. I built a very simple Shinny App using R Studio. Shinny makes it easy to build a web page that interact with R.
Two years ago I build an streaming spark app that pushed caused an iPython notebook, MatPlotLib graph to update. It was pretty easy. I am sure the notebook infra struct has improved a lot. The changes with the work I did in the past was there was not way for the user to interact with the data. E.G. Image they wanted to graph data between two values. Also It was written like a notebook/research paper not a commercial application.
What are other people doing?
