Brainstorm about notebooks and reproducibility

Konrad’s kind visit triggered an inspiring discussion on his blog about notebooks and reproducibility. As another source of inspiration on this topic, here is a link to Konrad’s article about ActivePapers and the rationale behind ActivePapers: a platform for publishing and archiving computer-aided research

Brainstorm about 3D Visualization

Time: Thursday late afternoon Participants: Florent Cayré, Marcin Kostkur

USilesia has started building a javascript library for static and dynamic (i.e. communication with python objects as ipywidgets do) data visualization in the Jupyter notebook. The project will deliver a first version in December 2015. It will be based on threejs.

In the meantime Logilab will do technology review done for alternative rendering solution. We mentioned using webgl natively, vispy, and paraview.
