Visualizing static and dynamic networks in Vispy

Abstract

Vispy is a high performance 2D/3D visualization library which uses the GPU intensively through OpenGL. This Google Summer of code project proposes to add an API to Vispy to visualize static and dynamic (boolean, linear and Bayesian)

If you were to give recommendations to your "little brother/sister" on things that they need to do to become a data scientist, what would those things be?

I think the "Data Science Venn Diagram" (http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram) is a great place to start. You need three things to be a good data scientist:

• Statistical knowledge
• Programming/hacking skills
• Domain expertise

Statistical knowledge

Notebooks are great for interactive use, not so much for being reused in an automatic fashion. How to make a notebook reusable (for example in an analysis pipeline)?

Write your notebook 'mynotebook.ipynb' as usual. Then add a special comment in some cells:

### input
x = 0
y = 0

To change a field name in django 1.7+

1.  Edit the field name in the model (but remember the old field name: you need it for step 3!)
2.  Create an empty migration
$ python manage.py makemigrations --empty myApp
3.  Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

to the operations list.
