Python for mathematical visualization: a four-dimensional case study
By: David Dumas
This is a talk about creating pictures of a mathematical
object---specifically, a 4-dimensional fractal "dust" that has been the
subject of mathematical research in hyperbolic geometry since the 1980s. In
the end this is accomplished using a little algebra, a little geometry, and
a healthy dose of Python. That is, I will present a case study of using
Python in several aspects of a mathematical visualization project, from the
computation itself, to transforming and converting data, and finally for
scripting the process of generating the images. Along the way I'll explain
how Python's convenient idioms and containers (e.g. sets and set
comprehensions) are a good fit for some of the algebraic and geometric
questions that come up, how Scipy and Numpy enable fast numerical
calculations, and how Python's strength as a language for scripting and
automation allows easy orchestration of rendering of still images and
frames of animations. The mathematical visualization project we describe is
a collaboration with François Guéritaud (Université de Lille).

Letsencrypt with Python Webapps
By: Joe Jasinski
In-browser encryption is more important now than ever. When building modern
web-apps, encryption is a necessity. This talk will detail how you can
secure your Python-based projects with Letsencrypt, a free certificate
authority available to anyone. It will cover the Python-based tools
available to configure Letsencrypt and an example project utilizing it.
