A window on Numpy's views
If you use Numpy for your everyday number crunching and you’ve never heard about views, you are not as effective as you could be. With this post, I want to help you take your Numpy skills to the next level.
Your mental model of what arrays are in Numpy is probably quite different from the underlying reality.

Heteroclinic Switching simulator and visualizer
I’ll soon be pleased to give a talk about my work on heteroclinic dynamics to other heteroclinic people with heteroclinic interests at the Heteroclinic dynamics in neuroscience workshop this December in Nice. In this heteroclinic setting, I thought it would be worth it to have a simple interactive simulation to play with while I illustrate my findings, as I don’t want the talk to be boring, and nothing boosts understanding like a good visualization!
