Slides from the 7th PyData Salamanca MeetUp
The project Jupyter (https://jupyter.org/) has revolutionized the world of research and data science in the last years. It comprises a lot of different subprojects, including the Jupyter Notebook web app, the kernels, the Docker images including modern data science software, JupyterHub, etc.
A lot of people, researchers, and developers use software from this project each day, but, do we know how to take advantage of its full potential?
In this talk, we will give a practical overview of the different features of Jupyter-related applications and environments, ranging the contents from the regular personal use to explain how to enable cooperative Jupyter environments for thousands of users.

We are lucky there are very diverse solutions to make Python faster that have been in use for a while: from wrapping compiled languages (NumPy), to altering the Python syntax to make it more suitable to compilers (Cython), to using a subset of it which can in turn be accelerated (numba), and many many more. However, each of these options has a tradeoff, and there is no silver bullet.
Some years ago I chose numba for poliastro, my personal project, because of its simplicity, effectiveness, and not having to learn a hybrid dialect of Python. numba compiles numerical Python code on the fly using the LLVM machinery, producing extremely performant code... when it works!
On the other hand, even though it is quite mature as a library and most of the Python syntax and NumPy functions are supported, there are still some limitations that affect its usage. In particular, I strive to offer a high-level API with support for physical units (extensions of NumPy) and reusable functions which can be passed as arguments, which sometimes require using complex objects or introspective Python behavior which is not available.
In this talk we will introduce numba, describe its basic usage, and then discuss the strategies and workarounds we have developed to overcome its limitations, as well as some advanced numba features we can leverage. We will focus mostly on CPUs, and mention very briefly its GPU capabilities.
