The Pythran compiler, 7 years later

7 years ago, a first file was commited in the Pythran git repo in order to create a compiler from Python to C . The project now has hundreds of downloads per day on PyPI and has moved to a cross-platform compiler for scientific programs. This talks walks through the initial ideas, sorting out the good and the bad ones and compares the approach with other major Python compilers for scientific programs, most notably Cython, Pypy and Numba.

Relevant topics include :

Numpy compatibility

Abstraction level

Backward compatibility with Python

Taking advantage of hardware

Translating or optimizing

Community interaction

Multi-platform support

Benchmarking

While working on the Mercurial version control system, we hit our heads against the limits of Python's performance. In this talk we will see how Python and Rust can cohabit to play off of each other's strenghts to improve a big open-source project, and what advances have been made in bridging the two languages.

This is a hands-on short tutorial on how to write your own estimator or transformer which can be used in a scikit-learn pipeline, and works seamlessly with the other meta-estimators of the library. It also includes how they can be conveniently tested with a simple set of tests.

For almost 20 years, we relied on a CGI based protocol called WSGI to use Python to handle HTTP requests and responses software. Because Python is singled threaded we relied on a couple of hacks such as Gunicorn or uWSGI to share a socket through multiple processes. However the cost of all these multiple processes was a bit heavy and error prone. Through Django Channels Andrew Godwin paved the way for a better way of creating web services with Python. This work landed in Django 3.0. Let's ...

How does one manage and document change in Python projects, be that new features or deprecation or removal of a feature? Let's explore some of the tools a Python developer can keep in their toolbox for just this purpose.

We, as developer, aim to provide code that, almost matches our team code style, looks better and behaves right. Static code analysis (SCA) tools are one of the way to achieves that. But, with multi-programming languages projects and all kinds of code related needs, It's difficult to address all thoses usecases without dealing with a vast majority of SCA tools. Coala is a — language agnostic — static code analysis framework that provides a common command-line interface for linting and fixing ...

SortingHat is an open source Python tool that helps to manage the different contributor identities within an open source project. Under the hood SortingHat relies on a relational database, which can be queried via SQL, command line or directly via its Python interface. However, these ways of interacting with SortingHat hinder its integration with external tools, web interfaces and new web technologies (e.g., Django, REST services). To overcome these obstacles, we have evolved SortingHat's ...
