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.

It also includes how they can be conveniently tested with a simple set of tests.

DESCRIPTION: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 explore how it works and why it worth it!

Let's explore some of the tools a Python developer can keep in their toolbox for just this purpose.

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 all your code.
It is written in Python and supports way over 50 languages in addition to language independent routines. So, instead of building new analysis tools from scratch you can now build your own custom logic and let let coala deal with the rest.
This talk introduces the audience to the Coala Framework and guides them through how the can use it to build routines to do almost anything you want with your code.

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 architecture using a GraphQL model based on the Graphene-Django implementation.
This talk describes our experience in migrating to GraphQL, from adapting the SortingHat functionalities to refactoring the unit tests. Furthermore, we comment also on lesson learned, advantages and drawbacks of using this new approach
SortingHat is one of the core tools of GrimoireLab, an open-source software analytics platform part of CHAOSS project (Community Health Analytics Open Source Software) under the umbrella of the Linux Foundation.

If you have already used it, you know how great it is ! But you also discovered how it can be complicated to follow the state of a complex workflow. Celery Director is a tool we created at OVH to fix this problem : using some concepts of Event Sourcing, Celery Director helps us to follow the whole lifecycle of our workflows. It allows us to check when a problem occurred and relaunch the whole DAG (or just a subpart if tasks are not completely idempotent). During this talk we will introduce you the different concepts of Celery Director then we'll make a demonstration of it.

In this talk however, we approach asyncio from a different angle, one that will possibly help some of you to finally get what asyncio is about. it's not only about performance, but at least as much about correctness and readability of concurrent applications.

ReactiveX is a cross-platform implementation of Reactive Programming. It is heavily inspired from functional programming and contains many operators that allow to create, modify, and combine streams of events. Moreover it is composable and extensible. This short introduction presents Reactive Programming through RxPY, the Python implementation of ReactiveX.

It can be used in high-performance async web frameworks, using either asyncio or trio, and is able to support making large numbers of requests concurrently.
This talk will introduce HTTPX, demonstrate some of its features, and talk through the motivation and aims for the project.

DESCRIPTION:In this talk I would give some motivating examples behind the idea of monads in Python, and show some implementation examples. I'd also show how we can leverage AST transformations to make the Python syntax more amenable to the use of monads. I have already given a talk on this topic during Pycon France 2018 in Lille. Unfortunately, the video footage has been lost, but the original slides can be found here: https://slides.com/v-perez/pythonic-monads-in-real-life#/
If this talk was selected, I'd probably update it a bit to account for the feedback I received, and new ideas I may have.

This information is subsequently used in a recommendation engine that searches large state space of libraries and recommends the best possible combination of libraries suitable for your application using reinforcement learning. Let’s have a look at how such information is collected and how the large state space is explored to resolve the best application stack for your Python application based on different aspects.

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.
