Abstract: Occasionally we’ll find that some bit of Python we’ve written doesn’t run as fast as we’d like, yet, many aspiring programmers are oftentimes unfamiliar with principled techniques to identify performance bottlenecks in their code. In this tutorial, I will first describe the Python performance analysis ecosystem with broad strokes and then turn to interactive demonstrations to showcase the most prominent tools of the trade on a real practical problem. Speaker: Eyal Trabelsi

Abstract: The eBay open source Exax Accelerator provides high performance parallel and reproducible workflows in Python. In this talk, we'll focus on a big data application and show how to use it to prototype an animation of the large NYC taxi dataset, highlighting the 2020 Corona lockdown effects. https://github.com/exaxorg/pycon20-nyc-taxi-covid-movie About the speaker: Anders Berkeman

Abstract: Serverless allows us to build and run applications without thinking about servers. Additional benefits are that the cloud provider can take care of tasks we usually do with code, like error handling and retries. Let's look at how serverless can reduce the Python code we write and focus on the pure business logic. About the speaker: Gunnar Grosch

Abstract: Writing a decorator to modify the wrapper function inside another decorator, so that keyword arguments on the modified decorator show seamlessly on the docs and signature of the final, decorated, function. Let's dive into the pure Python code which manipulates the function object attributes themselves to get this working. Real use case. About the speaker: João S. O. Bueno

Abstract: You curse once again at the monster function that needs to change. Add some technical debt with another if-block or spend the day carefully adding tests trying to "understand it"? There is another way: approval testing. I'll demonstrate the technique to give you an idea of how it works! About the speaker: Olof Bjarnason

Abstract: In every development context and scenario, there are repeatable patterns and codes we use more than once. Using a templating engine and making it configurable is an effective way to have this code built out for you. Making the templates configurable, makes them flexible, and enhances re-usability. The key ingredients for this talk are: Jinja (templating library), YAML (to make templates configurable), and a little bit of Python to make all of this work. The objective of this talk is to get you started on building your own Solution Accelerators. When it comes to solution development, speed is of the essence!

Abstract: With ML being the new shiny object, No one really talks about the data pipelines that make the data consumable. Single streamlined data pipeline may sound cozy but no one want’s to sit through 10 hours for ingesting 2 million records, do you? Trust me you don’t. The solution? Distributed data pipelines. About the speaker: Bhavani Ravi

Nothing much to say about them other than the fact that they are great budget linear switches. They are pretty smooth for the price that you are paying. Lubed Gateron Yellow Sound Test : https://www.youtube.com/watch?v=jv1kJkqBzpw&t=3s

Abstract: The Web Traversal Library is a powerful, high-level framework for scraping and interacting with the web, developed at Klarna for reinforcement learning applications, and now completely open source. Let's see how it works and what it can do! About the speaker: Marcus Näslund is a mathematician, educator, writer and software engineer at Klarna in Stockholm.
