[EuroPython 2023 — Terrace 2A on 2023-07-21] https://ep2023.europython.eu/session/how-localstack-is-recreating-aws-with-python At LocalStack, we are building a platform that enables development and testing of cloud applications on your local machine. The core is an [open source AWS emulator](https://github.com/localstack/localstack) that is primarily written in Python. It is among the top Python projects on GitHub, and has seen a massive uptake in contributions over the past two years. Many Python software developers and architects will relate to the struggles of maintaining a large and complex Python codebase, while keeping developer teams productive. In this talk, we'll explore how we at LocalStack tackle these as we re-create AWS for local development. We'll explain our approaches to automating around AWS specifications, building a highly modular and pluggable system to make it easy for teams to integrate their components, the software patterns we use to keep devs productive, as well as our approach to automated contract testing using pytest.

[EuroPython 2023 — Forum Hall on 2023-07-19] https://ep2023.europython.eu/session/how-we-are-making-cpython-faster-past-present-and-future Python 3.11 is considerably faster than 3.10. How did we do that? And how are we going to make 3.12 and following releases even faster? In this talk, I will present a high level overview of the approach we are taking to speeding up CPython. Starting with a simple overview of some basic principles, I will show how we can apply those to streamline and speedup CPython. I will try to avoid computer science and software engineering terminology, in favor of diagrams, a few simple examples, and some high-school math. Finally, I make some estimates about how much faster the next few releases of CPython will be, and how much faster Python could go.

[EuroPython 2023 — South Hall 2B on 2023-07-21] https://ep2023.europython.eu/session/orchestrating-python-workflows-in-apache-airflow [**Apache Airflow**](https://github.com/apache/airflow) is an Open Source workflow orchestrator. It is a python library that allows you to automate complex code and integrate it with a plethora of Data Sources. It is provided with an integrated UI and API for both your human and programmatic needs. After 5 years of running Airflow in production, I hope to share some insights on the technology. The strengths and weaknesses, recommended features and more dangerous ones, and similar considerations on the UI. I'll also be talking about how **you** can make your own *Operators* in Airflow. Come take a deeper dive into the same solution used by Airbnb, Slack, Walmart and many more to efficiently run their data pipelines.

[EuroPython 2023 — South Hall 2A on 2023-07-21] https://ep2023.europython.eu/session/what-a-screen-reader-can-teach-you-about-remote-python-debugging The NVDA screen reader is a Python application packaged with Py2exe, along with C++ extensions for low-level system access and improved performance. Its functionality can be expanded through addons that are also written in Python, which makes the ability to debug both the core and addon code highly desirable. However, debugging code within an embedded or packaged Python environment can be quite challenging, especially if you are a visually impaired programmer trying to debug your own screen reader, since hitting a breakpoint will freeze the tool you rely on for computer access! In this presentation, I will demonstrate how I addressed this challenge by leveraging Microsoft's debugpy library for remote debugging. I will showcase how this technique can be used to debug Python applications running within an embedded Python environment, regardless of the host language. Additionally, I will explore its applicability in debugging applications running on different operating systems or environments than the one where you prefer to use your debugging IDE.

[EuroPython 2023 — South Hall 2A on 2023-07-20] https://ep2023.europython.eu/session/pip-install-malware pip install malware: it’s that easy. Almost all projects depend on external packages, but did you know how easy it can be to install something nasty instead of the dependency you want? I'll be showing this live, as I make malware and install it from PyPI onto my own computer during the talk!
