[EuroPython 2023 — North Hall on 2023-07-20] https://ep2023.europython.eu/session/cultivating-a-performance-mindset As developers, we learn early on that it’s important to focus on getting our code to work without unnecessarily pre-optimizing, but how do we learn to eventually optimize our code? What do we look for? How do you know when something is slow? How do you **do** something about it? In this talk, we’ll discuss why your application performance matters, how you can learn to identify what matters most to you, and how Sentry has you in mind so you can effectively spend time improving the performance of critical user flows in your application.

[EuroPython 2023 — Terrace 2A on 2023-07-20] https://ep2023.europython.eu/session/python-on-arm-architecture Arm is everywhere technology matters: 250+ billion chips in everything from sensors to smartphones to servers. Due to its simplicity, versatility, and growth in popularity over the past decade Python is the most used language in the world. In this presentation I will show you what the status of Python is on Arm architecture on all major operating systems and how you could help to improve it further.

[EuroPython 2023 — Forum Hall on 2023-07-21] https://ep2023.europython.eu/session/cython-3-python-at-the-speed-of-c Cython started as a language designed to write extension modules, and has long become the most widely used static compiler for Python, bringing C and C++ data types into the language. Use it to talk to existing C/C++ code or to bring your Python code up to C speed.

[EuroPython 2023 — South Hall 2A on 2023-07-20] https://ep2023.europython.eu/session/unlocking-the-power-of-what-if-analysis-for-bi-data-and-ai-with-taipy What-if analysis is the key to exploring datasets and assessing outcomes by gradually varying input parameters. It is a vital tool for users in the realm of data analysis and decision-making. However, implementing what-if analysis can be challenging. Join this captivating talk as we delve into the practical implementation of what-if analysis using Taipy.

[EuroPython 2023 — Terrace 2A on 2023-07-20] https://ep2023.europython.eu/session/instrumenting-cpython-with-ebpf eBPF is a amazing technology that can run sandboxed programs in a privileged context such as the operating system kernel. But are eBPF programs limited to the operating system kernel? eBPF programs have fast access to resources like memory. These programs can access the memory of running Python applications very faster, allowing you to instrument Python processes with low overhead! In my presentation, I will show how Python's internal structure supports instrumentation through the use of eBPF. Following that, we'll experiment with eBPF and other modern techniques to instrumenting the Python applications. I'll explain explain why eBPF is more appropriate and efficient technology for instrumentation. By the end of the session, we will have developed an eBPF-based simple tracing tool for instrumenting Python applications. After this presentation, you will better understand how eBPF can help you in the instrumentation of Python applications.

[EuroPython 2023 — Terrace 2B on 2023-07-19] https://ep2023.europython.eu/session/python-linters-at-scale Black, Flake8, isort, and Mypy are useful Python linters but it’s challenging to use them effectively at scale in the case of multiple codebases, in a large codebase, or with many developers. Linter analysis on large codebases is slow. Linters may slow down developers by asking them to fix trivial issues. Running linters in distributed CI jobs makes it hard to understand the overall developer experience. In this talk, we'll walk you through solving those scaling problems using a reusable linter framework that releases new linter updates automatically, reuses consistent configurations, runs linters on only updated code to speedup runtime, collects logs and metrics to provide observability, and builds auto fixes for common linter issues. Our linter runs are fast and scalable. Every week, they run 10k times on multiple millions of lines of code in over 25 codebases, generating 25k suggestions for more than 200 developers. Its autofixes also save 20 hours of developer time every week.
