For the month of April, we have two awesome talks about **Python Decorators** and **building a load balancer using the new NoGIL biilds**.

Schedule:

* 👋 & 🗣️ 18:45: Welcome and Talks
* 🍕 **&** 🍻 20:00: Networking, food and drinks!
* 👋 21:00: Bye!

* ➡️ **What:** Why Decorators?
* 📢 **Who**: Dirk Lüdtke
* ⏱ **Duration**: 30 minutes
* 👅 **Language**: English
* 🧐 **Abstract**: Python first introduced decorators way back in 2004 with version 2.4, as a powerful tool for enhancing the behavior of functions and (later on) classes all in a neat and concise way. You are probably familiar with some popular decorators like @classmethod, @app.route (Flask), @validator (Pydantic), and @tf.function (TensorFlow). While most of us happily use them, few actually create our own. Decorators are convenient, but they’re not without their quirks. As I write this, I’m still a little on the fence about using them too liberally. But fear not! By the time we get to the talk, I'll share some intriguing insights, show you where decorators truly shine, and highlight a few hilarious examples of flagrant misuse.

* ➡️ **What:** Building a NoGIL Load Balancer in 30 minutes
* 📢 **Who**: Alvaro Duran
* ⏱ **Duration**: 30 minutes
* 👅 **Language**: English
* 🧐 **Abstract**: Load balancers are widespread nowadays because most software systems are web-centric and service oriented. However, they’re extremely complex to build, because they must be very performant and use sophisticated algorithms to route traffic. Until recently, you couldn’t use Python to build one, because even though it would make the code simpler, the GIL prevented multiple threads from executing Python at the same time.

Now that you can, what are the practical implications in your day-to-day work?
In this talk, we’re going to live code a load balancer in Python. This will help us understand the pros and cons of using modules such as asyncio, threading and concurrent.futures, and what changes when we remove the GIL from the way.
Whether you’re building systems that demand concurrency (such as AI models or DevOps pipelines), or you’re just curious about how tools like gUnicorn or Starlette work under the hood, you’ll come away with practical insights on how to start off the NoGIL era on the right foot.

➡️ Access Control

* 🛂 The security access control requires an **attendee list** (full name) and a **means of identification** (DNI, NIE, passport)
* ⚠️ Make sure you register for the event with your **full name** and **ID**. Otherwise, you will be REMOVED from the attendance list.
* 🪪 You’ll be asked to provide that ID to access the building.
* 🚸 People under 18 years old shall be accompanied by a legal guardian

Python Meetup April: The Spring Meetup

Cloudworks

Rejoignez-nous pour une session en ligne enrichissante consacrée aux agents d'intelligence artificielle, ces systèmes autonomes qui peuvent percevoir leur environnement, prendre des décisions et agir pour atteindre des objectifs spécifiques. Que vous travailliez dans le marketing, les ressources humaines, le développement logiciel, la finance, la santé, l'éducation, ou tout autre secteur désormais impacté par l'IA, ou que vous soyez simplement curieux des avancées technologiques, cet événement vous permettra de comprendre les fondements des agents IA, d'explorer leurs applications pratiques, d'apprendre à en créer vous-même ou à utiliser les agents IA pratiques existant déjà sur le marché.

***Format :***

* **Durée** : 2 heures
* **Plateforme** : Zoom
* **Date** : 02/05/2025

***Programme***

* Introduction aux agents IA : concepts fondamentaux
* Frameworks Python de création d'agents IA et des systèmes multi-agents
* Le protocole MCP (Model Context Protocol)
* Utilisation d'agents IA populaires

We are continuing our Study group online for the time being.
We are now meeting online in the San Diego Python Discord server! Here is the link to join: [https://discord.gg/8GpWuVvdbQ](https://discord.gg/8GpWuVvdbQ)
There is a "meetup" voice/video channel that we will be using!

We may start meeting in person soon! This will be discussed at the meetup. We are considering having some online, some in-person. Decisions, decisions!

Every Saturday we meet up with the larger Python community (including San Diego PyLadies (http://www.meetup.com/sd-pyladies), Open BioInformatics San Diego (https://www.meetup.com/Open-Bioinformatics-SanDiego/) and San Diego Artificial Intelligence (https://www.meetup.com/SanDiegoAI/)) to chat, learn, and hang out.

Our study group is for everyone on their Python journey, whether you're just starting out, an experienced pro, or anywhere in between. There's no formal instruction, just a bunch of folks who like to code. Sometimes we talk about a specific subject, sometimes answer questions, whatever!

Python Community Code of Conduct (http://www.pythonsd.org/coc): Python is much more than a software language. Python is a vibrant community made up of members from around the globe with a diverse set of skills, personalities, and experiences. It is through these differences that our community experiences great successes and continued growth. Overall, we're good to each other. We contribute to this community not because we have to, but because we want to.

**Please note the change in date!**

With AI becoming increasingly integrated into professional workflows, it's reasonable to ask whether our traditional approaches to organizing knowledge remain relevant. This talk explores why taxonomies matter, now more than ever, as a way of mediating between human expertise and AI capabilities in complex domains.
We'll examine how taxonomies can enhance AI systems through improved data organization, output validation, nuanced context and domain-specific tuning.
We'll demonstrate how taxonomies can be key to data quality in complex domains, and review some technical principles in taxonomy design, classification schemes, and quality control mechanisms,
We'll showcase the Data Operations IL open source taxonomy project as a practical case study. The project is mapping the professional landscape of data professionals in Israel, to benefit the community with a data foundation for various needs such as career path analysis, skills gap identification, job market trend analysis, and more.
