[French version below] You’ve built an API — or at least explored one. But have you ever used an API that documents itself, validates your data automatically, and tells you exactly what went wrong… without writing extra code? Welcome to FastAPI. FastAPI is one of the most popular modern Python frameworks — and for good reason. It’s fast to write, hard to break, and comes with powerful features that used to take hours to set up, right out of the box. In this hands-on workshop, we’ll build a real API together using FastAPI and discover what makes it such a game changer compared to traditional approaches. 🔍 **What we’ll explore** * How FastAPI differs from frameworks like Flask * Using type hints as real validation tools (not just documentation) * Pydantic: define your data once and get validation + clear error messages for free * The magic of /docs: an interactive API documentation generated automatically from your code 👩‍💻 **Workshop style** This is a hands-on session — we’ll code together step by step, so you can follow along and experiment in real time. 👉 **Who is this for?** * You have basic Python knowledge * You’ve seen or built a simple API (e.g. with Flask) — or you’re curious to go one step further * You want to understand how modern APIs are built today 🧰 **What to bring** * Your laptop with Python 3.x installed * A code editor (VS Code recommended) * Install before the session: pip install fastapi uvicorn requests * Enthusiasm and curiosity! ✨ By the end of the workshop, you’ll have your own working API — and a solid understanding of why FastAPI is becoming the go-to framework for modern backend development. *** **Construisez une API moderne avec FastAPI** Vous avez déjà créé une API — ou au moins exploré ce concept. Mais avez-vous déjà utilisé une API qui se documente toute seule, valide automatiquement vos données et vous indique précisément ce qui ne va pas… sans écrire de code supplémentaire ? Bienvenue dans FastAPI. FastAPI est l’un des frameworks Python modernes les plus populaires — et ce n’est pas un hasard. Il est rapide à écrire, difficile à casser, et propose des fonctionnalités puissantes qui demandaient autrefois des heures de configuration, directement prêtes à l’emploi. Dans cet atelier pratique, nous construirons ensemble une véritable API avec FastAPI et découvrirons pourquoi il change la manière de développer des APIs par rapport aux approches plus traditionnelles. 🔍 **Ce que nous allons explorer** * Ce qui distingue FastAPI de frameworks comme Flask * L’utilisation des type hints comme outils de validation (et pas seulement de documentation) * Pydantic : définir vos données une seule fois pour obtenir validation et messages d’erreur clairs automatiquement * La magie de /docs: une documentation interactive générée automatiquement à partir de votre code 👩‍💻 **Format de l’atelier** C’est une session pratique — nous coderons ensemble étape par étape, afin que vous puissiez suivre et expérimenter en temps réel. 👉 **À qui s’adresse cet atelier ?** * Vous avez des bases en Python * Vous avez déjà vu ou créé une API simple (par exemple avec Flask) — ou vous êtes curieux·se d’aller plus loin * Vous souhaitez comprendre comment les APIs modernes sont construites aujourd’hui 🧰 **À apporter** * Votre ordinateur portable avec Python 3.x installé * Un éditeur de code (VS Code recommandé) * À installer avant la session : pip install fastapi uvicorn requests * De la curiosité et de l’enthousiasme ! ✨ À la fin de cet atelier, vous repartirez avec votre propre API fonctionnelle — et une bonne compréhension de pourquoi FastAPI est en train de devenir un standard pour le développement backend moderne.

**Welcome to our June UX Beers in Antwerp!** This time, we will host our event on Tuesday the 30th of June at Craftzing in Antwerp.

So with AI emerging, it can feel like a lifeline: faster prototyping, '*deeper*' research, and more concepts to explore. But somewhere between the third AI-generated prototype and losing the thread of your prompted designs, it can become painfully obvious what the impact is of designing with LLMs. We're not executing anymore, we're reviewing, approving, and critiquing, like a manager. This talk gets honest about what that actually means: the speed gains are real, but the cognitive debt is quietly compounding, and your future as a designer depends on understanding why. Explore how designers can protect their cognitive depth, enhance their review capacity, and stay in control when the machine can almost draw anything. **Talk 2:** **Growing UX in organisations that are not there yet.** By Koen Peters, Designer at Namahn More and more organisations are asking us to help build design expertise in-house, even putting together a design team for them. I have learnt that in such cases, you need to set aside your own biases and assumptions first: your neatly mapped-out methodology, your Figma dogmas and all the other things you as a design agency take for granted. The reality in these organisations is often very different: limited resources, no design culture and few or no trained designers on the team. Through a few client case studies, I will show how we have tackled such challenges. Organising a training in UX and design thinking is a good first step, offering a chance to get to know the team and identify which skills are already there and which are missing. I will also demonstrate tools and activities that we have used to help a team get started and become more aware of UX research and design. These include a script for choosing the right UX approach, skills assessment models to identify gaps and first steps towards creating a design playbook. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.
