Quadcopters

**Python is often celebrated as the universal glue that can do anything, but what happens when your project scales, a trace breaks, or a lack of architecture becomes your biggest bottleneck?** Join us on **Tuesday, April 21,** for an evening focused on the realities of operating Python at scale. We're bringing together developers and engineering leads from Applifting, ROUVY, and DX Heroes to share hard-won lessons on everything from clean architecture to distributed systems Let's meet in the **Applifting meetup space**, both in person and online. **We’ll start at 18:00.** 👉 [Register here](https://applifting.io/events/python-crew-talk-it-scales-until-it-doesnt) 👈 **if you want to attend in person. Spaces are limited and our event planner Anetka would be sad if we had to turn you away at the door!** **Who’s speaking?** We will kick off with two lightning talks. First, **[Ondřej Doskočil](https://www.linkedin.com/in/ondrejdoskocil/)**, Python tech lead at Applifting, will challenge the mindset that clean architecture is "too Java" for Python and show how AI tools can help you adopt proper structure as your projects scale. **[Stanislav Gurník](https://www.linkedin.com/in/stanleygurnik/)**, backend chapter lead at ROUVY, will follow up with hard-won lessons from the trenches of distributed systems, exploring what it takes to move event-driven Python services from "it works" to "it scales". Then, they will be joined for the panel discussion by **[Jiří Maňák](https://www.linkedin.com/in/manakjiri/)**, software engineering team lead at DX Heroes, and **Martin Jiřík**, senior DevOps engineer at ROUVY. **We look forward to meeting you!** **Schedule:** **17:30 – Doors open** * Get your ticket ready, say hello to others, and have a drink with us. 🥂 **18:00 – Introduction by Filip Kirschner** * Our co-founder Filip will give you a short welcome and introduce our speakers. **18:15 – Architecture in Python: Breaking the 'too Java' taboo with Ondřej Doskočil** * *Why a lack of structure becomes the real problem as projects scale, and how to successfully adopt clean architecture in Python.* **18:35 – Lessons learned from operating Python services in event-driven architecture with Stanislav Gurník** * *Distilling hard-won lessons on the architectural pivots that move event-driven Python services from "it works" to "it scales."* **18:50 – Short break** * *Time to stretch, refill drinks, and chat a bit.* **19:00 – Panel discussion with Ondřej Doskočil, Stanislav Gurník, Jiří Maňák, and Martin Jiřík** * *An open discussion on scaling Python and adopting clean architecture, exploring the realities of distributed systems, operations, and team collaboration.* **20:00** — **Q&A session** * *Your turn.

Čekání je u konce - jedeme dál! Po povedeném návratu se Research Tuesday vrací podruhé. Navazujeme přesně tam, kde jsme minule skončili: u sdílení zkušeností, otevřených diskusí a upřímného pohledu na naši práci bez příkras. **💡 Atmosféra: Bez kamer, jen diskuse** Jestli jsi tu poprvé, připomínáme naši „tajnou ingredienci“: meetupy nenahráváme ani nestreamujeme. Dává nám to svobodu mluvit otevřeně o tom, co fungovalo – i co ne. **🗺️ Téma měsíce: Když UX opustí obrazovku** Co když zákaznická cesta nezačíná ani nekončí v jednom rozhraní, ale vede přes digitální touchpointy do fyzického prostředí, a pak zase zpátky? Co když uživatel neřeší aplikaci, ale snaží se ve stresu a pod časovým tlakem najít správné dveře v nemocnici? **Michaela Holubec Birtusová** UX výzkumnice, facilitátorka a service designérka, která se pohybuje na pomezí digitálních a fyzických služeb. Dlouhodobě působí v organizaci Czechdesign, kde se věnuje především projektům ve veřejném sektoru, od municipalit po zdravotnictví. Kromě toho pracuje na volné noze pro další klienty, kterým pomáhá s výzkumem, facilitací a nastavováním služeb tak, aby odpovídaly reálným potřebám lidí. V posledních letech se intenzivně zaměřuje na výzkum orientace (wayfindingu) ve zdravotnických zařízeních. V rámci výzkumného projektu podpořeného TAČR se podílí na výzkumu, který kombinuje kvalitativní metody, testování v terénu, eye-tracking i VR, s cílem navrhovat navigační systémy, které skutečně fungují. Michaela nasdílí své zkušenosti z výzkumu orientace (wayfindingu) ve zdravotnických zařízeních. Otevře témata, která se v digitálu často neřeší – práci s fragmentovanou pozorností, kontextem, stresem nebo chybou. Probereme i to, jak důležitá je v tomto kontextu přístupnost a jak ji do výzkumu zahrnout co nejvíce. Michaela ukáže case study jako otevřený vhled do procesu: co fungovalo, kde si tým nebyl jistý a kde narážel. **Nové místo & káva:** Tentokrát se potkáme v útulném prostředí **kavárny Ruelto na Andělu**. Abychom podpořili majitele, kteří nám vyšli vstříc, nebudeme tentokrát zajišťovat externí catering. Na místě si ale můžete koupit jejich skvělou výběrovou kávu a lahodné koláčky. **🕒 Agenda:** * **09:00 AM** – Otevření dveří & ranní networking * **9:30 AM** – Úvodní blok: Když UX opustí obrazovku: Jak zkoumat orientaci ve fyzickém světě * **10:30 AM** – Otevřená diskuze * **11:30 PM** – Závěr & networking * **🧸 Hlídání dětí na vyžádání:** Research Tuesday stavíme na tom, že profesní rozvoj má být přístupný všem. Chceme podpořit i rodiče malých dětí, aby mohli zůstat v kontaktu s oborem a potkávat se bez zbytečných překážek. **Máte zájem o hlídání?** Rádi ho na místě zajistíme, ale potřebujeme vědět, jestli o něj bude zájem. Dejte nám vědět v komentářích nejpozději do pondělí do 8:00, jestli službu využijete a pro kolik dětí. Podle toho rozhodneme, jestli ji zajistíme. **🎟️ Důležité informace:** **Vstupenky:** Vstupné na Research Tuesday je dobrovolné. Kapacita je omezena na **35 míst**, abychom udrželi osobní a otevřenou atmosféru. **Rezervace:** Zarezervuj si místo včas. Pokud se ti plány změní, prosíme, uvolni místo ostatním. **Těšíme se na známé tváře i nové účastníky!** Ivana, Lucie, Martin

**Join us in Prague for a Snowflake User Group evening hosted by Everpure (formely Pure Storage).** This edition will bring together Snowflake product updates and practical lessons from teams using the platform in production. We’ll begin with a look at recent developments across the Snowflake ecosystem, including selected new features and broader trends shaping the data platform space. The evening will also include a customer session from Everpure's Metrics team, focused on large-scale data pipelines in Snowflake, including Snowpipe Streaming and experience from high-volume production environments. We’ll round things off with an informal fireside chat with a guest from Snowflake, followed by networking, community discussion, and the traditional Snowflake quiz. **EVENT DETAILS** * **What’s New in Snowflake** Kick off the evening with an overview of the latest developments in the Snowflake ecosystem. We’ll cover new features, emerging trends in the data platform space, and a few practical insights from real-world projects. * **Customer Story: Data Pipelines at Scale** Our host company Everpure's Metrics team will share how they use Snowflake in their data pipelines. The session will focus on large-scale ingestion using Snowpipe Streaming, handling around 10 TB of data per day, and lessons learned from operating high-volume pipelines in production. * **Fireside Chat with Snowflake** An informal conversation with a guest directly from Snowflake. We’ll discuss recent platform developments, what’s coming next, and interesting topics shaping the future of data platforms. The chat will be hosted and moderated live. * **The Snowflake Quiz** As always, we’ll close with the Snowflake quiz, a few goodies up for grabs, and time to connect with fellow data professionals over drinks. **RSVP** here [See Snowflake in Action: Prague User Group](https://usergroups.snowflake.com/events/details/snowflake-prague-presents-snowflake-in-action-prague-user-group-hosted-by-pure-storage-1/).

**Hosted by Sky Czech Republic.** Doors are open from 5:30 pm, talks will start at 6:00 pm. **1\. Marek Svitok \(Sky\) \- Elegance and Safety in Goroutine Management** Concurrent programming is a core strength of Go, but managing multiple goroutines while handling errors and synchronization can quickly become complex and error-prone. The golang.org/x/sync/errgroup package provides a simple and effective abstraction for running multiple goroutines concurrently, propagating the first error encountered, and ensuring all routines complete before proceeding. In this article, we explore why errgroup is a valuable tool, how to use it effectively, and what design patterns emerge from its usage. We also examine how one might implement similar functionality manually, highlighting the pitfalls and edge cases that make a manual approach cumbersome. By comparing manual implementations with the idiomatic errgroup usage, we aim to demonstrate why adopting this package leads to safer, cleaner, and more maintainable concurrent code in Go. **2\. Vilibald Wanca \- Nail the Basics \- S01E03** Go does not use `try/catch` for normal error handling. Instead, it treats errors as explicit return values, while `panic` is reserved for truly exceptional or unrecoverable situations. A panic stops normal execution, runs deferred calls, and can only be intercepted with `recover` inside a deferred function. This makes `panic/recover` closer to an emergency escape hatch than a general exception system. The result is a model that favors clarity and explicit control over hidden flow.

**Over time I'm hoping to organize a hike to all the Franklin County Metro Parks. This is the first one so if you're interested jump in!** **We'll start with the Canopy Walk, a cool feature of this park. Climb 100 stairs to the top - or take the elevator if stairs aren't your thing. At the top there are a bunch of things to play on - a rope bridge, a fireman pole that we can slide down - and more! About fifteen minutes there and we'll head to the natural trail, Buttonbush, Maple and Beech Trail for 2.2 miles then do a 1.7 mile loop on the paved Greenway Trail. We'll be passing our cars as we transition if you only want to do the first loop, or the second loop. Pace of around 3.5 mph but no one left behind.** **If there is an interest we can grab lunch nearby afterward at Prost Beer and Wine Cafe. Www.prostcafe.com**

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration!

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
