Concurrent Programming

Podařilo se nám na poslední chvíli sehnat výjimečného hosta – a bylo by škoda to nevyužít! Martin Urza, anarchokapitalista, youtuber a autor první české knihy o anarchokapitalismu, přijede osobně představit svou novou knihu **Anarchoagorismus**. Anarchoagorismus není jen teorie. Je to praktická cesta ke svobodě pomocí prostředků dostupných každému z nás, tady a teď. Urza nám vysvětlí, co za tímto pojmem stojí, proč ho považuje za logický vývoj svého myšlení a jak tyhle myšlenky aplikovat v každodenním životě – bez čekání na revoluci. Počítejte s živou diskusí, protože tohle téma málokdy nechává lidi lhostejnými. A samozřejmě – večer zakončíme kvalitním pokecem u piva a v atmosféře bublajících dýmek. Kapacita je omezená, takže neváhejte – kdo přijde, nezklame se!

**SignUps on [LUMA](https://luma.com/wf99go3k) Only** [https://luma.com/wf99go3k](https://luma.com/wf99go3k) Hi PyLadies Berlin! In this members' talks evening held in-person and online, we will have an introduction from our sponsor Blacklane and some very insightful talks 🥳 **💡Erica Wolf - Queer coding** There are different meanings of Queer Coding. I will focus on the meaning grounded in Critical Theory and how Python, specifically, addresses this idea. **Level:** Experience of Python is not required 👩‍💻 Erica Wolf is a transgender woman, who escaped the political Dystopia of the USA in 2023. She has been writing Python for 20+ years and got to go through a painful transition from 2.7 to 3.X (I still always format my PRINT and RETURN statements wrong). She got an MS in Geographical Information Science (Make maps with computers) in the USA Currently, she is a Mentor/Coach for FLINTA people who have found themselves as leaders in Tech Startups. **💡Lisa Johannsen - Crypto Bot** She will introduce my CryptoBot project, which combines real-time data processing, machine learning, and scalable system design. By comparing historical price data with live streaming data, the model predicts price movements and determines whether to buy or hold. **Level:** Intermediate Developer 👩‍💻 Lisa Johannsen is a Diplom Engineer from Berlin working as a Data Engineer. She enjoys building reliable and scalable data systems, while finding the right balance between automation, trust in data, and human expertise. For her, the best data solutions come from combining solid engineering with critical thinking and real-world context. **💡Maya Öykü Gümüs - Navigating Technical Interviews: Lessons From Both Sides** ​In this talk, I share my journey from being a tech candidate and an interviewer, offering a behind-the-scenes perspective on the hiring process in 2026. Drawing from experiences on both sides of the table, I’ll break down how technical interviews are structured today, what companies are really evaluating, and how expectations have evolved. Attendees will gain practical insights into modern tech hiring trends, common pitfalls, and how to approach interviews with greater clarity and confidence—whether as candidates or future interviewers. ​ ​**Level:** Experience of Python is not required ​ ​👩‍💻 Speaker introduction ​ ​\*\*[✨](https://emojipedia.org/sparkles/) Blacklane\*\* our wonderful host. *** ​📆 Agenda ​18h30 Doors open ​19h10 Community Announcements ​19h20 Welcome from our sponsor ​19h30 **Erica Wolf - Queer coding** ​19h40 **Lisa Johannsen - Crypto Bot** ​20h20 Short break ​20h30 **Öykü Gümüs - From Candidate to Interviewer: Understanding Tech Hiring in 2026** ​21h00 Networking ​21h30 See You Next Time! :D *** ❓ Can men attend ❓ Everyone is welcome. :) If you identify as someone well-represented in open source and in tech, please be mindful of the space and privileges you have, and use it to support others.

Hello Python enthusiasts and models both large and small, The 34th PyData meetup will take place at **Similarweb offices** (Dock in Five, reception A, 5th floor). As usual, the talks will start at 18:30 but we encourage you to come as soon as **18:00** to enjoy the opportunity to socialize and refresh yourselves (which you can continue doing during the break and after the talks). Our main goal is to build the community around Python and data and make it welcoming to people of various skills and experience levels. ⚡ If you are interested in giving a lightning talk (up to 5 minutes to present an idea, tool or results related at least to some degree to Python and/or data), please contact us before the event or at its beginning. **Why Your Models Fail: Learning from Regime Shifts in Real Data** **([Alena Pavlova](https://www.linkedin.com/in/alena-pavlova-494610207/), Similarweb)** When building predictive models, we often assume that the data-generating process is stable over time. In practice, this assumption is frequently violated and ignoring it can severely degrade model performance. In this talk, we use stock market price data to demonstrate how overlooking market regimes leads to misleading results and fragile trading strategies. We start by implementing a simple strategy under the assumption of a single, stationary regime and show how it fails in changing market conditions. We then introduce a regime-aware approach to infer latent market states. By applying the same strategy only within appropriate regimes, we demonstrate how performance, risk characteristics, and interpretability can change dramatically. The talk focuses on practical Python implementation, intuitive explanations of regime modeling, and concrete lessons that extend beyond finance to any non-stationary time-series problem. Attendees will learn how to detect regime shifts, incorporate them into modeling workflows, and avoid common pitfalls when working with evolving data. **Training Small Language Models with Knowledge Distillation** **([Gabriela Kadlecová](https://www.linkedin.com/in/gabriela-kadlecova/), distil labs)** Large language models (LLMs) have proven useful across a wide range of real-world applications, from code generation and document analysis to intelligent automation and data extraction. However, their practical adoption comes with some tradeoffs: inference costs can be prohibitive at scale, and sending sensitive data to external cloud APIs raises privacy concerns. Sometimes, a general-purpose model is more than what's needed - if the task is quite specific, a smaller, specialized model could do the job just as well. Small Language Models (SLMs) are a great alternative - running entirely on local hardware, they keep data private, respond faster, and operate at a fraction of the cost. The key challenge is making them good enough for the task at hand, and this is where knowledge distillation comes in. By having a large "teacher" model automatically generate and refine training examples, we can create a specialized "student" model tailored to a specific task, starting from as few as a handful of seed examples. In this talk, we walk through the full distillation pipeline: from defining a task and preparing seed data, through synthetic data generation, to fine-tuning an SLM ready for local deployment. We also present benchmark results comparing base and fine-tuned models, and a live demo showing how capable a well-distilled small model can be.

We will discuss our reactions and interpretations of Poe’s classic 25-page short story, readable online [here](https://www.ibiblio.org/ebooks/Poe/Usher.pdf). Poe is, among other things, often considered the inventor of the detective story and an original voice in the canon of American lit. This story (like many of his) is a romantic-era “gothic” work interested in madness, decay, and the supernatural. I look forward to hearing what you all think!

**„Březnový sraz, kde se řeší kód, právo i budoucnost s AI!“** Zima končí, ale debaty o webu nekončí nikdy. Březnový sraz v [pivovaru Lajka](https://pivovarlajka.cz/pivovar/) je zpátky a tentokrát to bude pestrý mix — od umělé inteligence přes seriálové právo až po networking s lidmi, kteří žijí frontendem a designem. Vezměte dobrou náladu a přijďte! Budeme se scházet postupně od 18:00 a **od 18:30 máme na programu:** * 📰 Nowwwinky od Tomáše Kouta * 🤖 AI tě naučí všechno. Nebo nic. – Karolína Vyskočilová * ⚖️ Seriál Silicon Valley byl více o právu než o techu. Nevěříš? – Karel Navrátil & Jakub Gregorec * 🎲 Risk{f}uj! **Nowwwinky od Tomáše Kouta** 📰 Co je nového ve světě frontendu? Tomáš pro vás jako vždy vybral to nejzajímavější, co se od posledního srazu událo. **AI tě naučí všechno. Nebo nic. 🤖 – Karolína Vyskočilová** Studie od Anthropicu ukazuje, že lidi, co AI slepě poslouchají, rozumí vlastní práci míň než ti, co ji nepoužívají vůbec. Naopak ti, co se zeptat umí, mohou růst rychleji. Kde je hranice mezi „AI mi pomáhá růst" a „AI za mě přemýšlí"? Podíváme se, jak k tomu přistupuju já a budu ráda, když nasdílíte, jak to máte vy. Karolína Vyskočilová – nezávislá vývojářka a konzultantka (kybernaut.cz). Lingvistka, co víc než 15 let programuje weby a aplikace, a teď sleduje, jak se s AI všechno točí kolem jazyka. **Seriál Silicon Valley byl více o právu než o techu. Nevěříš? ⚖️ – Karel Navrátil & Jakub Gregorec** Seriál Silicon Valley není prorokem jen v tech světě, ale i v právu. Na první dobrou jsme to neviděli. Proto jsme se po letech na něj podívali znovu, tentokrát se zkušenostmi právníka i znalostí startup světa. A bylo tam opravdu všechno. Žádná přednáška vám nedokáže vysvětlit realitu práva jako tento seriál. Tvůrci mezi řádky schovali právní rady k nezaplacení. My vám ty nejlepší ukážeme pohledem právníka. Pozor!

CZ: Již druhá akce z nové série meetupů! EN: The second event from a new series of meetups! 18:30 **Přivítání a úvod/Welcome and introduction** *(Ondřej Smrž/Martin Kahoun)* 18:40 **Tech Art v Blenderu: Game Dev a něco navíc/Tech Art in Blender: Game Dev and Beyond** *(Miroslav Horváth - PLAYERUNKNOWN Productions)* CZ: Praktický přehled tech artu v Blenderu se zaměřením na vývoj her – od tvorby obsahu pro rozsáhlé otevřené světy a procedurální generování až po automatizovanou kontrolu kvality herních assetů (QA) a nástroje pro art pipeline. Probereme také přístupy k vyhodnocování výstupů generovaných pomocí ML a odhalování generativních artefaktů a ukážeme, jak Blender zvládne i „divné“ ne-umělecké projekty – například vizualizaci distribuce prvočísel nebo vizualizaci a analýzu sociálních sítí. EN: A practical overview of tech art in Blender focused on game development—from creating content for large open worlds and procedural generation to automated game asset QA and art pipeline tools. We’ll also cover approaches for evaluating ML-generated outputs and catching generation artifacts, and show how Blender can handle “weird” non-art projects too—like prime distribution visualization or social network visualization and analysis. 19:40 **Fluid Simulation in Computer Graphics/Simulace Tekutin v Počítačové Grafice** *(Tomáš Skřivan - SideFX Software)* CZ: V této přednášce se podíváme na základy simulace tekutin v počítačové grafice a ukážeme, jak vytvořit fyzikálně věrohodné simulace ohně, kouře, vody, písku a sněhu. Prozkoumáme tři hlavní přístupy, metody založené na mřížce, na částicích a hybridní metody, přičemž zdůrazníme silné a slabé stránky každé z nich. Také se krátce podíváme na matematický popis tekutin na kterém tyto metody staví a ukážeme, jak slavné Navier-Stokesovy rovnice jsou v podstatě jen Newtonovým druhým pohybovým zákonem. Celá přednáška bude ilustrována konkrétními simulacemi vytvořenými v programu Houdini od SideFX. EN: In this talk we will explore the fundamentals of fluid simulation in computer graphics, show how to create physically plausible simulations of fire, smoke, water, sand, and snow. We examine the three main approaches, grid-based, particle-based, and hybrid methods, highlighting the strengths and weaknesses of each. We also take a brief look at the underlying mathematics, showing how the famous Navier-Stokes equations are essentially Newton's second law of motion.

(Pozor, změna místa konání → Vlkova 628/36, Praha 3) Rozdíl mezi „zkusil jsem ChatGPT“ a **smysluplným využíváním AI ve vývoji** je obrovský. Na tomhle Qeetupu se podíváme na to, jak s AI pracovat **systematicky**: * jak AI testovat, ladit a dlouhodobě zlepšovat, * jak mít přehled o tom, co model dělá a proč, * jak AI zapojit do reálných workflow, ne jen jako chytrý autocomplete, * a co se změní ve chvíli, kdy nechceš nebo nemůžeš spoléhat jen na cloud a začneš řešit **lokální modely.** Žádné základy. Žádné „co je to LLM“. Tohle je **meetup pro vývojáře**. **Testování, evaluace a monitoring LLM agentů** LLM agenti dokážou řešit komplexní úlohy, ale bez správných nástrojů je těžké jim skutečně důvěřovat. Přednáška představí LangSmith jako platformu pro zajištění kvality, spolehlivosti a transparentnosti LLM agentů. Ukážeme si, jak pomocí testování, evaluací a observability zkrátit vývojový cyklus a bezpečně nasazovat AI aplikace do produkce. **Nebojme se malých modelů!** SLM: mýty, realita a praxe, aneb nebojme se malých (lokálních) modelů, kdy dává smysl provozovat SLM, jaké mají reálné limity a výhody oproti cloudovým LLM a jaké use-casy už dnes fungují v praxi. No BS, s konkrétními zkušenostmi a doporučeními. **Kdo bude mluvit?** 🎤 **[Petr Malík](https://www.linkedin.com/in/petr-malik/)** – Team leader, [Qest technologies](https://www.linkedin.com/company/qest-technologies/posts/?feedView=all) 🎤 **[Daniel Čupak](https://www.linkedin.com/in/daniel-cupak-prague/)** – Head of data, [Qest technologies](https://www.linkedin.com/company/qest-technologies/posts/?feedView=all) **Pro koho meetup je?** * Pro devy, kteří už AI používají a naráží na její limity. * Pro lidi, co chtějí jít za hranici promptů a „one-shot odpovědí“. * Pro týmy, které řeší, jak AI používat dlouhodobě, opakovaně a kontrolovaně. * Pro každého, koho zajímá, **kdy dává smysl lokální LLM a kdy ne.**

Pojďme se pravidelně potkávat a sdílet zkušenosti z Power Platformy, co nás na ní baví, co nás trápí a co nového zajímavého přichází. A pokud už nám to někde reálně běží, pochlubme se, jak to funguje nebo nefunguje. Témata jsou primárně Power Automate, Power Apps, Power Pages, Power BI, Copilot Studio, Dynamics 365 a Dataverse. Budeme rádi i za méně pokročilé příspěvky, protože většinou jsme velmi hluboko v technických detailech. **Lokalita:** Fyzicky v Microsoftu v Praze Vyskočilova 1561/4a, Praha 4, 140 00 Místnost Morava Případně online na [https://ppug.community/stream](https://ppug.community/stream) **Jazyk:** čeština **Agenda:** [https://ppug.community/agenda](https://ppug.community/agenda) **Přihlašte vlastní příspěvek:** [https://ppug.community/sessions](https://ppug.community/sessions) **Link na stream:** [https://ppug.community/stream](https://ppug.community/stream) **Občerstvení:** Bagety **Úroveň:** 100-300 Tak si prosím naplánujte čas ve svých kalendářích a přijďte, pokud bude chuť a čas, tak si po meetupu určitě můžeme sednout na pivo.

Control & Clarity in Atlassian Platform direction, admin sanity, and real-world planning Atlassian is evolving fast — new platform concepts, new ways of organizing work, and increasing complexity for admins and teams. At the same time, many organizations are struggling with very practical questions: How do we stay in control? How do we keep things tidy and manageable? And how do we plan realistically as teams and environments grow? At this Atlassian Community Event in Prague, we’ll bring together Atlassian insights, partner experience, and real customer examples to explore how teams are navigating change — and what actually works in practice. 🎤 Agenda & Speakers Service Collection: Platform Direction & What’s Coming Next Darryl LeeSolutions Engineer, Atlassian Darryl will give a high-level introduction to Service Collection — what it is, why Atlassian is investing in it, and what it means for existing customers. The session will also include a look at the roadmap and upcoming changes, helping attendees better understand where the Atlassian platform is heading and how to prepare for it. Atlassian Cloud and the Loss of Control Ed LetifovTechTime Initiative Group Limited Sometimes it feels like too much is happening in Atlassian — too fast, with too little visibility. User identities, access, and numbers stop making sense, and admins are left feeling overwhelmed. In this talk, Ed will share real approaches implemented by TechTime’s customers to organize user identities in Atlassian Cloud, reduce chaos, make data consistent, and ultimately lower admin stress. A practical session focused on regaining control and clarity. When Estimation Breaks: Collaborative Planning in Jira at Scale Maria MelnikCTO, Teamlead Jira’s estimation model assumes one person owns one issue. In real teams, work is collaborative — and that’s where estimation starts to fall apart. Subtasks, custom fields, and manual roll-ups can help, but they often create noise, overhead, and unreliable data for admins. This session explores how teams handle collaborative estimation in Jira today, where native approaches hit their limits, and what practical patterns partners use to restore clarity. A real-world discussion focused on reducing admin effort and making planning data usable again. Understanding Team Capacity in Jira: Native Features vs. Real-World Usage Ostap ZaishlyiSenior Product Manager, Reliex Jira offers multiple native ways to view workload and capacity — boards, calendars, and Jira Plans — but how well do these tools work as complexity grows? Using a real customer example, this session explores: What Jira’s native features can (and can’t) tell you Where teams typically hit limitations How add-ons like ActivityTimeline are used to complement Jira and gain clearer visibility into workloads, availability, and constraints — enabling better planning decisions in real-life scenarios 🤝 Networking & Catering As always, the event will conclude with networking, food, and drinks — a great opportunity to: Connect with fellow Atlassian users, admins, and partners Ask follow-up questions to the speakers Share experiences and challenges in an informal setting Whether you’re an admin, a team lead, or simply curious about where Atlassian is heading, this event is designed to give you clarity, perspective, and practical takeaways. We’re looking forward to seeing you!

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
