Frameworks, Patterns und Deployment-Modelle – oft steht die Architektur eines Systems schon fest, bevor überhaupt klar ist, was es leisten muss. Aber was, wenn wir den Spieß einfach umdrehen? In diesem Meetup decken wir auf, wie Architektur organisch aus den echten Qualitätszielen eines Systems entstehen kann. Stefan Priebsch zeigt, wie "Domain-Driven Architecture" funktioniert und warum wir uns nicht länger in voreiligen technologischen Sackgassen verrennen sollten. Aber damit nicht genug: Auch in der KI-Welt stoßen wir an harte Grenzen. LLMs sind zwar die aktuellen Stars am Tech-Himmel, aber ihre klassischen Transformer-Modelle fressen Speicher und sprengen bei langen Sequenzen schnell das Budget. Anastasia Hort nimmt uns mit in die Zukunft und erklärt, warum „Liquid Foundation Models“ (LFMs) der nächste logische Schritt sind. Was wäre, wenn neuronale Netze so flexibel wie biologische Systeme und so effizient wie klassische Differentialgleichungen arbeiten könnten? Sei dabei, wenn wir hinter die Kulissen blicken und die Evolution von zukunftssicheren Softwarearchitekturen und der nächsten KI-Generation beleuchten. **\*\*\* Agenda \*\*\*** 17:30 Uhr \| Doors open\. Schnapp' dir Snacks & Getränke\. 17:45 Uhr \| Welcome & Intro 18:00 Uhr \| Liquid Foundation Models: Jenseits klassischer LLMs \- Anastasia Hort 18:45 Uhr \| Domain\-Driven Architecture \- Stefan Priebsch 19:30 Uhr \| GetTogether Wir sind Partner der ROSIK. **\*\*\* Unsere Vorträge \*\*\*** **Liquid Foundation Models: Jenseits klassischer LLMs - Anastasia Hort** LLMs haben in wenigen Jahren unsere Art zu arbeiten, zu programmieren und zu kommunizieren grundlegend verändert. Während manche sie skeptisch betrachten und andere sie nahezu vergöttern, suchen viele nach Wegen, ihr Potenzial effizient auszuschöpfen. Doch klassische Transformer-Modelle stoßen zunehmend an ihre Grenzen: Die quadratische Komplexität der Attention und der speicherintensive KV-Cache machen die Verarbeitung langer Sequenzen extrem kostspielig. Was wäre, wenn neuronale Netze so flexibel wie biologische Systeme und zugleich so effizient wie klassische Differentialgleichungen sein könnten? In diesem Vortrag werfen wir einen Blick auf eine neue Modellgeneration: Liquid Foundation Models (LFMs). Wir analysieren den Paradigmenwechsel von statischen Gewichten hin zu dynamischen, zeitkontinuierlichen Systemen. **Domain-Driven Architecture - Stefan Priebsch** Häufig entsteht Architektur sehr früh durch technologische Entscheidungen, etwa durch die Wahl von Frameworks, Architekturstilen oder Deployment-Modellen. Doch was wäre, wenn wir diesen Prozess umkehren würden? Wenn Architektur lediglich aus den Qualitätseigenschaften eines Systems hervorgeht und sich evolutionär weiterentwickelt? In diesem Vortrag wird Domain-Driven Architecture vorgestellt, ein neues, leichtgewichtiges Vorgehensmodell. Es ist von Domain-Driven Design inspiriert und dessen Prinzipien werden gezielt auf architektonische Entscheidungsprozesse übertragen. Dabei steht nicht nur die Modellierung im Vordergrund, sondern die bewusste Gestaltung einer langlebigen Architektur mit kurzlebigen Implementierungen, die sich anhand konkreter Schwellenwerte weiterentwickeln. Anhand realer Projektbeispiele lernen wir, wie das in der Praxis funktioniert. So entsteht eine Architektur, die gezielte und kontrollierte Veränderungen ermöglicht, ohne durch technologische Festlegungen frühzeitig eingeschränkt zu werden. Der Vortrag richtet sich an alle, die Architektur als evolutive Disziplin verstehen wollen, also als etwas, das bewusst entworfen, kontinuierlich bewertet und weiterentwickelt wird, während sich Domäne und Anforderungen stetig verändern. **\*\*\* Unsere Speaker \*\*\*** **Anastasia Hort** ist Software Engineer bei QAware. In ihrer Masterarbeit beschäftigte sie sich mit Data Science und vertiefte dabei ihr Interesse an datengetriebenen Methoden und Machine Learning. Besonders fasziniert sie, wie Modellierung und Algorithmen helfen können, Ordnung in komplexe, unsichere Systeme zu bringen. In ihrer Freizeit näht sie gerne und liebt es, aus einem simplen Stoffstück mit Kreativität und eigenen Ideen etwas Einzigartiges zu erschaffen. **Stefan Priebsch** ist Berater für Software-Erfolg. Mit über 30 Jahren Erfahrung als Berater, Coach, Trainer, Universitätsdozent und Keynote-Speaker hilft er Unternehmen dabei, komplexe Software in vorhersehbaren Geschäftswert umzuwandeln. Er hat einen Abschluss in Informatik, ist Erfinder von zwei Patenten und Autor mehrerer Fachbücher. Er hält regelmäßig Vorträge auf internationalen Konferenzen, wo er konventionelles Denken hinterfragt und Unternehmen dabei hilft, nachhaltige, weiterentwickelbare Systeme aufzubauen. Stefan ist bekannt dafür, architektonische Klarheit mit geschäftlicher Wirkung zu verbinden. Dabei konzentriert er sich auf Softwarearchitektur, domänengetriebenes Design und entscheidungsorientierte Transformation, um Technologie mit strategischen Zielen in Einklang zu bringen.

We are a group of runners who meet most weeks for a run around the beautiful Vltava River's edge. You can bring your running shoes straight from the office/home office if you don't have time to stop at home. There will be a place to put your bags in the Cafe. We will run about 9 km along the river and have a drink afterwards. Paces vary! We will meet in the square near Kavarna Liberal (Hermanova 6), near the Vltavska metro/tram stop at 6:30 on Wednesday. See you there!

(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.**

**„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! Některé postavy po přednášce už nikdy neuvidíte jako dřív. **„Risk{f}uj!"** 🎲 Čeká nás další kolo oblíbené vědomostní soutěže na frontendová témata. Sestavte si tým, vyberte si kategorii a bodovou hodnotu a zkuste odpovědět správně dřív než ostatní. Těšíme se na vás v pivovaru! 🍻✨

**How does a TennisColumbus Season / League run?** The league advertises the season dates and builds a queue of committed players for the season. **Kickoff Day - March 26th** The start day of the season, players are sent a kickoff email that contains important information about the league, the link where your league standings and players contact information. We guarantee 6 playing partners at your playing level, but have been averaging closer to 15+ partners in most cities. The number of different levels we run is solely based upon the number of players enrolled for the league kickoff. Typically we are running a Skilled-3.0, Competitive-3.5 and Advanced-4.0 in most cities. **Your Task - "Flexible Scheduling"** After this kickoff email is sent, it is the **player's task to communicate with other players**. Players should work with their partners to find an agreeable time and location to play the match. While TennisColumbus doesn't mandate your playing schedule, it is recommended that players schedule at least one match per week. By request of the players, we started to allow players to play 1 rematch per season. The regular season is all about playing as much as you can. As of Feb. 10, 2026 we've had an amazing 2,017 players play more than [20 matches in a season](https://www.tenniscolumbus.com/info/MatchesInSeason). **Where to Play?** Play at your local free tennis courts, tennis parks, condo courts or tennis clubs. The league strongly suggests that players jointly try to pick a tennis court location convenient to both. We provide an extensive list of [tennis courts](https://www.tenniscolumbus.com/TennisCourts), including # of courts, lighting, hitting walls, etc. We strive to keep this list up-to-date. TennisColumbus sets up a must play dates to push players out on the courts. The final deadline is the date marking the end of the season, at which point players with 3-5 wins (Actually total is specified on the division page) will qualify for a post-season playoff to determine the league champion. **How to Play?** Players can use three mostly standard playing formats: 2 out of 3 sets, 2 sets with 10 point super tie-breaker or the 10-game pro set (First to 10, used when court time is limited). On Feb. 2018, we added Fast Tennis 4 game pro set format as a valid format. **Playoffs** Each season concludes with a playoffs where players with anywhere from 3 to 5 season wins qualifies for a single elimination tourney. The champion is awarded based upon the league [Prize Pool](https://www.tenniscolumbus.com/info/prize_pool3). Each singles league champion also receives a playing entry into one of two national championships we run. **[JOIN TODAY](https://www.tenniscolumbus.com/join)** Full price is $39.95 to play in a season. The earlier you sign up we typically offer discounts during these tough economic times. Just go to the [Join Page](https://www.tenniscolumbus.com/join) and complete the short form. We'd be happy to find you dedicated tennis playing partners.

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.
