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

We will discuss our reactions and interpretations of Flannery O'Connor's story about the post-segregationist South, readable online [here](https://jerrywbrown.com/wp-content/uploads/2020/02/Everything-that-rises-must-converge-OConner-Flannery.pdf). This is an unofficial continuation of our discussion of O'Connor's story we read last time, but if you weren't there you're still welcome to attend this one as there will be plenty to discuss regardless. I look forward to speaking about it with you!

**Talk 1 – ArgoTs: TypeScript-Powered GitOps with ArgoCD** By: Jiří Soukal - Senior Cloud Engineer, from PriceFX Kubernetes is the de facto standard for cloud-native infrastructure, but managing it often means drowning in YAML. Tools like Kustomize, Helm, and ArgoCD overlays ease the pain, yet feel like patchwork rather than a fix. TypeScript-native solutions such as Pulumi or Terraform exist, but they rely on external state to diff and apply changes—adding complexity for GitOps teams. This talk introduces a new approach: using TypeScript as the source of truth for Kubernetes infrastructure without external state. By extending ArgoCD to understand TypeScript, we can dynamically generate all resources, from workloads to ArgoCD Applications and even cloud provider resources via ConfigConnector or Crossplane. **Talk 2 –** **Securing AI Deployments: From Prompts to AIBOM** By: Marek Sottl, CEO of Hackihub Are you interested in the security of AI application deployments? This packed session will focus on protecting language models and the obstacles that can arise during their deployment from a security perspective. We will explore deployment strategies in AWS and Azure environments, input validation using NLP, prompt tracing, and above all, we will emphasize the importance of AIBOM and MLBOM. **Talk 3 - GitOps, IaTS, OpenRouter and OpenClaw come to a bar** By Martin Pohl GitOps, IaTS, OpenRouter and OpenClaw come to a bar. The bartender says, “Great… who actually has production access?” GitOps says, “Not me, I only sync what’s in git.” IaTS says, “I just generate the infrastructure.” OpenRouter says, “I only route the requests.” OpenClaw says, “Relax, I already decided for everyone.” The bartender slowly reaches for the incident button: “So… which one of you started the outage?” All four reply: “According to the logs, it was a collaborative effort.” Today’s infrastructure tooling is incredibly powerful platforms like ArgoCD, TypeScript-based GitOps, and modern cloud-native stacks allow us to build and manage systems with unprecedented flexibility. But at the same time, we are introducing entirely new layers of complexity and attack surface. This talk explores the intersection of GitOps, TypeScript-driven infrastructure, and emerging AI tooling such as OpenRouter and autonomous agent-style setups like OpenClaw. As infrastructure evolves from static, declarative definitions into dynamic, runtime-generated systems, we are no longer just managing code we are operating systems that can interpret inputs, generate logic, and in some cases act autonomously. With this shift comes a new set of security challenges: prompt injection, tool misuse, model supply chain risks, and limited observability into AI-driven decision-making. The session connects these emerging risks with concepts like AIBOM and modern AI deployment security practices. Ultimately, this talk asks a critical question: are we building the future of platform engineering or creating systems we no longer fully control? **More about Talk 1:** Combining GitOps with the expressiveness of TypeScript creates infrastructure that is both declarative and dynamic, reducing toil while enabling richer abstractions, safer collaboration, and more maintainable platform engineering practices across the CNCF ekosystem. Benefits to the ecosystem \- Clarity & Maintainability: Reduces YAML complexity and templating hacks by introducing a strongly typed\, programmatic way to define infrastructure\. \- GitOps Alignment: Preserves ArgoCD’s declarative\, state\-free model while unlocking the flexibility of TypeScript\. \- Scalability: Makes it easier to manage multi\-cluster and multi\-environment setups with reusable\, composable infrastructure definitions\. \- Innovation in Platform Engineering: Demonstrates how the Kubernetes ecosystem can evolve beyond YAML\-first thinking\, inspiring new tools and workflows that balance developer experience with operational reliability\. \- Community Value: Provides a concrete path for teams frustrated with YAML sprawl to adopt a more maintainable\, type\-safe\, and future\-proof approach—without abandoning the CNCF ecosystem’s GitOps best practices\.

**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. By attending the event I agree that photographs and video recordings from this event may be used by Sky Czech Republic for employer branding and promotional purposes across company websites, career pages, social media, third-party profiles, and other communication materials.

Před několika měsíci vyústila vyostřená debata o filtrech a Core vs Knots v kontroverzní návrh BIP-110, původně známý jako “BIP-444”, neboli Reduce Data Temporary Soft Fork, který má za cíl dočasně omezit časté způsoby vkládání netransakčních dat na bitcoin. Je tento návrh efektivní? Jaké kroky navrhuje? Co se musí stát pro jeho aktivaci a jaká je situace dnes? Lukáš, náš expert na Rust a bitcoin, vám podrobně přiblíží tento problém z každého hlediska. **🦀 PREZENTACE** Tato přednáška představuje BIP-110 v kontextu debaty Knots VS Core, tedy o spam filterech. BIP-110 se snaží se vypořádat se s domnělým i reálným spamem změnou pravidel Bitcoin konsensu, tím že zakáže použití určitých op-kódů a omezí maximální velikosti dat u jiných opcodes. Na BIP-110 se podíváme 1. Z pohledu technického: Co přesně se snaží změnit a proč, kterým metodám se snaží zamezit, a zda zabraňuje některým legitimním použitím bitcoinu 2. Z pohledu časové osy a komunity: Kdy a kým byl BIP-110 vytvořen, kdy se aktivuje a jaké podmínky pro aktivaci musí splnit, jak fungují User-Activated Soft Forky, co se může stát, pokud k jeho aktivaci dojde, a co se může stát, pokud ne 3. Z pohledu efektivity: Jak zapadá do existujících způsobů vkládání netransakčních dat na blockchain, kterým způsobům nezamezuje, a jak se to projeví na ceně vkládání dat **🦀 NETWORKING** Po přibližně 60minutové prezentaci a Q&A zůstáváme na networking u piva. Zůstáváme do 22:00. * Registrace je zdarma. * Bude pití i něco k jídlu. * Odměny za nejlepší otázky. * Knihy od Braiins zdarma. **🦀 PŘEDNÁŠEJÍCÍ** Lukáš Hozda je expert na Rust, autor knihy Building Bitcoin in Rust a lektor kurzů Rust a Advanced Rust na Univerzitě Karlově.

Can it work?** A few months ago, a heated debate about filters and Core vs Knots culminated in the controversial proposal BIP-110, originally known as 'BIP-444', or Reduce Data Temporary Soft Fork, which aims to temporarily restrict common methods of inserting non-transactional data onto Bitcoin. Is this proposal effective? What steps does it propose? What needs to happen for it to be activated, and what is the situation today? **🦀 THE PRESENTATION** This lecture presents BIP-110 in the context of the Knots vs Core debate, specifically about spam filters. BIP-110 attempts to deal with both alleged and real spam by changing Bitcoin consensus rules, by banning the use of certain op-codes and restricting the maximum data sizes of other opcodes. We will look at BIP-110 from: 1. A technical perspective: What exactly it tries to change and why, which methods it tries to prevent, and whether it blocks some legitimate uses of Bitcoin 2. A timeline and community perspective: When and by whom BIP-110 was created, when it activates and what conditions it must meet for activation, how User-Activated Soft Forks work, what may happen if it is activated, and what may happen if it is not 3. An effectiveness perspective: How it fits into existing methods of inserting non-transactional data onto the blockchain, which methods it does not prevent, and how this will be reflected in the cost of inserting data **🦀 THE NETWORKING** After about a 60min presentation and Q&A we will stay to network over a beer, we stay until 22:00. * Register here for free entry. * Drinks and snacks provided. * Giveaways for the best Q&A questions. * Braiins Bitcoin books for free. **🦀 THE SPEAKER** Lukáš Hozda is a Rust expert, author of the book Building Bitcoin in Rust, and a lecturer of Rust and Advanced Rust at Charles University.

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

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.
