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

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.

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.

**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\.

Let's play monopoly in the open area called "The Landing" at the Crystal City Shops. The Landing is right at the Crystal City metro stop and, if you're driving, there is free parking [on weekdays after 4pm and weekends] in the garage. See below for more details. With many tables for games and nearby eateries in the mall, it is a fantastic location for playing board games. We'll be starting at 3:00 pm, but feel free to wander in whenever you'd like.Please RSVP to play. If you'd like to start earlier, feel free to mention that in the comment section. If everyone is already in the middle of games when you arrive, please don't hesitate to pull up a chair and watch a game in progress. We will play a minimum of 3 and a maximum of 6 people at each table. This is a friendly group of competitive and non competitive players and our different backgrounds and different experiences of Monopoly make for interesting conversation during the games. If you're taking the metro, exit at Crystal City and you can walk to The Landing without having to go outside. When you come up the first set of escalators, turn right to enter the underground shops and then turn right at Rite Aide. Continue straight and The Landing will be the large open seating area on your right, next to San Antonio Bar & Grill and Subway. If you're driving, parking is free in the garage. Enter the garage for 1750 Crystal Drive on 18th Street and take a ticket. (You'll need this to exit, but there's no charge). Take the elevators up to Level S. The Landing is the large open seating area next to San Antonio Bar & Grill and Subway. If that parking garage is full, exit the garage and turn left on 18th and left again on Crystal Drive. A second parking garage is located on Crystal Drive between 18th Street and 15th Street.

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.

Whether you've been playing since Guitar Hero 1 like me or want to try out Rock Band 4 for the first time, you're welcome at the Console Gamers Group Rock Band & Rhythm Gaming Meetup! I have a projector equipped loft for Rock Band (Beatles, 3, and 4), Guitar Hero (Warriors of Rock and Live), Dance Dance Revolution/StepMania, and Just Dance. There is also a second bedroom that can be used for games like Frequency/Amplitude, Taiko no Tatsujin, DJ Hero, Beatmania, Parappa the Rapper, Deemo, Voez, the Persona Dancing games, and more. When you arrive please park in a space that does NOT have a number or says "Decal Parking Only"; if those aren't available there's lots of open street parking within the Penderbrook community (I'm right in the middle so either side is cool; parking on Center Way or the middle of Penderbrook Drive is best) but please don't parck on a yellow curb or you might be towed! You'll want to turn at the sign that says "The Greens" onto Golf RIDGE, and then to Golf TEE where I'm the first house on the left. When you enter walk all the way up and to the right; look for the Super Mario Bros. doormat. I'm about 10 driving minutes from the Vienna/Fairfax metro station. We usually go out for dinner at around 5 PM; I live a short drive away from lots of shopping centers including Fair Oaks Mall, Pender, Fairfax Shopping/Towne Center, Fair Lakes Promenade, Fair Lakes Center, and Fairfax Corner. Here's a list of restaurants in the area by food type: [https://docs.google.com/document/d/1Mn6ytvuaaGaBlpVT-9pBSh8fv6X8_V9wzl4eQKYzRT0/edit?usp=sharing](https://docs.google.com/document/d/1Mn6ytvuaaGaBlpVT-9pBSh8fv6X8_V9wzl4eQKYzRT0/edit?usp=sharing) And by shopping center location!

Gaming equipment are not toys. Please be responsible with other people's controllers, consoles, games, furniture, etc. Accidents happen, but if you continuously break things you won't be allowed to use people's equipment. 2. Try and keep a positive atmosphere. A lot of people attend the group to escape from their daily lives. Don't feel like you need to leave your problems at the door, everyone needs to vent once in a while, but please attempt to not do so the whole meetup. We're here to have fun after all, so try and keep it that way! <3

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it. Driving is the best option. There is plenty of free on-site parking. Otherwise, we are a 22 minute bus from the Vienna Metro Station. Bicycling from Vienna is possible but difficult, though once you are here, there's a bike rack in the garage behind the building, and there's also a Capital Bikeshare dock 15 min walk away. **Sponsored by:** Thank you [Fairfax City Economic Development](https://gofairfaxcity.com/) and [Mason Enterprise Center](https://enterprise.gmu.edu/) for making this event possible! **Thank you so much to our wonderful sponsors!** Organized by [DMV Petri Dish](https://www.dmvpetridish.com/) **[Code of Conduct](https://github.com/NoVACodeCoffee/admin/blob/master/code-of-conduct.md):** We value the participation of each member of the community and want all attendees to have an enjoyable and fulfilling experience.
