"Who gets paged? Unit\-testing Grafana notification policies\.*" by Martin Fryč, Staff Infrastructure Engineer at SentinelOne** \*Grafana notification policies decide who wakes up at 3am, and a single mistyped label can silently reroute an alert into the wrong team's branch. Grafana 13 and grafana-operator let teams own their slice of the policy tree, but Alertmanager still evaluates one merged tree, so a too-broad matcher in team A's subtree can quietly swallow team B's alerts. This talk shows a small Go tool that treats routing as code: declarative "given these labels, expect these receivers" assertions, run in CI against the assembled policy. We will walk through the routing semantics, real misroutings the tool can catch, and why multi-tree provisioning makes this test layer more necessary, not less. **2\. "*Using OpenTelemetry in development of resin 3D printers*" by** **Pavel Štrobl** \*In this talk we will take a look how it's possible to get metrics from upcoming resin printers from Prusa Research using OpenTelemetry, why it was not possible to use Prometheus Remote Write and the quirks while getting metrics from hardware constrained environment. **19:40 - 21:30**: Discussion and pizza Note that by registering for this event you consent to related event & product communications from Grafana Labs and agree to our[ code of conduc](https://grafana.com/events/events-code-of-conduct/)t \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **​PLEASE NOTE**: at the SentinelOne office, in line with the venue security requirements - all meetup attendees will be required be verified by their\*\* ID card (or passport\*\*), also to\*\* sign a generic ND\*\*A used for all office visitors and to wear a visitor badge with their name during the whole event - to be able to attend the meetup

Join us for another AI Transformers Prague meetup — a community for leaders, innovators, and practitioners who want to turn AI from buzzword into real business impact. This time organized in cooperation with KPMG. **This session puts AI on trial — through the lens of the EU AI Act.** As regulation becomes reality, companies are being forced to move from experimentation to accountability. The question is no longer *“Can we use AI?”* but *“Are we allowed to — and under what conditions?”* The AI Act is set to reshape how organizations design, deploy, and govern AI systems. But what does it actually mean in practice? Who is responsible? What’s high-risk? And how do you stay compliant without slowing innovation to a halt? *** 🧭 **Theme: AI on Trial — Navigating the EU AI Act** We’ll explore questions like: * What does the AI Act require from companies today and in the near future? * How do you determine if your AI system is “high-risk”? * What are the biggest compliance challenges organizations face? * How can companies balance innovation with regulation? * What practical steps should teams take now to prepare? *** 🎙 **Speakers** Experts from consulting, corporate, and public sector bringing different perspectives on how the AI Act is interpreted and applied in practice: [Martin Čapek](https://www.linkedin.com/in/martincapeklawyer/) – KPMG [Ivana Kudláčková](https://www.linkedin.com/in/ivana-kudl%C3%A1%C4%8Dkov%C3%A1-4b17923ab/) – Český telekomunikační úřad Petr Beránek – MSD *** 🎤 **Format** Short expert talks followed by a panel discussion and audience Q&A — focused on practical implications, not legal theory. *** 📋 **Agenda (June 16)** 17:30–18:00 – Arrival, registration & networking 18:00–18:10 – Welcome & intro 18:10–19:00 – Expert talks 19:00–19:45 – Panel discussion & Q&A 19:45–20:30 – Networking, drinks & informal conversations *** 👥 **Who Is This For?** * Founders & startup leaders working with AI * Product managers & engineering leaders * Corporate innovators & transformation teams * Legal, compliance, and risk professionals * Data scientists and AI practitioners * Anyone affected by upcoming AI regulation Whether you're building AI products or evaluating their use, this session will help you understand what the AI Act means for your organization — and what to do next. *** 📍 **Practical Info** Date: June 16 Time: 17:30–20:30 Location: KPMG offices, Prague Language: English Attendance is free, but spots are limited. RSVP to secure your place and join others navigating the future of AI in Europe. By attending this event, you agree that photos and videos may be used for marketing purposes.

Talk 1 **Title: The Platform Is the People: SLAs, DORA and Trust at Billions of Requests a Month** By: Harry Bouras Role / LinkedIn: AI & Cloud Engineering leader, formerly heading the API organisation of a leading, extremely global and multicultural corporation. LinkedIn: https://www.linkedin.com/in/harry-bouras/ Abstract: Most "platform" talks are about tools. This one isn't. Heading the API organisation of a leading, extremely global and multicultural corporation, interconnecting decades of legacy systems while serving billions of requests a month and scaling across both Azure and Google Cloud, taught me a contrarian lesson the hard way: at that volume, platforms don't fail on technology, and cloud bills don't explode because of bad Terraform. They fail, or succeed, on how the organisation is set up to own, deliver and grow the thing. The org chart is the real architecture. I'll walk through the levers that actually moved the needle, each anchored in real moments from that scale. How SLAs, framed as clarity rather than punishment, change engineer behaviour more than any dashboard. Why extending trust and time to a team up front - the most uncomfortable thing a leader can do, is precisely what raises build quality and cuts the rework you can't afford at billions of requests. What genuinely changed when we dragged a waterfall-shaped organisation toward iterative, Scrum-based delivery, and why that was about shortening feedback loops, not adding ceremonies. And how DORA metrics became our objective answer to a question every team argues about: what actually makes a successful Senior Software Engineer and what a DevOps engineer? Then the human core, told honestly, which means told as comedy. What makes a good manager in this world, narrated through the things I was certain about and was completely wrong about. The running joke is also the real point: nearly every instinct that made me a good engineer made me a mediocre manager until I unlearned it. Finally, a look at what we're all about to get wrong together: AI is forcing DevOps to grow up into DevSecOps - and the teams that handle it well will be the ones that already have the ownership, trust and growth culture this talk is really about. Talk 2 **Postmortem Culture: Turning Failures into Learning, Not Blame** By: Dani Yelovitch Most engineering teams treat incidents as embarrassments to bury — a quick fix, a vague Slack message, and everyone moves on. This talk argues for a different approach: treating every failure as a gift. The core idea is blameless postmortems — a practice pioneered at Google and Netflix where the goal isn't to find a scapegoat, but to understand how the system (people, tools, processes) allowed a failure to happen in the first place. If a human made a mistake, the real question is: why did the system make that mistake easy to make? The talk would cover: What a good postmortem looks like (and the common ways they go wrong) How to run a blameless review without it becoming a blame-by-committee session Turning action items into actual change, not a graveyard doc nobody reads Building psychological safety so engineers report problems early instead of hiding them The key takeaway: teams that learn from failure faster than their competitors ship better software with fewer catastrophic incidents — not because they have better engineers, but because they've built better feedback loops. **Talk 3:** Title: From Service Organization to Self-Service: Platform Engineering in Action By Pavel Bureš from Sky Modern engineering organisations accumulate platform silos faster than they can pay them down — each team picking its own way to provision workloads, databases, queues and caches, each with subtly different security, observability and cost profiles. In this talk we share how we are tackling that problem at scale through a Platform Engineering practice built on the principle of a unified, abstracted interface for application-centric configuration — an approach that shifts platform teams from "ticket-driven plumbing" to product thinking: stable contracts, golden paths, and self-service by default. In the second half we zoom in on PEaaS (Persistence Engineering as a Service), our concrete implementation of these principles for stateful workloads. We will walk through the architecture — Crossplane 2.0 composition functions on EKS, application-centric Kubernetes claims (XRs), and a tenant-onboarding model that automates IAM, VPC endpoints, OIDC and S3 provisioning — and how it abstracts heterogeneous backends (Keyspaces, Aurora DSQL, Redis Cloud, and Kafka on EKS) behind one consistent interface. Attendees will leave with: A practical pattern for designing engineering platforms in their own organisations. A reference architecture for persistence-as-a-service on Crossplane. Honest lessons on standardisation, tenant onboarding and platform adoption.

See you there!

AKCE JEN PRO ZVANÉ 🤖 Ahoj, v rámci setkávání Research Tuesday jsme naplánovaly Friday special. Cítíme už nějakou dobu, že naše researchová komunita má potřebu sdílet, co nového nám do práce přinesla umělá inteligence, jak nám mění výzkum pod rukama. Chceme si povídat, chceme si navzájem sdílet, chceme vytvořit mapu, kam si zaneseme, v jakých fázích výzkumu a jakým způsobem používáme AI a co nám funguje dobře a co až tolik ne. Pracovat a sdílet se bude převážně v menších skupinkách a výstup se na konci odprezentuje ostatním. Mapu pak pravděpodobně dáme k dispozici komunitě. Pátek 19. června 9 - 12 do Slevomatu v pražském Karlíně. Setkání se koná pouze offline, a kapacita je omezená na 30 pozvaných. Žádná velká příprava netřeba, jen teď dávej víc pozor, kdy a jak v rámci výzkumného workflow používáš AI a jak ti to funguje, ať se o to můžeš podělit s ostatními. **🕒 Agenda:** * **08:30 AM** – Otevření dveří & ranní networking * **9:00 AM** Workshop * **12:00 PM** – Závěr & možný společný oběd **🧸 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 15.6. do 8:00, jestli službu využijete a pro kolik dětí. Podle toho rozhodneme, jestli ji zajistíme. **Rezervace:** Zarezervuj si místo včas. Pokud se ti plány změní, prosíme, uvolni místo ostatním. **Těšíme se na známé tváře i nové účastníky!** Běla, Ivana, Lucie

Sraz pro všechny zájemce o nemonogamní vztahy. Formou neformálního setkání nad dobrotami, které si sami přineseme, budeme diskutovat cokoliv, co nás zrovna bude zajímat. Setkání je vhodné jak pro zkušené nemonogamní/polyamorní osoby, tak pro ty, kteří se teprve chystají podniknout první zvědavé krůčky mimo tradiční monogamní hranice partnerských vztahů. Nejedná se o speed dating, ani jinou formu setkání organizovaného za účelem seznamování. (Ale samozřejmě seznamování není zakázáno) Sejdeme se tentokrát v Riegrových sadech, místo setkání bude označené oranžovým praporkem.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
