**Please note that this event is not for free and we have limited spots! Save yours by signing up [here](https://locusworkspace.com/events/2026/06/17/happiness-hacks-vs-evidence/)!** **🧠What You'll Learn** “How can I be happier?” is a question we all ask ourselves at different points in life. Many “hacks” have been proposed to answer it: – Think positively – Practice gratitude – Meditate – Exercise more – Socialise more – Help others – Reduce screen time – Stop comparing yourself to others – Act happy But how strong is the evidence behind these recommendations? And do they work equally well for everyone? In this workshop, we will critically explore the psychological science of well-being and learn how to design simple personal experiments to discover what genuinely helps you. **🎤About the Speaker** **Ángel V. Jiménez** is passionate about intentional living, scientific psychology, and the evolutionary study of human behaviour. He holds a PhD in Evolutionary Social Psychology from the University of Exeter, where he studied status acquisition and interpersonal influence, with a particular focus on prestige and social learning.

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.

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.

## **What IdeaVerse is about** **We meet usually once a month to discuss some of the current challenges as well and perhaps come up with new ideas on how to overcome them. The format of the meeting includes an initial sharing of viewpoints by each participant without judgment, and in the second half we will discuss our ideas and try to find things to learn from each other.** **In this next meeting we'll be discussing...** the future of work in the age of AI. I know, people are talking too much about this already in tech meetups where they just praise it to Kingdom Come. We're tired of it. But whether we like that it exists or not, we are confronted with a choice that I'd like us to discuss: **Do I lean into AI like I'm told I HAVE TO, or choose a different path, one more into physical labor or working with people? Or do I just say goodbye to work and start my own business?** We hear thhat AI is going to replace a large number of jobs, starting with call centers, Uber drivers, writers, graphic designers, translators, etc. That a senior expert will replace 4 others in his team using AI. That the only jobs that will remain are those which require human touch like holding meetings, talking face to face with customers, jobs that require empathy or jobs that require dexterity like plumbing. **But the path forward seems so unclear:** 1\. Who should learn AI: young people who want to compete with seniors\, or seniors because juniors don't know enough to spot errors? 2\. Should I double down on AI courses and certificates or jump a sinking ship and learn a craft or improve my social work skills? Or start my own business to escape irrelevance at work? 3\. Do we go with the flow and adapt to this rapid overwhelming change\, or demand from policy makers that they do not let companies do as they please if that means lower wages and unemployment at scale? **Some suggested reading/watching:** * [If AI Takes All Of Our Jobs... Who's Going To Buy Everything?](https://www.youtube.com/watch?v=MYB0SVTGRj4) (the answer may shock you! :) - a 12 minute video) - good summary of the most likely future scenarios for automation and economics. Does not answer our questions but sets the scene for it. * [AI Experts: These Are The Only 5 Jobs That Will Remain in 2030!](https://www.youtube.com/watch?v=GCjmK66x_Yk) (15 minute video) - a collage of various human and AI experts discussing options for work in the future (mostly from the famous DOAC). * [The Future of Jobs Report 2025](https://www.weforum.org/publications/the-future-of-jobs-report-2025/in-full/3-skills-outlook/) (40 minute read) - lots of data, may need skimming but highly useful insight into projections for which jobs will be useful in the future. **The meeting is free to attend, but please buy a drink or two at our patron's place, to make them happy. They also have food in case you find the meeting too early (see [menu](https://altangrebovka.choiceqr.com/section:kavarna---jidelni-listek)).**

NOTE THE TIME CHANGE TO 9AM Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun.

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

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
