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!

**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.

Learning Czech can be hard and demotivating, especially when studying alone. **This meetup is a shared study session where we come together to stay focused, motivated, and make progress — each in our own way.** This is a co-learning / co-studying session, not a class. There is no teacher, no lesson, and no study material provided. Everyone comes with their own resources and studies independently, in a shared environment. 🧠 **How it works** • We all bring our own material: • textbooks • homework from a Czech course • Duolingo or other apps • reading practice • vocabulary review, etc. • We mainly work individually • We are free to: • ask questions • help each other • share tips and resources • No teacher, no formal structure, no pressure 👥 **Who is it for?** • Czech learners of all levels • Non-Czech speakers (expats, internationals) • Czech native speakers are welcome if they want to help, but this is not a language exchange ⏱ **Practical info** • Location: Cafedu 12, Škrétova 490, 120 00 Praha 2 (Metro A and C, Muzeum station) • Duration: 2 hours, or less or more, as you want • Group size: small group for now • Free event — please support the café by ordering a drink ☕ If you’re learning Czech and lack motivation when studying alone, come join us — let’s find it together 🙂

## **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. For those who came regularly, this next meetup would be slightly different. We will do a workshop on solving real world problems.** The problem we will attempt to solve is the dissolution of communities and spaces where people connect in person, and with it, our increased isolation and loneliness. There are many reasons why this is happening: \- replacement of religion with science as a beacon of meaning\, which seems to be much less great at inspiring connection; \- economic forces boosting our ego\, and make it easier to pay for random strangers for help then making lasting connections with people\. \- political polarization \- \(anti\)social media \(as I call it\) and now AI offering simulations of relationships\. \- climate change increasing our distrust in a better future and the importance of investing in life and people\. \- closing down of third spaces like churches\, malls and retail stores \(due to online shopping\)\, youth centers and increase in remote work\. These are all causes we'll explore, together with examples of how other people expressed they feel about this issue from research, reasons why this issue exists as well as examples of small victories against this tide. We'll work in small groups putting all this knowledge together with out imagination and attempt to find local solutions to similar problems here in Prague. This is is more than a discussion. It's an exploration of our ability to work together to effect change in ourselves and in our social circles. **Some suggested reading/watching:** 1. "Contrary to the perception that isolation and loneliness primarily affect older people in high-income countries, they impact the health and well-being of all age groups across the world. One in four older people experience social isolation and the rates are broadly similar in all regions. Among adolescents, between 5­­–15% experience loneliness, according to research findings." (3 minute read - [WHO launches commission to foster social connection](https://www.who.int/news/item/15-11-2023-who-launches-commission-to-foster-social-connection)) 2. "Many popular sitcoms center around what's known as a third place-- for example, Central Park in Friends or the Bull and Finch Pub from Cheers. Like the theme song goes, it's somewhere where everybody knows your name, where you can socialize in a place other than your home or work and build some community. But with the whole world accessible on your smartphone, it's kind of hard to resist the call of the couch. And it's hurting us more than we think."

Negative sentiment toward social media has been building for years, and now it’s finally boiled over,” said Mike Proulx, a director at Forrester, a market research company.

It's easy to get the idea that philosophy is largely an abstract and conceptual endeavor–studying theories that try to explain the universe, morality, or language, and then arguing until we either prove those we disagree with wrong or at least reach a smug sense of clarity. But is that all that philosophy has to offer? Back by popular demand, this month we'll be diving deeper into the reflections of **Pierre Hadot** by beginning his essay **Spiritual Exercises**. In this essay, Hadot argues that **ancient philosophers didn't just theorize about what a good life might be, but practiced it through disciplines of attention, meditation, and self-examination aimed at transforming how one sees and lives in the world**. The essay invites us to ask **whether philosophy might still serve that purpose today**. Hadot specialized in **ancient Greek and Roman philosophy--especially Stoicism, Neoplatonism, and early Christian thought**–as was known for his scholarship on **Marcus Aurelius, Plotinus, and ancient spiritual exercises**. His work has influenced many contemporary philosophers, classicists, and the modern revival of philosophy as a lived practice. As noted in the title, this will be the first of two sessions. We're splitting the text into two parts in order to give everyone a chance to fit the text into their busy lives, as well as to give us space to move more slowly through the text together. \*\*\* Below is a PDF copy of Hadot's book Philosophy as a Way of Life. This session will cover up to p.93 (ending at 3. Learning to Die). If you have trouble accessing it, send the host a message–extra copies are available.

This event will be hosted in an apartment with a well-trained dog who will be happy to meet you. If anyone has concerns about dogs, let me know so I can be mindful about keeping her from bothering you. The buzzer is Everett and Mainous—we’re on the 5th floor, apartment 16. Meeting structure: We will start with a brief summary of the key ideas Hadot presents then move to open discussion. Please read the text in advance, make highlights, and note any thoughts or questions you find interesting and compelling.

**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\.

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. This is where we meet: http://photos2.meetupstatic.com/photos/event/7/7/3/1/600_447930513.jpeg
