Zapraszamy na trzy dwudziestopięciominutowe rundy medytacji, w trakcie których będzie okazja doświadczyć swojej pełnej obecności w tym-co-jest z-chwili-na-chwilę. Rundy rozpoczynamy o 18:30, 19:00 i 19:30 - można dołączyć do dowolnej z nich lub odłączyć się w trakcie przerw pomiędzy nimi. Prosimy o przyjście chwilę przed rozpoczęciem rundy, ponieważ startujemy punktualnie. Medytacje odbywają się w każdy czwartek na ul. Zielonej 30 w Łodzi w lokalu HSŁ w głębi bramy. Przy bramie prosimy dzwonić pod numer: 42 203 20 50. Spotkania są otwarte i wszyscy są mile widzani. Jeżeli chcesz zobaczyć, czy medytacja to coś dla Ciebie, temat jakoś z Tobą rezonuje, a może już praktykujesz, przychodź! Zorganizujemy coś, na czym można usiąść, ale dobrze jest wziąć ze sobą swoją poduszkę do siedzenia lub matę. Do zobaczenia!

Azathoth opętał nasz spejs - dziwne koszmary, przerywające Wi-Fi i te sprawy. Teraz musimy tworzyć melodie chwalące tego przedwiecznego boga, by nie oszaleć (co najmniej nie bardziej niż zwykle). Spotkanie dla wszystkich zainteresowanych muzyką i tworzeniem muzyki (jakiejkolwiek). Przewidziane jest wymienianie się wiedzą i doświadczeniami oraz wspólne/indywidualne eksperymenty. Nie jest wymagana żadna wiedza z zakresu muzyki - organizatorzy też nic nie wiedzą i dopiero zaczynają. Przynieście własne instrumenty i/lub laptopy. Jeżeli masz problem z wejściem, zadzwoń na 42-203-20-50 albo wejdź na naszego czata (patrz poniżej). Numer domofonu to 100. Potrzebujesz więcej informacji? Skontaktuj się z nami na czacie lub mailowo. Szczegóły znajdziesz tutaj: [https://lodz.hackerspace.pl/](https://lodz.hackerspace.pl/) Więcej szczegółów uzgodnimy na naszym chacie Matixowym: [https://matrix.to/#/#hs-ldz:hackerspace.pl](https://matrix.to/#/#hs-ldz:hackerspace.pl) lub Telegramowym: [https://t.me/hakierspejs](https://t.me/hakierspejs)

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/cbus-hug-2026/
