F# Programming

Join us for the first meetup in 2026! ⭐️ Are you interested in the Ruby language or Ruby on Rails? Join us. We have great talks, good vibes, and yummy snacks! 😋 **Talks** \~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~ 🗣️ [Peter Solnica](https://solnic.dev/) ▶️ Structured Logging in Ruby: Where We Are and Where We're Heading 🗒️ Ruby's logging ecosystem is evolving, and there's a lot of momentum to build on. In this talk, we'll explore the current state of logging in Ruby and compare it with ecosystems like Elixir, where a more capable, well-designed logger is built right into the standard library. We'll dive into recent developments in Rails - including its new structured events API - and how they connect to the broader picture of structured logging, error handling, and tracing. Along the way, we'll build a vision for what Ruby's standard library could offer: a powerful, extendable logger that makes structured logging a natural part of every Ruby project. 🗣️ [Marie-Therese Fischer ](https://fischer.codes/) ▶️ Building Games with Ruby 🗒️ What do you end up with when you strip Rails from a Rails developer? Plain Ruby. Join me as I explore the language behind the framework through the lens of game development. By building a simple terminal game and a 2D platformer, I’ll break down the essential building blocks every game is built on - from loops and input handling to visuals. We'll look at how stepping away from the 'magic' of Rails to build games can lead to a deeper understanding of Ruby logic and application structure. 🗣️ [Christoph Lipautz](https://github.com/unused) ▶️ The Art of Testing Nothing 🗒️ Traditional CI/CD pipelines often waste significant resources re-validating unchanged code, creating a bottleneck in the development lifecycle. This session explores the results of my attempts to shift from exhaustive execution to smart omission. I'll discuss how doing nothing turns into a technical strategic advantage while maintaining confidence. **Location** **\~\~\~\~\~\~\~\~** Mariahilfer Str. 97/4, 1060 Wien **Sponsors** \~\~\~\~\~\~\~\~\~ ⭐ [Meister](https://www.meisterlabs.com/jobs/) Founded in 2006 by Till Vollmer and Michael Hollauf, Meister’s journey from start-up to scale-up has been a story of continual growth. What started with a vision to create a simple visual mind-mapping tool has become not one but two collaborative tools that help teams everywhere focus on the work that matters. Thank you to Meister for hosting and providing us with refreshments and snacks! 🙌 \~\~\~ ⭐ Looking to sponsor or give a talk? We are looking for sponsors and speakers.

**\*\*\* Enrollment and all info** [https://www.iicv.at/intermediate-classes](https://www.iicv.at/intermediate-classes)**\*\*\*** **Description:** **Come join for a journey of some of the nitty-gritty of improv performance.** We’ll work on scene work, stage presence, breaking out of our patterns, finding fun in the stillness, and stillness in the craziness of Improv. This is for improvisers who understand the foundations and concepts of improv and want that extra challenge to perform or refine their performance skills. **Teacher:** Shawn Fisher Shawn Fisher is an improviser, performer, and educator. With over 15 years of experience in improv, you can see him with The English Lovers, one of Vienna’s longest-standing improv groups, Two-Buttons Short, and with Rainbow’s Last Wish. Originally from the US, he has taught classes, workshops and led open improv sessions in Vienna since 2018, fostering community where curiosity leads the way. ​ Whether directing, MCing, or coaching at venues like Vienna’s Maestro, Shawn thrives on the spontaneity and connection of live performance—especially when leaning into the fantastical.

We need to respect current regulations in Vienna, Austria. The main priorities are to have fun and being safe. The drinks are relatively free after the game in the local pub, served to those who have shown fantastic football fair-play skills. We’ll confirm the location, the pitches, and the dressing room numbers via our dedicated Football WhatsApp group. Keep an eye out for the group messages. See you all soon.

Any misbehavior on your part, such as responding in an obscene way, fighting, or leaving the pitch is not a practical and diplomatic way of resolving the issues (it tends to create more tension and cause more problems).

This approach verifies eBPF code integrity before kernel loading, reducing vulnerabilities in observability, networking, and security tools while ensuring safe deployment in production environments.

**Contact Improvisation Day Workshop** **Paths of Remembrance – Introduction to Somatic Contact Improvisation (Open Level)** Contact Improvisation is a contemporary dance form in which we playfully explore movement possibilities through shared weight. It is physics in motion as well as a felt, moving encounter. The somatic approach opens access to the body’s inherent wisdom, supporting us in playfully building basic skills for Contact Improvisation. **You will learn:** * how movement is organized through the center and the spine (integrated movement organization) * how to organize and use your own body weight organically and efficiently in dance * how to move dynamically and three-dimensionally with a partner across different levels ✨ * **Open Level** This workshop is suitable for beginners as well as for people with prior experience. Explore how all movement is organized through the center and the spine, and how you can use the body’s original (organic or integrated) movement organization to develop a solid technique for dancing with shared weight.

Hi Running fellows, Whether you’re a walker, new to running, a semi-pro, a marathonist or a sprint star - if you want to start your weekend in an active way and enjoy the outdoors in lovely surroundings with a fun, international and multilingual group of people, you are welcome to join us! Every Saturday at 9:30 am, we meet, we run, in the magnificent Schönbrunn park, and then we go for breakfast. Want to discuss politics or the best recipes for banana pancakes? Not a problem. Not feeling social? Tune out with your earbuds - we can talk over breakfast. We are casual. You can be too. What to expect: Start by meeting Adrian, Ali, Liz, Paul and Sonia on-time at 9:30am outside the Schönbrunn U-Bahn stop (exit Grünbergstraße). (Coordinates: 48.1858130, 16.3200640) From there, we walk to the side park entrance where the “running” part begins. The important thing is that you run at your own pace. Typically, small groups of people will run at the same pace as you, so you never have to walk/run alone :) We finish one hour later, at about 10:40am, reconvening just inside the Hietzinger Tor exit. (Coordinates: 48.1858825, 16.3032647). From there, we’re off to breakfast!

If you missed us earlier, you can always go there around 10:45. We are a fun group of runners who don’t take things too seriously. We meet, chat, RUN, stretch, chat, EAT and we hang out over a beer every now and then. It's that easy. Please join us for breakfast after the run! The more the merrier. Typically we are 10-30 people, as not everyone who comes signs up on meetup. Important disclaimer: Please only run as much as you feel you can, considering the temperature, weather conditions, your own fitness etc... run and walk at your own pace as the organizers do not assume any liability for any injuries or health issues.

One of the most valuable parts of this community is the opportunity to think out loud with other product professionals. This session is built for exactly that. As we wrap up the quarter, it’s a great time to pause and reflect. What’s on track? What needs adjustment? Where could a small shift create bigger impact? Join fellow product professionals for a focused, interactive conversation designed to help you recalibrate for the next quarter. You’ll have the opportunity to share where you are, hear how others are thinking through similar challenges, and gain fresh perspective you can bring back to your team and organization. We’ll gather at 8:00AM, with discussion starting promptly at 8:15AM. 📍 First Watch - 7227 N High St Located in: The Shops at Worthington Ample parking is available. Food and beverages will be available for purchase. Start your morning with clarity and connection — we hope to see you there! ☀️

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

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!

Drake Lundstrom is presenting: Code Anywhere by Talking to your Phone Abstract: Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices?
