There's something about tango that gets under your skin. You watched it, or tried it once, and something in you probably felt really good. Because tango is connetion in the present moment. Tango Fundamentals 1 is a structured 6-week course designed to take your tango journey through the basic steps and figures of Argentine tango. This is not just about copying moves - but rather actually understanding how tango works. The connection, the lead and follow, the conversation between two people through movement. By the end of these six weeks, you'll understand the basic concepts of tango, the etiquette of milongas, how to invite someone to dance - and you'll actually be able to dance. **What's included:** * 6 weekly classes - every Monday, 75 minutes each * Bonus 4 online evenings - stretching, strength, technique and mindfulness to support your body and focus in your Tango Journey * 1 Practica at the end - a real social dance to put it all together **Investment:** €165 full price, €125 for students. There is an option for classes without an online offer. Just write me a message. Single class: €28 / student €22 **This is for you if:** * You've tried tango once and want to go deeper * You've always wanted to learn but never knew where to start * You want a real foundation, not just a one-off workshop Spots are limited - this is a small group, so everyone gets proper attention. Drop a message here or reply directly to reserve your spot. 🙏

In many organizations, APIs are treated as technical contracts — neat documentation of endpoints and payloads. But what if APIs could become something more: living expressions of the business domain itself? This talk examines how Domain-Driven Design (DDD) and modern API craftsmanship converge to establish a shared language between people and systems. We’ll walk through how techniques like Domain Storytelling, Event Storming, and Context Mapping can lead directly into OpenAPI and AsyncAPI specifications that reflect real domain intent — not just data structures. **How can LLM help?** Along the way, we’ll see how Large Language Models (LLMs) can amplify human creativity — helping teams turn visual domain artifacts into executable API contracts while preserving intent and nuance. Instead of replacing design thinking, AI becomes a collaborator in the craftsmanship process. Through practical examples, we’ll explore how bounded contexts define API boundaries, how ubiquitous language shapes resource and event models, and how contract-first design enables safe, evolutionary change. By the end, you’ll see APIs not merely as integration points, but as living domain boundaries to align architecture, business, and shared understanding. **About the speaker** [Annegret](https://www.linkedin.com/in/dr-annegret-junker-141a99a4/) is Chief Software Architect at codecentric AG in Germany. She has worked in software development for over 30 years. She worked in quite different roles and domains. She is especially interested in DDD, microservices, and everything else. She is working on a large integration project and defines APIs for partners. **The Sponsor** This time, the location, food, and drinks are sponsored by [TechTalk](https://techtalk.at/). Thank you very much, TechTalk, you rock! 🎉 This will be a joined event with the Microservices, Reactive and Distributed Systems Vienna Meetup ([https://www.meetup.com/reactive-vienna/](https://www.meetup.com/reactive-vienna/)) and it is enough to register for only one of the meetups. It is not necessary to register for both! Space is limited, so please register if you want to come. As always, we're very much looking forward to seeing you! Best regards, Daniel and Gottfried

LFU looks deceptively close to LRU: both caches evict the "least useful" item. We'll look at how the ordering rule affects data structure design. We'll discuss the algorithmic tradeoffs behind LFU and compare different implementation strategies, ending with benchmarks in C++ and Rust. Date and time: **25th of June (Thursday), 6 pm** Location: **Beograđanka, Vidikovac, 22nd floor** Address: **Masarikova 5** Online: **[C++ Serbia YouTube](https://www.youtube.com/watch?v=PwmFvXE_K9I)** To join the community discussions, we are on: * [Discord](https://discord.gg/VDUn8YtHw8) * [Telegram](https://t.me/+l7NS0GrslBMwNzI0) * [Website](https://www.cppserbia.org/) See you!

FlashAttention is one of the most important pieces of software infrastructure for both training and serving any relevant AI model on cutting-edge GPUs. Let's have a look under the hood. The paper comes with a blog post that may be easier to read: [https://tridao.me/blog/2024/flash3/](https://tridao.me/blog/2024/flash3/) Find the paper here: [https://arxiv.org/abs/2407.08608](https://arxiv.org/abs/2407.08608) We are trying out a new Location -- right at the Westbahnhof IKEA. Take the elevator to the fifth. We may relocate if it is too crowded. Please Text me if you are late and can't find us. \-\-\- Bring your own printout or pdf-on-a-gadget. If you didn't have the time to read the whole paper, it is sufficient to be able to pretend to have sort of skimmed it. \-\-\- Want to suggest a paper, an event location, or just stay in touch with regular members?

But maybe ... Maybe its worth thinking about. Not because it's broken - because it could be a little faster, a little safer, and a lot more yours. A talk about improving the parts of Flutter we stopped questioning. **19:40:** 🍕 **Food, Drinks and Socializing Break** **20:10: Become a Full + Video Stack Dev - Writing UIs is just the start** **by *[Simon Auer](https://x.com/SimonEritsch)*** What if you could use your existing Flutter skills to not only build UIs on screens, but to create visual stories ... and export them as real video files like MP4? From Spotify-Wrapped like summaries, over instructional content that evolves with your codebase, to personalized videos for tens of thousands of users ... all generated programmatically. No video editor app, no ui clicking ... just beautiful code and open source (and maybe vibe coding)! <3 Batteries included: collaboration & versioning in Git, review changes via pull requests, batch-generating variations or integrating video creation directly into pipelines and CI systems **21:00: Meeting fellow Flutternauts**, last bits of food, a drink, friendly or heated discussions (about get, riverpod and bloc ;) ) in a cozy atmosphere. **21:45 - 22:00: Wrapping up**, last drinks We are looking forward to meeting you there! **\*\*WANT TO DO A TALK?\*\*** We are always looking for (short and long) talks!

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
