Please register here: https://hazelcast.com/resources/resilient-java-in-production-meetup/ ### Modern Java systems don’t fail all at once. They fail under load, during warmup, and sometimes days after a “successful” zero-downtime deployment. Join us for an evening focused on real-world resilience in production Java systems, from JVM performance stability to the hidden risks of mixed-version state during rolling upgrades. Come for the talks, stay for the conversations. Food, drinks, swag, and a LEGO® raffle included. ### **Special Guest: Simon Ritter** Java Champion and Deputy CTO at Azul, Simon Ritter shares how to make JVM performance more resilient by reducing latency risk from GC, warmup, and JIT behaviour without changing application code. ### **Hazelcast Session** Zero-downtime rolling upgrades in distributed Java systems are hard when multiple versions of the same service and data model must run concurrently and share state. Using Hazelcast and Hazelcast Compact Serialization, we’ll show practical Java examples and tests that demonstrate how mixed versions behave and how to make those upgrades resilient in real systems. ### **What’s in Store?** * Two technical talks on resilience in production Java systems * Food & drinks included * Swag + LEGO® raffle * Networking with the local Java community Please register here: https://hazelcast.com/resources/resilient-java-in-production-meetup/

# Beginners Hands-On Workshop: Breaking Down OpenClaw: From Minimal Installation Mode to Full-Featured Installation Mode w/ Your Own Custom Skills & More... **Registration to this event is only valid through the Luma platform:** [https://luma.com/it7a6h53?utm_source=meetup-dot-com](https://luma.com/it7a6h53?utm_source=meetup-dot-com) Hello code campers! Since **OpenClaw**, both as a project and as a tech movement, is growing, and since there is so much happening in this space, we've decided to dedicate the next **FreeCodeCamp \| AI** almost entirely to **OpenClaw,** especially following the success of the previous event. This is quite relevant since AI is moving soooo fast nowadays, making everyone scratch their heads confused while making some feel overwhelmed or have a small sensation of AI news fatigue. We will try to break down what this whole project is all about and whether or not all the hyperbolic statements about what this system can do are true. The aim for this workshop is to go through the setup process (it will hopefully take less time compared to last time because the maintainers of this project are constantly improving things), focusing on how to install the agent not only locally (virtualised, of course) but also in the cloud. We will probably look at AWS and GCP with the caveat: if you have your own server, which we encourage you to look into, the same will apply. This will be our **6th** event in our series of **local-first, open-source** AI events; therefore, we will try to focus on building a setup that doesn't depend on Big Tech but on smaller open-source tech instead. People who already have OpenClaw installed will be guided to customise it to use local LLMs or at least privacy-first cloud-based AI systems (that is because an individual's private ideas and personal project are their personal moat). At the end, we will be looking at what **SKILLS** are in the context of agents, how to build them, and if we have time, we will look at use cases for OpenClaw or, alternatively, look at emerging open-source AI agent toolkits like Pi. This workshop is open to all levels, from beginners to experts. Bring your laptop (make sure it's fully charged as local LLMs tend to be power-hungry), and don't forget to bring your coding gear (hoodie). This workshop will be accompanied by a guest speaker (full details TBA). *** ## Prerequisite First and foremost**, VERY IMPORTANT**, a VM (Virtual Machine) system like Docker/UTM for MacOs or WSL for Windows. Lastly, a local install of Ollama / LMStudio (but if you don't have any of that, don't worry, come a bit early and we will help set you up). If you want to take a quick look at the slides from the previous events fell free to do so: [https://andysign.github.io/ai-london-01/](https://andysign.github.io/ai-london-01/) (Ollama); [https://andysign.github.io/ai-london-02/](https://andysign.github.io/ai-london-02/) (LangFlow, not really related but still) [https://andysign.github.io/ai-london-03/](https://andysign.github.io/ai-london-03/) (private RAG w/ Anything LLM) [https://andysign.github.io/ai-london-04/](https://andysign.github.io/ai-london-04/) (AI-native browsers) [https://andysign.github.io/ai-london-05/](https://andysign.github.io/ai-london-02/https://github.com/andysign/ai-london-05) (OpenClaw basics) *** ## Agenda for the evening (Subject to change) **18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. **18:30 - 18:45 Introductions (What is Local-First?)** Intro and a bit of audience engagement **18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). **19:45 - 20:15 Guest Speaker (TBA)** **20:15 - 21:00 Networking** **21:00 - Closing remarks and follow-up** **END:** Carry on the fun at a nearby pub which is right @ the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**. [Encode Club ](http://encode.club)has spent over five years fostering a global community of developers, researchers, and founders in Web3, AI, and emerging technologies. The [Encode Hub](http://hub.encode.club) brings everything together under one roof, providing a dedicated environment for collaboration and innovation through meetups, co-working, and in-person events.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

We thought of one of the interesting things that can be enjoyed at this time of the year. We will be meeting at Immaculate Conception Catholic Church for a "Fish Fry" in Marian Hall on Friday, March 27th at 5:00 PM. It might be fun for you to experience what has become a tradition on the Fridays before Easter. They will have fried fish or baked fish, French fries and Cole slaw, as well as beverages, all for $16.00 for adults. They will have other beverages and desserts available for sale, as well. We have never tried this, and sometimes there are quite a few people at these events so we hope that we will be able to find each other easily. I'll try to have signs outside Marian Hall that Identify our group. We hope to have you join us!
