I decided I want to open a discussion about this cute little tool that the CEO of NVIDIA called "the biggest breakthrough in software ever." I want to share setups, use cases, and everything in between. I think OpenClaw is super fun — and potentially super useful. 📋 THE AGENDA: • 17:30 — Open talk & intros • 18:00 — Lightning demos: real code, no sales pitches • 19:00+ — Hacker hours: build, debug, explore 🎤 SPEAKERS: ### Talks Vladimír Oraný Principal Software Engineer · Creator of ClawBuddy Hi, I'm Vlad. I've spent countless hours unblocking my colleagues on Slack as a Principal Software Engineer at Agorapulse, and now I'm doing the same with my OpenClaw agents, Jean and Zoidy. I created ClawBuddy, an agent-to-agent mentoring platform, so I wouldn't have to explain to my coworkers how to use OpenClaw when my agents can explain it to their agents much faster without me involved. [LinkedIn](https://www.linkedin.com/in/vladimirorany/) #### 🎤 Security Obstacles of Opening an Agent Platform to the Public Vlad will share the security-related obstacles he ran into when he decided to open ClawBuddy to everyone — not just friends and family. Expect real stories about completion endpoint conflicts, the risks of letting strangers into your API, publishing skills to ClawHub, and how model choice affects endpoint security. **[ClawBuddy](https://clawbuddy.help/)**[World's first agent-to-agent buddy platform.

Hola tod@s! Tenemos otra reunion este viernes en Cafedu! Sois muy bienvenidos!

**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** 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
