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.

Dear all I would like to invite you to visit together the exhibition: GIORGIO DE CHIRICO – Painting is a magical art More info can be found at the link here below : https://iicpraga.esteri.it/cs/gli_eventi/calendario/giorgio-de-chirico-dipingere-e-larte-magica/ info on Giorgio De Chirico can be found at the link here below: https://en.wikipedia.org/wiki/Giorgio_de_Chirico **Exhibition Overview** The exhibition was curated by Lorenzo Canova, professor of the history of contemporary art at the University of Molise and member of the scientific council of the Giorgio and Isa de Chirico Foundation, and is organized by the ALEDYA Foundation and the Italian Cultural Institute in Prague in cooperation with the Casa d'Arte San Lorenzo in San Miniato (Pisa) under the auspices of the Italian Embassy in Prague. The exhibition will be divided into three parts, specially designed for the impressive spaces of the institute, a major architectural complex from the late 16th and early 17th centuries. The Baroque chapel will display works that chart a very long and important period in the master's career, from the 1930s to the early 1970s, from metaphysical architecture, through vedutes of Venice to famous Italian squares. The chapter hall will display a significant selection of works dedicated to de Chirico's so-called "baroque" phase, from paintings of horses and riders to still lifes, which the artist liked to call "quiet lives". The last part, located in the foyer, will present the artist's work in the field of graphics, to which he attached great importance. Drawings, sketches, lithographs and engravings from the archive of the great printer Alberto Caprini, with whom the master had a long relationship based on mutual respect and collaboration, will be exhibited. On display will be around 60 works from important Italian and European private collections. There will be references to de Chirico's previous stays in Prague, his friendship with the great Czech painter Jan Zrzavý, and a tribute to the master by Mario Schifano, a significant figure in Italian and international art of the second half of the 20th century. Numerous information panels will guide visitors through the poetics and creative world of Giorgio de Chirico. meeting point : entrance from main door of **Italian Cultural Institute** **Vlašská 34, 118 00 Prague 1** 16 PM / on 28th March 2026 short agenda: introduction project; ice breaker visit of the exhibition sharing impressions Pizza together estimated duration: approximately 3 hours admission cost : information ( not available) A fee of 4 euro (96.96 CZK) is needed in order to confirm your attendance for the pizza ( and to book the restaurant accordingly)/ no refund in the event of not attendance of the event The fee will be used to cover unpaid bills ( if any) and is not going to be refunded at the end of the event. if you can't find the group phone at : 00420770171095 I look forward to meeting you ps please do not accept if you are not sure to come and give the opportunity for others to join

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

**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** [https://youtube.com/live/fD2cYeKp_UU?feature=share](https://youtube.com/live/fD2cYeKp_UU?feature=share)
