С голямо удоволствие ви каним на следващата ни WordPress Sofia Meetup среща, която ще бъде с маркетолога Marina Vassilyovska. Марина е подготвила тема по изключително наболял за много бизнеси и създатели на съдържание въпрос – какво е бъдещето на блоговото съдържание, когато търсачката се превърне в наш конкурент? По време на лекцията ще разберем: 👉 Какво се случва с класическия блог през 2026 година? 👉 Какво представлява "The Great Decoupling" в контекста на онлайн съдържанието? 👉 И най-вече: ако AI Overviews изяждат все по-голямо парче от Google трафика, а клиентите ви откриват основно през него, какъв е следващият ви ход? Ако разчитате на органичния трафик за развиване на бизнес проектите си, тази лекция е точно за вас. Заповядайте да обсъдим накъде отива индустрията!

*🦞* Cogito Ergo Creo *🦞* Second gathering of OpenClaw Bulgaria. This time — we go local. On April 4th, Anthropic blocked Claude Pro and Max subscriptions from being used through OpenClaw and other third-party agent frameworks. The message was clear: if you want to run agents your way, you need to own your infrastructure. So that's exactly what we'll do. 🧠 Mental — Why local matters. What happened with Anthropic's decision, what it means for the agent ecosystem, and why running your own LLM isn't just a backup plan — it's freedom. 💻 Demo — Setup & run. Live walkthrough: setting up and running a local LLM from scratch. Models, hardware, tools, performance. No cloud, no API keys, no permission needed. 🔥 Live — Your turn. Bring your laptop, your project, your questions. Build something, break something, ask anything. Open floor. Who is this for? Developers, makers, entrepreneurs, and the simply curious. Whether you've been self-hosting for years or just want to understand what "running local" means — if you like building things, you belong here. Language: English + Bulgarian — whatever flows naturally. 📍 Location: SOHO — HOLISTIC Room, 4 Iskar Street, Sofia 1000 (near Serdika metro station) 🕐 Start: 17:00 🌐 www.openclaw.bg 💬 discord.gg/qu4gusnZd3 This is a recurring meetup — every first Thursday of the month (moved this month due to holidays). Come once, come always. Hosted by Alex Alexiew & Aria 🤖 ——— 🇧🇬 Български Cogito ergo creo. Втора среща на OpenClaw Bulgaria. Този път — ставаме локални. На 4 април Anthropic блокира използването на Claude Pro и Max абонаментите през OpenClaw и други агентни платформи. Посланието беше ясно: ако искаш да пускаш агенти по свой начин, трябва да притежаваш инфраструктурата си. Точно това ще направим. 🧠 Mental — Защо локалното има значение. Какво се случи с решението на Anthropic, какво означава за екосистемата на агентите и защо да пуснеш собствен LLM не е просто резервен план — а свобода. 💻 Demo — Настройка и стартиране. На живо: инсталация и стартиране на локален LLM от нулата. Модели, хардуер, инструменти, производителност. Без облак, без API ключове, без разрешение. 🔥 Live — Вашият ред. Донесете лаптоп, проект, въпроси. Създайте нещо, счупете нещо, питайте каквото искате. 📍 Локация: SOHO — зала HOLISTIC, ул. „Искър" 4, София 1000 (до метростанция Сердика) 🕐 Начало: 17:00 🌐 www.openclaw.bg 💬 discord.gg/qu4gusnZd3 Срещаме се всеки първи четвъртък от месеца (този месец преместен заради празниците). Елате веднъж, останете завинаги.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City. He has worked there for 17 years, serving previously in the roles of Data Analyst, Programmer, and Operations Coordinator. Prior to working at South Western, he worked as a Systems Engineer at Pinnacle Data Systems in Groveport. He graduated in 2005 from The University of Toledo with his Bachelor’s in Computer Science and Engineering, and a minor in Mathematics. Robert resides in Obetz with his wife, and their 15 and 12 year-old daughters. He was also just elected to his 3rd four-year term on the Obetz City Council.

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
