Hi all! My name is Cara, and I am a native English speaker from America living in Prague. This a meet up for t**hose learning English as a second language** and want the **opportunity to practice**. It will be a fun and relaxed setting where we will play games to **promote English conversations** or have some kind of activity. This club will meet **every other (two Mondays each month) Monday evening.** The goal is for each person to walk away having learned new English words and have more confidence when speaking in English. Please, bring some money if you want to purchase a coffee from Evento. **This event is sponsored by a church.** The church that sponsors this English meet up is **Církev bratrská, Bohnice** [https://www.cbbohnice.cz](https://www.cbbohnice.cz/) . We want to live lives that are reflective of Jesus. Like Jesus we want to help others in meeting a practical need, in this case that would be speaking in English. At the end of the English club, we will extend an invite to anyone who is interested in exploring faith, wants to know more about Jesus, or wants to meet up to read from the Bible. However, we will never trick you into attending and will always be honest about the content of our meetings. *You do not have to attend religious events to be a part of English Club.*

Hello Python extractors and vulnerable agents, The 35th PyData meetup will take place at **Aisle offices** (Palác Zlatý kříž, 2nd floor). As usual, the talks will start at 18:30 but we encourage you to come as soon as **18:00** to enjoy the opportunity to socialize and refresh yourselves (which you can continue doing during the break and after the talks). Our main goal is to build the community around Python and data and make it welcoming to people of various skills and experience levels. ⚡ If you are interested in giving a lightning talk (up to 5 minutes to present an idea, tool or results related at least to some degree to Python and/or data), please contact us before the event or at its beginning. **What a Single-File LLM Security Analyzer Taught Us?** **([Stanislav Fort](https://www.linkedin.com/in/stanislav-fort/), Aisle)** High-quality AI security research can uncover real vulnerabilities in critical infrastructure. AISLE is one example of this higher-signal approach, with validated findings in projects like OpenSSL and curl. At the same time, low-quality AI-generated reports are flooding open-source maintainers with false positives. How hard is it to find a security bug? We will explore that question through nano-analyzer, a deliberately simple open-source security scanner. For many vulnerability classes, the surprising core is not a complex platform, but a well-aimed LLM call wrapped in the right workflow. This simplicity has limits. The approach may miss obvious issues, hallucinate risky findings, or produce inconsistent results across runs. That is why validation, triage, benchmarking, and human judgment matter, and why the real challenge is building reliable processes around unreliable primitives. **Getting reliable text when PDFs lie and OCR fails** **([Marcela Brichtová Piptová](https://www.linkedin.com/in/marcela-brichtov%C3%A1-piptov%C3%A1-b950ba184/), Rossum)** LLMs need text as an input. So before a model can reason about a document, we have to read the text, a step often treated as the "easy part" or a solved problem. But is it? In this talk, we will explore the hidden complexities of text extraction. This is especially critical for models like Rossum's T-LLM, an encoder-only architecture which heavily relies on high-quality input. You will learn why transactional documents are sometimes surprisingly hard for OCR, why you can't always just copy-paste text from a PDF, and why text extraction is still a topic for Rossum researchers (and our customer support team).

Join **RSP Adventures** for an unforgettable day trip to the Šumava Forest, part of the largest continuous forest landscape in Central Europe. Together with the neighboring Bavarian Forest, Šumava forms what’s known as the "Green Roof of Europe" — a land of deep forests, glacial lakes, medieval castles, and untouched wilderness. Our hike will take us to two of Šumava’s most iconic and mystical sites — the glacial Černé (Black) and Čertovo (Devil’s) Lakes. Nestled among steep forested slopes, these ancient lakes are silent witnesses to the last Ice Age, and their dark waters have long been surrounded by legends and natural beauty.

PangeAI is building agent-driven geospatial intelligence for anyone, turning natural language queries into instant spatial analysis and decisions, with no GIS knowledge required. Backed by autonomous agents we're focused on use cases geospatial context drive real decisions. We're headquartered in the Bay Area with our European HQ right next door in Prague. Maps encode rich spatial context that today's AI agents largely fail to interpret. In this talk, I'll share how we're teaching agents to "read" maps in production at PangeAI starting with geospatial embeddings as a practical foundation for geo-similarity detection, then layering multi-agentic orchestration on top to generate strategic geospatial insights at scale. Along the way, I'll walk through the tooling and frameworks we've built to make all of this tractable for engineers, with real-world examples and open questions at the intersection of geospatial data and agentic AI.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
