This meetup is for foreigners, expats, and newcomers who want to practice Czech in a relaxed and welcoming atmosphere. We will speak mostly in simple Czech, but beginners are welcome too. The goal is to gain confidence, improve your speaking, and meet new people. Come for conversation, tea or coffee, and a cozy community feel. It's free in community centre U Studánky 15.Praha 7 Organised by Diakonia.

Learning Czech can be hard and demotivating, especially when studying alone. **This meetup is a shared study session where we come together to stay focused, motivated, and make progress — each in our own way.** This is a co-learning / co-studying session, not a class. There is no teacher, no lesson, and no study material provided. Everyone comes with their own resources and studies independently, in a shared environment. 🧠 **How it works** • We all bring our own material: • textbooks • homework from a Czech course • Duolingo or other apps • reading practice • vocabulary review, etc. • We mainly work individually • We are free to: • ask questions • help each other • share tips and resources • No teacher, no formal structure, no pressure 👥 **Who is it for?** • Czech learners of all levels • Non-Czech speakers (expats, internationals) • Czech native speakers are welcome if they want to help, but this is not a language exchange ⏱ **Practical info** • Location: Cafedu 12, Škrétova 490, 120 00 Praha 2 (Metro A and C, Muzeum station) • Duration: 2 hours, or less or more, as you want • Day & time: Monday, 18:00 • Group size: small group for now • Free event — please support the café by ordering a drink ☕ If you’re learning Czech and lack motivation when studying alone, come join us — let’s find it together 🙂

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.*

Instruction level parallelism by [Ivica Bogosavljević](https://johnnysswlab.com/author/ibogi/) Instruction Level Parallelism (ILP) is the magic ingredient of a modern CPU that makes it run fast. But not all programs are equal, some have more ILP, others have less. In this talk we are going to investigate our codes from the viewpoint of ILP: which code has more ILP, which has less ILP, how does ILP affect software performance and what techniques we can use to speed up our software. Timetable: 18:00 Get together, setup, socialize 18:30 talk starts ??:?? talk ends, more socializing For those who want to join online here is the **[ZOOM LINK](https://us06web.zoom.us/j/83891473439?pwd=7HSo6db5TDdSQA72V0jVEkGMzhbZeu.1)** While you wait why not join our **[DISCORD SERVER](https://discord.gg/3FQFqkjPyc)**

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).

Zveme vás na první lokální setkání zaměřené na GitLab v Praze. Budeme mít hosty přímo z GitLabu s krátkou prezentací novinek a jejich využití v praxi.
