**25 marca 2026** o **18:00** spotykamy się w **IndieBI**, **Piotrkowska 157A**, Hi Piotrkowska na prezentacjach: "Logging Module Adventures" oraz "Home Assistant in Action: Automate, Customize, Control". To dobry moment, żeby wpaść po konkretną wiedzę techniczną, a przy okazji poznać ludzi z lokalnej społeczności Python Łódź. 🗓️ Jak wygląda ten wieczór? Zaczynamy od prezentacji i pytań do prelegentów, w przerwie szybko przechodzimy do rozmów w mniejszych grupach, a po części oficjalnej wiele osób zostaje jeszcze na dalszą integrację i techniczne dyskusje. 👋 Dla kogo jest to spotkanie? To spotkanie jest dla osób technicznych z Łodzi, które chcą poznać Python Łódź od środka, ale też dla tych, którzy dopiero sprawdzają, czy taki meetup jest dla nich. Jeśli interesuje Cię Python, narzędzia developerskie albo po prostu chcesz posłuchać konkretnych prezentacji i pogadać z ludźmi z branży, odnajdziesz się tutaj bez problemu. 🎤 Prelekcje Tego wieczoru skupiamy się na praktycznych tematach, które powinny zainteresować zarówno osoby pracujące z Pythonem na co dzień, jak i tych, którzy chcą zobaczyć realne przykłady z projektów i codziennej pracy. 1. **Logging Module Adventures** \- Konrad Gawda Logging module seems a little bit odd. If you would like to understand its logic - join me on my journey into the depths of Python logging. I will share learnings from my own adventure, driven by curiosity and need to add context to long running tasks' logs. 2. **Home Assistant in Action: Automate, Customize, Control** \- Jarek Śmietanka Discover how Home Assistant lets you take full control of your smart home, from lights and climate to music and hydroponics. This talk covers the project's open-source philosophy, vast ecosystem, and thriving community, alongside a real-world developer journey of setting up, securing, and customizing Home Assistant in a personal home environment. You'll see practical examples of automation, integrations, dashboards, and remote access, plus insights on balancing flexibility, privacy, and complexity. Whether you're a Python developer or a tech enthusiast, this session will give you inspiration and concrete ideas to start or improve your own smart home setup 🕒 Agenda 18:00 - Rozpoczęcie i sprawy organizacyjne 18:15 - Prezentacja 1 19:00 - Przerwa 19:30 - Prezentacja 2 20:15 - Networking 🔗 Gdzie nas znaleźć? ➡️ Oficjalna strona: https://pythonlodz.org ➡️ Meetup: https://www.meetup.com/python-lodz ➡️ Discord: https://discord.gg/jbvWBMufEf ➡️ Facebook: https://www.facebook.com/pythonlodz ➡️ LinkedIn: https://www.linkedin.com/company/python-lodz ➡️ Instagram: https://www.instagram.com/pythonlodz ➡️ YouTube: https://www.youtube.com/@pythonlodz

Spotkania z serii wymiany wiedzy podczas wspólnego rozwiązywania zadań CTF – jest to świetna zabawa pozwalająca równocześnie rozwinąć wiedzę w zakresie cyberbezpieczeństwa. Poziom trudności CTF-owego zadania ustalimy na początku spotkania. Najprawdopodobniej wybierzemy coś z platformy Hack The Box. Spotykamy się **co tydzień w środę o 19:00.** \-\-\- Zaczynamy o 19:00, ale warto sprawdzić https://at.hs-ldz.pl – być może ktoś otworzy siedzibę wcześniej. Jeżeli masz problem z wejściem, zadzwoń na 42-203-20-50 albo wejdź na naszego chata (patrz poniżej). Potrzebujesz więcej informacji? Skontaktuj się z nami na czacie lub mailowo. Szczegóły znajdziesz tutaj: https://lodz.hackerspace.pl/ Więcej szczegółów uzgodnimy na naszym chacie Telegramowym: https://t.me/hakierspejs

At the meetings we try to expand our knowledge in cybersecurity by solving CTF (Capture The Flag) on the HackTheBox platform. We meet every 2 weeks on Wednesday. We invite all interested people, regardless of their level! We do not have an agenda for the meeting, we will determine during which machine we will do. We focus mainly on practice, so you need to actively participate in the meeting: * bring your laptop with you * prepare a virtual machine with Kali Linux (or any system you like, but systems with the Linux kernel will be best) \-\-\- How to find us If you have trouble getting in, call 42-203-20-50 or go to our chat room - https://t.me/hakierspejs.

**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

We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia. * **Topics**: * **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article. * **Images**: Adding images using the img tag and attributes like src, alt, width, and height. * **Multimedia**: Embedding audio and video content using the audio and video tags. * **File and Folder Structure**: Best practices for organizing project files and managing file paths. * **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file. **Class 3: Forms and User Input** This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input. * **Topics**: * **Form Basics**: Using the form element, action and method attributes. * **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit). * **Form Elements**: Utilizing label, textarea, select, option, and button. * **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern. * **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation. **Class 4: Introduction to CSS3 and Basic Styling** The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible. * **Topics**: * **CSS Fundamentals**: The role of CSS, selectors, properties, and values. * **Integrating CSS**: Using inline, internal, and external style sheets. * **The Box Model**: Understanding margin, padding, border, and content for basic layout. * **Basic Styling**: Changing colors, fonts, and text alignment. * **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels. * **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.
