**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.

Zapraszamy na kolejne spotkanie planszówkowe! Mamy parę gier w spejsie, ale zachęcam przynieść również własne gry! Chętnie zagramy w coś nowego. Jest też miejsce na zostawienie gier na jakiś czas w spejsie, żeby nie musieć ich targać tutaj co tydzień. \-\-\- Zaczynamy o 19:00, ale warto sprawdzić [https://at.hs-ldz.pl](https://at.hs-ldz.pl) – być może ktoś otworzy siedzibę wcześniej.

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

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant. Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA). AoC members are invited to join this OA meetup and/or OA Facebook group ( https://www.facebook.com/groups/omnipresentatheists/ ) but are free to continue conversations on the AoC Facebook group ( https://www.facebook.com/groups/columbusatheists/ ). AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge. Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org). Omnipresent Atheists is a member of the Columbus Coalition of Reason ( http://www.ColumbusCoR.org ). Omnipresent Atheists endorses the mission of the Secular Coalition for America ( http://secular.org ). This group has been meeting every Tuesday evening for over a decade.

**New Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

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.

**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
