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.

Franklin Park Conservatory and Botanical Gardens Free Communal Garden Class Series GROWING MUSHROOMS In this class, we will discuss how to raise mushrooms on logs outdoors as a way to raise food in parts of your yard that are usually too shady to grow vegetables or other crops. We will discuss what mushroom species can be cultivated, what tree species they can grow on, and demonstrate how to prepare and inoculate the logs. By following these steps, you can have your own bountiful mushroom harvest! APRIL 27 | 6:00-7:30 PM | WELLS BARN 1851 E BROAD ST, COLUMBUS, OH 43205 INSTRUCTOR: MARC AMANTE Mare Amante is an Agriculture and Natural Resources Extension Educator with Central State University who is also currently serving as CSU Extension's Agriculture and Natural Resources Interim Program Leader. He has worked on and managed diversified vegetable farms across the Midwest and currently owns and operates an urban farm here in Ohio where he raises microgreens, vegetables, raspberries, and log-grown mushrooms for sale to local markets and restaurants.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services) Sign up also accessible via [Transform Labs Luma](https://luma.com/55umjqta)

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
