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. Need more information? Contact us via chat or email. Find details here https://lodz.hackerspace.pl/

Już 15 kwietnia 2026 o 18:00 zapraszamy do Łodzi na kolejne spotkanie Microsoft Azure User Group Łódź — nowy rok, nowe inspiracje i solidna dawka chmurowych innowacji! 🥳☁️ 📅 Kiedy? 15 kwietnia 2026, godz. 18:00 📍 Gdzie? Hi Piotrkowska, ul. Piotrkowska 157A (obok Stajni Jednorożców), Łódź 👉 Dlaczego warto? 🤝 Networking z pasjonatami chmury 💡 Nowe inspiracje i realne case’y 😄 Luźna atmosfera i konkretna wiedza 🙏 Wielkie podziękowania dla Sii Poland za udostępnienie świetnej przestrzeni! 🎤 Agenda: 🔹 Sesja 1 🧠 „Jak budować skalowalne rozwiązania w Azure Databricks: podróż z notebooków do pakietów” 👩‍💻 Martyna Sikorska Notebooki to świetny start w Data Engineeringu, ale wraz ze skalą projektów pojawiają się wyzwania: brak modularności, trudne testowanie i zarządzanie kodem. W tej sesji zobaczysz: ✅ jak przejść z notebooków do pakietów w Databricks ✅ jak uporządkować kod i repozytorium ✅ jak pracować w VS Code (venv, testy, struktura projektu) ✅ jak uniknąć typowych błędów Idealne dla osób, które chcą wejść poziom wyżej w pracy z danymi 🚀 🔹 Sesja 2 ⚙️ „Implementing DevOps Practices for Azure Infrastructure” 👨‍💻 Tomasz Pęczek DevOps to temat, który znamy wszyscy… ale wdrożenia często kończą się na półśrodkach 😅 Podczas tej sesji dowiesz się: ✅ jak zbudować sensowny pipeline dla infrastruktury Azure ✅ jak podejść do CI/CD, testów i deploymentów ✅ jak połączyć Azure i GitHub w praktyczne rozwiązania ✅ jak przełożyć DevOps z teorii na realne działanie 🔗 Rejestracja: [dodaj link jeśli masz] #Azure #MicrosoftAzure #AzureUserGroup #Łódź #DevOps #TechEvent #SII #CloudCommunity #HiPiotrkowska #EventDriven Do zobaczenia! 👋 Andrzej Kokociński

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.

Hello Gophers, Welcome back for another year of Go talks and networking! Would your company like to host our meetup? Let us know! If you'd like to give a talk - submit your proposals here: http://goo.gl/forms/54YvJT223F All talk formats work: short talks (5-10 min) as well as regular length (25 min). If you have more ideas - talk to us at the Gophers slack: https://invite.slack.gobridge.org/ in the #berlin channel, and follow us on twitter: https://twitter.com/gdgberlingo Speakers: *Kiril Vuchkov* is Director of Software Engineering at Vay, where he leads the mobility organization across mobile, web, and backend systems, with Go at the core of the platform. He joined Vay as a Principal Backend Engineer, helping design and build a greenfield microservice architecture powering a driverless mobility service built on Vay’s proprietary remote driving technology. He later moved into leadership, focusing on technical strategy, system architecture at the organizational level, and team development. Previously, he was a Tech Lead at Uber, where he worked on large-scale distributed systems using Go, Python, and Java." *Gaurav Gahlot* is a Staff Software Engineer at IONOS Cloud where he primarily works with Go, and Kubernetes. Outside work, he organizes Cloud Native Berlin meetups and maintains the CNCF Akri project. He is also having an affair with Rust. Join in person at: **Vay** Vay’s product combines teleoperation software and hardware to power a deliverable car rental service, where trained drivers remotely bring vehicles directly to customers on demand.

Most developers never see the switch happen. In this talk, we'll explore how mutex work under the hood and how the runtime decides which face to show. Through a series of benchmarks, we'll observe mutex behavior under increasing contention and across different core counts to see both modes in action. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-april-golang-meetup-2/.

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.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Dodgeball is back again! If you’ve been wanting to come out, this is an easy one to join. We’ll be playing for about 1.5 to 2 hours, you do not need to bring any equipment, and no experience is needed. We use a specific set of rules and equipment to make the games run better and keep them fun for everybody, not just people who already know how to play. If it rains, the event will be canceled.

We’re bringing back Adult Field Day. Last year was a good mix of competition and just hanging out, so we’re doing it again with some new games mixed in. Think team-based challenges, simple races, and a few things inspired by game shows. You don’t need to be athletic. Most of the fun is just being part of a team and getting to know people you wouldn’t normally talk to. The goal isn’t really winning. It’s meeting people, laughing a bit, and leaving knowing a few more names than when you showed up. If you stick around after, we’ll have a potluck, a bonfire, and a couple comedians in the evening. Bring: * Something to share for the potluck * Clothes you can move around in A small contribution helps keep events sustainable and ensures those who RSVP actually show up. Include your Meetup name + event name in the note. Please send $2 per person to guarantee your spot. Venmo (preferred) or PayPal @WiseUnlimitedLLC Actual links in comments below! Include your Meetup name + event name in the note.

Come hang out to shop, sip + stroll through [Old Worthington](http://www.experienceworthington.com/)\- an outdoor event along the sidewalks of High St to kickoff the summer shopping season\. The shops will be open late\, store fronts will be decorated and people will be out on the town ready to start spreading warm weather cheer\!\! **START**: (6pm and earlier) at Graeters Ice Cream shop in the heart of it all. **NEXT**: about 6:15pm, we'll take a stroll and shop merch and homemade food tents. I'd love to introduce you to a new cafe, [Joyas](https://www.eatatjoyas.com/), along the stroll! (It will be too busy for us all to sit and eat so I'd recommend ordering to go) **FINALLY**: about 7pm, we'll settle in at House Wine (next to Graeters) for wine sampling and to enjoy our fresh eats! **PARKING**: Free Public Parking behind House Wine, behind Joyas and street parking.
