Hack The Box Meetup: No 16
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)

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.

8:10 PM: Announcements and break
Announcements, HR lost & found, open mic
8:30 PM: Talk 2: The Two Faces of sync.Mutex / Gaurav Gahlot, Staff Software Engineer @ IONOS Cloud
Go's sync.Mutex has two faces — one that's fast but unfair, and another that's fair but slower. 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.

Planszówkowanie w Hakierspejsie
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.

CTF-y z Hakierspejsem
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.**

Prompt vs. Paintbrush
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.
