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

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).

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.

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/.

**Latest 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 speakers for our Monthly Meetups!

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 ).

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)

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.

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!
