Zen w Hackierspejsie
Zapraszamy na trzy dwudziestopięciominutowe rundy medytacji, w trakcie których będzie okazja doświadczyć swojej pełnej obecności w tym-co-jest z-chwili-na-chwilę.
Rundy rozpoczynamy o 18:30, 19:00 i 19:30 - można dołączyć do dowolnej z nich lub odłączyć się w trakcie przerw pomiędzy nimi. Prosimy o przyjście chwilę przed rozpoczęciem rundy, ponieważ startujemy punktualnie.
Medytacje odbywają się w każdy czwartek na ul. Zielonej 30 w Łodzi w lokalu HSŁ w głębi bramy. Przy bramie prosimy dzwonić pod numer: 42 203 20 50.
Spotkania są otwarte i wszyscy są mile widzani. Jeżeli chcesz zobaczyć, czy medytacja to coś dla Ciebie, temat jakoś z Tobą rezonuje, a może już praktykujesz, przychodź!
Zorganizujemy coś, na czym można usiąść, ale dobrze jest wziąć ze sobą swoją poduszkę do siedzenia lub matę.
Do zobaczenia!

AWS User Group KRK meetup #76 with Cloudinary
AWS meetups are back in town! This chapter is the 1st one this year and dedicated to **S3.** But we look on the storage from completely different angles:
**From Developer's to Penetration and Security perspective.**
More info soon, and the meantime we reveal topics, and...
🗓 **Save the Date**: Mark your calendar
🍕 + 🍺 = Let's gather around pizza and beer at **Hevre**
or
Watch the stream on [YouTube (Link)](https://youtube.com/live/Tx7lmDVTVKo)
Hosted by:
**Maciej Lelusz**, AWS Hero
AWS Community Builders: **Maria Kmita & Pawel Kusinski**
🎤 **Speakers**:
〰️ *„*"Optimizing S3: A Million-Dollar FinOps Journey"
**Avihay Tsayeg,** Senior Staff DevOps Engineer, Cloudinary
〰️ *„UnS3cure - Buckets full of holes"*
**Paweł Kusiński,** Penetration Tester and Security Researcher
💡 Details about Speakers & Talks💡
**Avihay Tsayeg:**
joined Cloudinary five years ago and is a key member of the Infrastructure group, where he leads the FinOps domain. With over 20 years of experience in software development, specializing in the DevOps–FinOps intersection, Avihay brings deep expertise in cloud cost optimization.
☞ will speak about:
In his talk, he will share actionable strategies for mastering resource cost management within AWS S3.
**Paweł Kusiński:**
Penetration Tester and Security Researcher focused on app and cloud security. His work includes penetration tests and infrastructure audits across a wide range of IT projects. Passionate about knowledge sharing, he leads workshops, gives conference talks, teaches at universities, and is an AWS Community Builder.
Outside of work, he plays CTFs as a member of justCatTheFish and has an unhealthy habit of buying too many Legos - despite having absolutely no space left for them.
☞ will speak about:
Time goes by, AWS keeps adding new security features, and yet year after year, we hear about more data leaks and breaches involving S3 buckets. Data spills by the terabyte, companies apologize, and shortly after, the cycle repeats.
How does this keep happening? What is the core problem? How do attackers find their targets? We’ll walk through the most common methods and configuration mistakes - and if time allows, we’ll try to secure everything properly as well! And who knows - maybe we'll uncover a million-dollar leak during the presentation?

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.

How to Move on From the Past and Feel Happy
In this local meeting, you will discover knowledge that you can use to get over the past.
The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories.
When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!
