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?

**Naked Minds: Life Audit** **See where you truly stand & decide what’s next** Launch price: 399 CZK (regular price: 1,499 CZK) You need to register and buy [Tickets here](https://www.tixtree.com/e/life-audit-see-where-you-stand-dab2b4801eb5) Most people don’t feel stuck because they lack motivation. They feel stuck because they never clearly see where they actually are. Life Audit is a structured evening designed to help you pause and take an honest look at your current reality. Where do you truly stand right now? In your work. Your relationships. Your energy. Your direction. You won’t be pushed to “reinvent your life.” You will **see clearly. Choose consciously.** No hype. No gurus. No forced positivity. **Just clarity, ownership, and a next step that makes sense.** **WHAT THIS EVENT IS ABOUT** Your life moves in the direction of what you repeatedly choose — consciously or not. At Life Audit, you will: * Evaluate where you currently stand across the key areas of your life * Identify what feels aligned — and what doesn’t * Gain clarity on what is working and what is draining you * Define what you actually want next * Create a simple, realistic path forward This is not about pressure. It’s about awareness that leads to better decisions. **WHAT YOU’LL WALK AWAY WITH** * A clear snapshot of your current life * Honest insight into your reality * A defined next direction * Concrete action steps tailored to you * Shared momentum from people who take growth seriously You won’t leave “inspired.” You’ll leave clear. This is about implementation, not information. **HOW IT FEELS** Grounded. Honest. Clear. Like stepping back and seeing your life from above — without judgment, without drama. **See clearly. Choose consciously.** No pressure. No shame. Just clarity and forward motion. **WHO THIS EVENT IS FOR** This is for you if you: * Want clarity about where you stand * Feel slightly off-track or drifting * Are ready to stop postponing decisions * Want growth that fits real life * Prefer grounded structure over motivation hype If you’re ready to stop drifting and start choosing your path … this is for you. **WHAT THIS IS … AND ISN’T** This is not a motivational talk. No yelling. No toxic positivity. No “just try harder.” Life Audit is a structured Naked Minds experience designed to help you see your life clearly — and move forward intentionally.

**Beer, Pizza and IoT Meetup (DigiCert Special)** We would like to invite you to our next IoT Meetup at Concept Reply at the Reply offices in Munich. **Agenda** 19:00 – Securing the future Internet of Things with ML-KEM and ML-DSA (Talks by Kevin Hilscher and Daniel Stroehmann from DigiCert) 20:00 – Pizza & Networking **Description** Today’s Internet of Things (IoT) relies on a variety of protocols and communications technologies…CoAP, LwM2M, LoRaWAN, NB-IoT, Wi-Fi, Thread … many of which are not quantum-safe. While large-scale quantum computers capable of breaking current encryption aren’t yet available, the concept of “harvest now, decrypt later” is a significant concern. Now that NIST has released final versions of its first three Post-Quantum Cryptography (PQC) standards the race is on to make IoT quantum-safe. **We will explore** * What it takes to make an IoT solution quantum-safe. * The algorithms regulators, such as BSI, are recommending. * How to implement and transmit data between a device and an MQTT broker with TLS 1.3, ML-KEM, and ML-DSA using open-source tools. Please feel free to forward this invite to anybody who might like to take part. PLEASE NOTE: This Meetup will get streamed and recorded so you may get filmed by taking part. Doors open at 7PM for this one due to an event before. This event is exclusively for those with a professional background. Due to limited capacity, we reserve the right to restrict admission. Pizza, beer and seats first come first serve! :)

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)
