Hakierspejs spotyka się na żywo w siedzibie stowarzyszenia! Zapraszamy wszystkich zainteresowanych naszą aktywnością. Uczestnictwo jest darmowe, rejestracja nie jest obowiązkowa – wystarczy po prostu przyjść. Nie mamy żadnego konkretnego planu: po prostu zbieramy się i haczymy - co komu przyjdzie do głowy. Zaczynamy o 19:00, ale warto sprawdzić [https://at.hs-ldz.pl](https://at.hs-ldz.pl) – być może ktoś otworzy siedzibę wcześniej. Jeżeli masz problem z wejściem, zadzwoń domofonem przy bramie od ulicy na nr 100, zadzwoń telefonem na 42-203-20-50 albo wejdź na naszego chata (patrz poniżej). Potrzebujesz więcej informacji?

To jest warsztato-spotkanie by przećwiczyć i zajrzeć w głąb "Structured Concurrency", które w JDK26 ma swoje "6th preview" - [JEP 525: Structured Concurrency (Sixth Preview)](https://openjdk.org/jeps/525). Przy okazji oczywiście wątki virtualne - tutaj chciałbym wejść nawet na poziom bytecode żeby dokładniej ogarnąć co tam się dzieje. Do tego Scoped Value (finalne) i Lazy Constants - [JEP 526: Lazy Constants (Second Preview)](https://openjdk.org/jeps/526) Skupimy się tym razem na kilku JEP-ach ale za to dokładniej i dogłębniej także zapraszam.

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.

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**: *Simon Schulte* is a Tech Lead with nearly a decade of experience building scalable backend systems across fast-paced product companies. With a background in business informatics and a passion for Golang, cloud infrastructure, and DevOps, he has spent his career solving complex engineering challenges. He is particularly excited about leveraging AI and LLM workflows to eliminate the tedious, repetitive work that slows developers down — think tech debt, boilerplate, and documentation — so engineers can spend their energy on what actually moves the needle. For Simon, AI isn't about replacing developers; it's about giving them back their time. *Daniel Peralta Madriz* is a backend engineer from Costa Rica with around 6 years of experience working with Golang, although, sadly, he's been spending most of his time lately working with Node.js :(. He is interested in distributed systems, scalability, and developer experience, and is currently experimenting with how to leverage LLMs to safely and autonomously execute repetitive tasks. *Michael Morgen* is a Platform/infra engineer by day, runtime and network optimizations by night. Join in person at: **Talon.One** Talon.One is the incentives engine behind 300 of the world’s most-loved brands, unifying loyalty and promotions on a single flexible platform. Their customers run millions of real-time incentive decisions across markets, channels, and use [cases.As](http://cases.as/) incentives become more strategic than ever, they are continuing to raise the bar for what businesses can build and how fast they can build it Wiener Str. 10, 10999 Berlin https://maps.app.goo.gl/8eMjgWes1E4TBA3c7 or virtually at: https://www.youtube.com/live/qh__TQ1bMF0?is=hw21pk0ZE3HGyaaT *** Agenda 10:49 PM: Networking Networking over drinks and food 7:30 PM: Welcome Welcome words from the organizers 7:35 PM: Talk 1: Go-ing Against the Chaos: Deterministic LLM Workflows / Daniel Peralta Madriz (Backend developer) & Simon Schulte (Techlead of Webhooks and Notifications) @ Talon.One LLMs are powerful, but “it works most of the time” isn’t good enough for production. In this talk, we’ll walk through how to design deterministic workflows around non-deterministic models using Go. From structured iteration loops to validation steps and guardrails, you’ll learn how to move beyond prompting and start engineering reliable LLM-powered systems 8:10 PM: Announcements and break Announcements, HR lost & found, open mic 8:30 PM: Talk 2: About Go Memory Allocator / Michael Morgen, Platform/infra engineer @ Mirantis A short talk about how Go gives memory to your program. We will look at the main allocator parts, why small allocations are usually fast, when Go asks the OS for more memory, and a couple of simple examples where this knowledge helps performance. 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-may-golang-meetup-1/.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

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.
