Getting Organized

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.

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/.

Pojďme se pravidelně potkávat a sdílet zkušenosti z Power Platformy, co nás na ní baví, co nás trápí a co nového zajímavého přichází. A pokud už nám to někde reálně běží, pochlubme se, jak to funguje nebo nefunguje. Témata jsou primárně Power Automate, Power Apps, Power Pages, Power BI, Copilot Studio, Dynamics 365 a Dataverse. Budeme rádi i za méně pokročilé příspěvky, protože většinou jsme velmi hluboko v technických detailech. **Lokalita:** Fyzicky v Microsoftu v Praze Vyskočilova 1561/4a, Praha 4, 140 00 Místnost Morava Případně online na [https://ppug.community/stream](https://ppug.community/stream) **Jazyk:** čeština **Agenda:** [https://ppug.community/agenda](https://ppug.community/agenda) **Přihlašte vlastní příspěvek:** [https://ppug.community/sessions](https://ppug.community/sessions) **Link na stream:** [https://ppug.community/stream](https://ppug.community/stream) **Občerstvení:** Bagety **Úroveň:** 100-300 Tak si prosím naplánujte čas ve svých kalendářích a přijďte, pokud bude chuť a čas, tak si po meetupu určitě můžeme sednout na pivo.

**Building a great product is one thing—building momentum behind it is another.** Join **Senior Product Manager Adam Solaiman** and **User Experience Manager Tyson Smith** for a behind-the-scenes look at what it takes to turn complex ideas into scalable products inside large organizations. In this session, they’ll share how teams move from ambiguity to execution—navigating organizational complexity, aligning stakeholders, and continuously evolving products after launch. You’ll walk away with insights on how to: * Build and sustain momentum across teams * Adapt to changing priorities without losing direction * Scale products thoughtfully in complex environments Whether you're driving a new initiative or growing an existing product, this conversation will give you practical strategies to keep things moving forward. Come connect, learn, and swap stories with fellow product professionals. \-\-\- Food and drinks will be provided by Switchbox, our generous host. Free parking will be available at the front and back sides of the Switchbox Office.

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, 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 chemical imbalance in your brain due to some nebulous chemical reactions 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. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. 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 Dianetics and Scientology Life Improvement Center of Central Ohio.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.
