Dzień otwarty, bez tematu przewodniego
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? Skontaktuj się z nami na czacie lub mailowo. Szczegóły znajdziesz tutaj:

Więcej szczegółów uzgodnimy na naszym chacie Telegramowym/Matrixowym:

Structured Concurrency, Virtual Threads i JDK26
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.
Hack The Box Meetup: No 18
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)

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.

CTF-y z Hakierspejsem
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.**

[HYBRID] [May] Golang Meetup
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:

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

CZSK PPUG Meetup
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.
