Hack The Box Meetup: No 21
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)

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.**

## Dołącz do Microsoft Build Community Event we Wrocławiu! 🚀
Dołącz do społecznościowego wydarzenia dla deweloperów, skupionego wokół nowości z konferencji Microsoft Build! Tym razem wchodzimy na wyższy poziom pracy z AI i od samego początku bierzemy na warsztat wdrażanie, monitorowanie oraz uczenie agentów sztucznej inteligencji w środowisku produkcyjnym.
Agenci AI rzadko zawodzą podczas demówki – prawdziwym testem jest dla nich produkcja. Podczas tego spotkania skupimy się w całości na praktycznym warsztacie z wykorzystaniem Microsoft Foundry. Niezależnie od tego, czy dopiero eksperymentujesz z AI, czy wdrażasz już zaawansowane rozwiązania – to intensywne spotkanie pozwoli Ci zrozumieć, jak skutecznie optymalizować, oceniać i bezpiecznie wdrażać produkcyjne systemy agentowe.
***
### 🗓️ Format wydarzenia
Wybrany format: Pełny Warsztat Hands-on (Full Workshop)
Poziom zaawansowania: (200) Intermediate Średniozaawansowany
Łączny czas: około 3 godziny (z przerwą na pizzę)
Miejsce spotkania (GlobalLogic, Strzegomska 48a, Wrocław) jest w pełni przystosowane do pracy warsztatowej: stoły, gniazdka oraz stabilne Wi-Fi będą dostępne dla wszystkich uczestników z własnymi laptopami.
***
### 📅 Agenda – Czwartek, 25 czerwca
18:00 – Check-in i networking
18:15 – Powitanie, otwarcie i wprowadzenie do laboratorium
18:30 – Warsztat (BRK231/LAB520) – Część 1: Deploy & Observe
Rozpoczynamy pracę z platformą Microsoft Foundry. Zobaczysz, jak zespoły programistyczne konfigurują i monitorują agentów AI na produkcji, zbierając realne sygnały o ich działaniu.
19:30 – Przerwa na pizzę 🍕 i networking
20:00 – Warsztat (BRK231/LAB520) – Część 2: Learn (Reinforcement Learning & Fine-tuning)
Przechodzimy do zaawansowanej optymalizacji. Przeanalizujemy, kiedy fine-tuning redukuje koszty i opóźnienia (latency), a kiedy uczenie ze wzmocnieniem (RL) przynosi najgłębsze zyski dla systemu.
21:00 – Podsumowanie, Q&A oraz kolejne kroki
***
### 🛠️ O warsztacie (BRK231/LAB520)
Deploy. Observe. Learn. Reinforcement learning for production agents Przejdziemy wspólnie przez ścieżkę optymalizacji systemów agentowych, opierając się na architekturze Microsoft Foundry. Dowiesz się, jak bezpiecznie trenować, oceniać i wdrażać agentów, a także posłuchasz o realnej drodze od eksperymentów z RL do systemów produkcyjnych (m.in. na przykładzie case study od Johnson & Johnson).
***
### ✅ Wymagania przed wydarzeniem
Warsztat jest prowadzony na poziomie średniozaawansowanym (Intermediate). Aby wyciągnąć z niego 100% korzyści, upewnij się, że masz ze sobą:
💻 Własny laptop (Windows / macOS / Linux) wraz z zasilaczem.

Customize the IDE: Building Extensions for Visual Studio Code - Alan Barber
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
*Customize the IDE: Building Extensions for Visual Studio Code*
Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs.
In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling.
The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options.

AI Agents 101: How to Make ChatGPT Do Actual Work
Most people still use AI like a search box: type one question, get one answer, repeat.
But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review.
In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity.
We’ll cover:
* What makes an AI “agent” instead of just a chatbot
* How agents break tasks into steps
* Where agents are genuinely useful today
* Where they fail, hallucinate, or need human review
* How to design simple AI workflows for your own work
* A live demo of an AI agent-style workflow from start to finish
No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
