Transactional Saga Pattern
**Liebe Gophers,**
am 13.Mai geht es bei uns um eines der wichtigsten Patterns in verteilten Systemen: das **Transactional Saga Pattern**.
Wer mit Microservices arbeitet, kennt das Problem – eine Bestellung aufgeben klingt einfach, aber dahinter stecken Payment Service, Inventory Service, Shipping Service... und jeder hat seine eigene Datenbank. Was passiert, wenn mittendrin etwas schiefläuft?
Klassische ACID-Transaktionen funktionieren hier nicht. Sagas schon.
Unser Speaker Mark Borukhov zeigt, wie das Saga Pattern funktioniert – mit echtem Go-Code, einem E-Commerce-Beispiel und Live-Demo.
**Was euch erwartet:**
* Warum verteilte Transaktionen ein echtes Problem sind
* Saga Pattern: Konzept, Choreography vs. Orchestration
* Implementierung in Go – Schritt für Schritt
* Pitfalls, Lessons Learned & Q&A
Das Event richtet sich an alle – von Go-Einsteigern bis zu erfahrenen Entwicklern. Auch wer Go nicht kennt, aber Microservices baut oder Patterns liebt, ist herzlich willkommen.
**Der Vortrag wird auf Deutsch gehalten.**
Wir treffen uns um 18 Uhr bei [lynqtech](https://www.lynq.tech/). Mit dem Vortrag starten wir um 18:30 Uhr. Danach wollen wir über Technologien und Erfahrungen plaudern, voneinander lernen, Kontakte knüpfen und einfach eine tolle Zeit miteinander verbringen.
Wir freuen uns auf euch! 🚀 *Mark & Anna*

From Overwhelm to Ease - an EFT Tapping Workshop
From Overwhelm to Ease - an EFT Tapping Workshop
By Roshanak Zaredoost
Brussels, 13 May 2026
Rgeister Here: https://www.imaginationclub.org/brussels/from_overwhelm_to_ease.php
Living abroad is an adventure - and also quietly exhausting. New country, new language, new identity. Your nervous system is working overtime, even when life looks good on the outside. In this hands-on workshop, you'll discover Emotional Freedom Techniques (EFT tapping): a gentle, evidence-based tool that combines acupressure and mindset work to help you release stress, calm anxiety, and reconnect with yourself - wherever in the world you are.
What you'll take away:
\* A practical tapping routine you can use anytime, anywhere - in 5 minutes or less - to bring your nervous system back to calm.
\* A deeper understanding of the stress cycle - why your body reacts the way it does, and how to interrupt it with compassion rather than willpower.
\* Personalised tapping phrases that speak to your specific challenges - loneliness, identity, overwhelm, not fitting in - so the tool actually feels like yours.
\* A sense of being seen and understood - in a room full of people who get it, because they're living it too.
No experience needed - just bring yourself, exactly as you are. You'll leave with a tool for life and a little more peace in your body.
Join us for From "Overwhelm to Ease" and take the first step toward a calmer, freer, more authentic you.
About Roshanak
Born in Iran and living abroad for over 41 years, she has spent a lifetime navigating the beautiful complexity of building a life far from home. That journey - with all its richness, displacement, and reinvention - is at the heart of everything she does as an EFT coach.
Her path to EFT was forged through her own transformation. She has walked through financial dependency, emotional dependency, abusive relationships, overeating, and the quiet suffering of a woman who had lost her voice - and come out the other side. Not by chance, but through deep, committed inner work. EFT was the tool that helped her break free from limiting beliefs one by one, and she has never stopped using it on herself. That ongoing personal practice is the foundation of everything she brings to her clients.
Today, as an EFT coach whose practice is rooted in lived experience, she specialises in guiding women abroad through stress, anxiety, and overwhelm - helping them calm their nervous system, shed what no longer serves them, and step into a life of authenticity and self-love.
Fluent in 6 languages and passionate about human connection, she meets every woman exactly where she is - with compassion, understanding, and the quiet confidence of someone who has been there.
Her greatest joy is watching her clients step into their own freedom - emotionally balanced, self-aware, and unapologetically themselves.

Intervals Workout Session 🏃🏻♂️🏃🏼♀️🏃🏻 Hippodrome de Boitsfort
We do cycles of 4-6 weeks, with a progressive intensity, and the last session is lighter.
Program:
15’ warm up
**To be defined**
Cool down to get back to the starting point… or more
S=All out sprint
RF = Run fast, at MAS (Maximum aerobic speed)
CF = Run comfortably fast (1h threshold)
J = Jog, recuperation
Notes:
It should take about one hour in total, as the cool down will end when we reach back to the meeting point.
It's NOT required to have an activity tracker or smart watch to be able to follow the program, as I'll be giving signals with a whistle.
For the "run" part, you can follow your own pace and we'll be regrouping in the "jog" part.
Intervals training is not advised for total beginners. To have an idea, the average pace at the warm up is around 5'45"/km-6'/km so this pace should feel very comfortable
***Acknowledgement of member responsibility and release of liability.***
By signing up for this event, you agree to release the organizers from any responsibility and liability in all claims. As the participation is strictly voluntary and you freely choose to join, it is the responsibility of individuals participating to ensure that they are fit enough and have adequate coverage to protect themselves.
Queer Reads Collective: Boyfriend Material by Alexis Hall
Hey lovely people,
Join us for another gathering of the **Queer Reads Collective**. Since we have been reading some quite heavy books lately, we decided to do a round of something lighter for the spring. Our May read will be *Boyfriend Material*
by Alexis Hall.
When tangentially ― and reluctantly ― famous Luc O'Donnell is forced back into the spotlight in the worst possible way, he has to think fast if he wants to save his floundering reputation. Enter Oliver Blackwood. Stunningly handsome and effortlessly put together, Oliver is successful, an ethical vegetarian, and has never appeared in a scandal mag evenonce. In other words, he's perfect boyfriend material and exactly what Luc needs to appear respectable again. But when their fake relationship starts to feel like real romance, Luc and Oliver might have to consider whether they're willing to fight for the truth of their new relationship…scandal, and consequences, be damned.

UNO #474
Let's continue the tradition and play UNO, everybody is welcome :)
If you're on the waitlist please check your messages, especially on Sunday. If people drop off last minute I tend to message people on the waitlist to see who can come.
We'll be playing at the lobby of Radisson RED, Brussels. The address of the hotel is:
Rue d'Idalie 35, 1050 Bruxelles
My number is 0471 45 55 02. Feel free to call if you cannot solve a physics question, cannot find the place or simply need a hug.
I have quickly written a set of rules on how we play. It is assumed that the reader has a basic concept of the game.
***
Setup:
* Each player starts with 6 or 7 cards each (depending on total number of players)
* A card is shown in play in the middle of everyone, this is known as the top card.
Goal:
* The goal of the game for each player is to get rid of all cards in your hand
Rules:
* Whenever you go from two cards to one card, you have to say "UNO".
* Each player takes his turn one by one, initially going in the clock-wise direction
* A card may be played if it matches the same colour or same number or same type as the top card in play
* The two black cards (Draw 4 and Wild) can be played regardless of the top card in play.
* Interruption rule: You may interrupt the general flow of the game (clockwise or counter-clockwise) if you have the EXACT same card as the top card in play. If you manage to play the card prior to the person whose turn it's supposed to be, then the game continues on from you in the same direction it was previously. (Unless the reverse card was interrupted, then the direction changes).
* Draw2 or Draw4 cards can be played in accordance to the interruption rule. The following person after the interrupt has to take the accumulated number of cards. If however, cards have already been drawn AND seen by the person who was supposed to take the cards, then only the remainder of cards has to be drawn.
* Once someone has no cards remaining in his hand, play stops and we start counting points.
Points:
* Number cards have the face value as the number of points. i.e. number 6 is worth 6 points, number 0 is worth 0 points, number 4 is worth 4 points.
* Skip, reverse and Draw2 are worth 20 points each
* Wild and draw4 are worth 50 points each

How to Take Control of YOUR Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind.
Find out what the reactive mind is, and in the process find yourself.
Here is the secret of being positive and free:
Thinking positively is not enough.
You also have to get rid of the negative thinking.
Your mind is like a garden.
You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden.
A positive thought is like a flower in your mental garden, and a negative thought is like a weed.
You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there.
So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out!
The Meetup event will be led by a consultant who had helped many people live happier in 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 & Scientology life improvement center.
The Non-competitive Tennis Partner Program
We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level. This program is less competitive, no champions crowned, no league standings just dedicated tennis partners who want to meet up with you on the courts. Players will meet up to play a tennis match or just to hit around. Just go through the [Join Page](https://www.tenniscolumbus.com/partner-program) to enter this program.

LLM Showdown: ChatGPT vs Claude vs Gemini vs Local Models
Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability.
You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required.
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.
Columbus Code & Coffee 86 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
**What to Expect at the Intro Circle**
\~\~\~\~\~\~\~\~\~\~\~\~\~
Near the beginning of the event (1:30 pm), we do a standup:
* Organizer announcements, updates, and logistics
Round 1 - (7 secs max):
* Your name
* What you're working on
* What you can help others with
Round 2:
* Community events you wanna plug. If none, that's cool too.
Round 3:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
