Dream Team Group Experiment
In this experimental Success Team we'll work on each-other's earthly goals–even, embarking on seemingly unachievable dreams...
\*\*\*
Help wanted & help offered. Bi-weekly meetings (every two weeks). Language English/Dutch.
This idea is inspired by Barbara Sher's story and experiences. Please see her Ted Talk titled "Isolation is the dream-killer, not your attitude".
The idea in short: One person at a time tells the group his/her dream or aim and the obstacles they face to achieve it.
It could be a trip, an experience, a change of career, an undertaking of some kind, learning a skill, solving a particular problem or even finding out what you really want.
The group works to realise the person's aim. Not just theoretically, also practically. For this we use our experience and networks.
—Nothing as satisfying as helping another! Perhaps suitable, Gabor Mate's words: "You never heal alone."
Please contact me at galatv@protonmail.com if you have questions.
We gather in a pleasant space at Rosa Buurtcentrum. On the 2nd floor ("eerste verdieping"), take the door at your right (right from the staircase), at end of the small hall, the last door left). There will be tea and you are welcome (but not required) to bring snacks. It's free (50 cents for tea contribution is appreciated). We'd love to have you.

[Arnhem] English subs: Romería
#This meetup is around a third-party organizer (Focus Filmtheater): you can either purchase your ticket online or right before the session. **Seats are numbered**#
**Title**: Romería
**Language**: Spanish
**Subtitles**: English
**Length**: 112 min
**Director**: Carla Simón
**More info**: https://www.focusarnhem.nl/agenda/english-subs-romeria/
**Ticket link**: https://www.focusarnhem.nl/tickets/143040/
**Synopsis**:
Marina loses her parents to addiction and illness at a young age. When she’s older, the aspiring filmmaker sets out in the summer to find her roots in the northwestern coastal region of Spain, she finds herself caught in a web of conflicting memories and heartbreaking discoveries. The award-winning Spanish filmmaker Carla Simón based this wistful, sun-drenched portrait on her own experiences.
Does a shared bloodline automatically make you family? Marina was orphaned at a young age. When she turns 18, she travels to sunny Vigo, camcorder in hand. In this Spanish city on the Atlantic coast, she will finally meet her father’s family, whose signature she needs for a scholarship application.
There, she encounters a whole host of uncles, aunts, cousins, and grandparents. The family is warm and welcoming, yet also irritable and evasive, wealthy and distant. As Marina pieces together the puzzle and tries to form an image of her parents, she is confronted with conflicting memories and heartbreaking new information. In 2022, Carla Simón received the Golden Bear in Berlin for Alcarràs. With Romería (“pilgrimage”), she shares an intimate piece of autobiographical fiction that poignantly reveals how we can never fully know our parents. Both Llúcia Garcia and the breathtaking Galician coastline deliver stunning leading performances in this film, which shows that filmmaking — and storytelling in general — is a powerful way to come to terms with an elusive past.
**How it works**:
I will be at Focus around 18:30, where we can meet before the movie starts. You can message me to find us. Screening starts at 19:00. After the movie, we can have a drink together.
Hope to see you soon!

Hamburg PowerShell User Group #43 - Publish-Blog - PowerShell for the static age

Das Treffen findet vor Ort (bei glueckkanja) und online statt. Link nach Anmeldung in meetup einsehbar.
1\. Welcome
2. **Publish-Blog - PowerShell for the static age**
Creating content for a blog can be challenging — running the blog itself absolutely is not! Especially when PowerShell comes into play.
**Andi Bellstedt** unveils the mechanisms behind his new blog. He demonstrates how GitHub Actions and CI/CD pipelines work together to build, test and publish a static website the PowerShell way.
Get practical ideas to simplify and solidify your workflows for static site creation. Along the way, there will be demos showing how AI supports parts of the development process and how these tools help maintain the blog efficiently.
3\. Q&A
Wir freuen uns auf eure Teilnahme.

What If Your AI Could Be a Team? - Chad Green
**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**
GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise.
We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration.
Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team.

Fun & easy way to play more tennis (read event description)
We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches.
These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun!
Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up:
https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/
If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works.
Happy hitting!

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!
Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machine’s?
This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
We encourage audience participation during this event that will be moderated by Chris Slee.
Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
