**PLEASE ALWAYS CHECK THEIR REPECTIVE WEBSITES! Sometimes they cancel events and you don't want to go there for nothing.** This Contact Jam happens every wednesday. Entry is 5€ i think. It is hard to find. You have to go into the last courtyard (it's pretty dark). And then the staircase into the 3rd floor. The room is pretty small and gets crowded easily, take care of yourself while dancing. Please check out their link. http://k77studio.org/timetable/event/contact-impro-jam-20-30-20-50h-warm-up-with-berlin-ci-teachers/

## Hispanic Startups Berlin is back — and we’re joining forces with Nova After a long pause, **Hispanic Startups Berlin is back** with a new afterwork meetup — and this time we’re doing it together with **Nova**, the global community for high-performing professionals. For this May edition, we’ll meet at **BrewDog Mitte** for a relaxed evening of drinks, conversations, and new connections with people from the Hispanic startup, tech, business, and innovation ecosystem in Berlin. Whether you’re a founder, marketer, operator, product person, investor, freelancer, student, or simply curious about the startup scene, this is a great opportunity to reconnect with the community and meet new people in an informal setting. We’ll keep it simple: good drinks, good conversations, and a room full of interesting people. **Date:** 20/05 **Location:** BrewDog Mitte **Format:** Informal afterwork drinks **In collaboration with:** Nova Come join us, bring a friend, and help us bring Hispanic Startups Berlin back to life.

**We’re back!** After a break, the Berlin Tech Leads meetup is officially revived **\- and this time IRL at Berlin Vinted office\.** **We’ve missed the deep dives, the architectural debates, and the networking. To kick things off, we’re tackling one of the fastest-moving landscapes in the industry right now: the intersection of Engineering and Customer Support.** **About the Event** Customer Support is often the first place where AI moves from "experimental" to "mission-critical." For Tech Leads, this shift isn't just about plugging in a basic chatbot; it’s about re-engineering the entire lifecycle of a ticket and how our systems actually interact with our users. In this meetup, we’re looking under the hood of the support stack. We’ll discuss how the landscape is being reshaped by LLMs, the shift toward autonomous agents, and the real technical hurdles of building multi-modal support systems. **Talks:** * [Pau Agustín](https://www.linkedin.com/in/pau-agust%C3%ADn-granell-6420a5139/) & Team Help Experience (vinted.com): "Scaling Support: How Vinted Manages Tens of Thousands of Tickets Every Day" * [Yam Marcovitz](https://www.linkedin.com/in/ACoAAAbVVAwBOgouy-uT1QB1ixhqrafAv1kNxQk) (parlant.io) "Building consistently aligned agents with Parlant" * [Richard Lohwasser](https://www.linkedin.com/in/ACoAABRCCmYBD9PS9O73AjQ244LC4Gc_NMUcnsY) (enneo.ai): "Applying AI across all channels in real-life customer service at scale: What works, what doesn't, and where we're heading to?" *Just a quick reminder: if you'd like to take the stage and speak at a future Berlin Tech Leads meetup, feel free to drop a message to one of the organisers.*

In May, [Bruno Caballero](https://github.com/bruno-ah-um) will show us how to target hardware accelerators from Java with MLIR based on [his fork of the OpenJDK Project Babylon](https://github.com/bruno-ah-um/openjdk-babylon-mlir-tosa). Bruno leads the Java Virtual Machines Engineering team at [MicroDoc](http://www.microdoc.com), which develops JVMs and maintains ports across various processors and operating systems. In this talk, we’ll explore a toy project that translates Java code into MLIR for the TOSA dialect, which is used for AI and accelerator workloads. We’ll briefly introduce current approaches (e.g., TornadoVM and Babylon/HAT), before looking at how this project reuses existing compiler infrastructure instead of building new backends. Finally, we’ll touch on whether DSLs should be embedded in general-purpose languages like Java or designed as standalone languages. Small snacks and drinks will be available. There is always space for outside topics and discussions. If you have specific questions, please bring them. Looking forward to meeting everyone again!

The course will start this Saturday at 10am. It will be in studio R at CCB studios. [https://maps.app.goo.gl/rFovxE7eG7HV6uB46](https://maps.app.goo.gl/rFovxE7eG7HV6uB46). Buzz for CCB studios and then walk through to the second courtyard. We will try to start right around 10. There will be tea available. Please dress in comfortable clothes, maybe wearing a few layers. Theres some blankets, yoga mats, cushions and chairs in the room that you can use. The plan will be for us to do some small discussions at the top and then start discussing theory before doing some meditations of increasing length and then closing with some time for Q & A. We will take a short break in the middle as well. The plan is to go from 10-12 roughly but we may end a little closer to 11:30 depending. This week will function primarily as a simple introduction to meditation and some topics in the space but we will also discuss what the Jhanas are. Looking forward! Any questions please just message me.

\#\#\# Was ist Breathwork? Conscious Breathwork bedeutet bewusstes atmen. Und das ist es letztendlich auch, was wir etwa 70 Minuten lang machen werden. In einer Breathwork Session geht es vor allem darum, dass Du loslassen, Dich entspannen und mit Dir selbst und Deinem Unterbewusstsein verbinden kannst. Das geht am besten, in dem Du gar nichts erwartest und nicht so viel dadrüber nachdenkst. ✨ \#\#\# Das erwartet Dich Nach einem kurzen Check-In beginnen wir mit der Session. Die Atmung kann im Liegen oder Sitzen statt finden, ganz nach Deiner Wahl. Du wirst durch ein bewegendes Musikset geführt, wodurch Du in eine Trance-Atemmeditation gelangst. Hier kannst Du unter anderem diese Erfahrungen machen: Stress abbauen, herausfinden, was da noch in Dir steckt, Dein Potential entfalten, innere Anspannungen lösen oder unterdrückte Emotionen freilassen, in Dich hinein horchen und Lösungen finden, Kreative Ideen und Visionen erhalten oder einfach eine berührende Zeit haben. \#\#\# Über Nina Seit 2015 bin ich [Anusara® Elements™](https://www.anusarayoga.com/) Yogalehrerin. Es folgten viele Weiterbildungen in den Bereichen Chakren, Meditation, Yoga und Trauma. 2018 habe ich mich zudem auf die Heldenreise begeben. Seit 2023 bin ich Atemtherapeutin Conscious Breathwork nach der [Lichtatmung®](https://naou.de/lichtatmung/) und freue mich sehr, Dich bei Deiner Reise begleiten zu dürfen. In meine Sessions fließen meine unterschiedlichen Erfahrungen ein. Was mich jedoch am meisten bewegt: Mich begeistert alles, was Dich mehr bei Dir selbst ankommen lässt, Dich mit Deiner Lebendigkeit und vor allem Deinem Herzen verbindet! \#\#\# Bitte mitbringen: – Yogamatte oder andere Unterlage (z.B Isomatte), damit Du es schön gemütlich hast – Lockere, angenehme Kleidung – Alles andere, was Dich noch wohlfühlen lässt. Decken, Wasser und Snacks gibt es vor Ort! \#\#\# Deine Investition & Buchung Der Standard Preis beträgt 25 €. Das Ticket 1+1 Bring a Friend kostet 45€ und ist gültig für zwei. Du kannst die Tickets hier kaufen und mit mit allen gängigen Zahlungsmethoden schnell & einfach bezahlen.

Join us this Friday at Treptower Park for a cozy evening of board games and connection! The mission of Quarter Life Connections is to create spaces for **young people in their twenties** to connect and feel at home in Berlin - especially once the familiar structures of university life stop being there and work life starts. We will start with a quick get-to-know-you round and then split up into smaller groups for games. After up to 2 hours of playing we will close with a check-out-and-stay-in-touch round. The intention is to have fun while getting to know the people around you and form start building connections that will last after the event is over. **Please be on time!** The intro circle sets the tone for the event and is a huge support for making meaningful connections. BRING YOUR OWN GAME - and stuff We will have enough games there to entertain everyone - but maybe you have a game at home you think would be fun to play together? Bring it! Also any addition of **picnic blankets** or **snacks** are very appreciated :) CONTRIBUTION In order to make events like this sustainable, we ask for a voluntary donation - suggestion is between 2€ and 10€. This really is **voluntary** \- noone will be turned away due to lack of money\.

Come along, grab a coffee, shut up, and write! We will do at least two sessions of each 45 minutes of writing and two breaks. We will start the first writing session at 10:45.

In the summer, also outside. Looking forward to seeing you there!

Come along, grab a coffee, shut up, and write! We will do at least two sessions of each 45 minutes of writing and two breaks. We will start the first writing session at 11:15. **For space reasons, we are limited to a certain number of attendees, so please update your RSVP if you can't come**. We often have a large waiting list, and not updating your RSVP or not showing up if you do RSVP yes means that others miss out. We also ask that if you do change your RSVP, do it with reasonable notice. Thanks! We typically take over all of the cafe, but try to share tables if you can to allow space for other customers. If you are new, come and say hello, as we know that suddenly going quiet for 45 minutes and staring at that blank page can be intimidating when it's your first time. We have a lot of long-term regulars who will be happy to help you feel welcome.
