Bike Commuting Berlin

Bike ride + Spa #1 (Königs Wusterhausen → SATAMA Sauna Resort and Spa)

# Königs Wusterhausen → SATAMA Route: Königs Wusterhausen → Bestensee → Storkow → Wendisch Rietz Distance: 38 km, mostly flat (70m elevation total) Mixed terrain. About 23 km asphalt, the rest gravel paths and forest tracks. Meeting point: Berlin Ostkreuz, RE7 direction Senftenberg, departure 09:02 Back in Berlin: \~21-22:00 We meet at Ostkreuz, take the RE7 to Königs Wusterhausen and start the ride from there. If the RE gets cancelled, then we will use S-Bahn with a connection in Grunau. The first section heads south through the Dahme-Seenland lake district. Flat terrain, a mix of bike paths and quiet forest/countryside roads. Near Bestensee, we pass the Großer Tonteich. If the weather holds, we can stop and swim. It's a small lake, not well-known, the kind of place you wouldn't find unless you were riding past it. From there, the route continues through pine forest and along the edge of farmland. In Storkow, we will stop for a lunch and to see the castle. We arrive at SATAMA on Scharmützelsee in the afternoon. The sauna park sits directly on the lake. In my opinion, it's one of the cosiest saunaparks in Brandenburg. Nine saunas, outdoor terraces, a pool, hammocks, and the direct access to the lake! We'll be there for several hours. At around 20-21 pm we board the RB36 train in Wendisch Rietz and change for RE7 in Königs Wusterhausen. Plan for arriving back in Berlin around 21-22:00. **Tickets** If you have the Deutschland-Ticket, you're fine and will only need the 24-hour bike ticker for VBB. Otherwise you'll need one Berlin ABC ticket, one VBB Gesamtnetz ticket and a 24-hour bicycle add-on for the VBB network (\~€7.50) **Bike** Trekking bikes and city bikes with wide tyres work. Road bikes, fixies, and rental bikes don't. **What to bring** * Water and snacks * Sauna towels, bathrobe, slippers (you can also rent it on-site) * Lights (front and rear, charged the night before) * Spare tube **SATAMA** Saunapark Entry is around €50 on weekends. It's a popular place, so book your ticket in advance at [satama-saunapark.de](https://www.satama-saunapark.de/). Each person books and pays individually. SATAMA is FKK. If that doesn't work for you, this isn't the right event.

After-work bike ride: Südkreuz → Griebnitzsee (~25 km, one way)

After-work bike ride from Südkreuz to Griebnitzsee - one way, S-Bahn back. Shake off the workday with a relaxed evening ride out of the city. We'll follow the Teltowkanal southwest, ride through the quiet paths of Düppeler Forest, and arrive at Griebnitzsee - a beautiful lake on the Berlin-Potsdam border with a historic lakeside promenade lined with old villas. Depending on timing we'll stop for a drink at the lake before catching the S-Bahn back together. The train ride back is a good chance to chat and wind down. Any bike type works. No special experience needed - just show up and enjoy the ride. • Start: S-Bahn Südkreuz • End: Griebnitzsee S-Bahn station (S7 back to Berlin) • Distance: \~25 km (one way) • Terrain: Flat to gently rolling, canal paths and forest tracks • Pace: The one you're comfortable with - we're here to relax after work, not to race • Recommended to bring: water, lights, S-Bahn ticket or BVG app for the return • Equipment: Up to you but you're responsible for your own safety. Food and drinks at the stop not included - pay your own. See you! 🚲

Cycle & dine - Rathenow to Brandenburg

**ATTENTION - This tour is postponed now to the 4 July due to the heat to be expected this Sat.** **But everything else stays the same.** ========== FACTS ========== ROUTE: Rathenow > Milow > Kirchmöser > Brandenburg/H LEVEL: Intermediate DISTANCE: 45ish kms MEETING POINT: 09:20 - Berlin Südkreuz ========== FACTS ========== ========= DETAILS ========= **ROUTE:** Starting in Rathenow we have a very flat tour ahead of us. The first stop is planned after some 10km at the [GastHof Milow](https://gasthof-milow.com/) which is known for serving very delicious fish. Just in case there might not be enough seats available we will head further to Plaue, passing the Plauer See and then have plenty of other opportunities to sit down, look across the water and enjoy some food and a drink… or two. The final route depends on mood and weather! After \~45km we will arrive the main train station in Brandenburg/H where we can hop into any RE1 coming. **SPEED:** Leisurely around 14 km/h, at least if the wind doesn't come from the front. This is like "Being able to see the details on the side of the road and enjoying the view in general… and have a chat." **DISTANCE AND TERRAIN:** This is an about 45ish km ride, with mainly solid but also some soft ground. In general: Bikes with thin tyres (Race bikes, Road bikes, Fixies), rented bikes (Uber, Swapfiets) or any special bikes (Folding bikes, BMX etc.) are not suitable! You won't have fun, trust me! And if you want to bring Kids or Animals please get in touch before! **MEETING POINT:** 09:20 - Berlin Südkreuz, at the NORTHERN ticket machine (facing the TV tower) on platform 6. I have a blue Villiger Trekking bike. But you can hop in at any other station if you want (and dare). **TICKET:** It is 23,60 both ways / person, so this time it does make much sense to organise a BBT. I will get one if at least one other person wants to join me! And don't forget your "[24-hour ticket bicycle VBB network](https://www.vbb.de/en/tickets/tickets-for-your-bicycle/24-hour-ticket-bicycle/)" ticket which is about 7,50 EUR. **WAY OUT:** 09:44 - dep. Berlin Südkreuz, platform 6, taking RE4 to Stendal Hbf 10:04 - arr. Rathenow, platform 1 **WAY BACK:** 17:04 - dep. Brandenburg/H, platform 3, RE1 to Frankfurt/Oder 17:38 - arr. Berlin Wannsee, (ME) switching trains to S2 18:01 - arr. Berlin Friedrichstrasse OR any other train at :04 or :44 **RECOMMENDATIONS:** Check the train schedule in the morning! The DB loves to stir up the plans by changing trains on short notice! If anything happens the Meeting point is the starting point of the cycling. While we'll stop somewhere for a lunch and/or coffee please always bring your snacks but especially some drinks along! And, PLEASE make sure your bike is in a proper state! Check your tyre pressure and oil the chain! Does your light work? Having a toolset is highly recommended and a spare inner tube to fix a flat tyre a big plus! While we might be able to help in some circumstances please think about what happens if we can't! Thank you! Bringing special equipment (Helmet, safety vest etc.) is NOT required but welcome if you feel more safe using it. And in case you need special medical treatment please make me aware of that upfront. Even if everyone is responsible for themselves I'd like to be able to handle it if necessary. ========= DETAILS =========

Hike from Lübben (Spreewald) to Schlepzig

Join us for our second hike of the summer! We will start by meeting at (or at least boarding) the **10.40 RE2 (3112)** at **Ostkreuz** station, **Platform 1**. We will arrive at Lübben (Spreewald) at 11.25. *Note that if you miss this train, then the next one does not arrive until 11.56, so you will certainly miss us and won't be able to catch up!* The hike will go from Lübben to Schlepzig, along the canals and lakes of the beautiful Spreewald region. *(See photos for a rough route -- this is not necessarily accurate!)* The walk will be about 15 km and take about 4-5 hours. Bring lunch, snacks & water, comfortable walking shoes, and maybe even some sunglasses. We will stop a couple of places along the way, but will not stop long enough to order food, so bring your lunch! At the end of the walk, in Schlepzig, there is a Whisky brewery and a Biergarten. We will visit one or both. You can also get food at both. Then, we will take the 18:57 bus back to the starting point of Lübben Bahnhof. From there, we will catch the 19.34 RE2 (3129) back to Ostkreuz, arriving at 20.23. *(If you really want to, and if we get to Schlepzig in time, then you can also take the 16.52 bus to Lübben, then the 17.34 RE2 back to Berlin.)* **Note: We will reschedule this if the weather is too rainy. So definitely check back here before going!**

Agentic AI in the Wild: What Actually Runs in Production

Register: [https://globalai.community/e/7lns53g4](https://globalai.community/e/7lns53g4) ## Connected Intelligence: AI Builders Meetup — WeAreDevelopers PreDay, Berlin AI agents are moving into production. The question is no longer whether to use them, but what it actually takes to make them work once the demo is over. This WeAreDevelopers PreDay meetup is for builders, founders, and practitioners wiring AI agents into real codebases, CI/CD pipelines, developer platforms, and knowledge systems. The evening focuses on the honest conversations that rarely fit into a conference talk: what breaks at scale, what context engineering really looks like, and where the failure modes hide. The theme is **connected intelligence**: how graph-based reasoning, smarter pipelines, and agentic code review are changing production AI systems, and what engineering teams need to do differently to support them. We will explore constraint satisfaction in agent decision-making, agentic AI in production, AI-powered development workflows, and Java’s role in the future of AI systems. No vendor pitches. Just the stuff that runs in production.

Lessons from the Field: Scale, Availability, and Performance

**[IMPORTANT NOTICE registration is HERE](https://luma.com/wh28yfqv)** ​**Please bring a valid ID (driving licence or passport) with you on the day, as it will be required for entry to the venue.** Join **Aerospike** **AWS, Adjust and Miro** for an evening of technical talks focused on the challenges of running real-time, business-critical systems at scale. Hear firsthand lessons from engineers managing large datasets, database migrations, and cloud infrastructure availability in production. From Miro's Redis-to-Aerospike migration on Kubernetes to AWS best practices for capacity planning and resilience, speakers will share practical insights gained from operating demanding workloads where performance and reliability matter. ​Connect with fellow engineers, architects, and technology leaders from Berlin's tech community over drinks and networking. ​ ​**Agenda** **17:30 – 18:00 - Welcome & networking** **18:00-18:10 - Speed vs Capacity: Designing Data Systems for Real-Time Scale** *Dirk Möller, Regional Lead Germany and EE, Aerospike* In high-performance data systems, balancing RAM and disk is key to real-time performance at scale. This session explores the technical nuances of database architecture in today’s AI-driven era, where workloads demand low latency, massive scale, and adaptive infrastructure. Drawing on real-world, mission-critical systems, we’ll show how to achieve the right mix of speed, scale, cost-efficiency, and reliability - designing architectures that meet today’s real-time demands while staying sustainable and affordable. **18:10 – 18:30 - Scaling Beyond Millions of Transactions** *​Leonardo Muñoz, Platform Engineer, Adjust* A behind-the-scenes look at how Adjust powers high-throughput, low-latency workloads at scale using a distributed database platform running on bare metal infrastructure. Leonardo will explore the architectural and operational decisions behind the deployment, the challenges of managing dedicated hardware at scale, and the lessons learned from years of production experience supporting mission-critical workloads. **18:30 – 18:50 - Pod Ready ≠ Data Safe: Migrating a Critical Dataset on Kubernetes** *Yuriy Chernikov, Staff Software Engineer, Miro* ​ Miro migrated one of its most critical datasets from a legacy caching platform to a modern distributed database running on Kubernetes - and not everything went according to plan. This practical talk covers what the migration actually required, the design decisions that made failures survivable, and the operational lessons that only emerge when managing datasets measured in terabytes. **18:50-19:10 - Managing Amazon EC2 Capacity and Availability** *Nati Cohen, Sr. Specialist Solutions Architect, Compute, AWS* ​ Modern data-intensive applications require infrastructure that delivers high performance, scalability, and resilience. Organizations often seek to leverage the latest storage-optimized EC2 instances, select larger instance sizes for improved performance, place infrastructure close to data producers and consumers, and scale efficiently as business demands grow. In this session, we'll explore how to balance these performance requirements with cost optimization and capacity availability. We'll review the various EC2 capacity and reservation models, including Capacity Reservations, On-Demand Instances, Savings Plans, and more. Learn how to combine these options to optimize cost, performance, and availability for large-scale production workloads **19:00-20:00- Networking** **[IMPORTANT NOTICE registration is HERE](https://luma.com/wh28yfqv)**

Afternoon Walk+Coffee in Berlin: Alexanderplatz to Zoologischer 👣🚶🚶‍♀️☀️🥐☕🍪

1 EURO DONATION FEE PER PERSON IS REQUIRED (on site, in cash), to pay back the Meetup subscription fees and support my Events. READ THE DESCRIPTION WITH THE INFO (IMPORTANT). We take a walk in Berlin to meet new people or people we already know 😁 It's a way to spend a few hours together on a Sunday afternoon. **How it works?** The concept is very simple: * We meet at Alexanderplatz Station at 14,00 o'clock (we use the Whatsapp Chat to find each other: I will post there my exact location in the station) * I wait for people for 10 minutes, till 14,10, then we start to walk direction West, crossing Museum Island and Mitte 🏛️🏘️ * We reach Tiergarten and we will cross the entire park, seeing some of its interesting points🌲🌳☘️ * We finally reach Café am Neuen See: https://maps.app.goo.gl/kSui84icxyU6hQG56 to sit down together to take something to drink or eat 🥐☕🍪 * The total length of the walk is about 8kms I consider that the event will last in overall around 4 hours (2 hours of walk and 2 hours at Café am Neuen See), but people are free to stay together longer, if they want 🙂 What I provide is leading the walk and the people at Café am Neuen See, but I do not force anyone to stay shorter or longer. I do not provide a "personal support" for people who arrive after 14,10 (do not write to me expecting "private support"). You are responsible to check for the weather and decide if come or not.

Ascent of Mount Brocken ⛰️🌳From Berlin 🚆

2 EURO DONATION FEE PER PERSON IS REQUIRED (on site, in cash), to pay back the Meetup subscription fees and support my Events. READ THE DESCRIPTION WITH THE INFO (IMPORTANT). WHATSAPP LINK BELOW 📳​ We take the HBX train that departs from Berlin Gesundbrunnen at 07,02 AM and arrives to Ilsenburg at 10,29 🚉😀 The train is available also in Lichtenberg, Wannsee and Potsdam. I attach the screenshot with all the stations. The train is Deutschland Ticket valid. Once in Ilsenburg station, we take a local bus to save a bit of walking (since the actual Hike will be already very long 😆💯). I attach the screenshot of this bus connection, here the website of the local buses (note: these connections are not present on Google Maps) 🚏: https://www.insa.de/ We then start our Hike and this is the path 🚶‍♀️🚶 The Brocken Mountain is the highest peak in northern Germany ⛰️ with an elevation of 1,142 meters https://www.komoot.com/tour/2936906879 Bring your own food 🍔 and drinks 🥤, we will take breaks where we deem appropriate. IMPORTANT: please consider that the Hike is 24kms with 860 meters of elevation difference, come only if you know that you are physically fit 😊 People who do not want/can make the whole Hike can join and decide to come back earlier without making the whole route 😊 NFO ℹ️ℹ️ Route distance: 24 kms Elevation difference: 860 meters up and 860 meters down (it is a loop) Breaks ⛔: When and where we deem appropriate. On the way back it seems there are no local buses, in the late afternoon, from Parkplatz Ilsenburg Brockenwanderung to the station, so maybe we should walk 2 kms more. A direct train to come back from Ilsenburg to Berlin is available at 17,31 (HBX), but maybe (or even probably) it will be too early for us. Other connections are anyway available, changing train in Magdeburg 🚉 If you have to contact me, make it via Whatsapp, not here on Meetup.
