Come join us on playing the small astro outdoor pitch with walls and goals at Jahn-Sportpark. Like inside Hallenfußball - but outside! We play 4vs4 or 5vs5 with up to 2 sub each team. Fun Fun Fun! Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or just not so talented? Are you tired of over-competitive emotional bros who only want to show off their skills and desperately need to win? **Then [Lousy & Lazy Football](https://www.instagram.com/landlsc/) is the right thing for you!** We are a group of friendly people who just want to have a relaxed kick. All genders, ages (18+) and nationalities welcome. Note: **We** only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/). Rules for lazy & lousy football 1. **Don’t be competitive** 2. **No hard tackling/sliding challenges** 3. **Support new and less skilled players by giving them the time and space to play the ball, dont intercept passes to and from them** 4. **Don’t dribble past multiple players (trying to take on one player is fine).** 5. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.** 6. **Rotate the goalkeeper** 7. **Be a teamplayer, pass the ball.** 8. **We enjoy shooting goals, but we dont count them. Winning / losing doesn't matter.** This meetup is for members of the Lousy & Lazy Sport Club. If you want to try out our lousy & lazy sport events, you can do a trial run (Probetraining).

After-work bike ride: Ostkreuz → Köpenick and back. Shake off the workday with a relaxed evening ride to Köpenick. We'll cycle there, walk by the river, and stop at Freiheit Fünfzehn — a lovely summer garden where we can grab a snack or drink, chat, and relax. Then we head back via a different route. Any bike type works. No special experience needed - just show up and enjoy the ride Köpenick is a small town on the Spree. It's a great spot to walk along the river, explore the historic old town, catch a film at the outdoor cinema, or just have a beer at one of the riverside beer gardens. The ride itself is scenic too — you'll cycle through the beautiful Treptower Park and pass some atmospheric abandoned industrial sites. • Start & End: S-Bahn Ostkreuz • Distance: \~24 km (12 km each way) • Terrain: Flat, paved bike paths • Pace: The one you are comfortable with — we are here to relax after work, it's not a race • Recommended to bring: water and lights • Equipment: Up to you but you're responsible for your own safety. Food and drinks at the beer garden not included — pay your own. See you! 🚲

Average age is around 27-50. We play on grass using poles as goals, which allows us to adjust the field and goal size depending on the number of players. Please arrive on time, as we need to divide the teams. Game starts 11:30 sharp. Wir spielen jeden Sonntag - ganzjährig - und suchen nach ein paar Spielern, die sich vorstellen können, regelmäßig dazuzukommen. Alter im Schnitt ca. 27-50. Wir spielen auf Rasen mit Stangen als Toren, wodurch wir die Platz- und Torgrösse flexibel a die Anzahl der Spieler anpassen können. Bitte pünktlich da sein, weil wir die Mannschaften aufteilen müssen. Das Spiel beginnt pünktlich um 11:30 Uhr.

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️‍🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity. This time, we have the following topics lined up: * Tobias has been working on a ***project wizard*** and would like to receive some feedback from the group. * Crop is going to introduce the topic of ***atomics***, then hold a discussion space for answering questions and sharing experiences. * Raf finally would like to introduce ***test-driven development*** with a small mob coding exercise. If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 16 April 2026 is our thirteenth meeting. Our next projected meetings are going to occur on the following dates: * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 * 1 Oct 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/).

Dolly Sods is a rocky, high-altitude plateau with sweeping vistas and flora and fauna normally found much further north in Canada. A backpacking trip in this area will expose you to a very diverse and unique landscape with sphagnum bogs, grassy meadows lined by spruce trees, wind-carved boulders, and beautiful mountain vistas. Note - this area can have very unpredictable weather. I've had everything from sunshine, to heavy rain, to even snow and hail as late as May. Pack accordingly. **Trail Details:** We will meet at The Vienna Metro station on Saturday morning at 8am and drive to the Red Creek Trailhead at the southern end of the Dolly Sods wilderness. The drive is about 3 hours - I will drive and am happy to have up to 3 others carpool with me. When we arrive at the trailhead, we will hike about 6.3 miles to our campsite, stopping once to check out the the iconic Lion's Head on Breathed Mountain (pictured in the post). Should be an early day, so feel free to bring cards, adult beverages, or other items to pass the time. The second day, we will explore the rest of the park, which includes the rugged Dunkenbarger trail. The second day is about 9.4 miles back to the car. There are a ton of stream crossings on this trip - so expect to get wet and pack accordingly. **Essential Items**: * Tent * Sleeping pad​ * Sleeping bag suitable for expected temperatures​ * Backpack (appropriate for overnight backpacking)​ * Backpacking stove with fuel​ * Pot, cup, dish, and utensils​ * Dehydrated meals​ and snacks * Water bottles or hydration system (capacity for at least 2 liters)​ * Water filter or purification tablets​ * Headlamp with extra batteries​ * Rain gear * Dry bags or pack cover​ * Warm clothing layers (non-cotton) * Trowel for and toiletries for Leave No Trace compliance **Optional Items**: * Personal first aid kit​ * Map and compass or GPS device * Power bank or external battery * Trekking poles​ * Camp shoes * Electrolyte supplements​ * Alcohol​ * Books, games, or other enterainment * Gaiters​ * Sunscreen, lip balm, insect repellent​​ **General meetup location:** Vienna Metro Station - 8:00am Time driving: 3 hr. each way Google driving direction from Vienna metro: [https://maps.app.goo.gl/KUW283UFEe5kJJnLA](https://maps.app.goo.gl/KUW283UFEe5kJJnLA) **CARPOOL:** Don't forget if you want a ride or are willing to offer a ride – be a friend to the environment, save money, and make friends. **LIABILITY NOTICE:** Please remember that this group operates under the common adventurer model.

Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it. Driving is the best option. There is plenty of free on-site parking. Otherwise, we are a 22 minute bus from the Vienna Metro Station. Bicycling from Vienna is possible but difficult, though once you are here, there's a bike rack in the garage behind the building, and there's also a Capital Bikeshare dock 15 min walk away. **Sponsored by:** Thank you [Fairfax City Economic Development](https://gofairfaxcity.com/) and [Mason Enterprise Center](https://enterprise.gmu.edu/) for making this event possible! **Thank you so much to our wonderful sponsors!** Organized by [DMV Petri Dish](https://www.dmvpetridish.com/) **[Code of Conduct](https://github.com/NoVACodeCoffee/admin/blob/master/code-of-conduct.md):** We value the participation of each member of the community and want all attendees to have an enjoyable and fulfilling experience.
