....aaaaand we are back in the water also this year!!! Kayaking around the city channels is one of the most enjoyable activities in Copenhagen on a sunny day. GreenKayak, a NGO dedicated to raise awareness to ocean pollution, makes few (open) kayaks available across the city to paddle and help collecting waste floating in the water. Open kayaks are typically easier to manovre than other types, and do not require EPP2/EPP3 patents. I booked 2 double kayaks for 4 ppl in total. It is possible to use the facilities at Kayak Republic free of charge: restrooms, lockers and showers. **REQUIREMENT** \- Safety first \- Need to be able to swim comfortably \- Waterproof gear preferable \- Sun lotion and sunglasses \- Change of clothes in case yours get a bit wet during paddling \- Towel\, if you want to shower or just in case **COST** Unfortunately, due to the frequent last minute cancellation last summer, it was challenging backfilling participants with short or no notice, and it was very disrespectful to the group and GreenKayak NGO. **To reserve your spot, please transfer 150 kr. to my mobilepay 25717293**. The amount will be returned to you if you show up on time, or the event is cancelled for other reasons; **this remains a free non-profit event**. The kayak rental is free of charge provided that: \- we are able to pick\-up some waste during our paddling activity \- we share our experience on the So\.Me \#GreenKayak **AGENDA** 11:50- Meet up - please be on time 🙂 11:50-12:00 Briefing and getting ready 12-00-13:45 Paddling around Copenhagen channels and return to the start point 13:45-14:00 Return the equipment to Kayak Republic **DISCOMFORT LEVEL** \- 3/5 **TO LEARN MORE** [GreenKayak](https://www.greenkayak.org/)

Malmö has a nature reserve in the city! However it can only be accessed with a guide from Malmö stad. You'll need to reserve your spot for the tour by buying a symbolic ticket via this link: [https://www.kulturcentralen.nu/evenemang/limhamnlimestonequarry-joinaguidedtourinenglish](https://www.kulturcentralen.nu/evenemang/limhamnlimestonequarry-joinaguidedtourinenglish) It costs 10 kr. Note that the sale opens one month before the event, on April 24th at 9am. Make sure you pick the right date (May 24th). Spots sell fast, so if you are eager to join, make your reservation early in the day. Since it's a public tour I have no idea how many spots are available. It's first come first serve. The reserve comes with restrictions. One of them being: it is not allowed to walk or stay outside of the assigned paths and areas. Another being: it is also not allowed to bring pets or drones and other aircrafts. After the tour, for those who are interested, we can walk around the quarry, it's 4km. There are viewpoints with nice view of the area, see featured photo. The tour lasts for 2 hours. The duration of this event is including the walk around the quarry. Limhamns kalkbrott has been a nature reserve since 2011. It used to be a mining area, but nature has been roaming free since 1994, when the operations closed down. What to bring: water could be good, and also sunscreen. Dress according to weather. How to get there: The quarry is easily accessible by bike. Public transportation: City bus 12 arrives at bus stop Sibbarpsvägen at 14.39 from the north. From there it's a short walk to the meeting point and gate. By car: There's a parking lot by the gate to the reserve and our meeting point. Note that the **gates** for entering with the guide **close** at 3pm **SHARP**. Come early!

End time is approximate, let's take our time to enjoy the sounds of this rare toad, and views of Lomma bay from the shoreline. Please change your rsvp as soon as possible when you have decided to no longer attend. In Malmö there are two thriving locations with this otherwise rare species. May is the time for the European green toad to mate. We will keep our ears out for their calls. On this event we will meet in Oljehamnen in the vicinity of bus stop Svartögatan, go for a walk along the shoreline, enjoying the views of Lomma bay, and reach a place called Paddeborg, a pond where these toads are supposed to hang out, to enjoy their song. Perhaps even catch a glimpse of them. When we are satisfied after sunset we will head back to the bus stop. What to bring: 🐸 something to sit on 🐸 water for the walk 🐸 dress according to weather 🐸 patience and silence Getting there: By bike: Meeting point is accessible by bike from Malmö Central Station. By public transportation: City bus nr 35 arrives at bus stop Svartögatan at 20.10. By car: Find a parking lot at a suitable spot in the vicinity of the bus stop.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. 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.
