Hello dear Challengers, if you wish to join the Limmat swim and strengthen your body, join me to that swim. I will give you a short introduction on the "why" you should do it and then you will tell me if you want to do it. I am a trained lifeguard (SLRG), I did also the Hypothermia Module and I am swimming in the cold since 2015. Take with you all the necessary to swim, flip/flop, safe buoy (something like the orange donut here below, if you have it) and a Thermos. https://secure.meetupstatic.com/photos/event/a/a/7/5/600_466843637.jpeg See you there! Massimo ps: Limmat temperature https://www.zh.ch/de/umwelt-tiere/wasser-gewaesser/messdaten/wassertemperaturen.html

Sessions of **individual runic readings** are available for beginners all along summer, both online (75 CHF) and offline in Zurich (100 CHF). These sessions are **NOT** esoteric or divinatory. We're approaching runes as **a symbolic system of archetypes** to examine any situation or question that is currently relevant to you. *If you feel stuck in a situation and cannot see a way forward, are facing a difficult decision, navigating a period of uncertainty, or trying to understand a recurring pattern in your life, a runic reading may offer a different perspective.* **You will receive:** • a clearer and systemic understanding of what is actually happening; • insight into hidden influences affecting the situation; • a better understanding of why certain difficulties keep repeating; • greater clarity around available options and their likely consequences; • practical ideas for what to do next. For registration and payment details, send me a direct message or fill in this form [The Alchemist Lab - Contact](https://alchemistlab.ch/Contact)

Unwind after work, clear your mind, and immerse yourself in a world of color – that's what this 1.5-hour acrylic painting workshop is all about. "After Work Flow" is a creative space where you can find peace, leave everyday life behind, and fully embrace the moment. No prior experience is necessary – just the desire to try something new and engage with color and movement. On a 30 x 30 cm canvas, you'll discover the freedom of abstract painting. There's no right or wrong, no perfect or imperfect – only your personal expression. You'll learn how colors interact, how they mix, overlap, and create new moods. It's not just about the result, but above all about the process: feeling, observing, and letting go. A special focus is placed on getting to know colors intuitively. You'll be surprised how individual hues change when combined and how much emotion can be contained in a single area of ​​color. Step by step, you'll develop your own abstract painting and learn to let go of preconceived notions. Brushstrokes also play a crucial role. You'll discover different ways to apply paint – calmly, boldly, softly, or with texture. Each brushstroke becomes a movement that lends depth and character to your painting. You're encouraged to experiment, try things out, and find new forms of expression without pressure or expectations. The workshop invites you to enter a state of flow – a place where time ceases to matter and you become completely immersed in the creative process. This is precisely where relaxation arises: when you detach yourself from your thoughts and simply allow yourself to drift. All materials are provided, including a 30 x 30 cm canvas, high-quality acrylic paints, and all necessary tools. At the end, you'll take your own abstract artwork home – a memento of a short creative break just for you. "After Work Flow" is more than just a painting course. It's a break from everyday life, a moment for yourself, and an invitation to experience color anew.

Welcome to the **Task-Buddies** event of the **Zürich Productivity Circle**, where we bring together like-minded individuals to work on personal goals and share the experience of growth in a supportive community. Maybe you are building a business or side hustle, studying for a course, learning a new (programming) language, figuring the tax system out, writing code, prose, or poetry, researching new stocks for your portfolio, tackling your German homework, or upskilling for your job. In all of these cases and more, this is the perfect space for you. In fact, productivity does not end there. Even if you just want to read a psychology book to resolve a personal struggle, sketch a mountain, listen to podcasts, organize your week, respond to unanswered emails and messages, enjoy a novel, or just reflect and meditate, you are very welcome here. For any task that adds positively to your life and can be done sitting down with others (exception: anything noisy/disruptive/disrespectful), you will fit into the events. We will meet at a work-friendly café in Zürich and follow the agenda below. **Agenda:** * **Introductions and food (20-30 mins):** Start with a round of introductions to get to know each other and share what we'll be working on, buy our food and drinks (alternatively one can also buy them later on). * **Productive Work Session (1-2 hours)** Dive into your individual tasks in a focussed, distraction-free environment. * **Collective Break and Socializing (\~15 mins):** Take a planned break to stretch, chat, get more coffee, and share insights about your projects. * **Continued Work Session (1-2 hours):** Get back to your tasks with renewed focus and motivation. * **Wrap-Up and Reflections (15+ mins):** Conclude with a reflection on what we accomplished, share productivity tips or questions, discuss plans for future meetups, stay back for more chit chat if you like. **What to Bring:** * Your project or task materials (laptop, charger, books, sketchpad, pen, etc.) * Respectful and kind demeanour * A positive attitude and a willingness to share and learn **Note:** Please ensure that your tasks are suitable for a quiet, communal setting.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ 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!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
