Just when you thought you could stash the thermal leggings and show some skin - surprise! Winter took one look at your pasty knees and decided to cum again... This week’s trail promises the full Game of Thrones experience: cold winds, possible snow, and the vague sense that nobody will survive past the beer stop. Hares have bravely marked a scenic route through what used to be “springtime” but now promises to be full of that white sticky stuff we all love. Expect shiggy, frozen fingers, and the chance to reflect on your life choices while wondering if hot mulled wine counts as a balanced electrolyte replacement. Circle will be in the Platz next to Wipkingen Bahnhof and on-after will be Gelateria di Berna. **Where**: Wipkingen Bahnhof Mobility car **When:** We'll meet at 6:50 pm to start at 7:00 pm. There's a charge of CHF 5 for participating, which covers all you can drink beer/cider (and non-alcoholic alternatives) plus snacks afterwards. **All Welcome:** If you are new, curious, and want to get out of the house, stretch your legs, talk shit, enjoy a drink, and hopefully a laugh, then here's what you need to know: • We are a social running/walking group, physical fitness is not required, but a sense of humour is useful. • The aim is to find the '*Beer Stop*' at the end of the '*trail*' and have fun. • 'True Trail' is typically 4-7 km. Some will go less (especially those walking or walk/running), and some over-achieving fast runners will go further. • The '*Hare*', which changes each event (along with location), cleverly lays the trail (typically with flour marks) so that everyone reaches the end at the same time. • There is always a place to deposit your bag and sometimes a place to change. • **After Trail**, we group for \~20-40 minutes for drinks, snacks, and some fun. This '*Circle*' is typically outside, so leave something warm in your bag in winter (and bring a flashlight when it's dark). If you don't want to stand around drinking afterwards, you can head home. We occasionally all go to a restaurant afterwards. **Why bother leaving your warm & dry sofa?** If you enjoy getting outside, being around people, and doing something a bit different, you will probably enjoy hashing. Exercise is important, and this is probably the least boring way to get it. 'Hashing' and the idea of some physical activity to work up a thirst, have been around for almost 90 years and there are groups (*Hashes*) in most major cities. Its humor and 'traditions' can be explored on the internet - **or you can just come along and find out.** *See you there.* We are of many nationalities, all ages, full of misfits and idiots (at least there is no one taking themselves seriously!) and always welcome newbies 'Virgin Hashers' and visitors from other groups.

Dear All, This session is mainly for the people who want to learn kundalini yoga/meditation in a traditional way. Traditionally the master will transfer his/her kundalini energy to the student to activate his important chakras (energy centre) including Third Eye and Crown Chakra. The student can start to feel his/her Kundalini Energy is rising from their base of the spine and feeling the energy vibration(Consciousness) in the third eye (the space between the eyebrows) from the Kundalini Activation. This session is helpful for the beginners who want to learn simple yoga-meditation exercises also. This is a general session to experience your inner kundalini energy. But if you need proper kundalini activation(Shaktipat), then pre-registration is mandatory. **What is included in this session?** * Simple stretching practices for Hip and Spine (not complicated, even beginners can do) * Kundalini Breathing Techniques * Sound Energy (Mantra) Meditation * Energy Healing Techniques * Formal Kundalini Activation (optional and only for pre-registered people) * Chakra Meditation * Yoga Nidra (Relaxation) **Some of the benefits of Kundalini Energy Activation are:** * Keeps the body healthy * Mind attains its natural peaceful state, so the meditation becomes easy. * Breathing pattern will be harmonized * Stress release and peace * Clear & sharp intellect * More intuition * Inner happiness * Clairvoyance and Clairvision * and to the ultimate SELF realization (which will lead to the blissful state - our true state) with enough years of practise **DONATION BASIS** **About the Teacher who conducts this session:** The kundalini wisdom teacher Jayaprakash is from India. He is practising kundalini yoga for the since 2005 under the guidance of Self Realized Indian Master "GuruMahan". He is teaching kundalini yoga since 2008 as part of a non-profit organization "Maha Shakthi Yogam Switzerland". He teaches Yoga/Meditation/Pranic Healing/Stress Relief courses in various places of Germany and Switzerland. He is the authorized kundalini yoga wisdom teacher from UPF(India) to give kundalini initiations (Shaktipat) with the Grace and Protection of his Master. All these events are conducted for non-profit purpose. Donations are collected on behalf of Swiss non-profit organization (Verein) "Maha Shakthi Yogam - Switzerland" **Eligibility:** Anyone can attend the session even if they don't have previous yoga/Meditation experiences. **Dress:** Wear a comfortable dress if possible yoga dress. We provide the yoga mat. **Please RSVP only you are really interested and coming ! Limited Seats !** **About Kundalini Shaktipat:** In every human being there is a source of natural energy that the yogis call the kundalini. In order to evolve in the yogic path, no matter what our path, the kundalini must be active. For most of us, the kundalini lies dormant at the bottom of the spine in the base chakra known as the Muladhar. When it awakens, it ascends through the chakras until it reaches the highest chakra, the Sahasrar. When that occurs, we merge with our True Self and attain SELF realization (our true nature). Shaktipat is the transfer of spiritual energy from the teacher to the student in order to awaken the kundalini. This process is compared to lighting one candle with another that is already lit and glowing. When the teacher is connected with the fully realized master and the energy is completely within his or her control, shaktipat initiation ensures that the student’s energy will remain active and stable. "Electricity is present everywhere, but there can be light only when the switch is turned on. Similarly the true master manifests the consciousness in the disciple through shaktipat.” **HAPPINESS is our TRUE Nature, which comes from within not from outside !**

Web Zurich presents inspiring talks all about the web. Join us for the March 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat and introduction 19:00 \~ 19:40 *Christian Heitzmann* **Why Documentation Won’t Write Itself—and AI Won’t Save You** For the last 15+ years, I’ve joined and consulted software teams that all struggled with the same problem: nobody likes writing documentation, and everybody pays the price for it. New developers spend weeks reverse-engineering codebases, architecture lives in people’s heads, and wikis quietly decay into noise. With AI now entering the picture, many hope it will fill the gaps. It won’t. I’ll show the simple ideas that change everything: how to think about documentation in the right levels, how to keep it close to the code, and how to avoid the decay we all know too well. These are the decisions that have to be made before any tool or process can work. The documentation won’t write itself. But there are ways to make it far easier and far more reliable. 19:40 \~ 19:50 **Short Break** 19:50 \~ 20:10 *Marco Gähler* **How to write good code** There is an infinite amount of solutions how you can solve a programming problem. Some are better, others are worse. The best solutions are easy to understand, maintain and errors are not able to hide. I wrote a book "Software Engineering Made Easy" about this topic and I'm more than happy to explain some principles that make your code better. Most of them are quite simple to understand, once you understand the mechanics, why your code always breaks. 20:10 \~ 20:30 *Marius Ishida* **AI: The Lightsaber Problem** My talk will challenge the popular narrative that AI fundamentally democratizes power by showing that, which I believe is not true at all. While generative AI lowers entry barriers for basic tasks, it disproportionately amplifies the productivity and leverage of already computer literate users. Empirical research shows that AI acts as a skill multiplier rather than a true equalizer, with outcomes strongly dependent on users’ ability to frame problems, verify outputs, and integrate tools into complex workflows. As a result, AI risks reinforcing a new AI driven digital divide, where technical literacy—not access alone—determines who truly benefits. 20:30 onward More drinks & chat We look forward to see you there!

Welcome cold lovers! We have been practising cold water plunges for over 4 years. We believe in the benefits of cold water exposure. The feeling you get after the swim is magnificent, it makes you feel alive. We have started this group to safely experience the cold water together. We motivate each other, do active warmup exercises, and also share our life stories with a warm coffee/tea afterwards. The event is every Sunday at 11:30, we meet at the Mythenquai Badi entrance no matter the weather. Take along: a large towel, comfortable bathing suit, flip-flops, and warm clothes (hat, gloves, etc). If you’re planning swimming out take along a bright swim buoy. The event is Free. IMPORTANT: Every participant takes responsibility for themselves when attending this event. Before attempting cold water exposure, individuals with health conditions (e.g., heart problems or hypertension) should seek advice from a healthcare professional. Safely acclimating the body to cold temperatures requires preparation and gradual exposure.

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!

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

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.
