Wednesday is karaoke day. Every Wednesday we gather to sing. Come with a friend or alone, with or without a voice. The format is simple: show up, grab a microphone, and sing whatever you want. Or don't sing, just support others. As usual, the meeting place is Top Club. If you haven't been before, you can get to know the space at the same time. We're looking forward to seeing you this Wednesday. See you there! Trešdiena ir karaoke diena. Katru trešdienu mēs pulcējamies dziedāt. Nāc ar draugu vai viens, ar balsi vai bez.

## Riga Philosophy Discussion Meetup #4 Welcome to an open philosophy discussion for curious minds, thoughtful conversation, and respectful debate. This event is where people from different backgrounds gather to exchange ideas, challenge assumptions, and explore life’s bigger questions together. The purpose of this meetup is not to “win” arguments or prove others wrong, but to think deeply, listen carefully, and enjoy meaningful conversation. Whether you are new to philosophy or have studied it for years, everyone is welcome. **Topics may include:** * *Ethics and morality* * *Consciousness and free will* * *Meaning and purpose* * *Technology and society* * *Politics and human nature* * *Happiness and suffering* * *Logic, reason, and belief* * *Artificial intelligence and the future* * *Classic philosophical ideas and modern dilemmas* For our fourth meetup, we will begin by proposing several discussion topics. The group can then vote, and by majority we will explore whichever topic generates the most interest. Possible discussion topics: * *Are humans naturally good or selfish?* * *Can happiness be the highest goal?* * *Ethics of artificial intelligence* * *Is ignorance bliss?* * *Should emotions guide decisions?* The format will be informal, open, and conversational. Everyone is encouraged to participate, ask questions, and share perspectives respectfully. **Simply look for the table with the small Latvian flag on it outside.** (or inside if the weather is not so nice) *Note: The conversation and all discussion will solely be in English.*

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.

Our next much-awaited **COLUMBUS** meetup is **Tuesday June 30th from 7-10 pm EST at ACE OF CUPS**.

Hope you will be there too! Save the date and pass the word. **Please RSVP** so we know who is coming and how many to expect. Find us to say hi and we will introduce you to others. We should be easy to spot. (The happy-looking group wearing cool nametags! See photos from our past events.) Sign in, grab a name tag, start your own bar/food tab, meet old friends and make new ones! Everyone is welcome. SEE YOU THERE!

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.

We are recruiting new group leaders for virtual men's groups! Our primary groups are outdoor movement groups, but we are launching virtual groups for the state of Ohio and beyond and the groups will move outside in the spring, creating room for men's groups, women's groups and coed groups all over the country. Read below to learn about our groups and click the links at the bottom to apply. ### **What is an Outdoor Empowerment Group?** Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being. Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment. ## **Why Join?** * **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance. * **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space. * **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection. ## **The Ideal Group Leader** The ideal group leader * Has a born-in passion for mental health, movement, connecting with nature and building community. * Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us. * Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind. * An ability to manage groups with high emotional intelligence and desire for human connection. * An ability to self-motivate and market/promote their group on Facebook and other social platforms. * Nature informed therapy or clinical therapists/psychologists a plus. ## **Our Impact**  Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported: * A noticeable improvement in mental clarity and emotional well-being. * An increase in social connection and a sense of belonging. * Said they would return again. We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself. ### **Why Our Groups are Donation-Based** Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission! Every contribution helps us: * **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization. * **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year. By choosing to contribute, you’re not just leading an event—you’re helping build a mental health movement that supports long-term well-being and connection for all during a severe mental health epidemic. ## **Come Join Us!** We’d love to have you be part of this growing community of people prioritizing their mental health, movement, and connection. 🔹 **Visit Our Website to Learn More:** https://speakyourmind.men/joinusoutside 🔹 **Apply Here to Lead Your Own Group!** – https://form.jotform.com/taketimespeakyourmind/sym-group-leader-application 🔹 **Support the mission**: If you resonate with the mission and want to support, feel free to join a group before applying or donate to help us reach our goals to help more people!

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
