Hi friends, Thank you all for joining our discussion events over the past two years. It's very fun and rewarding for the community. Sadly, I've decided to step down as the group organizer by the end of June due to other commitments, so this celebration lunch will be the last event I organize for this group. I will still be around, but I just won't be able to organize any events in the future. Also, if you are interested in taking over as the organizer for this group, please reach out to me. Thanks.

Come join us for in-depth discussions on topics relating to moral and political philosophy. This is a group for members who are comfortable discussing topics that are often anxiety producing and controversial. *"Aristotle was a realist who believed that reality and knowledge are found in the physical world, accessible through sensory experience and logic. This led to contrasting views on ethics, politics, and the nature of reality itself. Plato emphasized abstract, ideal concepts, while Aristotle prioritized empirical observation and the study of the natural world."* \- Google Gemini Following Aristotle's lead, this group will lean heavily on empirical data to make arguments. The Socratic method is still the preferred way to engage in conversation, and Platonic Idealism is still relevant to the conversation as points of reference.

Capoeira (capo-way-ra) is an Afro-Brazilian martial art that is unlike any other martial art. Capoeira incorporates flowing movements with kicks, dodges, and some acrobatics. It is often mistaken for a dance for those reasons. Since it’s origins in the 17th century, it has evolved from a secret fighting practice into an art emphasizing self-expression and community celebration. It is great for the body and mind! In addition to gaining strength and flexibility in class, students learn about Brazilian culture, history, and language (Portuguese). On November 26, 2014 capoeira was granted a special protected status as "intangible cultural heritage” by UNESCO. No need to have a Capoeira background to join this class, just an open mind to try out a new way to move! Beginners welcome. **Please reserve your spot at www.piesfitnessyoga.com**. The session is offered InStudio only. **Sign up for sessions must be made at least 2 hours prior to class.** The address is 1322 Prince St. Alexandria, VA 22314. Our entrance is located on the side of the building, parallel to West St. **Street parking is available and additional parking is located at Shiloh Baptist church, spaces 3,5,7,9.** The church is located across the street from the studio, on the corner of Duke St. and West St.

**MLK Library - Room 302E** So many of us have a bucket list of things we hope to do or achieve before we “kick the bucket”! But do we also need to consider creating a spiritual bucket list – not just a list of things we want to do, but of things we want to be? And do we wait to one day just become these things, or are these things we can – and should we – be working on right now, day by day? What makes a bucket list meaningful is that it be a reflection of what you value and desire – a tool to help push ourselves to grow and develop and fulfill our highest aspirations. Things like skydiving, traveling, running a marathon, and buying a house are common to-do’s helping us achieve our material aspirations. But what about considering our ultimate to-do’s to fulfill our spiritual purpose? What if we aspired to grow spiritually, to be kinder and more virtuous people, to help others in need? Do we need to wait for some future time to do these things, or can we actually draw closer every day to achieving these goals through our daily choices and spiritual habits? What would it look like to live a life designed around reaching these spiritual goals and reaching our true, spiritual purpose? How can we support each other in checking off our spiritual bucket lists? Come join a different kind of conversation – one that welcomes every perspective in a search for the deeper truths that unite us – as we discuss the spiritual perspective offered by the Bahá’í Teachings on fulfilling our spiritual purpose. Please join us for a lively discussion as we explore how we can each live a life of spiritual growth and fulfillment and create communities that support each and every one of us. *“Material progress insures the happiness of the human world. Spiritual progress insures the happiness and eternal continuance of the soul.”* – Bahá’í Teachings **\*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.**

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.

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out.

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.
