Let's get together to play some competitive coed doubles volleyball. **COST**: FREE **Court Type**: Outdoor grass **Minimum Skill Requirements**: Solid BB (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is **not always on a first come, first served basis**. [Good doubles partner](https://docs.google.com/document/d/14weEw-P52XKx0P8K2l-ZOFtYU61wmfdkSkopbG5avro/) and those who can bring a net and ball, may get priority over others on the waitlist. 2. Since skill levels are **self-reported**, some attendees may not meet the expected level in reality, so we encourage you to choose a partner you can enjoy the game with, and since this is a **competitive** event, it is okay if you make a strong team and win all the games. 3. Each person must help set up and take down one net, leaving some nets unset for latecomers. **Smiley Social documents:** 1.

Join us for a discussion of ***The Anthropocene Reviewed: Essays on a Human-Centered Planet* by John Green.** Here's the summary: The Anthropocene is the current geological age, in which human activity has profoundly shaped the planet and its biodiversity. In this remarkable symphony of essays adapted and expanded from his ground-breaking, critically acclaimed podcast, John Green reviews different facets of the human-centered planet - from the QWERTY keyboard and Halley's Comet to Penguins of Madagascar - on a five-star scale. Complex and rich with detail, the Anthropocene's reviews have been praised as 'observations that double as exercises in memoiristic empathy', with over 10 million lifetime downloads. John Green's gift for storytelling shines throughout this artfully curated collection about the shared human experience; it includes beloved essays along with six all-new pieces exclusive to the book. **Let’s meet at Caboose Commons in Fairfax to enjoy some good discussion and meet new friends.**

TRADING THE DANCE FLOOR FOR THE TRAILS The disco lights are taking a breather, but Social Sips & Bites is keeping the high energy alive in the great outdoors. We are hitting the trails, and the timing couldn't be better. National Park Service is waiving its usual vehicle entrance fees for Free Entry Day, so we’re bringing the whole DMV community together for an epic morning of fresh air, jaw-dropping views, and massive group vibes. Whether you’re recovering from the last party or prepping for the next one, this is the perfect excuse to get outside, move your feet, and meet some incredible people. From the rushing waters of the Potomac to the winding, shaded dirt paths, this isn't just a walk in the park. It’s a chance to unplug, swap stories with familiar faces, and explore one of the absolute best natural wonders right in our backyard. No RSVP cap, no exclusive guest list. Just good people, great views, and unmatched Sunday energy. See you on the trail! 🙌

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.

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: In this session, we will explore the concept of hyperdimensional computing (HDC), a brain-inspired method of computing. We'll begin by talking about neurons and the brain. Through simple Python examples we’ll dive into HDC and answer: What it is? How does it work? And, how does it learn? We will review how other researchers have applied HDC and demonstrate how it can be used for solving cybersecurity tasks. Where deep learning fails, HDC excels. No supercomputer? No problem. HDC offers interpretability, low energy requirements, robustness to errors, online learning, on-device learning, and more. By pushing the difficult calculations into the embedding process, learning becomes a cinch. By the end of this talk, attendees will have everything they need to teach their own hyperdimensional computing models. We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com

You can sleep in on the Semiquincentennial (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.

We have moved to guild.host. Look us up there. https://guild.host/events/buckeye-cocoaheads-rcavwd

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way.
