**THE POWER OF THE SUBCONSCIOUS OVER YOU** You are welcome to arrive 15 minutes early for refreshments! At the lecture "The Power of the Subconscious", the speaker will clearly and understandably explain topics such as: What is the exact definition of the Subconscious Mind? How does it inflict unwanted feelings and anxiety in you? What determines how much pressure it exerts on a person? So many of us find ourselves feeling anxious, struggling with self-confidence and overthinking many of life’s choices. What exactly is the goal of the subconscious? This is not just a lecture where you sit quietly and listen. It's interactive and LIVE, so you can ask questions at any time. And the most important topic: **HOW DO YOU TAKE CONTROL OF YOUR SUBCOUNSCIOUS!** This group is sponsored by the Dianetics Life Improvement Center.

***Please read all and make sure you agree before you sign up.*** **Court Type:** Outdoor Sand **Level:** intermediate (BB) **Transportation:** Parking will be right by the sand courts, behind the courts, and there is garage parking close to the courts. Metro is the Blue and Yellow line. **What to bring:** at least 3 bottles of water and a ball if you have one. **MAX:** 10 players per net. (1 Net-small court) **Restroom:** Restrooms are across the street in the restaurants. **Host's Philosophy on This Event:** The purpose of this meetup is to create a fun and supportive environment where we can improve our skills, enjoy competitive games, and connect socially. While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. That’s why the title doesn’t include “competitive” or “social”—we want a healthy mix of both. This is a space where you won’t be judged for making mistakes. ***We do expect you to listen to the organizer if they make suggestions or adjustments***. We also expect a mindset geared toward learning and getting better over time. That said, this event isn’t intended for beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level. **Skill Level:** 1. **If you want to know your level, please see the link below:** [Smiley Social Volleyball Levels](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/edit) **YouTube:** The games may be recorded and uploaded to our channel here: Let the host know if you have issues with this ahead of the event. [https://www.youtube.com/@mp02626](https://www.youtube.com/@mp02626) **ATTENDANCE:** **Player Selection:** Regulars > Your Vibe > Smiley Flaky Ratio\* > Skills > New Members > New Member with a +1. The host takes attendance very seriously. Please remove yourself from the event (if you can't make it) as early as possible to allow others to join. You will be marked as a ***no-show*** if you don't show up to the event. One no-show means you will be removed from the group. See the rules below. **\*The organizers can see the number of times you have attended events vs the times you have dropped out. If your drop rate is more than 50%, you may not be accepted to the going list.** [Smiley Social Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/edit) **Q&A** * Bringing your **dog** is welcome and encouraged. * *Can I be late or leave early?* The host expects you to be there **on time** and leave on time. If you need to arrive late or leave early, please let the host know in advance. * *Can I come even if I am not on the going list?* No * Why max the players at 10 when you can do 6v6? This court is already for 2v2; getting 6 players on each side is overkill. * How can I become a regular if I don't ever get to attend? You can attend my other events. Show me you have good skills and bring good vibes! **Smiley Social documents:** 1. [Group Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg) 2.

Hey Poetry Lovers! This group is on a roll. Here’s the gist: We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week. For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form). Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

Socrates Café meets twice a month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian

Let's get together to play some competitive quads and doubles volleyball. **COST**: FREE **Court Type**: Outdoor grass **Minimum Skill Requirements**: Intermediate (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is **NOT on a first come-first serve** basis and players with higher skill level and players who can bring a net/ball will get priority over others on the wait list. 2. Since skill levels are **self-reported**, some new attendees may not meet the expected level. For doubles, we encourage you to choose a partner you can enjoy the game with, and since this 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. 4. Please answer all questions, so it's helpful for us to organize the event. **Smiley Social documents:** 1.

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.

Communication is everything in life You are only as successful as your ability to communicate. \- What if you could confidently talk to anyone? \- What if you had the ability to calmly control every conversation? \- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence? You can! The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate.

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.

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!
