I am proud to announce that we having our jam at the Temple Of Art & Music in Elephant & Castle!! 20 Second Chain: A structured improvisation format where a musical “chain” unfolds organically, with each player responding to and building on what came before. Lineup (on stage together): * 2 guitarists * 1 bass * 1 drummer * 1–2 singers * 1 additional instrument (sax, trumpet, percussion, etc.) How It Works: 1. All musicians on stage are assigned a number, which determines the playing order. 1. Playing order, a key (and available chords) is written on a whiteboard opposite the stage. 1. Number 1 begins alone with a simple idea for 20 seconds — leave space for others to build. 1. Every 20 seconds, the next numbered musician joins one at a time, layering something that complements what’s already happening. 1. Once everyone has entered and the full band is playing, the group improvises for 5 minutes, developing the groove — complexity and solos can grow naturally. 1. No on-stage planning — listen and respond in real time. 1. After the timer ends, the group rotates and a new chain begins. The Temple Of Art and Music is a live music venue and bar in Elephant & Castle so I encourage anyone attending to bring friends as it will be great fun for them even if they are not playing. The venue has a PA system, drum kit, mics and guitar/bass amps. There is no guarantee that there will be cymbals or drum accessories with the drum kit at the venue. Drummers please being your own if you can. Like all our other jams it will be a chance to jam with other musicians playing the music that you love in a gentle environment with no judgement and no pressure. This jam also uniquely gives the opportunity to play in front of a crowd! Tickets are **£10 online** message us let us know what instrument you play and we will confirm if there is space and send you the Eventbrite link for the jam. Please do not hesitate to contact me for more information about this jam and London Jam Sessions. At London Jam Sessions we have an active community on WhatsApp where we all discuss the upcoming jams and future events. Everyone in the community is encouraged to ask questions and bring forward new ideas. Dm me and I can add you to our Whatsapp group. I might take some photos and videos. If you prefer to not appear on photos or videos let me know.

Sunday rehearsal with Castellers of London. Meet us at the OBC Community Centre to help build human towers! This get together is a great opportunity for you to meet new friends, socialise and have a go and explore your abilities as a human tower builder a.k.a Casteller! For newcomers we have a team of trained Castellers who will introduce you to the group, guide you through the activity and help you safely take part in this unique Catalan tradition. When you arrive just approach us as we are really friendly! If in doubt ask for Cuss! Please let us know if you are bringing guests. After the rehearsal we go to a nearby pub for social drinks where everyone is welcome :) What do you need? 1. Ideally a cotton shirt: to protect your neck and shoulders, the more durable the shirt/top the better. We do not recommend any thin items of clothing! 2. Jeans: allowing you to move freely without breaking. 3. Mask: We still require the use of a mask as you will be very close to your fellow Castellers - basically you will be hugging people! The rest of the equipment is on us! We take health and safety very seriously, both in relation to COVID-19 and also the activity- please be assured that the safety of all participants is of the utmost importance to us and we take all necessary precautions to minimize the risk, ensuring we all have a great time! Our regular members won't be filling in the Meet Up to say they are going 🙂 So don't be put off if you see only a handful have said they are going. A minimum of 25 on the day is normal. What the Meet Up may show is how many new people like yourself are going.

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

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.

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!

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *July Meeting - Lightning Talks!* Lightning talks are very short presentations on a topic of your choice (must be related to .NET). Talks should be 15-20 minutes in length and include minimal slides and quick demo (no live coding please). There will be 6 slots available! First come, first serve! **YouTube Link** TBD
