Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. 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.

**Let’s have lunch and have some extra fun! Bring your favorite game! 🥳**

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at 7:00pm on Wednesday, February 11 at Streetlight Guild. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. **SCHEDULE:** 6:45ish - Quick introductions 7:00 - Timer starts: write for 1 hour 8:00 - The End **OPTIONAL SOCIALIZING** happens before and after the writing hour. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. **BEING LATE IS OKAY:** just show up and get settled! If you were on time, please be willing to make room for the friendly latecomer. Happy writing & I look forward to seeing you at Streetlight Guild! **WHAT SHOULD I BRING?** Whatever you need to be able to write! You're welcome to bring earplugs/headphones if noise will bother you! **OTHER IMPORTANT DETAILS:** * **RSVP:** Please RSVP by 6:00pm the evening of the meeting. This helps me know how many to expect, and if we'll need additional space! * **COVID:** While masks are not required, please be mindful of the other writers around you and their comfort levels. * **WIFI/OUTLETS:** Outlets are limited, so please ensure your devices are charged when you come! But Streetlight Guild does have free WiFi! Yay! * **PARKING:** There is free public parking at Streetlight Guild.

**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. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.

**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** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share

Model Context Protocol (MCP) is emerging as a standard way for AI models to securely interact with external tools and systems. This session provides a practical deep dive into MCP architecture, core concepts, and real-world integration patterns. We will explore how MCP enables structured tool calling, improves interoperability, and simplifies AI integration in existing applications. The talk will include examples of connecting AI models with APIs, databases, and enterprise systems, with a focus on how developers can adopt MCP in Java-based environments. **Note**: This is a hybrid in-person/online event. Food and social for those in the OCI training room starts at 6:00pm. Presentation starts at 6:30pm for those online and in the training room.
