**AI is becoming part of many documentation workflows, but how do you turn that into a clear, repeatable strategy?** At this month’s meetup, we’ll focus on how to build an AI docs strategy by identifying gaps in your current approach, creating practical playbooks, and using automation to support consistent, scalable documentation. In this session, [Maddy Onyehara](https://www.linkedin.com/in/maddalena-o-bb2372020) (Technical Writer, Cloudflare), [Jun Lee](https://www.linkedin.com/in/junlee98?utm_source=share_via&utm_content=profile&utm_medium=member_ios) (Senior Technical Writer, Cloudflare), and [Anita Achu](https://www.linkedin.com/in/anita-achu?utm_source=share_via&utm_content=profile&utm_medium=member_ios) (Technical Writer, Upsun) will walk through how to approach AI in documentation in a structured way. This includes spotting where current workflows fall short, designing playbooks teams can rely on, and introducing automation that improves quality without adding unnecessary complexity. 🔔 **Note** Please note: spaces are limited, so please RSVP only if you’re able to attend and free up your spot if your plans change. 🗒️ **Agenda** **When**: Thursday, 21 May, from 6:00pm **Where**: The Gallery @ [The Corner](https://maps.app.goo.gl/xegvGx3qA9ysEgvA6) (42 Adler Street, E1 1EE) **What**: **18:00 - 18:30** Arrival **18:30 - 18:40** Welcome & Housekeeping **18:40 - 19:00** Presentation from our sponsor, [Document360](https://document360.com/) **19:00 - 19:50** Session: Build Your AI Docs Strategy **19:50 - 20:00** Q&A **20:00 - 21:00** Networking All times are approximate. **📍 How to find us** Enter the hotel, turn right, and pass the bar to find The Gallery meeting room.

On this photo walk we will be exploring the vibrant Shoreditch area, taking in Spitalfields Market, Brick Lane, and some quieter back streets. We’ll work our way through the creatively rich area with plenty of street art, texture, and street photography opportunities along the way. It’s a busy, visually rich part of London, so there’s always something happening — candid moments, details, layers, and vibrant colour. Beginners and experienced street photographers welcome.

Join us for a special edition of Deeper Discussions, where we dive into thought-provoking **fiction** that challenges perspectives, sparks imagination, and opens doors to meaningful conversations. Whether you're a lifelong reader or rediscovering the joy of novels, this is a space to explore stories that stay with you long after the final page. **This Month's Book - One hundred years of solitude by Gabriel Garcia Marquez** One Hundred Years of Solitude follows generations of the Buendía family in the fictional town of Macondo. It blends everyday life with magical, surreal events in a dreamlike style. The story explores time, memory, and the repeating patterns of family life. **How does it work?** * Brief introductions and reflections on what struck you most * Moderated discussion exploring plot, themes, and characters * Open conversation where different interpretations are welcomed ️ * We wrap up by sharing insights and connections made **What to Expect?** **Close Reading:** We go beyond surface-level plot summary. Expect discussions that examine the author's choices, narrative techniques, and the questions left lingering in the silence between pages. **Thoughtful Dialogue:** This isn't a race to share opinions—it's a space for genuine exploration. We listen, we reflect, we build on each other's insights. **Meaningful Connections:** Great fiction holds up a mirror to the human experience. Through discussing characters' choices and moral dilemmas, we often discover something about ourselves and each other. **How to get the most out of this event?** **Finish the Book:** Please attend only if you've completed the book. Spoilers will flow freely, and the richest discussions come from those who've made the full journey. **Ground it in the Text:** Bring your interpretations, but anchor them in what's actually on the page. Quote passages. Reference scenes. Let the author's words guide us. **Respect & Openness:** Every interpretation matters. Make space for quieter voices. Challenge ideas, not people. Stay curious rather than defensive. **Why a Fiction Book Club?** **Explore the Human Condition:** Fiction lets us inhabit lives we'll never live, forcing us to confront questions about identity, morality, love, and loss. **Sharpen Your Thinking:** Close reading develops critical thinking—noticing what the author chose to include, exclude, and how the story is told matters as much as what happens. **Deepen Connections:** Discussing characters' choices and moral dilemmas creates surprisingly intimate conversations with fellow readers. **Who is this event for?** * You find yourself thinking about books long after you've finished them * You want more from book discussions than "I liked it" or "I didn't" * You're curious how others interpret the same story differently * You value thoughtful dialogue over debate ️✨ * You're looking for meaningful connections with fellow readers **What's in it for you?** * **Fresh Perspectives:** Discover interpretations you'd never have considered alone * **Deeper Understanding:** Unpack themes and symbols that enrich your reading * **Genuine Connection:** Bond with others over shared literary experiences * **A Space to Think:** Slow down from the noise and engage with ideas that matter **Ready to dive deeper into stories that matter?** Join us for an evening where fiction becomes a gateway to understanding ourselves and each other. ✨ **We really hope to see you there!** **About Deeper Connections** We have a mission at Deeper Connections to improve the quality of people's lives through conversation. All our events are centred around the concept of connecting deeply, because we believe we all deserve to be seen, felt and understood for who we really are. To have the 'deeper conversation' approach when relating with others can change our lives and can change the world. **Our Values** * **Respect:** Treat everyone with kindness and consideration. ❤️ * **Open-mindedness:** Be open to different perspectives and ideas. * **Active Participation:** Share your thoughts and engage in meaningful discussions. ️ **Staying in touch** Interested in finding out about all the events sooner than on Meetup or staying in touch beyond the events, you can join our WhatsApp channel and community using [Deeper Connections WhatsApp Channel](https://whatsapp.com/channel/0029Vb6CBAdIN9ijrEYdv33z) [Deeper Connections WhatsApp Community](https://chat.whatsapp.com/EqGsmF3021RKTwBpGcuR80) **Keep This Event Free** If this event brings you something meaningful, you can help others access the same transformational experience.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

**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** TBD

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
