Cups of Code: Connecting the Community

A fun and light code session where tech friends get together in a large and relaxed café space, and code! Bring your laptop (or another coding device of choice) for a great opportunity to ask questions, share ongoing projects, help each other out, and meet other awesome coders. We're all about the code, and we hope to make a space for people who like to build. Notes to keep in mind: \Guest wireless internet access is good and free Come out and work, help, or just hang out!

# ☕ The OG Coffee&Code Meetup ### A Blockspace Community × Coffee&Code Collaboration Before the hype. Before the buzzwords. Before “AI-powered everything.” This is The OG Coffee&Code—the meetup that started it all, now presented in collaboration with the Blockspace Community. No panels. No pitches. No pressure. Just good people, good coffee, and focused time to build, learn, and connect. ## What this meetup is An open, welcoming space for coders, builders, designers, and curious minds. Bring your own project, homework, startup, side quest, experiment, or idea. Work at your own pace, meet other builders, ask questions, exchange ideas, or simply enjoy being productive around like-minded people. Expect: Focused building time Organic conversations Spontaneous debugging Knowledge sharing Genuine community This meetup is beginner-friendly, expert-respected, and ego-free. ## What this meetup is not ❌ A lecture ❌ A sales event ❌ A recruiting trap ❌ A 90-minute presentation ## How it works 1. Show up 2. Grab coffee ☕ 3. Open your laptop, notebook, or sketchpad 4. Work at your own pace 5. Chat when you want and focus when you need 6. Leave having made progress—or at least a new friend ## Who should attend Software engineers and data professionals Students and self-learners Founders and indie hackers Designers, tinkerers, and technologists Members of the Blockspace and Coffee&Code communities Anyone who enjoys building things with other humans Whether this is your first Coffee&Code, you are part of the Blockspace Community, or you have been attending since day one, you are welcome. This collaboration brings together two communities around a shared goal: creating a relaxed, supportive space where people can build, learn, and connect. Come for the code. Stay for the community. Leave caffeinated. ☕🚀

Join us for the 14th Philadelphia Hardware Meetup! Come join us to hear from our guest speakers as well as share what’s on your desk. We always have time for an open mic. This time, we're back at Delve's office on Arch Street. Hardware Meetups happen across 30+ cities monthly and help bring together different professionals to connect and meet each other. We will have a great set of featured speakers for the evening!: Dan Lykens, Electromechanical Engineer at Production Systems Automation. Dan is a multidisciplinary engineer and entrepreneur with over a decade of experience in electromechanical systems, PCB design, and product development. At PSA, he leads defense-focused R&D projects, specializing in rugged electronics. Dan combines deep technical proficiency in PCB design, CAD modeling, and advanced prototyping techniques. David Levine, Senior Solutions Engineer, Viam. Viam is a software platform for building, deploying, and managing robotics applications. Viam brings software engineering practices to robotics: version control, remote monitoring and diagnostics, staged rollouts, and a registry of modules and models you can build on. At Viam, David is one of the leaders of robotic solution design -- including hardware, electronics, safety systems, and supporting software -- for automation customers across various industries. Prior to joining Viam, David received his Ph.D. in Mechanical Engineering from UPenn in 2023 and B.S. in Mechanical Engineering from Cornell in 2017, and previously founded a robotics startup in the Philadelphia ecosystem, which was later supported by the Cornell Tech Runway Postdoctoral Fellowship. Daniel Marcq, Client Partner and Senior Director of Electrical & Software Engineering at Delve. Dan leads the development of complex hardware and connected systems from early strategy through commercialization. Since joining Delve in 2019, he has led multidisciplinary programs spanning electrical engineering, embedded systems, robotics, sensing, cont

## Claude Code vs. Codex: Loops, Graphs, and Harnesses This is a casual pair-programming meetup for developers experimenting with Claude Code, Codex, and agentic coding workflows. There is no formal presentation and no fixed curriculum. Bring a laptop, a repository, a side project, or a workflow you want to test. We will work in small groups, compare approaches, debug problems, and share what is working. Possible areas to explore include: Building iterative coding-agent loops Comparing Claude Code and Codex on the same task Designing graph-based agent workflows Creating reusable coding harnesses Managing context across large repositories Running tests and validating agent-generated changes Using sandboxes, permissions, and approval steps Coordinating subagents or parallel tasks Measuring latency, token usage, cost, and completion quality Debugging failed or incomplete agent runs You do not need to be an expert in either tool. This meetup is for people who want hands-on time to experiment, pair with other developers, and learn through building. Bring something you are working on, or join someone else’s project.

# 🤖 AI Agent Hackathon ## Two Days. Two Locations. One Hackathon. Join Coffee & Code Philadelphia for a hands-on, in-person hackathon focused on building, experimenting with, and shipping working AI-agent projects. The main Build Day takes place on September 20 at Pennovation Center. Winners will be announced during our Awards & Community Night on September 22 at Cesium. You can arrive with a team, meet collaborators at the event, build independently, or join without a finished project idea. ## 👤 Who Should Attend? This hackathon is for developers, engineers, technical builders, founders, researchers, students, and anyone interested in experimenting with AI-agent systems. Whether you already work with agent frameworks or are just beginning to explore them, the goal is to test ideas, learn from other builders, and leave with something working. You may participate: With an existing team By finding collaborators at the event As an independent builder Without a finished project idea ## 🧠 What You Can Build Projects may explore: Coding agents Multi-agent systems Tool use and automation Agent memory and context Evaluation and reliability AI safety and security Open-source agent frameworks Real-world agent applications Sponsor challenge tracks The Open Track / Bring Your Own Project ## 📅 Day 1 — Build Day Sunday, September 20 Pennovation Center 3401 Grays Ferry Avenue Philadelphia, PA 19146 ### Schedule 9:00–9:40 AM — Registration and check-in 10:00–10:15 AM — Opening ceremony 10:15–10:30 AM — Challenge track introductions 10:32–10:35 AM — Quirq 10:37–10:40 AM — The Code Registry 10:42–10:45 AM — GalaxyGate 10:47–10:50 AM — Human Standard 10:52–10:55 AM — Open Track / Bring Your Own Project 11:00 AM–6:00 PM — Hackathon build time ## 🏆 Day 2 — Awards & Community Night Tuesday, September 22 Cesium 601 Walnut Street, Suite 250S Philadelphia, PA 19106 ### Schedule 6:00 PM — Arrival and check-in 6:15–7:00 PM — Featured speakers and lightning talks
