It's Hacktober 👻 That means it's time for another spooooky celebration of open source software with the PHL Code Club and a few other communities at Indy Hall. How it works We are still ironing out the details but here is the overview: Over the course of October submit 3 high quality pull/merge requests to open source projects of your choosingWe will have a fun prize for anyone who completes all 3! High quality does not mean large or complex, it just means useful. Please don't spam project maintainers with junk. This is specifically an LLM/Generative AI free event. The goal is not only to improve the software you love, but also improve your skills and knowledge while you're at it. Go to https://hacktoberfest.phlcode.club and share projects you are interested in working on!This is a great place to find inspiration for projects or try to recruit others to work on a project you find interesting We will be hosting some online "hack sessions" for people to body double and pair program. Keep an eye on the Luma for these.Also come to the Indy Hall Neighborhood Coworking Nights to hack together in person!! Come share what you worked on at the party on the 26th!Costumes are highly encouraged. Go ahead and RSVP now, plan out your costume, and keep an eye out for updates both as blasts from Luma or in our Discord. So excited to have another year of our fun with you all. May you avoid the scariest thing of all - MERGE CONFLICTS O.O Schedule 🗓️ 6-6:30pmDoors open, snacking and socializing 6:30-8pmShare what you worked on!

# ☕ 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. ☕🚀

## 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. Hosted by CODE. CODE Website: https://www.codephilly.com Instagram: https://www.instagram.com/coffeecodephilly Discord: https://discord.gg/2ad8NmvC2

## Claude Code Saturdays 🤖💻 A weekly hands-on meetup for builders using Claude to write, refactor, and reason about code.

``` Join Eric Manganaro and Justin DiClemente at Pennovation Center for Reverse Engineer Anything (REA), with two talks on Rust and CNC control. Eric Manganaro: Building a library of ideas with Rust Eric will show how he uses Rust to capture ideas from programs he reverse engineers. His REA system stores recurring themes and architectural patterns so he can reuse them in new projects, in Rust or other languages. Justin DiClemente: REA for industrial automation Justin will show how REA applies to CNC control. A planned demo will run actual controller firmware against a simulated FPGA and a virtual CNC mill, tracing software commands through to machine motion. Time permitting, we’ll also look at proprietary 3D printer software, with Bambu Lab as a possible example. Pennovation Center 3401 Grays Ferry Avenue, Philadelphia, PA ```
