Who Killed the Build? 💀

A Halloween DevTools Murder Mystery with Flox

The build is dead. The cause? Unknown.

Join AI Valley and Flox for a Halloween devtools night where you’ll investigate what went wrong, follow the clues, and figure out who (or what) killed the build.

Instead of a traditional product demo, Flox will take us through an interactive investigation of a broken development environment. Along the way, you’ll uncover suspicious dependencies, environment issues, and other clues before making your final guess.

🔎 Investigate the crime scene
💻 See Flox in action
🕵️ Follow the clues and solve the mystery
👻 Hear real developer horror stories
🎃 Enjoy Halloween food, drinks, and networking

Costumes are encouraged. Production incidents are not.

Flox is a developer tool that creates reproducible, hash-pinned software environments across laptops, CI pipelines, and production. It eliminates environment drift by using a single configuration file to lock exact software versions everywhere. Flox is powered by the Nix package manager, but simplifies the experience so users do not have to write Nix code directly.

AI Valley is a community rooted in supporting exceptional first generation builders, founders, and creators. We curate environments where ambitious people meet collaborators, mentors, and opportunities through hackathons, workshops, and intimate gatherings across AI, tech, and the arts. If you care about who you build with as much as what you build, this is your place.
