We’re at #KubeCon, where reliability runs deep (and so does our love for perfectly cromulent coffee and waffles!)

That’s why we’re teaming up with our friends at @augmentcode.com for a breakfast that celebrates both on Wednesday morning at Waffle House!

Learned a lesson about @flox.dev today. The more stuff you have in a default environment the more likely it is that you’ll accidentally leave something out of a project environment because it’s already available. Won’t be obvious until someone else tries to use the project without your default env

Flox brings the power of #Nix to teams:

- Familiar commands
- Cross-platform reproducibility
- Declarative manifests (TOML-based) that are readable, versionable, and easy to share.
- Team-ready workflows: push, pull, build, publish — just like git.

Flox = AI-friendly dev environments

Flox is a cross-platform, cross-language package and environment manager built on open-source #Nix, but wrapped in a workflow that feels natural for both humans and agents.
