I've really been enjoying the `devenv` tools for `nix` environments. I've also made it so that AI agents for projects by default must use the `devenv` environment. It's not hardened or anything, but it is nice to be able to destroy environments safely on demand.

We are happy to inform you that your proposal “What if GitHub Actions was local-first and built using Nix?” to NixCon 2025 has been accepted.
Now that I finally started using #devenv instead of flakes. I get it. It's way nicer that way.
Stop fighting your ROS 2 environment! Tired of "works on my machine" nightmares, Ubuntu version lock-in, and Docker workarounds? Here's how to build faster, reproducibly, anywhere using Nix. Read my blog post: mykhailo.link/ros-devenv
Stop Fighting Your ROS 2 Environment: Build Faster, Reproducibly, Anywhere
You're a ROS developer. You love building cool robot applications, tackling complex navigation challenges, and making hardware *do things*. What you probably *don't* love is the endless cycle of dependency conflicts, the "works on my mac...
