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

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...

Benefits: • Perfect reproducibility across all devs and CI • OS independence (Fedora, Arch, Ubuntu/Debian, NixOS) • Lightning-fast caching • Simple activation (just cd into project) • Native performance (no Docker overhead)
