I had a fortune to interview David Hagege, the CTO of Agricultural Tech Startup ListenField. He has succesfully introduced Nix and NixOS to his organization and describes his journey in thorough detail in this interview.
I want to tell you about a development technique called "Snippet-driven Development". I have successfully implemented it at one of my previous workplaces, and brought it to all the companies at which I have worked in a managerial position ever since. It can help you move faster and get feedback sooner, which is always valuable.
