ENGINEERING EXCELLENCE STARTS ON EDGE

Summary from the TLDR newsletter

The best engineering teams develop their own tools while running production code on edge, where progress is made. When programmers are able to directly influence the tools they're working with, they're likely to do so, which makes them learn more. However, this requires being able to immediately use the improvements or bug fixes they helped devise - it doesn't work if they have to sit and wait for the next release. Bug-free frameworks and libraries take work, but the reward is increased engineering excellence.
