GOING FAST SLOWLY

Summary from the TLDR Web Dev newsletter

Despite the Varnish cache project having over 150,000 lines of code, the average productivity of the two main developers of the project over ten years is estimated at only 5 lines per hour. This low productivity is a result of prioritizing quality and correctness over speed, as shown by extensive testing, meticulous code style, and a focus on avoiding errors. The lack of user complaints about Varnish suggests that this approach has successfully achieved its goal of producing high-quality software.
