A Rationale for Using Coroutines in Go — Many of the initial reactions to this suggestion by Russ Cox to introduce coroutines to Go were negative, with folks instead preferring Go’s existing channels based approach for the problems coroutines can solve. Nonetheless, there are some interesting and specific use cases for coroutines in Go, such as when iterating over generic collections, and Russ tries to convince us of their merit here. Luckily, it's all possible "without language changes".

Analyzing Go Build Times — Go’s compiler is pretty quick, but John was curious was what factors affect compile times. In this article he used the 350,000 lines of the Istio project to put Go through its paces, try out some ideas, and ultimately came up with some tips.
