I would like to recommend two blogs. The authors maintain high standard of writing contents. They pick up not-easy topics and deliver them well. For those who are interested in go and docker/k8s, I recommend you to have a quick read.
The first one is Quasilyte blog. The author’s
topic is go compiler. Last November, I was trying to solve a bug in cmd/compile,
I have figure out the SSA format in a few days. Although my solution cannot
universally remove inline SSA marker, I still learn a lot.
But later I encountered with this blog, and I had wished I found it earlier.
The author illustrates the SSA of go in a very clear way: details, examples and
his understanding. Later he’s post on gogrep is also a good piece. Anyone
who wants to get into this world, just go and read it.
The other one is iximiuz. Both authors are writing in English and the original posts are in Russian. This author gives great overview from 5,000 ft high to 3 inch low on docker and orchestrations. I learn PTY, docker container layer, and the orchestration system.
