Golang — Understanding channel, buffer, blocking, deadlock and happy groutines.

I was so confused to understand behaviior of Golang channels, buffer, blocking, deadlocking and groutines.

I read Go by Example topics.

Install Docker CE and nftables:

Standard escape codes are prefixed with Escape:

	### CONTAINERS ###
	docker stop $(docker ps -a -q) #stop ALL containers
	docker rm -f $(docker ps -a -q) # remove ALL containers
	docker rm -f $(sudo docker ps --before="container_id_here" -q) # can also filter

	# exec into container

	针对小容量mac book扩容的解决方案

	需要购买：
	1.nvme硬盘盒
	2.大容量 nvme固态硬盘（推荐500G以上容量）

	推荐下面这种侧插式nvme硬盘盒，完美匹配mac book，速度是10Gb/s,而且关机也不用取下。
	缺点是要占用一边两个雷电接口，硬盘盒自带一个充电接口，
	算下来其实还好，不充电的情况下，多占了一个雷电接口。
