Katas (å½¢) are practiced in martial arts as a way to memorize and perfect the movements being executed. Let's try the same with Go code.
I've been learning to program in Go. I work in the sysadmin/devops and security areas so I don't get to program every day. But I still want to keep my coding skills fresh. Maybe even improve them. I use gokatas as one of the ways to achieve this.
The approach is pretty low-tech. Go katas is basically a list of packages and commands that you should be rewriting from scratch or partially. There's a command to show katas and your progress:
$ go run cmd/katas.go -d 7 -l beginner

It's important to practice regularly, to create a habit. Set a goal that you can meet, e.g. 45 minutes every day before work. At first it's fine even if you only read through one of the beginner level katas.
After some time it will require much less will power and you will become more familiar with the code. If you feel comfortable enough with a kata, stop practicing it (for some time) and pick up one that interests you and is slightly beyond your current ability.

Fork and then clone the repo:
git clone git@github.com:<you>/gokatas.git. -
Start practicing:
cd gokatas
> katas.md # if you are not me :-)
