daily learnings

#go

• layout packages by what they do, not by their abstract type
• use channels sparingly. write synchronous methods and allow the caller to make it async
• append modifies the underlying slice, you'll only make this mistake once
• define interfaces where you use them
• make([]int, 5) has a length and capacity of 5. ([]int, 0,5) has a length of 0 and capacity of 5.
  append() will only do what you want with the latter
• don't use init()
• TFBO (test, fix, benchmark, optimise)

#git

• git commit --fixup=<COMMITSH>
git rebase origin/main --autosquash
