Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Error: Failed to update tap: caskroom/versions


brew untap caskroom/cask
brew update
brew cleanup --force -s
rm -rf "$(brew --cache)"
brew tap caskroom/cask
This removed what I believe is a unnecessary single quote in the rm command and a period that was probably not intended after the last command
Also in my case, I needed to add sudo for the remove command
