                Automatically launch Cuphead (from Steam) on a Mac when a Nimbus Bluetooth game controller is connected.

    The only game I play on the Mac Mini connected to our TV is Cuphead.
I wanted the game to launch automatically when I turn on one of our Nimbus game controllers, which connect via Bluetooth.
This is how:

Save the .scpt file below as e.g. ~/Library/Scripts/LaunchCupheadIfControllerIsConnected.scpt

In the .scpt, change "Nimbus" if your Bluetooth game controllers have some other name.


Save the .plist below as e.g. ~/Library/LaunchAgents/henrik.launch_cuphead_if_controller_is_connected.plist

In the .plist, change media to whatever your username is.

    Written down for the benefit of googlers, since I've tried to figure it out to make it at home.
This is my best guess from overhearing things and glancing behind the bar:

One part Zymurgorium "Realm of the Unicorn" gin
One part Funkin Pro bubblegum syrup
Add lemonade
Add ice and strawberries cut in half

I've tried the Imaginaria gin and I've tried the Monin bubblegum syrup, but they don't taste the same.

## spanish_organization_number.rb
# By "organization number" we mean an organization NIF (Spanish tax identification number). We don't mean personal NIFs such as DNI/NIE (see `SpanishIdentityNumber` for that).
#
# This class also supports personal NIFs starting with the letters K, L or M, though it's inaccurate to call these "organization numbers". More about these: https://translate.google.co.uk/translate?sl=auto&tl=en&u=https%3A%2F%2Fes.wikipedia.org%2Fwiki%2FN%25C3%25BAmero_de_identificaci%25C3%25B3n_fiscal
#
# It's easier to support them than not to, and means that any such users can provide this number, even though it's represented a bit inaccurately in our system. They're likely to be very rare. Feel free to think up a way to represent it more accurately. (Renaming `spanish_organization_number` to something like `non_dni_or_nie_spanish_tax_identification_number`?)

class SpanishOrganizationNumber
  # NIFs do not have the letter prefixes "I" and "O" since those can be confused for the digits "1" and "0".
  # Don't know why "T" is not a p

## 1-exhaustive_case_exact_match.rb
# This replaces conditions like: `case …; when …; when …; else raise "Nothing matched!"` if an exact match is all you need.

def cond(input, hash)
  hash.fetch(input) { raise "No branch for #{input.inspect}!" }.call
end

input = :good
cond(input,
  good: -> { puts "So good!" },
  bad: -> { puts "So bad!" },

# In order for this to work, first go to the TV "General" settings and turn on "Mobile TV On".

# Change this to the actual value.
# First find the TV IP, e.g. from your router's list of connected devices.
# Then run "arp -a" on a computer and you'll see the MAC by its IP.
# Maybe you need to "ssh <the ip>" before it will turn up in arp. Not sure.
