require 'json'
require 'faraday'
conn = Faraday.new(:url => 'http://localhost:3000') do |faraday|

end

while true do
  grid = life[grid, size]

  wire_grid = grid.map { |value| value ? 1 : 0 }.to_enum(:each_slice, size).to_a

  conn.post do |req|
    req.url '/06e7798a-34a3-49a0-a6b2-360026027907'
    req.headers['Content-Type'] = 'application/json'
    req.body = JSON.generate wire_grid
  end

  sleep 0.2
end

just FYI in ruby you can loop {} instead of while true {}
