setting up mac keyboards key repeat

with a new laptop means that you need to make all the changes to all the things. One of the annoyances that I had was the key repeat. Yes you can change this in the gui but why would I want to do it there when I can do it in the terminal instead…

$ defaults write -g InitialKeyRepeat -int 15
$ defaults write -g KeyRepeat -int 2

  t1 = time.time()
  return (time.time() - t1) * 1000.0

  delay = float(pinger_urllib(m))
  print '%-30s %5.0f [ms]' % (m, delay)
