Keybase proof

I hereby claim:

• I am josemmo on github.
• I am josemmo (https://keybase.io/josemmo) on keybase.
• I have a public key whose fingerprint is C682 DE96 BC11 DA37 F599 C409 B66A A458 1742 36B2

To claim this, I am signing this object:

var fp_sources = {};

// Ahora ya podemos guardar los datos que hemos obtenido

  appCodeName: navigator.appCodeName,
