#!/usr/bin/env ruby
# returns a 16 character password
require 'securerandom'
# puts SecureRandom.hex(8)  #returns all lowercase

# the result may contain A-Z, a-z, 0-9, “-” and “_”. “=” is also used if padding is true.
# puts SecureRandom.urlsafe_base64
pw = SecureRandom.hex(8)
# uppercase the first contiguous block of non-digits
puts pw.sub(/(\D+)/) { |m| m.upcase() }

# In the block form, the current match string is passed in as a parameter, and
# variables such as $1, $2, $`, $&, and $' will be set appropriately. The
# value returned by the block will be substituted for the match on each call.

ASA notes - faramt android crashing upon initial run on test device (6.0.1)

faramt android crashing upon initial run on test device (6.0.1)

appears to have something to do with downloading the zip of figs.

fix:
apk file size limit on google play increased to 100MB:
http://android-developers.blogspot.com/2015/09/support-for-100mb-apks-on-google-play.html

if we include the ac figs we're still within this limit.
so do that.
