# The fix is based on installing an older version of libsane and libsane-extras
# For more info, see [1] and [2]

# To apply the fix, copy/paste the following in a terminal:

#   . Uninstall libsane + libsane-extras
sudo apt-get remove libsane libsane-extras

# How to add user into group, and make changes take effect *without logout/login*: the *newgrp* command 
#
# Do note that this method will only update the groups, in the current shell session (and its child-processes).
# New shell sessions will not have the groups updated - either use this method to update the groups in each shell 
# session, or logout/login to make the group update permanent by default 
#
# In short: 
#     $ sudo adduser user_x my_grp
#     $ newgrp my_grp && newgrp

require 'socket'
require 'spoon'

# I made this code to experiment with 2 things:
#   1) Use the 'spoon' gem and Spoon.spawnp as a poor-man-substitute of a normal fork
#   2) pass a file-descriptor over unix-sockets, from a parent process to a child process
#
#   Jruby cannot .fork() as MRI Ruby... it seems the alternative is 'spoon' gem and its 
#   spawn/spawnp methods. 
#   Fork is not the same as spawning: basically fork will copy to a child process all
