The safe version of the second command you have is:
  find /home/username/ -xdev -print0 | xargs -0 chmod o-rwx

"-print0" causes find to print the lines with a NUL character (ASCII 0)
as the file separator, instead of the usual newline.  NUL is one of the
small list of characters that cannot appear in a Unix filename.

"-0" causes xargs to split on NULs, instead of spaces.
