Change the binary code to print out "FOSS ROXORS!" instead of "Hello World!". Spend no more than half a day on this exercise.

This is actually a tricky exercise, and it could take you a fair bit of time. We included it here because you might be curious and want to go poking around in the binary. Under most flavors of Linux you should be able to find or install a program called hexedit. To get you started, you use TAB to switch from hex to ASCII, / to search, and F2 to save your changes. You can read the rest of the documentation for hexedit by reading the manpage, which you can get to by typing man hexedit on the command line, or pressing F1 while running hexedit.
