Nearly there now? How are you doing? Is it fiendish enough? Let's first answer yesterday's questions:
11. 128 bits. You would have known this at once, of course, because you carefully read our 22 December article about the introduction of IPv6.
12. Ted Nelson. Though quite a few others have tried to claim the title (including, rather laughably, BT at one stage which reckoned it had patented hyperlinks; it launched a series of lawsuits that everyone else knew would founder, which they duly did), he's definitely its father.
And now, today's questions.
13) Software released under the GNU Public License is free (as in free speech, not free beer) to redistribute and use, but carries certain restrictions. What is this concept called?
14) What is the term for a secret that a programmer has put in a computer program?
