The OP is surprised why you can't find gifts that do this. The answer is simple: it's patented. No one in the USA is safe to produce this kind of effect without being sued, and the major photo publishers must be quite aware of this patent status and are not willing to pay the extra cost for the feature.
Living in Indiana, I can say that the switch was a mess for a lot of clueless folk in our (Computing) department. One example was shared Outlook schedules. If one person had applied the patch to the time zone file and another had not, appointments would appear to be the wrong times. Instead of thinking, "Oh, my computer hasn't been fixed for the new DST rules," they would think, "Oh, Outlook is a piece of crap. I'll go and fix all the times." And chaos ensues.
I can only imagine what the rest of the country will experience with people in homes and businesses with even less of a clue than the people I'm referring to above. I don't think things will come down in flames or anything, but there will be a TON of frustrated users trying to get their PCs/PDAs/thermostats/etc. to do the right thing.
I'm shocked to see how many people are complaining about this issue. To me, the real test of your coding skills should be done with homework assignments and projects. They show that you understand the problem and how to solve it using the paradigm given.
As others have said, the role of exams is to test the CS concepts being taught: algorithms, methodologies and problem solving skills. It's important to be able to demonstrate you know what a linked list is and when it should be used instead of an array, but that doesn't require a significant amount of coding in the test.
It seems to me that this whole subject is full of irony in the sense that one of Napster's central legal defenses to the music industry is that it cannot identify copyrighted music. How would that be any different from identifing Nazi music?
Forget any deep philosophic reasons for not doing this--Napster won't do it because it will demonstrate RIAA is right.
I use printf(), also, but it isn't sufficient for multi-threaded programs because of race and deadlock conditions. The printf() can change the timing enough to alter remove the race or deadlock. A nice debugger would help in those cases to tell where each thread is. Unfortunately, I haven't used one. In fact, I was in this situation earlier this week on a machine without any working debuggers. Reading through the code reasoning what was happening was the only method open to me. I love gdb and use printf() all the time, but in the end, understanding your code thoroughly is the only way you will be able to find and fix errors.
