Printed	Page 94 Hack #24	The first part of paragraph 3 should read, 'Limits can be broken (see "Record setting," described earlier) -- for example'. Note the corrected punctuation and that this paragraph now forms a single sentence. This corrects the spelling of the word MANUAL in the hack's hidden acrostic.	scottd_oreilly	Feb 12, 2009	Nov 01, 2008
Printed	Page 158 Hack #41 Paragraphs 3-4 should now read:	Could Bart even theoretically pick all those grapes in less than three months? Let's say Bart picks one grape per second, which seems plausible (he certainly doesn't manage 10 in a second, but he can do more than one every 10 seconds). At this pace, he'd manage 3,600 in an hour. Let's round that down to allow time to move between bushes, empty the container, and so on, but to compensate, we'll have him work 20 hours a day. So, Bart manages 60,000 (20 ? 3,000) grapes a day. If we round that to 50,000 to get a nice factor of 10 [Hack #36], we see it will take 20 days (1,000,000 / 50,000, which is the same as 1,000 / 50) to harvest 1,000,000 grapes. This is somewhat less than three months (which is about 3 ? 30 = 90 days). So, an estimate of three months seems somewhat reasonable even though it was intended as humorous exaggeration -- but there were a lot of guesses in there. If this were important, it would be worth doing a more careful analysis of things, such as Bart's grape-picking speed.	scottd_oreilly	Feb 12, 2009	Nov 01, 2008
Printed	Page 167 Hack #43, Paragraphs 3-4 should now read:	To get the century-item for any Gregorian year up to 9999, take the first two digits of the year, cast out fours, subtract the result from 3, and multiply the difference by 2. Thus, for the year 2008: 20 mod 4 = 0 3 - 0 = 3 3 ? 2 = 6	scottd_oreilly	Feb 12, 2009	Nov 01, 2008
Printed	Page 183 Hack #47	Last paragraph should read: Remember, a _dominant strategy_ is a plan that's better than all the other plans that you can choose, no matter what your opponents do. In this scenario, consider a row where P consistently beats F. If there are no other rows with a better outcome, it's a dominant strategy for P to choose that row. The same would go for F and a winning column.	scottd_oreilly	Feb 12, 2009	Nov 01, 2008
