Page 24:
Disregard the statement, "(T stands for a true statement, and F stands for false)" and the associated footnote. Equations that follow this paragraph should read (changes in bolded):

NOT a <=> NAND(a, a)
AND(a, b) <=> NOT NAND(a, b) <=> NAND(NAND(a, b), NAND(a, b))
OR(a, b) <=> NAND(NOT a, NOT b) <=> NAND(NAND(a, a), NAND(b, b))

and

NOT a <=> NOR(a,a)
OR(a, b) <=> NOT NOR(a, b) <=> NOR(NOR(a, b), NOR(a, b))
AND(a, b) <=> NOR(NOT a, NOT b) <=> NOR(NOR(a, a), NOR(b, b))

Please note that in the second sequence of equations, lines beginning with AND and OR were swapped to match the previous set, so that the ordering of both sequences is NOT-AND-OR.

Page 31:
The symbol used on Figure 2-4 for rightmost gate ("OR") is actually a graphical symbol of "XOR". The picture should be updated to remove the curved line on the left side of that gate, to match "OR" shown on Figure 2-2.

Page 32:
The second line reads "(see Figure 2-4)". This should be "(see Figure 2-4, leftmost portion)"

Page 171:
The mention of "Joe Steward" and in the index should actually be "Joe Stewart."

Page 148:
"Point of Presence" should be "Post Office Protocol version 3."

Page 116:
The number "3241036664" should actually be "3279225659."

Page 169:
The author of ISNProber is Tom Vandepoel, not Toni.

Page 228:
In section "Nibbling at the CPU," references to "non-polynomial" problems should be "non-deterministic polynomial."
