I just saw the delightful high-quality site on core computer algorithms Hacker’s Delight. I was startled by the following notice about the corresponding book:
“After the first printing, an errata file was started. The publisher did not incorporate this into the second printing. For the third printing, he made all the corrections known up to that point in time. For the fourth and fifth printings, the publisher subcontracted the production work, and accidentally gave the subcontractor the files for the first printing. The sixth printing corrects all the errors known up to when it was printed (November 2006). Therefore, the best copy to obtain is the sixth printing, and the second best is the third printing.”
Good grief. This is the kind of thing that makes airplanes fall out of the sky — or my bank say “oops.” As an engineer, I have long been aware of how much stuff out there is truly not designed, transcribed, or built correctly, but this little example gives a nice compact summary to my unvoiced horrified sputtering. I wonder if more direct and immediate Internet technology (like Wikipedia and maybe Sophie) will help.
