FDL Math Textbooks?
PyTHON71 asks: "I'm working through Schaum's Outlines of College Algebra. So far, in chapter 17 (conic sections), I've found 6 errors! Since I can spot them and correct them, I'm not worried about myself. But without math, you can't hack, and if young hackers are getting hung up on stupid math mistakes made by textbook authors... well, it's obviously a case for FDL textbooks. Are any textbooks being produced under the FDL?"
I'd never heard of it until this post, but the context indicates "F(ree) D(ocumentation) L(icense)", which google confirms. Some acronyms are so obvious that I can forgive the editors for assuming their audience either already knows, or can look them up themselves. If a newspaper used an obscure term, name, or acronym without defining it, that's a real booboo, as the reader is unable to comprehend the article without a major context change. However, this isn't a dead tree document. If you're reading it, you also have instant access to other references. That said, I too am troubled by the dupes. I'm perfectly capable of recognizing them, and combining the useful comments from each, but I'd expect the editors to regularly skim the content they are managing. It doesn't mean they're not doing a good job, but such slap-in-the-face obvious dumb mistakes as dupes and misspellings keep bringing up questions. It's like a big tough marine with a lisp. There's that constant cognitive dissonance between the fact that he is tough and the other fact that he sounds like a sissy. The editors are all smart and work hard. CT is making money on the web without pr0n, for heaven's sake! ...But, they keep doing things that make them sound stupid and lazy(in the negative sense).
Anyway, cut them some slack for overestimating you.
