- OK, (1) suppose someone posts some code to the net w/o a copyright
- notice. Can I use it, or is there an implicit copyright that says
- "no"? If the latter, then I may be better off if I don't read
- net articles that contain code.
-
- (2) Suppose I find out about an algorithm by reading a textbook.
- How much does my implementation have to differ from the one in
- the book? Should I stay away from textbooks that give code and
- look for ones that give only informal or mathematical descriptions?
-
- Now, from "form of expression" it sounds like translation to a
- different programming language might suffice, but I doubt it really
- does.
-
- In short, does the common practice of finding out how to do something
- by reading books, papers, and net articles violate copyrights?

- PS I've directed followups to misc.int-property. Is that ok?
