Thanks Tomasz, That adds further clarification to the good opinion already posted by Progster, Barry and Dennis (in another thread).
The points made in 'your' links tend to support my hunch that: - a book can be copyrighted but not the code that it contains - people are free to restate any trading idea, using AFL, since AFL is a unique language and hence any expression of a trading idea would automatically be unique (especially if the idea has been translated into psuedocode before posting it to a forum for coding into AFL). The only slight concern I have is that dissension, or confusion, may be created by people quoting AFL code that has been published in a copyrighted environment. I can't help wondering if AFL could me made an open source language but that is possibly some silly romantic notion I have. My overall interest in the subject is because I feel that copyrighted material, may in many cases, hold back our progress (our being mankind), including our economic progress ..... one of your links provides a very good example of the wasted resources that MS have put into copyrighting www. and .com where they are used on a cell phone. Obviously open source software is an entirely knew phenomenon suited for an entirely new breed of humanity. brian_z --- In [email protected], "Tomasz Janeczko" <gro...@...> wrote: > > I may add that mathematical ideas (including algorithms) should never have any patents granted > http://www.lbl.gov/Workplace/patent/app2.html > and this rule is usually followed, however > US Patent office has unfortuntally has granted several ridiculous patents. > http://freedomforip.org/category/patent/ > > Best regards, > Tomasz Janeczko > amibroker.com > ----- Original Message ----- > From: "Tomasz Janeczko" <gro...@...> > To: <[email protected]> > Sent: Saturday, December 20, 2008 11:15 AM > Subject: Re: [amibroker] COPYRIGHT > > > > Hello, > > > > You guys mix up things.
