The original discussion on copyrighting evolved from a post by brucer in another thread.
Apologies to bruce if my answer drew attention away from his discussion (sometimes I can be frivolous in my comments and I intended no offence). To set the record straight. bruce originally said: >I think that the larger question is protection of AFL's. >There are two reasons for >protecting the source - one obvious and one not so obvious - >1. To charge for the code and for the intellectual property. The >market will decide if the price is reasonable or not. >2. To protect the source. Many times others will mod the source and >then tie up author's time with questions about how the original >software worked OR why the modified software doesn't work. I assumed you were referring to 'copyrighting AFL' but that might not necessarily be what you were interested in. You went on to say: >Certainly code can be placed in a DLL to hide it. It >is also fairly easy to protect it. It is just a pain and a >productivity hit to convert AFL to a DLL just to protect it. >Protection tends to fall into two categories - >1. Wrappers for EXE's and DLL's that implement keyed protection for >existing binaries and require no changes. The protection may or may >not be machine unique. For example, ASPROTECT >2. Embedded protection calls that require changes to the app. Several >libraries available - some open such as ACTIVELOCK >Anyway, I'd be interested in others thoughts on this issue. Progster commented on the same subject: >Since DLL writing is (almost) platform agnostic, DLL writers in the >trading area will have a tendency to code for platforms that provide >built-in support for locking a DLL to a customer or software ID. >I would predict that such "commercializing" integration features >would >result in a distinct increase in the number of commercial DLLs >available for AB. --- In [email protected], "brian_z111" <brian_z...@...> wrote: > > 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" <groups@> > 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" <groups@> > > To: <[email protected]> > > Sent: Saturday, December 20, 2008 11:15 AM > > Subject: Re: [amibroker] COPYRIGHT > > > > > > > Hello, > > > > > > You guys mix up things.
