AFL protection - Protectionism vs Free distribution We have seen many examples. Linix is a freely distributed OS, and much of its growth is attributed free distribution of source code. Linix's core developers didn't have the budget or man power to grow its market without tapping into the overall community for free contributions. Microsoft on the other hand, strongly believes in its inhouse developed edge and tried to guard it as much as possible, by keeping it as secret as the laws allow it.
Open source is always the fastest way to spread the use of a software product. Take a look in the AFL library, I would argue that most afls posted are small, rudimentary and often specific their its purposes, their utility relies on the fact that they can be easily customised, and the open source serves as documentation on what needs to be done. They are completely open to the adopters imagination. When AFL becomes encrypted, or protected, they become canned, and has to be used as it is. For any canned product to be out in the public, regardless whether it is free of charge or not, it has to cater to all or most of its users need, and not just the writers. There is a huge effort on the writers part to analyse the needs of the type of users that he wants to target. They called that system analysis in software development. Then he has to develop it, and then carry out all sort of tests, more than ever. Because now protected, no users can contributed to any debugging whatever. After all that is done, the writer has to thoroughly document with user guide, reference guide, etc. Because no one will know how to use it otherwise. With the exception of the few who are selling their ware, most will not want to go through that trouble and shy away from contributing. By the way, any encrypted afl will be cracked within day, if not hours. We have encrypted vbscript and jscript today, they are neither secured or popular. If answering a few question for curious users on how to modify author's code is tieing up the author's time. Then canning AFL is a sure way to killing all his time! If someone really wants to protect their intellectual property and has deemed it worth protecting, they should convert their ideas into dlls or have them converted by someone. Dll fullfills the needs of protection totally and is far more secured. without forcing a new barrier onto the masses. In my view, afl protectionsim is aiming at guarding the fortune of the few, because there will be very few who will wants to use it. the majority will be just happy to share the ideas, no matter how small, freely and easily, or not at all. If AFl protectionism becomes reality, Tim will soon be asking Why are there so few AFLs. LOL! In another twisted way, I have answered once more why there are so few dll. --- In [email protected], "bruce1r" <[EMAIL PROTECTED]> wrote: > > Progster - > > Your response addressed DLL's and made good points about intellectual > property, but IMO you might have missed a point and been a little off > the larger target. > > I think that the larger question is protection of AFL's.
