Re: Nobody is perfect..including Dann and Bryan

The fact is it is based on closed source and that constitutes theft. It is theft, in so far the Rybka license forbids this kind of reverse engineering. (Which I suppose it does.) Otherwise it would not be a (legally) closed source. It is, however, up to Vas to act against this. If he condones it by...

Re: Nobody is perfect..except Dann and Bryan

In the USA it is rare for the loser to have to pay for the trial. It could happen, but I wouldn't count on it. Well, I am not a U.S. citizen, but I would dare to count on it that in any civilized society you would be made to pay if you are harassing people by suing them without any legal basis what...

Re: Nobody is perfect....

Unfortunately, it makes less sense than ever. Let me tell you how copyright law works: Authors are allowed to specify conditions what people can do with copies they make of their (i.e. the author's) work. That can range from "nothing" to an obligation to "make them publically available under the sam...

Re: Equal Treatment 2

I don't see that as a burdensome choice at all. You don't have to believe anyone. Facts are facts, and can be independently verified. If Rybka contains Fruit code, comparing the assembly code of the two produced by the same compiler (after verifying that Rybka doesn't use any tricks to encrypt its c...

Re: Nobody is perfect....

It is clearly not a copy of Fruit, or Dan and Bryan would have recognized it as such. They are our judges, and I am convinced that if this case were ever to come to court a professional judge would come with the same verdict. If only because he would consult similar experts as Dan and Bryan. The cod...

Re: Nobody is perfect....

Well, it seems to me the burden of proof is on you, since what you claim defies logic. Show me one court decision where two things that had zero text in common were ruled to be a copy under copyright law...

Re: Nobody is perfect....

Why should I ask the FSF? Their opinion is worth zilch! They are subject to the law, and if they would make claims that are counter to the law, the claims are void. No matter how often or loud they make them, how wide they would spread them or how eager they would be to tell me about them... In part...

Re: Nobody is perfect....

No, once it is GPL, it will be always GPL. You can change 100% of the code, its still GPL. This is total nonsense. GPL is a copyright condition. The law specifies what is considered a copy, and what not. Nowhere in the world would something that is 100% different be considered a copy. So it is irre...

Re: Strelka and source code experts

I don't see why we should harass the 'source-code experts', or even doubt their judgement. Strelka was not a cloning job, the source code was largely original. That verdict stands. That it was largely inspired by Fruit, doesn't make it a clone. Using partially the same data structures does not make ...

Re: Silly transposition table question...

I think the "industry standard" is to store some time stamp in your hash entry, so that you can see how many searches ago it was made, and then use depth minus age as a basis to make the replacement decision. So there is no explicit pass through the hash table, but the cleanup is done as a side effe...
