Direct copy of Project Euler problems
This is the second Project Euler problem which is proposed as Rosetta Task without any change. Of course, there is no copyright on this problems but are we going to take all Project Euler problems to feed Rosetta Code? Moreover, this is not fair for Project Euler as we are now spoiling its problems by providing solutions. I suggest removing this task and the task Permuted_multiples. --lscrd (talk) 16:19, 5 September 2021 (UTC)
- I agree. If I hadn't gotten so much push back before when I tried to moderate added draft tasks this would already be gone. --Thundergnat (talk) 17:39, 5 September 2021 (UTC)
- I also agree that Calmosoft should be asked to desist from posting any more unmodified Project Euler tasks or risk having them deleted. However, I'd let the ones that have already been posted stand as a lot of thought has been put into finding optimal solutions by various contributors. --PureFox (talk) 17:54, 5 September 2021 (UTC)
- +1 however Permuted_multiples potentially has some merit, unlike this task and especially Special_pythagorean_triplet, which is entirely about devising an efficient algorithm and nothing at all to do with the differences between programming languages. Mind you the same could be said for the older Sum_multiples_of_3_and_5. I certainly don't envy anyone trying to police this. One thing Calmosoft is either unwilling or incapable of comprehending is that projecteuler plainly says "don't", though it is more debateable as to who is making a more of a fool of themselves: him for posting these tasks in the first place, or those of us that far too eagerly start submitting solutions, and I am not entirely innocent there. --Pete Lomax (talk) 18:08, 5 September 2021 (UTC)
- Problem is, we all provide solutions to these tasks and then say we want to delete them - maybe if we just ignored the tasks we don't like, didn't post solutions and waited for Thundergnat to rule on them, there might be more justification for deleting them. Perhaps we could flag then as "Under Review - post solutions at your own risk" or something ?
- RC has a Category:Simple for easier programming tasks - the Sum_multiples_of_3_and_5 could fall into that category. I like that task as a small amount of thought can yield a better solution than the obvious one.
- What do you particularly dislike about Special_pythagorean_triplet (a task you have provided two solutions for) ? Other than several of the solution authors haven't read the task description and/or have neglected to calculate a * b * c, I have no problem with it. I for one, put not inconsiderable thought and effort into it, as I imagine Nigel, yourself and several other people did too. For that reason alone I think it should stand.
- However, I must agree that RC should not just be a collection of tasks "find primes with property X" and "solve Project Euler Problem Y" and perhaps we should draw the line here.
- The use of the task test verbatim from Project Euler worried me considerably, however I believe their license allows it - after re-reading the license page several times, I came to the concluson that the bit that says it can't be re-published is refering to everything else except the problem itself. I'm not a lawyer though, so I could be wrong... Whether their license means the task page as a whole is now under the Creative Commons license is also something I'm not qualified to say. It might be better to change the description to something like "Solve the Project Euler problem here" (where here is a link to their page) and remove all actual PE text.

- This is not only a problem of license, but also to be fair with other projects. And one of Euler Project rules is that those who have found a solution accept to not publish it. To be honest, this rule doesn’t apply to problems 1 to 100. Here is what is stated in Project Euler “about” page:
- However, the rule about sharing solutions outside of Project Euler does not apply to the first one-hundred problems, as long as any discussion clearly aims to instruct methods, not just provide answers, and does not directly threaten to undermine the enjoyment of solving later problems. Problems 1 to 100 provide a wealth of helpful introductory teaching material and if you are able to respect our requirements, then we give permission for those problems and their solutions to be discussed elsewhere.
- But I’m not sure that simply referring to some Project Euler problem without any added value respects the requirements.
