Did anyone check if he actually isn't the author of the tasks?

hobovsky commented 3 years ago

Maybe being the author is not the only relevant thing here?

I think it's possible that the way how problems are licensed in one system could forbid submitting the same problem somewhere else, isn't it?

If it's rules of another site, it doesn't have to do anything with anyone expect the author and that site. If they signed it legally, which is very unlikely and too much to assume by default, my understanding is that transferring exclusive rights usually ends up in situations too complicated to understand even for lawyers. (I could ask the same way, what if the other sites copied the problems and made it look like they were published there earlier than here. That's not impossible either, but rather improbable for well-known sites.)

how? I don't see the name of the author of the challenges, there.

Note: looks like a lot of those links are dead => ?

error256 commented 3 years ago

Also, should trivial katas be marked here somehow? For example, "Kill K-th Bit" already has the task in its name and it's trivial, so it should be fine if the story is removed from the description.

What does the checkmarks mean?

What does the checkmarks mean?

@farhan443 : Those kata have been handled, and they''ve been retired now.

Note: looks like a lot of those links are dead => ?

@Blind4Basics : No, they're not. On codesignal, problems gets incrementally unlocked (that is: next level can only be unlocked if the last level has been completed(or one can unlock it paying some "points/coins"). As of now, the only link that was dead for me was Is infinite process?:

Usually community-contributed problems are licensed by something like CC BY-SA, and the author owns the right of the written problem.

Besides, the author always have the right to re-license their original work on other sites (unless exclusive rights were obtained), so this usually isn't a problem. Of course, the author violating the license of an existing problem in the first place is another issue...

Simple Fun #85: Polygon Perimeter can be safely retired, it's already a duplicate of Land perimeter.
