@Soaku You are given an odd number of white balls and the same number of black balls. The task is to enumerate all the ways of putting balls into bins so that in each bin there is an odd number of each color.
Suppose you have an odd number of white balls and the same number of black. How many partitions have an odd number of white balls and an odd number of black balls in each subset?

A Walsh matrix is a special kind of square matrix with applications in quantum computing (and probably elsewhere, but I only care about quantum computing).

Just a warning: I expect this to be very difficult, perhaps even impossible. I have seen people downvote challenges they believe to be too difficult - don't do this, have an attempt instead. If I haven't got an answer in a month, a bounty will be put up for the highest scoring answer

TIL where Windows Subsystem for Linux comes from. Apparently they had a project to get Android apps to run on Windows 10 as an attempt to save the Windows Phone. By the time they realized nothing would save it and killed the phone off, they already managed to get the Linux kernel to run on Windows.
@fergusq For the record, the question was not Should we change the levels, the question was Should we change them now instead of sometime down the road
@DJMcMayhem I know. That is why we should oppose the raising of them during the full graduation. If we can voluntarily raise them now, why shouldn't we be able to voluntarily lower them then?
For example: I fully agree that rep can be gained easily without necessarily proving skill. But the important thing about rep is that it proves familiarity with the site. And needing to prove familiarity with the site before being allowed to edit/close/delete posts is a good thing and IMO takes priority over some useful things like seeing vote counts
I don't think that skill should even be relevant. Everyone who participates should receive reputation (for the voting is not about the skills, but about how relevant the answering is).
We should also think about the current situation. Do we have any problems with the current levels? If not, the raising is not needed.
@DJMcMayhem I think you as moderators should also try to negotiate with the staff to make privilege levels more suited for this particular site. Like seeing deleted posts is much more useful here than at for example Stack Overflow.
@fergusq I do have problems with the current level. I've seen too many worthless edits from low rep users just for the sake of increasing their edit count. And new posts can be opened and closed several times by lower rep users before finally figuring out whether it should be closed
@fergusq Sorry, I have a lot of thoughts but I'm typing really slow on my phone and I may need to go soon
@fergusq I can try, but I think it's highly unlikely that they would adjust one privilege level on one site. What reasons do you think seeing deleted posts is more valuable here than SO? I'd like to hear your reasoning
@DJMcMayhem 1) Sandbox posts are historically important (for their comments, for example), but deleted. 2) Posts that do not follow the rules of the challenges are deleted, but they are useful for other people who want to follow the specs, and when answering similar challenges.
@DJMcMayhem for the point about closing posts, I agree with you in the sense that it can result in the challenge constantly being closed/opened, but then again, everyone is typically of a different opinion and it is hard to come to a unified conclusion
I do think that access to deleted posts is useful, I can remember several cases where a user posts an invalid answer that is equivalent to a deleted one
@Cowsquack This. It can also be a symptom of that the so called "meta consensus" isn't a consensus at all (the use of that word is ridiculous). The meta system is also flawed similar to the reputation system, in that voting does not work and the earliest voters can determine the outcome and the new users have less say. This has resulted in our contradictory "consensuses".
This is a repost of other's prob because the author deletes the problem once possibility to solve this problem show.
We define the prefixes of an array to be the first n values in the array, where n increases between 1 and the length of the array. For example, the prefixes of the array [1, 2, ...
a couple of ppcg users are planning to create a "better ppcg", an improved website for code golfing that hopes to fix the flaws of ppcg.se, you seem like you would be interested in it, the chatroom is here
@cairdcoinheringaahing Abuses which general rule about proper quines? If it's reading its own source code, then I think that doesn't make it invalid, because at least the rules of IOCCC specifically allow that.
Is this a Boggle pad?
