This cube has a positive (blue) and a negative (black) bar on each face. That is 2 flat bars per face. On each face 1 bar has the opposite polarity to the other. I have hidden the faces to make the problem clearer.

The Nine Days of Av are a religious observance in Judaism that takes place during the first nine days of the Jewish month of Av (corresponding to July/August). The Nine Days begin on Rosh Chodesh Av ("First of Av") and culminates on the public fast day of Tisha B'Av ("Ninth of Av").
The Nine Days are part of a larger period of time known as The Three Weeks, which begin with the public fast day of the Seventeenth of Tammuz — commemorated in Judaism for the time when the forces of Nebuchadnezzar of Babylonia broke through the defensive walls surrounding Jerusalem, generally accepted as happening...

Not an example of a puzzle song but a true contradiction nonetheless, the most repressed-by-now guitarist playing the most freewheeling journey of the mind when he had the chance (salute', Nugent, muthaf that you turned out to be):
LIBER (A god, apparently) + [w]ATE[r]([s]) = LIBERATE ("save one's bacon")? Seems a bit off due to the overlap in etymology and also the supervisor part doesn't seem like take off side letters to me

@Sp3000 That looks as if it might work, but I don't really understand how to get -ate after removing the supervisors from waters. And doesn't liberate mean to save someone else's bacon?
Oh, I think it's a good lead. Perhaps the solvents are acetates and we can remove aces (supervisors?) to get -tate. Unfortunately, arestate, odintate and Isistate aren't words. :(
Let's just say I may or may not have impulse bought Sympathy upon getting one of my first few paychecks... whistles (no regrets so far though, despite my limited use of it)
(On a side note, it looks like Crossword Unclued already covers the crossword tools I had in mind, so I think I'll skip out on the meta post: link 1, link 2)
(On a different note, @Deusovi I didn't realise Across Lite had a TXT format and it looks like Sympathy can do that, so I could have just posted that after all... assuming I had entered the clues)
One of those posts is descriptive (no expiration date) and the other seems functional (didn't try it, though).

... all the while I've been working on this lateral-thinking solution for how to make a square from a rope. Might be posted yet, who knows, but why not here first:
This was a challenge given to us in our Team Building exercise in an MBA course I took. Needless to say our team didnt do well. So I am asking the Stack community if there is a clear way.
We were in a Gym with NO equipment. We had 3 players on our team. The instructor gave us a long rope (may be...
But I understand the ideas behind making something enjoyable, for all who want to participate, but at the same time not so simple and easy that it's no fun in the long run
Making something that appeals to everyone is nearly impossible because of how many different people there are and how many different opinions and interests there are.
I've learned in life you can spend all your energy trying to make everyone else happy, but you often neglect yourself in the process. It's a futile quest, but one I will continue to pursue nonetheless
... thanks for coming back and giving me an excuse to start out on Fun'n'Game Theory, n_palum! To be continued when the time is right. It won't be published.

My challenge (I will refrain from calling it a puzzle for now!) was recently put on hold as off-topic since it was seen as more of a maths problem than a maths puzzle.
I therefore posted my second challenge ...
looks cool. but I still haven't seen a javascript debugger that gives me any of the confidence and feedback that VS does. I'll wait another few years :)
I have a question for y'all in chat, I just had a question that I answered put on hold, that I think was perfectly well on topic. maybe take a look and see if you agree? puzzling.stackexchange.com/q/53723/38342
Questions that consist of purely routine mathematical calculations are considered off-topic here. Questions that consist of purely routine anything-else would also be off-topic, but -- perhaps because Math Is Hard -- non-mathematical questions of this sort aren't so common.
I'm not sure what counts as "relatively little actual math". The solution is pretty quick, but just about everything in it is mathematical manipulation.
Yeah @Aaron - I'll also refer you to puzzling.meta.stackexchange.com/questions/6033/… - and particularly to the answer I just left there not that long ago. I think it answers your question pretty exactly.
I mean, it's possible to streamline the wording in Aaron's answer a bit, but really what else can you do? Establish with a line of algebra that it's a golden rectangle, take the arctangent, done.
> "Requiring "thinking" is problem-solving, and that's an element in puzzling but also one in solving math exercises; it's not quite enough. Nor is requiring the solver to find something which is "clever" but nevertheless directly signposted because there's literally no other viable approach to the problem. "
@Aaron I really don't think there's anything to be done in that puzzle that isn't essentially the same as what you did. (Or strictly worse, of course.) Sure, there are lots of constructions that lead to the golden ratio, but a lot of them are basically the same as one another :-).
@Aaron Anyway. that's from my answer to the poster of the same question you answered, when they wanted to know why it was off-topic here. So my answer to them is my answer to you.
The matrix given as below where you are supposed to put number from 1 to 25 in it. But the condition is that, the difference between the neigbours (horizontal and vertical) will be at least $x$.
$\begin{bmatrix}
a_{11} &a_{12} &a_{13} &a_{14} &a_{15} \\
a_{21}& a_{22} &a_{23} &a_{24} &a_{25} ...
So I came up with another probably very stupid riddle, but feel free to have a go!
