comment Why does Fourier give a shifted frequency?
Uhh, almost too long for a comment. So, using a number of samples that makes a near integer number of sin's to fit fixes it. Using a lower sin amplitude. Windowing with some window with smaller secondary lobes. Also, in theory your data range should go up to slightly less than 1/dt, but that won't make a difference (and if it did, it would be in the wrong direction)

comment Why does Fourier give a shifted frequency?
You are sampling your squared sine less than a single period. This means that your spectrum will be samples of some deltas convolved with a fat Sinc (and the samples won't happen to fall on the sinc's zeros). Given that Sinc's fatness, the fact that your sin has high amplitude compared to the cos, that the cos frequency isn't very far away from the sin's (just about 9 sinc's lobes away), that the sinc decays slowly (compared to other common window transforms), that sinc's lobe is comparable to the cos's and makes it appear shifted

In the meantime, a subquery seems to work planets[All, "Moons", Query[{Median, Length}], "Mass"]

comment Operator syntax for Merge-like Query
Am I wrong to understand from the documentation that your proposed short query syntax should work?

No solutions provided but I got the impression that it will be fixed soon

comment How to generate and label multiple histograms as Query operator(s)?
It used to be documented before the final release. And it will go away, but I am hoping as it goes away, some other function will take its job because I find it pretty useful

Are there other sample pairs of images?

comment Possible bug involving Dataset/Query and RightComposition
It seems like a bug to me. As if only the last ascending operator is applied if the first of the chain is descending. If this is true, you could make any op descending/ascending with something like Select[True &] /* desc1 /*.../* descn /* Function[asc1 /* ... /* ascn@#]

comment Defining a sequence slot programmatically
Where seems to have a definition intended to catch things like Where[{x,y}={2, 3}, f[x,y]] that they added last and is never tried. To fix it, use DownValues[Where] = RotateRight@DownValues@Where

comment Setting and changing MetaInformation for arbitrary objects
@MichaelStern luck. I just felt it was sensible for nested temporal data's to be flattened out, tried it and worked.

@LeonAvery you want a workaround to set the background or to set all the elements to a value?

Perhaps titanic[Composition[Histogram[#, ChartLabels -> Automatic] &, Pivot[#, 2] & ], {"age"}]. (but Pivot is probably going away soon)

comment DeleteDuplicatesBy is not performing as I'd hoped. Am I missing something?
@JacobAkkerboom you are right, that output doesn't make sense to me either
