Since legals topics can be particularly hard to navigate in the USA I should probably state that I am not a lawyer and have zero experience with legal topics.

comment Missing: KeyGroupBy?
A simplification of my version, GroupBy[Normal[data], PrimeQ@*First, Association]. Also, thanks for posting!

Since WB 3.0 is not yet released, you should probably report such problems to Wolfram Research directly. If it's a bug, they need to know about it so they can fix it.

comment Issue with very large lists in Mathematica
@AlexeyPopkov I didn't forget, but it was late at night and I wasn't clear enough. My point was that I see a linear increase which is exactly what one would expect.

@Mr.Wizard I wasn't going for speed at all and it's a minimal modification. Also, I'm not particularly confident in this area yet.

Thanks, this is much easier to follow.

comment Changing BarLegend border style
I'm really glad you asked this. I needed this in the past but I never had the time and persistence to solve it. The problem is that if I really need it then I usually don't have time to find a good solution. It's a bit paradoxical, but it's sometimes easier to solve other people's problems than our own.

comment Issue with very large lists in Mathematica
I tried to test access times like this: arr = Table[RandomInteger[10, 5].x^Range[5], {1000000}]; Table[AbsoluteTiming@Do[arr[[i]], {i, Length[arr]}], {10}] I see a linear increase as arr grows. However, the very first time to iterate through the array is much slower than subsequent times.

You can consider replacing AssociationMap[First[#] -> # &] by Normal. Here's my right-to-left version: Association /@ GroupBy[PrimeQ@*First] @ Normal[data]

@shrx Are you using the very latest RPi release? (Just curious, I don't have the RPi handy at the moment.)

comment Sum with Levi-Civita
Instead of LeviCivitaTensor[...][[mu,nu,alpha,beta]] you can use Signature[{mu,nu,alpha,beta}].
