8:26 AM
So I've been trying to do the 19th exercise, the top-left to bottom-right line one, and while trying to do something clever with ¦ (having hit 8 bytes with two separate more straightforward approaches) I realized that I don't really know how to use it at all
(got one of them down to 7 actually, but still two bytes over par)
 
8:41 AM
...6 now
and the thing I was going to do with ¦ would absolutely not help but that quick still confuses me
with trailing spaces
and somehow all that progress was inspired by being confused by ¦
 
9:13 AM
applying the same idea I've hit 7 bytes on 21 and 22 (checkerboards) and... it seems like they should only need 6
 
9:32 AM
similarly I got 8 on 20 (the X one)
 
 
14 hours later…

@UnrelatedString It's not too bad of a quick to get the hang of. Basically, it takes an atom, a list and a list of indices, and applies the atom to the values in the list at those indices
So H[1,2,3]¦ would halve the first three elements of the input list
 
Huh, it is working fine now that I'm trying it on lists, so I guess the problem was just that I was trying to use it on an integer and it didn't rangify properly
