@joeltight Let's find some time to give you a personalised introduction. When are you available?

i'm getting a bit confused with terminology, specifically here: help.dyalog.com/latest/Content/Language/Primitive%20Functions/…
what's the difference between a value being 'simple' vs a 'simple scalar'? here, does simple just mean an array that is not nested, where simple scalar means a scalar value of rank 0?
ah nevermind, the page for 'depth' helped me understand the difference help.dyalog.com/latest/Content/Language/Primitive%20Functions/Depth.htm

@dogstar Next time, consider asking the APLcart?
 
@Adám aha! i should've thought of that, thanks :)
 
 
2 hours later…
@Adám What's the official position on the name of the site? "APL Cart" or "Apple Cart"?
 
@J.Sallé APLcart, as evidenced by the name in the top left corner and in the readme on github.
 
I do like reading it as Applecart though >.>
I think it rolls better off the tongue
 
@J.Sallé I read it as that too. Did you ask for the official pronunciation?
 
Yes, yes. I should've expressed my question differently I guess
Also, praise you for defaulting to a dark theme and adding the option to use a light theme instead of the other way around.
 
1:38 PM
@J.Sallé Ah, then applecart it is.
 
Nice. I assumed it'd be that but I had to ask >.>
 
@J.Sallé For sure. Someone who lives in white-land, won't be shocked by the appearance of a dark page, but can turn it off. Someone who lives in dark-land will fall over backwards if they get blasted with that all-white screen. That's also why I didn't include the current theme in the permalink generation.
 
As someone who lives in dark-land and falls over backwards consistently because of white themed pages: thanks a bunch!
 
@J.Sallé It is also intended to allude to upsetting the applecart in that it is a disruptive tech in the global APL documentation field.
 
@Adám I'm all for disruptive tech, so I like it
 
1:43 PM
@J.Sallé How do you deal with browsers defaulting to an all-white page as they begin to render it?
 
@Adám well, my new tab page is dark and my internet connection is fast enough for that not to be much of an issue. It's annoying when pages hang while loading, but I can't do much about that.
@Adám to make this 0{|⍺-(+⌿÷≢)⍵}(0 1 1 0 1 1 1 0 1 1) a train, I tried rewriting the dfn as |⊣-(+⌿÷≢)⊢, but that gives me the negative value instead of the magnitude. How do I apply the magnitude to the result?
 
@J.Sallé That's not what's going on. You're forgetting (due to using 0 as test case) that you want svg applied monadically to the right arg.
 
Oh, I see.
 
@J.Sallé So think: I want X f Y but I want g applied to Y first, i.e. X f g Y. Is there an operator ⎕ such that X f ⎕ g Y gives X f g Y?
 
2:00 PM
@Adám hah! I was about to do that
I had actually tried |⊣-∘(+⌿÷≢)⊢ and it failed because I forgot the parens around it
 
@J.Sallé Also remember that ⊣f⊢ is just f
 
Oh yeah
 
2:30 PM
 
@Adám oh nice. Summing the inverses in this case is the same as mean, I guess?
 
@J.Sallé It isn't summing the inverses, it is dividing the differences before summing instead of after summing. because (a+b)÷c ←→ (a÷c)+(b÷c)
 
Yeah I just noticed it. Thanks, I'll update the answer and explain it
Done
 
@J.Sallé Not right:
      ≢⊢ ⍝ Tally the elements in the right argument
    ÷∘   ⍝ Divide each element by that tally
   -     ⍝ Subtract those from the left argument
should be:
       ⊢ ⍝ The right argument
   -     ⍝ Subtract the left argument from the right argument
    ÷∘≢  ⍝ Divide each element by the tally of the the right argument
or something.
 
2:46 PM
Oh, I see
Fixed
 
 
1 hour later…

What does BoolList⊥1 compute?
 
 
4 hours later…
8:51 PM
@dzaima Yup, looks like a regression in 17.0. I'll report that. Thanks!
