The video that opened my eyes to APL was “April, an APL Compiler for Common Lisp” by Andrew Sengul:

Thanks for pointing the missing glyph. I will paste the correct code.

  backbias←{+/,⍵}
  logistic←{÷1+*-⍵}
  maxpos←{(,⍵)⍳⌈/,⍵}
  backavgpool←{2⌿2/⍵÷4}⍤2
  meansqerr←{÷∘2+/,(⍺-⍵)*2}
  avgpool←{÷∘4{+/,⍵}⌺(2 2⍴2)⍤2⊢⍵}
  conv←{s←1+(⍴⍵)-⍴⍺⋄⊃+/,⍺×(⍳⍴⍺){s↑⍺↓⍵}¨⊂⍵}
  backin←{(d w in)←⍵⋄⊃+/,w{(⍴in)↑(-⍵+⍴d)↑⍺×d}¨⍳⍴w}
  multiconv←{(a ws bs)←⍵⋄bs{⍺+⍵ conv a}⍤(0,(⍴⍴a))⊢ws}

I like the 19/20 French system.

Numberphile has a nice video about it: https://www.youtube.com/watch?v=QzrRkhU248A

Thank you! Now everything make sense.
I like it.
Google spreadsheets have been neglected for a long time.

The sad part is that if this new project succeeded, it could catch google's attention and they will be able to launch a better version in a very short time.

They have too much power to strangle/buy any innovation. Just to let them die.

This is why I don't like google anymore.
