I got an error when I ran cv2.fillPoly(color_warp, pts, (0,255, 0)) and then recognized pts needed to be int32.
But why does it need to be int32 ?
pts holds an array of array of points on an image. An image is a matrix of Scalars. It is indiced by (X, Y) values which can be stored quite adequately in int32.

So I found out that any variable or constant in swift is a tuple. For example, variable x below is a tuple
var x = 15
and following statement is valid and evaluates to value of x as the first element of tuple
x.0.0.0.0.0.0.0.0.0.0.0 // outputs 15
I'm wondering why the language has been built to accommodate this. Any known (or outworldly) use case?
I don't know can it be the right answer, but it gives some information and shows that it's a known thing. Look this 2 sections:
Special: The 1-Tuple
Bonus Track: Tuples All the Way Down

How to write something
if !inBoundary then do
printfn "no it's not within the boundary"
You can use the not built-in function (and omit the do keyword after then):
let inBoundary = false
if not inBoundary then
printfn "no it's not within the boundary"

what is the shortest code to copy all checked items from a TChecklistBox into a TStringlist ?
( for a TListbox I can you the assign function to add and extract a TStringlist with data)
Using plain vanilla Delphi (i.e. without any third party libraries) you just write a for loop:
StringList.Clear;
for i := 0 to CheckListBox.Items.Count-1 do
if CheckListBox.Checked[i] then
StringList.Add(CheckListBox.Items[i]);

I have an arbitratry string, something like QKOTRFLARGEBRAAFFALGORITHMMIMISSSTUPIDCROCODOLCONCEALEDKSBABA...
and I need to tell LaTeX to split this string neatly into lines. It is not a word, there should be no '-' when splitting line. Just fit these data into lines, break wherever it suits.
I have successfully used the seqsplit package for that.
