To do that I am iterating through an array of 50 commands, trying to run each with flags -[a-z] and then making anagrams out of the successful options. It is working and here is what I h...

I'm using this class so that objects can find other objects that are near them. Each object has a position and radius. Objects are added to the Grid. If they move then they call update with their new position. An object can call retrieve to find which objects are around it. How can I optimiz...

I use YogaKit and it extends View with the configureLayout method:
someView.configureLayout { (layout) in
layout.isEnabled = true
layout.width = 100
layout.height = 10
layout.marginBottom = 25
}
as you see this method expects a closure.
Now I have exten...
That is, show how many times did 1 occur, and for 2, ... and for 6:

tally[rnd] = (tally[rnd] || 0) + 1;

Just started out with CIS 194 on Haskell and wonder what the more idiomatic way to solve this problem would have been.
This code is supposed to generate all possible combinations of 6 given colors up to a given length. It works, but I think my solution is not that elegant. The suggested solution...
I just wrote a PHP code to register users.
It's called through AJAX and it looks like it's too slow because it often sent me a .status = 0 that it means it took too much time to proceed.
If i replace my php function that register only by :
echo "Ok";
It always sent me a .status = 200

Exercise description:
"Write a program that takes a double word (4 bytes) as an argument, and then adds all the 4 bytes. It returns the sum as output.
Note that all the bytes are considered to be of unsigned value.

Over the weekend this article inspired me to write an ASCII string implementation that avoids array allocation during basic operations like Substring and Trim. It's still a work-in-progress but I think this is a solid foundation to build off of and wanted some help checking my logic/maths.

how can i solve this Q:
Python program asks user to choose a unit of measurement:

user chooses Kelvi...
I would like to hear your recommendations on when to use JavaScript's const over let, especially when applied to mutable objects as demonstrated in the following comparative code samples:
Strict preference of let:

While trying to understand monad transformers in Haskell I came up with a sudoku solver based on a combination of the ST and Reader monad.

This is a follow-up from this post.
It all works, but I think the code could be made to work faster and to be more stable. I have made improvements and updated the code in this new question.
