I am learning Racket and implemented a BST insert function (insert tree n) where the format for a BST node is (left-tree value right-tree).
Example
'((() 2 ()) 3 ()) is isomorphic to:
(3)
(2) ()
() ()
Therefore (insert '((() 2 ()) 3 ()) 4) yields ((() 2 ()) 3 (() 4 ())):

I want to check in my if and else if statement if the inputs form a square or a rectangle, now my if and else if statements seems to be unreadable, now I'm thinking of ways to improve it.

I've been reusing an error class in Excel VBA projects for a few years now and I'd like to see if there are ways to improve it. Any suggestions for style, code, etc. are all welcome.
The log file is usually written to a file server so multiple users can access it. I have changed the log path to ...
I have just begun learning functional programming and Haskell.
This is my attempt to implement a solution to Graham Scan Algorithm in Haskell. Note that I am not even sure if this is how the algorithm works. But I believe it to have a O(nlog(n)) time complexity. However, I am still not quite th...

I have a string like this:

I have an interesting problem to solve and despite having a running solution, I was wondering where I could improve it.
In a range from 1 to 1000, I want to create an array with different iterators according to the current interval.
So, from 1.0 to 2.0, the increment should be 0.01, from 2.0 to ...

I have created a very basic script that periodically writes some data into a database:

I'm making multiple calls to the server and creating pages and posts in yaml format from the API in my gulpfile. The functions seem similar enough that I could just make one function for all of them.

I'm looking for some critique of my simple console game application I made. I'm teaching myself to code so I don't have a teacher to "grade" my stuff for me, so this is where I go! I'm using system.timers btw.

dumb question. In any ROT47 implementation, I see this:
crypt = '!' + (plain - '!' + 47) % 94;
or
crypt = chr (33 + ((j - 33 +47) % 94)))
The point is the modulus operator. I feel dumb for asking, but why? Is it to keep it within a range of characters? I'm sorry for asking such a dumb que...
I have a huge Google Photos directory that is difficult to navigate - there are just too many files so I thougt I need to sort them somehow. I decided to make it simple and group them by date-taken. As I always wanted to learn python I thought I'll give it a try so this is my first take on it.

I´m doing a grid with 34 lines and 26 colums, but I don't know how to do it like the image in the console app (In the colums represents the letters and the lines represents the numbers).
How can I do it and make it work, can someone help?
