Can you help me to convert/make my code more functional-style or OOP and safe?
I wrote a code for my needs (collecting YouTube links from a page) and it is simple, but now I just want to know what can I do just to make it a better and properly written one? For example I think I should have try ...
So I'm quite a beginner with Java and just this month started learning about GUI and JFrame so naturally the first thing I wanted to do was build a Minesweeper Game. Apparently that's a common thing for beginners. However, I may have bitten off more than I can chew. The game works fine and all, b...

MIDI is a serial representation of control signals to a sound generator. Typically, a noteOn message initiates the attack phase of a sound at a given pitch. The note will continue through decay and sustain phases until later, a noteOff message initiates a release phase to te...
Two years ago I wrote a short vector optimized dynamic array type (std::vector), for use in an image analysis library. I don't think boost::small_vector existed at the time.
The use case: Images in this library can have any number of dimensions. But obviously images with two or three dimensions ...
I just found a whole bunch of plane tickets that only have a start and destination on them. I also know the route started in a certain city. I would like to recover the (alphabetically) first possible route a person took using these tickets. I added some examples in the doctests.

I want to perform the following procedure:
I have two vectors x=[1,2,3] and y=[5,7,9]
I want to take first element of x and then add each element from y to it, then I want to take second element from x and add each element from y to it and so on... Finally, I want to save each result from each ...
I have finished my code for Conway's Game of Life. I am looking for any advice on how the user can input the starting alive cells. My teacher gave me advice to read it from an external file, but I would like to see multiple solutions for this. At the moment, I inputted my starting cells, but I wa...
I am right now learning to code and I just finished a challenge. It'd be lovely if you can review my code and tell me if I need to improve something (which is probably true since I am a learner). Below is my code pen.

I sometimes wonder how I should expand class names when I write a specific subclass.
For example, lets take a class

}
Now lets say I need specific subclasses for different types of cars, e.g. a class for fast cars and a class for slow cars because...

I provided an answer to a question on SO about a generic linked list. I just had the curiosity of having my code peer-reviewed as I wrote the code specifically for the answer.
That is, I have not implemented a generic linked list before, and would like to see if there are minor issues with the c...
Recently I started fiddling around with pathfinding. I created a WayPoint component to determin a possible way to another actor which is defined over other waypoints. My grid is looking somewhat like this:
The goal was to find a way to the red circled waypoint. A waypoint can have up to eight ...
I'm attempting to implement this pseudo code.
I'm not entirely sure that I've read the first few lines correctly, so anyone who could state them in plain English would have my gratitude.
My "random graph" is undirected and simply has edges that are added/excluded based on a coin flip.

This is the "largest" VBA project I've worked on, but perhaps not the most complicated. The meat and potatoes of it basically copies and pastes data from 2 source tabs into 1. A large piece of the code was broken out and refactored into sub procedures. Variables such as "DEM_Name" are dummy names...
Personally, I'm not a fan of this at all. You're right that it's ugly, but we can fix that.
To boot, we're going to remove every single if statement here.
Let's talk about a quick mathematic property of what we're doing: we can get the midpoint of both sides of the array, then round up and/or d...

Let’s start with the painful truth:
Too many people experience Stack Overflow¹ as a hostile or elitist place, especially newer coders, women, people of color, and others in marginalized groups.
Our employees and community have cared about this for a long time, but we’ve struggled to talk about it publicly or to sufficiently prioritize it in recent years. And results matter more than intentions.
Now, that’s not because most Stack Overflow contributors are hostile jerks. The majority of them are generous and kind. Sure, a few are… just generous, I guess? But our active users regularly express thei …
I am trying to compare two vectors which are of size of multiple of 4. Each vector block has a unique number it e.g {0,0,0,0}, {0,0,0,1}, {0,0,0,2} or {0,0,0,0,0,0,0,1,0,0,0,2} and {0,0,0,2,0,0,0,1} so on. I first divide the vector in block of 4 and than compare it and save the block which is not...
I'm interested in reducing the repetition in the doPost() method of my servlet. Specifically, I don't like the loop and error handling repetition.
Any other refactoring advice will also be helpful.

What I wanted to do was make a GUI-ish thing in the terminal as I have no experience with PyGame or the like. It works, but is it nice? Okay, I know it's abhorrent, but how can I improve this?
If any clarification is needed, as I am terrible with comments, please leave me a comment.

What is an efficient way to implement the Mergesort algorithm in Java such that it meets the following criteria:
Must be multi-threaded.
Must retain the Mergesort time complexities.
Must be in-place implementation, no copying arrays.
Must use Java Collection classes, not an array.
Must work on ...
