I'm working on a simple General Game Playing AI library. The idea is that it should work with almost any kind of game, with a minimum of configuration. At the moment, I have it working on 2 player turn based games like Tic-Tac-Toe, Connect 4 and chess. And it works quite well. It uses the Monte C...

I have a simple program with a background thread that simply draws a spinning "busy circle", at a rate of 200ms per update:
while (true)
{
this_thread::sleep_for(/*200ms*/);
// Draw spinning circle with 6 images, rotating.
}
htop and top always ...
I'm not sure if the time complexity is O(n) or O(n^2). Can someone please clarify? I want to say its O(n^2) because of the traversal in the destructor and the traversal in findMin().
findMin basically just traverses the doubly linked list and finds and returns the minimum value.

I have just attended a code test of some code testing site, and I think one question seems easy but I didn't get a high correctness (57%), so if anyone can review this code snippet, I would appreciate it.
In summary:
Given an array A, with dimension N, 1<=N<=100000, A[N] within range of [-10000...
This code (Windows Forms) shows a series of timers so that the user can manually time a series of tasks. I decided to put this together today because next weekend I want to go through an activity (about 4-5 distinct tasks) and see how long it takes.
The main window is where all the action takes...
I've implemented a stack using a singly linked list and would like to know if there are any things I could improve on. Thank you!

I'm looking for a bit of advice on improving my solution I submitted for a codility test. Overall I'm pretty happy with it but i think I can improve especially with my use of includes.
Here's the task

My program intends to capture video streams (in mjpeg) with OpenCV and upload the captured frames into Google Cloud Storage for later processing. I am expecting to capture ~15-20 frames per second and expected to upload nearly all frames within a second.
The trick is, the script is running on Ra...
In one of my React components, I want to use props when creating a styled-component to determine which tag to use. Specifically I am looking for what's in props.headingLevel to decide which heading level to create. E.g. h1 or h2.
All of the styled-components examples show components being create...

Just to enjoy, I want to implement selection and bubble sorts algorithms without looking any implementation by my own efforts 💪💪. Is there any redundant/lack part(s)? After improved their implementations, I think to try to write them down as recursive, can I ?, any hint?

I am working on this excellent tutorial, but in the end my first test is not passing, due to the fact that I can clearly see I am creating two different arrays (and pointers), and trying to compare them with one another.
Now the tutorial from what I can see leaves out a few lines of code that I...
Most of the SE sites are down for few mins, but MSE is working fine.
I wrote a program which gets two sorted arrays a and b (with sizes m and n respcetively), and calcuates the median node of these arrays without merging them.
Here is my code:
#include <iostream>
using namespace std;
int findMedian(int a[], int b[], int m, int n);
int max(int a, int b);
int min...
I can't seem to set adjust the width properties of the elements in the table below, and I'm not sure why. I've tried using both literal width="100" and inline styles width: 100px & max-width: 100px, but for some reason the elements are much wider than the image elements inside them.

I don't need a lot and I don't need for my code to handle everything. Even now, I'm just looking at handling serialization. I'm pretty much building on it as needed. I am trying to support vectors right now and am looking for an idea on how to extend what I have a little to support this. Basi...
Does this modification overlook any fundamental behavior of Node Express application 500 or other errors? Admittedly I only tested 404s.
When creating a new project from the Visual Studio 2017 'Basic Node.js Express 4 Application' the error handling code is in app.js like so.

I have designed the Control Unit of the CPU in VHDL. It works properly and produces the expected simulation waveforms. Nevertheless, I feel that my existing code can be improved considerably.
My control unit essentially consists of three processes: operation decoder (this is the lengthiest pro...
I am trying to pick up Haskell!
But I feel like my code is a bit painful to write and read.
Do you have any pointers on how to improve its readability / style?

This code should partition a list into two subsets of the given list that add up to the same number: for example [15, 5, 20, 10, 35, 25, 10] -> [15, 5, 10, 15, 10], [20, 35] would be a valid solution. I'm looking for any tips to improve code style (be more Pythonic) or performance (mainly improve...

I am working on a messaging service to use in a modular server scheme. Long story short: The server has modules, each module can "subscribe" to a "topic" (message Type). The MessageService is responsible for sending, receiving and parsing messages.
So this is sort of a question/code review.
