I was practicing c++ and data structures and wrote my own implementation of a doubly linked ring. I would love to improve my code a little bit more and would need help from the community. Here is the implementation I have #ifndef BIRING_H_INCLUDED #define BIRING_H_INCLUDED #include<iostream> #...

So I implemented drivers for I2C and USART using interrupts with some guidelines online, and was wondering if I can get some suggestions from a design point of view even though the code works (tried at 9600 and 115200 baud rate), but I do get a hardfault upon using two different baud rates at rx/...

After some time poorly designing my web applications' backends (mixing database calls with the controller, etc.), I have decided to try the "Clean Architecture" approach. In this example I have a REST api users which allows you to get a list of all users in MongoDB and to put a user inside the d...

The standard library heapq in python doesn't support updating keys as a public method, which makes it hard to be used as a priority queue. Although the official documentation has suggested a workaround, it is somewhat convoluted. So I decided to implement my own priority queue as a min-heap. Her...

I know there's already a whole bunch of similar attempts at this and I've looked at a few of them to get some tips. My main aim with this was not to write anything fancy. I wanted to create a simple game with the most basic functionality but write it really well. In other words I'm more intereste...

Requirements I have a table of the different diagnoses a patient has received, with the date the diagnosis was first recorded. It so happens that in medicine, diagnoses are recorded as codes from a huge list called ICD10, and sometimes several different codes are related to a single disease, for...

I have 2 asynchronous return values from 2 different classes, one from HealthKit, the other from MotionManager. I combine the outcome of these classes through a combinedViewModel. The code works, but I want to know if it is properly formatted and if all functions, ... are used in the right place....

I have just read the Chapter 5 of Data Structures and Algorithms with Python. The authors implemented hash sets using linear probing. However, linear probing may result in lots of clustering. So I decided to implement my hash table with a similar approach but using linear congruential probing ins...

I have a matrix like so: cell = [[1,2,3,4,5], [6,7,8,9,1], [1,2,3,4,5], [6,7,8,9,0], [0,1,2,3,4]] It's a 5x5, so mapped out it would be: 1 2 3 4 5 6 7 8 9 1 1 2 3 4 5 6 7 8 9 0 0 1 2 3 4 Now, the contents change all the time. What I want is to have a function called check_valid...

I wrote some code to estimate the solution to the following problem: If you break a line segment at two random points, what is the probability that the new line segments can form a triangle? The code is relatively simple, and it works. However, I can't shake the feeling that each of the thr...

I made the bellow macro to create a time line in excel. It shows the working days, the week numbers and the month together with the year. First I start with projectstart date and projectend date. As these dates can be any working day and I want my timeline to start on a monday and end on a frid...

I am writing some code that performs a simple time-history integration solver (Newmark method for structural dynamics) and I looking for some suggestions in how I can improve the performance of my code. Currently, I am calculating a parameter called displacements for many time steps (think on the...

For learning purposes I'm writing a very simple mqueue based file transfer server. Below is a thread function that takes care of an incoming request: static void * handle_client_request(const char *request_string) { char request_pathname[_part_delim_alloc_size], request_fifo_name[_...

Last night I had to build dropdown for the menu on the website that I'm working on. As I'm still React newbie I first looked if there is some package for what I'm trying to achieve but there wasn't, so I had to try to build it on my own. So the menu has its menu items, whichever is hovered it sh...

I'm doing a little more grad school, and for a group project I wanted us to be able to quickly share and update our project, so I coded up a Python script to handle that. As usual, I'm proud of the work, but I'm here for you to tear it to shreds again. First, the imports, some globals, and the m...

Please review my code for the performance and correctness, everything works and we get visible wifi access points by opening http://esp8266_ip_addres/hotspots except on refresh the values gets duplicated. and does not reset as I have done in the else block. #include <ESP8266WebServer.h> #include

I am working on a hobby project implementing a card game server with scotty and websockets. The implementation of the game itself is more or less done. Now i am working on the server and I have an idea on how to structure it. Since I have never seen this approach anywhere, I am unsure whether I ...

This question involves C++ code in the context of numerical simulations of some physics. I have a class driver which provides certain core functionality, e.g. setting up a cartesian grid, etc.; the actual functionality is not important here. The header looks like: // driver.hpp, for illustratio...

How can I enhance the design of my objects and their relationships? Right now, there seems to be a tight coupling so I feel like I've violated some rules about data access and responsibility. Definitions: TaskService - Initiates & manages workflow, and encapsulates required dependencies/serv...

I'm currently implementing a Minesweeper clone in Java using Swing. Rather than updating the tiles like so @Override protected void paintComponent(Graphics g) { super.paintComponent(g); for (int row = 0; row < rows; row++ ) { for (int column = 0; column <...
