This function runs thousands of times on different files, causing the UI thread to lock up. It gets called in several different places in the program. How can I make it run asynchronously? The issue is that it returns a string and also takes arguments
public string CopyFile(string sourceFile, st...
Im creating a window class in C++ to provide a bit of abstraction for a GLFW window. To me it makes sense to add a key_callback as a method in my class. The issue is ofcourse that GLFW is written in C, and so it requires callbacks to be static.
I found that GLFW has a glfwSetWindowUserPointer fu...

I am relatively new to C# and would like to see if what I have been using for my exception handling, message and logging is along industry standards. I have created a simple class for the Error Handler and for the logging I use Log4Net. After reading Clean Code, I was thinking about separating Di...
I wrote a code like below - It is nuxt.js, which is one of the Vue frameworks. This code will be expected to
When change event triggered, update data value. There would be some logic to alter passed data
At the same time, it connected with data value to apply input box changing

I started out creating a simple game in an Object Oriented way to practice.
The rules are pretty simple
There are two players
You let one player choose if they want Heads or Tails.
You assign the leftover option to the other player.
You simulate a coin flip and say who won that game.

I'm attempting the Graph Algorithms section in CLRS right now. Here's an iterative DFS using a stack called nodes.
T is a vector of pair(s) of ints which store timestamps for each node.
T[node].first = discovery time
T[node].second = finishing time
P is a vector recording Parents for each nod...

One ASP.NET MVC application has a login page. In this login page (and only for this page) I'm using a background image. This background image is changing every week.

I have two types that don't share any interface but have similar properties and that I need to compare for equality.
One of them is comming from a 3rd party library and one of them is mine. I obviously cannot add any interface to the foreign type and honestly I don't want to create any wrapper f...
I've searched everywhere about how to use awt's canvas, but there's one thing that I just don't get: how do you actually call the paint method?
Yes, you have to override it to draw whatever, but when, where and how is it called in the program? Where does that graphic parameter come from?
What I...
Actually, this is not my own code but because I wanna use it and this problem bothers me frequently, I wanted to check it out here:

I'm planning a feature which would have a dynamically created number of input text fields(by a button click) which I will later be collecting.
As of today I have been assigning ids by a running index to each input element and looping through them for collection like so:

I am writing a data preparation class that should work differently on different database types. I would like to assert that the class is instantiated with allowed database types. So far best solution I came up with was:

Consider the following Java code:
Stream.of(1, 2, 3).map(i -> i*i).mapToInt(Integer::intValue).sum()
This is pure and will result in the same answer every time. No problem there. However, let's say that we now want to utilize cloud computing and want to map each value to the result of a networ...
I recently rewrote my object pool design to O(n) complexity. I did this using a linked list, which is not native in javascript. It does not, unfortunately, automatically assign null to a value when you free it :)
const Pool = function() {
const Free = new WeakMap,
Next = new WeakMap,

Also someone please give me a instructional video on how to work on this website. Its so frustrating.
This code is looping over polygons geometries vertices in order to create a list of deltas (distance) between vertices coordinates to compact the geometry before sending it into the web.
geometry output is expected to be on this format: [[x0, y0, (x0-x1), (y0-y1), (x1-x2), (y1-y2)]]

I am trying to create a directory, but I have to check whether /usr is present initially, later /usr/local is present and so on, is this an elegant way of writing it?

char str[] ="/usr/local/mnt/";
char path[40] = {0};
char temp[40] = {...
So I started learning Rust a few hours ago with the Rust Book (2018 edition) and as part of one of the exercises decided to make a temperature converter. I wanted to make sure it handled all inputs properly in an idiomatic fashion. The code is as follows:

Please review my Breadth-first search algorithm implementation in Java for finding the shortest path on a 2D grid map with obstacles.
The findPath() method receives a map array of integers where 0 is an empty cell, and 1 is an obstacle, the function returns a list of coordinates which is the opt...
I am going through Elements of Programming Interview by Aziz, Lee and Prakash one of the questions is how to determine if a string can be permuted to a palindrome. For example edified can be permuted to deified and now its a palindrome.
So my first implementation is this:
