So I was making a library program for trying to practice C++. I wanted to use a vector to store all the books. The books being a struct to hold the general things the books would have. Which something like this:
struct Book
{
string bookName; // book's name
string bookAuthor; // book's...
I tried to make enigma, but ugh. I don't know what is happening.

I'm having trouble programming a GUI in python. It turns out that when compiling the same code without a GUI, everything works fine. But with the GUI, it stuck at one point in the code. The code starts as follows:

I am making a flashlight plugin for macOS.
Here is the main code, plugin.py, the method results gets called first and is passed a dictionary like this for example:

And I try to parse the time span given and activate a macOS alert later.
Anyway, I'd appreciate any po...
Given a decimal number I need to convert it into binary
Given a binary number I need to convert it into decimal
After the conversion I need to perform some operation on it (for example, addition). Also I need print the result with a specified width.
To accomplish the above I wrote the followi...
This is a follow up of the question I posted previously here.
I made some changes, based in the answer by MikeMB, making use of asynchronous calls (with std::async and std::future), instead of std::thread as before.
Here is the code:
monte_carlo_pi.cpp:
#include <iostream>
#include <iomanip>

Numeros, the Artist, had two lists A and B, such that B was a
permutation of A. Numeros was very proud of these lists.
Unfortunately, while transporting them from one exhibition to another,
some numbers were left out of A. Can you find the missing numbers?
Notes
If a number occ...

I've written a basic implementation of a singly linked list in Scala.
Would appreciate any feedback and improvements (especially the remove() method, I feel like it could be implemented better).

I was getting a NoSuchElementException when parsing my double so I had to refine my code to validate the input. Is there anything you recommend?
Code prior to the validation:

A simple selection sort functions in R. Just for practice.
Given the choice of algorithm and tools I wonder what can most easily be improved about the functions.
NB. I wanted to keep the first function as elemental as possible.
