I wrote my first virtual machine recently, and I need to know what I should change in my next vm to make it an actual vm. I created this one as more of just an interpreter with a instruction set you would see in assembly. I did not create this using many things a vm should have, and I put it toge...

Here is a project that I have been working on for the past few days. I have used the SFML library in C++ to make a flappy bird game of my own. I made this as a step towards learning GUI in C++. The program is Object-Oriented as I believe this made it a little easier to maintain. Although this ...

I have a react native native app and I am fetching the state of the toggle buttons from an API and then putting them into redux state. I do not like the way I have implemented it cause it seems very messy and was wondering if anyone would have any suggestions on how to refactor the code. Below is...

This is the follow-up question for A Summation Function For Various Type Arbitrary Nested Iterable Implementation in C++. Besides the summation case, I am trying to implement a Max function which can find the maximum value in various type (comparable) arbitrary nested iterable things as the furth...

I have a small blog backend in Rust with Rocket and Diesel on Postgres. It reads and writes to and from the database fine, but to get to where it is I used a lot of clone() calls on strings. I feel like it could be written more efficiently with lifetimes, but my grasp of lifetimes in Rust is quit...

Fermat's last theorem states that there are no natural numbers (1, 2, 3,…) x, y, and z such that x^n + y^n = z^n, in which n is a natural number greater than 2. Here is the code, you can ignore the first 2 functions. def diff(n, mid) : if (n > (mid * mid * mid)) : return (n - (mid * ...

I have some directories with artifacts in them, and I want to clean them up by deleting them. The requirements are: Keep the 3 most recent directories Keep only one snapshot folder Keep only one rc folder Delete everything else The print commands should be written to a log file for posterity Th...

I've ported a C++ approximation search algorithm to Python. Unfortunately, my Python is a bit rusty, so this could probably use some (read: a lot) of cleaning up. Additionally, I remember a better way of working with instance variables than using self repeatedly, which I find a bit cumbersome. I ...

I was recently set Task 2 as seen below and I realise someone answer the question on this site here but I wanted a fresh opinion TASK 2: Allows two players to enter their details, which are then authenticated to ensure that they are authorised players. Allows each player to roll two 6-sided dic...

I recently came across the need to allow consumers to prevent further execution of methods and I utilized an event driven system that allows the consumer to specify if the execution should cancel. I've tested it in a multi-threaded environment and everything is working as expected so as a simple ...

Here is the example int a = 5; int c(5); I hope the syntax highlighting works for you, if not then the way a and c are highlighted is different, shouldn't they be highlighted the same way? c has the same highlighting as a function would have (bright orange)whereas a has no highlight.

When using Arc<tokio::sync::Mutex> and passing an arc into double closures, is it good practice to clone the "challenge_ref" here. Without the clone the compiler will complain about "cannot move out of challenge_ref a captured variable in a FnMut closure". this is in a hyper http server were "ser...

I've been playing around with the coroutines implementation in gcc 10.2.0 (Debian build) based on the sparse documentation at https://en.cppreference.com/w/cpp/language/coroutines . The target, for now, was to see how to use the functionality to enable creation of Python-style generator function...

Consider a function that accepts a Callable as a parameter and a dictionary of arguments as another then simply applies the parameters to the function: def call_f(f: Callable[..., int], p: Dict[str, Any] -> int: return f(**p) The function will often be something like a random number generato...

I have a young friend of mine who is starting to learn python in school and asked me to give me a little assignment (I am in no way a teacher nor a python expert but I accepted). At first I thought it would be fun to start with a bit of parsing for the operation's input, like : Enter your operat...

I'm currently making a game using C++. I eventually needed a logger, but I wasn't satisfied with any of the existing solutions. After a while, I wrote my own header called log.h: #include <iostream> #include <iomanip> #include <string> #include <ctime> #include <fstream> #include <sstream> clas...

A common parameter parser for Python seems to be argparse. Its parameter keywords are indicated by "--keyword", such as "--nogui" or "--debug". However, I want to use a multi word argument such as "output name" and "output dir. parser.add_argument("-on", "--output-name", help = "Custom output fil...
