The goal of this calculator is to evaluate an expression with PEMDAS in mind (no parenthesis yet, adding soon). Although the program works, I want to make it as efficient as possible with the approach I used to attack the mathematical expression.
So the way I decided to approach the problem is to initially organize the... | stackexchange/codereview |
I have written a simple system to load plugins from files in Python 2.7, and I'd like to see if any of it can be improved upon.

The string I'd like to check is something like "abcSun24def". If any valid "xxxyy" (xxx = weekday and yy = day) is found, return the position inside the string. If "xxxyy" is not found, return -1.
The code works as desired, but I think it can be optimized.

Of the languages that I use, I have the most experience with C++. I am looking to sharpen my skills with C, so I wrote this small calculator program.
What I have here is a sample of how I would probably write larger programs.

One thing lead to another and eventually I wanted to know the "proper" way of writing the permutation generating function in C#. Below is my code for generating permutations. This will go into an internal library, so the calling context is really generic. Expected calling is in a single-threaded context

I want the code to perform better, especially the SetTimeout sections.

Problem Statement
A group of farmers has some elevation data, and we’re going to help
them understand how rainfall flows over their farmland.
We’ll represent the land as a two-dimensional array of altitudes and
use the following model, based on the idea that water flows downhill:

I inherited some code and have discovered that it seems incredibly inefficient. The code works by applying text formatting to the cells in an Excel file cell by cell, via this loop:

For i = 2 To lastColumn

Please help me review this code. I want to make it both accurate and more Go-styled.

I'm a beginner in Django3 and just wrote an overview function to pass on some data to the template in a context variable.
I am definitely passing a lot more than I should as I only need only a few fields from each of these variables. Also, it might not be the most Django-esque way of doing things as it isn't using Gene... | stackexchange/codereview |
