I want to represent the "status" of a thing and use a static representation to refer to it along the code. The best representation for this would be an enum, but I need polymorphism, so I came up with this:
public interface IStatus {}
public abstract class StatusBase<T> : IStatus where T : Stat...

I want to run some compute heavy tasks on a separate process, so that they don't hog the GIL and I can make effective use of a multi-core machine.
Where those tasks are pure functions, I'd just use the provided multiprocessing.Pool. That, however, doesn't work as well for tasks that...
I am Python student in the very early stages of learning.
Today I learned about Recursive Functions, and in an attempt to try it I wrote the following code. The goal was to eventually trigger a message by checking for a boolean return, but the return keeps coming up as None.
I'd like to add tha...
I am a novice of Python and I am trying to understand how to use OOP paradigm to improve my scripts. My scripts usually read some data from a formatted csv file and perform some numerical analysis. Here is a short example:
SIMPLY SUPPORTED BEAM
NNODES <NNnodes><Node,X,Y>

1,0,0
2,1,0

So I am attempting to do this programming task:
Here is my current "code":
matrix fireForecast(n, d, start)
{
M = [n-1][n-1];
M[start.x][start.y] = 0;
burningPoints = [];
burningPoints.addPoint(start);
for(int i = 1; i < (d+1); i++)
{
setWindType();
for...
Here is my very first code which fetch data and add it to MySql. Please review my code and let me know if I'm on the right path. Is there anything I can improve?

In Java, I use a LoadingCache which offers weakKeys
and I need something similar in Typescript, so I wrote the following:
function loadingWeakCache<K extends object, V>(loader: (k: K) => V) : ((k: K) => V) {
const cache = new WeakMap<K, V>();
return function(k: K) : V {
let v = ...
My goal is to get a list of related setnteceIds in order of most repeated.
In my database I have stems(Words):

| Good | [1,123,45] |
| Morning | [23,2436,12312] |

How would you in a pythonic manner write a function that returns the common substring found at the beginning of a set of strings? This is my ugly attempt:
def common_start(s):
l = len(s)
if l == 0: return None
elif l == 1: return next(iter(s))
else:
i = iter(s)
start = next...
I was working to upgrade some code to C# 8.0 and came across an interesting pattern with default parameters and non-nullable reference types. I'm working if it's clear enough to the caller.
Given this pre C# 8.0 code,
Task FooAsync(
Bar bar = null,
CancellationToken ct = default)
{
ba...
Here is a custom Random<T> class which could be used as:
Random<int> random = Random<int>(10);
int zeroToTen = random.Next();
I also made it seedable through the ambient context, so the following is observed allowing to potentially have Seed anywhere above in the call stack to simplify unit te...
