As part of a game engine I am creating, I am in the process of writing a bunch of math classes (vector2/3/4, matrix2/3/4, and quaternions to start with). Below is the code for my current Vec2 class:

I couldn't find a .NET date format type to handle dates in format I need to process, they sometimes have time zone offset with +/- prefix followed by 3 digits for the number of minutes timezone is offset by. i.e. +11:00 is written as +660
Usage Example:
GetDateTime("20161124181215.000000+660")

I'm working on a program that updates the background of an x11 desktop at a specified interval. However, it eats large amounts of my CPU just sitting idle. I know this is due to the main loop running faster than I want it to. I've used a couple shameful hacks to quell usage down to about 15% but ...
I'm doing this HackerRank problem which basically boils down to what I've written in the title. We have to find out the distance between all the odd values in the array.

Background
A VSCode extension that uses Chance.JS to generate random data types.
Concerns
My main concern is that there are 4 levels of function references that feels like a hack. From registerCommand → insertFunc* → randomFunc* → processSelection.

The problem with ?? is that if CalcNotes() returns null then it will not be cached any more. Ditto for value types if for example both 0 and NaN are allowed as property value.
Much better would be an "aspect-oriented" solution, something like Post-Sharp does using attributes and then modifying ...
I haven't played with MT programming much yet, but I'd like to lay some groundwork for what should ultimately support threads.
I have this struct that should be thread_local, and I want to lazy-initialize it on first use by copying data from a readable-writable global struct.
Would this be a vi...
You could use a 2-dimensional loop to iterate over neighbors as follows:
public IEnumerable<Coordinates> GetNeighbors(int numberOfRows, int numberOfColumns)
{
var canIncreaseRow = Row < numberOfRows - 1;
var canIncreaseColumn = Column < numberOfColumns - 1;
var canDecreaseRow = Row >...

So I have a mesh class that represents a 2d vertices.
Now I want to add a adaptive refinement feature to this mesh. So my question is How should I add this feature to the mesh class that I have. I really don't want to add this feature to class Mesh because the mesh class grows big and becomes d...
