I've created a simple utility class for use in my Unity2D project, which allows a Sprite to have separate sprites for when it is facing East, North, West, or South (that's the order that z-axis rotation places them in). There aren't too many Unity-isms in the code, and the part that I'm most conc...
Here is the task itself. Cannot wrap my head around this algorithm. Could there be a more elegant solution for the task? Here is a solution (math) to an almost identical problem.

I have a routine for determining the derivative of a function using the y-intercept (B) to infer the finite difference step (h). Instead of directly using smaller and smaller h, we can solve for the slope m in y=mx+B with a given B. That B represents a specific h after some substituting and sim...
I have a text file with the following three line pattern with blank lines in between. My script sorts alphabetically by each person's last name and preserves formatting.

For a while now, I've wanted to write a stack-based "Turing-tarpit". This is the perfect excuse to learn ruby, which I have never used before. So I wrote Brain-flak.
The language only uses these characters, ()[]{}<> in various contexts. Here is the interpreter:

Check this line of code. The simple idea is to print the input in a different order.

The Gilded Rose Kata is a refactoring challenge, in which some frankly disgusting code is thrown at the developer, and they're told to make a small change to it. For reference, the (truncated) requirements and the original code are given here:

I am getting the number part of the container ID that the button is in. Now I am wondering if I need to create an array using split and then put this number in a variable, or if there is a more efficient way to get it.
.match() also returns an array, so this is almost the same as using split.
