I'm developing a plugin for Revit (a software to make 3D buildings).
The goal is simple to understand. When there is an intersection between a Wall and a Duct I create an object called Reservation at this location. I need to extract the Curve of the Ducts and the Faces of the Walls in order to calculate this intersecti... | stackexchange/codereview |
My concern is speed, since this may be used in an e-commerce website I want it to be as quick as possible. Where can I improve?

I tried to implement the shell-sort algorithm using this Java code:
// Using Pratt sequence
public static void hSort(int tab[]) {
int N = tab.length;
int k = 0;
int sequence = 1;
// Getting the final term of the pratt sequence
while(((int)(Math.pow(3, k) - 1) / 2) < N/3) {

This feels like a simple question, but I'm wondering what the best way would be to manage the elements of a private, fixed-size array.
Context: I'm making a simple particle engine, and my Emitter class will smoothly interpolate between up to 8 colors per Particle, depending on the Particle's Life value. I have that par... | stackexchange/codereview |

I took the advice I got to heart, and re-wrote it. Once again I'd appreciate any advice as to how I can improve this using best practices.

I'm more like playing and the problem I'm going to demonstrate is a learning task, so to speak, not something I really need to solve.
Imagine having a matrix of data. You chose square in it and would like to access each point on square perimeter by 1D index, like this:

In a project I have a few long switch statements which seem ugly to me. Please suggest how to refactor the following code.

This is an algorithm for finding the closest pair of points on a 2d plane by dividing the problem by half recursively, as illustrated here:
use point::Point;
type PairDistance = (Point, Point, f64);
// Divide and conquer approach for finding the closest pair of points

A follow-up to this question, this post improves on test case issues.
To restate problem parameters, a given string S is considered closed if it:
Has a matching opening and closing bracket or no brackets at all
Respects bracket nesting levels
Has no more than at least one of each bracket type in it

So I'm very much a beginner to Java and Android programming. I've worked a lot more with Python so I might have some quirks from there bleeding into my code here. I'd like a particular focus on pointing out ways I'm approaching the language and any confusing style I might be employing.

As part of my stupidly large project Concaten, I'm writing a string escaper. It's the majority of the part that turns string tokens (like "hello world" or "buncha\n\n\n\n\n\nnewlines") into the string data that they represent. It's part of the token-to-object module, hence the prefix.
