The online book Game Programming Patterns briefly describes the use of the command pattern to handle input in a game. I've attempted to write my own "one size fits all" input handling system based on the command pattern, as shown below. Is this a correct implementation and use of the command pa...

I found this pseudo code for KNN algorithm over here. void classify(int k, Point[] querySet, Point[] trainingSet) { // Loop 1. foreach (query in querySet) { // Loop 2. foreach (training in trainingSet) { // Create a fixed sized sorted map of length k, // where we map the ...

This is a script i made for testing a simple operating system. It assembles the source and creates a boot image, then It automates the configuration of a Virtual Box machine. #!/bin/bash OS_NAME="hello" MEMORY_SIZE=8 build_main () { # remove old files rm -f $OS_NAME.bin rm -f $OS...

Follow up question for: Conditional row count across 4 tables After getting some excellent help from 200_success, i managed to output the SUM() total of my query using the following code: get_results returns standard mysqli_assoc_array: $row = $this->get_results($query); $sum = $row[0]; fore...

after some free ASCII flowchart drawer started charging money, I decided to write my own. Salient features are that you can draw a box (mouse down, mouse move, mouse up), then control B it will draw a box. Copy/Paste, Undo, Redo, click anywhere and type are all working features. I pasted the main...

I am parsing an unstructured text file and am using regex to extract certain pieces of data. I compile all of my Pattern objects beforehand and then use them throughout the parsing. So for example say I had 2 patterns: Pattern namePatt = Pattern.compile( ... ); Pattern itemPatt = Pattern.compil...

I have the following function to compare a string with a wildcard string (containing ? and *), as C# doesn't seem to have a builtin function to do it. /// <summary> /// Compares wildcard to string /// </summary> /// <param name="WildString">String to compare</param> /// <par...

We have a decent selection of language and technology tags, but we also have many meta tags, such as refactoring. A meta tag, at least on here, specifies the OP's request(s) in a review, and not much else. It could especially become problematic if the OP has many requests and tries to apply as ...

The following is a readable SQL to Eloquent that I have created that WORKS. The down side is that it looks more like a 1:1 with SQL and I dont think i'm using the full potential of Eloquent. I thought of using Scope queries to shorten it - but for some reasons the selectRaw prevents it (due to mu...

Looking for code review, optimizations and best practices. public class FindMiddleStack<T> { private Node<T> top; private Node<T> middle; private int size = 0; private static class Node<T> { Node<T> left; T item; Node<T> right; Node(Node<T> left...

I have a working function that may be optimizable. Currently processing 4 objects gives me 0.0459822 for the elapsed time in seconds - used for testing purposes. Once implemented into the app I will be checking > 1000 objects at a time. The format of the fd.dataTime and the other TimeSpans are ...

Design a Data Structure SpecialStack that supports all the stack operations like push(), pop(), isEmpty(), isFull() and an additional operation getMin() which should return minimum element from the SpecialStack. All these operations of SpecialStack must be O(1). To implement SpecialStack, you sho...
