So let's start at the beginning before we head jump into my code mumblings, Minecraft is a game which also has multiplayer capabilities. You need to have an account (which needs to be verified) for playing on servers. The authentication procedure looks like this:

According to Donald Knuth in "The Art Of Computer Programming", the following is how to find the greatest common divisor of two positive numbers, m and n, using Euclid's Algorithm.
Divide m by n and let r be the remainder.
If r is 0, n is the answer; if r is not 0, continue to step 3.

Here is a simple recursive solution in C, this is pretty elegant.
Note* I used ternary operators for the boolean statements, Type it in on google for more info and check out the wikipedia page for ternary operators in C!
#include <stdio.h>
#include <stdlib.h>
// recursively computes gcd
int gcd...
Building a 'card' database: I'm simply learning to take input data and store to database. Incorporating json, pdo, sql, and enforcing my general coding skills through php, hopefully.
Here is the script-
$query = $dbh->prepare("SELECT * FROM " . $table);
$query->execute();
$result = $query->fet...
Ok, hello. I made a code to make a calendar, and it does work, BUT I believe it's extremely inefficient. I think I have way too many else if statements:
import java.util.*;
public class MyOwnCalendar {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.i...

This isn't necessarily a bad use of the : instruction separator, but it did surprise me. Actually, I'd even give you a star on that one:
Dim Age : Set Age = Parameters.Item( Bookmark , "Age" )
Pretty much any other use I can think of of the : instruction sepa...
logic currently has 17 questions. I don't see what they have in common. There is no tag wiki to clarify what it means or when it should be applied.
Yes, we have a badcode tag on Stack Overflow. I didn't realize it until just a moment ago, either.
There's like sixteen questions, most of which can be reasonably retagged without any loss in quality...but I would propose that this tag be terminated with extreme prejudice.
This is the main project my Raspberry Pi is dedicated to right now, so I figure I can add my two cents. Keep in mind this project is still very much a work in progress.
I chose to use the C programming language for this project exclusively on the Raspbian OS, and that may have affected some of ...
This JavaScript code gets the average loudness of a sound.
//rest of the audio code is omitted
analyser.getByteFrequencyData(freqByteData);
sum = 0;
for (var i = 0; i < freqByteData.length; i++) {
sum += freqByteData[i];
}
avg_loudness = Math.floor((sum / freqByteData.length));
}

A phone number may contain formatting like "(123) 456-7890" or 123-456-7890
Is this regex sufficient to remove all formatting from phone numbers :-
fromNum = fromNum.replaceAll("@\"[^\d]", "");
I've some classes (Derived1, Derived2, etc.) derived from class Base. All of derived classes have a following methods (reduced sample):
void Derived1::handleTimer(const StatusType &st) {
if (!st.isOk()) {
SetTimer(10); // wait for 10 seconds;
AsynWait(boost::bind(Derived1::handleTimer,...

The specific issue is this: I am writing to a file and want to output a new line after each line written. If I use a normal loop without any further checks, this will create a blank line at the very end of the file for no reason. So I need to do this every time except the last one.
Despite the...
this is another script that is used as a token to extract information from a 3rd party application, the application does other things in the background that I don't specifically know about.
this code does work inside the parent application and produces the expected output.
Is there a nicer w...
