June is about to end. Summer's here (well, if you're in the northern hemisphere, that is.. otherwise, ... yay, winter!), and with it, vacations. We need a new community-challenge.
Let's play. I mean, let's find a game to play.
The game...
Has to revolve around reviewing code, or posting code ...
Inspired by Extensible and testable FizzBuzz I have decided to write my own implementation, partially based on my own answer and on the other answers.
First a warning to all of you: Never make such complicated code for such simple jobs!
Now the basic requirements of the code:
Should be capabl...
The user enters coefficients into input boxes on a form, called GetFunction. Upon clicking an 'OK' button on said form, the input is validated using TryStrToFloat. If all the input boxes are valid, CreateGraph is called. As soon as an invalid input box is found, CreateGraph should not be called a...
I have written the following meta-tags for SEO, please let me know if you think this could use any improvement. I have used this article to help me put it together. I have left out the page content on purpose, if you wish to see it I posted it here on CR and on Github (note the following updates ...
I am working on a project with Notepad++ and Komodo Edit that will compile NP++ documents using Komodo's UDL extension editor without operator overload. I cannot complete the build because Komodo does not read NP++ syntax.
Any suggestions?
I just finished the Project Euler #7 in Swift, and since there is not any version yet on Code Review, I would like to have some comments on what I did to try to improve it.
import Foundation
func isPrime(number:Int) -> Bool {
if number == 1 {
return false
}
else if number <...
Most of the Rx Compelling Examples™ load and store data locally which I don't find that Compelling.
I spent some time coming up with how to best perform the following actions but want to make sure I am not Doing It Wrong™.
Here are the cases I am trying to solve:
Load data from cache and remo...
I am using this code from this link http://playground.arduino.cc/Code/PCD8544 but I do not understand some things and would like someone to help me with.
What is happening here on this part of code?
static const byte ASCII[][5] =

{0x00, 0x00, 0x00, 0x00, 0x00} // 20

I had a school project to solve, which I did. The basic focus of the project was to create the simpliest code possible to solve it, which I did it. This topic was created just to ensure, if I wrote the code correctly.
The problem is the following.
We have declared a dynamic array which will tak...
I started learning Python a couple of weeks ago, and to test my new knowledge of Python, I decided to use Pygame to code a random walk terrain generator.
# Basic random walker program
import random
import pygame
import sys
# Screen width and height
WIDTH = 900
HEIGHT = 900
# Initalize pygame...
It's quite good. I can only slightly simplify it:
NR==1 {print; next}
{
label[NR] = $1
for (i=2; i<=NF; i++) { sum[i] += $i; val[NR,i] = $i }
}
END {
OFS = "\t"
for (nr=2; nr<=NR; nr++) {
$1 = label[nr]
for (i=2; i<=NF; i++) $i = sprintf("%.2f", 100*val[nr,i]/sum...
I have worked for a few hours and this is the result:

the thing is when It has more than 1000 particles It becomes laggy, all the code is written in javascript, what should I improve?
I do not know JavaScript, but as I was reviewing an HTML/CSS/JavaScript question, I ran the JS through http://jslint.com/ to see if there were any obvious errors, like missing semi-colons. The JS in the question used 2-space indentation, and the validator told me that JavaScript should use 4-spa...
I've just done Project Euler question 10: Find the sum of all the primes below two million.. I get the correct answer and it takes about 3.5-4 seconds to run.
I tried to use the Sieve of Eratosthenes to find the solution, but am not sure if my solution is using the method correctly, or if it cou...
The code is as follows:
module Main where
isDiv :: Integer -> Integer -> Bool
n `isDiv` k = n `mod` k == 0
fullyDiv :: Integer -> Integer -> Integer
fullyDiv n k
| n `isDiv` k = fullyDiv (n `div` k) k
| otherwise = n
intSqrt :: Integer -> Integer
intSqrt = floor . sqrt . fromIntegral
...
This is a short answer to your question about line 81. Instead of all the False, you can do this:
add_village = random.randint(1, n) == 1;
where n is how many false you have.
random.randint(1, n) generates a number between 1 and n, and == 1 checks if it is one. It has a 1 in n chance of retur...
Is there a way to write the code below in a shorter version? What it does is, if the checkbox is clicked, it will be added to the total, if not, it will be deducted or ignored. (the total checkbox I have in real is 25.)

function tblcheckboxes(){
var a, b, c, d, e, f, g, h, i, j, k,...
To celebrate an important event, I hastily cobbled together an HTML canvas-based animation.
A few concerns I have include:
Performance: Does it run reasonably smoothly on most modern machines? How can I make it more efficient?
Portability / Compatibility: Does it work correctly on all modern ...
I feel like I'm repeating a ton of code here and there's got to be a better way to do this but am just completely spacing right now. I basically have an else if clause that if their conditions are met repeat the same code but I'm also repeating the same code in the else statement along with a few...
I agree with seand, but I'd also point another facet.
Why doesn't the poster edit their question to put the code in?
They don't want their code in that question, (seand's case) in that case we shouldn't override their wishes.
They never came back to look at the question, and so don't see the c...
No. We require the code to be contained within the question, for the following reasons:
To avoid dependency on third-party hosting services. These links tend to go away after a while.
To prevent review requests of huge projects.
To make it easier to see the code and so it can interest more revi...
I am trying to learn kTurtle (slightly different from Logo) so that I can help my daughter learn to write code. I have decided that I would write a program that would play Tic-Tac-Toe with a user. So far, all I have is the Game board, and I make it more than just a single board to add to the in...
