What are the overall pitfalls with a GUI resting on a netty client?
I want to ensure that the netty client which is passed to the GUI doesn't run into or cause any synchronization or multi-threading issues. I'm not exactly sure of the pitfalls.
I'm finding my way with netty, and haven't had th...
I am trying to create an outline of what a character is in a game.
Then I want to create 10 different characters and compare their stats at different levels.
I am creating a class called Character that looks like this,

does anybody know why the following code:
foreach ($_POST as $new => $new_val) {
foreach ($info as $old => $old_val) {
if ($new == $old || $new_val !== $old_val) {
$change_log[$old] = array("old" => $old_val, "new" => $new_val,);
var_dump($change_log);
...
Is this code correct?
It appears to work in g++ 4.8.3 and clang (bcc64), however appearing to work is no guarantee of correctness :)
The aim is to be able to replace a call to a member function:
void Master::go()
{
std::string s;
func(s); // func is a member function of Master

First off, I am new to codereview. Please let me know if this question and the practice of pasting my code in its entirety is considered a good practice here.

I am creating a bookmarklet which requires jQuery. So before I execute the main javascript code of the bookmarklet, I have to make sure jQuery has been loaded in the page. So far I have come up with the two following approaches:

I have this Objective-C code for use in an iOS app that makes a 'bar' on the screen, with a red exclamation mark that flashes in it at random places. Here's what it looks like:
Header file:
#import <UIKit/UIKit.h>
@interface ESFlashingErrorBar : UIView
@property (nonatomic, strong) NSArray *...

I'm just a beginner myself but I feel like I can point out a few things in this code.
First, I would add some white space at the top of the file here:
#import "ESFlashingErrorBar.h"
#import "ESThemeManager.h"
@implementation ESFlashingErrorBar
#define kNumOfPoints 7
int lastFlash;

Is using a static variable in a lambda function ok, or considered a bad practice? The code below works as intended (fills a vector with consecutive numbers).

{
vector<int> vec(100);

I have a problem with my multithreaded application. I have this method in a thread that interrupts all the current threads running. It does this by storing an ArrayList of these threads.

I created a loader animation for an android app. A simple 3 dots loader.
Is this the correct way to animate by using TimerTask ?

int highlightColor;

Animation is the process of creating a continuous motion and shape change illusion by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon. Animators are artists who specialize in the creation of animation.
Animations can be recorded on either analogue media, such as a flip book, motion picture film, video tape, or on digital media, including formats such as animated GIF, Flash animation or digital video. To display it, a digital camera, computer, or projector are...
I thought up a function that provides types with InputStream and OutputStream:
trait Format[A] {
def read(i: TypedInput): A
def write(o: TypedOutput, a: A)
}
trait TypedInput {
def i: InputStream
def reads[A](implicit f: Format[A]) = f.read(this)
}
trait TypedOutput {

I created an Observable class that allows me to subscribe to a wrapped value. The implementation looks like this:

In Ruby I do not like to use while-loops. I was wondering how to generate a "squared sequence" (e.g., squares the first input, then squares the outcome, et cetera) in a more idiomatic Ruby way than this one:
value = 2
while value < 10000
puts value = value**2
end
# => 4
# 16
# 256

I've decided that I want to take a stab at test first programming. So, before I tackled writing an isPrime function, I wrote this unit test. It's my first and I'm not sure I'm doing this right.
I was thinking that I might want to extract the loops to just two methods that I would pass an array t...
