It seems to me that if you're going to do this, it's worth avoiding all those substring calls, since they're pretty slow. It ends up almost simpler without them anyway.
private static boolean isPalindrome(String pal) {
return isPalindromeImplementation(pal, 0, pal.length());
}

Last time I made a website using PHP, I didn't know of PDO, so someone dropped all my tables. I think I've made an improvement now. I'm sorry if theres a lot to go through, but I want to make sure its safe (most importantly) and also using the best practices.
Here are some snippets.

My manager says we don't need to salt our passwords because people are not likely to use the same password because they all have different native languages, in addition to the websites they are active at. What is the best counter argument to this?

int num = 0;
int negative = 1;
if(s)

if(*s == '-')

negative = -1;

In browsing the site today, I came across a question about doors somewhat related to something I’ve been wondering for a LONG LONG time:
Why don’t we remove all door handles and let doors open both inwards and outwards?
I have lost count how many times I failed to open a door the first time I g...
The major concern: I think these functions:
saveAnalysisToPlainText, saveAnalysisToJSON, and
loadAnalysisToPlainText, loadAnalysisToJSON
are redundant and can be improved. But I don't know how to start.
Minor concern: I see a possible redundant function:
There are two setStructure functions.

This usually is an issue with preconfigured IP's.
as mentioned in another answer, the two PC's need to be on the same network. This network is defined by the combination of the Subnet Mask and the IP-Address.
A short explanation. As you probably know, numbers are stored as zeroes and ones in ...
I made this UUID generator which I believe doesn't follow the methods used to generate UUIDS. I don't believe this is the correct way, but I just wanted to check in.

Ultimately, this program is going to be cons...

The code you post has to work and be yours. Debugging things is not the purpose of Code Review. Beyond that, pretty much anything is fair game. So, yes. You can post such a project.

I have been working on a small game called apple picker, it's text-based, and relvolves around picking and selling apples. Unfortunately I've been using global variables for this whole thing and it's starting to get a bit ugly looking. Is there a more efficient way to do this than using global va...
I am working through more tutorials on Design Patterns and came across the Abstract Factory Pattern. I extended it out a bit (the example that is) and want your opinion:

Quick question, Now further in my career I have found that I am still sticking with some of my bad coding techniques, such as Coding directly into the Event (such as the _ButtonClick event), instead of directing the code to create a new object out to a separate class.
This is causing spaghetti-...

Proposal: Is my code right is already amply covered by Stack Overflow and Code Review.
And what wouldn't be covered thereon, are most likely homework-type questions, which are typically frowned-upon in the "give me teh codez" format.
Let's go to the data
I've been a lurker, not a participant, for most of the time since I joined. So I think the best thing I can contribute to this discussion is use of my data-wrangling skills. Here are a few interesting queries. And bear with me, this post is beyond TL,DR
