In this code I have taken an image as input and output the same image. As far I know if two images are same then their PSNR value will be inf. So I calculate their PSNR value using MATLAB but it shows 48.05 that means those image are not same. But I read and write the same image, why this is happ...

I've solved the Project Euler Problem #4, but I'd like some tips as to how to make this more efficient. I am a beginner to Ruby, so please be nice about the stupid stuffs (but still tell me about it).

n == n.to_s.reverse.to_i
end
end

I am currently reading an algorithms book and I read on the insertion and merge sorts. I implemented the merge sort in C++, The first function MERGE is responsible for the merging of the two subarrays part and the function MERGE_SORT is the actual algorithm. I am interested to know whether or not...
I've solved this question, but have a small question. In the while loop we check if (temp->next != NULL), why wouldn't work if we check (temp != NULL). Isn't it the same, both checks will get us to the end of the linked list? Also any code review is appreciated!
You are given the pointer to t...
I am making a kind of form, and I want the user to be able to enter a dynamic number of string inputs. The idea is that a single TextBox will be displayed, and once the user has filled that out, they will be able to add another one, and repeat the process as they keep filling the text boxes. Once...
A big Shout
Reference types by default have values of null e.g string and object.
object o = null;
string ipAddress = null;
Please don't do the above
object o;
string ipAddress;
I have a variable containing a string in this format "Size-XS|Size-XL|Color-Red|Color-Green". When i process it the final result is "Variations: Size: XS, XL, Color: Green, Red. The code for this is like below.
$variations = explode("|", $search_db_row['variations']);
foreach ($variations as $v...
I have a Microsoft CRM 2016 plugin that checks if the user that triggers an update message has at least one of the required roles, when the updated record is owned by a specific user.
Here's the code:
public class CheckIfOwnedByPool : BasePlugin

public CheckIfOwnedByPool(string unsecure, ...
I spent the last two days getting a ribbon animation to work with divs so that I can later add li link elements to them to act as a menu. I used the progess bar animation code as inspiration from w3schools. The animation works great, only issue is that the code is very un-DRY. I tried to simplify...
As the moderator involved, I'm obligated to respond.
This specific question
I have to admit, it was a complex decision process for me, with many factors to consider.
Code Review is a place where programmers post their code for feedback…
… subject to a condition that the code must work as inte...
I create multiple BackgroundWorker within a for-loop and each of them needs to know a special value. To simplify, it is just i in this example. When the BackgroundWorker is finished, I need to read that i again. I thought of subclassing BackgroundWorker and creating a class MyBW for that purpose ...
I am trying to create simple app, where I need a pagination for my JTable. I want have there buttons with number for all "pages" in my JTable. I have code here:

I currently have a list of lists like
L = [['E2', 'C1', 'A1', 'B1', 'C2'], ['C1', 'D1', 'A1'], ['C1', 'C2']]
My aim is to compare L[i] against L[i+1] to make sets. For example, L[2] is a subset of L[0] so I would eliminate it. My two different list will be L[0] and L[1].
For this, if I can som...
I'm starting with implementing a TCP/IP stack for embedded systems which will be done in C++ and I've found I need a good way to work with protocol headers involved (e.g. ARP, IP, TCP). Major requirements are:
Portable, C++(11) standard compliant (e.g. no structure packing, independent of CPU e...
Currently I am writing an SDK for use with an existing API. Primarily I am seeking input on whether the way I am writing this code is efficient and if not what steps can I take to streamline the code. This SDK will be imported and used in Android so I am trying to use libraries that are already i...
What should we do with:
Short answers (for example, "I suggest you use [hyperlink to this standard API] instead.")
Code-only answers (for example, an improved version of the code in the OP)
Such answers could be improved (e.g. by adding an explanation of why the suggestion is helpful).
Is it...
First thing, let's clean the comments and indentation, because what you have right there is just unreadable.
First, fix indentation...

I have a session authentication script and it works, but I can't find a way to eliminate the redundancy where the two database queries are. One checks if the cookie has a corresponding entry, and the other retrieves data based on the entry.
$con = new Database();
if(isset($_COOKIE["session"])) {...
I knocked out a dice roller in 2 days. I think this is the first coding project I've ever actually completed to a degree where I'm not embarrassed to post it.
This is my first time working with objects, sets, and recursion. It took a lot of trial and error and it's not the most stable (bad synt...
