@nhgrif and I were curious about a couple different ways to aggregate a number of records based on a duplicate/common datum. Two different ideas will be shown. Any advice on all code but especially making it perform better is appreciated.
Note: @nhgrif did not write most of this, so if it's wro...
It is found that Function can return a value without using the keyword Return, function name is in same datatype as its return value. the following code will explain this:
Public Function SSNvalidate(ByVal SSN_input As String) As Boolean
SSNvalidate = (SSN_input Like "###-##-####")
End Funct...
While learning object oriented design I'm judging my own design critically. This framework should be able to print objects in either XML, or JSON, I've stubbed in a basic implementation to avoid getting into details of XML and Json parser apis for now.
So I made the Formatter be the base class....
Just wondering if there was someone out there that could offer help in optimizing my script.

This script is a total of 99 lines. Of that, 49 lines are insulting, annoying, and ironic self-congratulating comments.
In general, comments are good. They help any future maintainer (including yourself when it's been 6 months since the last time you looked at the script) to understand what ...

So I have two 2D arrays of doubles a and b, both have two rows and different numbers of columns.
a [[ 1,2,3][4,5,6]]
the list b represents a number of bins of numbers and the list is a list of numbers I'm trying to sort into these bins.
I need to go through each of the numbers in b to look ...
I've been working on our application (CQRS and DDD) for awhile now. The application architecture is well layered and thought through.
However we are having difficulties in decide where to put the below code, in such a way that it makes sense from an architectural point of view.

This is my code for 503 page.
header.php

Nhgrif pointed out a great idea: Teamwork
"I think it's probably best if the question instead has several good
answers that each address a specific topic. The result will be that no
single answer is complete, but every problem is addressed between all
the answers."
Alright, so that ...
Here's the code I have, which works perfectly
int k = 0;
for (int i = 0; i < a.GetLength(1); i++) {
for (int j = 0; j < b.GetLength(1); j++) {
//if fragment falls in bin, add it to the new object
if (a[0, i] <= (b[0, j] + binSize / 2) &&
a[0, i] > (b[0, j] - b...
I'm working on the OSCP, and Information Security certificate based around penetration testing. CLI-based tools seem to be the core of most pen-testing assignments, so I'd like to build a tool aiding in command/switch searching.
The goal of the program will to (eventually) load command line arg...
The Microsoft Visual Basic for Applications Extensibility library let's us meta-program VBA, but the way it handles (or rather, doesn't handle) getting to the actual subs and functions is clunky at best. I decided to write a few class modules to make it easier.
Considering this can be kind of da...
I've got a website where the user can log in and when they do two session variables get set:

$_SESSION['usrnam'] = $username;
$_SESSION['uid'] = $user_id;
$stmt -> close();
$con -> close();

If I find a review that seems to have a lot wrong with it, as in, I want to go through the review line by line and review it as if it had been a question, what action should I take?
A downvote is a good start, but it doesn't help explain what's wrong with it.
Comments could help in cases where ...
You are vulnerable to SQL Injections. Even when you are using Prepared statements, doing It wrong will kill you.
$sql = "UPDATE users SET " . $data[0] . "=? WHERE username=?";
This makes you exposed to SQL injections because your function is not private. You should not allow "user" access to...
I am working with a mesh of points (in 3d, although I doubt it makes a difference). The mesh is given as list of lists, each list containing the three vertices of a triangle in said mesh:
for example:
0 2 6
0 12 15
2 66 10234
I want to find the neighbours of each point, i.e. to have an array ...

I would like to get feedback on the code. It is working and can be seen here.
I welcome any kind of feedback, since I am just starting to use JavaScript. Epecially in the case of performance, there might be better ways to code.
