I have heard that patterns are something that an observer would see after the code is written, not something that a developer uses to design code, but I have also heard it the other way around.
So, getting to what Vogel612 concluded, you Don't have a Singleton, but it does what you need it to, s...
My colleague created this sql to handle certain user selections which are based on an on/off bit flag. The goal is to identify those individual bit flags with a specific integer which will be used in a later SQL to group specific types which the flags relate to.
What would be a more elegant way...6

XKCD inspired... I was reading the comic and went "well, where do they go when it rains?" I know that when it rains you usually don't see any birds flying through the sky.
I imagine they hide in trees. But what if they're busy trekking to warmer lands? They can't just keep hiding until it's dry ...

Just looking for some feedback for one of my models I have for a project. I'm pretty happy with it but I was wondering if anyone had any optimization suggestions.

$this->db = $db;

Take a integer as a input and replace all the ‘0’ with ‘5’.
For example:
102 - 152
1020 - 1525
(Do not use any array for replacing the '0' to '5')

So let's start by describing the problem. This was a previous homework assignment i was required to do. While i did the assignment and turned it in for credit, I am not completely satisfied with the result I have. The rule for the assignment is it HAS to use backtracking and HAS to let the user p...

I'm unit testing some webpages in Python 3.4 (Django 1.7), and I'm trying to figure out how to best isolate the portions that need to be tested, without imposing on the webpage's content or format. It should also be as clear as possible to the webpage editors what's going on, so they don't inadve...

In my application, I have a message dispatcher. Each message gets relayed to a dispatcher thread.
In some scenarios, I can get two responses from the third party in the same millisecond:
An "I received your message" ACKnowledgement
"My response to your message" RESPONSE
When I get both mess...

I'd put the Eigen headers below the STL headers. Also, <math.h> should be <cmath>, the latter being the C++ library incorporated into the std namespace.
You can define main() below the other functions, allowing you to save a bit of room by eliminating the function prototypes.
You don't need tha...

The following class implements a buffer which captures fast changing datapoints or frequently raised events and dispatches them in batches. It will asynchronously call a processing function for the buffered items under any of the following conditions:

Can you please suggest more elegant and eloquent ways for this problem? (Perhaps better ways to represent a graph with vertices and edges?)

This is for an Android (via Cordova/Phonegap) game project. My goal is to be able to provide a "promo code" that will allow anyone to unlock the game for free, but I want to limit each code to only work for a day and I don't want to rely on a server side component to validate the codes. The sol...
LOLCODE: 109 (105 with "correct" spelling)
LOLCODE is not a great language for golfing, especially since you lose all the beauty and expressivity when shortening the code.

I'm implementing a communications protocol in an embedded system and the protocol uses a subset of the ASN.1 BER (Basic Encoding Rules). Because it's going to be running on an embedded system, it will not be using any of the following:

I am trying to write the simplest to understand code possible, each function has documentation and examples and I tried to use the best style possible.
The individual methods are simple and easy to understand.
The docstrings are especially great, they are fantastic help for the reader.

I have recently been refactoring some code in an effort to improve the exception handling, particularly to aid in improving the level of information given to developers during development. However I am worried that I have started down the wrong path.
For example we were getting complaints that t...
I'm trying to account for the fact that my program will contain calculations such as:
v(t) = w ∗ v(t−1)+ c1∗r1∗( pBest − x(t −1)) + c2∗r2∗(gBest − x(t−1))
where v, x, pBest, gBest are vectors (std::arrays). I'm a little worried if I make correct use of the move semantics.
Here's the relevant ...
Currently, in a utility class I have methods like so:

int nextNumber = UtilClass.getNextAvailableNumberAsInteger(currentObjects, null);
return UtilClass.formatNumber(nextNumber); //formats number as string
}

I've been tripping on this one for awhile. The actual logic is even more complex, but simplifying it this far is sufficent. (For those who care, (which does not include the vendor!), the product is an Arcsight Smart Connector)).
I need to convert Boolean logic like this:

That's Last Week, Month-to-Date, Season-to-Date, and Year-to-Date sales.

I am trying to create a form of Buffered Input to see how easy it would be to implement, without the use of Rx or any other library. So I came up with the following class:

Whenever I write a loop, I always use closure if it's appropriate by way of a self-executing anonymous function. I will typically write my searching loops as follows:
var i = 0, length = myArr.length,
fe = null;
for (; i < length; i++) {
if ((function (el) {
if (el.searchCon...0
