By profiling my application (written in C#), I found that the bootleneck of my application is the function below. In particular it will be executed by a lot of entities (monsters) in a game, that will go onto a smartphone.
The graph is the model for this type of grid: (the final one is 25x45)

I was building a rails web, and used form object to separate the validation logics per form.
I had to find_referral_code twice in order to store the user_id of referrer. I wonder how I can improve it.

I'm writing a generic import\export program to import\export Stock and Sales Orders from a number of legacy accounts systems.
I'm loading the correct concrete classes using a factory pattern, so the idea is that I can just swap between different accounts systems for importing orders, etc.
I can...

Here is the problem I am trying to solve:
Using dynamic arrays, implement a polynomial class with polynomial addition,
subtraction, and multiplication. Discussion: A variable in a polynomial does nothing but act as a placeholder for
the coefficients. Hence, the only interesting thing abo...

Whilst for someone like Jon Skeet, making a simple script here and there might take a few minutes to type out, for a beginner, this might take a few days to even understand.
The close voter must remember that people come here to seek review of their code. Whether or not the code is complex is an...

When I want to try a new language, I first try to write a fairly basic sieve of eratosthenes project in said language. This is a very simple algorithm, with predictable results, and can even be optimized somewhat to compare versions of different languages' compilers. I've done this in (chronolo...
Does any developer like using std:: everytime with the stl containers.
No way !! ( Is it a good coding practice, neither).
There can be several ways to eliminate such usage.
Ideally in bigger projects, people follow a strategy of comman.h
comman.h
#include<iostream>
#include<set>
#include<map>
what would be the best approach to rewrite this bit of coffee/javascript to save one .on function or save variables.

It looks like:

/*
* The following iterative sequence is defined for the set of positive
* integers:
*
* n -> n/2 (n is even) n -> 3n + 1 (n is odd)
*
* Using the rule above and starting with 13, we generate the following
* sequence:

* 13 -> 40 -> 20 -> 10 -> 5 -> 16 -> 8 -> 4 ->
