I recently wrote a Fibonacci program in python, and one of the answers mentioned an Infinite Sequence. I decided to implement a Infinite Sequence in Java, as I am not that experienced in Python.
Code:
import java.math.BigInteger;
import java.util.LinkedList;
import java.util.List;
public class...
I was looking at the memory impact of a simple LINQ query and noticed that the LINQ query created 2 extra objects of types Enumerable+WhereListIterator<Int32> and Func<Int32, Boolean>.
The code used is this:
static void Main(string[] args)
{
// Setting baseline snapshot
var list1 = new...
The reason the lambda is not GC-ed is the structure of the lambda itself:
item => item > 5000 && item < 7000
This lambda does not capture anything, meaning that it can be compiled once, and reused forever. C# discovers this, and takes advantage of lambdas like that by caching them statically t...
Recently, I had some several coding test for getting a job as a Java Programmer but I failed.
I do not know what is the reason why I failed.
Please give me some advice to improve my code.

The MSDN page on ByRef and ByVal keywords isn't very helpful; unless I somehow skipped it, they're simply being referred to as "keywords" everywhere.
One of the main contributors of the Rubberduck project is working on a very cool Encapsulate Field refactoring, and the UI is coming along pretty ...
This is the main.c file for Khronos, a personal project of mine. This is basically where the whole program is setup, run and then quit. I'll post the short summery of what this file does from the README.md:
How Khronos Works
The process starts off by recording a .flac file with the hel...
I decided to write a pathfinding algorithm in order to expose myself to the world of pathfinding and for me to further understand more advanced algorithms such as A*. I chose C# due to its flexibility compared to other languages such as Java.
I will start with the basic objects and work up to th...
Thanks Santa!
I've been wanting to learn C++ more in depth for quite a while now, and this book should certainly help. :)
Without more of the code, it's not really going to be possible to address memory management or bottlenecks. So instead, I'll look instead at readability and portability.
Use the appropriate #includes
This program fragment requires two headers, which should be included but are not:
#include <s...
As we all know, hats are a very important part of this site.
In fact, the only reason I tolerate other people on the internet is so that once a year I can spend some time earning these glorious avatar noggin covers.

I don't understand how 'if not x % 2' would return True. Wouldn't that be the opposite? From that part of the code I read that if x is not divisible by 2, then return True. What the heck?
def is_even(x):
if not x % 2:
return True
else:
return False
I have a medium sized ASP.NET MVC application that should be improved in terms of responsiveness. Some jQuery is used to do some operations asynchronously, but I want to use AngulaJS as much is possible.
Since am new to angular and the time is short, I thought of leaving MVC views (no single pa...
This morning I've seen this on Twitter:

I was trying to achieve a simple problem :
If the user is an employee of the store, he gets a 30% discount
If the user is an affiliate of the store, he gets a 10% discount
I came up with the following :

abstract class Customer {

While fiddling around, I've made a very simple and naive function to retrieve any repeated sub-string within a certain string.
function getRepetitions(str, length){
if(isNaN(length))
{
throw new TypeError('length must be a number');
}
if(length < 1 || length > 2147483647...
I have been working on a software since a while in Java, and started the designing phase of it. I use JavaFX for the GUI, and use FXML for defining Scenes. I want to get the code reviewed which is related to how I handle the user interface. Like, how I render different pages, etc. Would that be c...

On Wikipedia, if you click the first non-italicised internal link in the main text of an article that's not within parentheses, and then repeat the process, you usually end up on the "Philosophy" article (see this Wikipedia essay).
To test this idea, I made a simple Python module that does the ...

Aside from Malachi's remarks about capitalization of keywords and indentation of the code, I would add two points about variable naming:
DON'T use variable names that start with @@, as they are reserved for T-SQL functions. This would now give a conflict between the parameter @DiscludeTables an...
