I'd already asked for my code to be reviewed earlier here: question

Considering the suggestions put forth for that question, I spent a day and refactored my whole code. For those who have seen my previous question/code could you you point out anything which I have as...
I've been trying to understand the original MVC implementation (the Xerox Parc's one: http://heim.ifi.uio.no/~trygver/2003/javazone-jaoo/MVC_pattern.pdf). I'm sure it has flaws, but it's a simple code to practice/learn the original MVC.
Working example: http://jsfiddle.net/2D4ST/

You can get rid of the <type_traits> header but replacing your std::enable_if by a bool template specialization:
template <::std::size_t, ::std::size_t, bool>
struct expand_indices_impl;
template <::std::size_t A, ::std::size_t B>
struct expand_indices:
expand_indices_impl<A, B, A==B>
{};

Since you try to mimic the style of STL containers (at least, that's what your comments say), there are several things you could improve:
STL containers subtypes
Most of the STL containers have subtypes. I am pretty sure that some parts of the library uses these subtypes. So, if you want your c...
Let's improve the function step by step, focusin on readability as well as on the algorithm itself.
I believe the type of the function is not what it should be. We get a list of characters, and we should produce a list of lists:
pack1 :: [Char] -> [[Char]]
pack1 xs = foldl (\acc x -> if not(nu...
I am making a small side scrolling android game for fun. I am having a problem with my collision detection. I can't seem to find the problem with this code. Can you look it over and try and help me! thank you!

I was just writing code, and wanted to make a piece that removes everything after the character "?" if its found within the url.
My code:
if (strstr($url, "?")) {
$url = strstr($url, "?", true);
}
Can I make this any shorter? It doesnt feel right to type the "same thing" twice with strstr.
I already read Design pattern for implementing multiple data sources. I was hoping for general advice.
I'm writing a service which will go to numerous datasources, each source requires getting copious amounts of data and changing it to a single format. I'd know what the best pattern is for s...
I have the following code for the rock, paper, scissor game. The code works fine in python 2.7. Are there other more concise, more readable, or more pythonic ways of solving this problem in python?
player1 = raw_input ("?")
player2 = raw_input ("?")
if (player1 == 'rock' and player2 == 'scisso...
As a counterpoint, here are a list of highly ranked, small-code questions that have high quality answers, and are generally successful:
Each element is the sum of itself with the next element of a List: now do this point-free in Haskell

I think these questions invite low-quality, short, code-only answers and decrease the overall quality of questions on the site.
They are too narrowed down on a specific issue and leave very few possible answers, and can be answered with a mere comment.
I think the ought to be closed, ideally wi...
I know this is rather trivial, but it gets at me every time.
The following code snippets are functionally the same, but I'm wondering which is cleaner.

}
Or

Of course, retur...
I've two working ways to do so, but which one should I use?

" Characters: " + text.replace(/\s/g, "").length +

In C, using sleep() would make the program wait for a short interval of time:
sleep(2000); //or whatever the number (in milliseconds)
But I really don't want to include unistd.h just to use sleep, so I'm doing it this way:
for(int i=0; i<=100000000000; i++); // <----- note that the loop doesn...
I would like to know some tips between LinkedHashMap and HashMap.
what are the similarities between them ?
what are the differences between them ?
if I don't want to use sorting , is HashMap more preferable to choose ?
when I focus on performance , what will you suggest to use ?
How these two ...

A few random notes:
FileNotFoundException is a subclass of IOException. Declaring both FileNotFoundException and IOException is redundant.
The Sampler() constructor can be omitted, since it is just the default constructor that would have been implicitly defined anyway.

Well then, here's my first question on this site. I was assigned the task of copying some subsums from a given EXCEL-Sheet into the executing EXCEL-Sheet.
This had to be done with an EXCEL-Macro, so non-programmers can easily use it. There was the need to compare the final sum of copied values ...
I wrote this simple HTML parser in Ruby.
Basically I have a folder that has files. Every file has crawled web pages. The only addition within these files is before the HTML content there is a page metadata, #URL is one of them.
What I am aiming is to have two files:
