In the future there is a good chance that I will need to support another database like mySQL. How to make this code open to extension, but closed to modification?
foreach (ConnectionStringSettings connectionStringSetting in
configuration.ConnectionStrings.ConnectionStrings)

Connectio...
This is what I've been doing so far in my business layer to return error messages to the user.
public void CreateMerchant(MerchantCreationModel model, out MerchantCreationStatus status)
{
//check if merchantId exists
MerchantDTO merchant = _merchantRepo.GetMerchant(model.MerchantId);

Building on @RubberDuck's recommendations, I now have something I find... beautiful. I'm sure there's a couple of things left to polish - this site is about making great code out of good any code, right?
This code requires trusted programmatic access to Visual Basic Project.

I'm currently playing with the Typeahead problem on Talentbuddy. There are already 2 questions on this subject(Typeahead Talent Buddy and Typeahead autocomplete functionality challenge), but none of these use a trie which is why I created a new one.
Problem Statement
Given a big list of user...
In addition to what @200_success said, I would like to mention one thing:
Old-style join
This is an old-style join:
select id2
from friend f, highschooler a
where a.name='Cassandra'
and a.id=f.id1
While they work just fine, they are ANSI-89 and they are not the norm and it would be good for ...
I have to write a unit test for the method processRequest in the servlet below and I'm wondering if:
It just shouldn't be done.
The class should be rewritten / refactored to allow easier unit testing. Suggestions as to how?
There is a meaningful way of getting the value of response.getWriter()....
Status codes have long gone the way of the Dodo --- made extinct by exceptions, actually.
The problem with a status code is that it can be ignored. An exception cannot. Consider these two examples.
Using Status Codes
First, the "merchant repository" implementing CRUD operations for merchants:

I'm using Dashing http://shopify.github.io/dashing/ to create a Google Calender widget provided by https://gist.github.com/akalyaev/6387762 to parse .ics files from my Calendar. I have followed the instructions to the T and have installed the gems as necessary and when the event is sent I get an ...
I want to write a search that raises an error if the list supplied is not sorted. This seems like an O(n2) problem in itself, which defeats the purpose of the binary search. Also looking for other comments on the search itself, alternatives in ruby.

Assume that we have a function that takes array and exchange all elements with their power with exponent 2:
void pow(int* arr, int count)
{
for (int i = 0; i < count; ++i) {
arr[i] *= arr[i];
}
}
How can I speed up this code? I mean, the part with multiplication.
I was thinkin...
This is a follow-up to Array-like container for uints shorter than 8 bits
In short: The PackedBitfieldArray should be a kind of container for packed (unsigned) ints shorter than 8 bits. It provides proxy objects for manipulation and iterators.
What I have changed:
PackedBitfieldArray::end() n...
For heap (array based) sort, we need to start at index 1, ignoring the 0th index. If I want to make a static function like
public static void heapSort(int[] array){ }
The user shouldn't care about leaving the 0th index empty. And I don't want to allocate a new array (only to start from the 1s...
I quickly wrote a Brainfuck interpreter in javascript last night, it worked great and i was very proud of how quickly i created it and it worked , then i encountered the problem of nested loops,so i quickly started working on updating the code, but with no success , i have spent 5/6 th of my enti...
Look what I found
Dim procedureName As String, lastFound As String
Dim procedureBody As String
Personally I don't like declaring variables like this, and almost every language allows you to do this in some way or another.
I think this is one of those holy war issues though, some programmers ...
On Stack Overflow and our other code-related sites, creating a minimal, complete, and verifiable example is the best way to get an answer to your question. We’ve always loved JSFiddle and sites like it because they let both askers and answerers reference runnable, working code that demonstrates their problem or solution.
Unfortunately, the use of these external sites introduces a few problems:
If the link breaks, the post becomes worthless.
If the code isn’t embedded in the page, visitors are forced to go elsewhere to get the full content of the question or answer. …
