“There are only two hard things in Computer Science: cache
invalidation and naming things.” -- Phil Karlton
That being said, I created this SimpleCache class which I intend to use to cache database queries and results over a relatively short period of time.
I'm just asking if there are a...
// X.size() == Y.size() > 0. returns correlation between X and Y
double Correlation(const vector<double>& X, const vector<double>& Y)
{
size_t N = X.size();
double EX(0), EY(0), EXY(0), EX2(0), EY2(0);
for (size_t i = 0; i < N; i++)
{
EX += X[i];
EY += Y[i];

Following up on List<T> implementation for VB6/VBA, I'd like some thoughts about the revisited IsTypeSafe function, below.
The previous version pretty much implemented VB.net's Option Strict setting, by only allowing widening numeric type conversions, and preventing implicit conversion between n...
Background
(TL;DR: This part can be skipped)
Today at work, I had to bring a component that used to load CSV data into MySQL, and perform calculations as result of SQL queries. I was tasked with replicating that in a programming language. The general example is like: There's a 2D array (a tabl...
My first COBOL program. I'd like to get a critique.
I am unfamiliar with best practices.
Particularly, I'd like to know about how to get the input and output to be more elegant and less dependent on how the file fields are structured.
Some type of analogy to C's scanf, getch, or any of the jav...
I have a select case that checks against a string variable. Its starting to get large and I am wondering if there is a better way of doing this?
Here is a smaple of the select case:
Select Case Param.ToLower
Case "dashboard_home_vm"
Return _Locat...
I am pretty sure that you can lose the CAST that surrounds the DATEADD function.
the DATEADD function should spit out a DATE datatype.
it should look like this:
SELECT EntryDate
,DATEADD(DAY, 1-DATEPART(WEEKDAY, EntryDate), EntryDate) AS 'SundayDate'
,DATEADD(DAY ,7-DATEPART(WEEKDAY, Entry...

I tried to do it using Haskell (learning Haskell).
Can you give me some good practices/shortcuts/advice on how to make this code better?

I would like to iterate through the records of a database table using a C# List of my custom class. Is this the most performant way to handle this? (Simplified for readability)
static void Main(string[] args)
{
int recordParentId = 1;
var records = GetRecords(recordParentId);
foreach (Rec...
