In my question to learn F#, I've decided to get one step closer to creating a programming language, and implement this simple Reverse Polish Notation "interpreter" of sorts.
It does not allow for parentheses in input ( ), and only accepts expressions containing the following valid tokens:

This is a problem in CodeEval, moderate level. The problem is very easy for this level. But I am not able to get more than 60 points for any solution I submit. (Moderate levels highest score is 65 and they take speed and memory into consideration)

I'm working with a database that has typos in the values. To compensate for them I've made a function called standerdizer() which removes spaces and converts all letters to uppercase. I do this so the value red in from the database can correctly be interpreted by the program. Also in values start...

I have a two-phase fading button. I have noticed that the order of opacity states are declared is important.

I have created this code for both boolean and integer values to display a truth table for an "AND","OR","XOR", "NOT" gate. However I think that my code needs reviewing as it could be simplified.
public class LogicalOpTable {

boolean p,q;

I wrote the following program
int main()
{
int a;
scanf("%d", a);
return 0;
}
It gets segmentation fault at the time of execution. It is correct because of fault memory.
Then I wrote the following program
int main()
{
char a;
scanf("%c", a);
return 0;
}

I'm looking for tips on:
Efficiency: While the find-and-replace approach I have works perfectly fine and does so in a relatively quick manner, it feels far slower than it could be.
Idiomaticness: As always, I like writing...

I wrote a program to solve a magic numbers puzzle. The puzzle works like this:
You have an NxN square where each row, column, and diagonals add up to x except some of the numbers in the square are switched. Find the numbers that are out of place and switch them.
Here's an example:

This is a followup of the following question: PHP function to create a Hex dump

I'm curious as to why this question got migrated to Stack Overflow, mostly so I can ask in the correct place in the future. It's about unit testing a functioning python module, the unit tests all succeed and are viable tests of the functionality but were not (still are not) elegant. Why is Code...
