I have decided to create a simple Option type for C#. I have essentially based it on the
Scala's Option.
It was mostly a fun exercise, but it might come in handy at work or any other project, even though it's less powerful than the Scala version.
Now I'd appreciate all remarks regarding this little piece of code, but e... |
Is there a better way of creating this terminal animation without having a series of conditional statements (i.e. if ... elif ... elif...)?

num += 1
return '[= ]'
elif num == 1:

I'm trying to optimise my implementation of a static kd tree to perform orthogonal range searches in C++.
My problem: The code performs slowly even for a small number of queries when the number of points is around 105.
I've constructed the tree based on this (i.e, It's a static kd tree where the data is stored both in ... |

I'd like to find a way to do what this method does in a cleaner, less hacky looking way
def self.create_from_person!(person)
spi = new(:person => person, :provider => person.provider)
spi.age_eligible_code = participant.age_eligible?(person) ? 1 : 2

I'm working on a javascript intensive user-interface application. (At least it's intensive for me, it's my first serious javascript project).
I have a few jquery functions going whenever a div is rolled over or mouseout. For example there are some divs which are draggable objects, and so when they are mouseovered, the ... |
I'm currently changing some legacy code over to PDO. The below code works, but not 100%. I would like to know if it's best practice or if anything can be done better.

'host' => 'localhost',
'username' => 'root',
'password' => 'root',
'dbname' => 'local');
