After watching Raymond Hettinger, I decided to go through my code and make it faster and more beautiful. The example given on the slides is, unfortunately, not good enough to get me going (ref. https://speakerdeck.com/pyconslides/transforming-code-into-beautiful-idiomatic-python-by-raymond-hettinger)

I've just implemented a cache for my server, and I'd like your thoughts about performance improvements and maybe some possible bug fixes:
public class Cache<CacheKey, CacheValue>
{
private Dictionary<CacheKey, KeyValuePair<CacheValue, DateTime>> _map;
/// <summary>
/// The first element is the least recent... |
I've recently written a program for Python 3 that I'm using to practice my newly-acquired object-oriented knowledge. It's a simple text game that is really easy to play and can be run straight out of IDLE with no modules (except the Random module). I realize that beginner code can sometimes be sloppy and difficult to r... |
I was wondering about the best way to return the most common items in a list. So far the best way I could do it was:
//@param string $this->matched_ids_list = 1,11,12,11,12,
$this->matched_ids_list = "," . $this->matched_ids_list;
$this->ids_count = explode(",", $this->matched_ids_list);
$this->ids_count = array_uniqu... |
I'm open to any advice to help improve this code for general use.

I'm trying to merge counts for items (URLs) in the list:
[['foo',1], ['bar',3],['foo',4]]
I came up with a function, but it's slow when I run it with 50k entries. I'd appreciate if somebody could please review and suggest improvements.

I'm (very) new to Scala, and decided I'd try to get a handle on some of the syntax and general language constructs. This currently doesn't implement any backtracking and will only solve things if they can be derived exactly from the values given in the initial board.
That being said, I don't particularly care about a... |
The following piece of code executes 20 million times each time the program is called, so I need a way to make this code as optimized as possible.
int WilcoxinRST::work(GeneSet originalGeneSet, vector<string> randomGenes) {
vector<string> geneIDs;
vector<bool> isOriginal;
vector<int> rank;
vector<double> value;
vector<... |
