I have tried to build my first MVC sign up form.
Here is the user controller method register:
public function register() {
if($this->isPost()) {
$user = new UserModel();
$result = $user->add($_POST);
if(!$result) {
$this->redirect('user/register');
} elseif(is_array($resu... |
I have a few hundred files in a directory that I need to read in parallel. Namely, the files that have the same name, but different file extensions (.a and .b), but they're pretty much plain text files. The corresponding .a and .b files have the same number of lines. I need to read each line into cell arrays x and y un... |
I have this function containing some loops and a double for loop. What it does is set up a matrix first to store results in (the task at hand is comparing genomes) and then with sliding window, calculate the differences between sequences. It's very slow for very long sequences, I was hoping somebody know how to speed t... |
This is a simple repeatable question regarding the usage of Python3's comprehensions:
Could the Python3 syntax be used in another way to speed up the process, further so the gap between Python3 and numpy would be reduced? (see chart below).
The results & code:

I have a method that parses XML into an array of hashes.
Here is the original XML:
<rowset name="skillqueue" key="queuePosition" columns="queuePosition,typeID,level,startSP,endSP,startTime,endTime">
<row queuePosition="0" typeID="20495" level="3" startSP="2829" endSP="16000" startTime="2013-03-04 16:25:50" endTime="2... |
I wrote the following function that takes a string and returns a new string with each word capitalized: first letter uppercase, following letters lower-cased.
It works, but I would be interested in seeing how a more sophisticated Haskell programmer would do this (if there is already a built-in, great, but still interes... |
I have an upload form on my site and I'm trying to sanitize and transform input data.
I will be straight forward to you - this is my first object-oriented style code! The reason I don't just want to use regular function, is that I would like to keep my codes divided in logical blocks. I called this one Filter. It has,... |
