I wrote this quick script to convert a genotype file into a BED file. Running it seems to be taking a very long time.

#2.ch...I've been working through the problems on Coderbyte and this on has me stuck. The assignment is to built a piece of code that processes a string and returns True if all lowercase alphabetical characters are surrounded by plus "+" signs (e.g. +d++e+==+d+) and returns False if even one is not (e.g....
I am not sure what I am missing. I am pretty new to C++, and GLSL, so I am not sure if I am screwing something up with the C++ in general, or if I am failing to handle the OpenGL context correctly?
The main function (code for handling window creation is missing. If you think you may need to, jus...

I've contacted SE yesterday to burninate a few tags. Something apparently went wrong, causing these tags to "recreate themselves" and appear as new, with a few questions left over. One of these questions only had these tags (automatically giving it untagged), and I've fixed that by giving it a ...
The biggest problem with using a for-loop to do this is that you are wasting CPU power.
When using sleep, the CPU can, in a sense, take a break (hence the name "sleep") from executing your program. This means that the CPU will be able to run other programs that have meaningful work to do while y...
In December 2013 we held a bunch of weekly weekend-challenge events, which was fun, and generated posts that made it to the site's newsletter, week after week. One may want to tweak this query so as to filter posts created before December 30th, 2013.
Some weekend-challenge stats up to that date:...
I'm builing a bin tree. Exmple: key AAAA1.ETR, value 1.
I'm reading files with this structure:

Data can be compressed or uncompressed(this is saved in flag). Data contain mor...
I have an array of integers and a number n. I want to sum the elements of the array and return the index where the sum passes n, as efficiently as possible.
For example, assume:
theString = "6-7-7-10-7-6"
theNumber = 33
expected result: 5
This does the trick but not very efficiently: (and e...
I was working with this problem and here is my code.
Basically the problem is to find the number fo zeros at the end of any factorial.

cout<<numeric_limits<int>::max()-1000000000<<endl;...
Program must to find duplicate files (by content) in a given directory(and subdirectories).
I collect all data in Map<Long, ArrayList<String>> map where Key is the size of file and Value is the List of paths to files with the same size.

I have written an implementation of the merge sort algorithm in Java.
Here is the MergeSort class that I created.

public static void sort(Comparable[] a){
Comparable[] b = new Comparable[a.length];
sort(a, b, 0, a.length-1);
}

I am very beginning in PHP and Design Patterns. I have been studying the beautiful book "Head first: Design pattern" and I have been working in some of the codes originally presented in Java in order to learn more about PHP-OOP.

Your improvedBinary.vbproj specifies:

I am trying to convert over to mysqli and wanted expert advice. Is the enclosed code 100% oop and also how secure is the code against attacks? I know nothing is 100% secure, but how good/safe is it? How and what can I make better? This is just a generic query as I wanted to get a basic model ...
