concat() multiple columns but some fields are NULL, does it just skip them? 
Below is a function which iterates through a multi dimensional array of regions, adding them to a hierarchical taxonomy in wordpress.
Im trying to understand how this function works (I didn't write it), specifically how the $global is being used to store the parent of the iteration, and how tha...
I know this PHP solution worked in the past: (change username and password) This only works if the mysql server is the same as the webserver.

The h:commandButton attribute action requires you to return a String

The action attribute accepts a method-binding expression for a backing bean action method to invoke when this component is activated by the user. An action method must be a public method...
The short answer is yes, yes there is a way to get around mysql_real_escape_string().
For Very OBSCURE EDGE CASES!!!
The long answer isn't so easy. It's based off an attack demonstrated here.
The Attack
So, let's start off by showing the attack...

I was reading about similar problems to the one I am having, and my guess is that I am having a 'memory leak'. I'm not sure exactly what that means, or how to correct it. Could you take a look at my code and help me optimize? LastRow in this bit is a little over 70000.

May I add that you could try using alias to alleviate the situation a bit. However, you will have to add the using alias on top of every source file :

if not, rename the one of t...
I built simple command line flashcard game for learning Korean. I'm beginner programmer, so just wanted to make sure I'm following best practices, especially pertaining to OOP principles.

Compilers can only inspect the method signatures, not the method body, so that part is irrelevant.
This "reduces" your code to (psuedocode):

I am relatively new to TDD and am trying to adopt better names for my tests.
I wrote the following tests abruptly and have since refactored them to the best of my ability, but despite my efforts, the test names are still (mostly) abysmal.
I am here today to ask that you review my test names.

I am learning nimrod and needed a few functions from libsndfile. Thankful for any comments/insights. I deviated slightly from libsndfile, to use namespace and stronger types that is available in nimrod.

Just formatting first
your code is missing indentation and has some extra Newlines in it.
Your Do Until loop should be double indented because it is inside of a sub.
You should also get rid of the extraneous commented code also. If you got it working, get rid of the junk.
Here is what the co...
This query currently takes approximately 250 seconds to run and I'd like to reduce it by as much as I can. I have tried using left joins instead of subqueries and it increases run time.
Thank you!

I am using C# to get the users input of how many buttons to change the color of. The buttons are in rows that have 1-10 button in each. If the user enters 11 than the entire first row will be filled out and the first button on the second row will change color. I have figured out how to accommo...
I've written an interpreter for a simple assembly like language and it's performing slower than I would like.
It's split in 3 files. The Parser that converts the source to a vector of ints, the VM that actually runs the bytecode, and Tests that has a bubble sort written in the language.

Yes you can move the output away from the code, however that's usually difficult to do with this type of procedural code. The code is extremely tightly bound, which makes separation harder than it should be!
The two function you call are fine as they are. So lets focus on those for now.

I like how you've written this code. Just a couple of nitpicks:
Consistency with var
var remainingTasks = tasks.ToList();
int count = remainingTasks.Count();
var exceptions = new List<Exception>();
Why not use var to declare count? Seems pretty obvious to me that remainingTasks....0
Most of the really good feedback is already given, but I have one last recommendation:
If you're going to use audio clips instead of using MIDI, why not use a simple library like tinysound?
It takes care of so much, and is available under a BSD-2 clause license.

Use Case
Fairly new to Lodash/Underscore. The use case is to convert an array of objects into a hash map where one property is the key and the other property is the value. Common case of using this is converting a "link" object in a hypermedia response into a hash map of links.
