I'm trying to come up with an alternative to the gmean implementation in scipy, because it is awkwardly slow. To that end I've been looking into alternate calculation methods and implementing them in numpy. My only issue is that a method that in the two methods I'm implementing, the one that I fe...
I have a local database in Windows Phone 8 app. The app includes a lot of queries to the database and I don't want bad effect on the responsiveness of UI.
For example I have a table of users and method to get a user from database by id.

I am a beginner to coding and I need to write a function.m file. I am having trouble defining the function
$f(theta) = ((r^2)/2)*((2*pi*p)-(theta - sin(theta)*p))$
where radius $r = 30cm$ and density $p = 0.82 grams per cm^3$
So far, I have written:
function y = function(theta)
r = 0...
Having so many loops running concurrently obviously can't be good, and the code seems overly complicated. There has to be a simpler, more efficient way to

I am writing a method to synchronize the local Core Data entities with a remote web service (in this case Parse.com).
To update changed or created objects, I fetch all where the "updatedAt" date property is larger than the last local sync date. So far, so good.
But I am struggling with the dele...
What’s the best way to format a number?
If decimal is less than 2 digits, add zero to make it 2 decimals, if more than 4, truncate to 4 decimals, if 3 decimals, keep it to 3 decimals
14 => 14.00
14.1 => 14.10
14.123 => 14.123
14.12347 => 14.1234
I don't want rounding to happen

Robert C. Martin in his Clean code states that functions should do only one thing and one should not mix different levels of abstraction. So I started wondering whether the code below meets these requirements (I assume the answer is negative). Which one is better?

Some days passed and I feel like I should share the changes I have made so far.
Naming
I started using page names instead of color names on classes and variables. This leaves me with the benefit of being able to change the color scheme of an entire page only by changing the value of the color v...
I recommend splitting your function into a DOM-and-event-handling function and a text-analysis function.
function alignTextColumns( text, delimiter )
{
…
}
button.addEventListener( 'click' , function( event )
{
output.value = alignTextColumns( editor.value, token.value );

Your first F# code isn't too bad. I've made some small simplifications to streamline your code a bit and take advantage of some built-in F# functions:

let mutable reader : StreamReader = n...

How active is your chatroom?

It was asked: Anyone know how to formulate the voting data as a pivot:
Here is a first stab at the critical voting factors for CodeReview since 1 Jan 2013.
This does a pivot-table on the voting data, and plots the results as a graph over time.
Here is my full code (updated as of question post time). It is working fine but the performance time is approximately 5 minutes and 29 seconds. I am dealing with 1090 images.
This algorithm is supposed to organize and visually duplicated images. So what I do is compare 2 images at a time; 1 the ...
What you did well on:
Your program is easy to read.
You are allocating memory, even though it is unsafe in certain cases (other answers have addressed this, so I won't cover it).
You prepare for some corner cases.
Things you could improve:
You are returning 0 when your program runs into a...
