I have this rather ghastly if statement and I'm sure they're is a way to condense it but I don't really know how! Does anyone know how? I was told a case statement would work but Ive never used a case statement and I'm not sure! Sorry for any mistakes in this post! I'm a newbie to code review! My...

What is a Zombie? Why are Code Reviewers so violent and talking about killing Zombies all the time? And what ammo are they talking about? What is a TS? What does RSA mean?
And what other Code Review-specific memes are there?
(As the number of memes grows and grows, and Malachi's wish to vote fo...

I'm currently learning Java along with the Stanford online "Programming Methodology" course and, while it is awesome, I do lack any kind of human feedback.
So here is my question:
This exercise was to create a method that took a floating-point value x and an integer k and returned x to the powe...
Your function fails to calculate \$x^0\$ correctly. I would expect it to return Double.NaN when \$x = 0\$, and 1 otherwise.

My logic has to be written in this way, but I think the if expression is too long to read.
How can I make it more readable?

300THz transmitter? (the band between infra red and microwaves) - with a lot of technology and know how perhaps.
See http://www.rpi.edu/terahertz/about_us.html
300THz transistor/IC - no.
Use discrete inductors and capacitors at these frequencies? No. At very high frequencies conventional capac...
Here is how I would rewrite your code. I will add my comments after:
plotActivity <- function(
activity = 'codereview.stackexchange.com',
api_key = getOption('rescuetime_api_key'),
from_date = NULL,
to_date = NULL) {
## This function plots time spent on a given URL

I'm working with Python 2.7.5 and have written the following code:
def func(x):
if x == 1:
list = data.parseJSON(fileName)
person = [l for l in list if l['worker'] == sys.argv[1]]
displayPeople(flatten(person))
elif x == 2:
list = data.parseJSON(fileName)
person = [l for ...
I've implemented for the first time doctrine-orm on my soap server application, can you tell me if I could optimize some of the written orm related code?
More specifically, is it a good practice to package entities in sub-namespaces, or is it better to simple put them in an Entity namespace ?

How can I optimize the following code, with LINQ or some other trick?
var b = birds as List<Bird> ?? birds.ToList();
foreach (Bird bs in b)
{
for (int i = 0; i< bs.Nest.Count()-1; i++)
{
if (bs.Nest[i].X == bs.Nest[i+1].X && bs.Nest[i].Y == bs.Nest[i+1].Y)

Situation: I need distinct results from two tables, that both have duplicates.
I would like to know if I should combine UNION and DISTINCT.
Example 1 - Only use distinct
SELECT DistinctValue
FROM Table1
UNION
SELECT DistinctValue
FROM Table2
Example 2 - Combine distinct and union
SELECT DIST...0

I want to transpose this matrix input:
1.000 2.00 3.0 4.00
5.00 6.000 7.00000 8.0000000
9.0 10.0 11.0 12.00000
And get this output:
1.000 5.00 9.0
2.00 6.000 10.0
3.0 7.00000 11.0
4.00 8.0000000 12.00000
I have a matrix in a file with thousands of lines and millions of columns, so I can't r...
So I've seen so many different ways of doing this all seem very complex and all seem to be done in MySql. I'm using PDO in my project so I've had a go myself to see what I could come up with. Firstly is this safe? Secondly is there something I've missed a better way of doing it?
