So I run this site: http://sometimesredsometimesblue.com
And more or less out of curiosity I was wondering if there was a more concise/elegant/interesting manner of how to code the... "functionality".
var redOrBlue=new Array("#0000FF", "#FF0000")
document.bgColor=redOrBlue[Math.floor(Math.random()*redOrBlue.length)]
There's nothing ...

This is probably a super easy question, but I just wanted to make 10000% sure before I did it.
Basically Im doing a formula for a program, it takes some certain values and does things when them.....etc..
Anyways Lets say I have some values called:
N

True_Retrieved.
I also have a % "scalar" ill call it, for ...

How is exactly that we talk about "true random" numbers when we are actually measuring something. I mean, isn't measuring almost the opposite of randomness.
Som articles says that, for example, throwing a dice is "true random". Of course it isn't Pseudo-random, but is it even random?? If you could have a machine that throw dices from de...

There are plenty of SO questions on weighted random, but all of them rely on the the bias going to the highest number. I want to bias towards the lowest.
My algorithm at the moment, is the randomly weighted with a bias towards the higher values.
double weights[2] = {1,2};
double sum = 0;
for (int i=0;i<2;i++) {
sum += weights[i];
}

I am trying to select existing images from a directory. The image files are being renamed dynamically when they are created but the format they currently have cannot be changed. This is an example.

Essentially, the images are names according to upload time and incremented. Perhaps split the file name into ...
In a web application if a user check the Remember Me box I'm gonna create a cookie and save it in database and assign it to user (long-life cookie). On any page request (page_load) I check this cookie (if session is null) and ask DAL for user object.
If I use GUID it would be unique but the question is if a user can guess the pattern may...
I have a function, which creates some random numerical results. I know, that the result will be an integer in a (small, a - b approx 50) range a, b. I want to create a function which execute the above function let's say 1000000 times and calculates, how often the each result appears. (The function takes a random generator to produce the ...
i want a little php function to choose a number between 0 to 5, with 50% percent chance that it will be zero, and also choose between two strings at the same time randomly:
the algorithm:
choose number between 0,1,2,3,4,5 randomly
(50% chance for zero, 50% chance for 1,2,3,4,5)
and
choose string blue, yellow randomly

For this Wordpress site, I need to generate 24 variables each of which contains a number between 1 and 24. The problem is that two variables cannot have the same value. So I basically need to generate 24 variables each of which contains a number between 1 and 24.
Here's the code that I am using to generate a random number.

Okay, final question and I'll have finished my number guessing game in Common Lisp! :D Whenever the game starts (or a new game begins after the first game), the following function is called.

In this case, the MAX is only 5, so I could check the duplicates one by one, but how could I do this in a simpler way? For example, what if the MAX has a value of 20?
Thanks.
int MAX = 5;
for (i = 1 , i <= MAX; i++)
{
drawNum[1] = (int)(Math.random()*MAX)+1;
while (drawNum[2] == drawNum[1])

Hi,
Sorry for the long question. I decided to explain the context of the problem first as maybe there are other solutions to my problem. If you're in a hurry, just read THE QUESTION below.
(EDITED -- In the mean time I added some attempts to solve the problem. The fourth one has my final conclusion, you can jump straight to it.)
