I need a list of Large Carmichael numbers( 10 to 100 digits ). Is there any website which provides such data. It would be more helpful if i can get a list of large odd composite numbers and primes as well.
Did you already try The On-Line Encyclopedia of Integer Sequences? Carmichael numbers are sequence A002997, and from there you can find a link to a Table of n, a(n) for n = 1..10000.
Here's the first 33: http://oeis.org/search?q=carmichael&language=english&go=Search.
This is generally a good site for sequences.

How can I test for the independence between two random variable given another one(i.e. whether P(A|C)=P(A|C,B) or not?) using available samples. in other words, I just have 1000 samplesf for 3 random variables generated by bntoolbox on Matlab and now I wanna test for CI between arbitrary random variables.
I've read something about Fisher's method but honestly don't understand it.
Thanks is advance.

This question does not appear to be about a specific programming problem, a software algorithm, or software tools primarily used by programmers. If you believe the question would be on-topic on another Stack Exchange site, you can leave a comment to explain where the question may be able to be answered.
Questions asking for code must demonstrate a minimal understanding of the problem being solved. Include attempted solutions, why they didn't work, and the expected results. See also: Stack Overflow question checklist

I've got a computer generated sha256 hash of which I need the original value.
I know the value is a random 64 character string of alphanumerical, lower and uppercase, numbers and underscores + dots.
Would it be possible in a reasonable amount of time to bruteforce this?
There are 64 possibilities in 64 positions giving a total or 64 to the power of 64 combinations which is 3.9402006196394479212279040100143613805079739270 × 10^115
So no. Even if you had every computer on earth working on it for 1,000,000 years you still wouldn't be close

I was doing this question of boolean algebra, Simplify f=Σ(8,12,13,14)+dΣ(3,7,9,10) using karnaugh map.. can anyone please tell me what is d in this question? I know its a stupid question but i couldn't find it on google. And please tell me what this question means? i mean like straight away simplifying without the d expression is okay but what does the d expression signify in here ?
d stands for 'don't care'. Cells 3,7,8,10 do not affect the value of F.
This helps because you might be able to get a simpler expression if you ignore those cells.

Has anybody experience of working on RulerBehavior of Visiblox charting toolkit? I am looking for some delta finding examples. Visiblox forum does not contain any such information. So if anyone can share his/her experience.
thanks in advance
Delta values?
As in Max value minus Min value?
Here is what I do:
double xMeasure = (double)MyRuler.MaxX - (double)MyRuler.MinX;
double yMeasure = (double)MyRuler.MaxY - (double)MyRuler.MinY;

I'm new on Matlab. I don't know how to load .txt file end then open it to start work. The file is composed by 1 column with over 10.000 elements. I'm going to open it and then to deleted some elements, these deleted elements must be more little than a fixed value, how can I do it.
Thank you very much for your time.
