I have a method that generates a 10 digit random number where each digit occurs only once.
eg:
0123456789
3645720918
Is there any way this method could be optimized/improved?
private static String randomize(){
Random r = new Random();
List<Integer> digits= new ArrayList<...
I created this out of curiosity and it has some code duplication issues and the fact that sticking .yeild() on the end of a call to a unit converter is pretty strange.
How would you improve it?

Here's my spec_helper.rb
Having been through hundreds of often-conflicting posts on testing with RSpec, Capybara, FactoryGirl, Spork, Guard and Devise without Cucumber, this is the spec_helper which "seems to" work.
I'm bracing for it to blow up or not work like the previous attempts.
Questions...
I've got the following query builder. Some of the cases have the same piece of code (those that have a parameter).
I know it's not good to duplicate code that much if at all.
How would you suggest I improve this loop?
for ($i = 0; $i < $len; ++$i) {
switch ($conditions[$i]['condition']) {

I've got the imperative styled solution working perfectly.
What I'm wondering is how to make a recursive branch and bound.
This is my code below, Evaluate function returns the optimistic estimate, the largest possible value for the set of items which fit into the knapsack(linear relaxation).
Fo...
(removeAll a L) returns the list L without any occurrences of atom a.
I can only use car, cdr, length, null?, and SUPER basic stuff like that to make the recursion. Anyone know how to do it? :)
Introduction
MongoDB does not provide means to lock a document (like SELECT FOR UPDATE in RDBMS).
There is recommended approach to Isolate Sequence of Operations, which is sometimes called optimistic locking, but there are scenarios when this approach seems to be overly complicated or even inef...
I want to optimize this function in R (optim function) to obtain MLE of Teta (vector of 5 unknown parameters) But I guess i need some help
Thank you.
I need to know how it works de len() built.in function on Python. Thanks so much to all answers.
I create series of objects out of Student Class and store them in a vector. I write each object in to a .ser file once it created. Then I read them back. My code is working perfectly. What I want to know is, I do this in a correct optimized way or are there any easy and optimized ways to get this...
I have written the script, which unzips a zip file (passed as argument to the bash), loops through directory and files, then perform different actions based on directory or file. It is working fine.
However I would like to know some things:
Is it possible to do this without the unzip command? ...
How to make this idea work?
let rec apply f args =
match args with
| x::xs -> apply (f x) xs
| [] -> f()
Is there any way to write a function to get another function of any signature as parameter (like Delegate type in C#)?
Is there a simpler and optimized way to calculate listAdminCorePriveleges and privileges ?
public string[] GetPrivilegesForUserByPersonEntityId(int personEntityId)
{
var listPrivileges = new List<string>();
var listAdminCorePriveleges = (_accountRepository.AsQueryable()
...
That one is quite simple (for me at least) since there is a very general answer :)
NO
There is no way you can ever really safely "repair" user input.
"Please provide a list of everything you shouldn't to with a hammer"
is way harder than
"list all appropriate uses of a hammer".

I recently gutted and redid my game code to be object oriented (before it was just functions and a mass of global variables.
Before I go an make more functionality happen, I would like to take one last step backwards to make sure I have the best foundation I can before proceeding.

I wrote some very basic R code.
This has at least two problems.
1 - It uses a very basic imperative-programming style instead of good R style.
2 - It draws the result as an ellipse, not a circle. This effect is barely visible on RGui on Windows, but extremely visible in RStudio on Linux. [Edi...
this code looks very clean,
it looks like it handles edge cases well.
I especially like the way that if it converts to the specified data type that it does it and doesn't make you convert explicitly. that is very slick!
I would definitely like to see some code that puts it into play.
not mu...
Here is my solution:

scope.test = @test()

#-----------...What currently occurs when I run my game is that the frustum seems to be there in some capacity but just offcenter or not moving with the camera. I think it may have to do with my matrices or the way that I set up my frustum, due to the fact that I read a tutorial and cannot remember if OpenGL is...
