I've been chewing on this for a while now. I can't really convince myself one way or the other whether the blocking wait method is better or worse than blocks.
So, my thought is this.. in addition to waitOnAllNodeMovement, which in the end, seems fine, why not provide at least one non-blocking ...

I'm looking for some feedback on my lock-free queue, based on Disruptor.
Mainly I'm looking for any potential concurrency issues - such as where I need additional fences. It looks correct to me, and I can't seem to able to break it, but I'm only testing it on my x86 machine..
Other criticism is...
To test the queue I perfected from one of my CR questions, I've developed a maze program that receives an input maze, starting and end positions, and solves it. I have separate software that handles the maze execution and file parsing. I'm curious as to whether my implementation is optimal (fully...
I've been learning F# for a month or so and I'm wondering how good my "functional" aspect of coding is. When I first started, I did this using an iterative approach with a lot of <- and mutables etc. I tried to rewrite it as functional as possible. Any critique is appreciated.

Is this considered good coding practice?
I am getting the unique_id from get_unique_id_for_username but if that function returns false, I use that in the if statement to move on to something else.
// Check against usernames.

I'm trying to solve PRIME1 in SPOJ with following scala snippet.
object _002_PRIME1 extends App {

It all works except for the iterator part.
I just need it to where the code can only print the words from the text file once.
For example if the text file had the sentence : "A dog ran next to a very big dog".
The output of the program should be :"A dog ran next to very big" .

I wrote this together for a test I'm doing. What I'm mainly interested is if this code follow common best practices and if there are any improvements I can make in terms of memory efficiency.

I have this command line program for computing GPA (grade point average). Given credit sequence \$\langle c_1, c_2, \dots, c_n \rangle\$ and grade sequence \$\langle g_1, g_2, \dots, g_n \rangle\$ (I assume European grades, i.e., \$g_i \in \{ 1, 2, 3, 4, 5 \}\$ for all \$i \in {1, 2, \dots, n}\$)...

I'm playing with Haskell's list comprehensions, tuples, and foldr.
The exercise I've given myself is to find all triangles with a perimeter of length 26 in the set of triangles whose edges range from 1 to 10 in length.
main = do
print triangles
triangles = [(a,b,c) | a <- [1..10], b <- [1..1...
When iterating over the members of an object for logging the keys / values one gets a "stair case" effect.
Therefore I wrote myself this function which takes care for a left-alignment of the values.
Any hints concerning flaws and improvement-recommendations welcome.

I want to see how much fuel it takes to send a rocket into space. By changing the initial fuel, after I pass 1250 tones, the speed vy becomes negative. Even by keeping the fuel under 1250 tones the rocket doesn't manage to fly so far. Is my implementation correct?

Question: I have to display the given triangle is: Equilateral or isosceles or None of these.
I did everything correct, but the system said test case failed. Can someone say what test this code would be failing?
