I have written an isRotation function that calls on isSubstring only once(I am allowed to call it only once). I have implemented my own version of isSubstring as well. Any advice is much welcome!

I need to get the distinct sums of naturals of a natural
What I came up with is
type Sum = Stream[Int]
def makesums(i: Int): Stream[Sum] = {
def schmear(sum: Sum): Option[Sum] = sum match {
case head #:: s #:: tail if (head - 1 >= s + 1) => Some((head - 1) #:: (s + 1) #:: tail)

How can I improve my code and make it more idiomatic?
package pascal
func NextRow(prevRow []int) []int {
x := make([]int, len(prevRow)+1, len(prevRow)+1)
x[0], x[len(prevRow)] = 1, 1
for i := 0; i < len(prevRow)-1; i++ {
x[i+1] = prevRow[i] + prevRow[i+1]
}
return x

For my current project I need a basic UDP server. The first priority is to make it as fast, but as resource friendly as possible (it will be run on Raspberry Pi-like devices).
I would like a review about the general code 'quality' and logic. I know that I am missing some error-handling at the mo...

Disclaimer: I'm a simulations programmer, so this is kinda-sorta my bread and butter. Sometimes people even call me a wizard when I solve problems.
There's a few major pieces you can focus on. Draco18s mentioned unit testing, which would be a very natural process for weeding out bugs. Take ea...
My primary concern is that this has been written as a global function. I think it would be better if this was a function of the SignalProducer class but I am not sure that is even possible. Is this thinking justified or is the use of global functions acceptable?

I completed writing a dice roll script in Python but I thought it looked too messy. Is there anything I should change here?

result = []
total = 0
def __roll_(sides=1):
return random.randint(1, sides)
def roll(sides=1, times=1):

I am brand new to coding in Python, and programming in general. I have picked up the Learning Python book and have been slowly making my way through it. I decided that I would try to implement what I have learned by writing a simple word-based game that I could run through the Mac OS Terminal.

It seems odd that state must be passed around all the time. cant State module hold it self, so i could do something like
state = %State{size: size}

Here state is always passed. I suppose this is how it is in fp?

The problem is to divide a list into n parts according to a predicate. I found recursive solution but I am sure that a more elegant solution also exists.

This is a section of code in a program I have created to store and review the results of a game based upon the "class_number" the user gives. This section is very bulky and I was wondering how I could make it more efficient.

if class_number == 1:

I am currently working on a project in Java, and I use JavaFX for the GUI of the System. Currently, I am in the designing phase of the system, where I am designing the look of the system as well as setting up the basic functionality like navigation.

I need to add a field with a default value to all documents which don't have this specific field.

I added a question in stackoverflow but it is closed due to it doesn't belong over there so please review it here
It's not clear why you would need to p/invoke the native MessageBoxU function, given you're not using it anywhere, correctly preferring the language's own MsgBox wrapper.
Remove all the dead/commented-out code if you're not using it - otherwise is obscures the intent of the code.
As far as I kn...

A friend of mine wanted an array-to-CSV string function for Node.js, so I came up with this. Basically, it can take in a single object, a 2D array or an array of objects.
If the children or parent is an object then the object properties become the headers, if the children are arrays then the fi...
I have two similar libraries for use in an embedded system (Teensy, sort of like Arduino). One is for debouncing a digital pin, the other is for reading a capacitive pin as if it is a debounced digital pin.
They have similar APIs:

I came across this problem by accident and gave it a go. I think my solution works as it has passed all the unit tests I wrote. Given I just started learning F# a couple of weeks I would love to have some feedback on the code regarding both its accuracy and its quality.

I wrote some code to implement a way to filter the arguments of a variadic template based on their type.
My current solution requires many helper meta-functions and I'm sure that there must be a better way. How would you improve this?
