I have two Kafka consumer ConsumerA and ConsumerB. I want to run these two kafka consumers independent of each other on the same machine. There is no relation between them at all. These two kafka consumer will work on different topics on the same machine.
Each consumer should have a different P...
I'm learning LISP and am starting with Project Euler. I would love some initial feedback on my LISP code for this simple task.
I know it spits out the correct answer, but what I'm not sure about is if I'm using LISP the way it is intended (and the way to strive for in the future in order to achi...
I have two large 2-d matrices that are already known(dimension 2000x2000). The following code is a loop that forms a critical section of the code and consumes a large amount of time(over 70%). Is there a way to make it faster? Can multi threading help?
#a and b are the two matrices I already hav...
I'm looking to use LISP as best I can, not just get the right answer. This is very early on in my LISP career so feedback is welcome and exciting! Recently asked about Project Euler #1, got some feedback and incorporated into this answer for #2, but I know there's a LOT left to be learned!

I wrote this Console Paint program in C++. It's Windows-only.
I plan to add more features, but for now -- what do you think? What would you improve at it?

I am creating a small backend library that uses a persistent queue, where the queue is just lines in a text file. The purpose is simply to allow multiple processes to read from the text file, so that work can be coordinated across processes. In memory in each process, an array mirrors the lines i...
Sorry for the long title, but it feels fitting for the length of the code. I did try to segment and comment it best I could.

I am trying to compute a spherically symmetric function on a 2D grid. The simple solution that I came up with is the following:
Grid_side = 10
N_pix = 100
function = lambda r : 1.0 / r**2.0
grid_x = np.linspace(-Grid_side, Grid_side, N_pix)
grid_y = np.linspace(-Grid_side, Grid_side, N_pix)

I'm trying to get attribute value using oDoc
I feel there is a better way then this one i choose,
Do i have to catch the node and then to find the text Attribute or i can do it in one line ?
this is my code:

Dim str As String
Set node = .oDoc.SelectSingleNode("//animal/...

When coding I noticed I started to get into a habit of not using if-else statements when the else block only has one line of code. For example, if I have code that can be solved like this:
public Person(int initialAge) {
if(initialAge < 0){
System.out.println("Age is not valid, setti...

C is naturally clumsy at polymorphism but I wanted to avoid duplication so I wrote this function. But I'm sure there are ways left to improve it. Please not that for brevity's sake not all data types have been included.

I have a habit of shortening if-else statements from
if(bool){
int = 1
} else {
int = 2
}
to
int = 2
if(bool){
int = 1
}
Do either of these run faster than the other? I prefer the second example because it's shorter, but is it a bad habit?

I have a piece of code that looks like this:
