I am writing a java program for my class but unfortunately I keep getting an out of bounds error when I run my code to this point. We are supposed to get for our professor a desired output--here I am trying to remove something from an array, but instead I always get the error.

I want to display images to the screen in their original colour, but this code is showing greyscale images. I want to use pygame.images.frombuffer() because it is the lowest resource usage. Also looking for formatting critiques and OOP critiques.

I'm trying to optimize the following lines after doing profiling I found them they are slow, I have no experience with optimization, I hope someone helps

The question Python: My program is unable to perform addition correctly which asked for an explanation as to why the code was buggy was closed as off-topic; I don't know about the last two close voters, but the first three used the close reason

I have seen this in a codebase:
Class MyComponent extends React.Component {
constructor(props) {
if(!props.value) return null
this.state = {
value: props.value
}
}
....
}
This is a React Component.
I am wondering what could happen if you return early in the c...
I've written a function to remove empty or "" value elements from an array or in other words return an array consisting only of elements containing a value.
Option Explicit
Public Function RemoveBlanksFromArray(ByVal TheArray As Variant) As Variant
Dim temp As Variant
ReDim temp(LBoun...
The following codes generate table row dynamically. I wonder if there are better ways of generating the same data. Also instead of manually coding the heading and the table itself, is it possible to code them with less codes without using the innerHTML function.

On the Internet, I found just such a wrapper for a standard STL-container std::unordered_map. I am interested in your opinion about its expediency and especially the expediency of redefining the operator().

To practice my c++ I decided to implement a simple Kafka producer to wrap the producer in c in librdkafka library. I just want to get your opinion on the way I have implemented teh default, copy and move constructors and make sure what I'm doing is safe.
Default constructor:

I am making a library which can use different auth mechanisms. I have abstracted the code within an interface:
interface Authenticable

public function getName(): string;
/**
* Based on auth type, return the right format of credentials to be sent to the server

* @param...
I am interested in learning how I can improve the speed of the code in this pygame file. I iterate over 6400 * 1800 * 3 elements of various numpy arrays here to apply noise values to them. The noise library I'm using can be found on GitHub here. All others are self-explanatory noise-maps.
I am c...
I wrote a program in pygame that basically acts as a physics engine for a ball. You can hit the ball around and your strokes are counted, as well as an extra stroke for going out of bounds. If I do further develop this, I'd make the angle and power display toggleable, but I do like showing them r...
