SO, it started quite nicely with a fully working program. However nearing the end... or at the end of my programming experience or asking it to program something for me, it wrote in some nasty nasty screen flickering shit. I couldn't stop it and it quickly just froze my screen where the only option was to push the button. I tried it a second time to confirm, but this time I was able to quickly go to a different CLI window and kill that sonobabich. Here is what it came up with in case you want to try it. maybe it only screws up my computer:

import os
import cv2
import numpy as np
import time
import tkinter as tk
from tkinter import messagebox, filedialog

def threshold_to_black(image_path, duration):
    original_image = cv2.imread(image_path)
    
    if original_image is None:
        print("Error: Could not read the image.")
        return

    height, width, _ = original_image.shape
    gray_image = cv2.cvtColor(original_image, cv2.COLOR_BGR2GRAY)
    steps = duration * 10  # 10 frames per second

    for i in range(steps + 1):
        # Calculate the threshold value (0 to 255)
        threshold = int((i / steps) * 255)
        
        # Create the thresholded image
        thresholded_image = np.where(gray_image < threshold, 0, 255).astype(np.uint8)

        # Resize the thresholded image to fill the window
        resized_image = cv2.resize(thresholded_image, (window_width, window_height), interpolation=cv2.INTER_LINEAR)

        # Display the thresholded image
        cv2.imshow(window_name, resized_image)

        # Wait for a short period to create the effect
        time.sleep(0.1)

        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

    # Display the final black image
    cv2.imshow(window_name, np.zeros_like(thresholded_image))
    
    while True:
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    
    cv2.destroyAllWindows()

            if total_duration > 0:

that’s not what a virus is

[–] [email protected] 25 points 3 months ago (1 children)

I'm sorry, but it seems like you're playing with tools and code you don't understand. First, this has nothing in common with a virus. That is either a click bait or you don't understand what it is you are looking at. If it crashes your computer, it is simply badly written code. Any programmer has done something similarly (in their area of domain, ie not necessarily able to crash a computer).

For the next time, I would recommend you to use the AI to explain the code and ask questions about it.

[–] [email protected] 6 points 3 months ago

Exactly. This is as much a virus as the program I wrote as a first year CS student that rebooted the computer due to a bad pointer dereference was a virus. (That one would probably just segfault today, but I started back in the DOS dark ages . . .)

[–] NeoNachtwaechter 20 points 3 months ago (1 children)

You don't need AI. Take some basic programming courses.

I once heard a cook say that cooks who use salt mills aren't cooks.

I'm really tempted to say the same thing about programmers that use llms to code.

[–] Plopp 22 points 3 months ago

Yeah, programmers who use LLMs to code sure aren't cooks.

[–] NeoNachtwaechter 2 points 3 months ago

We don't know about all programmers, but we know one at least now.

I knew my clothes were the issue.

[–] [email protected] 3 points 3 months ago (1 children)

Every time I click on a clickbait title and KNOW what’s coming (bullshit is what’s coming), and yet I do it anyway and get the expected result. Shame on me and that should teach me.

LOL. Hey, it's a really bad script that locks up your computer if you run it. So it's not nothing!
