hhhhhhh homework in the summer ?
Although I know in Japan they give them such horrors

It sounds like you’re just beginning you journey in higher maths

I'm actually old and lurked in university stuff for a long time and dropped out of engineering in university and started with math all anew, yet at the same time I'm still a beginner.

Hmm. Where did the question in OP come from?

I don't exactly remember How I started thinking about the "distance between plane and a point formula", I think I stumbled upon it while organizing my old bookmarks. Tried to make a proof, and in the process that question came, and when I couldn't solve it on the fly I though like "it's so over for me". Then ChatGPT also got it wrong and was like "It's so over for mankind". And I ended up making this post to share my despair. Actually many answers were eye opening.

How first reading felt:

How the second reading felt at the beginning:

How it ended up:

What is {y∈V | O(y) = 0} ? If the plane doesn't pass through $0_V$ then how would that 0 be the image of some point ? Most likely you're using something from linear algebra that I didn't learn in my course (I didn't learn projection I think, only examples when learning matrices).

DUH! If this was math.stackexchange I'd choose this as answer

~~I tried again, I don't find mistakes in your statements, I just don't see how they make up for "instant in-mind proofs" for the problem~~ I think I see it now, nevermind. Your got a very good visualization for 3D CanadPlus. It seems so intuitive that "the set of points that map to H with orthogonal projection is a straight line", but do you happen to have a pocket proof for that ?

I couldn't make sense of the first paragraph, are you sure it is right ?

~~
fyi: the orthogonal projection of a point P into a plane is a point H of that plane such that for any other point A of the plane: (PH) is orthogonal to (HA). One might think that finding that "(PH) is orthogonal to (HA)" for one such point A of the plane is enough, turns out it is not.
luckily an easier criterion exists: H is the orthogonal projection of P if (PH) is parallel to n the normal to the plane.

retro computing was so chad

ADHD driven hard work could never disappoint huh?

But what was the advantage of QuickBasic? Weren't C++ and Javascript around at the time? I only hear about them in this context

impressive, I'd like to ask abou stuff like how long it took you and stuff. But in this discussion I'd like to mention that I didn't use any complicated terms, only orthogonal projection (middle school) and perpendicularity (elementary school).

my lazyass had it hard to put correct labels. But judging by how many people ignored the proble an are just scolding me for using AI, fair is fair.

 

I think 3D geometry has a lot of quirks and has so many results that un_intuitively don't hold up. In the link I share a discussion with ChatGPT where I asked the following:

assume a plane defined by a point A=(x_0,y_0,z_0), and normal vector n=(a,b,c) which doesn't matter here, suppose a point P=(x,y,z) also sitting on the space R^3. Question is:
If H is a point on the plane such that (AH) is perpendicular to (PH), does it follow immediately that H is the projection of P on the plane ?

I suspected the answer is no before asking, but GPT gives the wrong answer "yes", then corrects it afterwards.

So Don't we need more education about the 3D space in highschools really? It shouldn't be that hard to recall such simple properties on the fly, even for the best knowledge retrieving tool at the moment.

Does it really work as explained and is the script really safe to download?

Sorry for the low effort post, I just want to know if this works. ChatGPT 4 is actually fun to use, I mean chatting with it about math is really fun and constructive.

The comments on the linked Youtube video suggest so, but I remember ChatGPT telling me that NASA doesn't share their optimized Fortran compiler.

 

Here sucks is in the sense of suckless philosophy, I don't think everybody likes the suckless movement but I've seen that many people, me included, don't like how modern web apps look like (messenger and tiktok are like the worst). So if I want to make interactive web apps, what are the better technologies to not make the web shittier ?

 

I can't see it happening tbh, but like the USA government discussed putting restriction on AI development, I think OpenAI or some other companies asked them to do so!? And there were short/reels of high profile developers hyping out the fact that "we don't know what we're doing", and one of them quit his job. So why is all that hype? Is the "Matrix" route actually a possible future ?

 
 

tried yt-dlp, with browser cookies. Tried the developer tools trick too (network serction). None has worked

 

I mean the whole 50GB model. All I can find is people trying it in Huggingface. Only person on the internet, who actually downloaded and tried the model using their own Hardware locally, that I can find is this: https://youtu.be/6axAY9NV1OU . But he tried the 1B version (it is only 4 or 5GB of size), I expected there would be a Youtube channel or Discord servers or 4chan boards specifying in these kinds of tests but so far I'm out of luck.

 
 

 

The thumbnail image is a screenshot from a Youtube video, for a song. the lyrics in gold color are Youtube closed captions, they look cool and stylish right? This is common in videos of 4K scaled anime openings. Can I get these offline? I know I can download videos using yt-dlp, and include subtitles in the container using the --embed-subs flag, I think you can also download subtitle files in vtt extension, but VLC can't read them I think.

I didn't include a link cuz it might become a hustle for dbzer0, but since some are asking here you go: https://www.youtube.com/watch?v=CXzoiiZo5LA
https://www.youtube.com/watch?v=StLX4kITjWU

there were better ones (Kaguya-sama openings) but I can't find them anymore on Youtube, stupid copyrights, thus my obsession of hoarding what I like

Update: @Majestic@lemmy.ml provided the solution,
1- download the subtitle file in vtt format using yt-dlp:
yt-dlp --skip-download --embed-subs https://youtu.be/5i3pX-2NLKk?si=waYB6Jv4d6gxsVuh

2- use Subtitle Edit's batch converter tool to convert the vtt file into .ass format

3- now just import it on VLC while watching your downloaded video, the subtitles will appear in the same styling as on Youtube, additionally you can embed them to the video container using ffmpeg
