I'm writing a tech demo of an idea I had about alternative GUI programming techniques. so far I had been using xcb and everything is going fine and the idea is working but I was thinking about adding wayland support before releasing the code. I know wayland has a compatibility layer with x11 but considering I'm not doing anything crazy, mostly just drawing rectangles and text, and handling events, I thought "how hard could it be to add native support with a few ifdefs here and there". however, it doesn't seem like there is much documentation on how to write applications for wayland, and most places just tell you to use gtk or kde or some other high-level framework

tl;dr my question is, is there something like this official xcb tutorial but for whatever the wayland equivalent of xcb is?
https://www.x.org/releases/X11R7.7-RC1/doc/libxcb/tutorial/index.html

Looks like maybe XDG-shell and libwayland-client. [^1][^2][^3]

huh, apparently it doesn't have drawing commands like x11, you just render client-side. I guess I will just use cairo then
but man it feels like a regression, as antiquated as it was, I liked that, in theory, you could use pure x11 programs through a network and the remote application would just send you the drawing commands to be rasterized locally

they're making "AI GPUs" now. it's not a GPU at that point it's an AIPU. we don't call CPUs "central GPUs".

they should call them AIPUs and market them as that.

>>31577
it is hard to tell without more information; computer vision for example is considered AI but uses different hardware (conventional GPUs) than chatbots. or maybe it is a GPU with additional hardware for AI features, or whatever. your CPU has a lot of stuff in it besides the ALU and the decoder, and yet we still call it a CPU

the real discussion is that huawei should focus on euv development and stop trying to cope with duv designs

>they should call them AIPUs and market them as that.
They are though??? It's right there in your picture. Huawei called it an inference card.

Have heard the term LPU, language processing unit from Groq.
And NPU used by Microsoft.
Seems there's just not a standard yet.
Language seems over restrictive, NPU sounds closer.

>>31597
AIPU too clunky to say, IPU/inference card or NPU will prolly win in the long term

Use snap install and do a lsblk, then stab out your eyes

So, i tried installing CachyOS today. Live CD looked like a standard "Arch for lazy and/or stupid people" kind of thing… At first glance. First problem i noticed, was that with a 2-and-something GB image here was no offline install option. Yeah, weird, but it's 2025, so i could theoretically forgive that. Well, it was actually a problem for me, since government is doing some weird shit with the internet, a lot of mirrors were inaccessible, but that's not the point. So, i was going to set up some VPN or proxy, but then… Something happened. Something truely, minblowingly terrible.

The idea is to use a patched build of chromium for the mpp. [^1]
This should alleviate the CPU pressure from recording the small built in.
It should be able to run an unrecorded 1080p separate monitor for references too.
My concern is running the un-GPU-accelerated whiteboard.
Maybe krita could work, which has partial GPU-acceleration?
But this would seem to be a little less a convenient usage of the platform.
And I'm not sure if it would work anyway…
Anyone with experience on a RK3566 think it could handle it?

There's apparently not really negotiation on the encoding.
It's entirely possible that wyzant doesn't support the hardware encoding.

AI markets are already saturated lmao, no growth to be seen

What is the possibility of biological agi? Im mostly convinced that machine agi may not happen due to the extreme difference between silicone and biology but what about the biological method? Would organic computers bridge the gap enough to the point agi could be possible

>>31572
I mean at that point you just want an autistic kid that knows VIM

ai video gen economics are nonsense if you think about them, sora 2 generates a video for a user, said user reposts it on tiktok, insta and xitter, monetizes it, and gets a marginal cut. hosting costs are pennis on the dollars for a social network, but generation price is like 5 dollars at least per video (in the unlikely event the video was created in one shot, most likely it's significantly more expensive because the user kept cranking the lever to get something acceptable), so in essence openAI is subsidizing meta and tiktok, no wonder theyre so invested in making their own social network. so in the near future they're not going to let users download AI generated content, it'll have to be posted in the same place it was generated, because social media is technically funneling money away from AI providers.

>>31585
No way inference is that expensive unless your amortizing training costs into it.


File: 1760630271687.pdf (8.23 MB, 57x255, Dr. Joseph Slavit - The Ne….pdf)

 

I'm a volunteer for Marxists.org. Finding forgotten gold articles from 100 years ago and sharing them with the modern world is my jam. The problem is that they're often microfilm scans that are a pain in the ass to read, so I have to transcribe them - which rarely goes smoothly with my OCR software. A lot of the time I have to resort to typing everything out by sight, which as you can imagine takes forever.

That OCR software is ABBYY FineReader 15, said to be the best when I pirated it right before the big machine learning breakthroughs. Is "AI" able to work magic for optical character recognition now?

Attached is a book-length article I'd like to transcribe. It's mostly too fuzzy for FineReader 15 to handle. I was originally going to call on /leftypol/ to help me transcribe it by hand, but I thought I'd ask /tech/ first to see if a machine can do it after all.

TL;DR: help me transcribe this plz.

Better yet do encode image by image, but not in a stupid way:

def render_pages(
    src_pdf: pathlib.Path,
    resolution: int,
) -> List[bytes]:
    pages = []
    with Image() as images:
        images.resolution=resolution
        images.read(filename=src_pdf)
        images.depth=8
        images.colorspace="gray"
        for image in images.sequence:
            compressed = Image(image=image)
            compressed.format = 'jpeg'
            buffer = io.BytesIO()
            compressed.save(file=buffer)
            pages.append(buffer.getvalue())
    return pages

>>31586
I'll admit that I have no idea how to use that code or what it means, but thanks for creating the script to transcribe this! There are a fair amount of errors, but not as many as ABBYY would generate - it seems like the LLM is a lot better at cutting out all the extraneous exponents and apostrophes that ABBYY would pick up from the film grain.

The downside from the LLM is that you sometimes get some true bizarre hallucinations. Like this one in the opening sentence of part IV. Here it is typed out by sight:

In the first article we introduced the reader to Comrade William English Walling, the "new" Duehring, who proposes a "new" Socialism based on "new" methods and principles.

And this is what the LLM spat out:

In the first article we introduced the reader to Conrad Williams*. [*Footnote: Not William, as given in the heading. Editors.] Dorothy, who proposes a "new" Socialism based on "new" methods and principles.

To clarify, there are no footnotes. The AI just totally made that up somehow.

>>31590
>no idea how to use that code or what it means
Well, that's a little too bad. I'm not exactly sure how to run it on Windows either. But it sounds like your existing solution is maybe good enough?

>true bizarre hallucinations
Yah, one of my other runs (maybe the one with the weaker model?) got it repeating "to my knowledge" a hundred times and monotonically decreasing the column width until it was just a word or part of one for one article.

>>31591
>But it sounds like your existing solution is maybe good enough?
I have dozens of hours of experience using it, which helps a lot. ABBYY also has a lot of PDF image editing tools built-in to deskew the text etc., so it looks like I'd be processing through ABBYY anyway before running the images through Tessaract or an LLM. Severely grainy or unevenly exposed images still give it a lot of trouble through with random apostrophes etc. that are a chore to manually remove.

I thank you again for transcribing the Slavit text for me though. It looks good enough that manually correcting it wouldn't be too bad. We'll see about that though, maybe the hallucinations will be so severe I'd have to verify every sentence.

The ultimate solution to this problem will be to get New York University to take the original crinkly newspapers out of storage and scan the broadsheets properly. Which the publication definitely deserves, but it's a huge ask and I'd like to be able finish my William English Walling complete works project (plus polemics aimed at him) before I dive into that.

>>31592
Good luck with your endeavors then.

>William English Walling
This seems like a very interesting character and project.

When the fuck will somebody use Python to script a VPN protocol out of for a full tunnel client w/ access to iptables w/ default setting at "strict"? Plus run it on custom STUN servers, uses 10.8.0.53 instead of 8.8.8.8 (Google)/1.1.1.1 Cloudflare)/9.9.9.9 (Quad9) and blocks any connections to them for a fine-grained DNS control, and fully self-hosted w/ local only control. Everything else is too insecure. Oh, and also

Isn't "office work" most prone to bullshit jobs in the first place. Ripe not for automation by AI, but for erasure.

>>31217
Well offices are a property value thing, make buildings where hundreds of people do shit that could've easily been done from home by one gal with linux on her laptop that knows bash script, and you have a commercial building, with all the zoning laws and tax implications that entails. And that's profitable enough that you can pay someone to be the "senior stapler inspector" or "blockchain synergy consultant."

>>27264
but it doesn't automate the office jobs though. because it gets shit wrong a lot. so in reality, at best it's used as a tool by a human being who has to double check all of it's work to make sure it's correct. and office work isn't like work on an assembly line where in theory there is an unlimited amount value you could produce were you not limited by your own body. in any given day there is a finite number of human to human communications tasks that have to be done by an office worker (and are the core of most of their jobs) which put a hard cap on the value they produce in a day and then they just play minesweeper or whatever and do their best to look busy

I've started making regular trips into the woods near my house, down a natural stream because it's the lowest part and creates a natural trail through what is essentially untouched forest and it's extremely nice to be out there and just center myself. There's deep water at some points so I've taken to just hiking in completely barefoot for about 2km.

It's become my new favorite hobby, you're not bored, you're not anxious, you're not worried about what people think, you're not in society, you don't have technology, any negative emotion evaporates about 1-2 hours in. The worst part of the entire thing is the walk back to my house. If it wasn't switching to winter I think I would just bring a tent out there and start living out there.

Why isn't it widely adopted yet? It's much better than AVIF since it's actually designed for still images, and Apple supports it natively on Safari and Photos. What's Google's endgame by killing work on support for it in Chrome?

Competes with webp. Think that's about it. A lot of programs do support it but chrome refusing is the main banana peel on the road.

nothing is sufficiently better than good old JPEG to actually dethrone it. what we should do is actually implement the full JPEG spec, which has a bunch of neat features like pyramidal compression and range coding

>>31542
Many websites already use webp or avif.

In the recent years, more and more platforms at starting to introduce age verification trough external services like Persona. The most recent one, being roblox, which introduced ID age verification not so long ago. We also have cases like Facebook and Linkdin. But it is just the start. Probably, soon more and more platforms will introduce restrictions and age verification trough ID.

Now the question is, how would one bypass these tools? Fake IDs, if so, how good they should be? Or is the technology even working? All the questions surrounding this are encouraged.
3 posts omitted.

I know from a friend's friend that you can use an image generator language model and photoshop to make fake photos of IDs to get around this, you just have to let your email account associated with the service's account "cook" first (e.g. let big data fingerprint it by watching youtube and creating general activity on it) so their algorithm does not recognize it as fraud

Since this thread was last bumped things have gotten worse.
The thing that is on my mind is how would one run a site without having to follow such laws.
Like I want to run my own porn site which is the most risky category.

this is very common if you are overemployed and want to have two different CVs. it's not "anonymously" just not tied to a real ID.

How about a webring instead? If a bunch of people making smut just link to eachother, there's no platform to be forced to do this to begin with.
