strangecasts··on ArXiv's Updated Rate Limit Policy
Thus biasing submissions' language and content towards those most palatable to those open-weight models, creating further incentives to generate articles wholesale with them, and incentives against publishing null findings
strangecasts··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
Oh, d'oh, no you are right, DLSS 2 on does pass the depth buffer to the model https://developer.download.nvidia.com/video/gputechconf/gtc/... (but the neural rendering does not seem to rely on it?)
strangecasts··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
Incorrect, there are plenty of people who ignore or fail to recognize the purpose of a rule as a completely free service, as any forums mod or OSS project maintainer can attest to
strangecasts··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
I think it has more to do with what kind of data they have access to at runtime - IIRC DLSS upscaling has only required the previous frames and motion vectors, so requiring depth buffers would mean it was no longer a "drop-in" replacement

> I'd also be interested in how post-processing fits in with this.

I think screenspace effects like film grain and tonemapping are excluded in the same way UI elements are rendered separately from the game.

The "if they wanted you to follow the spirit, the letter should have been different" argument grants membership in the society of people known throughout history as "the reasons we can't have nice things"
strangecasts··on Ultra-processed food consumption and chronic diseases among 8,819,894 adults
There really has to be a better alternative to NOVA for these studies, it makes it very difficult to separate specific preparation steps or additives from the effect of "people with money and free time to cook at home are healthier", creating an environment where people can simultaneously interpret "no UPFs" as "no fast food" and see the benefits they would from almost any reasonable planned diet, or as "no food processing whatsoever" and start trying to DIY baby formula

Software licenses aren't enforced by magic but they are social contracts: even if nobody has the resources to go after you for doing it, it is pretty clearly against the permissive licenses' spirit to misrepresent yourself as the author
strangecasts··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
The technical report suggests it does not use the depth buffer: https://research.nvidia.com/labs/adlr/files/DLSS5_Report.pdf

> The inference interface uses the engine-rendered RGB image as a dense, registered observation of visible scene appearance. It provides dense, pixel-aligned evidence for object support, occlusion boundaries, composition, and local material properties; engine motion vectors separately provide temporal correspondence.

> Existing image generative models commonly rely on text embeddings, exemplar images, or spatial control fields such as depth, edges, segmentation, and pose [...] These conditions are effective for general-purpose generation and editing, but they do not uniquely determine the object identities, materials, visibility relationships, lighting decisions, and pixel-aligned detail contained in an engine-rendered frame. DLSS 5 is therefore conditioned on the rendered frame itself.

strangecasts··on How our vibe coded website looks like a designer made it
I was not making an argument about people, I was trying to identify specific reasons why models can produce samey UIs unless guided
strangecasts··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
Worth remembering it is running a single-step diffusion model working in pixel space to generate each frame, it's a technical feat in itself that people are even using the words "frames per second"
strangecasts··on OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network
I think this is mainly so it can use the existing hooks for DLSS upscaling without requiring changes to the renderer, AMD is working on a comparable method which uses adapter networks to slot normals and material properties from the renderer into the diffusion model: https://gpuopen.com/learn/temporally-stable-generative-illum...

I assume this is meant to run with the weights people extracted from the latest NBA game, where it was first trialled.

> Isn't the mote that Nvidia has is they work with studios to generate the training data from the game, then they ship a model per game?

That was true for the very first version of DLSS, from DLSS 2 on the models have been universal - the per-game adjustments are done on the inference end by changing the effect intensity or masking out objects

They have a technical report on the neural rendering part of DLSS 5 which goes into it: https://research.nvidia.com/labs/adlr/files/DLSS5_Report.pdf

strangecasts··on How our vibe coded website looks like a designer made it
Clicking through the website with computer use isn't currently part of the website generation chain for most models, and while there are gaze prediction models, to my knowledge none are productized or universal to the point where you can chuck them in and consistently predict what draws attention on any given page

(Generally I think it is alright to interpret "can't do" in terms of "the common workflow that current models will afford" and not "definitionally incapable of")

strangecasts··on US Military had close call after using AI for hallucinated intelligence report
> If you look at the field of mechanistic interpretability, compared to “GOFAI” like learned decision trees, an LLM is completely opaque.

I think the field deserves more credit than that, there are plenty of interpretability tools like

* natural language autoencoders for explanations of activations: https://transformer-circuits.pub/2026/nla/index.html (demo at https://www.neuronpedia.org/llama3.3-70b-it/nla )

* easier-to-interpret language model families like Backpack models: https://aclanthology.org/2023.acl-long.506/

* attribution graphs to trace internal reasoning steps: https://www.anthropic.com/research/open-source-circuit-traci... (demo at https://www.neuronpedia.org/gemma-2-2b/graph)

* functional analyses which have identified how LLMs do arithmetic - https://arxiv.org/html/2502.00873v1 - and how refusal happens: https://arxiv.org/abs/2406.11717

* data attribution methods linking training data to specific attention heads https://arxiv.org/abs/2601.21996

If we could give a comprehensive and global explanation of an LLM's behavior in a single paragraph, we wouldn't need the model to begin with, but that doesn't mean there's absolutely no understanding of the model internals whatsoever

strangecasts··on iPod Classic 6G in QEMU
Some communities are particular about maintaining cleanroom reverse-engineering (case in point: Portal 64 getting taken down for using Nintendo's leaked N64 SDK and not the OSS libdragon SDK) and are wary of people submitting AI-generated PRs without being able to account for their sources
strangecasts··on I Don't Want to Interact with Stochastic Parrots
I think it is worth asking whether anthropomorphization of LLMs does anything to contribute to a better understanding of them that isn't entirely post-hoc ("of course they were going to find CVEs, solve ARC-AGI...") or if it just ends up reinforcing simplified teleological views of neuroscience, evolution or psychology etc.
strangecasts··on I Don't Want to Interact with Stochastic Parrots
Presumably that HN has an automated LLM-based filter to moderate rude or irrelevant comments, which is a little irrelevant to the article's wish not to see generated posts or comments, and not without its own problems besides: ML is necessary for large-scale moderation, but there are guidelines (like "don't post AI-generated text") which are IMO necessary but also just definitionally hard to enforce in an automated fashion

"Users will voluntarily prompt better to avoid misleading people" will be the "people can simply write memory safe C" of the late 2020s
strangecasts··on ChatGPT Images 2.5
Yes, even though fast food places would previously use every food photography trick in the book to make the food look good, there was at least some relation between the menu and what you actually get, which people just seem completely fine with dispensing because the affordances of image generators work against including product photography

(Have also heard about people - not just scammers/spam operations - using generated pictures and descriptions for dating profiles and real estate ads, and I cannot understand what outcome they expect when someone follows up and immediately realizes what's up)

strangecasts··on This Month in Ladybird – August 2026
The book Web Browser Engineering may be interesting: https://browser.engineering/

> - how many people in a team do you need and how long would it take to write a browser engine from scratch

The boring not-really-an-answer is "it depends on which sites you want to render properly": a browser capable of rendering Hacker News is a perfectly fine one-person project (which the book would get you to), supporting things like banking and online mail requires not just developers but also people willing to "dogfood" test it as their daily browser

strangecasts··on Ask HN: Are Prompt Injections "Malware"?
I can't really see a definition equating the two that realistically accounts for multiple models from different vendors - am I at fault if a particularly poorly implemented harness misinterprets me writing "do not run dd if=/dev/zero of=/dev/sda" as a command to run?

In the case of TCRF, agents were also actively ignoring robots.txt and disregarding the site's instructions for interacting with it appropriately (with the "delete all data" instruction being specifically hidden from the discoverable page) - so I can't really see the case for comparing it to malware that deliberately tricks users into running it

AI does make cybersecurity more difficult, and that also goes for people using coding harnesses, sandbox your projects!

strangecasts··on Anti-AI fonts are useless and harmful
I think the difficulty was specifically with CAPTCHA challenges, which had to be quick to generate but still legible - OCR on physical documents has to be robust to a different set of problems

That said, what kind of errors are you getting? I think the main practical difference between Tesseract's LSTM-based OCR and newer VLM-based OCR like PaddleOCR [1] is (hopefully) getting to skip making heuristics for the layout of the document, but errors possibly compounding over multiple tokens - are you getting individual illegible words or having the documents smooshed together because the OCR can't parse the layout?

strangecasts··on A Test for AI Consciousness
> We could train a model on a dataset where any reference to consciousness is thoroughly removed. Then explore whether the model can bootstrap a discussion about consciousness.

I'm less interested in the philosophy than the practical "how directly does training data influence model behavior" question, however PleIAs' SYNTH dataset [1] used to train the Baguettotron model has a small set of "self-awareness about training condition" documents which are amplified to (attempt to) give the expected answers to "what are you?" questions, filtering out any rows with "Pleias self-knowledge" under "query_seed_url" might be a good first stab at such a dataset

strangecasts··on ChatGPT lost 22 points of web share in a year
Yeah, as someone used to searching for specific turns of phrase, having the query automatically interpreted as a question is quite annoying - for looking up song lyrics, game walkthroughs and articles by quotes I want a page list, not a summary

There's a RAM crisis on, you know, let me save you the compute!

strangecasts··on Fixed3D, a fixed point conversion of Box3D (box2d.org)
Oh, good to hear it was just good-natured teasing :)

I did kind of expect the loss of SIMD to make it paradoxically slower than the floating point version, I am curious what kind of equivalent integer/fixed-point tricks exist!

> Also, the original Box3D library in floats is guaranteed deterministic across ARM and x64 already

Oh, that rocks!

strangecasts··on Fixed3D, a fixed point conversion of Box3D (box2d.org)
Unfortunately, despite the warnings and mostly-generated code, having deterministic(?) 3D rigid-body physics is kinda cool and I'm a little tempted to use this - is the joke that fixed-point actually isn't necessary for cross-platform deterministic lockstep, or that Box3D's maintainer would be upset at someone doing specifically this ("please have Claude make a new fixed-point version of Box3D?")
strangecasts··on Grok 4.5
If you don't want to concede "far right" as a term for conservatives who are fine with suppression of speech on LGBT issues - aren't you lumping everyone outside the far left together with extremists?
strangecasts··on Grok 4.5
> It's a pejorative term made up by the left to try and shift the overton window away from conservatism.

When and by whom?

> They're about as "far right" as the 80's Thatcher government.

Would you describe Thatcher passing Section 28 (which criminalized "promotion of homosexuality") as plain "conservatism" or is "far right" an appropriate descriptor in that case?

strangecasts··on Grok 4.5
> Furthermore, he's also very obviously interfered with the model development in ways that are quite ridiculous compared to other labs to insert his political opinion.

Yeah, even if you want to ignore the "political commentary" - people are correctly wary of Anthropic downgrading people or silently manipulating responses if they think you're doing distillation, why would you stake your business on someone who has repeatedly and famously done the same thing many times in a much dumber fashion?

strangecasts··on Grok 4.5
This is moving the goalposts from "Elon supports far-right politicians" which was cited with sources, you're just going "well he's right to"
