152334H··on The First Fully General Computer Action Model
holy crap, this is so good. How did it get buried?
152334H··on An AI agent published a hit piece on me
Thank you for the discovery.
152334H··on Dead Internet Theory
in effect, broadly anti-AI communities like bsky succeed by the sheer power of universal hate. Social policing can get you very far without any technology I think
152334H··on Light Mode InFFFFFFlation
> I’ve never met a person saying they hate books and wish they were white on black.

Wow. This is the most insightful statement I've read today.

It's finally clicked [U+2014] why I prefer e-ink to hardback, in spite of the alluring texture of plup across fingers.

It's because it should've been white-on-black, not black-on-white. It makes so much intuitive sense.

152334H··on Ask HN: How can we solve the loneliness epidemic?
It's branched from how I think about TFR. To merge,

- the common sentiment of "child raising is too expensive"

- the reality that wealth has drastically gone up

I think: okay, it must feel expensive for some reason. Probably because the work involved, despite not changing too much in an absolute sense, is relatively much pricier compared to all modern cheap sources of happiness.

Then, this notion of the cost-of-fun is easily transferred to general socialization & the loneliness problem.

152334H··on Ask HN: How can we solve the loneliness epidemic?
From my perspective, the issue is quite simple: progress optimizes everything other than the cost of human labor. Socialization, as defined today, inherently requires human labor, and thus falls under the Baumol effect.

The 'loneliness epidemic' is merely the result of weakening demand, owing to a slew of low-cost alternatives. Thus, we end up with two options,

1. automate the social experience

2. accept that the comparative cost of socialization will grow higher forever

For some reason, the vast majority of humans in the 21st century are interested in morally rejecting (1), thus ensuring (2) as an outcome.

.

Note: this is not to say I reject the notion that individuals can be helped. I think most comments in this thread are quite healthy, even as they narrowly focus on the individual case.

But it is rather impractical to adopt a positivist "how you can help" framing to address the epidemic at large. While certainly instrumentally useful, it is necessarily unlikely for the same traditional solutions to loneliness to spontaneously 'gain influence' against what has thus far been a gradual decline in their effectiveness and buying power.

152334H··on Solo ASIC tapeout on a budget: detailed write up
It is a bit misleading to say 'Solo', when TinyTapeout is involved.

Still clearly effortful work, though. I don't want to disparage it.

152334H··on Try to take my position: The best promotion advice I ever got
good observations of AIGC form here

Continually sad to see each day that the vast majority of users cannot classify

152334H··on Grok is enabling mass sexual harassment on Twitter
oai/gdm avoids the issue on their public facing products with broader default moderation thresholds, which can still be turned down explicitly via their APIs.

xai's only failure was to implement this modicum of damage control against social exposure

152334H··on 2025 Letter
note that the first chunk of the piece spends time to analogize SV to the CCP, in terms of its willingness to take attacks (of humor).

So, for your quote, a skeptical interpretation of the text may assert the author was merely praising SV in the same fashion one might appraise the party.

152334H··on 2025 Letter
> Beijing has been preparing for Cold War without eagerness for waging it, while the US wants to wage a Cold War without preparing for it.

great line

152334H··on Privacy doesn't mean anything anymore, anonymity does
thank you. absurd no other comments noticed
152334H··on If a Meta AI model can read a brain-wide signal, why wouldn't the brain?
+1. The article itself hides it well, but the draft paper linked at the end is clearly 100% AIGC.

And the paper is clearly the ancestor to the article itself, based on the date (5dec -> 11dec)

152334H··on I do not want to be a programmer anymore
amazing meta-level joke spanning months of effort... all articles on the author's site are themselves AI generated, and the article purporting to bemoan the impact of AI is itself AI Generated Content
152334H··on Starlink is currently experiencing a service outage
what's supposed to be inferred from the link? I only see the homepage.
152334H··on Look Out for Bugs
Extremely funny post.

The author doesn't grasp how much of what they've written amounts to flexing their own outlier intelligence; they must sincerely believe the average programmer is capable of juggling a complex 500 line program in their heads.

152334H··on OpenAI Leaks 120B Open Model on Hugging Face
They have a 20b for GPU poors, too.

I will be running the 120B on my 2x4090-48GB, though.

152334H··on Eleven v3
'was'. I departed almost half a year prior to v3's release this week.
152334H··on Serious issues in Llama 4 training. VP of AI at Meta resigned
VP of AI at FAIR, who is unrelated to the llama/genai team.
152334H··on Calculating the cost of a Google DeepMind paper
Is it free-priority based?

I was told by an employee that GDM internally has a credits system for TPU allocation, with which researchers have to budget out their compute usage. I may have completely misunderstood what they were describing, though.

152334H··on Calculating the cost of a Google DeepMind paper
You are correct on true H100 ownership costs being far lower. As I mention in the H100 blurb, the H100 numbers are fungible and I don't mind if you halve them.

MFU can certainly be improved beyond 40%, as I mention. But on the point of small models specifically: the paper uses FSDP for all models, and I believe a rigorous experiment should not vary sharding strategy due to numerical differences. FSDP2 on small models will be slow even with compilation.

The paper does not tie embeddings, as stated. The readout layer does lead to 6DV because it is a linear layer of D*V, which takes 2x for a forward and 4x for a backward. I would appreciate it if you could limit your comments to factual errors in the post.

152334H··on GPT-4o
thanks

152334H··on Non-determinism in GPT-4 is caused by Sparse MoE
just set up a desktop service to randomly open a paper once every few hours

if they're not too boring, and you're not doing anything important, you'll read it for fun

152334H··on Non-determinism in GPT-4 is caused by Sparse MoE
I agree, and really hope that Meta is doing something in that vein. Reducing the FLOPs:Memory ratio (as in Soft MoE) could also open the door to CPU (or at least Apple Silicon) inference becoming more relevant.
152334H··on Non-determinism in GPT-4 is caused by Sparse MoE
Thanks. I'm really no expert (:P) on MoE research; I just noticed what was written in the Soft MoE paper and felt a need to check.

The non-deterministic outputs are really similar, yeah, if you check the gist examples I linked https://gist.github.com/152334H/047827ad3740627f4d37826c867a.... This part is at least no surprise, since the randomness should be bounded.

I suspect OpenAI will figure out some way to reduce the randomness at some point, though, given their public commitment to eventually adding logprobs back to ChatCompletions.

152334H··on GPU Guide (For AI Use-Cases)
Strange. There seems to be no mention of vast.ai in the GPU Cloud Providers list, but they're definitely cheaper than all of the options listed.

Perhaps the writer kept them unmentioned in an attempt to reduce demand?

152334H··on Programming education, tacit knowledge and LLMs
> I think it's more plausible that teaching focuses on this surface knowledge because it's much easier and more legible, and looks and feels very much like "programming education" to someone who does not have actual domain knowledge (because other subjects are usually done in the same way), or who isn't thinking very much about it, and then similar problems and a notion that testing should be "fair" and "cover what students have learned" lead to insufficiently outcome-oriented exams, which then sets up incentives biasing students in similar directions.

And that's how you end up with CS students aceing theory exams, while completely flunking the coding exam...

> Computers are not at all human, in that they do exactly what someone has set them up to do, which is often not what they thought they were doing, while many beginners expect them to "understand what they meant" and act accordingly. Every simple-looking capability is burdened with detail: the computer "knows what time it is" (thanks to some nontrivial engineering with some possible failure points); the out-of-order CPU "runs just like an abstract in-order machine, but very fast" (until security researchers find a difference); DNS "resolves domain names to IPs" (but is frequently intercepted by networks, and can also serve as a covert backchannel); video codecs "make videos smaller" (but are also complex domain-specific programming languages); text rendering "is just copying bitmaps into the right places" (unless you care about Unicode or antialiasing or kerning).

Although people don't really encounter complex leaky abstractions like that as a beginner in coding. More likely, they'll encounter some simpler poor abstraction like Scratch blocks not being all fully composable in an intuitive fashion, or a sheer wall of complexity (e.g. getting taught in Java/C for an introductory course)

152334H··on Align Your Latents: High-Resolution Video Synthesis with Latent Diffusion Models
I agree with that, but it's hard for me to get excited with the knowledge that it'll almost certainly be discarded and forgotten. I've seen too many papers that looked interesting from a theoretical perspective, but were simply never brought to the public because of the barrier of dev+training.

In this case, you need someone that can implement the method as described (hard!), and then you need someone with a setup better than a rented 8xA100 (expensive and not available on many cloud providers) to actually reproduce the model.

152334H··on Align Your Latents: High-Resolution Video Synthesis with Latent Diffusion Models
No model, no code.

About as exciting as Imagen-video, which was released eons ago.
