I've seen many healthy technical disagreements; often leading to new insights coming to light, assumptions being made explicit, everyone leaving with a better understanding, sometimes resulting in one party conceding, sometimes resulting in a compromise. Guess it requires a certain level of maturity / people arguing in good faith.

My point is it's still useful to have a somewhat authoritative place to cite (high quality) blog post level content. arXiv has formatting requirements and doesn't go down like random personal sites.

> a LaTeX PDF can launder epistemic status

True to a certain extent, although something people are aware of and they can judge the content themselves (hopefully).

I don't have access to the DeepMind demo, but from the video it looks like it takes the idea up a notch.

(I don't know the exact lineage of these ideas, but a general observation is that it's a shame that it's the norm for blog posts / indie demos to not get cited.)

"Tell HN: Viral Hit Made by AI, 10M listens on Spotify last few days" [1]

> I couldn't resist putting a face to this gem.

After saying it is AI:

The author has stated it's AI in their YouTube video descriptions [1] [2], e.g.

It has gone viral in last few days, due to TikTok and YouTube Shorts.

10,000,000 listens on Spotify - https://open.spotify.com/track/0HI7kOxEfnSMD2Z27BJnJN

There's various other YouTube videos of it with millions of views.

I heard of it myself through YouTube shorts, and after a few listens suspected it was AI.

Yep this kind of thing can happen. I found and reported incorrect gradients for Apple's Metal-backed tensorflow conv2d in 2021 [1].

(Pretty sure I've seen incorrect gradients with another Pytorch backend, but that was a few years ago and I don't seem to have raised an issue to refer to... )

One might think this class of errors would be caught by a test suite. Autodiff can be tested quite comprehensively against numerical differentiation [2]. (Although this example is from a much simpler lib than Pytorch, so I could be missing something.)

- Convert the whole codebase into a string

- Paste it into Gemini

- Ask a question

People seem to be very taken with "agentic" approaches were the model selects a few files to look at, but I've found it very effective and convenient just to give the model the whole codebase, and then have a conversation with it, get it to output code, modify a file, etc.

Nice synergy here, the lineage is: Karpathy's nano-GPT -> Keller Jordan's modded-nanoGPT (a speedrun of training nanoGPT) -> NanoChat

modded-nanoGPT [1] is a great project, well worth checking out, it's all about massively speeding up the training of a small GPT model.

Notably it uses the author's Muon optimizer [2], rather than AdamW, (for the linear layers).
