Vlad Feinberg's personal blog at vladfeinberg.com covers ai, programming and data. Since 2019, 5 different Hacker News readers have linked it 22 times, most often “Gemini Pretraining [slides] [pdf]”. It is still writing: the last post was on 2026-05-10, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link the author's slides from a 2025 Princeton talk, shared in a thread on Gemini Flash pretraining. The comment only gives PDF and X links, with no remarks on the writing.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
https://vladfeinberg.com/ I mostly post about stats or programming topics. I only really try to put something up if it's a particularly hot take on a useful topic, like * a reduction from causal to statistical inference https://vladfeinberg.com/2019/12/01/metaphysics-of-causality... * an exploration of what the best way to listen to experts is https://vladfeinberg.com/2020/01/05/stop-anytime-multiplicat...

HN discussion"Ridiculous" is not a word I'd use... sometimes symbolic derivatives are intractable, in which case complex step derivatives provide high-precision numerical derivatives which are otherwise unattainable. https://vladfeinberg.com/2020/07/05/discrete-residues.html

HN discussionI think the problem with observing interventions is it will result in impractically large sample complexity to derive the same causal conclusion as causal calculus armed with assumptions of DAG structure. I think metaphysically speaking the approaches (observing interventions vs causal calc) aren’t meaningfully different in terms of inferences you can make with infinite data, see my similar observations to yours: ht…

HN discussionI was hoping for this take—-of course LLMs have an internal model, and we can externally verify how accurate it is statistically. And the more you train it the better it gets. And for discrete spaces you might even get a perfect model eventually with nonzero probability. Since you mentioned different layers, one question to ask is if your poetry example is “just a combination of existing rare patterns,” one that’d b…

HN discussionI ended up needing this so often for graph processing, and for values which might be inexact if using floating point, that I saved the formula in a blog post. https://vladfeinberg.com/2020/03/07/subset-isomorphism.html The formula can be "oblivious" to the final size of the matrix too, which is helpful if you're doing some sparse ML training on edges (e.g., GNNs).
