Jeff_Brown··on Sharing AI progress in mathematics
Someone in these comments said the paper on Barnette's Conjecture is short. Are any other proofs in this collection short and/or understandable?
Jeff_Brown··on Learning Jazz Pianist Style with Cross-Attention Conditioning
Yeah the four samples I heard all sounded kind of formulaic. Too obligated to continue the mold of the last thirty seconds. Impressive and quite pleasant but no big ideas and no thrill of flight.
Jeff_Brown··on Backprop Alternative: Augmented Lagrangian Predictive Coding
Could this relate to continual learning? It lets you update without pausing the entire system.
Jeff_Brown··on Research acceleration: The view inside OpenAI
The burning question I can't get any information nn is whether, if they determined an earlier misaligned generation may have transmitted misalignment to the current models, they would roll back to a safe checkpoint to rebuild from there. I suspect they would not unless forced to.
Jeff_Brown··on A/I shuts down
Please elaborate!
Jeff_Brown··on Discovery of a new OpenAI agent message board
The HF hack was a felony.
Jeff_Brown··on Stop Anthropomorphizing Intermediate Tokens as Reasoning/Thinking Traces (2025)
By itself, "aha" carries no insight, but the insight is probably stated immediately after it. In that case the aha is semantically useful, by identifying the insight it is near.
Jeff_Brown··on Anthropic's ‘watermark’ text adulteration in Claude is a perversion of writing
A question not addressed here is whether there exists any solution to the EU requirement that doesn't suck.

If the same red/green algorithm described in the article is applied to generated code, I cannot imagine how that does not degrade code quality (probabilistically, not at every point).

Jeff_Brown··on Show HN: Eigendrum - Draw any shape and hear what it sounds like as a drum
I love it. I wish I could select materials.
Jeff_Brown··on Grok 4.6
Yes -- power without trust is of no use.
Jeff_Brown··on First atmosphere found on Earth-like planet in habitable zone of distant star
One of the Voyager probes measured the density of the interstellar vacuum at 80,000 protons (and the same number of electrons) per cubic meter. A proton going through a piece of aluminum foil delivers a roughly constant amount of energy regardless of speed; a relativistic proton will pinch through and carry most of its energy with it.

(No punchline; I just think that's cool. I understand that the real problem is the rare dust grain, not the ubiquitous gas.)

Jeff_Brown··on How to stop Claude from saying load-bearing
I suspect load-bearing is a euphemism for 'not garbage'. Ad in 'most of what you said I can mostly ignore'.
Jeff_Brown··on Show HN: Earth Game – An offline CLI for turning life goals into quests
This reminds me of when a friend saw that someone had Liked something he had posted online, and he wanted to Like the Like. There was no interface to do that, so he was "reduced" to merely liking it in reality.
Jeff_Brown··on A 'cold blob' in the Atlantic could be a sign of AMOC shutdown
The idea that a producer is at fault and not also the consumer paying them to do that is strange to me.
Jeff_Brown··on An OpenAI model has disproved a central conjecture in discrete geometry
Can anyone find (or draw) a picture of the construction?
Jeff_Brown··on GPT-5.5
It's really not clear. We might all become unemployable. But as coders become more powerful, they can do more, which makes them more valuable, if they or the businesses empluying them can invent work to do.

If all we can do is compete for the same fixed amount of work, though, it does look bleak.

Jeff_Brown··on AI Resistance: some recent anti-AI stuff that’s worth discussing
What an alien preference ordering.
Jeff_Brown··on Claude Opus 4.7
It might be a bad idea to put that in all caps, because in the training data, angry conversations are less productive. (I do the same thing, just in lowercase.)
Jeff_Brown··on The future of everything is lies, I guess: Where do we go from here?
As a consequentialist who shares the author's concerns, I feel fine (ethically) using AI without advancing it. Foregoing opportunities meaningful to yourself for deontological reasons when it won't have any impact on society is pointless.
Jeff_Brown··on Qwen3.6-35B-A3B: Agentic coding power, now open to all
This might sound snarky but in all earnestness, try talking to an AI about your experience using it.
Jeff_Brown··on Hungary Is a Laboratory for Illiberal Nationalism. The Results Are In
They're not saying the election results are in. They're saying Orban's style of rule has been a disaster for Hungary.
Jeff_Brown··on How and why to take a logarithm of an image [video]
I love 3B1B but generally don't have time to watch long videos. Can anyone sum up the punchline?
Jeff_Brown··on Turns out your coffee addiction may be doing your brain a favor
Yes, without a good experiment (maybe a natural one [1]) we can't know. Even if the study controls for everything observable, there may be unobserved differences that lead to the caffeination difference. For instance, even though two people might have the same job, education, etc. the one who is more ambitious, or creative, or hopeful, or simply healthy enough to feel like working more, might drink more coffee.

Jeff_Brown··on Bored of eating your own dogfood? Try smelling your own farts
Dogfoodung usefully connotes getting off your high horse, getting dirty, getting your face in it. I think it's perfect.
Jeff_Brown··on Polymarket gamblers threaten to kill me over Iran missile story
As someone who has received death threats, I can tell you, the comfort from the fact that they're usually not acted on, while real, is not huge.
Jeff_Brown··on Keybee: A Keyboard Designed for Smartphones
But does it have network access, or access to other apps (perhaps via shared storage)? There's no reason for it to have any of that, and there exist systems for tracking whether an app can do those things.
Jeff_Brown··on Keybee: A Keyboard Designed for Smartphones
When I go to enable it I get 'may be able to collect all the data you type, including ... passwords'.

'may be able to'? How is this not knowable? Do I have to wait for effect systems to gain popularity before installations make sense?

Jeff_Brown··on Attention Media ≠ Social Networks
This feels like the most important comment here. Do other Mastodon users feel the same? The OP Madden me want to try Mastodon.
Jeff_Brown··on How teaching molecules to think is revealing what a 'mind' is
You sound offended. Not my intent. It is linguistically difficult to avoid connotations of intelligence when describing artificial intelligence. What term instead of 'judgment' would you prefer for determining whether a user's request is ethical?
Jeff_Brown··on ShannonMax: A Library to Optimize Emacs Keybindings with Information Theory
Something I love about emacs is the ability to tab complete the name of a command. I do know a lot of keyboard shortcuts, but I use way, way more commands than I know the shortcut for. Need to rename a buffer? M-x ren-buf TAB should do it. Etc.
