IsTom··on Claude in Chrome
Well, instead of one agent (the user) to phish there's two (both the user and the browser agent) and you only need to convince one.
IsTom··on I've been writing ring buffers wrong all these years (2016)
Probably there are less people excited to make another CRUD app than to write embedded code.
IsTom··on Great ideas in theoretical computer science
There were surprising results in computational complexity before. We can't prove that P /= PSPACE which should be much easier to prove and yet people are stuck on trying to prove P /= NP. Personally I don't think that P = NP and if it were it would be very surprising, but "very surprising" in not "out of the question".
IsTom··on Researchers seeking better measures of cognitive fatigue
I feel there is more than one type of mental fatigue. Some of them can be forced through (e.g. the emotional kind that happens when you have to do something you don't want to do) and some can't (e.g. not having enough sleep for prolonged time).

> It works via model building and next token prediction, which is not interpolative.

I'm not particularly well-versed in LLMs, but isn't there a step in there somewhere (latent space?) where you effectively interpolate in some high-dimensional space?

IsTom··on The US polluters that are rewriting the EU's human rights and climate law
That kind of sounds like they should be put in jail to stop this.
IsTom··on All the Way Down
> Try talking about biological operations without invoking “function”.

If you had a strong vendetta against mistaking map for territory, you could very well talk in terms of past survival and statistics. It's just not necessary for regular biological talk. It becomes relevant only when you start going to the boundaries.

> Why does striking a match against a matchbox consistently produce fire?

Because you wouldn't call these objects a "match" and a "matchbox" otherwise.

> What's the motivation or goal? And why that goal is pursued? What is the force behind seeking of that goal?

There's no force and there's no goal. These things happen because every moment is a direct consequence of the previous one.

IsTom··on What, if anything, is universal to music cognition? (2024)
Before 7th harmonic all you have is octaves, fifths and major thirds. If you want to stick to making other pitches out of stacked fifths and major thirds you'll end up with other compromises.

7/4 ratio should be simple, but it'll sound out of tune (over 30 cents) in a normal context. Many BP intervals are just as simple and they'll sound very out of tune to people unused to them.

Seventh and eleventh harmonics are way off. If ratios were the fundamental thing Bohlen–Pierce would be about as pleasant as 12TET to people.

> allowing multiple keys to be played without retuning the instrument

That's another simplification, real pianos are not tuned to 12TET, but use stretch tuning (which can be over 30cents off in the lower range).

I'd rather argue that people like what they're used to and so "people like pure ratios" is seemingly only true if "pure ratios" are not really pure. And that's ignoring a lot of the music that doesn't have roots in Europe.

Typical person on the internet will be really used to 12 tone equal temperament, for just tuning most intervals are 10+ cents off even if you allow pretty large ratios: https://en.wikipedia.org/wiki/12_equal_temperament#/media/Fi...

Many just intonation chords (where ratios are actually integers, not approximations of them) will sound out of tune to most people.

> Humans everywhere seem wired to favour simple integer-ratio rhythms

That's what people write in the sheet music, but reality is more complicated than that. Notably in swung rhythms ratios are blurry (and dependent on BPM) and specific performers in band will play different ratios at the same time (e.g. drummer will play straighter, soloist will swing more).

I think OP means that it has come a long way from the simple mental model of µops being a direct execution of operations and with all the register renamings and so on
IsTom··on Why is there so little GenAI content if I use the small web filter?
I'd hypothesise that people doing small web kind of blogs just don't find GenAI interesting. They're doing things instead of trying to make LLMs do things.
IsTom··on Physicists drive antihydrogen breakthrough at CERN
If you can create enough AM to last a space voyage you certainly know how to build big enough particle accelerators.
IsTom··on Physicists drive antihydrogen breakthrough at CERN
That's the point, evaporation turns matter into energy. You can tune power by chosing mass of the black hole and then feed it regular matter at a steady rate.
IsTom··on Physicists drive antihydrogen breakthrough at CERN
If you can electromagnetically trap enough antimatter to use it as fuel you could as well trap a miniature charged black hole that can be fed regular matter to produce power, which skips the whole inefficient part of making antimatter.

That's a pretty cool paper, though it does get more elaborate as you're saying. In 20/20 hindsight lipschitz bounds do make sense.

I wonder if it would help if you looked at gradient of the SDF as well – maybe you could walk further safely if you're not moving in the same direction as the gradient?

One thing with chat control I don't get is why can't it be vetoed by a single member? That doesn't seem like part of regular trade policy competency of the EU
