> Your new focus is architecting the solution, not implementing every single step. So congratulations, you have been elevated to a manager of agents.

I'm not sure many engineers will welcome this "promotion".

spuz··on Why do AI models use so many em-dashes?
The whole interview goes into that and talks about the benefits and costs of allowing search and AI crawlers access to Medium articles.
spuz··on Why do AI models use so many em-dashes?
According to the CEO of Medium, the reason is because their founder, Ev Williams, was a fan of typography and asked that their software automatically convert two hyphens (--) into a single em-dash. Then since Medium was used as a source for high-quality writing, he believes AI picked up a preference for em-dashes based on this writing.

spuz··on Language models are injective and hence invertible
I think you are probably right but it's hard to find an example of a piece of text that an LLM is willing to output verbatim (i.e. not subject to copyright guardrails) but also hasn't been widely studied and summarised by humans. Regardless, I think you could probably find many such examples especially if you had control of the LLM training process.
spuz··on Language models are injective and hence invertible
Thanks - seems like I'm not the only one who jumped to the wrong conclusion.
spuz··on Language models are injective and hence invertible
Ah ok, for some reason that wasn't clear for me.
spuz··on Language models are injective and hence invertible
I remember hearing an argument once that said LLMs must be capable of learning abstract ideas because the size of their weight model (typically GBs) is so much smaller than the size of their training data (typically TBs or PBs). So either the models are throwing away most of the training data, they are compressing the data beyond the known limits, or they are abstracting the data into more efficient forms. That's why an LLM (I tested this on Grok) can give you a summary of chapter 18 of Mary Shelley's Frankenstein, but cannot reproduce a paragraph from the same text verbatim.

I am sure I am not understanding this paper correctly because it sounds like they are claiming that model weights can be used to produce the original input text representing an extraordinary level of text compression.

spuz··on Andrej Karpathy – It will take a decade to work through the issues with agents
Interestingly this is a question I've had for a while. Night brings potentially deadly cold, predators, a drastic limit in vision so why do we find the sunset and night sky beautiful. Why do we stop and watch the sun set - something that happens every day - rather than prepare for the food and warmth we need to survive the night?
spuz··on 4Chan Lawyer publishes Ofcom correspondence
I don't understand why the British government's solution is to impose orders on British ISPs as they have done with other websites that they want to block, rather than try to impose on a company based in another country.
spuz··on A competitor crippled a $23.5M bootcamp by becoming a Reddit moderator
What you are describing sounds like the behaviour of someone who is passionate, righteous and perhaps obsessed. That is not the case in the case of Michael Novati according to Lars Lofgren's post. He is claiming that Novati's Reddit posts are entirely driven by profit motives, not to do with the truth or passion for the code bootcamp space.
spuz··on How to create an OS from scratch
That simulated personal computer for a TV character actually sounds really cool. I love the idea that the environment would change from week to week with each new episode. What was the TV show?
spuz··on Why your outdoorsy friend suddenly has a gummy bear power bank
1 kilogram Calorie is the amount of energy needed to raise the temperature of one kilogram of water by 1 degree. 1 gram calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree.
spuz··on This map is not upside down
My Australian Geography teacher (in the UK) had an upside-down map and anti-clockwise clock on the wall and told us that was how all maps and clocks were in Australia. We might not have been convinced, but it certainly gave a different perspective on the way things are.
spuz··on Apple Photos app corrupts images
It would be very helpful to document the version number of the Photos app that demonstrates this behaviour so anyone else who is affected can use this article to keep track of potential fixes.

Interesting. Thanks.
spuz··on SkiftOS: A hobby OS built from scratch using C/C++ for ARM, x86, and RISC-V
What ideas do you employ around security? Do apps have full access to memory? To hardware? Is there a permissions system? Sorry I'm not that familiar with how microkernels work.
spuz··on Defense.gov Now Redirects to War.gov
Even if Trump does not respect the view of the courts, some of those working under him do. They can be held liable if they proceed to violate a court order. If they can be given a legal justification for the orders they are given, it makes it a easier to make them comply with the orders.

But even if those working under him are faultlessly loyal, that doesn't mean the rest of the population is. Trump knows that even his base won't tolerate behaviour that is blatently illegal (such as running for a 3rd term) unless there is some kind of legal justification such as an emergency war situation. This is what I believe this is all in aide of.

spuz··on Defense.gov Now Redirects to War.gov
You need to update your world model. Trump would very much like to officially declare war with Venezuela because it gives him certain wartime authorities (such as the Alien Enemies Act and the Insurrection Act) which he can use to to deport people without due process and deploy the armed forces domestically. This is why he ordered the destruction of a speedboat near Venezuela, has increased the bounty on the arrest of Venezuela's president Maduro and called him the head of the Cartel of the Suns. This is also why he is changing the department of defense to the department of war. He wants to use the pretense of war to subvert any checks against his power.

He likely does not want to actually invade anyone or do anything that brings actual war to the US but he does want the personal benefits that come with being at war.

spuz··on I accidentally became PureGym’s unofficial Apple Wallet developer
Authors use humour as a form of connection with their audience. It's a way of saying hey I'm a human and I have the same human experiences as you dear reader. Take the first paragraph for example:

> Wednesday, 11:15 AM. I'm at the PureGym entrance doing the universal gym app dance. Phone out, one bar of signal that immediately gives up because apparently the building is wrapped in aluminum foil

It says, "Hey I'm a human who goes to the gym and experiences the same frustrations as you do". Now imagine for a second this paragraph was written by AI. The AI has never been to the gym, the AI doesn't feel impatience trying to pass through the turnstile, the AI has never experienced the anxiety of a dodgy internet connection in a large commercial building. The purpose of any humour in this paragraph is completely undermined if you assume it was actually written by AI.

So please don't conflate being anti-LLM with being anti-humour. It's just the opposite. We want humour because we want to feel a connection with our fellow humans and for the same reason we should also want writing that comes from a human, not a machine.

I'd be interested to know which if any of the ID verification services were fooled by this.

Could you clarify what you mean by this?
spuz··on Quantitative AI progress needs accurate and transparent evaluation
Do you not think social and ethical issues can be approached rationally? To me it sounds like Tao is concerned about the cost of running AI powered solutions and I can quite easily see how the ethical and social costs fit under that umbrella along with monetary and environmental costs.
spuz··on GPT-5-reasoning alpha found in the wild
Not sure why you think that? One of their biggest sales pitches to businesses is the potential for their products to replace certain job roles in the future. Why wouldn't they be actively doing research on real-world usage and impact right now?
spuz··on Electric cars produce less brake dust pollution than combustion-engine cars
Yes indeed the London underground does use regenerative braking on many of their lines. The cool thing about a direct rail power system is that the voltage generated from trains that are braking can be fed back into the power rail to instantaneously power other trains on the same line that are accelerating. No need to carry the extra weight of a battery or flywheel. And like you say, it helps keep the tunnels cooler.
spuz··on Electric cars produce far less brake dust pollution than combustion-engine cars
Your source doesn't consider non-plug-in hybrids also known as HEVs because zapmap are a company that sell charging services. The number of HEVs in the UK is about twice the the number of PHEVs so the total number of hybrids is still higher than the total number of BEVs. In 2024, 6% of vehicles on the road were hybrid compared with 3.7% fully electric.

spuz··on “I noticed a clear violation of our contributing guidelines”
This would be best implemented inline with the textbox of the comment form. If you want to give people feedback on their grammar then do it while they are actually writing - not after. Otherwise you just make an already hard to follow thread even more noisy.
spuz··on Hyatt Hotels are using algorithmic Rest “smoking detectors”
And you will because "entrepreneurial" chains like Hyatt will lower their prices thanks to the additional revenue they get from this and other unexpected charges in order to attract more customers.
spuz··on LIGO detects most massive black hole merger to date
Assuming your 0.034% figure is correct, then one solar mass is equivalent to 2941 lifetimes of a sun's output, not 30. So 15 solar masses would be more like 44115 solar-lifetimes.
