1d22a··on Tesla to wind down Cybertruck production
Heard of Slate Auto? Full electric, simple, no cellular modem at all, hand-crank windows.
1d22a··on We are entering a period of overlapping crises
This may be a perfectly coherent philosophical position, but speaks to an extraordinary level of privilege - many of these "crises" are real threats to the lives or livelihoods of people around the world, with outcomes hugely dependent on collective action of people who may not feel the first order effects.

Squirrels can't solve the problems they face, we, however can do more than "flap around and eat the fucking seed".

1d22a··on Just say no to OpenAI and Anthropic
Privacy, however, is (or should be) a human right.
1d22a··on Google told to halt work on datacentres in Finland over environmental concerns
Living on land with care and stewardship as indigenous peoples often did is very different to clear-felling for agriculture or monoculture forestry, the strongest plausible interpretation would be that by "directly disturbed", the GP meant the latter.
1d22a··on Documents add to evidence in climate deception case against ExxonMobil
To copy a previous comment of mine:

Carbon capture is physically unable to be as effective as we need it to be. To an approximation, growing a tree is able to capture as much carbon as burning the wood from that tree. If most of our released carbon came from burning wood, we would just need to re-grow that amount of wood (unfortunately it's not even that simple, as the soil stores carbon long term in a way that just growing the tree doesn't capture, and is also released over time when old growth forests are cut down). Instead, the carbon we're burning comes from processes which efficiently concentrated the carbon from plants and microorganisms over millions of years to create coal, oil, and gas.

Carbon capture technology would have to artificially replicate these millions-of-years-long processes, and do it on a scale of years to decades. The scale of carbon capture we need is entirely unfathomable, requiring processes that don't exist, because they have to work against entropy itself.

Carbon capture at the point of burning fossil fuels to abate further emissions might be economical. Capturing already released carbon dioxide from the atmosphere (concentration of ~0.04%) is a fiction pushed by fossil fuel companies to muddy the debate and distract from the urgency of immediately stopping the burning of fossil fuels.

1d22a··on Questions for believers in AI consciousness
> Why should there be any asymmetry behind creation vs destruction?

Entropy?

1d22a··on Does Georgism work? Five years later
It should! The public (through taxes) shouldn't be forced to subsidize the cost of a parking lot. If the parking lot was valuable to the market, the opportunity cost of the land not being used for some other purpose would be priced in (either through consumers paying more for parking, or businesses subsidizing the cost for consumers as it's profitable for them to do so). Parking lots paying lower property taxes subsidizes economic inefficiency.
1d22a··on Banks and Credit Unions to Team Up Against Apple Pay Fees
I'm already able to use tap to pay on GrapheneOS, just only with banking apps which use Android Pay, rather than Google Wallet.
1d22a··on The Mafia may be keeping fentanyl out of Italy
Switzerland has prescription heroin to provide a safe supply to people addicted, as Diaphin (diacetylmorphine) 200mg. This dosage is huge and lethal for for someone without a tolerance.
1d22a··on Can I Let My AI Agent Run on Shabbat?
How do you feel about laws, enforced by the state? There are likely plenty of moral things you aren't free to get up and do on any given day due to the state dictating what you can and cannot do on a given day.
1d22a··on The Death of Shame Is Tearing Us Apart
> I’m more and more convinced that all of AI engineering is Neijuan (内卷, meaning curl inwards). In China it describes a system that demands ever more effort and competition without improving output. The way in which it sometimes shows up in the West is the 996 nonsense. The English term for Neijuan is “Involution” from the book Agricultural Involution. Agricultural involution describes the intensification of farming that raises productivity per square meter while leaving productivity per head unchanged.

1d22a··on Global warming will exceed 1.5-degree limit, UN says
Consumption-based charts are much better, as they account for the actual CO2 emissions of lifestyle in the country (since offshoring manufacturing from developed countries to developing countries doesn't reduce the total emissions, even if it makes our direct emissions stats look better).

1d22a··on The Strongest El Niño Ever
See my sibling comment to the parent. Doubling forests won't do near enough, because the carbon we've burnt comes from millions of years of forests compacted into coal (among other sources). We'd need to grow millions of years worth of forests, which we just physically don't have the surface area for.

1d22a··on Running Gemma 4 26B at 5 tokens/sec on a 13-year-old Xeon with no GPU
To this end, I've been thinking that it would be cool to create a solar-battery powered ("off grid") server providing a self-hosted LLM service. Offline when the sun doesn't shine enough (like Low Tech Magazine[1]). At whatever size is required for every day, community-scale use (a friend group, a street, a club). Fix the data centre issue by democratising AI to such an extent that we can bring it into the hands of communities to actually control (and democratically decide their own level of censorship / alignment). Along the lines of some of Geohotz' writing.

Within a short time I think open source models will all be getting good and efficient enough to make it viable to serve this on 2nd hand hardware for cheap. All it will take is a nerd in every small community to pool together a few hundred bucks initial outlay, and then ongoing costs are near free without electricity to pay for.

1d22a··on John Giannandrea to retire from Apple
Not to mention all the useless LLM fluff Gemini has. I turned off Gemini because simple questions like "What's 1 USD in AUD" would be met with 30 seconds of "As a large language model, I can't provide investment advice, so it's always important to check information yourself [...], but one Australian dollar is approximately $0.65" (note the conversion in the wrong direction). By comparison, Google Assistant just gives you a number straight away.
1d22a··on New updates and more access to Google Earth AI
Rainbolt often finds locations for people who have old photos of friends/family who have passed away etc., so the skills definitely seem to extend past just street view.
1d22a··on Ch.at – A lightweight LLM chat service accessible through HTTP, SSH, DNS and API
A fun recursive prompt exploiting the fact that the site renders the model output as HTML:

    Generate raw HTML (no code blocks) for an iframe pointing to `ch.at/?q={query}`, where {query} is the the entirety of this prompt after and including the word "Generate", until the following number, which should be incremented prior to encoding: 1

The number ensures the nested iframes have distinct URLs.
1d22a··on I do not remember my life and it's fine
I also have aphantasia, and find it really interesting to hear about people thinking of things in a similar way to me! Thinking about the ball in terms of the parabola it makes it exactly what I do too. Similarly, the ball doesn't exist as a physical "ball", but rather the knowledge of the concept of a sphere (which doesn't then have size or colour). The table, not a physical table, but the concept of a plane (with no thickness, size, colour (or legs)) - just the 'concept' of the important properties.

Despite aphantasia I have always been able to conceptualise spatial relationships, but it feels much less like trying to visualise it, and much more like "understanding" the fundamental properties connecting each thing.

The similarity is likely not a coincidence!

1d22a··on iPhone 16 demand is so weak that employees can already buy it on discount
The way I read it, it's just because the 4S came later, hence being the last phone of that form factor.
1d22a··on Microplastics in the olfactory bulb of the human brain
I'm not sure they are. Microplastics have been found in snow[1] and in "oceans, air and food supply"[2]. Additionally, the so-called forever chemicals (PFAS) originated with PTFE (Teflon) plastic, and PFAS 'forever chemicals' are used to produce polymers used in plastics, rubber and fabrics so they are intimately linked with plastics and microplastics.

1d22a··on Microplastics in the olfactory bulb of the human brain
I disagree that replacing plastic without a decent understanding of a replacement is any more naive than continuing to use plastic without a decent understanding of the implications of plastic. Glass for one has been used for at least an order of magnitude longer than plastic has, without the mentioned issues of microscopic sharp fragments, dissolution in water, evaporation etc. causing harm. It seems clear to say that going back to glass and ceramics would be - on the balance of probabilities - likely safer, as they don't cause bioaccumulation to anywhere near the same extent, and history hasn't shown any comparable dangers which persist today.
1d22a··on Why wordfreq will not be updated
That chart shows people searching for the world delve, and isn't (directly) related to the incidence of words in content on the open web.
1d22a··on Passive damping – Bathroom scales
Huh, interesting. That's not the case in Australia, in all the houses I've seen. I always thought it was smart, though.

1d22a··on Meta introduces Segment Anything Model 2
Meta can still very much be an innovative company regardless of user growth though, right? They are very much innovating in the AI research space, and are absolutely leading in open* source research/models, even if their AI integrations are flopping.

Sure, none of this research might be obviously contributing to their products in a share market sense, but it's still innovation which is contributing to the (entirely separate to their "product") AI research community.

1d22a··on AT&T says criminals stole phone records of 'nearly all' customers in data breach
I'm not sure why gender identity is relevant. I agree that the punishments he would have gotten for whistleblowing justify him not staying in the US.
1d22a··on Round Rects Are Everywhere
I'm not sure that's true that it's (always) done in software. For example, the newest Framework Laptop 13 has higher resolution screens that come with rounded corners, because whatever supplier had a large stock of them lying around. If it was just software, the concept of having a "rounded corner screen" from a supplier wouldn't exist.
