aeonfox··on Donut Lab’s all-solid-state battery delivers 400 Wh/kg of energy density
> The motorcycle is real, you can buy it.

Pretty major point of difference though isn't it? They claim this will be out there in Q1 2026, giving a chance for sceptics and industry professionals to tear it down. If this is really the long con, they'd at least give a little time for the cheques to clear before their wild claims could be assessed?

The other possibility is that they have very little moat with this new battery tech, because it's so easy to manufacture. Being the first mover might be their only play, and it's only a matter of time before someone else figures it out (or it leaks).

> US seems outlier while rest of the world fatalities are decreasing

Europe can be explained by pedestrianisation of cities, congestion taxes, separated bike lanes that encourage bike use, vehicle safety standards that—at least until recent loopholes have emerged—have been keeping dangerous vehicles off the road. Even still, if you look at that graph you'll notice a little uptick in the last 5 years, curiously around the time that screens became more prevalent, but also...

> my guess pedestrians are disproportionately more at fault here - mostly impairment (meth, fentanyl),

A-pillar sizes and bonnet heights have all been increasing, reducing visibility of pedestrians. Sounds like a larger factor to me. People have been getting high and drunk behind the wheel for decades, but maybe it's more prevalent now?

> not by adjusting climate controls for 2-3 seconds.

That's really all it takes if a kid decides to chase after a ball on a side street. You might have seen them before they ran from one side past behind an occluding object and emerged on the other, with not enough time for automated systems to respond (if they respond). A lot can change in 2-3 seconds, and I'd be surprised to hear an experienced driver say otherwise.

I think I've said as much as I can.

aeonfox··on VW is bringing physical buttons back to the dashboard with the ID. Polo EV
> Except they are decreasing...

This data says otherwise. I'm certain pedestrian mortality has been increasing, and by the looks of this graph it looks like 'other road user' deaths are trending up too. If you have data to support your claim, keen to see it.

> Except HUD is kinda worse than center console

The glance time might be affected by a lack of contrast? Or perhaps the novelty of using a HUD? It's possibly right, but I'd want to see more study on the 'why' it's worse and whether that's a technical thing.

aeonfox··on VW is bringing physical buttons back to the dashboard with the ID. Polo EV
I was imagining a console that's at easy arms reach that's fixed into interior and don't require taking eyes of the road. The S3XY buttons look pretty cool, but they don't seem to be able to give you the resistive feel of something fastened to the interior. The Knob provides something like a console, but it seems pretty limited in how many tactile options it provides and you still need to take your eyes of the road. A number of simple dials with tactile clicks and fixed positions provide a user interface that don't require visual confirmation.

And touchscreens are another visual distraction. I think they're a contributor to the increasing vehicle accident and mortality rates. Ideally, nothing should take your mind/eyes off the road. A HUD for navigation and dashboard guages/alerts is about all anyone 'needs' in terms of display, but in the end it's about what individuals want, human lives be damned.

aeonfox··on VW is bringing physical buttons back to the dashboard with the ID. Polo EV
While we're dreaming, just have an interchangeable panel. Allow 3rd parties to make whatever dials etc. the customer wants. And if it were up to me I'd also get rid of the screen entirely and only have a HUD for navigation. It will never happen, let alone become mainstream, but dreaming is nice sometimes.
aeonfox··on Software Craftsmanship Is Dead
Or maybe software craftmanship was always dead (and still lives on). Good enough is sometimes perfect, and a good example of that was a HN post today about how the makers of CP/M looked after their customers, and made a beautiful compiler for a new language to build their version 2, but in the end they were beaten by a hacky clone of their software which was then bought by Microsoft, and then you know the rest.

https://news.ycombinator.com/item?id=46426614

But craftmanship lives on as market differentiation, which is how Apple became dominant. It also lives on in critical software where attention to detail is vital or extremely high-value (eg. Linux kernel, cryptography libraries, aerospace/automotive, medtech), basically anything where downtime or incorrect behaviour costs money or lives.

But in practice, wouldn't such an event on X large Chinese company have a cascade effect on stock values of all other Chinese companies?

No two ways to look at it. Electrification is the inevitable next step for mobility, and BYD are going to be top dog. It's pretty obvious why Tesla is 'diversifying'/divesting into robotics, but Asia has plenty of movers in that space too, not least BYD. SpaceX is the only moat Elon has left.
aeonfox··on Doom in Django: testing the limits of LiveView at 600.000 divs/segundo
The docs lead to a 403, but I'd be curious to know how it is simpler. I believe the Phoenix version uses Erlang iolists and immutability to make diffing more efficient, and perhaps the Django version has something similar?
aeonfox··on Doom in Django: testing the limits of LiveView at 600.000 divs/segundo
I assume Django LiveView is directly inspired by Phoenix LiveView. It's essentially diffing template expansion on the backend and sending patches to the frontend via websockets where JS then applies the patches. Clicks and other interactions are also transmitted to the backend where state for the socket is updated and the template is reevaluated, hence completing the loop.

> Technology is augmenting real world experiences all the time

As the sibling comment says, I never made a claim that technology writ large wasn't augmenting real world experiences. I did make reference to 'the technology', which if it helps to clarify could be read as 'a specific X technology'. A technology could be as broad as 'software', but it could mean a software innovation like 'infinite scroll with status updates'. How a technology is used can also factor in. iNaturalist, MeetUp, and hospitality club style websites are all social networks that encourage people to go out into the world and experience things. Even Facebook groups and marketplace can facilitate this to some degree, though real-world human connection is counter to its revenue strategy.

> and not always in positive ways.

Augmenting means to add to something, not take away. The word for that is detract.

> To get away from algorithms, away from being locked in and dependent on the platform, away from big tech chasing our attention, back to real connections as opposed to losing our followers with the Death of the Follower. We need open platforms such as Open Social Media and an open web

Nah. We need move back to the real world being the destination instead of the screen. If the technology is not augmenting your life in meatspace, it's slowly robbing you of your somatic experience and turning you into something more machine-like. Doesn't matter whether the technology is open web or proprietary, the effect is the same.

Most IP owners would pay the tiny fee just to hold onto IP rights and do absolutely nothing with it. If I were designing this hypothetical legislation I'd make it 10 years without a release that works on new hardware and the copyright is lost. This would at least incentivise the owners to do remasters just to hold onto the IP, something that would make them a few bucks anyway.

The middle and upper class, city people, are just a fraction of the population. If there's been progress, it's not bearing out in the data. Though there appears to be a slight inflection point around the 2010, it seems the trend is still up. Though this data isn't recent enough to include the effects of semaglutide.

aeonfox··on Accumulation by Dispossession
Somewhat related to this, I always wonder when I see people defending Apple (and to some degree Google) not allowing people to easily install software on their phones outside their app stores. The defence is usually that they provide some value-add, but then they take a more than ample cut from software developers—and even content creators via Patreon—to account for this purported value, without providing an easy/any alternative—if the benefits are so great, won't people keeping using the store? Prior to smartphones, if you owned the operating system, you truly owned it, and you could install whatever you wanted on it. It seems now that every time a new technology/updated product comes around, there seems to be a trend of finding ways to 'enshittify' it with ecosystem lock-ins, subscriptions, and gatekeeping for features and aftermarket parts that should be standard and interoperable. The normalisation of this kind of thing, and its defence by Joe Citizen, seems to be a kind of dispossession.

> That was a big part of the shift in 2008.

Your hypothesis might be right, but I've provided data, and you're providing opinions. I'm fine with being wrong in my claim, but I didn't earn the downvote when no-one seems to have a clearer hypothesis with better evidence. First, show me that this shift is peculiar to 2008. And then show me that this is what teenagers are killing themselves over.

It's not so much teenage credulity, or coddling parents. Teen suicide is the easily quantifiable tip of the iceberg when it comes to mental health outcomes. Conspicuously it started trended up after 2008, around the nascence of Facebook and smartphones:

I imagine it's not the waveform or current that matters so much, as the voltage. These motors would be powering massive blades encountering incredible resistance, so you need megavolts to move them, with an input voltage all the way down to near zero.

Imagine the MOSFETs on this thing! Do they have something that scales up to MV? That sounds like an engineering challenge in itself.

Full disclaimer: electronics is not my wheelhouse, though I have played around with motor controllers.

aeonfox··on Has the cost of building software dropped 90%?
I can't say my opinion has changed. It didn't give me results that more exciting or useful than Sonnet. Is it worth 3x price per token? I'm not so sure.

(It wasn't clear in my comment, but I already use agents for my code. I just think the OPs claims are overblown.)

I think you need to parse my comment a little more keenly ;)

This story isn't different to the usual "I made a throw-away thing with an LLM and it was super useful and it took me no time at all". It's very different to the OP stating you can throw this at mature or legacy codebases and reduce labour inputs by 90%. If the correctness of the code matters (which it will as the codebase grows), you still need to read the code, and that still takes human eyes.

aeonfox··on Has the cost of building software dropped 90%?
Just to test out the OP articles theory, I was about to write some unit tests. I decided to let Opus 4.5 have a go. It did a pretty good job, but I spent probably as much time parsing what it had done as I would have writing the code from scratch. I still needed to clean it up, and of course, unsurprisingly, it had made a few tests that only really exercised the mocking it had made. A kind of mistake I wouldn't be caught dead sending in for peer review.

I'm glad the OP feels fine just letting Opus do whatever it wants without a pause to look under the covers, and perhaps we all have to learn to stop worrying and love the LLM? But I think really, here and now, we're witness to just another hype article written by a professional blogger and speaker, who's highly motivated to write engagement bait like this.

aeonfox··on CATL expects oceanic electric ships in three years
I'd imagine it makes providing constant AC voltage to the engines pretty tough. It's even a problem for home energy storage because you need an inverter that can handle a very wide range of input voltages. Most inverters will cut off well before the Na-ion battery is full drained, vs a lithium which can go pretty much all the way to 0%.
aeonfox··on CATL expects oceanic electric ships in three years
Na-ion cells have roughly half the volumetric and gravimetric energy density of NMC, so it's double the weight and double the space. Apart from still being at least as—if not more—expensive as LFP, they also have a sloping voltage curve, vs lithium with is relatively flat, which poses problems for voltage conversion, and these engines are going to be taking kilovolts of power. So I think those problems would need to be solved first.
aeonfox··on Copper thieves are wreaking havoc across America
As a further point of contrast between the US and Oceania, the kind of copper theft happening in the OP are disabling communications systems:

> From January to June of this year, 9,770 incidents of intentional theft or sabotage on communications networks were reported, according to the Internet & Television Association, a trade group known as NCTA. That is nearly double the number reported in the prior six-month period. The attacks disrupted service for more than eight million customers.

> The cut lines have disrupted 911 emergency calls and internet and landline services, shut down at least one school and left whole city blocks in the dark.

... and to contrast, here in Australia, the mobile networks hadn't properly QAed their production deployment and access to emergency services causing an outage for 13-hours, likely causing people to die. The response was immediately establishing an inquiry and enacting new laws within 31 days of the incident.

In the past few years I've seen so many instances of day-light smash and grabs happening in the US in broad daylight filling my feeds. I've been waiting for the other shoe to drop – will that wave of criminality reach here? Certainly there's been an significant uptick of knife crime in Australia, people with mental health issues shooting cops and stabbing civilians, and the housing crisis is really causing problems around homelessness, but even still, Australia has nothing on the brazenness and scale of what is happening in the US. So when I say that third world problems are affecting the US, I refer to this broader situation.
