And a track day can cost just a few hundred bucks. It's not like you have to rent a whole track just for yourself.

Yep. I started looking into sports cars recently, and the general consensus among enthusiasts seems to be that for public roads, if you're not going to drive at reckless speeds then you'll have more fun driving a slow car fast than driving a fast car slow. Fun handling with modest horsepower is the way to go, you can have a great time without exceeding normal road speeds.

That is why people love miatas.

Why would that be your problem? Make it a warranty violation, and they can either get it fixed themselves, or pay you money you wouldn't have gotten otherwise.

Because people lie and still give you 1 star rating perhaps.

The same people, the ones prone to tinkering with their cars, might give you a one star rating for putting the car together with proprietary screws.

Don't get me wrong, i do not like it either but I do think often enough they do this for this kind of reasons and not to be dicks on purpose.

That seems unlikely since they can use the same factories and the raw material cost is significantly lower.

It's not panacea. Only lithium vs sodium is cheaper and they can use lower grade graphite which is just slightly cheaper (overall 30% reduction). Rest is same while it's a new manufacturing process. Meanwhile 99.99% production is focused and will be continued focused LFP.

That entirely depends on how large the market for stationary storage is going to be. On top of the price, sodium has advantage of being safer and usable in wider temperature range.

Who in their right mind would pay 40% more to pick a dangerous and fussy product just because it's a bit smaller and lighter for their home?


Sodium is obviously better option even for cars in very cold climates (which is somewhat of a niche (tho lfp cold gates even in mild climates)) and IMO CATL et al will charge premium for this while they can.

But initial claim was “fraction of the cost, tomorrow” which is super incorrect.


I did not say tomorrow. It will definitely take time.

What I'm opposing is flippantly relegating a new technology with real benfits, that the largest manufacturer of lithium batteries is significantly betting on, to the 0.01% of the market.

You say 0.01%, largest manufacturer of lithium batteries says 50%. If you meet half way it's still about 25% which is significant.

Oh god, of course it's mr undecided. Go thru years of his hype videos and decide if ANY of his predictions were right. Goes well with EV viking and "just (don't) have a think".

Yes, eventually it might be 50%, but right now you can't even get _specs_ from CATL while LFPs are traded like commodity.


I have no respect for what mr undecided is saying. I have respect for what CATL is saying.

Are you sure you aren't the one blinded by hype?


This a PR release. For example - where's volumetric density?

Intelligence is the ability to infer correctly from incomplete data.

I bought a Kobo for the same reason but when it came to buying books, none of the books I wanted to buy were on Kobo's store.


If you want to be part of Kindle Unlimited you have to give worldwide exclusivity to Kindle Unlimited, and can't have ever published your eBook on another platform.

Even if I wanted to join, Kindle Unlimited is not offered here. I can't even buy the eBook from Amazon.


My daughter wanted a book that was kindle exclusive in the US, and I found I could purchase an epub from another store by paying in euros and claiming to live in Europe. Needless to say I did this without a VPN and without leaving San Francisco. The book was still in English.

But I wonder if the reason for that little hoop was because of Kindle Unlimited.


It's not just that. E.g. Cooper and Hutchinson's edition of Plato's complete works, available on Kindle for $31.[1] Or on another tack, Yudkowski's recent If Anyone Builds It, Everyone Dies.[2] Neither book is on Unlimited, and I couldn't find either one on Kobo. I struck out half a dozen times in a row and finally gave up.

While it's true I don't see that version of Plato's complete works (in fact, I don't see any Hackett Publishing books), the book on AI[1] is available.

Oh weird, I'd just searched for it. I tried again with the US site and it came right up. Maybe their search isn't as good with typos or something.


Software verification has gotten some use for smart contracts. The code is fairly simple, it's certain to be attacked by sophisticated hackers who know the source, and the consequence of failure is theft of funds, possibly in large amounts. 100% test coverage is no guarantee that an attack can't be found.

People spend gobs of money on human security auditors who don't necessarily catch everything either, so verification easily fits in the budget. And once deployed, the code can't be changed.

Verification has also been used in embedded safety-critical code.


If the requirements you have to satisfy arise out of a fixed, deterministic contract (as opposed to a human being), I can see how that's possible in this case.

I think the root problem may be that most software has to adapt to a constantly changing reality. There aren't many businesses which can stay afloat without ever changing anything.


Maybe it's difficult for the average developer to write a formal specification, but the point of the article is that an AI can do it for them.


I think that's a really interesting idea.


You could also fill the context with just the book portion that you've read. That'd be a sure-fire way to fulfill Amazon's "spoiler-free" promise.


I agree but for some reason, there are people who enjoy doing that. I think they should be allowed to do as they like.

In any case, Amazon claims this feature is spoiler-free and that would be easy to implement. It likely works by feeding the book into an LLM context, and they could simply feed in the portion you've already read.
