Nuclear is already about 20% of US electricity generation. I don't think many people are suggesting taking that offline. When people are talking about being all solar, wind and storage they are talking about _new_ generation. So the ev

Isn't there treble(3x) damages for knowingly selling something that violates others' IP? This seems like a risky gambit by Apple. I'm not sure what their endgame is, but having those potential damages stack up in the likely s

Yeah, it could be that they plan to do #3 through use of their chunky GPUs. There is definitely a lot of focus on the whole APU concept. From look at some of the dies and what projects like ggml have been able to do through mixed computatio

I've noticed that despite Apple's stated on-device aspirations, they've put very little incremental die space toward the neural engine in the most recent generations. I think there's a number of possible explanations for

Agreed, I think its much fairer to say they snatched a stalemate out of the jaws of defeat rather than just "this is good for Tesla".

PG&E commercial energy rates in California are $0.36/kwh including delivery[1]. Tesla charges about $0.50/kwh[2]. [1] https://www.pge.com/tariffs/electric.shtml [2] https://electrek.co/202

The price of charging is already dominated by the marginal cost of electricity, in the same way the price of filling your gas tank is by the price of gas. That will only be more true as charging gets faster. So an advantage in fixed costs i

People also made the argument that the exclusivity of the Tesla supercharger network was a positive for Tesla. It's hard for both to be true. I think the reality is that uncertainty about charging away from home pushed a lot of people

Unfortunately not everyone we dislike is bad. I think this is a case of the fundamental attribution error: Most mean people aren't inherently mean, but are in circumstances that have made them so. Yes, there are newgrad "rockstars

They aren't manual takeovers, Kyle already responded[1] to this himself and clarified that they are requests for input which themselves mostly autoresolve. This is closer to an active learning loop than humans taking over. [1] https:&

I just do not understand how people can look at a company that has achieved what Cruise has with such pessimism. Successfully completing 250k autonomous rides is an extraordinarily achievement. Yes, there have been problems, but the issues

1) There is no reason to attribute all of the carbon intensity to the last use to be added. It is far more accurate to estimate the carbon intensity of something by the blended production mix at its time of use. Fossil fuel plants are often

Mackay's book, and this discussion, are in the context of a hypothetical future where Britain is powered predominantly by solar and wind. It's not even that hypothetical anymore, because as you can see from this dashboard( https:&

I'm sure he was. It's easy for us to see 15 years later that the combination of EVs + solar/wind has a huge efficiency gain because you can get to avoid internal combustion altogether, but EVs were nascent enough in 2008 for

I love this kind of hypothetical analysis, but I'd also like to point out there are already people making real strides towards this on an individual level in the UK. Youtube channels like ElectricVehicleMan catalog what a conscientious

Correct, a lot of Mackay's estimates fail to account for the difference in delivered efficiency between electric solutions and their gas counterparts. For instance in his car section[1], he estimate you'd need to produce 40kwh to

Deliveries of any reasonable size reduce vehicle miles travelled for goods. If a delivery driver can do 50 deliveries in a 10 mile route, that is much, much better than each one of those people driving to the store and back. I live in Brook

Agreed Amazon isnt the most reliable, but as I said, I corroborated this at a few other stores. Costco generally has fixed markups for its products (15%), as does Trader Joes. The fact that you haven't seen price fluctuations there ali

I have been fascinated by the price of oats recently. The 8lb box of oats I have been buying from Amazon for several years suddenly went from $15 to $32 in July. Paying $4/lb for grain feels excessive given that meat is cheaper than th

That makes sense, I'd still like to know what kind of footprint the combined decoder needs.

Negotiation is not an effective strategy when there is active collusion to fix prices. You are commenting on a story where a jury just found that had been systematically done.

I agree that is how I'd expect it to be implemented, but I'm not sure how small it would be given the processing bandwidth we are talking about for 4k video. I'm guessing this is a distinct region of the chip and not integrat

How much silicon does it take to add an AV1 decoder to a chip? The areas Apple highlighted in their A17 release looked pretty substantial, but I wasnt sure if it was to scale. https://b3148424.smushcdn.com/3148424/wp-co

Hawaii is the only state that produces a significant fraction of its electricity from oil. Something like 40% of continental US electricity is already low-carbon(nuclear, wind, solar) and the bulk of the rest is natural gas, which produces
