Comment Ignore what the customer asks for, we know better! (Score 1) 158

Amazon literally ignores your search terms - search "DDR5 32GB" and sort by price, and get two pages of DDR4 memory before anything actually relevant to the search. Set the sort order and have it constantly reset to "Featured" on every new search. I'm falling back to searching using DDG on "site:amazon.com" as that at least respects my searches. Newegg is only slightly better, alas.

It's the same enshitification that pervades other lines of businses like commercial air travel in the US. Customers are just another thing for them to squeeze and exploit as much as possible.

Comment Generalized coordinates (Score 1) 95

Can't be sure without access to the paper, but it sounds like their program has succeeded in finding some canonical coordinates for the underlying system. This is neither new physics nor a particularly new idea, having been introduced in the 1800s. Not to say that their program might not find some interesting / useful sets of coordinates, of course.

Comment 50 miles PHEV range is easy (Score 1) 123

My Honda Clarity gets mid-40s nominal in the CA SF Bay Area, often over 50 in warmer weather. It's ridiculous to claim that 50 miles EV range will be a challenge with 14 years of battery and powertrain development. Which said pure EVs will certainly win on almost all use cases by then, for the same reason.

Comment Charging isn't cheap for many people (Score 2) 159

In the SF Bay Area - a place with one of the greatest densities of EVs in the country - it is definitely not a given that they're cheap to charge. PG&Es tiered residential rate, into which most people will fall, is around $0.28/kWh - roughly the same cost/mile as a gas car with decent mileage. While it's possible to take advantage of their EV rate, it's not going to be a significant win for most people unless they drive well above average mileage/day, since it shoves daytime rates sky-high. Also, charging a pure BEV solely at night effectively requires installing a Level 2 charger and associated infrastructure, which can run into thousands of dollars depending on the circumstances.

Commercial charging is even more expensive. DC Fast Charge runs around $0.42/kWh, when you can find it. Not sure about Tesla Superchargers.

I own a PHEV and am considering a Bolt, but not because the cost/mile is low. It isn't, and won't be under PG&E's tender mercies.

Comment Re:Why are nutcases being given any credibility he (Score 1) 101

I once sat down on a plane next to a guy reading Einstein's Special Relativity book. He seemed like he might be slightly geeky and worth talking to, so I started a conversation. Big mistake; almost immediately he pulled out his 300 page manuscript about the luminferous ether and wanted me to review it and support his simple $250M satellite test program to verify it. Could not get him to shut up but at least it was only a two hour flight

Comment Why are nutcases being given any credibility here? (Score 3, Informative) 101

This has nothing to do with physics, this is just a fancier version of the cranks who sent letters to the Caltech physics department when I was an undergrad there, teasing their Wonderful Theory of Everything that Mainstream Physicsists were too stupid to comprehend.

Very on-brand for 2020, though. Call back when you've got some Phys. Rev. D papers published.

Comment This is a wild misreading of the blog post (Score 4, Informative) 337

The performance increase is due to algorithmic changes, not to Rust vs. C++. This is clear in the actual blog post, which mostly discusses the new filtering / tokenization algorithm. I suspect the Slashdot article is based on a superficial reading of the misleading ZDnet article about the blog post, not about what the Brave folks actually posted.

Buffett himself is doing quite well. But the ordinary people who agree with his views are not any wealthier than the ordinary people who invested in bitcoin.

The ordinary people who are Berkshire shareholders are doing just fine, thanks. I don't know if all of us "agree with his views" but most of us rather appreciate his investing and business performance.
