The name is actually âoemolten saltâ and it is generally something more exotic like LiF-BeF2, LiF-NaF-KF or NaCl-MgCl2, not simple table salt (NaCl).

You can say "we replaced human computers with electronic computers". "Computer" used to be a job title.

If you think the Pope should refrain from offering moral advice because some people may not follow it, I think you may have misunderstood how the Catholic Church works.

Who wants to get up two hours before dawn in the winter? Not me! Who wants to get up two hours after dawn in the summer? Not me!

This is just like the people who stop taking their meds because they feel healthy. Get over it!

I really don't understand all the moaning and groaning about daylight saving time. People naturally wake up earlier in the summer and later in the winter, and DST is the most straightforward way to adapt our work schedule to that. We get 6 months of better sleep/work alignment in exchange for adjusting our sleep schedule by an hour twice a year. It's a big reward for not much effort, especially considering most of us adjust our sleep schedule ant the start and end of every weekend anyway, i.e., around 100 times a year.

I think the answer is no if you don't have clean access to the proprietary software, e.g., if you decompile or reverse engineer it in violation of a license agreement that you agreed to. That taints the spec, which taints the clean room reimplementation. I think this also applies to leaked software - if you know it's someone's trade secret, but you use it anyway to create a competing product, you can be sued.

But then if you want to plan meetings with people in other regions, you have to keep a table of "customary business hours" for every part of the world for every time of year. That ends up looking like a time zone / DST table, but without the standardization.

Theoretical and prophylactic are not the same thing. Quantum decryption is indeed still a future threat, but that doesn't mean you shouldn't protect yourself now. Various parties are already using a technique called "harvest now, decrypt later" to record web traffic today that they may be able to decrypt and read with quantum computers later. So using non-quantum-resistant encryption today is as risky as using plain text, just with a delay before the consequences appear.

I've ridden in one. It was just like riding in any car, but a little disconcerting to have the driver's seat empty while the car did its thing. Maybe a little smoother and more predictable than the average Uber.

Given how many Waymos there are on the road and how little trouble weâ(TM)ve heard about - despite breathless coverage of every incident, - Iâ(TM)d say they seem to be doing better than human drivers.

This is a fallacy. To halt climate change, we don't need to move away from extracting hyrdrocarbons, just from burning them. It would be a huge step forward to convert hydrocarbons to plastics using renewable electricity, then eventually recycle or bury those plastics. Using fossil hydrocarbons as a feedstock is potentially a zero-emission process, unlike using them as fuels.

I love the idea of e-fuels. But it would be cheaper to replace most of those cars with new EVs than to fill them with e-gasoline at $0.60 (extra) per mile, i.e., $600/mo. for the average car.

At the quoted costs, e-gasoline is about $1600/tCO2 avoided (say $15 extra per gallon of gasoline, which avoids 9 kg of CO2 emissions). Unfortunately, thatâ(TM)s around 8 times higher than the harm done by CO2, so even serious environmental economists would say itâ(TM)s not worth using unless costs can be brought way down.

As a starting point, consider using just the CO2 part of this system to sequester CO2 from aircraft. Or switch the grid to 95% renewable power and use the CO2 collector to sequester the remaining CO2 emissions.

Iâ(TM)m so tired of tech people coming up with new, unnecessary, overpriced solutions to renewable power variability or car range anxiety. Just stick in some batteries! This thing costs $15,000-$20,000, which means a $300/mo payment to get 30 gals of gasoline. Thatâ(TM)s $10/gal just for the equipment. Then theyâ(TM)re using 75 kWh of electricity per gallon, which costs around $30 retail or $10 from a home solar system. All to get you about 9 kWh of propulsion (after the 75% losses in the car engine). You could replace all of this for $1.35-$4.00/gal equivalent with an EV.

The summary says

This implies that in a rosier world, a majority of the companies would be optimistic about revenue growth. But raising revenue for most or all of the companies is not possible unless the customers (a.k.a. all the companies' employees) have more to spend, and no one is talking about raising wages as a result of AI. So where is all the extra revenue supposed to come from?

Time from bug creation to fix and time from bug discovery to fix are both important. But only one is easy to measure, and thatâ(TM)s what the authors measured. This blog post wasnâ(TM)t driven by âoewhat question is important to answer?â, it was driven by âoewhat can we say with these data?â.
