"...putting a satellite dubbed Vigil into orbit around the Sun, positioned roughly the same distance from the Earth as the Earth is from the Sun. "

Ummm. If it were in line with the Sun, then it would be 'on the Sun'. If it were laterally positioned, then I suppose it could be anywhere...

Comment Check my math (Score 3, Insightful) 84

The article begins,

"Humans produce around 4.4 billion tons of concrete every year. That process consumes around 8 billion tons of sand ..."

Are we to assume that somehow billions of tons of sand are 'consumed' during the process, never to reappear?

And I agree with the other poster: while this might make an interesting doctoral thesis, I can't see how collecting coffee grounds on that kind of scale could consume less energy than using sand.

"...and force everybody to use wireless"

A lot of telcos want to get rid of copper and replace it with fiber optic cables. The bandwidth capacity of fiber far exceeds copper or wireless, and almost all services available on copper can be reproduced on fiber. Wireless or cellular hubs are ultimately served/connected by fiber, so fiber is the core of communications networks going forward.

Comment Where does the heat go? (Score 1) 138

This might be a silly question, but...

The same amount of heat is still initially generated, the liquid just does a better (faster) job of pulling the heat away from the computers. But the heat is still there, contained within the liquid. You still need to remove the heat from the liquid, so where does it go and what is the mechanism to draw it out?

"The clear fluid looks just like water, flowing gently through the tank that holds the servers, pumped up from underneath and then spilling over the top like an infinity pool for cooling before cycling back through the tank."

OK, but how is the heat extracted from that pool? Don't we end up going back to air or water-evaporative cooling to cool the cooling liquid?

Comment Turn the tables (Score 2) 37

Is there a reason why, if we're so far behind, we can't just turn the tables (on the usual US/China relationship) and 'borrow' their IP and use it in the US?

(I am NOT advocating copying word-for-word, but rather using their work as a source of ideas for our own regulation. Kinda like feeding their information into our ChatGPT...)

Comment 1984? (Score 4, Interesting) 244

Wasn't there a book about a time when 'facts' would be released to the public, only to be changed the next day to suit the whim of those in power? To reflect a pseudo-reality that aligned with the prevalent belief system pushed by a few?

What was the name of that book again? It's on the tip of my tongue...

Comment Teach it in high school (Score 4, Insightful) 425

I fear that most people reach adulthood without anyone ever having The Talk with them. No, not about that. About their long-term financial health.

It need not be a long class that lasts a year, but I get the impression that little, if any, class time is spent showing students the benefits of taking steps to safeguard their retirement before they reach 65.

And that's not just 'putting a little aside'. All the choices you make in life contribute to where you stand once you hit 65 (or 70, or whatever). Did you splurge on a boat, or a sports car, or lots of vacations? Or, to be frank, a large family?

Financial health is not a partisan issue - it can affect everyone. (speaking as someone who really didn't start planning until my 50s)

Comment Re:Why is caller ID spoofing possible? (Score 1) 38

To the best of my knowledge, the following only applies to ISDN PRI and CAS trunks;

All carriers can apply 'Call Screening' to a set of TDM trunks. Call Screening just means that the carrier allows the outbound calls to send whatever CID number the PBX outpulses *as long as that number is found in a pre-determined list of numbers that the customer was assigned when the service was turned up*. If the number is not on the list, I believe they just substitute the BTN (Billing Telephone Number). Some carriers always have CS turned on, some do not.

I wonder if you could implement that for VoIP. The carrier would have to inspect all outbound packets (looking for VoIP/SIP packets). Maybe too many people would complain about Big Brother tactics.
