Comment Exodus (Score 2) 15

It might be too soon but the Exodus Technologies third-order Coulomb devices (IIRC) are built for this kind of very low impulse long duration lifiting.

Getting a rig up there to clamp on to the Hubble is probably the hard part of the project.

High-impulse propulsion is more likely to damage it than low and slow.

This was during the "NJ Drone Flap".

Trump was on TV saying he'd been briefed on them and the drones were "tracked back to their garage".

Last thing he said about it before his FAA said "they were authorized, we're not explaining, stop asking".

Matthew Livelsberger said they were of Chinese origin.

Robert Hastings wrote an entire book on unidentified craft over nuclear facilities covering four decades of documented incursions.

The FoIA request sounds like good data but nothing new.

Comment Turbines are efficient, simple and noise-optional (Score 1) 44

They're not popular by accident. How quiet they are is up to the humans who spec their enclosures. (Ditto with large diesels which are routinely made sufficiently quiet for cruise liners.)

Industrial flue gases were traditionally exhausted by tall stacks whose draught pulled fresh air into the furnace at the base. A more recent reason that's done is to reduce ground-level pollution.

Turbines need not be run open like an engine on an outdoor test stand. That's why Air Force bases have sound suppressors to test engines in and out of airframes. Those "Hush houses" could be much quieter but are mostly located on operating air bases where other, installed engines running in afterburner for takeoff are normal.

From what I can tell most middle managers hate their employees - especially those who are smarter and more skilled - and can't wait to replace them.

They all probably think they'll be one of the last humans at the company.

It'll be funny when AI supplants middle management.

The right way is for a manager to be the advocate and ally of his subordinates. It can work really well but there's little place for ego and envy.

It's just used an excuse for censorship is the main problem.

Abuse is inherent in the system as currently defined.

They could use some proxy like view counts, but that would be objective, not subjective.

Yet every once in a while I look up some obscure biological molecule or plant that hardly anybody cares about, mostly for the external references because the articles are so short, and I'd hate to see those get purged. I've found some odd and rare flora growing in my forest and appreciate the information.

Don't trust old phones with too much value.

There are hardware bugs on Bluetooth, WiFi, and SS7 that are fairly easy to hack with the right setup and SS7 especially is built into the same baseband controller so main memory can be exfiltrated over cellular even without an active SIM.

Keeping it turned off most of the time reduces the attack surface, of course.

A few phones do better - switchable modems, etc. but very few and even some phones that meet GrapheneOS specs are imperfect.

An old ThinkPad with LibreBoot is probably OK if you want to get really nerdy. Yet 0.00001% of the population can handle that.

Hot/warm/cold is of course another layer of protection. But again, very few people can manage this.

Still, if you are transferring $200 to your dedicated phone to go out shopping, it's not very tragic if it gets lost.

We really don't have a good solution for the 99% yet. So companies like Binance step in and make a profit (as long as they can assume liability and responsibility for losses).

It sounds like that devops laptop had /way/ too much access. Where's their multisig for billions of dollars? I would never have guessed Binance would be one so lax. Doing it right is way cheaper than a shareholder lawsuit.

It seems more likely that what they're looking at is 'nobody' who reads Reddit posts without logging in will ever need to visit Reddit.com because they can just get all the answers they want from a Gemini query.

I can see their conundrum while noticing that it will suck for humans more than AI and that AI - as currently [not] enforced by law - is the primary culprit in this round of enshittification.

The current economic situation is that all profit from the current web will accrue to the Mag7 while their datasources will foot the bill for making it possible.

If somebody doesn't invent a better economic model soon there won't be much content left for AI to scrape and injest.

Proton used to let you buy an account with Bitcoin. Then they started requiring a credit card number or an outside email/phone.

It was clear to me that the perception of security replaced privacy.

I'm not sure what I need Proton for that needs my banking information tied to it.

The article is actually reassuring that I didn't misperceive what was going on.

I once calculated how much it would take for the USA to offset its emissions. It would need to double logging operations but sequester (bury) half of what was logged in a way that itself generated no new CO2 emissions. The amount of land required assuming 30 year trees being logged is about 16% of the total area or about 20% of the lower 48 states. That's roughly a 50% increase on current forested land. Or alternatively, about 1/3 of current farmland would need to be converted to forest. That last statistic is probably only possible if everyone went vegetarian, but there are probably many bits of non-agricultural land that could be used. Actually sequestering that much timber would be hard to achieve. Granted, making everyone have their laptops made from birch and wear clogs would use a bit, it would still be an issue.

Comment Re:New Nuclear Please (Score 1) 95

Nuclear: ~5–12 g COe/kWh

Wind (Onshore): ~11–26 g COe/kWh

Solar PV: ~85 g COe/kWh (mean)

Natural Gas: ~486–499 g COe/kWh

Coal: ~888–1,001 g COe/kWh

That looks like nuclear is the way to go but the issues are the time lag and availability of fuel and cost. If it takes 25 years to get a nuclear plant up and running and it lasts for ~60 (some last longer, but many don't) then assuming coal is the fill in, then the average over that period is (1/85)*(25x900+60x13) = 273. Solar is trickier to calculate as it would need a replacement halfway through that period but that's likely to be more efficient and have a lower CO2 footprint so I am assuming that this cancels out, roughly, then it's (1/85)*(5x900+80x85) = 132. If you assume 10 years to build it's 180g. Even with mid-life replacements, it's still lower over 85 years than nuclear. Overall, though, it's about a system so there might be storage involved, etc. and always-on power has an economic and social benefit. Onshore wind will do better as g/CO2 are only a bit above nuclear, but offshore is between onshore wind and solar

We don't have to do either/or - we can replace with both in parallel. How much depends somewhat on cost and finance as well as other factors.

The arithmetic is different if you are replacing natural gas. Someone else can calculate that.

France has a low level of CO2 per kWh but achieved it through massive amounts of government spending and central control and the price to the consumer is subsidised. And even now, Germany is still coping with reunification effects. But what was possible for a particular price from 1970-85 (the period of expansion of French nuclear) isn't necessarily so easy now as the costs for construction have increased and that level of state control and investment in a Western nation is unlikely. Look at the UK - 12 sites permitted but only two being built and well behind schedule and overcost, or new French reactors - ditto.
