It's a trade off: you get abundant free energy to run the server, with extreme constraints on cooling because your server is running in the most perfect Thermos bottle ever.

Others are taking the opposite tack: undersea data centers for abundant free cooling at the expense of having to get the power down to your servers.

If had to bet on which one is more practial, I'd go with undersea servers. Build them off the coast of Chile, run cables out from batery-backed solar plants in the Atacama desert.

microwave labotomy ... We just put the machine against your head here for a bit and those bad urges go away, all better.

Another poster mentioned that it's actually focussed ultrasound.

Still sounds like breaking a piece of a system by stirring the brain with a knife (lobotomy) or burning it out with heat (cauterization), electricity (electroshock) or mechanical shock (blow to the head) - just carefully focused without (substantial) damage to other parts of the brain or its casing.

Ultrasonic destruction of a piece of the brain's reward/punishment/desire/avoidance mechanism rather than persistent unwanted fat.

I think it may be evidence that Amazon has a shitty corporate culture that squeezes every penny it can out its employees.

Corruption can happen anywhere, but it's more likely to happen in totalitarian cultures where people feel like the system is rigged anyway. That's why countries like Russia and China have corruption problems. But I suspect the same feelings of me vs. the system occur in a capitalist enterprise like Amazon where employees are governed by dystopian, rigid, computerized metrics.

The restrictions are a mix of reasonable nuisance management and paranoia about who is flying drones, what they can do, and chain of custody.

Beijing proper is a city with a population density of over 21,000 / km^2 -- so you can imagine the chaos if any tech enthusiast resident could fly a drone without a permit. Except for a couple of free zones in the outer boroughs, New York City restricts drone launcing and landings within the city to flights with a permit and flight plan, because otherwise the sky would be black with drones. Many cities -- both red and blue -- have zone restrictions for drone flights, and those currently hosting World Cup matches have tightened them for the duration of the tournament.

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.
 

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

You have no idea how much better they can be if you haven't tried.

I, and many friends and coworkers, switched to Arc browser a couple years ago because tab management is such a gigantic pain and problem in most browsers. Arc fixed that for us (with spaces + vertical tabs). Vertical tabs are far easier to navigate and organize than previous approaches (tab groups, colors, multiple windows).

With Arc being deprecated in favor of AI browsing garbage, I am so thrilled and relieved Firefox and Chrome have decided to try to improve the worst UX of the browser.

One of the lessons we've had as the Federal, multi-branch nature of the US governmennt has frustrated Trump is that the government may be fucking us over, but it's not doing it in *unison*. It's doing it piecemiel, on the initiative of many interests working against each other, just as the framers intended. The motto on the Great Seal notwithstanding, there are myriad roadblocks to consolidating power in the hands of a single individual. It takes time and repeated failures. This is why the second Trump Adminsitration is worse than the first; they've figured out ways around things like Congressional power of the purse, put more of their henchmen in the judiciary, and normalized Congress lying down and letting the president walk all over them. It's a serious situation, although fortunately Trump isn't long for this world.

While that's true, a responsible generation aims to boost the next generation to a *higher* level than the education they received. The world has become more complex and faster-paced, and even if that weren't true, the consequenes of aiming high and falling short are better than the consequences of aiming for the status quo and falling short.

So while I'm 100% onboard with skepticism that technology will magically make education better, I think the argument that "the education I got worked for me should be good for them" isn't a strong argument. What we need is a better ecducation that would have been a better education fifty years ago: stronger math, science, and language skills, general knowledge, and, I think critical thinking and media literacy. Possibly emotional intelligence -- it's kind of pointless to teach people critcial thinking skills if they are carried away by emotions.

There are no economic or security reasons to blockade Cuba, so that leaves *political*.

It used to be believed that bullies were low status individuals who are lashing out out of frustration. But research has shown that bullying is an effective strategy for achieving and maintaining social status. In other words it's a political winner. So the focus of research has shifted from the bully to the people around him who enable the bullying. The inner circle are the henchmen -- people without the charisma and daring to initiate the bullying, but join in when the bully gets things started. Around them are the audience, the people who wouldn't risk participating but enjoy the bullying vicariously. And around them are the much larger group of bystanders, who don't approve but are waiting for someone else to stop the bullying. Then off to the side are the defenders, who stand up to the bully.

Perhaps the least appreciated supporting factor in the phenomenon of the high-status bully is the silence of the bystanders, which is dependent upon the perception of widespread approval. Since you can't visibly see the the line between the approving audience and the apalled bystanders, the silence of the bytstanders is absolutely essential in sustaining the bullying.

Lot's of Americans are apalled at the idea of using military force to inflict suffering on the Cuban people. But that's only politically advantageous *because* of *them*. Tney are indistinguishable from the relatively small number of people who are thrilled when Trump announced he can do anything he wants wtih Cuba. The gap between actual approval and *perceived* approval is absolutely critical in establishign and maintaining any kind of authoritarianism. This is why would be authoritarian leaders are so focused on punishing and marginalizing any kind of expression of disapproval.

In 1790, the US population was 94.9% rural. There is no country. in the world today that rural -- Burundi, which looks like blanks spot in the world at night satellite picturs, is 88% rural.

The largest city at the time was New York, with a population of 33,000. Northern Manhattan was near-wilderness, mid-town was farms and country houses.

In 1790 the US was. country you could "police" with sheriffs and volunteer posses, largely to keep the peace. If you got robbed, you hired a private thief catcher. This works in a 95% rural country with just 3.4 million inhabitants. It would be chaos in a country 87x larger.

8GB is plenty of RAM for what most users use their laptops for, if the OS doesn't gobble it up with background tasks. Probably be a good idea to steer clear of Chrome as a browser on these things.

It's actually more like an iPhone 16 Pro runing MacOS in a laptop form factor. Apple basically rummaged through their parts box and pulled out a mobile CPU that'll deliver 50% more single core performance than what's in a high-end Chromebook with only 80% of the power draw. And Apple's got *massive* economies of scale on those parts, so they can afford to deliver a lot of bang for the buck.

The only place the Neo appears to falls short is in RAM, but this is *not* a power user machine, it's for basic office tasks and multimedia consumption. Realistically 8GB is plenty for many users.

In any case, the desktop isn't the center of most users's universe anymore; the switchboard of their life is their smartphone. This is a gateway drug to MacOS IOS integration, and eventually onto the upgrade treadmill. Users will switch seamlewssly between their iPhones and Neos all day long, with data on iCloud and iMusic etc., and when it comes time to upgrade their phone or their laptop, they won't be *stuck* exactly, but if they leave the reservation they lose a lot. But they certainly could upgrade to a *much nicer* Macbook....

It's no wonder the other laptop makers are sitting up and taking notice. Apple has set up a one way conversion ratchet for people tempted by a really nice and perfectly adequate entry level machine at an entry level price.Nobody else has the vertical integration -- chip foundries to device manufacturing, to software platform -- spanning desktop and phones that's needed to do this.

And a douche bag of a president who drops bombs next to schools and kills 135 kids . Should resign on the spot for that.

Look up "human shields", the practice of siting military targets among (or in or under) large collections of non-military civilians, in order to deter strikes against them or produce propaganda claims of atrocities when they're attacked anyhow.

In such situations the fault for the "collateral damage" is assigned to the side that set up the arrangement, not the side that hit it.

Nevertheless, it should be noted that the US has been trying very hard to use precision munitions and extreme military intelligence to take out military targets with as little harm to the innocents they're embedded among as possible, with impressive success. Compare the amount of collateral damage in this war to any of those conducted in the 20th century.
