Yes, and almost the entire mass of the continents was aggregated in Gondwana which included the South pole. Almost nothing was in the Northern hemisphere, so there was one big cooler very mountainous continent to the South and one giant warm ocean to the North and everything about the weather and wind patterns was different. Throwing out one fact without all the rest of the context isn't useful. It was a very different planet at that time, and the temperate zone was likely inside the Antarctic circle. So, while peak CO2 may have produced mean Earth temperatures as high as 36C (11C higher than today), the position of Gondwana greatly mitigated the impacts of these temperatures on life at that time.

Beautifully put together video on the Panthalassa site, but the facts buried in it belie key assertions. They have created a gigantic expensive machine to accomplish what a $1000 diesel generator can provide. They are orders of magnitude off in their costs per kilowatt from being the least expensive energy source they purport they will be and I do not see how they are going to close that gap with scaled manufacturing. Giant devices that can survive in the ocean are expensive. They are building a 3D device that effectively makes energy from a 2D moving surface. They are going to quickly hit a size scaling limit where the bigger they go the less their efficiency in device cost versus energy available is going to be. If the current 12m circumference, 46 sqm device gives kilowatts, they are going to need 46,000 sqm device to get megawatts ... that is something three times the size of the Nimitz. They cannot scale up in size to gain a cost savings and they cannot make a bunch of small devices like their current prototype to generate enough power to make it work it. I do not see a cost-effective happy middle between these extremes. Love the engineering just do not see this ever being cost effective.

This isn't Reddit, and your post is off topic. Should the government do this? Maybe. Should it be an international committee of governments? Probably.

Kid in my hometown just got run over by a train on an e-bike, so bad stuff is happening.

Years ago, I tried to get licensed for a Honda motor scooter, which required doing that figure eight. But the Honda had this enormous square fairing on the front wheel that made it impossible for you to actually see the front wheel, so you couldn't actually tell if it was in the figure eight - you couldn't see the figure eight, you had to guess where it was at in relation to the tire. It was also not very stable, so at slow speeds it tended to fall over. So I failed the test. Twice.
I asked the instructor(who stood by carefully watching as I farcically attempted the figure 8) If I could remove the fairing just for the test. No.
So I simply used my learners permit and didn't ride it at night.

You sound edgy. Perhaps you should have "amerikkka" stenciled on your hoodie? You'll certainly impress everyone with it.

No mystery why Slashdot's active users are in the three figures.

If I operate a motorized vehicle on the street I need a license, insurance, registration and a street-legal vehicle. It's already against the law for an unlicensed little shit with no lights, safety equipment or common sense to suddenly dart out into traffic, swerve through screeching tires and near-misses and then do a wiseass pop back on to the sidewalk at 20-30 MPH. It's against the law to ride a motorized vehicle on the sidewalk too.

Oh, and shout out to the Mensa members who do the same thing wearing dark clothing at night at busy intersections. Every one of those goddamn bikes comes with lights installed. Except yours. Right bro?

Get a license and insurance or get the fuck off the road.

In many cases students need to not only know something but be fast at getting to the answer in order to progress in their studies. This is especially true with math and science. It is not enough to have a generally correct idea of how algebra works when taking calculus, to succeed at calculus you have to be fast at algebra. You get fast by doing boring homework ... over and over.

My son got an A in high school calculus, but I was suspicious because I never saw the homework coming home. College calculus was a harsh lesson to him that he had not actually learned calculus in high school.

My son was not alone in his experience. This was already happening to 3 in 10 kids a few years ago: https://www.utdanacenter.org/b....

Less homework is just going to make this worse.

So change tax law and not vote in a "we'll randomly take five percent of your stuff". It really is that simple.
Want a way to start? Give everyone skin in the game with a flat tax. no deductions, and i don't care if you're living off a paycheck or some elaborate loan scheme: it's your income, and you pay tax on it. If you want to fund services for the poor, make it completely separate from the tax code.
Because it's real easy to vote to tax everyone when you're not paying any taxes ( the poor) and it's real easy to game a complicated tax system when you have an army of employees to do this ( the rich).

Even this "I'm the LA TIMES and I never met a tax I didn't like" article cites it. : https://www.latimes.com/entertainment-arts/story/2026-01-10/california-made-them-rich-now-billionaires-flee-when-state-asks-for-little-something-back

I read the bill myself to find the exact clause because people have been saying this and I wanted to verify. , You're correct. Essentially, it says California's congress can modify the bill once it's passed with a 2/3 majority. So if they want to lower the threshold, or make it annual, they can vote to do this without putting it up to the state voters. As long as it fits within the intent of the original bill. And as the original bills intent was to finance healthcare, that's a pretty lower hurdle.

And getting a 2/3 majority in California for raising taxes is like getting throwing fish food into a koi pond and wondering how many fish will eat it.

Not only is an easy change to more than once already built into the bill- it can be done without a vote - they've also built in the means to expand it past billionaires.
"50310. Legislative Authority. The Legislature may amend the 2026 Billionaire Tax Act, by statute passed in each house of the Legislature by rollcall vote entered in the journal, two-thirds of the membership concurring, if the statute is consistent with and furthers the purposes of the 2026 Billionaire Tax Act"

Feel like applying to those who make 100K?Feel like making it an annual fee? Just needs a 2/3 vote. And in California, that's pretty easy to come by.

The price for a working system was high, but AT&T sold systems with just Unix running on them for much less. If I remember correctly every little component was a plus-up (sh, compiler, nroff, etc). The sum of all of the plus-ups to make a useful system was high. But you could buy a system that booted but couldn't do anything for much less and some people did which did not make for happy customers. We got two for our university lab on a 2-for-1 deal on the hardware and a free-to-us university-wide software license. Wasn't a bad deal for us, there were only 3 vendors selling 386 based systems at the time and AT&T was one of them. One of those clunky hard drives did not even last a year and its 3C501 based networking stack was awful.

And you're too goddamn stupid to realize you're freezing to death. Maybe they'll ping your phone and find you in a frozen doomscrolling pose under 17 feet of snow. Public education is really lighting up that scoreboard!
