What part of "8 years" did you skip ? It means that after that there won't be much ice left and the flow of water will go down.

Well, peak rate of extinction is not the same as "all the glaciers gone."

And, glaciers gone just means that the flow rate will equal the precipitation rate, rather than the precipitation rate delayed until the spring thaw.

Paypal was never prohibited from becoming a bank. They remained not-a-bank because they believed it was a more profitable arrangement. They have now apparently changed their mind, and in my view they're many years late in that decision. Other startup financial services companies have been nipping at their heels harder and faster in the last couple years. Recent politics and are mentioned in the same story but it can not be concluded that these are directly related.

Comment Re:Rejected the AMZN Aquisition? (Score 1) 96

That may explain it. I have a Qrevo S, which is from 2024, while yours is from 2022. The only thing that it ever gets stuck at is one spot where, from under the couch, it can see out the ground-level window, and get stuck between the couch and window ledge (not actually stuck, just confused), because the LiDAR sees out the window. And I fixed that just by setting a small exclusion zone there. It never "gets lost" - maybe your house has some vast open spaces that it can't handle? But the LiDAR seems to see pretty far. The only other issues I've had are things like where I'll have a loose cord on the floor or some large piece of debris or whatnot, and even then, it's usually good at not getting stock on them. I'm also impressed with how well it deals with doors vs. a Roomba - my Roomba used to always get itself locked in rooms by accidentally closing doors after it entered, while the Roborock really tries to avoid ever touching them.

The Qrevo S has actually rotating mops, and they do a superb job with the floor. Spotless. My robot has the hardest mopping job in the world, too - it has to clean under my parrot's cage, and he poops off the edge onto a plastic mat under it ;)

I've never had to contact support - hopefully I don't need to :)

Comment it's the complexity, stupid (Score 5, Insightful) 26

Speaking as an old graybeard UI guy.... we have just come up with more and more complex solutions to the same old internet "one weird trick" of putting your information on someone else's computer.

Yeah, I remember "Server Side Rendering"... we called Java Servlets or JSPs or PHP or ASP. There were clear divisions of labors and boundaries were respected.

Even when we had to go to make everything feel like an app, at least RESTful stuff still had those boundaries.

Now that everyone needs the same code running front and back, and JS (I'm not a hater of JS by any means but still) stuff like this is bound to have happened.

Comment "Nuclear device" (Score 0) 66

Look, I know "nuclear device" is correctly generic, so that RTGs and things like them, legitimately count. But let's be serious: right around the very same time this real stuff happened, some really great fake stuff happened too: the movie Goldfinger.

And once you've watched Goldfinger, "nuclear device" is just a euphemism for a bomb. So don't go calling RTGs "nuclear devices," please.

Comment Re:Robot vacuum cleaners - meh (Score 1) 96

A real vacuum cleaner just about maxes out a standard residential 120v 15a circuit, as anyone who remembers the incandescent bulb era can attest to. A circuit with a few lamps shared with a vacuum cleaner could easily end with you flipping a breaker or replacing a blown fuse.

When you look at the absolutely tiny lithium ion pack these robo-vacs come with, ...

Sitting on my kitchen table right now is a drone pack. It's 57,5Wh, smaller the batteries of most modern Roombas. It's 50C - thus it can output up to 2,9kW. And there's even higher packs available than that. Lithium ion cells can handle some truly high power outputs. It's *energy*, not *power*, that is their limitation. Run a pack at 50C and it'll be empty in a bit over a minute. That said, on hard floor surfaces there is absolutely no reason why you should be drawing more than 300-400W or so, and you can get by with well less than that. High powers are for like shag carpeting and the like. Also, the head matters more than the power (though of course contribute) - for a hard floor, for example, a fluffy roller head is ideal.
