Comment Re:Pluto is a planet (Score 1) 59

Thank god for that. It was hard enough to learn 9 (now 8) planets at school. Can you imagine having to learn all the names if the hydrostatic equilibrium definition held?

Since when does science work by a standard of "what is easy for children to memorize lists of"? Do we say "There are 8 rivers in the world, and all others are dwarf rivers, which really aren't rivers" to make it easier on kids? Do we say "There are 8 bones in the human body, and all others are dwarf bones, which don't really count as bones"?

That's not how science works. Science is focused on practical distinctions about how things developed and their physical properties relative to each other. Hydrostatic equilibrium is a very practical definition. The process of undergoing relaxation induces metamorphism and releases heat, altering bodies. You go to non-equilibrium bodies if you want to study the primordial makeup of our solar system. You go to equilibrium bodies if you want to study tectonics, volcanism, non-primordial chemistry, and search for past or present life. The boundary could not be more meaningful. Yes, there is a bit of fuzz between equilibrium and non-equilibrium, but the same applies to pretty much all scientific fields.

It probably does cost Google something. They scan apps and devices for malware, and anything that increases the number of apps and ways to distribute them will increase the cost. They also have to certify these app stores, they aren't just going to let anyone set one up and start distributing malware or pirate streaming apps.

It feels calibrated to deter unserious applicants, but not cause further legal woes.

The real issue is F-Droid and similar open source app stores. It remains to be seen exactly how it is going to pan out.

Supporters of the IAU definition (which I should add was a deeply biased sample, in that it looked like they were headed toward no definition or a hydrostatic equilibrium definition, so most supporters of that left, but the people trying to switch it to an orbit-clearing definition stayed) will argue that it's cleared if the remaining objects are trivial transients or in orbital resonance. But that's not what the IAU definition says. Also they'll point to the Stern-Levison parameter, but (A) that was based on the ability to scatter today's distribution of asteroids, not the primordial distribution, which included outright planetissimals**; and (B) Mars didn't even clear it's own orbit, Jupiter did. Also, in the paper that introduced the Stern-Levison parameter, they argued for a better definition where you combine adjectives and nouns (each with specific implications about the body) as needed to describe its size, composition, etc.

But the OP's point stands, in that it's stupid to say that something is a "dwarf planet", yet not a planet. It's like saying dwarf stars aren't stars or dwarf galaxies aren't galaxies or whatnot. An adjective-noun is almost always a noun, that's how language works. In the cases where an adjective-noun isn't a noun - say, "shooting star" or "slow worm" or whatnot - we treat these as scientifically erroneous colloquialisms, and formalize corrected scientific terminology. We don't do literally the opposite and have science codify misleading language.

Speak for yourself, Pluto is fascinating. Tectonically active. Cryovolcanism so abundant it appears to have formed large mountains by the merger of individual domes. A gigantic scar exposing its mantle, which over time roils in massive convection cells, pockmarked in sublimation pits. Mountains drifting like icebergs and accumulating on the shore. Penetentes (sublimation ice spikes), the size of large hills. A multilayer blue atmosphere, in which organic chemistry occurs, depositing not just organic matter onto its own surface, but that of its moon as well. Active glaciation. A probable subsurface ocean, in contact with rock. Conditions suggesting it was habitable when it formed.

IMHO, it's way more interesting than a number of recognized planets.

(Also, I'm confused by your response. This isn't about the moon, and the moon has no atmosphere for flying)

How does it work for an outage? With solar inverters they need to have a special island mode where they disconnect the grid, so there is no chance of backfeeding power into it and electrocuting the technician who is trying to fix it. Most inverters don't support that and have an automatic cut-off if they don't detect the grid is up (i.e. there is already 110V 60Hz there).

If you have Vehicle 2 Load you can just plug appliances directly into the car.

Many of the nuclear fanatics want it because they think it means they don't have to change their lifestyle, or because they are NIMBYs and fear wind turbines and solar farms appearing near them (but don't care about nuclear plants near someone else).

Renewables and storage are by far the cheapest and fastest option now. Nuclear is just kicking the can down the road, not doing anything for another 20+ years because "nuclear is coming".

Yes, like the Nile Delta, water flowed in from wet regions further away to the desert and near-desert lowlands, and humans began using it for agriculture. Around the Tulare Basin, there's dozens of inches per year in the mountains due to orographic uplift, but only half a dozen in the lowlands. The problem is that farmers first consumed the water from the mountain-fed local rivers and are now consuming water shipped in from as far away as the Oregon border and drawing down groundwater much faster than it's being replenished. At the same time, the mountain rivers are becoming less reliable as climate change leads to snowpack melting earlier. As it stands today, it is not sustainable. More water is being used than is long-term available.

Indeed, I have no clue what you think you were trying to prove with this link:

The conversion of this water system to a lake-and-slough wetland to agriculture began in the mid-1800s when European settlers began to build canals and diversion structures to irrigate their crops. This early irrigation infrastructure upstream from Tulare Lake slowly cut off the lake from its source waters, shrinking the lake's footprint. By 1899 - less than 50 years after irrigation was initiated - Tulare Lake went dry for the first time in history.

They were overdrawing the rivers *even before the 20th century*.

You missed the point.

A friend of mine made a tea-timer app for the iPhone. Where you enter what tea you are making and it sets the correct number of minutes. Today, people would ask ChatGPT before they go on the App Store to search for something like that. That's the point. Not what YOU would do, but what the general public does. And for Jane Doe, ChatGPT has replaced a lot of these specialty apps.

Skills are great until they aren't. The problem is exactly what you say: You can literally create a skill by telling the LLM to create a skill. Which is... why the f do I need to make a skill if the AI already knows how to do it?

Properly created skills, that include reference material, specific instructions, and expert knowledge the LLM doesn't have or that's buried somewhere under 10 layers of reddit posts is genuinely useful. But most skills aren't. I'm constantly underwhelmed by hyped-up skills that, when I look at them, turn out to be bland, basic instructions.

True, but I wouldn't read much into the 75,000 figure. Folding it repeatedly isn't the same as keeping it in a pocket, exposed to normal dust and lint, and folding it repeatedly. In other words, it's likely to be optimistic.

I'd say the flaw is that the tolerance is so tight that the manufacturing yield is unacceptably low.

"Wear-out failures aren't always different from infant mortality failures, though."
That are completely different issues, always different.

Only in the most utterly pedantic sense of the word "different" wherein you mean that by definition, infant mortality occurs early and wear occurs later. But they can both stem from the same root cause, which is a component not built with adequate tolerances. In other words, they can be the same fundamental issue, just expressing themselves at different times.

That would be reflected in a low MTBF rather than the example "MTBF of 600000 hours".

Most products don't have an MTBF. And things that do have MTBF are based on accelerated wear testing on a small number of units, and can have almost zero basis in reality. There was one model of major brand hard drive about twenty years back where a couple of RAIDs where I used to work got lost because the drives all died after such a predictable number of powered-on hours that by the time you could re-stripe the RAID, the next drive would die. They ended up making sure the drives had a high variance in powered-on hours before using them in RAIDs after that.

Do you really understand what that means? Because it seems clear you don't.

It's an example that proves or demonstrates a point. And the point it was proving was that the same root cause can be responsible for both catastrophic early product failures and premature deterioration-related failures.
