Comment Re:No Plate Tectonics (Score 1) 45

Since there's no evidence of any plate tectonics whatsoever like Earth,

Venus doesn't seem to have the same tectonic style as Earth. At the moment. Beyond that ... I'm not going to speculate geologically. (Or even Veneraly. Or Venialy.) One thing that we don't know is how many different styles of planetary tectonics are possible (or if the number is significantly lower than the number of planets).

that heat from tidal forces etc. that builds and dissipates any normal magnetic field...?

Doesn't work : the magnetic field of Earth is generated in the core at temperatures several thousand kelvin above the temperature at which the permanent magnets which you seem to be thinking of cease to work. The Earth's magnetic field is thought to be the result of a self-exciting dynamo - which doesn't have an upper temperature limit, they operate just as well in plasmas in the many thousands of Kelvin, and in fresh neutron stars at approaching a GK (giga-Kelvin ; no, I'm not joking.).

I'm guessing here.

But you're admitting it, which is bizarre and unusual behaviour for Slashdot, and suggests that you might actually learn something.

But facebook wants to become one.[a public square]

Oh, I seriously doubt it. They might want to e perceived as a public square, or to morph people's concept of a public space into "something like Facebook, but with weather and pigeon shit," but that is a very different aspiration.

For a start, in a public square, you don't have to pay an entry fee, and you don't have to look at adverts. That in itself would be a financial death knell for Facebook ,if they were to become a "public square".

Death isn't a necessary part of evolution. Variation in reproductive success (for whatever reason) is what drives evolution.

But I suspect that if you're touting glib comments like that, you either don't understand evolution, r aren't interested in making comments that have some connection to reality.

Of course it saves the rhinos. You put 100 times more fake stuff on the market and the price for rhino horn collapses, meaning people stop hunting them.

The brilliant part is that this makes use of something that's normally a bad thing - China's extensive peddling in fakes - to achieve a good result. I doubt it'll stop the really high end of the market, the sort of people who would instruct their buyer to send what they buy sent off to a lab (I don't think some rhino DNA alone would fool a lab, surely it looks different under microscopic examination), but for the rest of the market, it's a neat idea.

Why do you think over a dozen observatories have been built there? Think it's cheap to sent giant pieces of delicate scientific equipment from the mainland? TFA doesn't even mention the actual reason why Mauna Kea is one of the best places on the planet for optical telescopes: seeing conditions (aka, how much celestial objects "twinkle" on average. Outside of deep Antarctica (Dome A, not far east of the South Pole), there's no other better known location on the planet (a couple are pretty close, like La Palma and La Silla, but none exceed it). Good seeing requires high altitude with the area around being as perfectly flat and uniform as possible for hundreds of kilometers.

For optical telescopes, seeing is the most critical factor for resolving fine details. And this telescope is all about resolving fine details. Adaptive optics help counter seeing problems, but the better your seeing baseline, the better the final result.

They put aceteminophen in Tylenol on purpose to kill you if you try to get high on Tylenol. They don't need junkies messing up their reputation.

erm.. excuse me but Tylenol is but a trademarked name.. the generic name of it is...Acetaminophen....

so the fact that it's got Acetaminophen isn't surprising..... as that's what it is!

The move is likely to concern online publishers who rely on advertising to generate revenue.

Choose a phrase composed from the following words in any descending alphabetical order : "shit" ; "tough."

If loss of advertising revenue means that I have to choose which websites to pay for my news, mail service, etc, then that's just dandy and fine. Oddly, when I go to the cinema to watch a movie, I choose which one I want to watch then pay (and annoyingly still get some adverts, but by turning up 20 minutes late I can avoid that). When I go to the newsagent, I choose which newspaper I want to read, then buy it. What is different about the web?

Does anyone want their div by zero errors to result in anything other than zero?

I want a divide-by-zero error that occurs in properly validated data to result in a HCF command being carried out.

Further more, I want people writing code for me to actually understand what they're doing, and to analyse their algorithms so that they check data going in, and trap for errors. Yes, it's time-consuming and difficult. But it's also necessary.

Comment They're working for Uber (Score 1) 180

The Russian government still denies any involvement of Russian troops in the fights in Ukraine.

The Russian Government is subcontracting many of it's army to Uber, on an hour by hour basis. Whenever they're in the Ukraine, they're actually touting for business to move Ukrainians westwards.

Their advertising tactics are a bit more dramatic than the average "chugger" though.
