[SIGH] Is suspect that I've got a god-squaddy (or someone who has been "educated" by god-botherers) here. But...
Death happens whether or not there is evolution in your species, ecology, or whatever your experimental system is. You can have an evolving system and a non-evolving system with the same death rates (organisms dying per day, percentage dying per day, pick a metric) and the death [count or rate] will not distinguish between the two systems. Deaths are not a determining characteristic of an evolving versus non-evolving system.
Deaths are however a way of distinguishing between systems with living organisms and ones without living organisms. The death rate in a system with living organisms is not going to be lower (on the medium to long term) than in the system without living organisms.
Since you seem to be trying to make points straight out of the goddidit handbook, I'll be very explicit about the final step : what determines whether a population evolves is whether some blood lines have higher numbers of offspring surviving to reproduce than in other bloodlines. If there is that differential, then the population will evolve to be dominated by the faster-reproducing bloodline even if the death rates for the two blood lines are identical. If there is not that differential in reproduction, then there is no evolution in that population.
I suppose I could rebut you by asking for your example of a living system which does not have death in it. But that would leave the door open for you to take the goddidit's excuse that "I'm not a biologist", as if that were any sort of excuse for not learning about biology before making comments about it.
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.
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.
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.
Yeah, I was deconstructing that part of the article, and the objections to it, and wondering if it was worth the effort. Then something came up and I had to go and attend to the real world.
Sloppy writing by the journalist, and unjustifiably sensationalist claims. So unheard-of.
The question of the day, how long till someone links imaging processing software with the guidance system so they can get the drones to hover over, and follow along, as sharks patrol off shore?
And the question of the day before - or at least, the question of the feasibility phase of the programme - is : is swimming at shallow depth a sufficiently common pre-hunting behaviour amongst all types of dangerous sharks in this particular area, that the behaviour is a sufficiently good predictor of attack to be worth the effort.
Or, to generalise it further (because this is not a new discussion), what is the false positive rate (beach alarms blaring "get out of the water", tourists scared and not returning, businesses going bust, but no subsequent attack even amongst the remaining vulnerable population) compared to the false negative rate ("is that a shark, or just... nah, it's just seaweed" - or electronic version - no alarm, chewed tourist) for this screening test? And yes, I am deliberately using terms comparable to testing medical screens, because this is not a new debate.
While I'm not a shark behaviour specialist, as a scuba diver who first entered the sea in the years when Jaws was still a fresh movie, I have paid a little attention to the subject. Some shark species cruise just below the surface and are highly visible to detection like this. And some don't. Indeed, some individuals of some species would be detectable like this one morning, and change hunting strategies ten minutes later.
The idea has merit - don't get me wrong - but that doesn't mean that it will actually work well enough to be worth the effort on it;s own. Possibly as an adjunct to a "lifeguard drone" service looking for people in trouble in the water, pollution, fights on the beach, etc, it could be justified. But for just this one task - I doubt it would be worth the effort.
There is a good argument to be made that the oceans are the shark's territory, and us humans should be a damned sight more respectful of their right to life liberty and the pursuit of black seal-shaped food. I don't consider the seas to be my own, and I probably spend more time working on them than most people here. Next month my transport to work is likely to change to the extent that I'll need to worry about dying of shark attack instead of hypothermia, if the transport crashes. Concentrates the mind wonderfully, the thought of dying on the way to work.
then I guess you're fine with the price of a reasonable laptop suddenly skyrocketing from $500 to $2,500 on grounds that
That would only work if it applied to ALL laptop vendors. For my personal needs (I'm considering the possibility that I MAY need a laptop with a better-than-SVGA graphics card with some sort of "hardware acceleration". But since I've never knowingly used such, I've still very vague on what that means - is it newer than 2000, or newer than 2005?), second (or third, or fifth) user remains perfectly fine and runs an awful lot cheaper than buying new.
On that basis, I see the "EFI/ UEFI boot problem" as being something that I may have to deal with the other side of 2020. When my next laptop may be feeling it's age.
It's peculiar though - he's not done a lot for several decades until having a recent flurry with the "World's" books. Which are OK, but hardly up to the standards of his previous work.
I guess that the "Damon Knight Grand Master Award" is some sort of lifetime achievement award. [Googles]
[It] is a lifetime honor presented annually by the Science Fiction and Fantasy Writers of America to no more than one living writer of fantasy or science fiction. It was inaugurated in 1975 when Robert Heinlein was made the first SFWA Grand Master and it was renamed in 2002 after the Association's founder, Damon Knight, who had died that year.
OK, fair enough. I read his most recent, "Bowl of Heaven" and thought "I've read this before. Several times." It's a fair enough book of the form, but it's hardly ground-breaking. Given that it came out of Niven and Benford, I was somewhat disappointed, and hadn't decided whether to get the second part.
Since it would remove one lump of orbiting hardware from the Solar System which would otherwise end up being an un-tracked bit of debris, then that is a non-trivial argument for them trying this. Otherwise who knows what orbit the spacecraft would end up on?
Eventually, as the comet erodes, then both parts of the spacecraft would end up in orbit, but within the (mildly unpredictable) envelope of the comet's other natural ejecta, which doesn't really add to the space-debris problem. Though where the launch cowlings etc go, I've no-idea. One would hope for re-entry, but the mission design may not have included that at build time.
But every "picture" suggests things rotate about them in an accretion disk. Which doesn't make sense if they were all pulled in from different directions
It makes perfect sense when material isn't uniformly present in all directions, as in the case when a black hole pulls matter from an orbiting star.
... or from any other source where it has an inherent angular momentum, or has AM by the relative position of the accretion disc's matter source and the barycentre of the black hole.
The final shape of the accretion disc is then going to be a complex composite of the original matter's AM, and any torque imposed on it by the gravitational asymmetries in the region around the black hole. I don't have the maths to describe it, but that has been the empirical description for several decades - possibly up to 4 decades.
the article is light on facts, but because it's misleading about the fact that it is uninformative (and only about pretty pictures), and it presents itself as tackling questions which it does not.
.... which is exactly what I've come to expect from anything from "StartsWithABang", and particularly things where she only cites a "medium.com" source.
I'm trying to figure out a way of editing out her posts from my Slashdot headline feed. Any ideas?
[to be fair - she also has a post up which links to a couple of other sources which are not medium. Which ameliorates my standing suspiscion that they're an account owned by Medium.com's advertising agency. Slightly ameliorates.]
You obviously have not ever worked with the oil and gas industry:) There may very well be thousands of families dying from poisoned water, but the oil and gas industry will scuff it off as a non-issue, just like always
The oil industry will only pay attention to problems for unimportant people, such as "foreigners".
Of course, that includes most posters here, since I don't see many Russians of Gulf (Persian) Coasters posting.
I was sitting on an oil rig watching the events (while having a "well control event," so not watching very closely. We had out own more important events going on.) on the newly-installed satellite TV. We probably know more about hydrocarbon-liquid fuelled fires than most people, because we have to be our own fire brigade. No one in the oil industry (TTBOMK) gives that "the fire couldn't reach the necessary temperatures" bullshit the slightest bit of attention. Because all to often we see that hydrocarbon-liquid fuelled fires are perfectly capable of reaching adequate temperatures.
Tension or compression doesn't make much difference to the softening point.
