Little spider makes big-spider-puppet CLONE of itself out of dirt

Re: Ichneumon wasp

@JDX

Have a read of this, mate:

http://www.stephenjaygould.org/library/gould_nonmoral.html

The whole ichneumon wasp subject benefits from knowing the context of the arguments at the time (people being threatened by a lack of 'morality' in nature), and in this Professor Gould comments upon the human reactions to it, before concluding:

[It is amusing in this context, or rather ironic since it is too serious to be amusing, that modern creationists accuse evolutionists of preaching a specific ethical doctrine called secular humanism and thereby demand equal time for their unscientific and discredited views.] If nature is nonmoral, then evolution cannot teach any ethical theory at all. The assumption that it can has abetted a panoply of social evils that ideologues falsely read into nature from their beliefs — eugenics and (misnamed) social Darwinism prominently among them. Not only did Darwin eschew any attempt to discover an antireligious ethic in nature, he also expressly stated his personal bewilderment about such deep issues as the problem of evil. Just a few sentences after invoking the ichneumons, and in words that express both the modesty of this splendid man and the compatibility, through lack of contact, between science and true religion, Darwin wrote to Asa Gray,

"I feel most deeply that the whole subject is too profound for the human intellect. A dog might as well speculate on the mind of Newton. Let each man hope and believe what he can."

[Stephen J Gould guest-stared in an episode of the Simpsons as himself, taking money money from Lisa to perform a test he then doesn't carry out, before running off laughing. He was not too proud to portray himself as a fraudster, when in fact he was far from it]

Re: IT connection

Another IT connection:

Some spiders can up the resolution of the eyes by introducing vibrations to them. Imagine you took a photo, and then shifted the camera to the left by half the diameter of each CCD receptor... and then shifted it up by the same. You would have three images that could be interpolated to resolve more detail than any one single image. Some engineers have built cameras based on this principle.

Re: So, presumably

Well spotted Hugo. The researches didn't mention it, but there are some advanced sexual behaviours in some species of spider. 'Dancing' on a web, for example... though it has been observed that some male spiders get it on with the female while their competitor is still showing off... all the gain for no pain (save being eaten alive by your mate). This is an example of biologists call 'sneaky fucker' behaviour. Please excuse the f-bomb, but seriously, that's what zoologists call it.

Yep, 'belief' is a way of making information processing efficient enough for our brains to handle it. If I had to build everything up from a priori sensations every time I made a decision, I wouldn't get anything done. Actually, I probably wouldn't be dissimilar to a newborn baby.

Re: ummm

Yeah, just to clarify: 'Mimicry' applied to 'hover-fly looks like wasp' is not the same as a child mimicking their parent's turns of phrase. Mimicry in that sense does in nature- Mynah birds, parrots and song birds being easy examples.

Re: So, presumably

Indeed, some countries have bird-eating spiders (though that is in part due to the small size of some birds in some parts of this ever-surprising world).

Hmm, it might not be that the predator is threatened by the big decoy 'spider', but rather chooses it as the bigger meal, giving the real spider a chance to escape.

Re: Brilliant

@AC

Nothing is proven. Even stuff you think is. For example, the internal angles of a triangle do not add up to 180º, but they add up to [180º] * [a function of the area of the triangle]. However the discrepancy between this theory and the actual sum of the angles is less than the diameter of a hydrogen atom if the sides of the triangle are a lightyear in length. Therefore, this discrepancy between Plato's idea and reality does not prevent it being a VERY useful theory.

Similarly in the case of natural selection, it gives biologists a theory of antibiotic resistance in bacteria, which in turn informs health policy. Not quite replicable and repeatable, but close enough to Occam's Razor and Leary's Reality Tunnels to be getting on with.

Personally, I believe the world was created 8 minutes ago, and memories I have of the world before then have been placed there by His noodley appendages. See http://en.wikipedia.org/wiki/Russell's_teapot

Re: So, presumably

@jai

Your girlfriend's instincts are good. Though here in the UK there are no spiders that can do us serious harm, that is not true of much of the world. She, like all of us, have ancestors that have lived amongst spiders since before we were small furry things.

Snakes, similarly- there are many species that can harm us if we threaten them, and our instincts 'know' this. In some people (Indiana Jones, for example) this fear is stronger, and harder for our concious minds to overcome.

I've heard it said that the sale of lion poo is prohibited in the UK after the poll tax riots when protesters used it to scare police horses. Horses might not have lived on the continents as lions for a few thousands of years, but their instincts tell them that this smell is associated with something to be avoided.

Re: So, presumably

The textbook example of this happening in short time scale is that of moths in England over the historical period known as the Industrial Revolution. Moths (nocturnal, so inactive during daylight) would rest against the bark of trees, appropriately camouflaged to the species of tree they preferred. Soot from the burning of coal ('dark satanic mills') darkened the appearance of trees in many areas, and this placed a strong 'selection pressure' on generations of moths- favouring those that exhibited a mutation that made them darker. Pale moths would be readily seen by birds and promptly eaten.

This happened in decades, if not years. Moths, like spiders, have many, many offspring.

If billions of years seems to short a time-scale, please do bear in mind that there are other mechanisms in place- not least sexual reproduction. Sex not only allows beneficial mutations to be shared around, but, in the case of this spider, could also accelerate the process: If a female exhibits a preference for a male spider that makes decoys, her offspring will not only have the genes for that preference, but also the genes for the subject of that preference.

Also, mutations don't have to create everything 'from scratch' every time... say for example, an animal population had colonised a perfectly cave system... there would no longer be a selection pressure to retain eyes. The genes for the eyes wouldn't be 'deleted', but rather they would no longer be preserved against random mutations- and over many generations the eyes would diminish and disappear. These mutations might be small, but would prevent the eyes from developing. An analogy would be changing a few bytes on your HDD's table of contents that would render it unreadable- but most of the HDD's data is still there. Should this blind animal population find itself in an environment with light, a few mutations over generations might reinstate eyes- the 'building blocks' are still there. By the same process, 'throwbacks' occasionally occur, such as humans with vestigial tails, or Julius Ceasar's five-toed war-horse.

A mutation might also be along the lines of changing 'Goto 10' to 'Goto 20', and thus place, say, an enzyme in the 'wrong' place. It is thought such a mutation replicated an enzyme found in the eye (to break down foreign substances) into the digestive tract of bovines, allowing them to break down cellulose and thus digest grass.

It is endlessly fascinating, and I would recommend Stephen J Gould over Richard Dawkins should you want to read more.

Re: ummm

Spider mech warrior? Where have I seen that before? [ insert JPG of that boss from Doom here]

Alas, mimicry as a survival tactic (birds that look like the plants they perch on, flowers that resemble female insects so that males 'mate' and thus pollinate them, hover-flies that look like wasps, butterflies that have large 'eyes' on their wings, stick insects that look like sticks...) arises from the successive selection of randomly occurring mutations.

Speaking in Tech: Like Kinect - only a THOUSAND times better

The Leap device of the headline looks very interesting- I have posted in Reg forums before about the Kinect not fully reaching its potential for content-creation applications, but this Leap device appears to have got a fair few peoples attention, and generated some interesting discussions, from the specific (does it work with X? could it do Y?) to the more general:

https://forums.leapmotion.com/forum.php

For now, they state that their focus in on hand/finger tracking (I've seen 3rd party demos of the Kinect doing similar) rather than the '3D object scanner on the cheap" that have also been demoed using the Kinect. Interesting times if you're into computers and making things.

They don't say exactly how it works at this time, but it seems to do its thing by different means to the Kinect, and with far cheaper hardware.

I was under the impression that MS is considering contact-less gesture controls for future laptops, but haven't heard anything lately due to all the noise around Win8. Oh, re OS choice, Leap say "At this time, our focus is on Windows and OS X, with Linux being on our agenda." It is encouraging that they are still platform-agnostic, and haven't been bought by a big player as FingerWorks (multi-touch gesture-based input devices) were by Apple.

Fingers crossed that it is as good as it seems and it takes off.

No really, please do expand on your reasoning.

(do bear in mind that any price difference between PCs and Macs is no more than a few hundred dollars if that, whereas even the most basic 'upgrade' package on a new car, for example, is far, far more. Hell, in the UK, Ford charge £250 for a wretched DAB radio to be factory-fitted to your new Focus, never mind fancy wheels, leather upholstery or upgraded sound system etc. A slightly nicer house? Thousands. A couple eating out once more per month over a year? One extra pint of beer per week, over a year? Hundreds. You don't need a spreadsheet to get the gist.)

Tom's Hardware would disagree with you. I could take your word for it, but Tom's were good enough to show their working and you weren't. Sorry. Obviously the UK case is different, because exchange rates can up the margins, but this study was done by a US organisation.

Generally though, Mac users are more likely to be baby-boomers with some expendable income, their children are grown up, house is paid off etc... people who probably didn't use digital technology from a young age. Remember- for every objectionable hipster with a Macbook in a coffee shop, there will be a dozen Macs in the homes of perfectly pleasant people who don't get worked up about technology for its own sake, but do whatever they do in one of the myriad other areas of worthwhile human activity besides IT.

Causing riots at funerals? Like shouting 'Fire!' in a crowded theatre, no?

Free speech is about being able to challenge your rulers without being banged up in prison or beheaded. It is not about being a prick.

Likewise, freedom of the press is about bringing politicians and institution's to account- it shouldn't be about harassing innocent citizens for the titillation of others.

Re: "Protest the funerals"?

Actually, all New Testament bibles have the line "Treat others as you yourself would be treated", and "Blessed are the peacemakers". Kurt Vonnegut, a former head of the Atheist Association of America*, has made a great case for living in a world in which the Sermon on the Mount happened.

Christianity started out as the religion of the poor, under the Roman empire. For much of the last two thousand years, political views and movements have been expressed in religious terms, culminating eventually in the enlightenment, a milestone of the very civilisation that has shaped your views.

You make me embarrassed to be an atheist.

Loius Theroux and Keith Allen have both visited them... Theroux did better, since they couldn't quite work them out.

Seagate slips out super-silent 2.5in video hard drive

>Not suitable for HD recorders then!

I beg to differ... many people use PVRs to watch weekly broadcasts at times convenient to them, and then delete them. If you want to store the recorded footage 'for keeps', then you would have to take steps to transfer it to additional storage anyway, because one day that single HDD will fail. I believe there is PVR firmware which allows content on a PVR HDD to be transferred to other devices on the network.

For 'normal people' who don't tinker with their toys, all a bigger PVR HDD means is that come the day it goes Pft!, they lose more hours of the recordings they have made.

[Disclaimer: I'm not advocating illegal duplication of copyright material, but the above is a technique that allows broadcast material to be retained for reasons that fall under fair use provisions- such as academic use or parody. ]

Re: Computer Models!

>Environmentalism is a religion, a kind of Doomsday Cult. It is probably the most popular religion in San Francisco.

Do you mean that ALL people who are concerned about the issue are zealous nutters? I'm an atheist, yet I do not kill, do not steal, and keep the clean separate from the unclean (food safety). Similarly, I'm not a member of Greenpeace or whatnot, yet if I were a town planner, I would sooner approve a building that was kept at the desired temperature through the use of design and materials over one that relied purely on fuel heating and powered air-conditioning.

Just as there is a lot of common sense in the scriptures, (on how not to get food poisoning, on how not to depress yourself by coveting your neighbour's wife's ass, or creating ill-feeling over the above) there is some common sense in being less wasteful and at least studying potential alternatives. This isn't faith- how long have aluminium smelting plants been built near hydroelectric plants? For decades.

Trying to tar all environmentalists, or even the the yet-undecided, with the same derogatory brush is like comparing your local vicar with Jim Jones of suicide cult infamy or the Spanish Inquisition.

Even termites can construct structures that only vary by 1ºC over a 24 hour period, and they're insects. Can't we build a little smarter? If we looked at Moorish architecture, with courtyards, water features and thick walls, we would be doing better than just erecting another condo with a hundred Mitsubishi air conditioning units hanging out of the windows. I'm not saying we currently have the solution, but we can do better than "we need air con, so let's give up now". Still, what with Florida being filled with AC-dependant senior citizens, and their enthusiasm for voting, it could be a struggle...

> this seems like mindless vandalism to me...

Maybe it is, but the first thing to do would to explore how likely the following two assertions are to be correct:

-The engineers have a reason to do what they are doing, but subtleties of their reasoning have not survived the journey through a Reg article... or

-The engineers are mindless vandals.

My first assumption was that it was being done to study the resulting impact, but the article says that won't be seen at the time. Maybe it is enough for them to study the crater/ejected material after the event, but they are destroying the second probe soon afterwards. Maybe it is just some house-keeping, keeping junk out of orbit so as not to pose a danger to future missions to the Moon (however small a chance). Dunno.

Windows 8: At least it's better than ‘not very good’

Re: Win 8 FTW

Vista would force restart your computer every so often, to install updates, wiping unsaved documents (avoidable) and killing any long tasks like batch rendering or downloading (unavoidable). This behaviour couldn't be turned off in the Home versions. Personally, I consider that to be more annoying that having to bat some coloured squares out of the way on start up.

Re: Windows 8 is basically a waste of time

>But there's literally nothing that would make you want to go through the hassle and expense of installing 8 when you have 7.

I'll take your word for it, as I'm happy enough with Win 7. That said, I haven't any USB 3 hardware, or any need yet to explore Storage Spaces. Lots is written about the Win8 UI, (I'd just assumed that technical users will use 3rd party tools modify it to their liking... surely 'power users' have their own pet tweaks they like to make to any GUI?) but less about the 'under the hood/bonnet' new features/bugs.

I kind of get the impression that MS knew many people would be happy enough with 7 not to bother with 8, so they have been more experimental with 8's UI, with a view to implementing the resulting feedback into 9. This view is deliberately optimistic, though!
