  1. Re:I see immediate practical applications. on Tractor Beam Created Using Water Waves · · Score: 1

    Sucking has rather short range unless you collect a lot of water, which in turn means high energy needs. I don't know what the energy demands of a wave-sucker would be, or some form of hybrid device, but there may potentially be a saving. It could also be done using fewer moving parts, as the oscillatory motion of a wave-maker is achievable with just a magnet and a coil. You'd want to pump it at the natural resonant frequency for maximum efficiency.

    I'm imagining this as an improved skimmer, using the waves to increase collection range for a cleaner pool or improved efficiency.

    The justice systems of most countries have little focus on rehabilitation. While the term justice might sound noble, to many people it is just a polite way of expressing a desire for collective vengence: there is a natural urge to see evildoers made to suffer, and giving them access to education and counciling is not suffering.

  8. Re:Time to hermeticly seal the drives on Police Using Dogs To Sniff Out Computer Memory · · Score: 1

    How much of the house would be left before they gave up searching if there was nothing to be found? Police do not like suspected criminals, they aren't going to be gentle. If I were hiding a memory stick I would hide it inside the float valve in the cold water header tank, cut along the seam and melted back together. So if they were really being through enough to find something like that they would have to be ripping apart the plumbing. I wouldn't be surprised if they carry out some deliberate destruction for purposes of intimidating the suspect, hopeing they will confess in order to avert property damage.

    It's not the dog that decides if the car contains drugs. It's the handler. If the handler wants to see a search carried out, the dog will find something suspicious.

  10. Re:Amazoing on Police Using Dogs To Sniff Out Computer Memory · · Score: 4, Informative

    That's called 'parallel construction' - the practice of fakeing a source in order to conceal the real source. It's used to protect informants by allowing for plausable deniability, giving the appearance that the police stumbled upon a crime by other means or sheer luck.

    It's still controversial because it can also be used to aid the police in using illegally gathered evidence while concealing that fact from a court.

    The pro-life movement is full of bad science, mostly owing to a very strong confirmation bias. Chief of them is a widespread belief that abortion causes breast cancer (A link denied by just about ever mainstream medical association that has anything to do with cancer), followed by a long list of the dangers of abortion. A good part of that is due to reporting bias - every time a woman has any type of serious complication following abortion, it gets plastered all over the pro-life campaigning organisations media sites* - all the better if there is a hint of malpractice involved. In much the same way that media saturation of every child abduction convinces parents that every strange man is a pedophile, this creates the impression that abortion is an incredibly dangerous procedure - when the truth is that, statistically, the mortality rate for abortion (even the late term) is a fraction of that for completed pregnancy and birth.

    If this fails I'm just going to switch back to PLA. I'm only using ABS for this because I've not got much PLA left to hand right now and want to practice getting large ABS prints to work. In my experience PLA is much less prone to warping.

    Depends on your printer. I've one of the low-cost ones, a K8200, and it is unreliable enough that it needs supervision. Still, for four hundred quid, I'm very happy with it. I imagine if I'd paid up for the thousand-plus-quid high end models it'd work much better. ... and I hear the fan running. That's supposed to be disabled for ABS! I'll go pull the cable out for it.

    I'd add 'reliability' to that list. 3D printers currently have no feedback: If something goes wrong they keep shooting noodles. That means they need to be supervised, and for many prints there is an element of luck so it might take some hours to get a good result. I'm on attempt three to print a small box right now - the first two failed due to bad adhesion. I've just put down new kapton, but this one is already looking iffy.

    I think the edges of the print bed are cooler than the center, causing warping.

    I've seen many systems put forwards as proof of intelligent design. I've also seen them all explained as products of evolution. Though it doesn't matter: Even if a system were found which seems un-evolveable, at this point it still wouldn't disprove evolution to the point the whole theory gets thrown out. There's just too much evidence in favor - at most, it would suggest there is some small detail of the theory that remained incomplete.

    It could work if it was done according to proper scientific management. The historic approaches tended to involve determining that the lowest social classes somehow happened to carry all the bad genes.

    A more modern approach could be, for example, tracking down everyone who carries a Huntington's disease gene and offering them free sterilization, and the promise of access to PGD should they wish to breed in the future (Or, if you're on a budget, you could just kill them - either way works). Thus an undesirable trait is eliminated.
