  1. Re:We have something similar in the UK... on Tracking Your Cell Phone for Traffic Reports · · Score: 1
    Maybe I'm not fully understanding this, but with all that "in-and-out" tracking of partial licemse plate numbers and parsing time differences, etc, isn't is far simpler for those machines to simply measer the speed of the cars coming at them in real time (as opposed to delayed time) and report that figure?

    I suspect that you're right about not fully understanding the system. The speed of cars coming at the sensors in real time is going to be approximately zero for half the time. (At some junctions, it'll be more than half the time.) The devices are situated at traffic lights, where the right-of-passage shifts from route to route every few (tens-of) seconds. So cars passing the sensor are either braking to a halt, accelerating from standstill, or driving at reduced speed through the junction. The point of measuring the "time of flight" between junctions is that the measurement will be much less affected by the relatively low speed at junctions.

    You're right about the privacy implications of mobile telephony having been well covered on SlashDot before. I remember it being discussed as a serious restriction on people's willingness to use this technology back in the 1980s when the technology before this was being developed. However, it appears that people have actually been willing to give away this information, and the technologies have become popular.
    It is possible to have some of the benefits of mobile telephony without giving away much information about your movements : (1) switch the phone off by disconnecting the battery, travel to a location from which you wish to make a call, switch the phone back on, make your call, return to step (1). What you can't have (using GSM or the analogue systems it replaced) is absolute privacy and the ability to receive calls at random times and locations. You have no option, in the GSM system, but to trust the operator to not release this data.
    Whether the government (any government, anywhere) would permit the deployment of any mobile telephony system that did not give them access to this sort of information is moot. I doubt that I would, were I in a position of power and responsibility.

    synthetics have a mix of 8 (which is normal) and 4 (which is not) sided internal structures


    Actually diamond is a pure carbon crystal with 4-sided (tetrahedral, 4 equilateral triangles) structure grid, unlike other naturally occuring elementary pure carbon mineral, graphite, which has hexagonal prismatic grid (8 sides: 6 rectangles connecting two hexagons).

    Therefore, it is assumed that you made a slight permutation in your comments: for a diamond, 4 sided grid cell is normal, 8 sided grid cell is not normal, but it would be normal for graphite, cheap mineral which is likely a base material for synthetic diamond.


    Someone is getting confused over 2-dimensional and 3-dimensional cells in elemental carbon, while someone else is unaware of the Platonic solids which have cubic symmetry.

    The commonest natural form for diamonds to take up (due to the comparatively slow growth rates of the {111} form of the diamond structure) is the octahedron, which has 8 identical sides, each an equilateral triangle. The tetrahedron (4 faces, each an equilateral triangle) is not normally found as a natural shape of diamond crystals (I can't think of an example, but I have heard of stellated octahedra being found, which in an extreme could resemble tetrahedra. Be weird though.) Octahedra have 4-fold axes of rotational symmetry that tetrahedra don't have.

    I thought Neanderthal was classified as a large modern human that had arthritis.


    I'd like to know what your sources for that opinion are. So that I can avoid them.

    The Neanderthal race appeared in the Levant (follow the sound of landing shells and Uzi-fire) and europe some time after the first appearence of AMH (Anatomically Modern Humans) in Africa; they were shorter in height, but deeper of chest; more strongly muscled; It's a toss-up who weighed more.

    Most adult fossils from this pre-modern period had significant wear and tear on the bones and joints. (Note - I do not restrict my statement to hominids, or primates, or mammals. It applies to all skeletalised animals. Concerning skeletalised non-animals ... I'd have to think about that.) These days it might be attributed to arthritis, but I doubt it, because few anatomists today would be incapable of recognising the skeletal marks of hard, lifelong, physical labour. It may be an uncommon lifestyle this century, in the West, but for the overwhelming humanoid population through the history of our genus the choice of lifestyle has been "death" or "grinding grunt labour, every day".
    (That said, some AMH fossils, and some Neanderthal fossils, have been found with abnormally badly damaged bones by the standards of their contemporaries. This is indicative of social care of the crippled, invalided and elderly. These were our relatives, beyond doubt.)

    I had a conversation with a fool last week who denied the existence of fossils at all, and did not believe me when I said that I saw no reason for believing in any sort of god or gods. (How he knew the state of my internal thoughts better than I do is left as an exercise for the reader.) Popular speech habits might tempt me to describe this dull-witted braggart as being a "Neanderthal". But since Neanderthals had (on average) larger brains than AMH, complex societies, and an understanding of their fellows as thinking, feeling, empathising individuals, then describing this idiotic god-botherer as a "Neanderthal" would be an insult - to the Neanderthals.
