  2. Microsoft dropping Intel? on Apple Updates Power Mac Line · · Score: 1

    I have a more plausible rumor. Microsoft has abandoned Intel for the XBox, and is using a PowerPC family chip instead (this part is fact, not rumor). Presumably, this means that Microsoft has already implemented much of its core OS technology on the PowerPC chip. So why not go all of the way, and release a PowerPC native version of Windows with the next generation of VirtualPC? Microsoft could offer PowerPC native versions of its office apps, while apps that have not yet been recompiled to run natively in PowerWindows could run in emulation (as with the current version of VirtualPC) but with the speed boost of a native PowerPC Windows OS.

    Why does it obsolete the HD TiVo?

    Well, it doesn't really, at least not yet. Initially, DirecTV will be using the new MPEG-4 satellites to deliver local HD channels, which HD TiVo owners currently get over-the-air (the HD TiVo has two over-the-air tuners). The HD TiVo is unable to decode MPEG-4 with the current hardware, so it will be unable to take advantage of the new channels, but HD TiVo owners will be able to continue to get them over the air.

    However, in a couple of years or so, DirecTV hopes to convert all HD channels to MPEG-4. This will leave HD TiVo owners only able to record over-the-air HD broadcasts. DirecTV has indicated that they will provide an upgrade to HD TiVo owners. Details have not been announced, but it is widely suspected that the "upgrade" will be to a non-TiVo HD DVR, which DirecTV is known to be developing.

    DirecTV has yet to announce what they will be doing regarding current HD DVR customers or when, except that some sort of upgrade will be available eventually. DirecTV and TiVo both claim that their association is continuing, but DirecTV is also developing their own DVR. It is widely suspected that DirecTV hopes to substitute their home-grown DVR for TiVos, and that any upgrade may be to DirecTV's own system, but nothing has been announced. Whether Comcast's recent deal with TiVo will affect this remains to be seen.

A recording may be useful to students studying for exams, either to jog their memories or if they couldn't attend to lecture and want to know what I emphasized. But it is not the same as being there. Most of the time, if I have a choice between listening to a recorded lecture or reading a text covering the same material, I'll do the latter--it's simply a more efficient use of my time.

    Here is another reference to even more examples of speciation. Here are still more . As you can see, there are a huge number of documented examples. For that matter, different breeds of dogs would undoubtedly be considered to be different species if encountered in the wild. We call them "breeds" only because of their origin by artificial rather than natural selection. A great dane and a chihuahua are morphologically more different than a coyote and a wolf, and, being functionally unable to breed, meet one definition of different species. But of course, one can always demand something "bigger." If somebody managed to breed a dog into something resembling a horse (even though such large changes are thought to take millions of years rather than 3000), Creationists would no doubt demand an elephant.

    Genome sequencing studies in recent years have demolished the notion that there is any real distinction between "micro" evolution and "macro" evolution. At the genetic level, they are no different--"macro" evolution is just more of the same.

  15. Re:Finally! on Resurrection Ecology Gives Life to Old Eggs · · Score: 1

    Most rational creationists accept that micro-evolution - the development of new species, sub-species, and distinct populations - occurs regularly, thanks to adaptive survival and the remarkable propensity of the genome to re-activate inactive DNA. I remember a recent example where a species of bacteria unable to digest lactose developed that ability within a few generations after being grown in a lactose-rich solution. The bacteria didn't gain this ability through random mutations, but by the activation of a previously unknown gene in the "junk DNA" part of the genome.

    Yes, the microevolution dodge is a common tactic of creationists. Since there is no actual distinction between microevolution and macroevolution (as genetic studies show that the genetic changes that occur in so-called "microevolution" as exactly the same as the differences that divide species), Creationists are always free to dismiss every observed example of evolution as "micro" and demand something "bigger."

    Activation of so-called "junk" DNA is one predicted mechanism of evolution. A gene gets duplicated, and the duplicate copy is then free to mutate, since the duplicate copy is no longer required for life. It can then pick up a new function. Genetic studies have shown that most proteins fall into families created by exactly this process of duplication and mutation.

  19. Re:Adjusting definitions on Optical Computer Made From Frozen Light · · Score: 1

    Furthermore, shadows (absence of light, or the process of 'shutting off' of a light source) absolutely follow the rules of light travel and are not known to ever, even trivially, have traveled faster than the speed of light (in a vacuum).

    There are lots of things that "travel" faster than light, including a shadow or sweeping light beam. What they have in common is that there is nothing physical actually traveling faster than light; what appears to be traveling is more like an interference phenomenon. For example, when a light beam sweeps across space, at great distances the reflection of the light beam sweeps across objects faster than the speed of light. But no photons are moving faster than light, because the photons that make up the reflection at point A are not the same as the photons that make up the reflection at point B. Furthermore, any change of the sweep speed propagates down the beam at the speed of light.

    Quantum entanglement absolutely does, and has already been shown to 'violate' the faster than light travel theory.

    The sorts of "information" that can be transmitted faster than light by quantum entanglement are highly constrained, and have a lot in common with the apparent movement of a shadow, in that they do not permit an arbitrary message to be transmitted faster than light of the sort that would permit violation of causality, even if transmitter and receiver are traveling at high velocity relative to one another. If arbitrary information can be transmitted faster than light, then it is possible to conceive of circumstances in which you can send a signal with content "do not send the signal" back to yourself, such that the signal arrives before the time when you sent the signal.

    Instantaneous, does have a definition and denotes something that happens concurrently

    This is merely a synonym. However, in relativistic physics, instantaneous (or "concurrently" if you prefer) only has a unique meaning for something that happens not only at the same time but at the same place. Events that happen at different places may be simultaneous in one frame of reference, but not in another.

To be sure, in Darwin's time the eye seemed miraculous enough that Darwin felt obliged to devote a special discussion to how it might have evolved by selection.

It is almost inevitable that in a mostly transparent life form, the activity of some nerve cells would be affected by light. Given the extreme selective advantage to sensing light, evolution of light sensors of increasing sophistication seems almost unavoidable.
