    Actually, you have it almost exactly backwards. Apple used to include SCSI as a standard interface on even their low-end systems, and they were the standard method for hooking up scanners and external disks. That made them a high volume item, so the price was low. Currently, the standard methods of connecting peripherals to Macs are firewire and USB. Check out the prices of USB and firewire cables; you'll find that they're as cheap as SCSI cables used to be. Today, SCSI cables are used about equally for Macs and Wintel machines, and are purchased pretty much exclusively to hook up costly high-end high-speed disks. They are a much smaller volume item, and the people who buy them are already shelling out for an expensive disk drive, so they don't balk at paying a premium price for the cable as well. As usual with pricing, it boils down to supply and demand.

    So the well-reasoned article explaining why Apple's way of doing things is okay basically says "they're following RFC2131, so they're okay." But it is a well-known and much-lamented fact that DHCP provides no security. So if you depend on DHCP to be secure, you are not secure. At all. That's not well-reasoned, at least in my book.
    So Apple should do what? Design their systems not to work with DHCP, even though it is virtually universal and often required for network compatibility? All security is a compromise. When one uses DHCP, one is implicitly accepting the fact that one's security depends upon the ability of system administration to make sure that there are no rogue servers. There are certainly some contexts in which DHCP spoofing can be a concern--using public WiFi networks, for example--but under the circumstances encountered by most users, allowing DHCP provides a massive increase in ease of use and a negligible loss of security.

  20. Biological risk on California Bans Genegineered Fish · · Score: 1

    The odd thing is that the average person's idea of relative biological hazards is almost completely backwards. Lets consider the things we can do with living organisms, from most dangerous to least dangerous.

    (Most dangerous)
    1. Moving a wild-type organism from one place to another (or in the case of a microorganism, from one host to another).

    There is no doubt that this is a horrible risk, even though we do it all the time. There are numerous real, not theoretical, ecological disasters that have arisen this way. An organism in its natural environment is generally relatively stable (because if it wasn't, it would have long ago gone extinct). Move it somewhere else, and its natural prey and predators may be absent, and it may choose a new prey, while its numbers go unchecked because of the absence of natural predators. Similarly, most diseases and parasites are adapted to spread in ways that are not excessively destructive to their natural hosts. Move them to a new host, and the same mechanisms will not be "quite right." There are many examples of organisms that produce little or no disease in their natural host, but are destructive in a different host. Of course, when you move an organism to a new environment, you also are exposing any diseases it has to a bunch of potential new hosts.

    2. Conventional domestication by selective breeding

    Again, there are numerous examples of ecological disasters produced by species domesticated by ancient technology of selective breeding. Because such species are propagated by humans, they can have very "unbalanced" properties. The are also frequently maintained by human populations in large numbers. For example, dogs bred to hunt particular species become very destructive to those species when they go feral, even if they are incapable of surviving independently in the wild for long. Cats are extremely destructive of bird populations. Domestic animals and plants, often maitained in large numbers with limited genetic variability, also constitute a major reservoir of infection by microorganisms and parasites.

    3. Selection of targetted mutants or selective mutagenesis.

    It is possible to develop techniques of selection of spontaneous mutants that intentionally favor the development of microorganisms that are resistant to important therapeutic agents. Many agricultural and medical practices result in unintentional selection to the same effect. Targetted mutation is a somewhat more efficient way of achieving basically the same thing. Biowarfare agents developed by these methods are potentially extremely damaging if they accidentally escape into the wild. Because the genes mutated are natural genes, they are generally appropriately regulated within the organism, and do not impose a high cost on the organism, so such mutants may persist in the environment even in the absence of further selection.

    (least dangerous)
    4. Introduction of a foreign transgene.

    This is probably the least risky of all. Transgenes generally are driven by strong, unregulated promoters, such as viral promoters, and are overexpressed at substantial cost to the organism. Because the organism has not evolved to accomodate such genes, they may have deleterious physiological effects. As such, trangenic organisms typically suffer a disadvantage in the wild and are unlikely to persist. Although there is much fear of allergic reactions to transgenic foods containing "foreign" proteins, the fact is that people routinely eat novel foods containing proteins unfamiliar to their immune systems. Severe immune reactions to foods are rare, and the most severe are not to foods derived from modern methods of genetic modification, but rather from the older method of selective breeding (e.g. wheat, peanuts, milk products).

    Why do people persist in trying to lump breeding and GM together under the same "genetic engineering" umbrella? Repeat this until you understand it: Genetic traits that are expressed through breeding are utterly unlike genetic modifications that are only possible through human manipulation of a biological product's DNA.
    However, this simply isn't true. They aren't "utterly unlike." In fact, they are generally very similar. Ultimately, they all come down to sequence changes. And even if it is easier to pull a gene out of another species, there is in most cases a good chance that it would be possible to achieve a similar end by selecting for modifications of existing genes. The difference is that a transgene is far less likely to lead to "runaway" organisms than is a modification of an existing gene. A transgene is typically expressed by some strong promoter, with little regulation, so it places a metabolic burden on the organism that will almost certainly be deleterious in the wild. In contrast, a mutational modification of an existing gene that has a sophisticated regulatory promoter that has evolved in the species is far more likely to survive, and possibly create problems, in the wild.

    Like creationists, the anti-GE folks generally suffer from the mistaken notion that different species have very different genomes, and imagine that something drastic is likely to happen as a result of crossing species boundaries. In reality, the genes of different species are far more similar than different, because all species evolved from common ancestors. Most genes in one species have counterparts in another. Indeed, it is possible to find counterparts of most human genes in species as diverse as bacteria, yeast, and roundworms. Bizarre novel genes can just as easily (indeed, probably more easily) occur through mutations in a single species that splice one gene into another as through introducing "foreign" genes. The nightmare scenario of the expression of a transgene accidentally creating an "uber-organism" that runs wild and causes an ecological catastrophe makes about as much biological sense as the notion that being bitten by a radioactive spider will confer upon one the ability to climb walls.

    Selective breeding has limits that could arguably be called 'natural'. Ex: you can't breed a lima bean with a dairy cow, yet you could splice genes between the two organisms. Selective breeding and direct manipulation of DNA are not the same thing at all.
    That might make some kind of sense if genes never moved across species without human intervention, but that is not true at all. After all, "genetic engineering" was invented by viruses long before people got around to doing it. Even naked DNA can be infectious under certain circumstances.

    There is nothing magical about moving genes from one species to another. Most genes in one species have near counterparts in other species, anyway. Genes are almost never invented by large, long-generation time organisms like beans and cows--we all inherited them from short-generation ancestors like bacteria and viruses, so there is a lot of commonality in the genetic heritage of all creatures. There is no reason to expect that a gene derived from a different species by modern techniques will be more "alien" or unnatural in its effects than one that arises through mutation or that crosses species lines by natural mechanisms such as hybridization or viral infection. Modern genetic engineering has yet to come up with anything as bizarre and unnatural as a banana or an ear of corn. Or any food as dangerously allergenic as a peanut.
