  1. Re:Science made lasers. Good enough for me. on U.S. Classrooms Torn Between Science and Religion · · Score: 1

    You completely missed my point. Take geometry, for instance. Mathematics is a kind of 'pure' science, since we don't have to worry about philosophical problems like the limits or nature of observability-- we don't actually observe anything. But we still need to accept some basic facts, like the idea of a point. Try to prove that a point has one dimension. You can't. This is because we define this thing called a 'point' to be a thing that has one dimension. In fact, if we try to be more specific with our definition, we find that our understanding of the thing becomes less and less precise. Therefore, our understanding of a point is axiomatic, and we simply must accept it. Euclid attempted to compile a list of all the axioms of geometry, and many of them are still important tools in a modern mathematician's toolset.

    Science has a few axioms. One central belief of science you mentioned is that valid theory must be observable and testable. Why? We know, a priori, that science can't prove that anything is true, since all empirical evidence is, by definition a posteriori, and unable to prove anything. There are an infinite number (or at least a finite number so large as to be practically infinite) of testable alternatives to your theory. So why bother? Well, science posits that, with evidence, we can approximate the truth. As far as I am aware, this assertion is untestable, and yet it is a central tenet of science. This is essentially science's dogma.

    But as I mentioned before, these kinds of beliefs are OK in my book, since, like with the mathematician's acceptance of the idea of the point, these beliefs make the process of science possible. Logic requires that there be some premise to go on in order to function. Where do you start? You have to accept something, somewhere, without proof.

    Your blanket disregard for my statement was simply illogical. I hope you don't plan on getting very far in science, since the scientific method has a rather deep dependence on, er... logic.

  2. Science made lasers. Good enough for me. on U.S. Classrooms Torn Between Science and Religion · · Score: 1

    No, OP is correct. Science is a system of belief. You believe in certain axioms, which are unproveable by definition. You accept them because it makes the conversation possible. For instance, in order to believe in science, you need to have faith that there is such a thing as 'rationality'-- namely, that the world is intelligible, logically consistent, and so on. It's conceivable that our universe is unintelligible to us. Science may not explicitly reject this idea, but it certainly does so implicitly.

    I personally believe that accepting rationality as an axiom is an easy compromise between unhealthy skepticism and full-out acceptance of religious doctrine, because "skepticism" doesn't even make sense without "rationality" (you can't say that an argument is 'invalid' unless you can say that the argument is 'irrational'). The difference between science and something like Christianity is that science has a built-in mechanism for self-correction. It may not work quickly, or perfectly, but you can be damn sure that over time, scientific theory will better fit the facts. This is not possible for a system of belief that relies on doctrine.

    I don't see any problems with accepting that science is a system of belief, because as a former student of philosophy, I know the kinds of problems you can run into when you start throwing everything out. Read some Kant or Descartes and you'll see what I mean. Quagmire. My cavalier attitude gives certain anally-retentive people an icky feeling.

    Besides, science brought us lasers. Think about that. When did Jesus last bring us lasers?

    Good alternatives to password authentication have been around in the UNIX world for a long time. You can use certificates, keys, one-time-passwords, and so on. Since no one is trying to lock you in to a particular solution, you can often mix and match them to suit your particular needs.

    I've been using ssh keys quite successfully, and we're currently implementing a VPN setup using authpf. We're using ssh keys + passwords for this. If a machine is stolen; it's not a big deal. The theif has the key but not the password. Passwords are useless unless you have the key. So authentication is essentially tied to a machine and a user in this case. It's not foolproof, but it works well enough for our needs.

    You might want to consider running your Windows apps within a virtualization environment, so that you can take advantage of some of the existing authentication solutions out there for other host OSes.

  11. What about other kinds of filtering? on Has Verizon Forfeited Common Carrier Status? · · Score: 1

    The whole common carrier thing is more complicated than this. Of course, I agree that Verizon should not have dropped these people even though most of us find the site's content to be questionable, if not offensive. But there are lots of kinds of traffic that an ISP needs to filter, and they have been traditionally reluctant to do so.

    For example, DOS attacks. You could argue that DOS attacks prevent the system from working correctly, and so they must be blocked by th ISP to ensure proper functionality. And I think that most network engineers would agree with you. But see, here, we're starting down the slope a little-- when we say a common carrier does not block any traffic, we don't really mean "any" traffic. It just blocks the really bad stuff. In any case, we could probably make a strong argument that blocking this stuff doesn't violate their common carrier status. Same thing goes for DNS cache poisoners, BGP manipulators, and so on.

    OK, now what about RPC worms? Certainly, they make make Help Desk techs unhappy, and probably a fair number of sysadmins as well, but is it breaking the system? Not at all-- the Internet is working fine, delivering those RPC buffer overflow attacks to their unsuspecting victims, turning their machines into botnets and whatnot. But a lot of people have been pushing for ISPs to do something about this-- certainly, I have contacted a number of ISP abuse departments myself. So here's another class of traffic that we want the ISPs to deal with-- filter-- before it even gets to us. Does this violate their common carrier status? I don't know-- it's in a grey area.

    Here's another one-- SPAM. SPEWS is a great example of a DNSRBL whose sole existence is to place pressure on ISPs to drop abusive customers. Actually doing so certainly technically violates the idea of a common carrier, even if it doesn't violate the spirit, unless you really consider SPAM to be a valuable bit of Internet communication. Some spammers might, I guess. But I think there's probably nearly universal support for ISPs to drop the really awful spammers.

    The point of all this is that common carrier status is not so cut-and-dry. Where do we draw the line? There's also the question of a company's right not to do business with someone. If an ISP decides not to accept the business of a questionable website, is this filtering/censorship, or just a good business decision? I don't think this is at all clear.

    A guy who used to work for me described it this way: people want a computing appliance.

    You're right, of course, but the problem is that computers are not appliances. Appliances are anathema to the whole idea of general-purpose computers, which are supposed to be flexible. You have to have some training to know how to frame a problem in a way that a computer can solve it for you. Bad interfaces aside, I find that many people who run into issues with computers do so because computers are so extremely literal. Most people simply cannot, or refuse to, wrap their minds around a computational task. So yeah, people are stupid and/or lazy. I think the GP is spot-on.

    That said, the UNIX philosophy deals with these kinds of problems in an elegant way. You learn small, flexible tools one piece at a time. 'cat' is as useful to a guru as it is to a newbie. I learn new things about 'egrep' every day, and egrep only does one basic task. And with those two tools-- and some other simple ones-- I run circles around the inflexible software designed for the boneheaded network engineers I work with. People who are too lazy to do it right the first time, and empty their pockets looking for an easy solution. Learn the fucking tools, guys! Using your BRAIN is the easy way.

    Toasters and cars have rigidly-defined roles. Toasters toast and cars drive (although a previous vehicle of mine toasted as well... long story). The simplest "role" I can think of for a computer is that of a "thinking machine". You need to THINK to use it-- it's a tool for thinking! With some ingenuity, people can make computers that run toaster and cars. That's powerful!

    I don't really give a shit if people don't want to use UNIX. I'm happy using it myself. GNOME and KDE help lessen the learning curve for people who are used to GUIs, but if someone wants to learn how to use a real computer, they're going to have to get dirty. "bit twiddling" is how you get dirty.

    Dell's stuff is OK. Their main selling point is management software that comes bundled with the hardware. It's true-- if you want a simple 1U with integrated GbE, PERC RAID controller, and so on, you can't get much cheaper than a Dell machine.

    IF, that is, you actually want to use Dell's software. We'd been running OpenBSD for years on Dell hardware, and then Dell threw us for a loop and started substituting in integrated Adaptec controllers to replace the AMI ones for RAID-- without notice. This was around the time when OpenBSD was threatening to remove the Adaptec drivers from the tree. So for awhile, we bought AMI PCI-E cards to replace the Adaptecs, and that worked fine, but then I did the math... and I realized that Dell's value was in the software, which we weren't using at all.

    For a lot cheaper, I can put together a 3U machine from "commodity" parts-- all the parts can be bought off the shelf except for the chassis and PSU (which I get from SuperMicro). All of the parts are exactly what I want, well-supported in OpenBSD, and replaceable. The last point is a major consideration for us. What do you do when an integrated controller goes bad in a Dell machine? If it's under warranty, you call and get it replaced. That can take days (although to Dell's credit, you can get it much faster if you pay for a more expensive service plan). With commodity parts, all of your servers have the same basic configuration-- you keep extra parts on the shelf (even the mobo and chassis), and you still save. The big savings comes from not having to pay $1-2k/yr per machine for a support contract.

    The eureka moment came to me while I was waiting for parts to arrive for a machine that was covered under a contract. I was thinking-- if only I had spare parts on hand this would have been fixed by now...

    Anyway, all of Dell's other stuff, consumer items, is just the same as anyone else's. It's probably good, sure, but it's probably the same (or very similar) to what you'd get from HP or whoever else builds PCs these days. In my mind, it's crazy to buy a machine like a Dell through a VAR like PC Connection when Dell is essentially a VAR themselves these days. They don't manufacture anything unique. Dell obviously cuts costs by selling directly to consumers, so their volume discount almost cancels out the assembly cost. But you could probably build the exact same machine by buying parts from NewEgg.
