    What matters is the isotopes which emit the radiation. This not only determines the form of radiation, but also the energy, the lifetime, and whether and where it accumulates in the human body.

  6. Re:Question on Is There a New Geek Anti-Intellectualism? · · Score: 2

    Is an intellectual somebody who has memorized a lot of information, or is it somebody who is adept at learning?

    I ask because I don't see a case of 'cool to be stupid', instead I see an evolution of how we function in a society where we've stored our knowledge in a manner that is dirt-simple to get at.

    Well, the point is that if it is not stored in your head, it's not knowledge. It's information which you can look up, and as such it is very useful, and if valuable enough, you can turn that information into knowledge. But it is a mistake to take that information as knowledge. Knowledge is available to you even if you don't explicitly search for it. If you know something, and then see something related, you may see a connection which you would not have seen otherwise, because you never would have gotten the idea to look up that information. And it's exactly those moments where you see relations between things which seemed to be unrelated which provide true insight.

    Knowledge is live information. Your brain constantly compares new information against it and looks for connections, even if you don't notice it. Indeed, even when you're sleeping, your brain is actually working on that knowledge. On the other hand, information you have to look up is dead. It does exactly nothing until you look it up. It comes to life only as you read it.

    Note that I'm not saying that this information is not useful, or that it isn't a huge advantage if you can look it up quickly. But it's much less useful than information which resides in your head. Of course, the information you can have in your head is limited, and therefore it is an advantage to easily be able to look up things. Also, there are things you might need sometimes, but which are clearly not generally relevant to you; not needing to learn those is definitively an advantage. But the idea that you could generally replace knowledge with looking up information is misguided.

  12. Re:WARNING on Integrating Capacitors Into Car Frames · · Score: 1

    To clarify, watts are not a valid measure of a charge of energy. The energy in a capacitor is it's charge, which is measured in coulombs.

    Charge is not energy. The energy in a capacitor is measured in Joules, just like any other sort of energy. Now for a capacitor, the energy stored in it is a function of its charge, which is indeed measured in Coulombs. But they are not the same (they are not even proportional, and capacitors of different capacity store different energy for the same charge).

    Well, building your computer from silicon yourself isn't enough. After all, how do you know the machines you used to fabricate your chips are not compromised? Maybe they don't produce exactly those chips which you designed? There's no way other than to build those machines yourself as well.

    Oh, and don't make the mistake to use VHDL or similar to design your chips. Your VHDL compiler may be compromised, too. Only if you understand your chip down to the wire, you can be completely sure.

    Actually, if we name the input bits i0 (LSB) to i3 (HSB) and the output bits o0 (LSB) and o1(HSB) then the calculation to do is:

    But could a malicious person write another, malicious ant which manipulates the existing ant colony for his own goals? Those malicious ants could leave false scents at completely harmless computers, or remove scents left by other ants. Maybe it could even manage to free some part of the network from ants by leading ants at its borders to other parts of the network through strategically placed scents. Indeed, it could even be a DoS attack by simply creating lots of copies of the existing ants, which then will clog the network. Say, add a few ants which do nothing but clone other ants they encounter. Let a few loose in the network. They will start to copy good ants (and occasionally other bad ants, thus slowly increasing the copy rate, while never becoming a large fraction of all ants). After some time, the ants will start to clog the network; since the vast majority is (clones of) genuine ants, it will be hard to detect the cause of this.

    Now if only Slashdot admin would get a clue about JavaScript we could get rid of the irritating "Working..." graphic permanently stuck at the bottom of each page.

    Oh yeah and when you click on a post in a message they could fix their CSS so every single click (even to cut and paste) doesn't redirect you to the top of the page.

    Do they never preview and test anything before putting it on the production servers? Sloppy and unprofessional.

    Also, it would be nice if the score of a post would be shown also if several parent posts are collapsed. And if clicking somewhere in a post with collapsed ancestors would do whatever the action is for that place (follow a link, place focus into input box, etc) instead of uncollapsing one of the ancestors.

    Or basically, make Slashdot again a site that works.
