  1. Re:Bionic eye on Hacking a Pacemaker · · Score: 1

    Look up public private key cryptography and get back to me. Asymmetric cryptography does not require revealing the private key to hospitals....

    I think the GPs terminology is wrong, but he/she is hinting at a potential problem. The single-instance-public-private-keypair in this scenario is as follows:
    Pacemakers gets private key
    Every hospital gets public key

    Public key is used to encrypt data destined for the pacemaker. However, if the public key is released more widely than just the hospitals, a bad guy can do bad stuff by encrypting bogus pacemaker commands with the public key, which the pacemaker will assume are legitimate.

    One way of securing this is to have a PKI. Hospitals would get signing keys authorized by the pacemaker manufacturer (or perhaps a pacemaker consortium would start a CA), and the hospital could sign and encrypt a message for the pacemaker with a key issued by a trusted node in the chain. Signing is always good :). A PKI is worse in some respects, though: If the root cert of the PKI were compromised, the certs would have to be revoked and new ones issued. This would require removal of everyone's pacemaker.

I implemented prior art, as I used to have an account on a unix box with my ISP. I would log in to a shell, and download MIDI and MIK/MOD files from various FTP servers into my Shell account (the 'data aggregator' from their patent). I used 'sz' (Send via Z-modem), an old shell tool, to copy the files from my ISP server to my local laptop (56k connection [actually a bit slower back then, but who's counting]). I would then listen to the music when I rode the bus. I even plugged my laptop's sound output into a cassette adapter and listened to that stuff when I got my first car. This was in 1996. If Apple wants prior art, I'll testify on their behalf ;-).

Astrology is utterly non-scientific, demonstrable by experiment (I used to demonstrate its non-scientificness in a class that I TA'd, by posting the day's horoscopes without the sign listed. People would guess which horoscope was theirs, and then we would analyze the results of their guess versus random chance. Random chance was generally as accurate as the prediction with sufficient sample size). If Eugenics proponents like William Shockley are to be believed, then bigotted groups like the KKK actually have more of a factual and scientific basis than astrology.

    Hate to break it to you, but there are a ton of connections between classified networks and the Internet. The connections are generally made via high assurance gateway devices (usually a few systems that work together to protect the connection). Wikipedia has a general article here. There are some of these things actually in use, and their use is a lot wider than you would expect.

    In my previous life, I worked for the DoD's head of cross-domain solutions as a research weenie and pen-tester. I'm quite the skeptic about the way the cross-domain world is run: the solutions are all based on super-old and kludgey software, and DoD has been too terrified of risk to admit that it needs to come up with higher-assurance solutions.

    Also, there's too much data on DoD's networks to be accurately classified these days. Classification levels are supposed to determine how detrimental a leak would be to national security, but typically a few unclassified documents are assembled into one place and the result is classified. It's also worth noting that in an ideal case, only unclassified material will be on the unclassified network, but security violations happen all the time. At one of my previous employs, a contractor was caught taking a USB hard drive home (as in, to his house) from a classified lab. He got a slap on the wrist. Later, he got a job working for Defense Intelligence. I can only presume that his clearance was not affected.

    I was a big proponent of "disinformation" while I was a research weenie: seeding bogus reports, making up totally insane presentations for research projects that weren't real, etc. I think it's a good area for DoD to invest in the idea, as in creating a 'disinformation czar' (or preferably one or two of them per research lab).

Music and movies don't and won't come with the same kind of implicit permission.

    The "half of it being on websites that were not the express permission" thing is a whole 'nother can of worms. If you see people using your copyright-protected photos/text and transmitting those photos/text from their own websites, you have every right to sue (at least in the US). The trick is that you generally have to show financial harm, which can be a lot harder to do. If your photo and text are available free-of-charge, it will be especially hard for you to show financial harm. If, however, you run a members-only pay site, you would probably win. Similarly, movie companies and music companies charge for their product, so it fairly easy for them to show financial harm.

The US has 300M people roughly, and has 100k fewer square kilometers than Canada with its 30M people.

Another might be some measure of national 'inventiveness' like number of patents, research papers published. Another metric might be life expectancy. Yet another could be a survey asking citizens how happy they are.

Germany's tax base is quite a bit higher than that in the US. Perhaps the legend of the cowboys are to blame in driving people to the streets?

    I believe that there is a misunderstanding of my argument here. I am claiming exactly what you are saying in your first two sentences. The government creates monetary flow. At the end of the fiscal year, every government agency must have $0 in its coffers. In this, we agree. Where our opinions diverge is in whether this government intervention in an economy reduces efficiency. I believe that it is a great academic argument to make a claim one way or the other. But show me an economy where the central government takes no money for redistribution, and I'll show you a country that does not exist. Every government has to take some money from its economy, or it simply is not a government.

    I believe that, in many cases, the central government doing this creates market efficiencies (e.g. creating improved markets and new markets where none existed before). Look at the Internet for a great example. Without direct government intervention, the internet simply would not exist as a tool, and I would argue that without this tool, our economies would move far more slowly than they do today. Also look at the space program -- as a strictly free-market venture, companies would have given up on the idea of putting satellites into orbit because (initially) the risk was just too high. Now we have cheap satellite imagery, which has made economies far more efficient (crop production, mining, and even wars are made more efficient in both money and cost in human lives), as well as other fun satellite tech to help us in the future. When initial risk is too high, the basic research foundations for a market will never come about. This kind of risk is okay for a government, though, since it has no competition to worry about.

    I'm sure there are both positive and negative cases for both sides of this argument, though. Governments waste a lot money (slowing down the economy) through failed research/fraud/whatever a lot, just as they help (creating new markets) through research that is simply not feasible by a free market due to risk a lot. I place myself in the camp that we have to accept failure sometimes in experiment, as failure teaches us. In the end, I feel that humanity will not advance as quickly, or at all, in a strictly free market. We need the occasional government-sized initiative to make scientific discovery. Yes, it is possible that discoveries such as those I cited would have come about with government intervention, but to me it seems rather unlikely...
