    Yes. Assuming he meant (bits/sec) = (bytes/(sec * 8)).

    Um, no. It is (bits/sec) = (bytes/sec)*8. You got the second part right: 1 byte/sec = 8 bits/sec. But that's the conversion factor, not the conversion equation. Here's some ways to think about it:

    1. Convert the units:
    bits/sec = (bits/byte)*(bytes/sec) = 8*(bytes/sec).
    Notice that the units properly cancel.

    2. As a numberical example, if I'm getting 1 byte/sec, I'm getting 8 bits/sec (as you say). So, I have to take 1 byte/sec and multiply it by 8 to get the number of bits/sec, i.e., (bits/sec) = 8*(bytes/sec).

    3. Think about it. The number of bits/sec has to be the bigger number because there's a lot more of them than bytes traveling per second. (Eight times as many, to be exact, ignoring the extra "administrative" bits.) In your equation you divide the number of bytes/sec by 8 thus making it smaller not larger.

    Actually, this is an interesting problem, and seems possible. Take the example of two points on a balloon surface. They also follow this "Hubble" equation. To see this imagine three colinear points on the surface (P0, P1, P2) such that P0 and P1 are 10mm apart and P1 and P2 are 10mm apart. Since they are colinear, P0 and P2 are 20mm apart (following the curvature of the surface).

    Now blow the balloon up a little more such that P0 and P1 are 1mm further apart, and thus P1 and P2 are also 1mm further apart (P0 and P2 are 2mm further apart). Then (D=distance, dD=change in distance):

    dD01/D01 = 1mm/10mm=0.1
    dD12/D12 = 1mm/10mm=0.1
    dD02/D02 = 2mm/20mm=0.1

    i.e., dD/D = constant. Since the dD occured over the same time for the two distances, you can also write this as

    (dD/dt)/D = V/D = constant = K
    (This is the Hubble equation, where K=H.)

    So, in theory, you could blow up a balloon such that two points are moving faster than c relative to each other (V=c=D*K). Let's see how to do this. The distance between any two points on the surface is D = r*Q (r=balloon radius, Q = angle between the points in radians which stays constant as the balloon expands). The change in distance over time is

    dD/dt = V = dr/dt*Q.

    The furthest two points can get apart is Q=pi (opposite points on the balloon), hence the fastest relative velocity will be between these points. Let V = c and solve:

    dr/dt = V/Q = c/pi

    In other words, if the radius of the balloon was expanding at a rate of just under 1/3 the speed of light, two points on the balloon would be moving relative to each other at the speed of light. (This would not only take a lot of air, but the rate of air required would go up with the cube of the radius, so you'd want to do this when the radius is very small.)

    Applying this 2D analogy to the 3D universe, it doesn't have to be expanding at the speed of light for two distant points to be moving greater than c relative to each other. But it does have to be expanding above a certain rate to achieve this. If it's expanding slower than this critical rate, no two points can be moving faster than light relative to each other. If it's expanding faster, they can. Since the expansion seems to be accelerating, it seems inevitable that it will happen at some point if it hasn't already.

    We should also be able to figure out if it has already happened or when it will. We know the constant H (from the Hubble equation H = V/D). (It's easy to calculate anyway, given the distance to any star and it's measured relative velocity.) If we know the history of the expansion rate we know how big the universe is, i.e., this furthest distance Dmax between any two points. We can then solve the Hubble equation V = H*Dmax and see if it is less than or greater than c.

    By the way, I don't think this violates relativity, it doesn't say anything about the rate of expansion of the universe. I think this falls into the "warp" concept of traveling faster than the speed of light, i.e., if you can locally expand the universe fast enough, it appears you are moving away faster than the speed of light, and vice-versa if you can contract it fast enough locally it appears that you are approaching faster than the speed of light. I could be wrong about that though.

    The whole problem here is the concept of people who've done nothing wrong being held responsible for the criminal actions of other people.

    No, not responsible for their actions, responsible for creating the circumstances which allowed them to commit the crime. It's called criminal negligence: "recklessly acting without reasonable caution and putting another person at risk of injury or death (or failing to do something with the same consequences)"

    In other words, you have a certain responsibility to ensure reasonable safety when you are in control of property that can forseeably cause harm, such as a loaded gun or an open pool.

    The point is the reasonableness. Leaving a loaded gun lying around a house is not reasonably responsible because people do have visitors and do get burglarized. Stating that burglary is illegal isn't an excuse to not knowing that people do get burglarized. In other words, it is forseeable. Same with kids falling in an open pool and drowning.

    This doesn't carry to things such as knives for several reasons: they are far more difficult to accidently harm someone, they are very commonly used around the house and require easy access, and they are so commonly available that a criminal could have gotten one, or any sharp object, anywhere legally. In other words, it wouldn't be reasonable to expect people to lock up their knives.

    As for an open network connection, that would probably fall into the forseeable category. If you knew you left it open and you are aware that people hack into these things to do illegal activeity, it is forseeable that it could be used for illegal activity. You might not get charged with commiting the actual illegal activity if you can demonstrate that it probably was someone else, but you probably could still be charged with negligence. (Keeping in mind IANAL.) If you accidently left the network open or didn't know about network security, you might not get charged.

    This all sounds like an arguement about whether the Waterfall approach (Requirements->Design->Code>Test&Validat e) is better than the Rational Unified Process (iterative) or similar. I'm not a coder, but I think each one has their place.

    In my experience, RUP seems far better. The customer rarely knows exactly what they want. At best they'll have an idea of what they want it to do and can visualize how they think it might work. So you start with a loose set of requirements, do some quick high-level design, and code it. Then show the customer what you've got. They can identify what is different from what they want and see some of the issues they may not have thought about. This defines some lower level requirements and designs. Repeat this process on a regular basis and you will get good, well-written, and efficiently created software.

    I've had nightmares with the Waterfall process. I've had to spend 6 months writing requirements and design docs, formally releasing them, then have 2 weeks left to write the code so the software wasn't nearly as good as it should have (or could have) been. In the end, the requirements and design had some inconsistencies that could not be foreseen until you try to code them.

    On another project (that I was not involved in) all of the money went into the requirements and design process and the end software was crap, wasn't user friendly, and didn't get used. But it did meet the requirements.

    The problem with writing requirements completely before coding is that you have to basically do the design and coding in your head as you write the requirements, otherwise you can end up with things that are inconsistent. Written language doesn't have to be self-consistent, software does.

    On the otherhand, writing software without following any guidance from the customer is definitely worse.

Peer review is both a judgement in quality as to whether it is worthy to be published, and also performs "editor" and "critic" functions.
