    If you're applying religion to science, you can't act as if doing the reverse is wrong. Prove to me when the soul starts using science, or keep your beliefs about when in embryogenesis the soul starts to yourself.

    Exactly when did I apply religion to the argument? I said that science can't answer the question of when life begins. I'm not even talking about whether or not a collection of cells has a soul, religion doesn't really answer that either.

    My argument is from a moral perspective. It is simply that the only clear point at which things change markedly is when two zygotes combine. After that point you are splitting hairs - is a baby still 1mm in the birth canal a viable human being? How about just the head? Or go down the road of a fertilized zygote, does it become a human life at 5 cells, 10, 100, 1000?

    It seems that since there is only one clear point at which the system makes a dramatic state change, it would be better to err on the side of assuming life at that point rather than going the other way and saying that it is not life and then at some vague undefined point that I move around whenever I want, we'll call it life. I would argue the second standard is very arbitrary, while the first is quite clear and unambiguous. Oddly enough, it is the religious crowd that seems to want clear and unambiguous while the researchers want arbitrary and vague.

    Find me a population of adult stem cells that can repair a human spinal cord, without blending up the patient's brain first, and we'll talk

    Find me an embryonic stem cell that has been used in the same manner successfully and then we can have a real comparison as opposed to talking about unrealized potential. The treatment you are speaking of is this one. Note:

    These are not the same stem cells as the controversial human embryonic stem cells, which destroy the embryo when the stem cells are removed.

    As for adult stem cells only being in the brain, that's not correct. Here's the wiki article and if you are willing to search around on IPS, you'll find that some of the problems mentioned in the wiki article have already been solved. This is an area of active research around the world that is showing results, moving forward, and not mired in any debate about whether or not it is moral. It seems we should be focusing our efforts here until the research stops producing further breakthroughs.

    Since your stance is obviously flawed, I have to assume that you didn't know that adult stem cells are already as powerful as embryonic and that this entire conversation is a result of poor reportage, irresponsible politics, and illegal policies - as determined by a judge. That still leaves the misguided intolerance....oh yeah, the lawsuit was brought by researchers afraid of losing funding, not religiously motivated people.

    My question to such people is how do you know the soul is started at conception?

    The same question could be posed as how do you know it doesn't? It's as poor an argument to base opposition to a religious belief on a question that science is completely unable to answer in the first place.

    The real question that should be posed in this is, what is the possible harm done under either assumption, and which is worse? Under the assumption that life starts at conception, then the harm done is tantamount to murder, however someone else's life might be saved by doing so. Under the assumption that these are just genetic material and don't have any moral implications to their use, then obviously the medical breakthroughs would be preferable. The point is to have the discussion without falling into religious fervor or scientific elitism (which it is since science is necessarily mute on the question of when life begins)

    My personal opinion is that breakthroughs from adult stem cells have easily eclipsed the promise of embryonic stem cells Pluripotent Adult Stem Cells. We could simply avoid any moral hazards by continuing research on those since there are no objections from any side on their use.

    When you say "exploits the weaknesses of the fitness function" it sounds like you really mean "exploits the weaknesses of the game rules"

    Actually, that's exactly the type of thing a fitness function must incorporate. You can either constraint your population to only those members that encode a valid solution (i.e. one that follows all the rules), or you can encode the rules into a mathematical function that evaluates to a higher number if the solution is better.

    The problem with the former is that if solutions lie close to the constraint boundaries (which they frequently do), you will usually get a better solution if you take some of the encoding of a member that fails to meet the constraints but has a higher overall fitness. So to make this work, you either settle for a worse solution (by constraining population members) or you use a far more complex fitness function.

    Another major area of concern is how you measure success. If you use a single variable for success (e.g. number of wins), then you may end up with a solution that wins eventually but takes hours to do so. If you want to make that tighter, now you have to incorporate wins and time, which means you need to figure out which is more important to you If you extend this into n dimensions, you start having to worry about Pareto optimality and things get even more complicated.

    All that to say - it's not as easy as hitting the run button with a bunch of random binary strings.

In other words, if you wanted to get a particular result, you had to put most of your effort into the fitness function that describes the desired result. This doesn't work without said function, ergo, design is the key, not simply mashing things together. In fact, if you run a GA without a fitness function, you get a random walk, aka monkeys on a typewriter.

Why not simply make it illegal for a company to provide both infrastructure and data delivery? That ensures that there are companies who own the infrastructure (and lease it at a fair, published price), and companies who provide services (data, phone, etc.).

    Perhaps a better solution to this problem would be for the gov't to mandate that last-mile infrastructure must be leased competitively to all comers by the holders of that infrastructure. In other words, Qwest owns a lot of fiber - they should be statutorily required to allow others to use those lines at a published rate determined by Qwest. If Qwest charges high enough rates, then it would become feasible for another company to invest the capital to lay their own fiber and undercut Qwest, so there is some self-regulation on price point.

    Additionaly, ISPs should be separated from the data carriers themselves. That eliminates problems of those holding infrastructure from charging others exorbitant fees to lease it while offering services to users on their own infrastructure for significantly less.

    Admittedly, this is a quick idea that I haven't tried to flesh out, so I welcome anyone who wants to set me straight, but the best role for government is one in which it ensure a fair playing field, not one in which it puts its own team on the field along with its own refs.

Of those 200+ rules, only 2 of them were necessary in Ada if you use the spark code checker (which technically is just an automated method of enforcing rules, but even then, the subset of the language that is ruled out is about 10 rules, not 200). Unfortunately, his work is not published, so I can't post a link to it....

It does not allow things like arbitrary pointer arithmetic. Any type casts must be explicitly made, and therefore the programmer has to justify it (policy, not program issue, but very easy to find and check). It is really a very secure language in many respects. That's not to say it can't behave badly, it is just much harder to make it behave badly, and you have to really think about it to get there.
