  1. Re:500 parts per million? on NASA Probes Shuttle Oxygen Leak · · Score: 2, Interesting

    That's a good question. The inside of the rear cabin is vented shortly after lift-off, so it's not as if they expected to find none, they just found more than they expected. This indicates a leak or an instrumentation issue (one of the leak detection bottles failed to function at all), but keep in mind the SSME's have a pretty decent history of leaking from all sorts of places to the point of early engine shutdown (STS-93).

    It sounds to me like NASA is trying to kill off the shuttle... even the most esoteric engineering problems make headlines these days.

  2. Re:The great red planet??? on China Overtakes US as Supplier of IT Goods · · Score: 1

    Aside from conspiracy theories, the difference here is that stuff made in China is half the price of the other thing on the shelf, and Joe Walmart doesn't give a damn about his buddy's job if he can save that kind of money on his new Popeil Chicken Roaster. This isn't about a 10% savings for inferior goods.

    At the end of the day, making the same old computer here in the US shouldn't be interesting to us. There's not much money in it, even if your company does it exceptionally well. Literally anyone can do it, and doing it outside of the US means little or no environmental compliance.

    Now, as the US loses its ability to come up with the new stuff that can be made first here during the most profitable portion of a product's life, that's scary. Eventually, this means that the products will be invented in China, and the only stuff we'll be making is the low profit old-news products of yester-year because anyone can make it. If that much.

  3. Re:Completely backwards on Digital Music Stock Market? · · Score: 1

    The very fact that music isn't free (or close to it) should suggest that there is something flawed with the thought that there is an infinite supply of it.

    Songs aren't durable, eventually even the most catchy tune becomes uninteresting to its purchaser with time. As long as the purchaser is alive they seem to demand more songs on a varying expiration interval.

    The flip side of this is that there aren't an infinite number of songs, and a given consumer is only interested in a subset of the finite songs available. If they want more music, they have to choose from this finite set. Further, given cultural tastes, the culture expires songs from the set of all songs on a regular basis.

    So it is completely irrelevant that you can copy a song infinitely, there are only a finite number of unique songs available that anyone is interested in.

    You want a copy of my popular song? I'm going to charge as much as I possibly can for it. As the exclusivity of a product increases, the cost of producing it has less and less impact with its cost. Because we've artificially said that the owner of the copyright has sole exclusive rights to produce it, songs are highly exclusive to their owner.

    Notice that if people didn't prefer one song over another, this "monopoly" over the ownership of a song would not matter, and the cost to produce would enter into pricing.

    Water isn't worth much right now, but if I had the only water in the country -- even if it were an infinite amount of it -- I'd be a billionaire.

    When representing the outside world, it seems clear to me that you'd need a way to represent something being logically consistent as missing, unknown, or unknowable. My height is 6 foot, my gender is male, my last gynecological visit is NULL.

    The argument is, perhaps that field should be normalized into a separate table of visit dates which does not contain an entry for me. That is the true NULL, that it isn't even present in the database.

    I think it's more design philosophy than an issue of right/wrong. There are many complex problems that NULL solves quite handily by being able to represent that a relationship is impossible.

    If you've ever tried to do business with anyone from outside of the US, and maybe Europe, I think you'll find that it is a major disparity between how well businesses run between the two regions. Business Science may be the last science that the US has an advantage on, because it sure isn't the rest of them.

    Other countries can compete for now on the basis of lower labor costs, and lower cost of environmental and other compliance. You can afford alot of waste and mismanagement in that stage, but when you're industrialized and you have an OSHA, and an EPA, and your labor unions are knocking at the door, suddenly you can't throw out a day's worth of bad production because that amounts to your profit. Other countries have gone from economic powerhouses that were going to own the US, to total stagnation in the span of months.

    I'm not advocating anyone becoming a specialist in the science of business as an answer to this... the true answer is that your profession has to be competitive. And being a Scientist in the US is not competitive.

  7. Re:::Sigh: Learn a bit about economics... on Free 3D Animation DAZ|Studio 1.0 Released · · Score: 2, Interesting

    The laws of business aren't muddied with subjectiveness. Whether or not you will be better off giving something away for free will ultimately be determined by if you increased your well-being or lost the time and money (aka opportunity) invested. There is nothing subjective about the end-game.

    That's not to say that it is always stupid to give something away. People have been giving things away in exchange for an opportunity since the beginning of economic time.

    So, still within the framework of the laws of business, the question is what opportunity is created for those involved in free software. If the opportunity created is greater than that foregone, there will be free software. Whether or not it is competitive with commercially created software is an entirely different matter.

    Because of the marginal and highly eventual return on the investment of free software it is a hobby or a side bet for those involved (whether the bet is being made by the individual not being paid, or a company who pays programmers but does not charge).

    Now, if someone can demonstrate to all of us rational players know you can make a fortune giving away software, the tide may turn as we weigh the opportunity of going into commercial software versus free software, combined with needing to eat.

    All still within the confines of the laws of business that you so much hate. Good luck making that fortune.

    Definitely truth in all of that, I would add some additional points though, that are solid and real.

    Alot of the purpose of certification/degrees/training is to ensure two things: consistent process, and consistent vocabulary. Many people can be self-taught and be very good at things, but use completely different depths to the steps they use for common procedures, and use different nomenclature for everything. This goes to the point of not knowing how to pronounce words common in the industry!

    Also, people who have gone through the certification road of misery have done it with a group of people they could compare notes with, see different environments, take good ideas from them, and build a network that extends out to others that might have hiring, consultive, and other value.

    Finally, they aren't trivial to get, and if one jumps through the hoops to do it it shows a certain professional commitment and commitment to the craft. Ie, that you aren't going to change your mind on your career in a few months, and that you are focused on improving your capabilities.

  9. Re:Totally wrong on Ambiguity Drives Google's Valuation · · Score: 1

    If the cash flows were reasonably consistent an NPV works just fine, the trouble is everyone thinks there is a mountain of money in the future that may or may not be there. Taking the mean is worthless... to your point, Google will either be a the basis of the global economy or a nobody in 10 years, it won't be the average of the cases unless it's heading up or down between them (at which point the game is over to buy it anyways).

    So the valuation is a sort of mathematical expectation where the payout is huge and the probability is low. Lottery tickets are no bargain, everyone knows that you will lose money... but every day a handful of people walk away with huge returns. The same force is in effect here, risk is actually counter-intuitively expensive (unlike what a discount rate would imply). People are bidding up the limited number of lottery tickets based on their collective anticipation of the probabilities of winning versus the pain of losing.

    For me, the price tag for each ticket is irrelevant. If you have ten tickets or twenty tickets in the Google lottery doesn't change the odds at all. It's all a question of if the amount you're investing is painful to lose, because you probably will.

    I respect your inclusion of evolution into what you consider for your structure of understanding. And the recognition that as a theory that describes progression it doesn't describe origin (although coming from a book with the word in the title, interestingly).

    The causality chain that ultimately put people here is a long complicated one by anyone's estimate. And where "god" sits in that chain has been influenced by our understanding of the world and how far back it pushes the necessity of "god" on the basis of things like irreducibility. Perhaps God is at the beginning of the causality chain. It doesn't seem as if science will ever be able to put anything at the start of it in any case.

    But even if God exists, what created God? Whether God is at the start of our causality chain or nor is the smaller question compared to what is at the start causality chain for the universe that God (or whatever created our universe) exists within.

    Then again, something eventually has to break the rule that it must be contained within something larger than itself. I hope. Maybe God knows that answer? Something tells me He is as stumped as we are. Fortunately our "virual" creations haven't become aware of their own existance so they can't join in on the fun. Yet.

The last few good people worked really hard but couldn't document a single thing in the pressure to release systems.

    As for the updates and how that works, etc, the XA/21 system uses RTU's in the field which are basically 1200 baud modems with some instrumentation and a simple controller. They call back into the main system every interval and update their status. From what I've read, however, the trouble was that the master server set had failed, and the secondary didn't switch over correctly.

    I saw this happen when my company evaluated a $2 million package by Big Software Company X and went away saying no way in hell. Then it came down from above to look into it, and $4 million and 2 years later it's still not done. The problem is, any project with that much money, and the big names on it can't (by definition) fail. So more money, more time, more frustration.
