  6. Re:Welcome to Government. on California PUC Calls For A Public Hearing On VoIP · · Score: 1
    :-) The analogy of "government as mafia" is apt.

    One of the most brilliant exposition on this idea is by the late economist Mancur Olson. I highly recommend the read. Amazon link

    The short summary: the separation of politics and economics is highly artificial (especially in America). The historic record shows that there is a continuum between political governance and economics which relates to the economics of political resource theft. On the far end is "Rape and Pillage" where the political tax is 100% - all is taken, literally, but by necessity "governance" must be nomadic because the "ruled populace/economic production" is destroyed utterly by "extraction". Think Ghengis Khan.

    Next is the warlord who decides to plant roots rather than roam. Hey, it's a young man's game and it's possible to extract more total tax this way. No longer can he tax at 100% however. Self-preservation requires at least survival of the means-of-production. But it need not be generous or comfortable for any but the warlord.

    Then the warlord structure transitions to a higher tax opportunity by expanding in geography. However, no one man can span that in either space or time, so lieutenants or fellow warlords/nobles need to be delegated and herititary rule must be established. This cooperation requires further reductions in individual tax collectable by the sovereign and the creation of tiered tax (lieutenants need added incentives and protections to take the risks of playing as warlord). Think Julius Caesar, Scipio, Fabius, Pompey, et al. Think middle age feudalism.

    The transitions to dictatorship/regal where graft (formerly lieutenants'/noble's percs) becomes essential to maintaining the status quo and will of the dictator. Think Magna Carta and British Empire as a pre-industrial case - Magna Carta gave democracy to nobles, but not subjects/citizens. The WWI & II with German industry or Meiji in the industrial age.

    Eventually the "graft/redistribution" becomes wide enough and diffuse enough that it becomes "democracy" where "everyone" who matters is getting some (no there is no bright-line between the two - think Slavery and Sufferage in the USA). Our dear lobbyists+contributors are precisely an evolved version of senior noble/thieves. The supreme court decision of Santa Clara County vs. Southern Pacific Railroad, which gave corporations constitutional rights as citizens, despite not having the ability/desire to fulfill the duties of citizenship, is the Magna Carta of our age, with many of the same original selfish origins of which we have not yet grown out .

    Olson also has an interesting discussion of communism which puts it in some ways into the real m of modern rape-and-pillage mixed with dictatorship.

    We in America separate politics and economics partly to retain the constitution as a sacrosanct pillar of stability. NB I prefer to keep that stability - I'm not arguing against that. Sometimes though, the separation distorts our view of reality and causes us to make very bad decisions - both of commission and omission.

  12. 2 Types of GM Food on UK Expert Panel Split on GM Food Risks · · Score: 2, Insightful
    It's important to realize that there are two kinds of GM Food: transgenic and non-transgenic. This has to do with whether genes from a completely unrelated organism have been added to the food plant or animal, or not, respectively. Unfortunately, the biotechnology industry obfuscates (intentionally?) this difference. They typically talk about non-trangenics safety but push transgenics into their policies.

    Non-transgenic GM food isn't significantly different from conventional crossbreeding and hybridization. There are several millenia of experience and natural evolutionary correction to suggest this type isn't a big deal.

    Transgenic GM food involves inserting DNA of completely unrelated (evolutionarily speaking) species into a food plant or animal. The problem is that we know surprisingly little about metabolic pathways and their dynamics. The total experience with this type of modification is less than one human generation and only dozens of animal generations.

    The standard defense is that any "badly selected" gene inserted will simply result in the quick death of the organism preventing any bad from resulting. Unfortunately 40 years ago they said something similar about the certainty and effacacy of antibiotics and bacteria. We all know now that those assurances of certainty were misplaced. The bigger system response was more complicated.

    The whole reason biologist were surprised by the low human genome count that resulted from the Human Genome Project is because they didn't understand the complexity and extra degrees of freedom that metabolic pathways provide to biological systems. So now they want us to give them anonymous (no labeling), carte blanche (no regulations) to insert alien genes and create alien enzymes and proteins in systems no biologist yet understands well enough to predict behavior of under normal operating conditions. Don't get me started about how unprepared 99% of all biologists are in mathematics to even begin comprehend high-order, nonlinear system topologies, let alone what happens when you throw a monkey wrench into one!

    There is a lot of research in this area; I'm still involved in some projects relating to metabolic pathway simulation so I know what the state of the art is right now. Moving ahead while the research is so undeveloped yet still doing transgenic GM food is like developing the atom bomb without understanding the dangers of radiation on the human body - oh yeah, that's is how we did that - but given that we are mucking with the "internals" of the system now rather than an external "application", you'd hope we'd be more careful and less arrogant.

    Biology is usually taught holistic as a holistic science. This is good because, generally it is, and because reductionism has its gaping blind spots too. However, this is often used as an excuse to shun reductionism by some in the field. The only real difference between the hard sciences and soft sciences is that the reproducibility of phenomenology has a small variance in the former giving the appearance of "hardness" and simply facilitating reductionism, but has a large variance in the latter, often addling our limited brains and requiring holistic methods instead. Mixing computational tools with biology facilitates our brains' ability to apply reductionism to a large variance phenomena. In either case, the science is equally knowable and explainable, only we mere humans may need computers to help - hardness or softness is an artifact of human cognition.

My current work environment has the wrong monitor height, no adjustable keyboard height and minimal adjustability on knee/leg height, and barely enough room for proper mousing. But I haven't had any problems in the last years. Maybe it's the elbow thing!

    - I have sometimes gotten numbness and pain (maybe 3 or 4 times) in 30 years but its been infrequent.

    - My doctor who is also a rheumatologist (joint doctor) has always told me in those cases to *never* immobilize a body part with tendonitis (the usual precursor of CTS); reduce swelling and pain with Advil (up to 800-1000mg (4-5 pills) at a time, if necessary) if pain would lead to unconscious immobilization.

    - I get massages are a biweekly basis which include deep-tissue on back, shoulders, arms and hands. My masseuse is also a physical therapist so she knows anatomy. These relieve alot of muscle tension you aren't even aware you may have (and, no, there is no "happy ending" involved ;-p).

    - At one time I had "computer eyes" and used two sets of glasses. I haven't had problems in >10 years and just use my normal glasses (I'm near-sighted).

Imagine what the margins are on PC GPIB cards, especially with the overhead and support - definitely a loss-leader. As for cables, et al., you can almost always find them cheaper. However it may not be cheaper when you consider the overhead of a typical corporate purchasing department. I know that the cost-per-PO at HP in the mid-90s started at roughly $200 for simple purchases. If the vendor was new even higher due to setup time, credit checks, reference checks, etc. This wasn't even excessive by Fortune 25 standards back then. This why companies typically start using P-card (corporate credit cards) - even with the possible lossage, it's still cheaper. Only control freaks who don't know accounting usually resist instituting them in big companies. Suddenly just throwing in a $100 cable that could be had for $30 isn't so wasteful.

If they can't provide, they didn't lead you on; they told you how to solve your problem, regardless of the immediate economic impact. In my book, that earns them brownie points for the future even if it isn't GPIB cards. I can't say the same for HP ethics now but that's another posting. That "weird feeling" is the astonishment of seeing ethical behavior!

    As a 9yr veteran of Agilent/HP T&M (now ex) I can tell you some of the reasons why they won't support Linux or, at least, offer "NoMAS" information (No Manufacturer Available Support: "accepting this information constitutes a legal contract agreeing to never request support or otherwise use any company resources regarding this information") like the old HP Corvallis used to for "insider information" about ultra popular calculators (HP41, et al).

    The number one reason is: support cost or concerns about support cost regardless of such a NoMAS. There is this admirable concept at Agilent (hell, I was heavily involved in creating the first formalized version of it, so it must be good ;-) ) once called "Intrinsic Support" which basically asks "What do we owe a customer contact who simply possesses one of our products regardless of its current support life status or whether this is the original purchaser of the product (assuming not stolen, right)?". Well, it isn't nothing. It's at least "best effort", that is, other product support issues are the priority but if nothing else is on the burner... The "Real" HP always did this anyway. It's sometimes hard to assess those support priorities though so there is a risk of "cost leakage" that can be scary.

    Unfortunately one of the side-effects of insisting on observing a more ethical customer relationship has been reduced incentive to innovate or allow customers to innovate in hard times for these kinds of cases.

    The other element in this is that the key R&D lead/influencer for these products has been enamoured with the Evil Empire for sometime and has gone completely Cult Koolaid on .NET at the expense of rationality, IMO. You might have "picked up" on this phenomena on their web site! :-p

    BTW I've had the same request rejected also, and I had the power of an entire Agilent product division pulling for my cause. Hence, we're going with NI for our product development and an NI GPIB card will be bundled with this Agilent-sold product which will be available on platforms other than Windows! This sounds paradoxical but Agilent, like HP, has product line profit & loss so product line managers are free to "do what it takes" to make their numbers even if that means using a component that competes with another division. It's actually a wise strategy overall.

    To the GPIB-hater: if you want to foot the bill for replacing the vast installed base of both HW and SW that is based on GPIB, please, write the check now (easily in the ten of billions of $) and everyone who currently slogs GPIB code will gladly switch to some other standard. Until then, this is what we've got. USB would be nice but no one is going to pay to replace equipment that is perfectly functional, fully depreciated and still generating value despite being purchased decades ago. On top of that, in most cases, it's the physics of the measurement that determine throughput and not the i/f to the computer, so GPIB ends up being perfectly acceptable on all counts but programmer comfort! That darn HP/Agilent and other vendor stuff were made with too much reliability! Some of the newer stuff has various newer i/f but for products that have a use life of 20-30 years, even USB is new and untested in the grand scheme of things - it could become a has-been i/f in a blink like Mac ADB is now.

Advertising on tv has reached a point where dispite all the data that is transmitted (20% of each hour of programming as ads) there is actually no information being transmitted any longer. That's a problem given that ads are supposed to change behavior.

    Behavior is only changed or influenced by communication if that communication contains information in a formal, Claude Shannon sense. Creating a need to buy something and inducing you to take steps to do so is a behavioral change from either what you already do or inertly doing nothing.

    The human brain is particularly tuned to filtering out non-information (or "just" data). As ad information content goes down, people simply stop seeing the message (like driving to work on auto-pilot - you remember nothing about the specifics of the drive because the stimulus becomes predictable and contains no new information).

    This is precisely what the study is showing also. Ad recall is the same because the message contains little or no information in either case so recall itself approachs random chance as information content approachs zero, and comparing PVR to non-PVR recall amounts to comparing the correlation between two independent random signals, i.e. no measureable difference because random chance predicts the same results - null hypothesis. Using PVR fast-forward only serves to turn down the jackhammer noise of zero information messages that are already being ignored. There is no information transmitted; just the physical unpleasantness of the media "wrapper" remains. This leaves individuals using PVR fast-forward with a one-sided term in the value-decision equation: noise reduction and time savings. Advertisers' messages aren't even in the equation anymore.

    Alas, high density genechip data won't being coming soon since Affy is the gatekeeper with fairly high prices. They've lowered some prices but mostly their arrays run $500-2000 a pop, one-time use. At that price you have to spend months planning their use - most experiment use an absolute minimum of about a dozen chips (statistic significance and controls).

    Between the IP protection and the high margin, non-commodity Affy business plan, microarrays won't become commodities for at least another 10-15 years. Without becoming commodities, you'll never generate the variety and quantity of data to really take biology knowledge where it is possible or needed, or create the next biotech revolution/boom. You need to make using microarrays as cheap, easy and trivial as a disposable pipette. There are no technical reasons why it couldn't, but only business and legal reasons.

  22. Social Norming on Spammers, Privacy, Anti-Spam, and Lawsuits · · Score: 3, Interesting
    I don't have a major problem with it up to the point of actually physical harm (given the vanishingly small size of the spammer "community" I still mystified that no one has taken that tact yet - perhaps the internet community is infinitely more civilized than spammers).

    Outing a spammer is simply part of re-establishing social norms. What they do is abhorrent to the majority of the internet community and they take advantage (free ride in economic terms) the social anonymity provided by the internet to do it.

    When you live in a small community, part of the "folksy niceness and safety" of small towns is due to the fact that the social network is so small that you can't act up too far outside of the social norms of the social network without immediate negative impact. For those who were part of the usenet community in the 1980s much of the academic/intellectual elan and espirit de corps was directly (exclusively?) due to this phenomena. The community was small enough that it was just one community and the social norms were quite clear (no advertising, value for ration discourse with healthy but respectful debate, mostly, etc.)

    Similarly in the big city you have the opportunity to become anonymous since there are dozens to thousands of overlapped social networks to belong and/or escape to. People in cities act (and drive) like jerks because the probability their behavior getting back to their social network is very small and even if it did with resulting negative consequences, the current social network is, worst-case, abandonable with others available even locally. Consider usenet today or any part of the Internet for that matter.

    Spamming represents an extreme in personal (virtual) space violation - akin in social intrusion to a fatal attraction stalker in some ways. Outting spammers by posting personal information is simply applying age-old social norming: if you mother, spouse, neighbor, church or other key personal social (support) network knew what you were doing, would you still do it? The fact that it makes spammers uncomfortable is direct proof that the desired social conditioning forces are kicking in. 90% of all social harmony involves forces like this.

    I'll very happy to be proven wrong. Really. :-) Having been on this planet for a while I've had an eerie ability to "see" possible paths of human and group behavior. This was part of what led to the military hiring me for "scenario planning" and "threat analysis". I certainly hope there are enough the barriers you both describe to keep us out of that path.

    Again I'd be pleased to be wrong! There are some discomforting signs though.

    HARMs are pretty smart. Shrikes aren't slouchs. Both are compable of differentiating fairly subtle differences in rf spectral signatures.

    In a past life I was one of the guys who tested these puppies (Shrikes, HARMS, Cruise Missles, Mavericks, Smart Bomb guidance systems, etc.) at China Lake NWC. For Shrikes and HARMS we would setup dozens of "threat" simulators, each with slightly different modulation (CW, PRF, PW, jitter, spread codes, etc.) to simulate particular makes and models of radar, and each at different location to simulate real life deployment. You don't want to be near any source that is on a target signal profile list. One of my other duties included measuring the distance between the boresite and the missle's impact crater after a test. Often enough my simulators were damaged or destroyed by inert warheads alone :-). Let's just say the 100-hour 1st Gulf War wasn't much of a surprise - China Lake has geography a lot like Kuwait and Iraq.

    It's certainly possible to discriminate targets well enough to avoid targetting TV satellite uplinks. It's even possible that journalist's military-supplied uplinks are provided with known spread code signals that are put on an avoid list. A warning and insistence on "equipment registration" may be CYA - unless they know the equipment's signature, there's still a small chance of a "mishap". However, unless they choose to target TV stations it would still probably be pretty safe (How many TV broadcasters does Iraq really have? Ah, maybe one? Compared to simply being shot by accident?) The spectral signatures of analog or digital TV are pretty different from radar (even spread spectrum radar).

    Despite my experience with this stuff, I'm still against this war and the facile justifications pathetically provided for it. If you don't see a patriot described above, you need to get your head examined!

    This war is about extension of the Monroe Doctrine to the entire world and Manifest Destiny as a world hyperpower. It's spelled out on the PNAC web site. Note the founders include Rumsfeld, Wolfowitz and other major hawks in the Bush Adminstration. Also note that the entire obsession with regime change and axis of evil predates 9-11 back to when Clinton was approached by PNAC with essentially the same Iraq/Axis of Evil plan. Clinton rejected it. Bush has embraced it. Linkage between Al Qaida and Iraq? Machiavelian fiction, nothing more. Weapons of Mass Destruction (worked on those too ;-| )? Doesn't add up in the context of post-War Iraqi infrastructure and economics, and especially not with forged documentery evidence provided by the US and UK intelligence agencies.

    Creating a hegemon might not even seem so bad if you happen to be an American, but this type of foreign policy is certain to be mirrored in domestic policy: the beginning is Patriot I, Patriot II, TIA, CAPP and other recent laws and proposals.

    For those who have read Linked, consider what a Bose-Einstein condensation of a geopolitical social network is in comparison to what it is for an economic social network. Consider that one of the desires of PNAC is to assure that the relationship between the US and each other country shall be stronger than the relationships between any pair of countries. What social network topology is that? Can you say: "All Roads Lead to Washington".

    There are many active and reserve duty officers with similar concerns. I recently gave a speech about this subject where an officer I know, who is now serving in the Middle East, was in attendence. I was concerned about his reaction - these are scary ideas most people would prefer to ignore - but he approached me after the speech and was my stron
