  4. My Privacy Anecdote on Obama May Toughen Internet Privacy Rules · · Score: 5, Interesting

    So, that's nice that the government wants to crack down on sites like Facebook, but I think there are data mining things going on that most folk (even some on slashdot) are unaware of. For instance, awhile back I decided to switch my car insurance policy from company A to company B. When I contacted company B and had them quote me a rate, they said there was an at-fault accident on my record that shouldn't have been there. I asked them where they got that information because my DMV record was clean. They explained that they got their info. from a third party company that gets that kind of information from DMV. They told me I could contact the company to have the accident removed from my record, as there seemed to be no problem with the insurance company disputing the alleged incident (in other words, I am not paying for the accident). Well, I did some Googling and internet browsing and found the company. They list themselves as a data aggregation company (one that I had never heard of) that will sell information to any party interested (information like my personal driving record). There was a whole process you could go through to "opt-out" of their aggregation service, effectively limiting them from collecting information on you. I started the process which involved a few forms asking for personal information. Not wanting to give this company much more information, I just decided to call them instead.

    I talked to a customer service rep. and they helped me get though the opt-out process without giving up much more in the way of personal info. The rep. quipped, however, that my efforts were pretty futile because there were countless other companies providing the same services. So I asked for those company names and, sure enough, eventually found their web presence with similar business-descriptions and opt-out policies. All of this data aggregation was happening unbeknown to myself and probably most folk that are not in the car insurance industry. Many of them had outdated records (they only mine DMV so often), and showed various false information about my driving record in their records. This was the info. that would be used to analyze my driving habits for insurance rates. All in all, it was breathtaking how flawed and vast this info. gathering network was.

    So, long story short, the privacy thing goes a lot deeper than Facebook. Frankly, I have a Facebook profile and I couldn't give a damn about my privacy settings on there (I never want to work for someone that takes things I say on a site like Facebook seriously). What I do give a damn about is companies that turn a profit off of data-mining me without my permission (I NEVER requested any of these company's services, why the hell do they have the right to gather a profile on me?)

    Anyways, I would much prefer to see legislation regarding issues like mine rather than crap directed at Facebook or Google. Either way, it was a few months back that I went through all of this and I forget the name of the first company I contacted. I think I still have it written on a post-it note at home. I'll try to find it and dig it up to post in a response to this message later.

    This might be a bit of a flame-bating stretch but I'll take a shot at it. The JWST will be able to see as far back to a few moments (on a cosmic scale) just after the big bang. The amount of evidence (and pretty pictures) gathered regarding the origin of the universe stemming from a single, brilliant explosion will increase (and NASA will publicize it, they have a great PR program). Each bit of evidence ingested by young minds that are being raised in creationist households (or just generally uneducated households) will contribute to that young mind wanting to learn more about our origin and the wonders of the universe. It probably will even go on to inspire a few more kids to study science, math, and other such fields. This will produce a few more college graduates, a few more rational beings, and a few less emotion driven doofuses. It might even go on to squelch some of the more outspoken religious nutjobs once and for all.

    Fast forward some years and those minds are now voting on important issues, like hunger, the poor, disease, etc. When they vote, since they are a bit more educated, they will vote a little less passionately and more reasonably. Those minds will now vote for funding to go to projects like the JWST, rather than killing "them damn Muslims!" over a religious pissing match. When they look for jobs, they will find jobs in the sciences. Jobs that may continue to help the fight against disease, or hunger, etc. And little by little the big social problems that you list will get chipped away at with successive generations of students (and even grown adults being exposed to evidence for the Big Bang for the first time) growing more intelligent.

    Projects like the JWST and other scientific undertakings combat the problems you list indirectly through attrition. Public education regarding, and access to, scientific knowledge helps battle social problems through a war of attrition. The reality is that the problems you listed are symptomatic of society's attitude, not it's technology. We can produce enough food to feed everyone. We have enough smart people to educate everyone. We choose, as a society, not to do such things because we do not value them as much as other distractions presently. Every project like the JWST helps to shift those social values a little further away from emotional and sensual satiation towards scientific progress and the development of the human species.

    In other words, your list of problems cannot be solved by technology (or, more appropriately, they already have been). They must be solved by social attitude. Projects like the JWST help shift that social attitude in the right direction over time.

    ' However in this case, I'd imagine the logic is more like 'hey you're pulling really hard on the arm right now, and there is a lot of resistance, meaning the guy needs more help, so pull harder!'

    That's not really how control programs tend to work in applications like these. Generally speaking (and I do mean very generally) in some sort of advanced control system you have a set of commanded states that you want to achieve (force, acceleration, velocity, whatever). This command set gets fed into what is known as a plant which is a complicated set of matrices that models the dynamics the system being controlled (so maybe this would exist for each joint motor, or something like that). The plant calculates, based on a set of inputs, a probable outcome of states (it won't be exactly the same as the commanded because of system loss and unmodeled dynamics and such). These output states are then fed through some other sort of control block (maybe a simple gain, maybe a state-estimator, it depends on the application) and circulated back to the input of the plant. They are combined with the commanded states via a negative combination (you take the difference between the two states, commanded and output from the last cycle) and used again to produce another set of state outputs. This cycle continues many times a second allowing the system to "damp" perturbations and disturbances in the state variables, thus achieving a highly accurate approximation of the commanded state in a short amount of time.

    The feedback, therefore, is primarily used to ensure the commanded state is achieved correctly.

    The danger you are speaking of generally gets handled through the commanded rates logic. If, say, you need to lift a 50 lb box, then you need to apply 50.1 lbs of force to accelerate it upwards. You need a set of controller code in order to determine this commanded load of 50.1 lbs. In order to do that, you are going to be reading multiple sensor signals and developing your state commands. These sensors will include a set of pressure, temperature, and maybe even moisture sensors in contact with the human operator. The reason for this is that the commanded rates will be calculated based on the load being exerted against the suit by the human being. Based on the sensory inputs, a set of command states will be generated and fed to the actuator controller that I described above. As such, the system already has access to data regarding the load existing between the human operator and the suit. The safety issues you worry about, therefore, are relatively trivial to negate via the logic that computes the commanded states. Essentially, since the controller will be processing data regarding human-suit loads, it can involve some simple checks such as:

    "if ( $human-suit_load >= ($Survivable_Human_Load - $Some_Safety_Factor) ){$human-suit_load = $Maximum_Allowable_Load}"

    Of course, this is a very simplified model, but the point is that the safety check actually gets handled while setting the commanded loads. Thus, the actuators won't even be able to see a value that is too high for human safety. Redundancy can be added by implementing a series of simple filters to the commanded state input to the controller plant (something like a Schmidt Trigger). Safety, therefore, gets built directly into the suit contollers to prevent the suit from exerting an excess load on the human body via the suit.

    You see, this sort of development is the precise work done by folks known as control systems engineers. They get paid, explicitly, to develop stable systems that cannot run away with unstable state variable modes. If they fail to do this, then not only will the human inside be turned to mush, but the hardware that the control logic is implemented on will exceed its own max loads and the system will fail spectacularly. So the entire purpose of this kind of engineer is to ensure this doesn't happen. Companies like Raytheon fork over millions of dollars a year to employees to do ju

This is a priceless quality in some societies where academic and scientific competency are mocked and scorned.

They offer valuable services and products to those that need them. If such products and services are, "below," an uber-geek like yourself (I have to assume you are one, to write such scornful and condescending words), well then don't use them.

We have this obsession in the States with four year degrees, acting like employees without one are incompetent and useless. We have students that don't want to attend college attending college because they are told there's no other way to succeed in the world.

Throughout nearly every episode we have Samantha Carter doing her best to explain the physics being used in terms that can be understood by military grunts like Jack O'neil (and, consequently, the audience). They talked often about the power requirements to drive such technologies as FTL drives and stargates. They integrated astrophysics into many of the single-episode story arcs (time-dilation due to black holes, adding mass to a gas giant to cause it to combust into a star, etc. etc.). Sure, there were a few things they glossed over with things like Asgard and Ancient technology (like how the teleporters worked), but for the most part they tried to explain things using everything from quantum mechanics, to multiverse theory, and even relativity in the original SG-1.
