  1. Re: No parties listed. on NY Rejects E-Voting, DOJ Trying to Force the Issue · · Score: 1

    That's often true of city elections. Many city charters call for "non-partisan" elections for mayor and city council. Because most candidates with any hope of winning belong to a major party, the only consequence of any significance is that party affiliations don't apear on the ballot. If you're registered with any acive party, they'll be sure you know which candidates they "endorse", even if they can't call them official party candidates. It sounds silly, I know, but that's the way things are done in many municipal elections. With electronic voting machines, it doesn't even have the environmental benefit of saving a few quarts of printer's ink!

  2. Re:Times have changed. on Does Hacking Grades Warrant 20 Years in Jail? · · Score: 1

    Times have changed. Once upon a time, the university ran their own grading system on their own computers. They might be inclined to say "nerds do things like that", and quietly change the grades back to what you earned. But a third party has a financial interest in their reputation for due diligence and security, so they will take things more seriously and call in the DA if they find evidence of anything suspicious. Notice the article said they were caught by a routine audit for accuracy of the data transfer to Peoplesoft's system: how does an overburdened university's IT department do that? This is the best kind of press: take over a university's grade records, find a cheater, and turn them in to the proper authorities. If you're the university Chancellor, that's a company you'll want to retain!

    The article cites companies saying their growth market is in countries where most people have never owned a PC before, and also that existing customers see no compelling reason to upgrade. The average user is happy with the PC they have, indeed they don't even use all the system capability they already own. They prefer to spend their money on something else. In the wealthy "developed" world, a PC now is a commodity appliance rather than a trendy status symbol. It's all part of an innovation becoming a mature product.

    "A geosynchronous orbit stays above the equator, hovering over a particular spot on the Earth's surface. As such, it will spend, on average, exactly 50% of the time in sunlight (ie. when it is sunny at the point on the Earth directly below it), and 50% of the time in darkness (ie. when the Earth is between the satellite and the sun). So, 12 hours a day."

    That would be true for LEO satellites, but not for this project. Geosynchronous orbits are many time the diameter of the earth. The orbit radius is 42165km, compared to 6363km for the earth. The eclipse zone is no more than 17.4 degrees, less than 70 minutes long. Because the earth's axis is inclined to the its solar orbit, the long eclipses occur at the equinoxes. For much of the year, a geosynchronous satellite never passes through the earth's shadow at all, remaining in full sunlight 24 hours a day.

  14. Compliance test is not multiple-choice on Microsoft Questions FCC's 'White Spaces' Decision · · Score: 2, Insightful

    Yes, that's right. If one sample meets the limit and another does not, how would the test tech know which one was truly defective? In the case of interference testing, a broken product often seems better than the working one (it's likely to have fewer or weaker signals making noise, hence lower interference measurements). The unit was tested as received, and that sample's performance determines "pass" or "fail".

    The nature of certification tests is that the test sample represents all products shipped. It's the manufacturers' responsibility to deliver working test samples. If the manufacturer didn't have anybody present to demonstrate the failing unit really was broken, the test technician not only was justified in giving a "test failure" verdict, but as an independent evaluator also was obligated to do so.

    The company should have much more to offer than just the source code. Given that the machine is to be used as evidence in court and was purchased under contract to state specifications, there should be Engineering documentation backing up its design and performance (that's capital-E Engineering, signed off by a P.E. licensed to practice in Minnesota). For example, have the device's hardware and software reliability been demonstrated to meet any industry standards for quality and reliability? There are standards for household appliances* that require such documentation for their embedded software's safety features. Evidence in criminal cases can hardly be held to less stringent quality standards than a household thermostat. That documentation should exist, and the attorney probably is trying to either get it into evidence or make the company admit it doesn't exist.

    S.O.P. and laws vary from place to place, but around here a police car or ambulance approaches the red light carefully, with siren, flashing red lights, and traffic signal control strobe running. The driver does not enter the intersection against a red light unless all other traffic has yielded to them. If that means they need to slow down or stop, they brake!. Even though the law requires all other traffic to yield to emergency vehicles with flashing lights, their driver is as much responsible for avoiding a collision as the other driver who failed to yield. Failure to yield to emergency vehicles happens often, watch the morons zip past the next time you pull to the side for a car with flashing red lights.

A cell phone transmitter at 800Mhz-2GHz is not likely to interfere with an 400Hz electro-mechanical synchro, magnetic compasses, gyroscopes, 120MHz VOR receivers, etc. Digital instruments are quite another story, and they didn't test those.

  24. Interference is not an urban legend on The Real Reasons Phones Are Kept Off Planes · · Score: 5, Interesting

    TFA says:

    Also: If real testing were done, and the nature of the problem fully understood, it would become obvious that airplanes could be designed or retrofitted with shielding and communications systems that would enable safe calling through all phases of flight. But that would cost money.

    Real testing has been done. Unintended emissions from the phone have been identified as the culprit, not a deficiency in the navigation equipment. The aircraft's receivers are doing exactly what they are supposed to, responding to signals of certain frequencies arriving at the antenna. Once the phone pollutes the spectrum with spurious signals, nothing can protect the receiver. The shielding and filtering must be applied at the problem, which is the phone. Since the competitive consumer phone market demands the lowest possible cost, once a phone meets the minimum legal requirements they won't add another dime of product cost for further interference control.

    Intereference does not occur every time, but when it does occur there has been a demonstrable cause and effect relationship. Start with this NASA case study(long pdf warning).

    In July 2003, it was reported to the Federal Aviation Administration (FAA) that a cellular phone when turned on simultaneously interfered with three different aircraft GPS receivers, causing complete signal loss. The three GPS receivers were using three separate antennas, and were installed on a small aircraft. The phone was on, however, calls were not made during the incidents and subsequent tests. [emphasis added]

    In an email message to the FAA, the company who owned the airplane reported the subsequent tests taken to prove a clear and convincing direct relationship between the phone being in ON-mode, and interference with the three onboard GPS systems. The company verified several times, in multiple flights over different days, that the interference problem could be recreated reliably in the air by having the phone turned on. The interference disappeared when the phone was turned off or covered behind a metal object, and re-appeared when turned on or brought into the open again. In addition, the company conducted tests at two different places to ensure that it was not dependent on location, and were able to reproduce the interference effects at both. The interference occurred when the plane was in the air, but not on the ground. Tests using other phones did not create interference problems on the same aircraft and systems.

    Then consider this article from Spectrum. On page 3:

    Our data and the NASA studies suggest to us that there is a clear and present danger: cellphones can render GPS instrument useless for landings. Clearly, the cause of the problem is that the FCC issues RF emission standards for consumer electronics, conferring only minimally with the FAA and with no formal consideration of the implications of those standards for the aircraft environment. For its part, the FAA relies on the airlines to initiate safety plans and, like other government agencies, defers to the FCC on questions of electromagnetic radiation.

    And from page 4:

    All in all, we found 125 entries in the ASRS [Aviation Safety Reporting System] database that reported PED interference. Of these, 77 were considered highly correlated, based on the description of observed PED use and interference occurrence.[emphasis added] The reports included cases of critical aircraft systems such as navigation and throttle settings being affected. Based on the random sample entries from 1995 to 2001, we estimate that the average number of reported interference events might be as high as 23 per year.
