  1. Re:two voters on $1M Prize For Finding Cause of Unintended Acceleration · · Score: 1

    maybe because voting algorithms that only have two voters are total fail?

    No, it's not. In an electronic voting system with two voters, if they do not agree, you throw an error then safe the system and shut down. Two voters is enough to know you have a failure; but, not enough to continue operating.

    And you should still be able to force it into neutral. If you hold down the "Start" button, it kills the engine.

  3. Re:What's with these drive by wire cars? on $1M Prize For Finding Cause of Unintended Acceleration · · Score: 2, Insightful

    If done correctly it is not more dangerous. mechanical cables and linkages fail too. What you get out of it is greater flexibility in the design and added control that lets the designer improve efficiency. for example it is generally better to ramp the throttle open rather than snap the butterfly open -- snapping it open causes a sudden loss of vacuum in the manifold which kills airflow for a fraction of a second. You'll get better fuel economy and the engine performance will be improved. Coming in the not too distant future is electronic steering. Removing the mechanical connection to the steering wheel will make it possible to repackage the system without having to worry about shaft angles; and, will improve safety in accidents because there won't be a steering column to get in the way and crush legs.

    Drive by wire aka fly by wire is technology that's been used in aircraft for two decades now and is only just finding its way into cars.

    All modern ecm's have a rev limiter built into the software so that an engine can not destroy itself. It will rev to redline then cut the fuel and spark.

    That, in and of itself, is a design flaw.

    I agree -- I think we're on the same page. It would be weeks before everything was back to some sense of "normal". It might take months to replace all the damaged infrastructure; but, there's enough redundancy and overlap to keep most things running.

    While I agree they're blowing it all out of proportions, sensationalizing it you might say, I don't believe you understand the magnitude of the referenced geo-magnetic storms. They were orders of magnitude worse than the storm that downed the power in Canada. There will be widespread damage to substations as well as damage done to our satellite network, if such a significant event happens again. And it will.

  10. Simple solution on How Do You Get Users To Read Error Messages? · · Score: 1

    Don't produce an error message and expect the users to remember it. 1.) Write all error to log file. 2.) Keep a running log file of recent activity, so when there is an error you can see what led up to it. 3.) Present a simple messages. Worst case should be something like: "An error has occured, contact Engineering staff for support."

    I try to design my apps so that users cannot progress to the next stage unless all the required fields are filled in, correctly. I also put a colored frowny face on some error messages -- the user might remember the color, which is a clue to the cause -- however, don't rely on that. Rely on the logs.

  12. Re:Arm your citizens... on Defending Against Drones · · Score: 3, Informative

    The original article is talking about military drones. The $500 toy is a reference added by the editor. (I admit it could have some tactical survellance value, if you could launch it from nearby). While you could build a small piston engine + prop powered drone for a few thousand dollars, it would still have to be fairly big in order to carry a militarily useful payload and travel the necessary distance. Such a drone will not fly at tree top levels; and, if it did, you'd never see it before it was too late to do anything about it.

    You can't shoot a plane flying at 30,000-40,000 feet out of the sky with a rifle. For that matter, you'd be damn lucky to hit one at 5,000 feet.

    Went hiking and was caught in a downpour. It rained all night (I discovered I do NOT like being on top of a mountain during a thunderstorm). I pulled my phone from the outside pocket of my pack, it had water on the inside of the screen, between the clear plastic face and the LCD. When we got back to the car, laid it, with the battery cover off and the battery removed, on the defroster vent in my car and drove home. It's worked fine since.

    You need to look back even further. '96 was the year they instituted OBD-2 (note the '2'). My '90 Honda has at least 3 computers (one of which, the TCU, is dead). My '82 Chevy had an ECM controlling the mixture at the carburetor and the ignition timing.
