Good point. And let me add, consider the fact that hospitals can have hundreds of nurses. If the average nurse makes an error only once a decade, then 100 nurses will average 10 errors each year. Error prevention systems are a good thing.
Call me cynical, but it would never happen. Instead, oil companies would take a lesson from Hollywood, and make every single oil well its own corporation, so any disaster would be insulated to a single small corporation that goes broke.
A Chumby One, with a small touch screen, WiFi and FM radio, was $99 on pre-order, and $119.95 now, so it's not impossible, if the screen cost can be kept down. I'd suspect $150 is a more reasonable number to shoot for, though.
I did it a few times when I had my window manager configured to use ctrl+alt+(#) to switch between desktop windows. Type something on desktop 3, ctrl+alt+4 to check something on desktop 4, ctrl+alt+3 back, hit backspace with my right hand to correct my typing before fully releasing ctrl+alt with my left... boom, down goes X.
Granted, I would do something like that maybe twice a year, with 7 hour a day use, but I have done it.
Competent people turn to violence much sooner.
The Production Code enumerated three "General Principles" as follows:
Even if they only published a list of names, and omitted the SSNs, that would be an act of immense evil.
Oh yes, because a publishing a list of names of people in this country would be so evil. You know what would be even eviler than that? A list of names, with phone numbers! And maybe even addresses! They could call it a "phone book".
What the parent said. SSN should only be used as a uniquifier, to distinguish John Smith 123-45-6789 from John Smith 123-99-4321. The government should pick a date, say 5 years from now, and state that on that date they will publish the full list of Name & SSN data. Everyone using SSN as a shared secret must fix their databases.
You could most likely save money by renting your books, and then for the ones you want to keep, purchasing used copies of previous editions for pennies on the dollar.
UFOs are for real: the Air Force doesn't exist.
