Somewhat related: I've long wondered why ATM cards don't have something similar. 1234 is my regular PIN. 1235 is my help I'm being robbed PIN -- it dispenses the cash, calls the cops, and tags the video.

My girlfriend worked at bank that did this. The alert PIN was your PIN backwards. I don't know if they still do this or not.

I heard about this before. According to Snopes it's false although it may have been implemented in A few places.

Bank machines have this.

Diebold ATMs could be configured to send a "distress signal" when their safe was opened and the last number of the combination lock was off by 1. The option was off by default, because it required additional hardware hook-up (for the signaling), but it was there.

People have trouble remembering one PIN, memorizing two would be too much for many.

This is also why any app that handles sensitive information (including, arguably, the photo and video galleries) on a phone should have at least the _option_ to set an in-app PIN that's required before it opens up. Lots of folks hand their smartphone to their kids to play games and even if there's nothing sensitive on there, they might have things they don't want deleted like treasured photos and videos.

completely possible on android.

Nope. While on Windows, Linux, and OS X you can have two remote users logged in and independently using tty windows, they all must share the same GUI window.

On Mac OS X 10.7 (Lion), there is now multiple user screen sharing. http://www.apple.com/macosx/whats-new/features.html#screensh...

10.7 was released last year, not 40 years ago :-)

My older Mac Mini would not do it. I didn't know that this was added in 10.7.

I'd benefit from a "Driving Mode" on my phone. If John, Rachel, or Stan calls, auto-text them: "I'm driving, can't talk". Everyone else goes straight to voicemail. If they send me a text within 5 minutes of that call (must be serious), make the font huge so I can read it in .5 seconds on my console. Hide all other texts. I'd like to be truly responsible and just turn my phone off, but I don't to allow for those few t…

Siri is already the "Driving Mode" feature on the iPhone.

Hooking it up to the stereo system makes it feel like it is part of the vehicle. Some day, when I am feeling adventurous, I will wire the otherwise useless OnStar button to trigger it to complete the "factory look."

That isn't true for Linux and Windows. X (the service commonly providing the *nix GUI) was pretty much built with this in mind; Linux has had an implementation of X that has provided this since at least the mid-90s. Windows has had this on the server since at least Windows Server 2003, and has also introduced it to the "consumer" market in Windows 7. (I'd be happy to find out whether OS X supports this or not.)

I tried to do this couple years ago for Linux, asked around, and was told this was not possible for Linux. Apparently I was misinformed. I'm happy to be wrong about it. Can you point me to instructions for doing it for Ubuntu?

I have Windows XP, and have had 2000, NT, 98, 95, etc., and none of them could do it.

I'm glad to see that finally this "40 year old technology" is getting onto desktops in the last year or so.

Out of curiosity, do you know what happened if the pin number was a palindrome? Did they restrict your selection to prevent that?

Yes, they restricted the selection. They also encouraged each number to be unique.

That's a funny requirement. Requiring uniques reduces password strength.

Yes, they restricted the selection. They also encouraged each number to be unique.

For the interested: enforcing no palindromes and unique digits reduces the number of possible PINs by about a factor of 2, bringing it down to 5040 4-digit combinations.
