The new Google Phone's Android platform apparently has a very serious (but hilarious) bug. When the phone starts, it opens up a command shell with root privileges in the background, and everything you type on the keyboard is sent to that shell. For example, if you type "reboot<enter>", it reboots the phone.
Does it make me a bad person that the first question that occurred to me upon reading about this was, "Hmm, what would be the best way to get a G1 user to screw themself over?"? Here's my suggestion, which uses chat:
A: Sure [or whatever -- gets them to hit <enter> and prepare for a new command]
Q: Somebody told me, but I forgot: what's the worst thing you can type at a Unix command prompt?
A: rm -rf / [and hilarity ensues]
This only works with people who know Unix, though—a non-tech-savvy person can only respond, "Hell if I know". Can we come up with things that we can reliably get a non-geek to type? Here's a thought: if you can get someone to type "<enter>yes [anything]<enter>" (which must happen all the time in messaging and chat) it will start up the Unix yes command, which will run forever and peg the processor. I'll bet that runs down the battery really fast. Fun!
