I occasionally drive past a sign that looks basically like

I don't know what that has to do with the flip car but I no longer need to watch Fast 6 Furious.

Did they put it in the plane?

Your laptop might have internal USB, but it might not be easy to use as it's intended for options installed while the computer is being assembled.

Looks like that image causes comment truncation.

I can't think of any notably pretty car engines that haven't been mentioned, and a good number of motorcycle engines have already been shown...I quite like the Feuling W3

AT&T Unix isn't a standard, so many derivatives/clones don't match.

there's also apropos
