They could even book a flight in the victims name.
That's OK, the TSA's security is so good that the crackers could never actually do anything with the false booking.
LASIK only makes sense if you're eyes are stable and not still getting worse. I'm 38 but every couple of years my prescription gets updated to correct my ever-increasing nearsightedness.
I wish my eyes were stable, I'd get LASIK in a heartbeat if I had confidence that I wouldn't need to start wearing glasses again 2 to 3 years after the procedure.
Take a close look at text printed on 600dpi and 1200dpi monochrome printers, and you can't tell the difference without the aid of a magnifier. Even text from a 300dpi printer will only be slightly less sharp.
But if you look at a grayscale (or color) image printed at those resolutions, absolutely you will see the difference. This is because the extra resolution has the effect of enabling more color levels through halftoning. The extra resolution is used to compensate for the low bit depth, not to add detail.
A printer has an inherent depth of only one bit: a drop is either there or it is not. Displays have much more bit depth and can get by with a lower resolution as a result.
I'm not making any claims about the retina display, I'm just pointing out why display and print resolutions aren't directly comparable.
Duh. That would be the point, wouldn't it?
APL hackers do it in the quad.
