My desktop computer's screen is a CRT run at 1024 x 768 x 16777216. Its 
diagonal is (now where's my ruler? Ah, here) 38 cm, which means (let's 
use Vim's new floating-point feature to compute that) 38/2.54 = 15 in, 
give or take 1/25 in. (about 1 mm) which is within the limits of 
experimental error.

I've had excellent eyesight most of my life, but now (with old age, at 
not even 60, ah lala) I need glasses to read. The ones I'm wearing at 
the moment seem excellent for my sight, no fatigue at all.

IIUC, aliasing gives better curves at large sizes while non-aliasing 
gives crispier fonts at small sizes.


Best regards,

Improve its object code.
And even as we speak does it
Increase the system load.

How patiently it seems to run
And spit out error flags,
While users, with frustration, all
Tear all their clothes to rags.
