Comment Primitive Operating Systems use extensions (Score 1) 564

The use of file name extensions to indicate file types is a feature of some Digital Operating Systems like VMS that has been aped by CP/M and MS-DOS. The MacIntosh System uses a separate file type indicator and Unix uses magic (4) bits even though they sometimes use suffixes for C source files.

You all learned the answer in high school: if you have a wave, then you can reduce its amplitude or extinguish it by adding a copy if the same signal with the opposite phase.

This has been done to reduce acoustical noise, but it's rather harder to accomplish with light waves. But then, holography is all about interference.

In space, no one can hear you fart.
