... Sometimes a background process or a process without a controlling terminal hangs up and you will need to destroy this process by killing it. To kill a process use the kill command. kill [-signal] process_identifier (PID) . ... Always try to kill a process with a simple kill command. kill process_identifier . ... If this does not work use the -1 (one) signal. kill -1 process_identifier . ... As a last resort use the -9 signal: kill -9 process_identifier . ... Using the shell built-in kill command . ...

On 12/1/97 I got the first clear night since 1997dt was reported. I just took the camera apart for cleaning, and I didn't get a chance to make twilight flat fields tonight. Thus the edge is darker than the center of the field. I'll correct this if it's clear tomorrow night. The image was taken with C14 @f4 and CB245 CCD camera. ... The field of view is about 12 X 9 arcmin. The supernova is the star just west (right) of the nucleus. Back to Supernovae in NGC and IC galaxies. ...

ABSTRACT: Both previous radiomessages for aliens, Arecibo 1974 and Evpatoria 1999 (see http://ebe.allwebco.com/Science for details) were the logical ones and represented the binary stream of FM information, which should be arranged into two-dimensional forms to perceive by eye-like sense-organ. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... The theremin was invented 80 years ago, in 1920 by Leon Theremin. ...
