... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

Make a copy of your shell start up file before editing it to change environment or shell variables. You can always return to using this copy if you find that the modified file is not working and you are unable to fix the problem. For example: cd cp .profile old_profile ue .profile . The first command changes you to your home directory, where a copy of the file .profile is made in old_profile . ... To revert to using the original .profile you simply copy it back. ...
