Most of the UNIX machines at the AOC run Linux. Linux has several
desktop environments available but the two most notable are
Gnome. The default at the AOC is KDE
but there are several Gnome users too, so both will be discussed here.
While you can run just about any Gnome program in KDE and vice-versa,
it is sometimes better to use the tool that is tailored to your desktop.
korganizer is KDE's
calendaring and scheduling program for organizing appointments, todo
lists, projects and more. It is an integral part of the KDE PIM suite,
which aims to be a complete solution for organizing your personal
data. KOrganizer supports the two dominant standards for storing and
exchanging calendar data, vCalendar and iCalendar.
ical provides an X interface for maintaining a calendar.
A calendar is basically just a set of items. An item is either an
appointment, or a notice. An appointment starts at a particular
time of the day, and finishes at a particular time of the day. A
notice does not have any starting or ending time. Notices are
useful for marking certain days as special. For example, a calendar
may contain a notice for April 15th indicating that taxes are
due. When the documentation below refers to an item, it applies
both to notices and appointments.
offers many more mathematical functions than meet the eye on a
first glance; such as: a trigonometric and a statistics mode, a
'results-stack' which let's you conveniently recall previous
results, and configurable precision.
gcalctool is a basic scientific calculator for the Gnome
environment. It can do simple double precision similar to xcalc.
dc is not a graphical calculator, so it can be run over
telnet, ssh or other such connections. It is a reverse-polish
desk calculator which supports unlimited precision arithmetic. It
also allows you to define and call macros. Normally dc reads from
the standard input; if any command arguments are given to it,
they are filenames, and dc reads and executes the contents of the
files before reading from standard input. All normal output is
to standard output; all error output is to standard error.
When configuring mail readers for the
AOC, use mail.aoc.nrao.edu for
the mail server, smtp.aoc.nrao.edu for the SMTP server, and IMAP
for the protocol.
