Q: I want to log into the eidolon linux box remotely from home/dorm/cybercafe, but it won't let me. What can I do?
A: To be able to log into
eidolon when you are off campus, set up a VPN, a service provided for
free by the UBC IT Services.

Q: When I try to use my Macintosh as a terminal to the remote linux computer, emacs doesn't work/look right.
A: Since emacs assumes you have
a graphical display, you need to do two things. First, on your
Mac, use the X11 program, not the terminal program. If you can't
find the X11 program on your hard disk, you can probably find it on the
System CD that came with your Mac or your operating system.
Second, when you ssh to the remote linux box, you need to include the
-X option. For example, type the following in the command line in
your X11 window:
ssh -X YourUserID@AddressOfRemoteLinuxBox
Q: Can I run emacs directly on my Macintosh, instead of using it as a terminal to a remote box running emacs.Q: My dry adiabats don't have the right slope. They are too horizontal.
A: Perhaps, for the x-axis, you
accidently plotted temperature T, instead of getting the x-coordinate
for temperature by using the xst function.

Q: I keep getting a "syntax error" and can't find the problem.
A: Be sure that you have a
semicolon (;) at the end of each statement. Also, check that all
your parentheses match: (), [], <>, {}.
Q: Although the program
should print some output in the first lines of the script before it
gets to an error later on, nothing appears to print.
A: Although PERL is an
interpreter, it first scans ALL of your script a few times, checking
for syntax errors, and other errors. If it finds any of these
errors, even later in your program, then your program won't run at all.
Q: My file should produce some output, but it doesn't appear on the screen. Why?
A: Perhaps your output is being
written to a file, instead of to the screen. If it is written to
a file, you can view the contents of that output file by using CAT in
unix, or by opening the file using the VI or EMACS text editors.
Q: I can't get the Linux date command to work from inside Perl.
A: Inside Perl, Linux commands
must be surrounded by accent marks, not single quotes. Namely, it
should be `date` , not 'date' . You can usually find the accent
mark just above the tab key.
