This site is a place to post questions about problems in your classes or research. You can ask how to solve a certain kind of problem in planetary dynamics, or how to create a certain effect in an SM plot, or how to declare a variable in FORTRAN. No question is too trivial or too broad, but the more specific you are the likelier you are to get an answer. You can list your name with your question, or just post anonymously.
Post short pieces of information in the table below. To contribute a solution, create a link in the table to a new wiki page where you can list a longer discussion.

| How does one change the color of background and foreground for a document produced by LaTeX? For e.g. what if I want green text on a black background? |
In the preamble of your LaTeX document, put \usepackage{color}. Then to make the font a specific color, do:
\textcolor{color}{words to be in color}
For changing the background color, do \pagecolor{blue}.

| I'm having issues with IDL Direct Graphics- tvrd() or other device commands aren't working properly (e.g., image data stored in 2D arrays instead of 3D with R, G, B component). |
Make sure IDL is in 8 or 24 bit mode.
VNC users beware, sessions start
up in 16 bit by default. Use -depth 24 keyword when starting a VNC session.

| I'm having IDL problems since switching to v7.1. I think it doesn't know where the idl astro library is. Can anyone tell me how to add the idlastro lib to the idl path? |
IDL7.1 lives on a different server that does not seem to have astrolib installed. The astrolib package just needs to be downloaded from here and copied to /net/vpac00/usr/local/idl/idl71/lib/. This needs to be done by someone with superuser permission, so this should be resolved by submitting a trouble ticket. (Keivan submitted the trouble ticket and this is now resolved.) |
