One thing which does not seem to be mentioned on the Astronomy Department website is that you can install IDL on your laptop and then get a copy of the department license. Go to http://www.ittvis.com/download/download.asp?urlProductCode=10 to download IDL, following the instructions at http://download.ittvis.com/idl_7.0/linux/web_install_idl_all.html given by ITT. There is also some information about licenses on the download instructions page. Copy the file /apps3/rsi/idl_7.1/license/license.dat from lupus in to whichever directory the ITT website tells you to use. Then, in the first uncommented line in the license.dat file, replace lupus with lupus.berkeley.edu and save. Once you have done this, you'll need to set up your IDL environment with a .idlenv file, as described on the department guide http://astro.berkeley.edu/resources/computing/idlusers/idlsetup.html | One thing which does not seem to be mentioned on the Astronomy Department website is that you can install IDL on your laptop and then get a copy of the department license.
