What programming languages are available on the lab machines?
On Microsoft Windows or Fedora Linux you should easily be able to find Java IDEs like BlueJ, Greenfoot, Netbeans and Eclipse in the application menus offered by the desktop.
On Windows there may not be a shortcut for Eclipse in the programs menu... but it is probably there... just type in eclipse in the Windows start-menu search.
Most OSes also have C (GCC or VisualStudio), C++, Objective C, PERL, Python, CLISP, Assembly, and Pascal (Lazarus IDE).
If you need access to a programming language that isn't available, just ask the system admin.
