Mac: location of hosts file

The hosts file on Mac is located at: /private/etc/hosts
The easiest way to modify it is using pico, you need to have WRITE permissions to do so.

 ~ $ cd /private/etc/
 /private/etc $ pico hosts

Eclipse: show line numbers

In case you write a code to test your anti-virus software you will need a "test virus file" that does not actually wipe out your computer, you can download it from this site...
