Great Movies: District 9

District 9 is one of these movies that tell you a lot of real-world stories using exotic, if not superficially irrelevant, metaphors. In this case, the metaphor is simple: aliens have come to our planet, but without a clear purpose (peaceful or not). Rather, an alien mother-ship appeared over a South African city one day in 1982 and stayed there until the humans decided to enter and investigate what’s in there.

How to get free signed SSL Certificates and setup secure domains in Apache and Debian

This how-to describes the process to obtain 100% free, signed SSL Certificates from StartSSL.com and configure Apache in Debian to use these SSL certificates in your virtual domains, so that people can access your site(s) through https (i.e. https://example.com) without ever having the browser tell them the scary “this site isn’t trusted” anymore.

Before you start, you will need:

  • One or more of your functional domains which point to a server you own and have root access to. In this tutorial I’ll be using my wife’s supersyntages.gr as testbed.
  • A browser, for this tutorial Chrome, although you might prefer Firefox (see below why).
  • Root access to your server with Debian and Apache installed, with the above domains configured as VirtualHost.
  • The openssl package installed in your computer.
  • One of the following emails configured in each of the domains you want to include in the SSL certificates:
    [email protected]
    [email protected]
