 Machines behind your router (called your local area network or `LAN`) can make connections to the wider internet (known as `WAN`) but not the other way around.

+For example, HTTP traffic from a website would default to port `80`. HTTPS defaults to `443` and SSH defaults to port `22`. 
 
 To make our server accessible we need to open and forward those ports on the router/firewall to our server in a process called port-forwarding.
 
-The exact method of port-forwarding differs from router to router. However, it always follows a similar scheme where you designate inbound traffic on a certain port to be forwarded to the IP address your server has on the local area network.

Since a large part of both the appeal and the weight of the magazine comes from the fact it is richly illustrated, this presented us with a particular challenge.

 In order to reduce the size of the images, without diminishing their role in the design and the blog itself, we reverted to a technique called dithering:

+![The same image but dithered with a 3 color palette]({attach}images/international-switchboard3.png)The same image but dithered with a 3 color palette, 36.5KB
 
 This is a technique 'to create the illusion of "color depth" in images with a limited color palette'[^illusion]. It based on the print reproduction technique called [halftoning](https://en.wikipedia.org/wiki/Halftone). Dithering, or digital half-toning[^digitalhalftone], was widely used in video games and pixel art at a time when a limited amount of video memory constrained the available colors. In essence dithering relies on optical illusions to simulate more colors. These optical illusions are broken however by the distinct and visible patterns that the dithering algorithms generate.

+![Dithered with a six tone palette]({attach}images/international-switchboard6.png)Dithered with a six tone palette, 76KB
 
 As a consequence most of the effort and literature on dithering is around limiting the 'banding' or visual artifacts by employing increasingly complex dithering algorithms[^dithering].
 
 Our design instead celebrates the visible patterns introduced by the technique, this to stress the fact that it is a 'different' website. Coincidentally, the 'Bayesian Ordered Dithering' algorithm that we use not only introduces these distinct visible patterns, but it is also quite a simple and fast algorithm.
