Compatibility Challenges

At the time I made this cartoon and when it was  published first in "Die neue Schulpraxis (02/2014), I didn't have any concrete scenarios in mind, but it happened just by accident that this cartoon now fits perfectly to an issue I faced recently where we deployed an updated version of the back-end software which was incompatible to very old client applications that communicate to our back-end system.

Arctic Tennis

First cartoon this year..

BTW, I was asked whether it was by purpose that I took a FEMALE penguin sitting on this tennis ball. Not really. The truth is, first I used a male penguin but then I suddenly questioned whether male penguins do hatch eggs. I wasn't quite sure but I still had in my mind that male and female are taking turns between each other. At that time it was already too late to verify (01:00 am) and I was too tired to do proper investigation. In the meantime I verified it. Both penguins are breeding the eggs. While one is hunting for food, the other takes over the breeding job.
