How we cut our website’s carbon emissions in half

Between 2010 and 2030, the environmental impact of the digital world is expected to triple. While network infrastructure and devices get more and more efficient, all of these improvements are eaten up by more and more people and devices being connected to the internet, but especially by websites which are becoming more and more bloated. On the desktop, the average page weight of a single web page is four times as much now as it was in 2010. On mobile devices, it’s even more dramatic: The average page weight is ten times as much as in 2010.

Evolving software like an orchardist

Software systems are usually larger, overgrown structures that developers need to bring back into shape after some time.

The Tower of Babylon is a myth meant to explain why the world’s peoples speak different languages. In modern IT systems, it’s often a requirement to support multiple languages.

It isn’t exactly news that developers have to write not only code but also tests. Nevertheless, many find this to be burdensome and monotonous work.
