This handbook provides a brief overview of environmental harm driven by software, and how the Blue Angel ecolabel—the official environmental label of the German government—provides a benchmark for sustainable software design.

I always loved the visual aesthetic of dithering but never knew how it’s done. So I did some research. This article may contain traces of nostalgia and none of Lena.

It’s always safe to assume JavaScript will not be available, so here’s a quick list of very realistic reasons it won’t be.

A 14kB page can load much faster than a 15kB page — maybe 612ms faster — while the difference between a 15kB and a 16kB page is trivial.

This is because of the TCP slow start algorithm. This article will cover what that is, how it works, and why you should care. But first we'll quickly go over some of the basics.

This talk is called An Approach to Computing and Sustainability Inspired From Permaculture. Sustainability is an awful word, that doesn't really mean much anymore. What I mean by this is being able to do something for a sustained amount of time. Permaculture is also an equally vague concept, when I say this, I mean that it is something that has a strengthening effect on the ecosystem.
I'm interested in computers as a way to do more than consume, as a tool of creation. For that reason I won't consider services, or apps. This talk is about open specs and on building knowledge to write your own software.
I'm going to present technologies, but I won't give you their names, because my goal is that you will develop your own systems. I'm not selling you on any one technology.

The use of images increases the size of a web page which considerably lowers the load speed of the page. To improve the speed of your website it is important to consider compressing or resizing images.

Aiming for a 10 year life-cycle for smartphones

This website is solar-powered and self-hosted. It has been designed to radically reduce the energy use associated with accessing our content.

A naturally intelligent network programmed by the sun.

Sun Thinking is a group exhibition that brings together artists, writers, and researchers to explore the qualities and logics of solar power and solar powered computing networks. It presents a collection of network-based artworks, games, texts, and interviews and is the first exhibition project to be hosted on the Solar Protocol network.

A game jam that focuses on creating energy-efficient games

When designing computer systems, one is often faced with a choice between using a more or less powerful language for publishing information, for expressing constraints, or for solving some problem. This finding explores tradeoffs relating the choice of language to reusability of information. The "Rule of Least Power" suggests choosing the least powerful language suitable for a given purpose.

Permacomputing is both a concept and a community of practice oriented around issues of resilience and regenerativity in computer and network technology inspired by permaculture.

In a time where computing epitomizes industrial waste, permacomputing encourages the maximizing of hardware lifespans, minimizing energy use and focusing on the use of already available computational resources.

On the need for low-carbon and sustainable computing and the path towards zero-carbon computing.

Wim Vanderbauwhede takes a look at the environmental cost of computing and argues that it must change radically if we don't want it to further fuel the climate crisis.
