“It’s kind of quirky,” said one person — in an age of hype around how endlessly bigger and faster and smarter tech can be, they thought this event felt surprisingly quaint and charming. We were talking about tech, sure, and it was a group of people who were interested in tech, in general, but we were there intentionally to look through the lens of a technology and medium that can feel almost retro.

Computer people are fine human beings, but they do a lot of harm in the ways they "help" other people with their computer problems. Now that we're trying to get everyone online, I thought it might be helpful to write down everything I've been taught about helping people use computers.

The homebrewserver.club is a monthly gathering for those who (wish to) host their own online services from home, rather than using commercial and privacy unfriendly alternatives. Together we config and work on our homebrew server setups. These are low-cost, low-power, low-maintenance, high-fun computers through which we can host all of our online necessities and keep them out of the cloud. The club meetings are open for anyone, from more experienced users to interested beginners. During the homebrewserver.club meetings we exchange tips or look into particular topics together. As we gain more knowledge about a topic, we write and publish guides for others to share.

Many of us have old phones or tablets sitting in a drawer at home. They might have a dead battery or broken screen that keep us from using them, but in theory they are still quite functional computers. Imagine if we could install a new operating system and make them useful for new purposes: a tiny web site, small home server, media player, sensor station or even stranger, more poetic things. Thanks to efforts like PostmarketOS this is possible, but it can be intimidating and confusing.

In this workshop, we will attempt to install the Linux-based PostmarketOS on "obsolete" Android devices and find convivial new uses for them.

With pairs of comically oversized exhaust pipes pointing towards the sky and enormous stacks of grey cooling aggregates flanking its sides, AMS09 resembles a child's drawing of an exaggerated, imaginary factory. Despite being painted in a variation of “Go Away Green”, a colour engineered by Disney to draw visitors’ gazes away from technical facilities across its amusement parks, the building miserably fails to blend in with its surroundings.

Networks of high-quality ground-based GNSS stations provide maps of ionospheric total electron content to correct these errors, but large spatiotemporal gaps in data from these stations mean that these maps may contain errors. Here we demonstrate that a distributed network of noisy sensors—in the form of millions of Android phones—can fill in many of these gaps and double the measurement coverage, providing an accurate picture of the ionosphere in areas of the world underserved by conventional infrastructure. […] This work demonstrates the potential of using a large distributed network of smartphones as a powerful scientific instrument for monitoring Earth.

A blog post by https://kopiti.am/@nondescryptid detailing how they set up postmarketOS on their own phone:

I’ve got a Samsung Galaxy S II (i9100) lying around, and decided to try seeing if I can repurpose it and get it to host a blog. I was inspired by compost.party – a very cool server running off a Xiaomi Poco F1 using postmarketOS and a solar panel for charging.
The physical nature of computing is usually not a concern, as things are sufficiently abstracted for me to not have to care too much about it. But trying to revive this phone from 2011 was a reminder that when we talk about compute, we are ultimately dealing with physical resources – tiny towns with blocks of silicon, lithium, etc etc.

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.

HTML energy is all around us and in this very website.
Building websites has become complex,
but the energy of HTML persists.
What makes HTML special is its simplicity.
HTML isn’t a vast language, yet you can do a lot with it.
Anyone who wants to publish on the web can write HTML.
This accessibility and ease of use is where its energy resides.

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.

Explore millions of photos, audio recordings, and videos of birds and other animals; powered by Macaulay Library and eBird. The Macaulay Library collects, archives, and distributes wildlife media for research, education, and conservation.

Billions of phones will be hoarded in drawers and cupboards or thrown away rather than recycled, studies suggest.

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.
