Abstract: “This paper describes how principles derived from degrowth can be a useful heuristic for designing an ICT system within energy limits. It does so by discussing the design choices behind https://solar.lowtechmagazine.com, an ongoing design research project that set out to build a ’low-tech website’. This research resulted in a design which is lightweight, tailored towards older and lower-powered devices, is powered by off-grid solar energy and thus designed with energy scarcity in mind. The project shows that values and frameworks theorized within the Computing within Limits community are technically applicable to practices of web development but also identifies hurdles to their more widespread applicability.”

In 2020, our solar powered website obtained an uptime of 95%, meaning that it was offline for 444 hours or 20 days. Unsurprisingly, most of the downtime is concentrated in the winter months.

The graph above (click to enlarge) shows battery storage capacity in relation to the weather in Barcelona from January to December 2020. Yellow is sunny, grey is cloudy, blue is rain. From May to November, we were online without interruption for almost 6 months.

The data were collected and visualised by Roel Roscam Abbing and David Benqué.

The Galaksija computer was a craze in 1980s Yugoslavia, inspiring thousands of people to build versions in their own homes. The idea behind them was simple – to make technology available to everyone. Free play was implicitly encouraged: the sharing, collaboration, manipulation, and proliferation of software was built into Galaksija’s very operation.

A computing enthusiast since 1979, Zoran Modli caught wind of Galaksija after the publication of Computers in Your Home. As host and DJ of Ventilator 202—a renowned New Wave radio show on Serbia’s Radio Beograd 202—Modli was something of a minor celebrity in Yugoslavia. Because all the day’s computers, including Galaksija, ran their programs on cassette, Regasek thought Modli might broadcast programs over the airwaves as audio during his show. The idea was that listeners could tape the programs off their receivers as they were broadcast, then load them into their personal machines.

An overnight sensation, this DJing practice quickly became a staple on Modli’s show. In the ensuing months, Ventilator 202 broadcast hundreds of computer programs. During the hour, Modli would announce when the segment was approaching, signaling to his listeners that it was time for them to fetch their equipment, cue up a tape, and get ready to hit record. In the case of games, users would “download” the programs off the radio and alter them—inserting their own levels, challenges, and characters—then send them back to Modli for retransmission. In effect, this was file transfer well before the advent of the World Wide Web, a pre-internet pirating protocol.

This book is a guide on how to build a community network, a shared local telecommunications infrastructure, managed as a commons, to access the internet and other digital communications services. It was written collectively by a group of community network pioneers in Europe, activists and researchers during a writing residency week held in Vic, Catalonia in October 2018.

Meant for a wide audience, the book includes practical knowledge illustrated by several hands-on experiences – a set of 32 real-life stories – as well as legal, technical, governance, economic and policy material extracted from netCommons, a three-year-long research project supported by the European Commission. Its goal is to guide the reader through a set of actions aimed at setting up and fostering the growth of a community network, but also, for policy makers, local administrations and the general public, to create the right conditions to let community networks bloom and flourish.

First, Roussilhe built his site with a user friendly content management system (Kirby), which is then converted into a static website. Compared to our approach, this makes it easier to build a light-weight website for those who are accustomed to working with WordPress.

Second, the designer also tackles his videos, which are hosted on Vimeo and Youtube, and manages to reduce their “weight” by 75%. This is a major contribution, because video takes up the largest share of internet traffic.

Here’s his own conclusion:

If we take stock: I reduced the weight of my site by 10, the average weight of a page by more than 3 and I reduced the weight of my videos on third-party services by 4. I have a site extremely simple to administrate, very light so very fast, which consumes very little electricity and therefore emits little GHG.

The site also follows all the canons of today’s digital design: mobile-first, accessibility, loading speed. In fact it is quite surprising to realize that structural limitations (weight / energy) lead to navigation experiences much more accessible to all audiences regardless of their equipment, their connection or their imperative motricity or vision.

“At first glance, it seems like the ultimate paradox: A magazine that exists only on the internet, filled with content that can only be consumed once a would-be reader has disconnected from the internet. But that’s exactly the kind of contradiction founder Chris Bolin says he was going for when he created his new magazine, The Disconnect, which launched in February.” Read more: A new digital magazine forces you to unplug from the internet.

“Facebook is not introducing people to open internet where you can learn, create and build things,” said Ellery Biddle, advocacy director of Global Voices. “It’s building this little web that turns the user into a mostly passive consumer of mostly western corporate content. That’s digital colonialism.”

Bitcoin is back in the spotlight these days thanks to some wild price movements and central bank meetings. The decentralized currency has recently been trading over its all-time high of $1200 on some exchanges. But the higher the price goes, the more it exacerbates bitcoin’s dark side: shocking levels of electricity consumption.

In 2015, I wrote that bitcoin had a big sustainability problem. Back then, each bitcoin transaction represented roughly enough electricity to power 1.57 American households for a day— approximately 5,000 times more energy-intensive than a credit card transaction. Since it’s been two years, it’s time for an update.

Updated calculations with optimistic assumptions show that in a best-case hypothetical, each bitcoin transaction is backed by approximately 90 percent of an American household’s daily average electricity consumption. So even though that’s still about 3,994 times as energy-intensive as a credit card transaction, things could be getting better since 2015.

Unfortunately, it’s more likely that things are getting worse. A new index has recently modeled potential energy costs per transaction as high as 94 kWh, or enough electricity to power 3.17 households for a day. To put it another way, that’s almost enough energy to fully charge the battery of a Tesla Model S P100D, the world’s quickest production car, and drive it over 300 miles.

Pretty Fly For A Wi-Fi revisits the histories, origins and uses of self-made Wi-Fi antennas. Many of these designs were once shared through home pages that no longer exist and are now only partially accessible through the Internet Archive. It is a combination of pots and pans, dishes and cans through which people from around the world give shape to their collective dream of making an alternative internet.

This project tries to revive these designs by rebuilding, testing and documenting them. The antennas serve as an interesting point of departure to think about the internet’s infrastructure and how day-to-day users could potentially influence its shape and use.

Most of the antennas result out of the idea of wireless community networks, an idea which emerged shortly after the commercial introduction of Wi-Fi equipment in the early 2000s. These grassroots initiatives aim to build alternative network infrastructures, often on a peer-to-peer basis and without the need for costly wires. Such network infrastructures can be found on rooftops, balconies and windowsills and can cover large distances by broadcasting from building to building.

They are built for a variety of reasons, sometimes to provide broadband connections in areas where there are none, to make censorship free alternatives to the internet or to share the costs of a single internet connection.

The WiderNet Project is a non-profit organization affiliated with the University of North Carolina – Chapel Hill that promotes low-cost information and communication for underserved populations.

The eGranary Digital Library, also known as “The Internet in a Box”, is an off-line information storehouse that delivers educational resources to people living in underserved areas of the world.

• In developing countries, many of the universities, schools, clinics and hospitals have no Internet connection.
• Institutions that are connected to the Internet have such limited bandwidth that they cannot offer free Web browsing to the majority of their staff and students.
• Bandwidth in Africa can cost up to 100 times what it costs in the U.S., so for some organizations a slim Internet connection can consume the equivalent of one-half their operating budget.
• Even for those individuals who have the wherewithal to pay for Web browsing, the experience can be frustratingly slow — it can take hours to download a single audio file.

The eGranary Digital Library addresses these issues by moving a large assortment of educational Web documents onto the subscriber’s local area network (LAN) so that the documents can be made available to everyone within the institution freely and instantly.

“It turns out that digital devices and software are finely tuned to train us to pay attention to them, no matter what else we should be doing. The mechanism, borne out by recent neuroscience studies, is something like this:

• New information creates a rush of dopamine to the brain, a neurotransmitter that makes you feel good.
• The promise of new information compels your brain to seek out that dopamine rush.

With fMRIs, you can see the brain’s pleasure centres light up with activity when new emails arrive.

So, every new email you get gives you a little flood of dopamine. Every little flood of dopamine reinforces your brain’s memory that checking email gives a flood of dopamine. And our brains are programmed to seek out things that will give us little floods of dopamine. Further, these patterns of behaviour start creating neural pathways, so that they become unconscious habits: Work on something important, brain itch, check email, dopamine, refresh, dopamine, check Twitter, dopamine, back to work. Over and over, and each time the habit becomes more ingrained in the actual structures of our brains.”
