“Simulations suggest that the extensive Copenhagen bicycle lane network has caused the number of bicycle trips and the bicycle kilometers traveled to increase by 60% and 90%, respectively, compared with a counterfactual without the bicycle lane network.

This translates into an annual benefit of €0.4M per km of bicycle lane owing to changes in generalized travel cost, health, and accidents.”

-> Those bikelanes have a payback time of a few years!

#WireGuard becomes the first VPN app on #FDroid to be built reproducibly! This means that WireGuard on F-Droid is now guaranteed to be 100% (bit-by-bit) equal to the WireGuard the developer builds.

If you're using WireGuard from F-Droid, please export your tunnels and re-install to switch to the developer's signature and continue receiving updates.

More details in the official WireGuard announcement: https://lists.zx2c4.com/pipermail/wireguard/2023-April/008045.html

This 3d-printed bike is absolutely bonkers, but I think the core takeaway from this video is that everyone should have somebody in their life who says their name the way Ollie Bridgewood says "aero".

We're looking for help to build a wireless, solar-powered chat network across the Philly area! Are you interested in learning about off-grid solar power? Do you have a sunny place on your roof, in your yard, or near an upstairs window where you can leave a small radio transceiver? This workshop may be for you!

Each participant will receive a free kit with all the parts needed to build a solar-powered LoRa radio node. You'll assemble the kit, mount it in a weatherproof enclosure (provided by you), and use the Meshtastic app to start sending encrypted text messages.

Registration opens Monday, April 3rd at 8:30 p.m. You can sign up on our site:
https://iffybooks.net/event/solar-chat-network

Supplies for this workshop are provided by a grant from the Engaged Humanities Studio at Swarthmore College. Many thanks to @pixouls for helping plan the event!

The thing that drives me nutso about climate change is that many of the necessary changes could be awesome. A society with more leisure time, cleaner air, closer connections to friends and family who live nearer to you, more exercise, more technological innovation, more jobs, more fairness, more nature… most people would benefit from these changes.

A few weeks ago I wrote about how viral Mastodon posts get hundreds of replies, but most people can see only a small fraction of those replies, and bad UX results. Here’s a solution for folks running smaller Mastodon servers. https://fedi.aeracode.org/@andrew/110029009466041431

@eighthave that sounds nicely put: Android used open source as a TOOL to get developers on board, and now that everyone is on board, is increasingly hostile to open source and has largely abandoned AOSP apps and functionality that they can replace with the Google Mobile Services "ecosystem". Additionally, SafetyNet (now Play Protect) lets developers "optionally" lock out people who exercise their right to modify free software (such as their OS)... and still actually run it.

An analysis of 100+ studies finds that social media is a major cause of mental illness in teen girls, not just a tiny correlate, especially after 2012 (Jon Haidt/After Babel)

The bundling video streaming services are rapidly becoming indistinguishable from the cable services' behaviors that inspired so-called "cord cutters" cancelling cable TV services in preference for Internet-only services.

Prices keep going up as they include more and more "niche" channels with small viewerships, that nobody would pay for if they weren't forced to as the price of receiving the channels that they actually want to see. This often includes forcing sports channels on people who loathe sports channels.

For a recent story, instead of Mapbox, The Post used OpenMapTiles, Maputnik, PMTiles, and MapLibre to produce interactive web maps.

From a discussion on a major #HigherEd forum by a senior campus leader,

"We are a #Google school…"

If the comment was, "We are a Coca-Cola school," I suspect we'd hear concerns: marketing products to students, corporate influence in #HigherEducation, even health & safety/quality (all BTW applicable to Google).

If you believe Google (or #Microsoft, #Adobe) is a "global standard," the same case can be made for Coca-Cola (Pepsi). I doubt stating such an alignment would be so promoted.

Metro.co.uk headline "Tesla goes down across Europe leaving some drivers unable to charge cars" https://metro.co.uk/2023/02/14/tesla-goes-down-across-europe-leaving-some-drivers-unable-to-charge-cars-18282364/

DID YOU KNOW? You can actually design electric cars that can charge their batteries WITHOUT AN APP or any computers of any kind? Kind of like how gasoline pumps used to work? Sure, a battery pack with a microcontroller tends to be more efficient, but it is not strictly necessary. The electric motors of the car must be fully computer controlled, but these computers need not be tied to apps either.

Electric cars all being designed to become useless without an app controlling them is not inherent to electric car technology itself. It is a result of modern day #consumerism (capitalism) where every single business on the face of the Earth gathers data about you, and earns money from selling #ads to you. IT DOES NOT HAVE TO BE THIS WAY. This is what @pluralistic calls #enshitification .

And I can't wait to hear people argue with me about how gasoline-fueled cars are better and more reliable because their engines work just fine without apps or cell phones. Electric cars could be this way too, but due to the way businesses make money nowadays, they do not.

It occurs to me I haven’t done a #myfavoritethings for awhile, so let me share with you the work of Ken Isaacs. I first discovered his “How To Build Your Own Living Structures” in my hippie-school library when I was 13, and it blew my mind (in the parlance of the times). It’s a book of DIY recipes for brilliant, idiosyncratic modular structures that saddle the gap between furniture & architecture; to this day I dream of building myself a Superchair. Get yr own copy here! http://letsremake.info/PDFs/k_isaacs.pdf

Me: Write a TED talk about the bullshit of TED talks. Include anecdotes and statistics. Also include a humourous aside about a mule with a spinning wheel. End with "Thank you for attending my TED talk."
