Getting my thermodynamics lectures ready for this year. The Sankey diagram for the UK's energy demand in 2020 shows that for all the back slapping about renewable electricity, the scale of the challenge to decarbonize remains absolutely gigantic. I put this alongside the graph shown by @andrewdessler recently about where our emissions need to be in the 50 years. Even a government that isn't asleep at the wheel will find it hard. Very hard.
He slow-travelled from Germany to Papua New Guinea for a field trip, taking boats, trains, busses, and #notflying.
There he talked about #climatechange with locals and made a promise not to fly on his way back either.
Then his institute sacked him for wanting to slow-travel back and not get on a plane to Germany.
He is our hero and he is on his way back on boats, trains, busses.

Holy shit I think I’m in love.
#Protomaps, a way to serve vector #maps of the entire world using a single static file and HTTP range requests.
It’s basically a static site generator for interactive maps. Tile servers are pretty much obsolete now. No database needed, you can run your interactive, smooth-zooming vector map from any HTTP storage. S3, Caddy running on your Wi-Fi router, even GitHub pages.
It’s open source & free to use. Wow. 🤯
Engineering professor and materials scientist @debcha's new book *How Infrastructure Works* is a hopeful, lyrical - even beautiful - hymn to the systems of mutual aid we embed in our material world, from sewers to roads to the power grid. It's a book that will make you see the world in a different way - forever:

A very inspiring book i'm sinking into right now is a free read of "Art + DIY Electronics" by Garnet Hertz.

I've gone through 3 million manuals in the Internet Archive's collections and produced a "Manuals Showcase", a few dozen manuals that are sure to catch your eye here and there. Readable online, downloadable, and ad-free.
How retro kick ass is that? Flash is resurrected sans the neglected, proprietary, security ridden, plugin bs of Adobe; thanks to Rust, and modern day sandboxed WebAssembly. No plugin required; small, compact, compatible engine, that unlocks decades of lost SWF content in all its vector visuals, MP3 stereo, and ActionScript-y glory. https://github.com/ruffle-rs/ruffle #flash #adobe #webdev #javascript #rust #retrogaming

More than four decades after this tech was introduced we could have had a Europe-wide dense network, cross-linking all regional centers from Oulu to Seville, Edinburgh to Athens, Brest to Luhansk. Maybe we could have had sleeper high speed trains. Maybe we could have closed many airports, and made flying very unappealing, without antagonizing families and friends that live scattered away.
But we don't have any of that.
Instead of building and operating infrastructure for the common good, we have elected and non-elected moronic bean-counters forcing what should be public utilities to compete with each other in a race to the bottom.
"Tailpipe" emission is zero, lifecycle emission is around 3 grams CO2 equivalent per passenger*kilometer, significantly less emissions that a _mechanical bike_ ridden by someone with a _fully vegan diet_.
Hypothetical medium range "clean" planes, or plans for highway with hydrogen refill stations, are a foolish distraction from the fact that **sustainable transcontinental long distance mobility is a solved problem, with well defined advantages, limitations and a proven track record**.
#POV #train #TGV
You're traversing a continent at nearly 300 kilometer per hour, in relative silence, high comfort and with an incredibly high level of safety.
This is a double-deck double-train, so around 900 passengers are enjoying the same journey.
This specific Lyon-Paris line was opened in 1981, one year after I was born. From the rolling stock to the infrastructure, most of this technology is more than 40 years old, with small incremental improvements here in there.
Hey folks, I've seen a lot of talk going around about adblockers lately. I worked in the advertising technology and security industry for five years and the one core piece of advice I have is:
Holy fuck never give an advertiser your data. You cannot believe how bad it is. Don't. I run three layers of ad block protection and I'd run more if it was feasible. If you want to support creators give them money.
Hacker leaks millions of 23andme genetic data profiles.

It's funny: Both Bandcamp and Patreon had the easiest and most straightforwardly long-term profitable business models imaginable: Sit between indie creatives and their fans, provide some basic services for mediation (comment sections, media posts, semi-global payment) and take enough of a cut of any payments to cover the costs and then some.
But because that business model wouldn't scale forever, they are instead being gutted, because ever _increasing_ growth is the only model capital accepts
No wonder they get so worked up about language models, they truly see themselves in them?
Our home cable-based internet had 10kBit/s upload speed yesterday and I needed to get 200Mb to a printshop.
