@freebliss I wouldn't be surprised if there's a bad feedback loop in which "trying it with multiple browsers" automatically looks suspicious, i.e. looking like multiple different agents from one IP.

January 26: Recursive Grids. Split the canvas into a grid of some kind and recurse on each cell again and again.

Construct a line through the middle of the canvas, whose orientation is taken from a fixed set of regularly spaced angles. That divides the canvas into two polygons. Recursively apply the same splitting process to those polygons, up to some maximum depth, then draw them. The result is something like an ice ray lattice.

For those who weren't active in this space in the early 2010s, I cannot emphasise enough how stuff like the patterns for wind and solar deployment below were thought of as fundamentally impossible, and how nutty you sounded when you gently suggested we should even try

This is me trying to get to work this morning... When @chuuchuu says Dutch trains are a LOT more reliable than German ones, I really wonder! (This morning's timetable is annoying but not unprecedented. I'm still going out to get on that one disrupted but not cancelled train)

If my toot sounds tired, then these little red warnings under each train on the timetable must be the reason. Journey not possible, cancelled, disrupted, cancelled, etc

Fun times ahead, I'll be in Eindhoven for a few days weds-fri this week, visiting @kand, Pei-Ying Lin and co in their textile lab at tu/e to explore controlling a hacked TC2 loom like a musical instrument together

I'll also be at the live coding meetup at blablalab in Eindhoven on Thurs 29th to hang out with Wilbert Vogel and co instagram.com/p/DTutl8FjJ1z/

Then on to Düsseldorf to visit @julian with @Khipumancer @nebogeo on 31st Jan, to talk about andean khipu and cornish mines wertlos.org/epi/beingformal/ - join us if you're nearby!

Then back to Sheffield to host Janani Suresh Ram the following week to explore bharatanatyam dance and live coding.. Plus she'll run a workshop on bharatanatyam and mathematics on 5th Feb patternclub.org/sheffield/

@d6 for a moment I thought you had implemented NoiseTracker. One day...

Goodbye to the idea that solar panels “die” after 25 years. A new study says the warranty does not mark the end, and performance can last for decades. Arrays built in the late 1980s still produced more than 80% of their original power. The long-term economics look better than many people believe. bocvip.com/1170237/goodbye-to- #energy

The thin ice layers on the canal like the skin on hot milk. And the visceral memory of the disgust I felt as a child if any of the skin made it into my cup or plate. The cold making me bundle up, in the down coat I used in my last - record - winter in Boston. This is now a decade ago - how? I still feel like that child sitting at the kitchen table with milk skin in her hot chocolate, all the way to the world order crumbling around me.

@harry_wood I do this! I usually do it using USB but my top tip would be SyncThing. For Android<->MacBook I expect it to work great for over-the air casual transfer.

Commander Vimes didn't like the phrase 'The innocent have nothing to fear', believing the innocent had everything to fear, mostly from the guilty but in the longer term even more from those who say things like 'The innocent have nothing to fear'.

Reading this report is shocking. No matter how familiar the topic is to me, seeing it in blunt government-report terms is stunning. Look at the "Key judgments" on the first page. "Every critical ecosystem is on a pathway to collapse (high confidence)" ... "it is unlikely the UK would be able to maintain
food security (moderate confidence)" ...

Very pleased to announce that the next edition of Cloudbreak will take place on Feb 16, & with a few enhancements to both content and pace.

This is a great opportunity to not only take your first steps into the craft of ethical server administration, working from a best-practice base, but to become part of the solution in an era of runaway digital imperialism, surveillance capitalism & Internet enshittification.

Quite a phenomenal campaign ad from the Greens down in England. Strong. I firmly believe that any political party not running this same message will fail.

A talk on #39c3 by @pluralistic about building an #enshittification resistant internet.

Very highly recommended!
