current mood

Guillaume Collombet (with assistance from LLM...) on fractal chats discord suggested using #MoebiusTransformation instead of #LinearApproximation to accelerate #MandelbrotSet #DeepZoom .

The advantage is that the quadratic term of the perturbation formula is now exact, with a cubic remainder term. for single step, assuming that z < sqrt(eps) 2Z makes this remainder be lost in rounding noise, while for the linear approximation the corresponding condition is z < eps 2Z.

given two moebius with validity radii, the validity radius for their composition can presumably be calculated without much difficulty.

eps is typically 1e-16 to 1e-8, depending on how much precision loss you think you can get away with.

Guillaume claims moebius gives a practical computational efficiency improvement over linear. I haven't tried it myself yet.

However, while I think it should work well for #JuliaSet, where composition of two moebius in z gives another moebius in z, the nonzero c term for mandelbrot set ends up with something with zc and c^2 terms when composing the two functions, which Guillaume handwaves away reasoning that c is usually tiny and z is also small most of the time. I'm not 100% convinced that iteration (composition coefficients getting larger) wont eventually make them significant...

No cat's whiskers? No problem: use two razor blades instead.

Apart from being a touch on the dangerous side, this turns out to have other downsides. It's likely to create semiconducting junctions on both sides, or on the wrong side only, and this also greatly depends on the weight of the crystal.

It's a bit easier to swap crystals though, and rotating them to find good spots is simple enough.

so good!

Aftermath of a great workshop at mulheimer zontage, looking forward to great concerts plus a cooling bath in the ruhr this afternoon. https://zongtage.net/festival/2026-programme

there's a writeup here i'm trying to get a copy of but sounds like its not gone well anyway.

this is kinda an interesting read

i guess the government / nhs perspective is, we had an open transparent tendering process, we thought about patient privacy and how to mitigate companies profiting from this, this company won, end of story

i suppose there’s just inherently nothing in neoliberal democratic systems that lets you deny a contract on the basis of them being, you know, white supremacist eugenicists

interesting that the NHS are using the language of "federation" to describe their palantir platform, i think this is the only other context i've seen it in?

Thank you to @julieblanc, @nolwennm and Clémence Imbert for this two-day symposium exploring the relationship between codes and interfaces. I’m back to my hot appartement with questions. Could the new paradigm regarding interfaces and texts be (human) language itself? With LLMs, we structure sentences just as we would with a cursor or a line of code to get what we expect from this tool (if we consider it a tool), behind which lie a vast number of procedures.

i had a mad dream last night that danny elfman and hans zimmer had traded places and elfman was scoring the next dune film while zimmer did the simpsons

This week, Sammy keeps prepping for the sneakerweb. And Aljoscha announces two albums (exclusively released to the Sneakerweb). sneakerweb

extra fun feature discovered by @paupowpow is that you can easily glitch the drawings by changing a few numbers in the svg code.

Many thanks to @NGIZero for making this possible!

Wobble Web now has a drawing tool for drawing svgs straight over your html page 🖍️

One of a few new features @paupowpow and I showed this week in Strasbourg at the Code Meets Interface study day

Un grand merci à @julieblanc, @nolwennm et Clémence Imbert pour l'organisation des deux journées Quand le code rencontre l'interface à Strasbourg et en ligne. Un incroyable lineup (et j'dis pas ça parce qu'une bonne proportion sont des copaines), de remarquables interventions, une organisation sans faille (depuis chez moi, la chaleur était parfaitement supportable), et un livetoot parfait. Bravo !
