I made a plot showing the historical evolution of the pay ratio between the highest and lowest wages, for four countries. I like this kind of long term economics.

2026, the Year of JPEG XL
JXL adoption has been a surprisingly dramatic saga. But it looks like in 2026 all pieces of the puzzle might finally come together.

> In the end [JPEG XL] is just a codec and the the main purpose of it is to allow you to forget that there *is* a codec – and to just use images. For me [codecs are] very interesting at the technical level, but the goal is to just make images work seamlessly. www.youtube.com/watch?v=3t2w...

Big thanks to @sneyers.info for joining the stream and sharing the latest on the JPEG XL. Of the more interesting ideas: If everything stays on schedule and JPEG XL is supported by Chrome, Firefox stable, one year from today we *could* confidently only serve AVIF and JPEG XL for the major browsers

This is not a surprise. Social-democrats have historically always betrayed the labor movement at key points: they sided with national bourgeoisies in WW1 and WW2, provided reformist distraction to the revolutionary mood in the 60s, participated enthusiastically in the neoliberalism of the 90s, etc.

‘The vehicle suddenly accelerated with our baby in it’: the terrifying truth about why Tesla’s cars keep crashing
Elon Musk is obsessive about the design of his supercars, right down to the disappearing door handles. But a series of shocking incidents – from drivers trapped in burning vehicles to dramatic stops on the highway – have led to questions about the safety of the brand. Why won’t Tesla give any answers?

So we now have a new image format, great for web delivery, that is supported in Microsoft Windows, the Apple platforms, Linux distros, Adobe tools etc, but _not_ in the Chrome browser. If you would have told me 10 years ago that this was going to happen, I would have thought you were joking.

How to Add JPEG XL Support in Windows 11
This article outlines how to add JPEG XL image support to Windows 11, enhancing image quality and compression over traditional JPEG. Since Windows 11 lacks native support, users must install an extension via the Microsoft Store or a winget command. Once installed, JPEG XL images can be viewed in File Explorer.

Alban Fichet and I published a method for lossy compression of spectral images, i.e. images with 1 channel per wavelength 🌈. TL;DR: Cosine transform the spectrum of each pixel, normalize by mean brightness and compress the resulting channels using JPEG XL.
