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.

Avif encoders have seen a lot of improvement in the last few years, jxl encoding hasn't improved much since everyone has been focused on the decode side. There is plenty of room for encoder improvements though.

> 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...

No, base frequency = lowest frequency. Many of the harmonic overtones are just higher octaves (2x, 4x, 8x the base frequency) so they would point to the same note though.

001

Jon Sneyers @sneyers.info · 14/03/2026

I'd say base frequency is what the note is. What octave it appears to be in can depend on relative amplitudes of the overtones though.

"High fidelity DNG" does indeed sound like DNG 1.7 with a slightly-lossy jxl payload. If it's lossless, there's no need to talk about fidelity, and if it's lossy, it's either lossy JPEG or lossy JXL, and arguably lossy JPEG cannot be called "high fidelity" in this context since it's only 8-bit.

PNG is quite good at this because the patterns are repetitive so the DEFLATE method PNG uses will be effective. JXL can in principle also work well but currently the libjxl encoder is not great at using lz77 effectively by default. Can you try with cjxl -d 0 -e 9 -P 0 -I 0 --patches=0 -g 3 ?

Jon Sneyers @sneyers.info · 22/02/2026

These halftoning patterns are tricky for lossy codecs since there's so much high frequency signal. If you would have a greyscale version where colors are continuous, both lossless and lossy would work better.

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

E.g. on racism/migration, utopian socialists mostly try to convince people that racism is just morally wrong, while marxists will focus on the need to avoid working class division and to build solidarity.

000

Jon Sneyers @sneyers.info · 12/02/2026

What you're pointing at is related to the difference between marxism and utopian socialism. For utopian socialists, the way to achieve socialism is through moral persuasion. For marxists, it is through the enlightened self-interest of the working class.

What exactly do you need? The container is optional in jxl. If you want to create some examples with container, you can use cjxl --container=1. Or just use an input image with Exif or XMP metadata, which will force using the container.

Jon Sneyers @sneyers.info · 23/07/2025

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.

Jon Sneyers @sneyers.info · 15/07/2025

Lossless float is not something libjxl has been particularly tuned for. More accurately: besides checking that it works, not much effort has been spent on getting it fast or well-compressed. I don't know how much room for improvement there is.

Bij elke "optimalisatie" is de vraag of hetgeen geoptimaliseerd wordt eigenlijk wel datgene is waar de wereld beter van wordt. Vaak is dat niet het geval. Zie bijvoorbeeld ook "fiscale optimalisatie" of in de academische wereld: epsilon-incrementele publicaties om publicatiecijfers te optimaliseren.

In this case, I think the main question is why academics would be tempted to cheat (either as author or as reviewer), and how we could reduce/remove those incentives.

000

Jon Sneyers @sneyers.info · 06/07/2025

That was not my point, but I don't agree it's always a bad argument. Sometimes things are broken beyond repair and it's better to replace them with something better than to keep applying band-aids and pretending things will be fine.

Jon Sneyers @sneyers.info · 06/07/2025

IMHO, unreasonable publication pressure — mostly caused by research funding guided by neoliberal principles and the widespread conflation of "objective and fair criteria" with "quantitative metrics" — has already seriously compromised peer review and academic publishing in general.

TBH, I prefer returning a bool (where true is OK and false is failure), and using some other way to signal which error condition it is, if there's a need for that. Usually just OK or not OK suffices, and calling the function in an if-else or if(!foo), without a return code variable, is convenient.
