a few tests using `cjxl` (the reference `jpeg-xl` converter) I performed on a 120.7 MB PNG (the Carina Nebula, first photo from the James Webb Space Telescope):
there's 2 main parameters, "distance" (where 0 is lossless and 1 is the least detectable lossy; higher numbers are more lossy) and "effort" (compression effort, where 1 is quick and 9 is exhaustive/very long)
distance 0 effort 9 took 3 hours (obviously this is for a "write once, read many" sort of archival use-case) and got it down to about half of PNG, 67.2 MB; not bad for maintaining lossless.
distance 0 effort 6 took 1m43s, got it down to 75 MB, about 63% of PNG.
distance 1 effort 8 took 3 minutes and got it down to 7.7 MB which is about 1/15th of the PNG.
distance 1 effort 6 took 4s; got it to 7.1 MB... wait, _whut?_ That's... odd. Smaller than with effort 8. Anyway.

All encodings only used 1 of my 128 cores. Whole-image compression of this nature may not be "trivially parallellizable" ::shrug::

defmodule HendricksFormatter do
	@moduledoc """
	This module is a formatter plugin for Elixir's `mix format` task
	that converts leading whitespace to tabs.
	It tries to intelligently determine the tab width based on the most common
	counts of leading space runs in the file.
	It allows additional space characters for minor adjustments that are below the tab width.
	OK, why tabs? Why resurrect this age-old nerd debate again?
	Very simple: It's an accessibility issue:

Materialist Model's Potential Incompleteness

pmarreck>

Is there any evidence that the materialist model of the human body is incomplete?

ChatGPT4>

The materialist model of the human body, often referred to as physicalism or materialism in the context of philosophy of mind, is the view that everything that exists is no more than the sum of its physical parts. This includes the human body and mind. According to this view, all phenomena, including thoughts, feelings, and consciousness, are the result of physical processes and can be explained through the laws of physics, chemistry, and biology.

This model has been incredibly useful in scientific understanding and has led to many advances in medicine and psychology. However, it is not without its challenges and criticisms, some of which suggest that it may be incomplete:
