1392Retraction: The App Store Rejection of the Week That Was a Correct Rejection68345“> In an uncomfortable exchange between Beher and Godier on Bluesky, Beher pointed out that Godier’s Dark Hours had the same bug as Beher’s that routed people to “random fields in Mexico”.
Stealing an open source repo and launching it as your own app is a brazen move. Launching it with the same name as the original repo is just flagrant.
This guy thought he was going to ride this controversy to some free publicity for himself, using other people’s work. He flew too close to the sun and got caught out on every level.” — Aurornis

1492Scientists discover Kelvin-Helmholtz Instability on the surface of the Sun63303“This kind of observation is a big deal for solar physics.
It's been believed for decades that these small-scale (~100km and below) turbulent features are critical to understanding how energy dissipates in the Sun. And thus, how sunspots and flares form.
The subject has been very qualitative but is yielding on both observational and simulation fronts. I worked adjacent to this area from the 1990s-2010s, and it had been true that MHD numerical simulations of significant volumes of the Sun (but at a scale fine enough to resolve these features) were not possible. That has obviously changed!
Additionally, it had been that the best solar observatories could not quite resolve these features. In the late 1990s some of the best images came from a couple of observatories in the Canary Islands (e.g., the 1-meter Swedish telescope -- https://svs.gsfc.nasa.gov/4715/). The spatial resolution was perhaps in the ~100km range.
Of course, these are absolutely mind-boggling images. You're looking at a slice of the solar photosphere that has a temperature such that it activates a spectral line around 400nm. By isolating that wavelength, we can see what's happening at that temperature, and thus, sample a slice of the photosphere.
So, that had been the state of affairs. Now DKIST (4m aperture), with the particular instrument highlighted in OP, appears to be at a spatial resolution ~5x finer than the above imagery -- see Fig. 1c in the Nature paper (https://www.nature.com/articles/s41586-026-10871-3). It appears also (https://dkist.virtualsolar.org/vanNoortfastcam/) to be observing at 740Hz (!) for speckle reconstructions at ~1Hz.
At this scale, vortices of the flow are well-resolved -- where before you just resolved the convective cells but not the turbulent features around them. It's these turbulent features that are transporting energy.
To contextualize with respect to a HN perennial topic: DKIST (commissioned 2021) is funded by NSF, from the same pile of money that once funded Arecibo (up to 2020).” — mturmon

63303NASA figured out how to keep its Voyager 2 probe running for another year82380“I ran a few research tasks at JPL, small dollar studies.
We'd often recruit part time work from engineers around the lab through informal networks, (instead of the official channels that segment by "specialization").
One year, one of the developers on my task was the apparently last person who could encode the command sequences for Voyager 2 (hoping memory serves me correctly - event though it was only 8 years ago). She would occasionally come late to meetings because they were dealing with some trouble with the old satellite.
Pretty amazing how little is set aside for these projects that most the staff keeping it alive have "day jobs". I hope she's still uploading” — jvanderbot

82380H3-metal – Native MiniMax-H3 inference for Apple Silicon62293“I've been using MiniMax H3 on my M5 Pro 64GB MacBook Pro through ComfyUI. It works extremely well.
I had to modify the default ComfyUI workflows to use a GGUF quant (city96's ComfyUI-GGUF custom node, UnetLoaderGGUF in place of the stock loader) [0].
I use the model labeled Q5_K_M. There is Q8_0 available as well, which is 34GB and fits fine in 64GB unified memory if you keep resolution modest.
The main issue is speed, a ~9-second 480x864 clip at 20 steps takes me a bit over an hour. So this will be cool to try for the speed up alone.
There's a lot of great information and workflows available to follow on the r/StableDiffusion subreddit.

https://hackaday.com/2023/04/02/spy-on-your-cat-to-make-sure...
His exercise routine is somewhat variable but he usually goes for a short jog a few dozen times a day. Most often at 5 am, for whatever reason.
Since the article I also built and hooked up a treat dispenser for extra motivation.” — SyzygyRhythm
