And that's besides asking people who mostly live around and beyond the polar circle to make decisions for the rest of us.
Same goes for those living near the equator.

Have fun living with winter depression (and depressives driving around you) for half a year.
Or getting ZERO sleep in the summer. It's gonna be great.

But hey... As long as you don't have to suffer the tyranny of setting the clock twice a year. That's what really matters.
Razor blades are cheap. So is rope and simply swerving into oncoming traffic.

Slashdot doesn't have table support, so it's hard to do side-by-side well, but:

JPEG XL advantages:

Licensing:

JPEG XL: Fully royalty-free (Open source / Apache 2.0)
HEIC: Proprietary patent minefield (MPEG LA, Advance, Velos; royalties apply)

Legacy JPEG Migration:

JPEG XL: Lossless, reversible bitstream transcoding (~20% smaller); fast enough for real-time web servers
HEIC: Lossy re-encode only (generational quality loss; cannot reconstruct original JPEG)

Fine Detail & Textures

JPEG XL: Retains sharp text, fine lines, subtle textures, and film grain
HEIC: Video-derived coding (HEVC / X.265). Tends to smooth out high frequences and smudge grain.

Software Encoding Speed

JPEG XL: Extremely fast; highly parallelized SIMD architecture
HEIC: Exceptionally slow and computationally expensive in software

Software Decoding Speed

JPEG XL: Fast, lightweight multi-threaded CPU decoding
HEIC: Heavy CPU overhead (without using hardware acceleration)

Progressive Rendering:

JPEG XL: True progressive decode; smart saliency algorithm to focus bandwidth on critical details first.
HEIC: None; full file must be received and decoded before display

Lossless Compression
JPEG XL: Dedicated modular mode; vastly outperforms PNG and WebP
HEIC: Ill-suited; you basically have to try to do lossless compression with an inherently-lossy format

Bit Depth & HDR

JPEG XL: Native HDR; up to 32-bit floating point per channel
HEIC: Typically capped at 10-bit or 12-bit integer

Max Dimensions & Scaling

JPEG XL: Up to 1B x 1B; efficient viewport/crop loading without full decoding
HEIC: v5.2, 4096x2160; v6.2: 8192x4320; a tiling hack allows up to 16384 x 16384

Channels & Color Spaces:

JPEG XL: Arbitrary color spaces (hyperspectral); unlimited extra channels (alpha, depth, thermal, masks, CMYK, etc)
HEIC: Rigid container; limited auxiliary channels and standard video color spaces

HEIC advantages:

Rollout / acceleration:

JPEG XL: no dedicated hardware acceleration (thankfully, it's not as important because it's so much more efficient). Software adoption still rolling out.
HEIC: Hardware silicon (ASICs). Default capture format on modern iOS/Android; native capture in Sony, Canon, and Nikon cameras

Video:

JPEG XL: Supports animations (GIF/APNG replacement), with some optimizations** (it's not just a series of stills), but lacks the full set of optimizations that a proper video codec has.
HEIC: Container naively pairs full HEVC video tracks and audio with video.

** - JPEG XL can store up to 4 reference frames in a buffer, with multiple blending modes from the references (add, replace, multiply, etc); has subframe bounding boxes ("dirty rectangles") for when only part of a frame changes; invisible frames; modular deltas (differences between frames); etc. However, it lacks motion vectors (e.g. detecting a feature drifting across a scene and simply having to encode "move it" (followed by any needed deltas). So it's great for "GIFs", but if you wanted to encode a full movie, it'd be significantly larger than e.g. HEVC.

Look, I use HEIC, but JPEG-XL is just better.

* Royalty-free
* Lossless transcoding of legacy JPEGs to immediately reduce their sizes by ~20% (fast enough that you can have webservers do it in realtime)
* Better fine detail / high frequency data representation for the same bitrate. HEIC was designed for video and simply is not as good at stills.
* Faster decoding
* MUCH faster compression
* True progressive decoding - and not old-school blocky progressive decoding, but using a smart algorithm that restores coarse detail (particularly focusing on parts of the image that the eyes immediately focus on) first, then progressively adding in finer detail that the eyes take more time to notice later.
* Vastly better lossless compression
* Better colour depth and native HDR (up to 32 bit per channel)
* Up to 1B x 1B pixel images (again, useful for scientific and engineering applications), with efficient loading (don't have to load and decode the whole 1B x 1B image at full resolution to view it)
* Arbitrary colour spaces - you can even use it for scientific hyperspectral imaging. You can include e.g. alpha, depth maps, thermal data, selection masks, etc etc.

It's just a better format for stills. It's annoying that it's taken this long to get support to take off (because it takes ages for most people to update their browsers), but I'm really glad that it's starting to.

Comment Re:mostly mash-ups of existing techniques (Score 2) 106

If the mathematicians ever used ChatGPT to talk about math, then that is the source of the results. LLMs, by definition, cannot usefully contribute to anything that requires more than rearranging existing data. Rearranging existing data is their only function.

What does "anything that requires more than rearranging existing data" mean? Can you provide an example of an information processing device that does more than this?

Oh FFS.

This "private army intimidating people" is nothing of the sort. It is the administration doing EXACTLY what the 1996 law requires of it. The fact that everyone just ignored the law for 30 years does not make Trump the criminal now and it does not make what ICE is doing illegal. It makes what everyone did from 1997-2020 the CRIME.

If you don't like immigration law - then win enough elections to change it. What Bush did, what Obama did, what Biden did on the subject were actual crimes. My gwd DACA - holy crap an entire program made up entirely by executive whim based on wild interpretation of a few line in the code. Wow that honestly sounds a lot like what everyone accuses this admin of doing when it comes to things like tariffs. Funny how we only have laws when the LEFT does not like what President is doing, when the RIGHT does not like it miraculously the courts are unable to find any legal standing, and the legislature decides it has to play its constitutionally assigned role...

What is missing from the entire conversation right now is Trump is governing pretty much EXACTLY like Bush, Obama, AND Biden did. The attitudes about authority and rule making all the same. Even the rhetoric, anyone remember "bitter clingers", once again the real difference is nothing other than who it is directed toward.

The truth is their is no actual air between the leadership styles of Obama and Trump, the real reason he gets so much hate is because the opposition's heroes are opposite sides of the same coin.

Comment Is streaming still a thing? (Score 1) 58

I used to think game streaming was just stupid and wasteful yet in a way this now makes sense. Nobody can afford hardware because massive corporations are hoarding everything while other massive corporations rollback production in order to cater to massive corporations while intentionally exacerbating supply shortages.

With hardware now out of reach those same corporations to get to turn around and offer the plebs a "deal" of a lifetime to pay more for the privilege of renting games by the hour.
