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.

I think that issues like sexism can have multiple causes. Such attitudes can be culturally constructed and presented to people at a young age through entertainment media and religious teachings and examples set by parents. Though I have also read stuff about potential genetic foundations for such biases, or a sort of pre-programmed reaction to biological realities.

I don't remember the source, just the take-away, which was: since men tend to be physically stronger than women the natural psychological response most people have is to see men as active "doers" with a high level of agency and to see women as more passive "receivers" with a lower level of agency. Baked-in to our perceptions of people is this notion of "he makes things happen" vs "things happen to her." And it doesn't feel like some kind of moral judgment or even a competency judgment (or much of anything really since it is unconscious). But because of this, people naturally see a man as a better leader or task-accomplisher due to the basic perception of greater agency.

This perception can backfire for men too, though. Whenever tragedy befalls a man he is likely to receive less or any sympathy and even be blamed for it, depending on the circumstances, whereas a woman in the same position would be recognized as a victim (even if she actually had a hand in bringing the tragedy about).

I don't have any data on this. It seems plausible though. And, if true, it isn't an easy one to overcome.

Yeah, some interesting follow-up studies would include an image of a very conventionally-attractive woman as a chatbot, vs an image of a much plainer looking woman, to see if hotness gets more pay.

We can also mix genders on that one....hot woman vs plain man. Hot man vs plain woman, etc.

My intuition is that the better looking ones will get more money, regardless of gender, because humans are like that. If we are going to study these things, it would be interesting to know how strong the male-vs-female bias is against the hot-vs-plain bias.

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.

I read the study. The participant group included both men and women. They both paid the bots-with-faces more than plain chatbots, BUT, men paid plain chatbots more than women did, whereas women paid bots-with-faces more than men did.

In terms of paying the male bot more than the female bot, BOTH men AND women paid the male bot more. This echoes results that have been found in past studies about managerial preference, as I recall. The male-favoring bias was shared equally by men and women alike. The common narrative that the gender pay gap is an event of "men holding women back" is not supported by these findings. The better-fitting narrative is that the gap stems from an unconscious bias that everyone shares, regardless of their own gender.

Based on the interviews, the participants didn't realize they were paying the male bot more. They all said gender didn't matter to them. This suggests the bias is unconscious.

This was just one study, of course. Conclusions like this need many more studies with variations in methodology in an attempt to eliminate or control for various non-obvious factors that might skew the results. For example, the people chosen in this study were all working adults (18-65) with knowledge-work jobs. Maybe a similar study in a different field would get different results? Questions like that DO need more studies to answer.

if this were true it would not be possible for the system to read the watermark.

You confuse "invisible to humans" with "invisible to statistical analysis". Humans can't, for example, see the difference between metameric colours. Statistical analysis can. Humans can't see minor drift at scales where Brownian motion dominates. Statistical analysis can. Humans can't see the difference between background disease rates and new rising threats. Statistical analysis can. On and on. Statistical analysis is a far more powerful tool than human perceptual abilities.

this is also a lie. Identical thoughts must be expressed identically, otherwise they are, in fact, *different* thoughts.

I literally gave an example above. If you saw "picked a mango", "selected and picked a mango", "from within the tree, picked a mango", you would never think there was anything going on in the choice, and it isn't going to change the story one iota.

It actually makes RAM needs worse than a dense model, for a given quality.

That said, inference techniques like FreeToken are improving MoE swapping performance, so it's not as bad as it once was. Honestly, I would not be at all surprised if we start doing training in a swap-aware manner, where expert cache misses count as loss and models can queue experts to start loading before they're needed. Could even train in two tiers of loading - RAM and disk. Wouldn't that be great? Could run multi-terabyte models on consumer hardware. Training would tend to tend to concentrate key logic and reasoning on small number of very active experts, mixed reasoning/knowledge on less common experts that are usually kept in RAM, and rarer knowledge on experts that usually remain on-disk until needed.

There are well known, reputable abliterators on HuggingFace.

Also, censorship usually (not always) is something you care about for chats, not agentic work.

A .safetensors or .gguf model cannot run code unless you let it. No agentic framework = all it can do is write text. It can't hurt you directly. At worst, it can only lie to you.
