  • but the combat is a bit too hard for me

    I haven’t really played since I was at most a teen so maybe the later battles aren’t actually as hard as I remember, but if this is a bottleneck then OP may find later sections of the game’s main story frustrating. I think the game itself is a good vibe fit and has broadly aged well, but something to keep in mind for OP!





  • It’s a bit excessive for my taste as well. Traditionally if you felt the need to cut this much just to make the sentence come out the way you want, you’d just do another take instead of making this many cuts in post. Over-cutting of spacing also makes the pacing a bit too “word-vomit” rather than “polished” imo.

    I imagine this is more normalized in stereotypically “zoomer” presentation of video content, but it might also just be this guy (or their editor’s) style.





  • I simultaneously believe that Wikipedia is valuable and that it’s not clear that WMF needed $185 million dollars.

    As far as I can tell the situation has not significantly changed since “the last time(s)” this was discussed. Wikipedia remains a valuable resource, and WMF continues to aggressively increase both spending and fundraising revenue. Whether you think that means you should donate or not is probably the same answer as it was several years ago for most individuals based on personal preferences.

    edit: typo





  • This is a genuine question and not a passive aggressive one: why make the submission a link to a social media post when that post is mostly just a link to a news site anyway? (you could include link to or even quote the commentary either in the submission body or a comment if you think it’s a valuable addition)

    edit: has since been answered in another comment orz, I opened this and then was talking to people for a while before commenting






  • I actually think this video is doing a pretty bad job of summarizing the practical-comparison part of the paper.

    If you go here you can get a GitHub link which in turn has a OneDrive link with a dataset of images and textures which they used. (This doesn’t include some of the images shown in the paper - not sure why and don’t really want to dig into it because spending an hour writing one comment as-is is already a suspicious use of my time.)

    Using the example with an explicit file size mentioned in the video which I’ll re-encode with Paint.NET trying to match the ~160KB file size:

    Hadriscus has the right idea suggesting that JPEG is the wrong comparison, but this type of low-detail image at low bit rates is actually where AVIF rather than JPEG XL shines. The latter (for this specific image) looks a lot worse at the above settings, and WebP is generally just worse than AVIF or JPEG XL for compression efficiency since it’s much older. This type of image is also where I would guess this type of compression / reconstruction technique also does comparatively well.

    But honestly, the technique as described by the paper doesn’t seem to be trying to directly compete against JPEG which is another reason I don’t like that the video put a spotlight on that comparison; quoting the paper:

    We also include JPEG [Wallace 1991] as a conventional baseline for completeness. Since our objective is to represent high-resolution images at ultra-low bitrates, the allow-able memory budget exceeds the range explored by most baselines.

    Most image compression formats (with AVIF being a possible exception) aren’t tailored for “ultra-low bitrates”. Nevertheless, here’s another comparison with the flamingo photo in the dataset where I’ll try to match the 0.061 bpp low-side bit rate target (if I’ve got my math right that’s 255,860.544 bits):

    • Original PNG (2,811,804 bytes) https://files.catbox.moe/w72nsv.png
    • AVIF; as above but quality 30 (31,238 bytes) https://files.catbox.moe/w2k2eo.avif
    • JPEG XL could not go below ~36KB even at quality 0 when using my available encoder, so I considered it to fail this test
    • JPEG (including when using MozJPEG, which is generally more efficient than “normal” JPEG) and WebP could only hit the target file size by looking garbage, so I considered them to fail this test out of hand

    (Ideally I would now compare this image at some of the other, higher bpp targets but I am le tired.)

    It looks like interesting research for low bit rate / low bpp compression techniques and is probably also more exciting for anyone in the “AI compression” scene, but I’m not convinced about “Intel Just Changed Computer Graphics Forever!” as the video title.


    As an aside, every image in the supplied dataset looks weird to me (even the ones marked as photos), as though it were AI-generated or AI-enhanced or something - not sure if the authors are trying to pull a fast one or if misuse of generative AI has eroded my ability to discern reality 🤔


    edit: to save you from JPEG XL hell, here’s the JPEG XL image which you probably can’t view, but losslessly re-encoded to a PNG: https://files.catbox.moe/8ar1px.png
