  • I hate that this has become so commonplace. Yes for some - mostly physical - things it’s much better if you can see someone do it. But finding an obscure setting in an app shouldn’t be a video.

    Stuck on a 20 step installation process? Here’s a 10 minute video showing all the steps you already know before the phase you’re stuck. Sure you can scrub through it, but it’s still faster to skim and scroll through a text with images.





  • “And while Spectral JPEG XL dramatically reduces file sizes, its lossy approach may pose drawbacks for some scientific applications.”

    This is the part that confuses me. First of all, many applications that need spectral data need it to be as accurate as possible. Lossy compression in that might not be acceptable.

    More interestingly (and I’ll read the actual paper for this): which data will be more compressed? Simply put, JPEG achieves its best compression by keeping the brightness but discarding colour. Which dimension in which spectral space do the researchers think can be more compressed than others? In this case there is no human visual system to base the decision on.
