  • to really hammer home this “many ways to hide”: the PDF is kinda just like a container… it contains other things like images (the patterns for example)… these patterns are probably vector graphics (made up of lines rather than pixels)… this means you can magnify them basically infinitely… and they can contain transparent lines and all sorts of things. they could easily embed that same text in the SVG image, at tiny scale (less than a pixel at 100% scale), and make it transparent… no PDF editor is going to touch the image data: it simply doesn’t really understand it to that degree - it’s an image; not a PDF after all… so that information will remain even after you’ve removed all visible/reasonable marks

    this is just 1 example of practically infinite places it could be - and remember, this text is just lines in an image! it’s not like you can ctrl+f for the text necessarily… you’d have to go through every image manually and inspect every single line, and even then there are no guarantees (perhaps they encoded that information like morse code in bumps in some lines that are only barely visible at 1000% magnification)






  • the thing that everyone always glosses over is that jellyfin should not be run on a public network. it has known security vulnerabilities… that includes VPN remote proxy, so now you have to have external users on your actual VPN, and if that’s the case then plex will work fine because it’s “local”, and has a lot more features

    (and my main issue: media segments don’t work on swiftfin)

    if you’re taking about charlie kirk with that “civil conversation” bit, those conversations were using misleading half truths to publicly debate people he disagrees with in order to convert the people around said debate to his cause. i wouldn’t call that civil… civil is healthy, truthful debate on the merits: not winning at all costs






  • apple silicon has specific changes to amd64, and some extra instructions to help with x86 translation afaik (1 of the main things i think is how memory is laid out is different somehow? so every memory access needs extra clock cycles to accomplish in standard arm64)

    but in general, rosetta2 is incredible: very little performance loss… i thiiink it’s something like 2-10%, which is made up for by the cheaper cores

    from what i understand, graphics is more of a problem… metal just isn’t well supported - i think the standard thing is you have to do direct x <-> dxvk <-> vulkan <-> moltenvk <-> metal, which is a huge overhead and is far from perfect in its translations
