Today’s XKCD comic comments on digital preservation in Randall Munroe’s usual style.
The second panel shows slight degradation, as if saved at a low-quality JPEG setting; I can see it only in the Photoshopped version. The third one is obviously blurry and has some icons at the bottom. The last one looks like a very crude screenshot, watermarked as made with unregistered software. The hover text says, “â€œIf you can read this, congratulationsâ€”the archive youâ€™re you're using still knows about the mouseover textâ€!” Yes, those weird characters you’re seeing are in the original.
It’s a good reminder that preservation involves more than just having the file at hand.
