Vint Cerf Warns Against 'Digital Dark Age' 166

Posted by Soulskill from the strangely-silent-on-digital-bronze-age dept.
An anonymous reader writes: Vint Cerf, speaking at the American Association for the Advancement of Science, said we need better methods for preserving everything we do on computers. It's not just about finding better storage media — it's about recording all the aspects of modern software and operating systems so future generations can figure out how it all worked. Cerf says, "The solution is to take an X-ray snapshot of the content and the application and the operating system together, with a description of the machine that it runs on, and preserve that for long periods of time. And that digital snapshot will recreate the past in the future." Cerf is also pushing for better data preservation standards: "The key here is when you move those bits from one place to another, that you still know how to unpack them to correctly interpret the different parts. That is all achievable if we standardize the descriptions."

      Part of my old job (in a museum Exhibits department) was upgrading interactives and videos from the 80s and 90s to modern equipment - that included "transferring" laser discs the old fashioned way - plugging one of the still-working players from the floor directly into the capture hardware.

      The thing is, I was transferring LD to DVD, which is actually a step *down* in quality. Kind of but not quite like how VHS is a step down from Beta (which I also dealt with).

      The great thing about standards is there's so many of them!

      • You must have been using a sub-par encoder then. A single layer DVD disc usually allows a significant step up in quality compared to what you would get with an LD disc.

      Well, luckily the trend has been away from tying one specific format to one specific media. Instead of the Audio CD you can have an MP3/OGG/AAC file that'll play from a HDD, SSD, USB drive, burned to a CD, DVD, BluRay, stored on a tape and so on. That eliminates the need for ancient equipment and media. Of course that doesn't really make it any easier for a time capsule, but the way to preserve is to copy forward.

      • A long and twisty conversion path. Just like with Microsoft. You need Word for Windows 2.0 to read the Word for MS-DOS files. You need Word for Windows 6.0 (Office 4.3) to read the Winword2 files. You need Office 97 to read the Office 4.3 files. It's even worse with Apple, because they can.
