Once you hit ten yeats... all bets are off. Now with scanning in those slides, I'd just toss them into 'photoprism' and let it classify them for me. Will it be perfect? No, but it did a decent job on my 70,000+ images I tossed at it. Took a few days since I don't have NVidia CPUs to run the classifier on for a speed up. But it did a neat job. And it even find obects as well. Very cool stuff.

The problem is one of organization. Let's imagine you get these all scanned in, now you've got +/- ~19,000 pictures to sort.

Re: M-DISC 1000-year DVD and Blu-Ray

If anyone is looking for an external optical drive that can handle blu-ray and M-DISC, then this is the model I endorse: https://www.pioneerelectronics.com/PUSA/Computer/Computer+Drives/BDR-XD08UM… I've been able to read all kinds of blu-rays with it, including UHD. It also uses USB-C which saves so much trouble finding the right cable. And no drivers necessary for running on Linux! Optical media is increasingly uncommon these days, so I can understand why almost no new computers come with them, however external optical drives still have their uses. I've definitely gotten a lot of use with mine with all of the movies I check out from the library! - Josh On Fri, Jan 27, 2023 at 5:48 PM John Stoffel via WLUG <wlug(a)lists.wlug.org> wrote: > >>>>> "Jon" == Jon \"maddog\" Hall via WLUG <wlug(a)lists.wlug.org> writes: > > > In 1975 I was working for Aetna Life and Casualty in Hartford, > Connecticut.

In 1975 I was working for Aetna Life and Casualty in Hartford, Connecticut. At that time Aetna was the largest multiline Insurance company and also the largest commercial user of IBM equipment in the "Free World" (which goes to show that with enough qualifiers you can be the best of anything). In any case we had 500,000 12" magnetic tape drives on site, with another 100,000 in a salt mine for "long term storage". For those tapes the "retention time" was 9999 years. Some of the older tapes were marked as seven-track, 128 bits-per-inch. I asked my boss about trying to read those tapes, and he assured me there was a seven-track tape drive stored along with the tapes, wrapped in bubble wrap. "Yes", I said, "but where is the computer that can attach to that tape drive, and the OS that can drive the tape controller, and the operator that can boot and run that operating system?" My boss put his finger to his lips and said 'Shhhhhhhhh". md On Fri, Jan 27, 2023 at 1:39 PM Chuck Anderson via WLUG <wlug(a)lists.wlug.org> wrote: > Ignoring the 1000-year hype, I think it all depends on how much the > archivist community adopts the technology.

Re: M-DISC 1000-year DVD and Blu-Ray

by Chuck Anderson

Ignoring the 1000-year hype, I think it all depends on how much the archivist community adopts the technology. If archivists decide that M-DISC is a good solution, then the technology to read them will be kept alive for that purpose at least long enough to copy the data to a future format for the next span of time. If that is 30 or 50 or 100 years, you are already doing much better than other types of digital media at this storage density. Luckily M-DISC is just standard Blu-Ray at the physical layer. All Blu-Ray drives can read M-DISC media, and all Blu-Ray writable drives can write to M-DISC media. The same is not true of writing to M-DISC DVDs--apparently some DVD-R drives do not have a strong enough laser to write to M-DISC DVD.

Re: M-DISC 1000-year DVD and Blu-Ray

by Frank Sweetser

Let's be honest - if you gave someone a BlueRay disk *today*, there's a pretty good chance they'd have to go hunting around to find some hardware to read it. 1,000 years from now, you'd have to: - Set up the appropriate laser hardware to scan the physical medium at the appropriate resolution, frequency, etc, while not going so high power that you damage the disc. - Translate the physical pits on the disc to a bitstream. - Translate the bitstream as a filesystem data. - Translate the contents of the files (anyone still have a copy of Word 95?) This technology is probably fantastic on a scale of a few decades, so long as you're careful about which file formats you pick, but if you're serious about centuries or more you'd probably have to stick to something that requires no technology to read, like engravings on glass or non-corrosive metals. (For extra fun, just imagine the fun in a few centuries when amateur archeologists try to figure out these funny markings that turn out to be QR codes https://monuments.com/store/headstones-accessories/living-headstones-qr-code ) On Fri, Jan 27, 2023 at 12:01 PM Tim Keller via WLUG <wlug(a)lists.wlug.org> wrote: > Here's a question... in a 1000 years.. will you even have a drive that > could read such a disk? > You'd need to store details manuals with how to construct a drive and the > format of the disks. > > On Fri, Jan 27, 2023 at 11:55 AM John Stoffel via WLUG < > wlug(a)lists.wlug.org> wrote: > >> >>>>> "Chuck" == Chuck Anderson via WLUG <wlug(a)lists.wlug.org> writes: >> >> > Last night we were talking about long-term storage media that won't >> > degrade or fail.

Here's a question... in a 1000 years.. will you even have a drive that could read such a disk? You'd need to store details manuals with how to construct a drive and the format of the disks.
