[xkcd 1683] Digital Data

That seems to imply everything you're willing to pay for would still be accessible. That's just not the case I think. Things dissappear full stop, also if you do want to pay for it.

A lot of non super popular, not very internationally known media eventually disappears into non-accessible copies in private collections: hard drives, non public accessible computers etc and at the same time becomes nearly impossible to purchase or otherwise retrieve online. For example public broadcasters in Europe: they don't want to put in the money and effort to preserve their entire archives, they don't make everything from the past accessible, things do get lost in their archives (sometimes as a conscious choice) and at the same time it is illegal for private people to archive it... until it is too late. For example lots and lots of radio plays are probably already lost forever.

You mean we should consider recording information on silicon?

That feel when you find ancient media circa early 2000s and it's all pixelated to hell on newer displays. And then you see they're from long-dead sites like the OG failboat and icanhazcheeseburger etc. You saved them in full-fat png for some reason but it doesn't matter. Still looks like shit. And they're 10 years older than your dog who is wobbling up to you this morning. Her face is greying. Stiff and old. Just like you. Time's a bitch.

Ah nice. That's already on my list. I did see the Netflix series.

Isn't DNA, like, famous for its mutations?

I want my journal to die with me. It's got a lot of painfully honest stuff that could hurt the people I love.

Perfection. But we could deep fry it a bit.

I really hope the Internet Archive survive their lawsuits. They're important not just for archival of websites (the Wayback Machine) but also of books, audio recordings, etc. There's a large amount of old content that's only archived at the Internet Archive.

You could archive a description of the file format alongside the files. Maybe a pseudocode implementation too, or actual code (although who knows which programming languages will exist 300 years from now).

Or the dreaded .doc and .xls that even Microsoft has problems with today.

The US Library of Congress recommends archiving data in SQLite databases, since it's a simple, well-documented format, SQLite is public domain, and SQLite devs have promised to support it for a long time and retain backwards compatibility indefinitely.

CSV and TSV are okay too of course, but it's often much easier to deal with large datasets if they're in an actual database format.

There's M-discs which are supposed to last for 1000 years, but obviously nobody has fully tested that yet. They're readable by normal DVD and Blu-ray players and go up to 100GB capacity.

There's LTO tapes as well of course, but they're not rated to last for as long (only 30ish years).

Oh thank you for telling me about these, I wasn't aware that there was a DVD/bluray format designed for archival purposes. The media is more expensive than I remember blank discs being back when I still used them, but it's not horrible either, like $100 CAD for a 25 pack.

It's probably too late by now for my old backup/data CDs and DVDs, but this is the first time I've felt like I could be confident in something to store data that I want to archive without worrying about doing the active archival stuff with (and where the files won't be stored on someone else's computer, putting both my privacy and data security in their hands).

It's also given me a good reason to get a drive capable of reading those old data discs to see if I can even access that data still, though I'm not holding my breath. The writers aren't even that expensive.
