  • It’s interesting to see people who either weren’t educated on a topic or maybe didn’t really grasp its usefulness converge on the same solution.

    I wonder if this author continued developing this method or if they were pointed towards some calculus and statistics textbooks after sharing this paper.







  • Lol back when games were simpler, they were harder because one of the few ways they could make a game harder was to reduce the amount of leeway you had from needing to do pixel perfect moves.

    Plus a lot of older games didn’t even have save points, so you either beat it in one sitting, left it on and hoped the power didn’t go out or no one else wanted to use the system.

    Oh and arcade games were often tuned to let you have fun for a bit then suddenly get way harder so you’d lose and need to put quarters in if you didn’t want to start over from the beginning and ports to consoles often kept these mechanics. I remember noticing the pattern in mortal Kombat, where I wasn’t very good at the game (in hindsight) but could consistently win one match only to lose the next one, continue and repeat until I ran out of continues.


  • 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.

    Edit: Correction: m-disc BDXL 100GB discs are pretty expensive, now that I’m looking deeper. 100 CAD will get a 25 pack of 25GB discs, 50GB discs are a little more than twice that and 100GB are a bit more than twice the 50GB.






  • Yeah, though it has that issue with data density. The denser the data, the more likely it will become degraded from erosion or chipping.

    Also if there’s a discontinuity between our civilization and a future one, the denser the data, the less likely any future civilization would discover it’s there, even if it still has enough integrity to be read.


  • One other possibility that just occurred to me is to encode it into living DNA along with better error correction mechanisms so it doesn’t mutate. Like thinking from a “leave data for future civilizations to find” perspective, though it could also be a decent long term passive(ish) archival. Maybe completely passive if a self-sustaining but isolated environment could be created for it.

    Not great for data you want to keep but also actively use, though. Or data you want to be able to modify.


  • Even with jpeg, you only lose data each time it’s encoded. If you save the file instead of taking a screenshot, the quality remains the same.

    That said, I don’t know if there’s a digital storage method widely used that will last longer than a book without some sort of active aspect to the storage (like copying the files to a new medium every now and then).

    I think punch cards are one that can, but they aren’t used much anymore due to poor density and speed, plus being susceptible to literal bugs. It’s possible to encode digital information into carved rock, but that would also have density issues (higher density means less reliability because the amount of damage required to make it unreadable is lower).

    I think there’s a good chance that a lot of the knowledge we have today could be lost entirely if civilization collapses to a certain degree just due to how we store it.
