Decayfmt – a file format that corrupts itself a little every time you open it
- NDlurker 1mo agoShould have patented it and licensed it to Snap
- m3kw9 1mo agoI thought something like this should be part of the file system to make it even more laborious to by pass
- dylan604 1mo agoA company I was at had a disk array that would do something like this. It wasn't a documented feature mind you. During writes, it would randomly zero out data within a file. So at least it didn't get progressively worse, but it was a bear to isolate. These were large media files so a quick look at the head/middle/tail could easily miss the problem areas.
- dang 1mo agoKind of like how human memory works, if I understand correctly.
- yboris 1mo agoA better analogy would be if every time you played the video file, the mechanism hallucinated a little, bringing in your current feelings as input to change the emotional undertones (and possibly characters and events) depicted in the video.
- angeldimitrov94 1mo agoSeems like there is no mechanism to allow non-corrupting reads from authorized processes? Begs the question then of what the point of this is. Pure novelty, or truly something that could be used in practice?
- aravpanwar 1mo agodecayfmt creator here, its pure novelty.
- jolmg 1mo ago> This is a social contract What's the other side of the contract? Why would a reader oblige to corrupt?
- mdp2021 1mo agoProbably satire. Like: "social contract: you will allow fools to choose your government".
- M95D 1mo agoWould you please stop inventing more ways to enshittify the world?
- m3047 1mo agoYou might look into (Norbert) Weiner functions.
- jasonpeacock 1mo agoReminds me of Tie::Hash::Cannabinol: Tie::Hash::Cannabinol is a completely useless demonstration of how to use Tie::StdHash to pervert the behaviour of Perl hashes. Once a hash has been tied to Tie::Hash::Cannabinol, there is a 25% chance that it will forget anything that you tell it immediately and a further 25% chance that it won't be able to retrieve any information you ask it for. Any information that it does return will be pulled at random from its keys. Oh, and the return value from exists isn't to be trusted either :) [1] https://metacpan.org/pod/Tie::Hash::Cannabinol https://metacpan.org/pod/Tie::Hash::Cannabinol
- BugsJustFindMe 1mo agoThis is NOT a file format that corrupts itself. This is a file reader that corrupts files. There's a big difference. Nothing about the format itself causes or requires corruption. A better tagline would be "decayfmt is a social contract enforced by pinky promise".
- aureate 1mo agoDammit! This renders it completely unusable.
- mathgeek 1mo agoTrue, but only a little bit each time you read it.
- serbuvlad 1mo agoBasically what you want is a custom PCIe device that can P2P DMA the DRM-encrypted frame data to GPU DRM-protected memory directly, more corrupted each time. Can still be replayed, but would likely require special hardware to do so.
- gouggoug 1mo agoI came here for this comment. "A file format that corrupts itself a little every time you open it" simply isn't possible. It's almost like the author is ragebaiting with this AI generated non-sense.
- AreShoesFeet000 1mo agothis is genius territory
- aravpanwar 1mo agodecayfmt guy here, people are pressed by a repo that starts its readme with tung tung tung sahur
- fnordlord 1mo agoFrom what I remember, MS Paint do something similar when you would save the image as a jpeg. It would apply the algorithm each save and the image would degrade a bit each time. It was super fun.
- jolmg 1mo agoThat happens with all editing programs for lossy formats, but it's on write, not on read.
- horticulturist 1mo agoThis sounds like Excel when you open a CSV file.
- ricudis 1mo agoI initially thought this would be part of a fuzzer.
- nikolay 1mo agoA virus I wrote in the '90s did just that - every time you opened a file, it damaged a small random part of it. My plan was also to randomly change the digits of numbers when printed on paper. I wrote this because a friend of mine managed to steal my source code during my naive XOR encryption. The "encrypted" files had a bunch of zeroes, and he saw my password. My virus worked. First, it damaged his working copy; then he tried to copy the backup, but in doing so, he damaged it, too, even though he claimed his backup diskette was write-protected. The virus didn't spread because I knew how evil it could be - just as evil as MS-DOS, which would run a hidden .COM file without thinking twice. So many fast typists like me were often mistyping "DIR" as "DUR", so I just put my virus in a hidden DUR.COM, copied it into the empty allocated space of COMMAND.COM (less than 200 bytes), and printed out "Bad command or file name". So, the theft was avenged! P.S. I didn't specify, I didn't have my own computer, only used computers at school and my friend's personal computers, leaving "encrypted" files in case I forgot to bring my diskette. So, after he stole my code and some personal files, her never left me alone on his computer, but he never thought I would infect his computer so easily right in front of his eyes without him realizing it!
- atulvi 1mo agoThe slop is strong on this one
- aravpanwar 1mo agodecayfmt guy here, I was not going to make this without AI eitherway.
