“They tried to bury us. They did not know we were seeds.”

- Dinos Christianopoulos

Remember that one comic I made about Solarpunk, realism, and dystopia? There's a zine version available now! Feel free to print it out and distribute

Thank you to the person who arranged it ✨ all credits listed in the document

@vildis +9001%

Why they don't go with tar or pax or plain bzip2 / xz is beyond me.

@kkarhan @vildis It's legacy stuff from the usenet days. One file being broken allows you to just download missing blocks for it from other usenet providers so that you don't have to redownload the entire thing all over again because one piece is missing/broken on your provider. Most tools these days basically make the rar files essentially transparent anyways, so you never really need to worry about it...?
@jay @kkarhan @vildis you just reminded me of PAR files
@kajer @kkarhan @vildis Yep, still use them to this day (entirely transparently to me).
@jay @kkarhan@infosec.space @vildis right but torrents literally do the block integrity check and redownload as part of the protocol and infohash, with even better granularity. and if you want to seed you have to keep the split rars *and* the unpacked media, so it takes up double the disk space.
@gsuberland @vildis What you're seeing there are people downloading from usenet and just uploading to torrent sites then. There's very little point in uploading split rars to torrent sites as you point out (though there are video apps out there that allow you to transparently play media directly from split rar files) without needing to extract.
@jay @vildis yup, exactly. I know all the scene history, it's just very annoying when people continue to do this. most of it comes down to the idea that it allows you to verify the split rar hashes against the release group's hashes to prove it wasn't tampered with during the reupload, but nobody ever does that anyway, especially on TV/movies, and it's a huge headache.
@jay @vildis there's also a bunch of nonsense people get up to like someone uploading to a private group as a split rar, then another group getting hold of it and doing a public rerelease, except of course they want to bundle their group's NFO with it. but they can't do that without changing the rar hashes and ruining the Purity™. so what do they do? they pack the split rars into a *new* set of split rars, just to add the nfo/diz file. and then someone uploads that verbatim as a torrent.
@jay @vildis so you get utterly ludicrous situations like a torrent of a split rar of a split rar of an iso file and you need triple the disk space free for unpacking if you want to seed.
@jay @gsuberland @vildis
Huh... I've always seen rars as sus and avoided them.
@mian @gsuberland @vildis Not sus at all, just that usenet was a text-only format and the internet wasn't exactly as stable as now so things like PAR files and splitting files for easier transfer/retransfer were needed.

@gsuberland @jay @vildis now I'm wondering if this layering of junk might be by accident helping in one way:

if there's a dozen unrelated torrent uploads of the same set of split rars, and none of them are completely seeded, you may be able to mix and match the rar files from all the partial torrent downloads?

Caution, tangent

One thing I personally benefitted from a lot when it comes to rars, back in the floppy disk era, was the ability to create rars with customizable 5/10/20% redundancy of data so it could self heal a few bad sectors away.

It's a feature I wish more backup/archive tools would have today still.

But that's not at all helpful for any kind of internet downloads nowadays (and hasn't been for a long time).

@gsuberland @jay @vildis same for disk files, which even takes more spaces. i just don’t get why people do that
@vildis @kkarhan Using file sharing hosts for movies is illegal only for the uploader. BitTorrent and IPFS are illegal for the downloader as well, because of how those things work.
(IANAL, but that’s how it works in Germany)
@vildis Okay, .tar.001-.tar.nnn it is then...
@vildis movies should only be distributed as uncompressed jp2k
@vildis I can get behind this campaign
@vildis Don’t forget the RARs with password protection, like who was that for
@MisterMoo @vildis for people who had all the RAR part files, probably the uploader only
@vildis I'm old enough to have split a file across multiple floppy disks. 😅
@TranshumanBlues @vildis I also remember rar's spiritual predecessor, arj.

@vildis Parts were for slow unreliable connections back in the day, so you downloaded them one by one and if one failed you just did that piece not whole huge file. When you had it all, there was integrity check when combined that wouldn't be there otherwise and it would tell you which part was corrupted so you just got that one again.

It wasn't for compression purposes, it was for delivery purposes. No one compresses them these days.

@vildis

But it's 100% spot on and totally accurate 🙂👍

@vildis I had spats with some people over this. I requested them to block rar torrents, they said it's good for saving space! But it saves almost no space when used with video content. I gave up and installed/setup unpackerr

@vildis real use-case for splitting: transferring large files from A to B either over a very crappy network link or via physical media much smaller than the original file. Think diskettes and sub-1Mbit networks over sub-par phone networks.

The problem with pirates is they have a way of doing tihings without understanding why or where that way came from.

TL;DR - Pirates are ignorant at best and could do well to learn their own history.

@vildis It is lovely. Thank you.

@vildis ... compression? rars? ...

do you mean like a house cat?
here, I have your compressed rars.

@vildis One reason for splitting is that JDownloader doesn’t support Mega.nz files above 5 GB. But yes, RAR is the wrong format.

@vildis@infosec Couple of years back I got a work related data dump from an colleague who had sent a multi-part rar across multiple emails.

Once combined, there was a single zip inside, which contained a single data file.

Progress.

@vildis this is only needed for file hosters / the direct download scene
