    You are comparing it to a hash, following some extra rules on what the data could be. You have exactly the length of hash before you can reliably count on duplicates (and collisions happen much sooner). In torrent v1, this is SHA-1, which has a 160-bit (or 20 byte) hash. Which means for every single additional random bit, you have doubled the number of possible matches.

    If your torrent has an uncommonly small chunk size of 256KiB, that’s 261,144 bytes. Minus the 20 from above, and you have a likely 256^261124 chunks that match your hash. That’s a number so large that Google calls it infinity. It would take you forever just to generate these chunks by brute force, since each would need to be created, then hashed, then the results stored somewhere. Many years ago, I remember someone doing this on CRC32 (32 bits/4 bytes) and 6 byte files. It took all night, and produced dozens of hash-matching files. You’re talking many orders of magnitude bigger.

    But then what? You’d still need to apply the other rules on what the data could be. Rules that are probably more CPU-intensive than the hash algorithm.

    The one trick that AI might be able to use to save the day is that it may contain in its corpus the original file. In effect, that would make the AI an unlikely seeder.










  • It’s very much the Oracle model.

    A long time ago, Oracle DB could handle workloads much, much larger than any of their competitors. If you needed Oracle, none of the others were even a possibility. There are even tales that it was a point of pride for some execs.

    Then Oracle decided to put the screws to their customers. Since they had no competition, and their customers had deep pockets (otherwise they wouldn’t have had such large databases), they could gouge all they wanted. They even got new customers, because they had no competition.

    Fast forward and there are now a number of meaningful competitors. But it’s not easy to switch to a different DB software, and there are a ton of experienced Oracle devs/DBAs out there. There are very few new projects built using Oracle, but the existing ones will live forever (think COBOL) and keep sucking down licensing fees.

    VMware thinks they are similarly entrenched, and in some cases they’re right. But it’s not the simple hypervisor that everyone is talking about. That can easily be replaced by a dozen alternatives at the next refresh. Instead it’s the extended stack, the APIs and whatnot, that will require significant development work to switch to a new system.

    Not necessarily. They could split the video in advance, assuming the ads will always be at the same point. Even if not, they could still use the direct, unaltered source with a range. The big challenge would be keeping it all synced, which I think is safe to say that they will get right.

    But even if it did need to be transcoded, YouTube automatically transcodes every single video uploaded, multiple times. They are clearly not afraid of it.

    I said nothing of the sort, and have no idea where you got that idea. All I said was that marketing claims are separate from the contract.

    However, this thread is clearly not interested in any actual exchange of ideas or information, so I will no longer be taking part. Go ahead and downvote.

    1. False advertising has nothing to do with breach of contract. Completely separate sections of law.

    2. Nothing offered in perpetuity will stand up in court. You can argue about reasonable terms, but it can never be forever.

    3. Marketing gets you into the contract. The contract holds the actual terms that both (or all) parties are bound to.
