    My jaw hit the floor when his reply was "Well, this isn't exactly an atom bomb...." That's why the lawyers are winning right now. It's not because they're smarter. It's because they are SO good at twisting things around, and us geeks can't speak in public worth a damn.

      Also, is there any way to list metrics of exactly what people are downloading via BitTorrent? If there isn't, it's only an opinion that BitTorrent is used primarily for copyright violations.

I myself has ADD and I know a lot of ADD/ADHD persons who are geeks AND goth/industrial/punk..

      AS people (AS=Asperger's Syndrome) tend to be superhuman geniouses in a few narrow areas while ADD/ADHD people tend to be theoretical almost-geniously experts in a wide range of subjects.

      Our (me and my fellow ADDers) problem is that we are so easily bored and when we see the finish closing in we already finished the project in our head (the only thing left is to actually implement it) and the mental energy runs out and we have to move on to something else so we don't get a deep depression. Repetitive work (such as implementing on the computer the stuff you already implemented in your head) causes depressions..

      The reason ADDers are overrepresentated among subcultures are that our way of thinking and making conclusions differ quite a lot from non-ADDers. For example we skip the little details called norms, principles, culture, traditions, etc and go straight to the root matter of the current subject. That's why a lot of us don't feel that we fit in and search alternative lifestyles that fit our minds better...

      People with ADD and AS can be the biggest resource for a company that they can possibly get. You just have to rethink and adjust the internal politics a little. A single interested ADDer can do 10 persons work in short time. You just have to make sure that someone else take over when it gets repetitive and move the ADDer to another project that he/she shows interested in.

  3. Cohen didn't invent multi-source downloading by Sanity · · Score: 5, Interesting
    The article seems to imply that Cohen invented multi-source downloading, for example:
    Cohen realized that chopping up a file and handing out the pieces to several uploaders would really speed things up. He sketched out a protocol: To download that copy of Meet the Fokkers, a user's computer sniffs around for others online who have pieces of the movie. Then it downloads a chunk from several of them simultaneously. Many hands make light work, so the file arrives dozens of times faster than normal.
    Yet this feature has existed in other P2P applications for years.

    Personally I think BitTorrent's core advantage over other file sharing technologies is also its core architectural weakness, namely its centralised nature. This allows an editorial filter on content made available through BitTorrent, yet also makes a juicy legal target. Until recently BitTorrent's obscurity has protected it, but clearly this is no-longer the case.

      BitTorrent is a good application, I'll give you that. But it really is just a first-generation application, and should be seen as such. Packet-bartering should be changed to favor those who seed, and if at all possible, priority should be given to giving packets to those who only need a few more to finish their download (since connections slow near the end).

      It's great, but it needs improvement.

      BTW, how long do you think it will be before bittorrent-style downloads become standard in web browsers and web servers? :) I mean, heck, how hard could it be to write such a browser plugin and server plugin? The server plugin would simply need to create torrent files for each actual file that you're wanting to serve as a torrent (and upload those instead), whole the browser plugin would need to first download the torrent and then show the bittorrent download progress (leaving the window open past the end of the download without an option to autoclose, just like regular bittorrent clients)

      It seems that such a feature would make it a lot easier to run a file server on limited bandwidth.

      Also, while I like the concept of the file finding mechanism not being part of the file exchange mechanism itself, as in BitTorrent, we really need a decentralized way to locate and moderate files - some sort of distributed web of trust, perhaps. Of course, those sorts of things are always a pain to try to catch hacked clients, so I'm not surprised that we haven't seen any good ones.

      Oh, and last on my distant-future wishlist: A financial-incentive packet bartering priority boost. I.e., anyone can download, but if you contribute money to the authors of the content you're downloading (this would require a centralized server, no way around it), you get a faster download rate. The more you contribute, the faster your downloads go; your donation distribution could be handled automatically.

  10. Why isn't BitTorrent defeatable? by saddino · · Score: 4, Interesting

    Here's something that I've been wondering:

    I haven't looked at the source, but given the broad description of the protocol I'm assuming each "chunk" has a GUID along with the payload. Obviously, this allows for swarming and reduced download/upload bottlenecks, but doesn't it also allow for easy corruption of the data stream?

    For example, when the RIAA tried to defeat Napster by brute force, namely setting up drone/honeypot PCs with libraries of corrupted files, the method failed miserably. I would guess that by its nature, knowing what IP you were downloading an entire file from, it wouldn't be too hard to filter out known RIAA servers.

    But, with BitTorrent handling the gathering of chunks from the swarm from multiple IPs, doesn't that greatly increase the likelihood of success for a similar attack?

    For example, shouldn't the MPAA be able to download the source code and modify encoding so that if (Random() % 1000) a chunk flips some of the bits in the payload? Wouldn't installing this code on a farm of drones eventually "corrupt" the datastreams on BitTorrent?

    Or are their safeguards in place for this kind of attack?

      Yup - each 'GUID' for a Bittorrent block is an SHA1 cryptographic hash. If you find a way of generating collisions for those, many computer scientists and mathematicians would love to know. ;-)

      From the FAQ:
      BitTorrent does cryptographic hashing (SHA1) of all data. When you see "Download succeeded!" you can be sure that BitTorrent has already verified the integrity of the data. The integrity and authenticity of a BitTorrent download is as good as the original request to the tracker. Checking the MD5/CRC32/other hash of a file downloaded via BitTorrent is redundant.

      I gather that if a client was pumping out corrupt blocks, or if they were corrupted at some point during transmission, they'd simply get dropped and re-requested. No idea if there's anything to permanently ignore a client that's pumping out nothing but junk, though - but on a busy tracker, it would get drowned out by all the others. Anyone know?

      Incidentally, is anyone else worried by the way the article concentrated on the distribution of television shows, almost to the exclusion of everything else? I've used Bittorrent quite a bit, but only ever for completely legal purposes - plus, I've always thought of it being a rubbish way of distributing dubious stuff, what with IP addresses of everyone downloading available straight from the tracker to whoever might be investigating...
