  1. Re:Sue users and scare away the rest on Examining Bittorrent · · Score: 1

    Well, I can be a peer on the ed2k network, but not share any copyrighted files. :) I would simply sit online 24/7 and connect with peers on Kad. New users would connect to me and I would connect them to the network. What they do after that is of no concern to me. ;) Currently ed2k servers keep lists of files shared by clients connected to them, so it can be said that they are contributing to infringement. However, if one neither shares, nor downloads anything, just helps people connect to Kad, he can be relatively safe from **AAs.

    No, the Kad architecture of ed2k is quite safe. There are still issues - namely lack of 100% anonymity and privacy, as well as poorer ed2k performance for new releases (as opposed to BitTorrent and its flashcrowds), but the network itself is quite safe now.

    You have a large list of known clients. You try to connect to them and when you connect to one who is online, he gives you enough up-to-date IP-addresses of other online users. It's very unlikely that all your IP-addresses become invalid (only if **AA manages to sue most P2P users into submission and scare away the rest). And even then, it would only require one IP address of a currently connected user (that you can get on a forum, on an IRC channel, etc.) to get back on Kad (where you would connect with more users and again collect more working IPs for the future).

    I am not sure whether the eMule client comes with a built-in list of IPs, but you can try it - download eMule, install it, disable ed2k network protocol, enable Kad and see if it works without servers at all.

    Double standards here are horrible. It seems normal and accepted to use a photoshopped photograph of a respected businessman and technological innovator turned into a killer cyborg for a Slashdot section (the Gates borg logo), but drawing a nice funny image based on somewhat wordplay when it concerns an open-source browser is taboo.

    It's entirely possible to provide respectful criticism, as bersl2, chipster and phoxix did. It's also possible to just laugh, appreciate the (amateurish, but nice) artwork and go on. Even when you are not into furries.

    That doesn't change the fact that BitTorrent is a shitty network for filesharing, as opposed to network to "aid standard http downloads".

    True, but if you open a public web interface for searching for ed2k links, you may get exposed to legal problems (e.g. ShareReactor and ShareConnector).

    Correct, but there are still many more ways to distribute the links than .torrents. The system is still not perfect, though.

    Then there's the problem of peer discovery. How do you find the Kad network if the lawyers take down the public lists of popular ed2k servers?
    Via other nodes. Until the lawyers take down half a significant chunk of network at the same time, you will be able to connect to someone who is online, get your leg in the door, so to speak. After that you instantly learn about more nodes. Kademlia was designed specifically with redundancy and resiliency in mind, so (even though I don't have the math handy) I believe it can withstand the lawyers.

  6. Single point of failure on Examining Bittorrent · · Score: 4, Insightful

    The study shows how vulnerable BitTorrent is to failures of Suprnova mirrors and trackers. Kill a large .torrent host and you effectively kill the network. Kill a large tracker and you severely cripple it. In comparision, ed2k network is much more resilient to attacks.

    First, you don't need servers to distribute ed2k links. A short ASCII string effectively replaces a large .torrent file that needs to be hosted on a large server. You can send an ed2k link by e-mail, IM or post it on Slashdot. Furthermore, ed2k has excellent search capabilities - both via servers (very fast and very efficient) and via distributed Kad[emlia] system (fast and efficient). With the ability to check the filenames and comments for a certain file, you are relatively safe against fakes even when you can't use verified links. Of course, here I deliberately ignore the fact that both networks need "community portals" to inform users about released files, to provide forums for discussion, etc.

    Second, the servers play only a secondary role, even if many servers would go down, that would have a small impact on the network because of source exchange. And using Kad it's even possible to operate entirely without servers.

    I do not hate BitTorrent, really. Even though I am a long time eMule user and even though I am very annoyed by the apparent popularity of BitTorrent here on /. and elsewhere (as if other networks don't exist), I still don't hate BT. Actually, I tried it again recently and was very satisfied with the download speeds. I don't wish BitTorrent bad. But with the recent developments with police raids on torrent sites and ed2k link sites in Europe the networks will be tested and I am not sure BitTorrent is best prepared for it. Suprnova appears to be safe because of its geographic location, but it still remains a single point of possible failure. I don't think ShareReactor was as critical to the edonkey2000 network.

    I was probably not very precise in expressing my point (being a non-native English speaker, or just not paying enough attention to communicating clearly). I meant that most of the language learning, even when done in some of the biggest name language schools, would seem to a computer as repetitive enough that it can handle it.

    For example, the testing, various exercises, basically everything that is being done with the exercise books can be done with computers, often better. And, more importantly, the computers can replace a teacher for monitoring, motivating and providing feedback in such simple (to a computer) learning tasks.

    Most desktop applications can use parallel processing just fine. Word processors, music players, image editors, etc. all can break the job into small independent chunks. But as much as I would appreciate faster processors, I'd enjoy faster storage devices even more. Even though my CPU is at most 10-15% active and only 40-50% of RAM is used, when enough applications want to access the disk simultaneously, the computer can slow to a crawl.

Then you go to your study and the sun still shines in your window. You go to another room to exercise and the sun still shines. You get the point. That alone can be worth the extra price - ask any real estate dealer about the price difference between apartments with windows mostly to the south vs. to the north side of the building (in the Northern hemisphere).

    Also, I don't think that this feature is that expensive. 1000$ / square meter is not that high. New apartments in Helsinki, Finland cost 1200-1400 euros (1500-1800 dollars). Apartments in Moscow, Russia cost 2000-3000 dollars. The same in UK and US is probably about 3000-4000. And that is without remotely controlled AC or cool extra features like rotating floors.

    Drilling and repetitive tasks constitute most of the language learning. Not that I don't imply boredom and sheer memorization. No matter how interesting, engaging and creative the lessons (and homework) are, a good deal of them consists of simple repetitive tasks. I'd venture to say about half of them does. And while you would need a human mentor for the rest of the experience, a computer can be extremely effective at what it does. Furthermore, don't forget that many tasks which are currently best performed by a teacher can probably already be computerized quite well, often in the context of game/online experiences.

    Good comment, but I think your experience betrays you somewhat. Learning a foreign language is not necessarily about learning to speak it. I I had to measure how much time I spend reading in, writing in, listening to and speaking in English, the proportion would probably be something like 50/25/15/10. Obviously, reading comprehension is much more important, and that's where computers are much more effective than in drilling the student to speak. That would mean that computers are already capable of teaching a good share of the curriculum.

    BTW (not bragging, just questioning the observations you're talking about with another anecdote), my personal story is that I managed to learn English very well without going to England. I can't put an arbitrary date on which I became proficient in spoken English, but when I graduated from the institute (ending my English lessons) I already had great pronunciation and was routinely asked where did I learn such a great English (after people overcame the initial shock that I was not British). I am not saying this applies to everyone, but perhaps most people just don't get good enough education that they need to visit England?

    That site was remarkably effective. It was engaging, the learning was fun, and there was some very basic stimulation of the student. A well-programmer computer can easily replace a teacher. Especially, when teaching something as simple as language. Sure, a human teacher is still needed, but a computer can handle a lot of repetition, and repetition is the mother of learning.

    I learned a lot of English using computers too, this time for real. Playing Civilization helped my vocabulary immensely. But ask an average non-native English speaker what a "granary" is and you're likely to get a blank stare in return. :)
