  1. Nagle on Fast TCP To Increase Speed Of File Transfers? · · Score: 4, Informative

    It sounds like they are working on a replacement for the Nagle algorithm. Nagle works well on clean connections, even if badly tuned slow-start gets annoying when you have gigabit connection and it still takes a minute to ramp up to full speed on an ISO download. Where "fast tcp" would really help is on a dirty connection. I had to connect to a supercomputer a few years ago over a 100Mbps link that corrupted or lost 30% of all packets and I had to use my own streaming on top of UDP to avoid getting hammered by shrinking windows (I still needed congestion control.) On this type of connection I'd expect their "fast tcp" might give a 10x speedup. On a normal non-noisy and relatively slow DSL connection, like I have at home, I'd be surprised by a 10% speedup.

    In other words the story is all wrong, but what they are doing is actually worthwhile. You sometimes have noisy networks, especially when they are wireless or in an industrial environment. The big long haul telecoms lines are better off doing error correction on line, but in the last mile you never really know the noise characteristics so this should be handled better on the TCP level. I would probably do something like FEC with the number of recoverable errors per packet and per lost packet per logical block, tuned to the error characteristics of the network. Then call it TCP2 and release an RFC and some BSD licensed source code.. (I thought of doing this as part of building an ISP friendly P2P protocol but decided I didn't have the time..) Their solution has the advantage that it works just great with regular old TCP implementations.

    As it currently stands, most musicians have the option of buying out their own recording masters after 30 years built into their contract, right?

    hehehe

    Actually, book authors usually get their copyrights after the book has been out of print for a certain time. But this is changing since publishers can keep a book in print forever by just using print on demand. In the old days you had to make large print runs so the book was out of print as soon as you sold the last copy and didn't print another run. Musicians have been screewed from day one, while there used to be hundreds of book printers, there have always been just a handful of recording labels. Also, musicians as on average have been younger and more foolish than the average book author.

    wow, that's definately a handfull of interesting information and certainly furthers my impression that the current IP/copyright laws have gone to the waste and really makes a moral case for p2p file trading, black market dvd's, etc etc.
    I had the same thought after I wrote it, I knew it all before but when I look at the whole puzzle together it's not exactly pretty.

    one point you made was regarding an individual's human right to privacy. while i do think that the US constitution indirectly grants a right to privacy, i think that right is very limited. i think that right is nearly absolute on your own property, and diminishes greatly as you yourself enter a public domain.

    I think of privacy as a right, but one you often trade away explicitly or implicitly for some other benefit. You implicitly trade some of it away for power or to further your view of the public interest when you enter politics. You explicitly trade it away when you buy land; and, implicitly when you engage in practically any commercial transaction. It's because we implicitly trade away some of our privacy hundreds of times a day that privacy is such a hard thing to get one's head around. The courts in the USA have dealt with this by applying a reasonableness test. The EPA can't make a surpise visit to your fenced in private forest without some good reason to think you are doing something horrible, but they can make an appointment with you to make an inspection and hold you to it. Any reasonableness test is problematic because it's a subjective test like the community standards test for illegal smut. You basically get as much privacy as the community thinks you should. This wouldn't be so bad if you just got less privacy when at a midwestern commune than in an ethnic Japanese community, but it's the police and the broader community that define your right to privacy, so it's ripe for abuse by racist and otherwise bigoted definitions. (Their definition of your right to privacy, not our right to privacy.)

    Rights have to be balanced when they conflict, "Life, liberty and the pursuit of happyness" but you can't kill other people for body parts to continue living, nor can you enslave others to buy your liberty. There is some thought that by pursuit of happyness the founders actually meant the pursuit of power to influence the development of the society, i.e. political power. I don't know if I buy that, but even if that's what they meant you still can't assume that power by killing all your rivals. You can hurt other people in the excercise of your freedoms but there is has to be reasonable, you can destroy someone's livelyhood for your political ambitions, but only by convincing others not to deal with him while respecting his right to privacy, to life, etc. Another simpler example might be fraud, you can say what you like, you can lie to your hearts content, but you can't lie to get someone else's money, there is an expectation of a certain level of honest dealings. Even the much maligned car salesman is expected to tell the truth if not the whole truth. If you ask if the car has been in a major accident they will tell you No, not that I know of but are not expected to tell you they didn't check or say, Hey did you notice the frame is bent, the tires are all bald, and that clutch feels like it will break before the end of the year...

    the only thing that i can think of to compare to is paparizzi photos of celebrities. if i snap a shot of a celeb, or grab them on tape, or on video/audio, whatever, i own the copyright to that material.

    Yes, but you can only use it in certain ways, you can use it for art, for a news publication, for a tell all book about them or for a book on your life taking pictures of celebrities. But you can't use it on a promotional poster or in a movie or entertainment program on television. If you take a picture of me (definately a non-celebrity) the use is even more restricted, basically to an art installation or news if I'm an actor or a bystander wherever the news is unfolding. You might get away with using it in an art book, but you might be hit hard if I win a lawsuit since you had the opportunity to contact me and get my permission. The law for using my image is different than the one for celebrities. For me the judge balances my right to privacy against your first amendment rights, for a celebrity/politician they have lost much of their privacy rights so unless you do something truely rotten to get the picture the judge balances their commercial rights and moral rights to their image against your first amendment rights. So the celebrity sorta trades away their privacy for some extra rights. They aren't human rights like speech, thought and privacy, etc. Hence they are usually weak when compared to your political/expressive/reportage speech rights, but often beat your commercial speech rights. I have a friend working at one of the big media companies (hint, they were in violation of the FCC 35% rule before today) that gets permission for everything that goes on their technology news program because it is considered entertainment programming. Scary, huh?

    Actually, in any of the 150+ WTO countries it's always copyrighted unless you explicitly donate it into the public domain. You may forfeit some rights if you post it on USENET, but not if I post it for you (unless I did so with your consent, or it was a trade secret that you were careless with.) And the "if I create it, it's mine" will just get you in heaps of trouble if your political bribes are still in the low billions. You can bribe a circuit judge, but good luck with the Supreme Court, you've got to hire theirs sons and buy a president for that kind of influence. (PS Anybody notice how cheap those Brooklyn judges were? A few hundred $$$ saves you a million on your divorce settlement, I guess it isn't just paranoia that prevents me from voting for judges when they are all on both the Republican and Democrat tickets.)

    what if i record from 1/2 a mile away and get a crappy sound, but still get some noise from the show. who ownz that recording? you do the right to copy it? those rights belong to you, the performer[s] and the songwriter[s] acting in together or under compulsory licensing regimes. the right to distribute it? same as copying, it is presumed that copying is for distribution unless it is a small number of copies for backup, or a transfer to another media, in which case any of you and others may be able to do it under fair use rights. (being a library helps if you're in the others category) what if i fly overhead and record video of the concert, who ownz my video recording? this is completely immaterial to copyright, see first three answers how about my video recording of shot over some farm land in iowa? also immaterial to copyright, if there is a creative work in the picture created in the last 25 years, it is copyrighted, you can only use the video under fair right rules (i.e. it is incidental to your art, or your reporting news, etc.).

When you discover that something you did with the best of intentions actually made things worse you will feel bad, but you won't make the same mistake and you'll try figure out how to tell others you see making the same mistake about it. Before long you'll feel good again. Is it some kind of revelation that being a good person makes you feel good?
