  1. Perhaps... on DoJ - Making Data Public Would 'Crash System' · · Score: 3, Insightful
    If the computer will crash by accessing these records, then this implies the records are inaccessible. Not to mention that if the records magically 'disappear' all they have to say it "look we told you so"

    Perhaps it's not as simple as that. From what the DOJ seems to be saying, extracting and compiling a report of this size using the existing interface could, quite understandably, render the system unstable. In theory, then, such a system may behave unpredictably and could potentially damage the database. That would, of course, imply that the DOJ database is built on unstable, outdated technology--but we already knew that. They're working to improve that, but it will take many years and millions of dollars.

    The reporters aren't asking for (nor are they entitled to) a complete backup of the database. That would be comparatively easy to provide, but is obviously out of the question, as it would include much more than just the authorized content.

    Perhaps they'd have better luck if they made a whole bunch of small queries: Instead of saying "send me everything you've got", they could say "Send me all relevant content for August 1947", then "Send me all relevant content for September 1947", and so on.

    You could argue that the instead of forcing the reporters to take the time and money to make thousands of small, separate requests, they should be able to make a single blanket request and have the government office subdivide it internally. However, such an assumption would not take into consideration the fact that you're working with a government office that is only helping you because they're required to by law. Give them a single excuse to say no and they won't hesitate to give you nothing at all.

    I'm sorry, my friend, but thirteen servers does not mean decentralized it means replicated. The fact that they are geographically dispersed doesn't matter.

    I'm sorry, my friend, but it most certainly does mean decentralized. Here's why:

    Decentralized means "having power or function dispersed from a central to local authorities". Each individual top-level nameserver operates entirely independantly of the others to the extent that it is capable of remaining completely operational in the absence of the others.

    DNS is actually the epitome of a decentralized service--as perfect an example as there comes. Assuming it is implemented as perscribed in the RFCs, there is no single point of failure (an incorrectly implemented DNS system is not the result of a poor design, it's the result of poor implementation--you can't blame DNS).

    There are 13 totally and completely independant top level servers. The only thing that ties them together (in a practical sense) is that they speak the same protocol and synchronize with eachother if possible. All top-level domains have at least two nameservers (generally much more), and all second level domains are required to have at least two authoratative nameservers as well. If any one of these servers in the whole chain fails at any time, the others will pick up the slack--it's part of the protocol.

    Implementing this service correctly such that no failure will take down your own domain is left as an exercise for you. It's your domain and your nameserver. You're responsible for insuring that it works. The "system" correctly assures that each one of your own nameservers will be queried until one responds. If you take all of your own nameservers offline, there's obviously nothing that the DNS system can do to help you. That's what Akamai's problem was. Don't blame DNS.

    I don't think that's the kind of intelligence they were talking about. There's a sort of "collective intelligence" you see in communities of "unintelligent" creatures, like ants or bees. Each does a fairly simple task which may or may not help out, but together they get something accomplished. The community seems intelligent, but the individual doesn't.

A community of drifting robots will likely find some free-floating parts to the space station, but probably won't find all of them--just like a community of ants isn't going to find ALL of the food within a given area, especially when that food is constantly drifting away in a boundless universe.

    If you want to develop a new tool and have have the bazaar dev model work like ESR told us all it should, then Fedora is a great place. I remember when Fedora was first getting started, I offered to start development on a much needed tool, and I got no less that 7 different offers for help from other non-RH participants in just a week. The prospect of having your tool built under the oversight of RedHat, and almost guarantee that it will be included in the distro is enough already to get all the outside support you need. Fedora was a brilliant idea. It was executed horribly, however.

    Offical support and direction was difficult to come by. "Read the docs," they said, but there was precious little written about how we were to proceed. Common questions were: how should we communicate, where should we host the project, how do we best get our product to integrated into the RH environment. All the "offical" Fedora components were hosted on RedHat's own CVS server and had entries in RedHat's official Bugzilla site. What about our project? We're writing for Fedora, for RedHat. We were even given the go-ahead by RH staff. Now when do we get CVS and Bugzilla? We want to start building here.

    RedHat staff has been "very busy" trying to answer our questions and satisfy our reasonable requests. Apparently there's red tape everywhere--legal and logistical issues enough to make a man cry. Stuff can be fixed, but it takes time.

    We sit and twiddle our thumbs hoping for some answers. Status updates are few and generally cryptic. RedHat is still "very, very busy" and is apparently making progress.

    In the mean time, other commitments have commanded my time and I've had to abandon my post as a Fedora developer--at least for now. Now I look back and wonder how much I actually got to contribute.

    It was a wonderful environment. Your work was almost guaranteed to be included in the distro (assuming you were filling a posted need). And I, a nameless nobody in the Linux world, had on multiple occasions asked questions and gotten prompt, insightful answers from both Eric Raymond and Alan Cox. I really felt like I was doing something important.

    But the delays and disorganization, good heavens. What frustration is was to try to get any offical assistance or direction from RedHat. Their developer support infrastructure was nonexistant at best. To borrow an old metaphor, they were building a passenger jet in the air with Fedora, and we the passengers expected to be joining something a little more ..erm.. functional than we experinced.

    Fedora's not a bad idea. It's a great idea. I was (and still am) fairly excided about the whole prospect. But it would have been nice if RedHat had prepared itself and built some sort of support system before bringing the rest of us on board.

    Patenting a method doesn't make it popular, it makes the method expensive (or even illegal). This means that now whenever the RIAA tries to destory p2p network with fake content (which they currently do), they'll have to pay this kid royalties--how ever much the kid wants--or they're not allowed to do it.

    This opens up all sorts of new doors for us. Doesn't anybody see the implications here? We can actually use the patent system we've argued against so vehemently to our advantage. The ability to patent is the ability to write law. You can use patents to make almost any unwanted behavior illegal.

    Take a page out of Microsoft's book--don't try to patent overly general techniques--pick very specific things you don't other people to do, and patent it:

    • Patent #3234732223134: "A method for preventing software piracy of office suite and operating system components by configuring the client to periodically report back to the authoring company"
    • Patent #3234732223135: "A method for preventing the unauthorized duplication of copyrighted material by only allowing such material to be played using pre-certified devices"

    You can then use your shiny new patents to either (A) fund your organization's fight against patents, or (B) simply make the patented behavior illegal.

    The key that we've learned from past patent suits is that if you make your patent specific enough to your targeted application, you won't have to worry about prior art. ("Sure, they may have done something like this before, but they didn't do it with web browsers"). You really can patent just about anything, we've seen more than enough absurd patents to know that. You just have to beat the bad guys to it: patent it before they get a chance to put their plans into effect.

    And the end result? Perhaps the business disruption created by these crazy patents will spur a reformation of the patent system, or perhaps angry consumers will continue to be able to write their own laws to fight unwanted business practices. Who cares? Either way we win, as long as we're the ones getting the patents.

    Now, go to, and make it happen!
