More Mapping of the Net 109

    i tried to grab at least the images linked to directly on the front page, in the hope that i could mirror them, or at least pass them on to someone else to mirror them. this was when the article had only 4 responses (all -1, of course).

    the site was already toast. i got half of one image.

    wouldn't it be cool if slashdot could choose 5 or 10 trusted people (slashdot users who had previously performed a good public service and mirrored old articles) to get the story 5-8 minutes early?

    • Better yet, why not make a P2P client and have one perosn download the files first, then set it up so everyone can just download from everyone else...

      I'm sure this has been thought of and discussed before, and I'm pretty sure someone even has a real client for distributing web pages P2P, so I claim no responsability for the plan, but i still think it'd be better than having mirror after mirror taken down.

    • Another idea would be *much* easier to code, and wouldn't require anything on /.'s part. I suspect people might have already created this:

      People who have a ton of bandwidth could simply write a small Perl (or whatever language... I just happen to like Perl) script to occasionally refresh /.'s page, looking for new links, following them, and mirroring a couple links deep...

      I've thought about this a lot, actually, guess it's just that I have no life. ;) An idea like this has one major disadvantage - if everyone and their cousin has a script running to do this, Slashdot will be driven off the web by tens of thousands of these programs...

      The 'best' solution would be to have a small cache of pages on Slashdot - you could even call it "SlashCache". :) There's been a lot of discussion about the legal risks of doing this; seemingly valid arguments have been presented showing that Slashdot could find themselves in huge trouble. However, Google [] has been doing this for quite some time, and, to the best of my knowledge, has never had any legal problems.

  • I dont know whats up. But all these links are not working for me. Does anyone else have that problem?? Anyway one of the best places to get the current internet map is from Think Geek [] but thats just me.
    • Too bad the pics are already Slashdotted. Everyone will have that problem for a while. It's called the Slashdot Effect.

      The Slashdot Effect is when a server gets bogged down with requests because a link to it was posted on Slashdot. I'm not totally sure about what happens, but that's as much as I can say.

      Just helpin out some fellow /. newbies ;-)

        Now we need a new term when a major event happens and we can't get to Slashdot. Maybe the terrorist effect?
        • I actually used the term "Slashdotted" with a geek friend regarding CNN at 10:30am on the day of the bombing and there was no doubt in his mind what I meant. I really think its the best way to describe the situation. I described to my wife that the April '00 DDOS against CNN, MSNBC, EBay and others simulated with 52 machines what 10 million people had just acheived that morning.

          My former manager was from London and he used the term "fell over" for servers that died under extreme loads. I always envisioned someone scaring sheep to make them faint whenever I heard that phrase.

    The site is down, so pardon me if I'm thinking of the wrong thing. But if these are the same as the famous internet maps, they're damn cool.

    I remember when Bill Cheswick started making them. At the time, both he and my dad were at Bell Labs. He even printed two different views out for me to hang on my dorm room hall. But these have interesting research aspects in small parts. The first is mapping the internet. Damn. He has daily logs going way back, and on his website has videos of the IP's of Bosnia blinking on and off during the days of bombing them. (Google search for him). It's incredible.

    But the visualization has interesting problems. My dad did some interesting work on the computational geometry structure that allowed for these things to be visualized. They have various springiness between all the connections that eventually reach the state that's displayed. The colors can be assigned in various ways (the one I remember is that each different part of the IP address is a component of RGB). It's an amazing effort that's a lot less hype and a lot more science than we might think.

    For more info, the book Programming Pearls by Jon Bentley has mention of it (my copy is packed away, otherwise I would cite it), if obscure. But if you want to do cool stuff like this, it's important to remember that it's not just scripts, cs theory can help everywhere! A useful lesson to take to heart.

    From what I've seen of the map (I love previews on Think Geek) it almost looks like a fractal pattern, very organic at the very least, does anyone know if that was purposeful or just another odd facet of the Internet?

      As the writer of the layout code, I can tell you it was certainly not a design goal. The original goal was just to be able to look at the results of the traceroutes that were being collected.

      Via a variety of bugs in the layout code over the years, I've produced interesting images, such as rings, clovers, and (my favorite) hearts. However, they almost always have a fractal feel at the micro-level. This is true for almost any Eades-like layout that I've seen, so it's probably a function of the layout algorithm.

      Interestingly enough, corporate networks layout much differently that the Internet. Corporate networks tend to be very clean, while the Internet is very stringy (almost looks like the strands within some fiberglass).

      considering that the internet can be seen as a complex system (in the sense of complexity theory) it would not be surprising if maps of it did not also exhibit some fractal structure.

      for some interesting stuff on complex internet structure, see xerox parc's 'internet ecologies' area at [].

  • since thier server was just slashdotted _off_ of the very same map. Heh.

    And all you mirror hounds - back off. Some day these idiots will learn that you don't post something on the net that the /. crowd will think is cool unless you have access to via a T3.
    </troll> ;-)
    • From what I have seen not everybody KNOWS BEFOREHAND that their site is going to be posted on Slashdot's frontpage. If I didn't know about it until I was already slashdotted and on the phone with a very angry webhosting service I would personally be pissed off that I wasn't informed beforehand. But maybe that is just me being paranoid and wanting to know what the hell is going on with my own website. I am sure most site owners would be more than happy to pay the bandwidth bill that they receive due to a Slashdot posting.

    Can anybody out there convert the corrupted MPEG videos to a working format? They claim to be MPEG, but are not valid MPEG files.
    • The are not corrupt. mpeg_encode (the software from Berkeley he used to encode these doesn't output mpegs the way MSMP likes). He suggests XAnim for Linux. There are other Windows alternatives listed at davecentral [] that you might want to look into.

      • MSMP doesn't like them because they are corrupt - not in valid MPEG format. He admits this on the page, but mentions that XAnim plays them anyway (perhaps XAnim ignores the invalid header?)

    It's just the pipe out to the net is clogged, the CPU is 91% idle right now. I'm sorry it's not the world's fattest pipe, but it does handle normal traffic without problems. Bandwidth costs money, y'know? Keep trying and your requests may squeak through.

    Anyone who wants to mirror the entire page, with the embedded graphics, is welcome to, to make the material more accessible. Steve updates this page from time to time, so don't expect your mirror to stay current forever.

    It's been a great week to test my read-ahead public web caching (not without it's bugs).. it automagically grabbed the site for me luckilly, though it took a loooong time. I'm not sure if this is still needed, but try My mirror of fractalus on 12sep2001 []

    Has most of the images on it. Be warned, this poor box is already pseudo-slashdotted due to some other mirrored content at the moment, and my poor cable modem can't handle too much more pounding (I set Roxen to throttle at 40K/s outgoing).

    So, please mirror it -- but ONLY if you post the URL to the mirror here. It's still grabbing some of the images, so be patient.

    • BTW, it should be complete, save for the mpeg's.. I killed those in the interest of saving my bandwidth. I'll re-chmod em back tommorow or so, but by then you should be able to get it from the real site or another mirror.

      Yeesh.. 3 hours to get modded up.

    If someone could take the data that they used to make the still images, and made a traceroute utility that flew down each wire "quake-style" towards each network cloud, that would be cool.

    Totally useless, but cool.
    • It doesn't allow you to pick the host, and it's only a subset of the Internet (since otherwise the rendering is slow and not very pretty), but this VRML file [] does show the 'Internet as it looks to a packet.' (the moving viewpoint may not be the default one).
  • Someone earlier mentioned an animation of the maps while Bosnia was attacked. Is there any similiar traceroute data before/during/after the recent terrorism on the US?

    I by no means want to belittle the loss of human life because of this tragedy. I think it's unbelievably horrid and my thoughts and hope go out to the victims and their family and friends. I just think this would show us another dimension to the disaster.
