More Mapping of the Net
An anonymous reader wrote in to say"It turns out that famous map was not the end of it, a cybergeography alert linked to this site with lots of cool pictures and animations. Turns out they didn't measure time between hosts on the poster map, and it can be used to make cool pix!"
I have two of the files mirrored on my server right now. /. for too long :)
Someone mind helping? I dont think it will handle a heavy

Here's a mirror for some of the images:

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.

This is my third try posting it, the lameness filter is causing me real trouble, is it worth it? Can't we just mod -1 lame instead of asking a PERL script to do it?
Check out this page: http://milov.nl/linkthispage.php
A Dutch doo (milov.nl) wrote a cool little linkmapping device. In his words: "Using a combination of PHP and Javascript-DOM-scripting, the structure on this page will grow in different directions depending on the number of referrers that link to it."
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).
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.
People are never as simple as their stereotypes. This applies equally to Christians, Muslims, and Emacs-lovers.
