This is really sad

I was looking at the Maxima manual, and I had a "I wonder what this does" moment. It had to deal with Hilbert Maps, which may be found on Sourceforge at: http://maxima.sourceforge.net/docs/manual/en/maxima_54.html#SEC268. After I put in the two commands: (%i1) load(fractals)$ (%i2) plot2d([discrete,hilbertmap(6)])$ into xMaxima I obtained this: I was still not satisfied, so I did a quick Google search for Hilbert Maps. I clicked on one of the resulting images, and wound up here: http://www.team-cymru.org/Monitoring/Malevolence/maps.html. This was all nice and good, but I wanted to know what Wikipedia said as well (http://en.wikipedia.org/wiki/Hilbert_curve).This also led me to R-trees (http://en.wikipedia.org/wiki/R-tree) which remind me of network visualization, and Gray Codes which make me think of Minecraft. I performed a Google search for Hilbert Maps + Minecraft, and then a search for Minecraft + Gray Codes. This Youtube video by Neumann Gregor was an interesting result (http://www.youtube.com/watch?v=Y4ebK-qvAlk). Team Cymru also led me to xkcd, where I found a wonderful circuit diagram: as well as a map of the IP4 space of the Internet: Team Cymru was great because they also linked to The Measurement Factory at http://www.measurement-factory.com/. While there, I was interested in what CAIDA was. From the link (http://www.caida.org/home/), it turns out they are all about Internet Data Analysis.

VRML/X3D

Awesome! There is another way to describe 3D information for the web. In its most recent version it is called X3D. http://www.web3d.org/realtime-3d/ In addition, OpenVRML has libraries that add VRML/X3D support to an application. http://openvrml.org/index

The Aseptic Room

The room was aseptic. There was no laughter and it was squeaky clean.
