“The future is already here. …” *
I have been working on a little project that involves data mining some personal history. One of the things I have been trying is using principal component analysis to reduce the dimensionality of my data to something I can get an intuitive feel for, so that I can try to ficure out what are [...]
We had a nice half-bottle of Acacia 2001 pinot noir, Napa, Carneros
I had a nice salad, a tasty rare Ahi tuna, with an Illy espresso to finish. P was not so lucky, with a salad that she found overdressed, and a fish dish that both she and I found overdressed.
Rudy Rucker and his class have done a good job of providing
applet versions of some of the cellular automota from Stephen Wolfram’s amazing book book “A New Kind of Science”.
I read the book when it first came out. It is nice to be reminded again at how amazing it all is.
Some interesting technical events sponsored by the SDForum.
I am giving my self a crash course on some data mining techniques for a project I am working on. Here are some things I found useful.
In Matteo Matteucci’s site at Politechnico di Milano is a nice little introductory tutorial on clustering algorthms, complete with interactive demos. A similar page is Tariq Rashid’s University [...]
Just back from an amazing whale-watching boat trip on the straits between San Juan Island, Washington State and Vancouver Island, British Columbia. We were lucky in that all of the local pods of Orca had come together to socialize and hunt for the salmon sheltering from the strong ebb tide currents in coves along the [...]
Interesting. I thingk I might be able to use this in my “personal data mining” experiments.
A C/C++ programmer, used to using sizeof, might be suprised how hard it is to figure out the memory footprint of Java object. Of course relying on memory sizes is very bad for portability, but sometimes when tuning applications you do need this information.
This article walks through some measurments that reveal:
Object [...]
Just testing to see if I can post to this blog from my phone.
Finally we are starting to be able to see some detail of Titan’s surface through the haze of its atmosphere.
