Tekzilla Daily Tip #562: Windows: Monitor Network Activity
Bring back XP's blinking networking iconDo you miss XP and Vista's blinking network icon? On today's Tekzilla Daily, Veronica shows you how to bring it back to Windows 7 with the help of the free tool called Network Activity Indicator.
Tekzilla Daily Tip #494: Discover Where Google Users Live
Map your fellow GooglersCurious about where all those Google users live that are searching for, for example, "Revision3"? Veronica reveals a sweet Google site that uncovers all those details.
Propping Open the Document Trapdoor
Computer document processing often starts with an abstract, structural, representation before entering a processing pipeline which creates a desired layout and appearance. But unfortunately the whole system resembles a series of steps in a one-way chemical reaction, or the successive irreversible stages of creating assembler code using a compiler. This `one-way function' behaviour is most obvio...
Mainstreaming Psychedelics: From FDA to Harvard to Burning Man
We're now in the midst of a worldwide renaissance in psychedelic research, after decades of political suppression. Scientists from around the world will present their new findings at the largest psychedelic conference to take place in the US in 17 years, on April 15-18, 2010, in San Jose, CA (http://www.maps.org/conference/ ). Even media reports, which usually mention in passing the widespread ...
Learning Low Dimensional Manifolds
Many read-world datasets can be characterized as follows: the "extrinsic dimension" of the data is high, but the "intrinsicdimension" is low. Consider for example the data generated by a motion capture device. Such a device typically tracks a few hundred dots located on a special suit worn by the tracked person. Each time point corresponds to a vector consisting of the (x,y,z) location of each ...
Practical Life Extension Results
Genescient is the world's first computational biology company founded on the use of artificial biological selection to cure the diseases of aging. Our laboratory animals have been selected for longevity through 750 generations for the equivalent of 15,000 human years. I will describe Genescient's multiple pathways toward accelerating human longevity, with parallel enhancements of vigor and func...
Avi Bryant on Trendly, Ruby, Smalltalk and Javascript
Summary Avi Bryant talks about the iterative process that led to Trendly (http://trendly.com/ ), using Javascript, Ruby and Java in the process. He goes on to give his view on the state of Smalltalk and Squeak and talks about his experiments with writing a Smalltalk that compiles to idiomatic Javascript to make use of all the modern Javascript VMs. Bio Avi Bryant is the co-CEO of Dabble DB, a V...
Fun with Light (Quantum Computing: A Physicist's Perspective on Recent Developments)
The lightsaber is a supercool gadget that all of us would like to get one. It exhibits many novel light phenomena, notably the light blades of two lightsabers could interact with each other. Unfortunately it takes an enormous amount of energy to achieve that. One of the main difficulties of making a lightsaber is that photons normally do not interact with each other.In the first part of the tal...
The Marriage of Fractals and Splines: Fractals with Control Points, Splines as Attractors
Fractals and splines have very different geometric features. Fractals can be continuous everywhere, yet differentiable nowhere. Fractals are often selfsimilar curves with fractional dimension. And fractals are also attractors, fixed points of iterated function systems. In contrast, splines are piecewise polynomial curves, so well behaved that they are often used for large scale industrial desig...
