Hi, I have come accross a nice piece of article"The Evolving Landscape Of Social Networks: More Surprises Ahead..". It is really interesting and helpful. It...

"It starts innocently enough, perhaps the first time you recognize your own reflection. You're not yet 2 years old, brushing your teeth, standing on your...
Everything arises from atoms. Genes shape life-forms. Brain chemicals shape behavior. Assemblies of neurons shape consciousness and thoughts. Just how exactly?...
Actually it was a pretty good article. Here's my summary and comments<http://russabbott.blogspot.com/2008/05/neural-buddhists-new-york-times.html>. Basically...
Switches within DNA that govern when and where genes are turned on enable genomes to generate the great diversity of animal forms from very similar sets of...
Interesting comment. Perhaps self-consciousness is the ultimate subjective experience, it takes place in one's mind and doesn't necessarily imply anything...
If we have a computing system distributed over a large number of nodes, could it develop some form of distributed consciousness? Although the brain is a...
This may seem like a strange question but is anyone familiar with a widely accepted definition of "level of abstraction"? I haven't been able to find one. My...
Russ, Informally, in software engineering there is a widely accepted idea that by "abstracting" something you create an interface that hides implementation...
Thanks, Telmo. (I think I've seen some of your earlier postings, which I've enjoyed.) No doubt that's what it means. But I'm looking for a definition. A level...
Russ, It sure is hard to define. I would say that the idea of "level of abstraction" is strongly related to language and meaning. As they say in the Matrix:...
Sorry for the late response, I was on vacation. I think Telmo is right, by "abstracting" something you create an interface that hide the details of an...
Grady Booch about "Software Archeology": "The moment you write a line of code, it becomes legacy. If the cumulative mass of that legacy is small, then there is...

Slides which describe the LinkedIn Architecture originally (2003-2005), advanced (2006) and today (2007-2008). It is interesting to see the evolution of the...
Hi, Interesting indeed, Jochen, thanks. Also interesting how C++ is still the right tool for computationally demanding problems: # The cache is implemented in...
According to Sandra Mitchell and her book "Biological Complexity and Integrative Pluralism", (Cambridge University Press, 2003), a complex system can be...
A strange attractor is an attractor with chaotic dynamics or non-integer dimensions, examples are the well-known Hénon, Rössler, and Lorenz attractors. An...
Are the following phenomena good examples for emergent properties? - a "who eats whom" foodweb is an emergent property of a complex ecosystem. It emerges as a ...
Hi Jochen, I agree with the first two but am not so sure about the strange attractor. Isn't the strange attractor just a description of the system's behavior,...
Hi Jochen, Telmo, I think of emergence as something that persists, where the persistence is a result either of the existence of an energy well (static...
Hi Jochen, et al, I've been lurking here for a couple of months. Interesting forum, thanks for hosting it and making it generally available. Some thoughts ...
Here is another example of emergence: PageRank "a Web page, when taken by itself, is hard to evaluate regarding its usefulness, correctness, and popularity....
I think the interesting cases of emergence happen if two worlds are in coincidence with each other, or if two universes meet each other: if there is an item...
