Dare Obasanjo aka Carnage4Life - ASP.NET Caching vs. memcached: Seeking Efficient Data Partitioning, Lookup, and Retrieval

by brianwaustin (via)
I recently discovered memcached which is a distributed, object caching system originally developed by Brad Fitzpatrick of LiveJournal fame. You can think of memcached as a giant hash table that can run on multiple servers which automatically handles maintaining the balance of objects hashed to each server and transparently fetches/removes objects from over the network if they aren't on the same machine that is accessing an object in the hash table. Although this sounds fairly simple, there is a lot of grunt work in building a distributed object cache which handles data partitioning across multiple servers and hides the distributed nature of the application from the developer. memcached is a well integrated into the typical LAMP stack and is used by a surprising number of high traffic websites including Slashdot, Facebook, Digg, Flickr and Wikipedia. Below is what C# code that utilizes memcached would look like sans exception handling code

Global Consciousness Project Dot - Correlated Structures in Random Data

by ycc2106
Webpage add-on button that changes color The Global Consciousness Project collects random numbers from around the world. These numbers are available on the GCP website. This website downloads those numbers once a minute and performs sophisticated analysis on these random numbers to see how coherent they are. That is, how probable it is that the numbers are generated as they are. The theory is that the Global Consciousness of all the people of the world affect these random numbers... Maybe they aren't quite as random as we thought.

Using the Semantic Web for Genealogy

by xibe

(...) genealogy seems to be an obvious application of an RDF ontology and the Semantic web. I've investigated making use of RDF and the Semantic Web for Family History. The results of my investigation are here on this web page. In my work, I created a program to translate files in GEDCOM format to XML. I also wrote several stylesheets which translated the data into a new format GEDCOM XML, HTML, and RDF.
