Gnutella is a pure P2P network, without any centralized servers. Using the same search protocol, such as Gnutella, forms a compatible network for different applications. Anybody who implements the Gnutella protocol is able to search and locate files on that network. Here's how it works.

"In P2P search (a.k.a. distributed search), each individual connected to the network serves its local index as a source of search. Instead of having a central company and a central server, each participant of the network is a search repository. Since we are talking about web indexing and web searching, a user's internet cache might be their contrib...
"A P2P application is different from the traditional client/server model because it acts both as a client and a server. That is to say, while they are able to request information from other servers, they also have the ability to respond to requests for information from other clients, at the same time. Figure 1 shows the architecture of a P2P networ...
"A typical peer-to-peer application has the following key features: • Peer discovery. The application must be able to find other applications that are willing to share information. Historically, the application finds these peers by registering to a central server that maintains a list of all applications currently willing to share, and giving that ...

Peers share their local indexes (or specific fragments of local indexes) by posting meta-information into the P2P network. This meta-information contains compact statistics and quality-of-service information, and effectively forms a global directory. However, this directory is implemented in a comple...

As a result, using a P2P network means that your online activities become public knowledge. OneSwarm is a new peer-to-peer tool that provides users with explicit control over their privacy by letting them determine how data is shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, it can be shared with ...

2011年9月19日 · Boaventura de Sousa Santos: "The sociology of absences consists of an inquiry that aims to explain that what does not exist is, in fact, actively produced as non-existent, that is, as a non-credible alternative to what exists. The objective of the sociology of absences is to transform impossible into possible objects, absent into present objects.
Learning II is learning to learn. Learning III - Hyper-complexity: Learning III is a change in the process of Learning II, e.g. a corrective change in the system of sets of alternatives from which a choice is made. It works much as Learning II but on a higher level of abstraction. Bateson points out that this level of learning is never achieved ...
Technical Description. "DHTs obviated the server from P2P networks. A DHT is a hash table that partitions the keyspace and distributes the parts across a set of nodes. For any new content added to the network, a hash (k) is calculated and a message is sent to any node participating in the DHT. This message is forwarded from node to node until ...
