How does Facebook make money?

Facebook is the most well-known social network online. It allows you to speak with all your friends in live and also to keep in touch with them whenever and wherever you want.
But how facebook makes money?
Facebook use a really simple method: put advertising on the website.
There are many companies which want to appear on the Facebook websites because there are millions users in the world and that is a really good strategy to be seen by many people at the same time.
Advertising is the only method used by Facebook to make money; they don't have any subscription fees and they don't really sell any information because all is free on Facebook.

Hewlett-Packard build intelligent memory: the memristor

The researchers who work for Hewlett-Packard have developed a working unit of a memory circuit that exists already in theory for 37 years. This new technology could ultimately replace RAM and make computers more intelligent by tracking data it has retained. This technology, called memristor, could allow computers to make decisions by understanding past patterns of data it has collected. In other words, memristor would have properties similar to a synapse in a brain.
A memristor circuit requires lower voltage and less time to turn on than other competitive memories such as DRAM and flash, thus it uses much less power. Memristor circuits can also store more data than flash memory. Memristor is the fourth fundamental circuit element (the other three are resistor, capacitor and inductor) and has properties that cannot be reproduced by any combination of the other three elements.
HP is not going to reproduce all the functions of a brain in memristor, but the company tries to build a simple computing machine that operates on a different principle from today's computers. The scientists have created the memory by applying a charge on a circuit with blocks of titanium dioxide. The actual resistance of the memristor changes depends on the amount of current flowing through the circuit. When the current is turned off, the memory retains the information it has acquired.
Although the concept of memristor has been real for some years, the memory prototype is an academic device that will first work its way to academia, but it really could hit the commercial semiconductor market in five years.

New Google for Web 3.0 created by TenForce

Convert information into data which can be read by computers and make such data usable for businesses and individuals is the next big challenge on the net.


The Belgian integrator “TenForce” is working on the use of information on Web 3.0. The goal is to develop a kind of 'Google' to access and view tag information. This project, for which 6.45 million € were disbursed, will last four years, and the University of Leipzig cooperate also to this project.

“The European Commission began gradually to realize the significance of tag data and make them 'machine readable', so that others could access them more easily," adds mister Deblieck, the co-founder of “TenForce”. The purpose is in reality to develop a machine which will index, solicit and combine data. Currently, there is still no software available which include these kinds of use.

In addition to developing a “machine index”, it will also remove remaining barriers between data providers and users, and solutions must be found in terms of reliability. This technology will ensure that end users can be sure that information always comes from and to the right source.

Some parties want to be compensated for the use of data they make available; these data should be traceable, so that you can be paid each time your information emerges somewhere.
