The network, the internet and the Web

31 May

Were years of the Cold War, the ongoing tension between the communist world led by the Soviet Union and the capitalist world led by the U.S., and the first idea of the electronic network was not having a central command so that he could keep the links in the event of destruction of some points by a war between the two blocks in tension.

So the network should be mounted without a central command, a system in which all points (network nodes) had autonomy and where the data transmitted in any direction or order not to lose the contents, the project was outlined ARPAnet Paul Baran, designed by Agency Advanced Research Projects (Advanced Research Projects Agency) of the U.S. government.

But the network went out of military control in 1970 and crisscrossed four U.S. universities, but in the next 4 years the number grew to 40. The exchange of messages and files becomes possible, and universities launch several projects, among them, the Project Gutenberg Michael Hart with the publication of books, the University of Illinois in 1971.

That same year, it created the first commercial network in the U.S., Telenet, as an access service.
The name has been used only in Internet 1982. In 1983, Vinton Cerf and Khan create the network communication protocol, TCP / IP (Transmission Control Protocol / Internet Protocol), the common basis of instructions and codes used by all computers connected to the network today.

But the Web as an application protocol only arrived in 1991, with the hypertext system, prophesied by Ted Nelson years before, and now implemented by Tim Berners-Lee, came the Web, the World Wide Web

Thus the metaphor of the network becomes years later an electronic means of communication the internet, and in the 90s a mode of communication between billion person who is the Web

Social networks were only possible within this universe of hypertext with the Internet as a medium.


Communication, Noosphere y Corpus Christi

30 May

The idea that the universe has a soul or a spirit, (noon – mind or soul), bring new thinking about the meaning of our being, thinking that the current philosophy already hosts, as in Morin:

“The noosphere is not only the means driver / messenger of human knowledge. Also produces the effect of a fog screen between the cultural world, which advances surrounded by clouds, and the world of life. Thus, we find a paradox largest ever faced: what makes us communicate is at the same time, which prevents us from communicating. “(MORIN, 2001).

In etymological terms, religion is what the “reconnection”, ie, that which impels us to communicate with each other in the Christian meaning, what leads us to “Love one another” and that is exactly what we relink the Noosphere, in Teilhard Chardin who coined this word, it is precisely this communication Love (the uppercase agape) we “reconnected” to the Other and the entire cosmos, which to him, a Catholic priest, is the cosmic Christ, his whole cosmic body connecting everyone and everything.

So all Being ontic and the universe are connected to the Supreme Being who is the Being in essence, and just this Being that impels us to communicate, to express this “rewiring” the Other and the Cosmos.

Dreams and visions of Juliana of Liège of Belgium (1193-1258) expressed his Paraco and future Pope Urban IV, who created the date of Corpus Christi, maybe worth rereading for an idea of ​​world-society for which society moves current through the fog, and a cosmos increasingly known and mysterious at the same time.

Lei de Moore tem obstáculos

29 May

Moore’s Law was first established in 1965 by Gordon Moore, co-founder of Intel in 1968 and in 1975 became an executive of the company.

The original article on the law, published in electronics in 1965, was focused on economic aspects related to the cost per transistor, previous technology and scale of the new technology that was the scale of the printed circuit board (SI), which grew from small-scale integration (SSI) to medium scale (MSI), then in the 70’s came to a large scale (LSI).

But now make chips smaller and smaller, keeping pace with Moore’s Law may be more difficult today than it was last year, said William Holt, executive vice president and general manager of Technology Manufacturing Group at Intel, in a speech Jeffries Global Conference on Technology, Media and Telecom in the second week of May, and reported in PC World.

“We are closer to an end than we were five years ago? Course. But are we to the point where we can actually predict the effect, we do not think so. We are confident that we will continue to provide the basic building blocks that allow improvements in electronic devices, “said Holt.

Intel still has the manufacturing technology industry’s most advanced chip today, but it was necessary to build many new factories to new process chips, using new materials such as tungsten and Germanium (Ge) to achieve the scale of 90 to 65 nanometers, and more recently the high-k metal gates, 45 nm and 32 nm.

The technologies below 22 nm (called Silvermont) already work with 3D structures but the future must be of graphene and quantum chips, to walk in walking speed that Moore’s law.


A post turns movie

28 May


The story began at lunchtime James Erwin of Rome, Sweet Rome when he took time off to write a story imagining of soldiers, but only a few centuries before, fighting against the Roman soldiers.RomeSweetRome

Facebook: more adults fewer young

23 May

According to a survey by the Pew Research Center, made ​​with 802 young Americans between 12 and 17 years, young people are bothering with the excessive number of posts and the “drama” in the social network, which in their interpretation is due to the presence of adults.FaceEyes

The study found that a liking for Facebook, youth is precisely the posts “futile” friends on the social network, and secondly there is a concern with the need to manage your reputation online, looking at comments about her.

New blog design and Noosphere

20 May

 This posting is celebrating the launch of the new design of the blog and websiteNoosphere (the picture above  is digital art of Tatiana Plakhova).

 Just as there are the biosphere, developed over millions of years around the terrestrial sphere, according to Teilhard de Chardin, the man emerged as a single species in the biosphere on Earth, breathing in a atmosphere, but subject to a kingdom “neither more nor less than a “sphere” – the Noosphere (or sphere thinking) about coextensively imposed-on (but the more connected and homogeneous) the Biosphere “(Chardin, 1997, p. 102).

Chardin describes the development of the Noosphere in two phases one occupation Biosphere, extension or as he calls it, where “swells in the first half of the path (to the equator [he thinks the poles to the center]) … a very similar pace, proceeds historically the establishment of the Noosphere “(Chardin, 1997, p. 103), and only lately … appearing in the World is the first symptoms folding definitive and global mass thinking inside a hemispherical top … “(Chardin, 1997, p. 104) and says that the first phase had three distinct characteristics:” Settlement, Civilization, Individualization “(idem).

This movement of contraction, which he called “planetarization” in raises “a fear reflected essential element before a whole, apparently blind, whose immense layers bend over it as if to absorb much alive … as Life, after lead us by the hand into the light, it dropped back, exhausted? “(Chardin, 1997, p. 126).
“From this point of view … no room in the eyes that our fears of ‘dehumanization by planetarization’ are exaggerated, because that planetarization that both frightens us is no more (judging by its effects) that the authentic and direct continuation of the evolutionary process that historically came out type human zoo? (Chardin, 1997, p. 127).

Chardin reaffirms his certainty that the complex “economic, technical, scientific and social” … “Behaves like a body that radiates, irradiation being formed by a free energy, the nature and transformations must be the subject of a brief study” (Chardin, 1997, p. 130).
