Mientras, que pasa en el mundo real?

Primero los grafiquitos, oprimir para verlo bien

y? Ud dira?

el titulo

Comprando tierra cultivable en el exterior

La tercera ola del Outsourcing's

Los importadores ricos de comida estan adquiriendo vastos pedazos de tierra cultivable en naciones pobres. Es una inversion externa beneficiosa o neocolonialismo?

el 1ro de los grafiquitos es la cantidad de has compradas por China, 2,8 millones, y otros mas
el 2do es un mapa detallado de donde, lo raro que nosotros no figuramos.

No solo chinos, Morgan Stanley compro 40.000 has en Ucrania

el negocio, facil, si tengo la tierra, no me preocupo de cuanto vale la soja, si es mia la tierra, lo producido y lo llevo a mi pais.

Para cuando un Han Grobo?

ebooks - Kindle y Amazon

A todos nos gusta en general leer, a muchos nos gusta (o nos acostumbramos) a leer libros y literatura varia en pc, y, el paso natural, es algun tipo de lector comodo, chico.
Amazon lo fabrico (entre otros) y diseño el canal de distribucion, via una comunicacion de tipo celular, ud encuentra el libro en el catalogo, lo paga, barato, y voila, se descarga automaticamente en su lector celular, Kindle.
Pero, como el infierno esta en los detalles, Amazon NO le vende un libro a Ud, le da una licencia, eso significa que, en alguna circunstancia, ellos podran hacer uso de sus derechos como dueños, recuerde, ud tiene una licencia de uso

Y, ellos hicieron uso de sus derechos, a mucha gente, o poca, no importa el caso, le vendieron 1984 y Animal Farm para que la tuvieran en su Kindle, pero, parece que no podian ya que no tenian el derecho de hacerlo, y que hicieron cuando les advirtieron de eso, intimandolos??

Borraron de los kindle, si, ellos, remotamente, sin advertir a nadie, 1984 y Animal Farm de los Kindle de la gente que habia comprado el libro, bueno, en la letra chica decia que era una licencia de uso, asi que lo que hicieron, lo hicieron en forma legal

Ahora bien, entonces? la verdad es que no compre libros via Kindle, los alquile, por un lapso que ellos deciden a su antojo.

Aca no valen las declaraciones de nadie diciendo no lo vamos a hacer mas, solo vale decir te lo vendo, y es tuyo

De como mercantilizamos

Uno era chico, escuchaba a distintos tipos de mayores, o, al menos ponia cara de me lo banco y listo, pero, siempre hay una nueva vuelta de tuerca. Ahora bien, hay gente en esta blogosfera que mereceria estar aca, y otros, no ser requeridos nunca

This is just great. The Living Library. You borrow people not books. Yep, really. It’s an idea out of Scandinavia. Instead of borrowing a book, you can borrow a person for a 30 minute chat. An east London library has 26 “human books” available. The aim is to confront and breakdown stereotypes. You can “borrow” a Muslim; a police officer; a person suffering mental health issues; a gay guy; or a young person expelled from school.

So the stereotypes might be religious fanatic; corrupt; unstable; promiscuous; rebellious and so on. It’s about having frank and rich conversations with people and learning about different cultures or ways of living. It’s about the “borrower” offering up what misgivings or fears they might have of a stereotype and the “human book” responding.

Violence, hatred and racial issues often occur when there is misunderstanding, ignorance and cultural insensitivity. Listening to the narrative of another person who is entirely different from you is a powerful experience. The Living Library challenges preconceptions through promoting dialogue.

The Living Library was started by a Danish anti-violence campaigner, Ronni Abergel, who has taken the concept to 12 countries, including Australia where the Richmond-Tweed library seems to have embraced it with the slogan “Don’t Judge a Book by its Cover”.

I wonder how the “human books” feel. I’d be worried I’d be left on the shelf with no-one interested in speaking to me!

If you’re interested in learning more about this concept, check out the Living Library Organizer’s Guide on Amazon.

Los Precursores

Disclaimer, esto es para cuasi nerds
Despues de haber leido sobre Shannon en lo de U, le mencione a Nyquist, para aclararlo, un poco de historia de los precursores de Shannon.

Aparte de ello, la unidad, ban

y, para la linea temporal (no a la Hawking)

Quantitative ideas of information

The most direct antecedents of Shannon's work were two papers published in the 1920s by Harry Nyquist and Ralph Hartley, who were both still research leaders at Bell Labs when Shannon arrived in the early 1940s.

Nyquist's 1924 paper, Certain Factors Affecting Telegraph Speed is mostly concerned with some detailed engineering aspects of telegraph signals. But a more theoretical section discusses quantifying "intelligence" and the "line speed" at which it can be transmitted by a communication system, giving the relation

W = K log m ,

where W is the speed of transmission of intelligence, m is the number of different voltage levels to choose from at each time step, and K is a constant.

Hartley's 1928 paper, called simply Transmission of Information, went further by using the word information (in a technical sense), and making explicitly clear that information in this context was a measurable quantity, reflecting only the receiver's ability to distinguish that one sequence of symbols had been intended by the sender rather than any other -- quite regardless of any associated meaning or other psychological or semantic aspect the symbols might represent. This amount of information he quantified as

H = log S^n ,

where S was the number of possible symbols, and n the number of symbols in a transmission.

The natural unit of information was therefore the decimal digit, much later renamed the hartley in his honour as a unit or scale or measure of information. The Hartley information, H0, is still used as a quantity for the logarithm of the total number of possibilities.

A similar unit of log10 probability, the ban, and its derived unit the deciban (one tenth of a ban), were introduced by Alan Turing in 1940 as part of the statistical analysis of the breaking of the German second world war Enigma cyphers. The decibannage represented the reduction in (the logarithm of) the total number of possibilities (similar to the change in the Hartley information); and also the log-likelihood ratio (or change in the weight of evidence) that could be inferred for one hypothesis over another from a set of observations. The expected change in the weight of evidence is equivalent to what was later called the Kullback discrimination information.

But underlying this notion was still the idea of equal a-priori probabilities, rather than the information content of events of unequal probability; nor yet any underlying picture of questions regarding the communication of such varied outcomes.

A veces, vale la pena releer los libros, los que a uno le explicaban como funcionaba el mundo fisico, sin posestructuralismo, sin Deleuze, sin sarasa de variado tipo

Alguna gente que pase por aca lo apreciara, otra seguira de largo, pero la verdad, que Bill se haya tomado el laburo de poner las clases del susodicho en Internet solo causa agradecimiento, al menos, mio

disclaimer: esta en ingles, pero, independientemente de todo, se nota cuando un tipo sabe, la explica facil

40 años

el 20 se cumplen 40 años de un episodio que, nos guste o no, le demos pelota o no, marco muchas cosas, yo aun tengo por algun lado el sobre con la estampilla conmemorativa

abajo de todo, un link

One small step that altered our world view

Nasa, the US space agency, has a love-hate relationship with anniversaries such as its 50th birthday last year and now the celebrations to mark 40 years since the first Moon landing on July 20 1969.

They bring back glorious memories of the Apollo programme – the most eye-catching achievement in the history of science – but contrast with the relatively pedestrian activities that Nasa and other space agencies are carrying out today.

While the risky Shuttle mission to repair the Hubble telescope in orbit caused some excitement this year, the near-term prospect for manned spaceflight consists of little more than routine visits to the International Space Station. Sadly, the only thrills would come from a disastrous accident.

It was all so different in the 1960s. Early in the decade there was the stimulus of the “space race” between two superpowers, triggered by US shock at the Soviet Union’s 1957 launch of Sputnik, the first artificial satellite. As Lord Rees, cosmologist and president of Britain’s Royal Society, puts it: “The Apollo programme was a transient spin-off from the superpower rivalry of the cold war era.”

But the political and ideological origins of the race did not diminish its excitement. It is easy to forget now that in the early stages many experts expected the Soviets to win the race. In the autumn of 1959 they had been the first to reach the Moon (with the Luna 2 probe) and the first to photo graph its far side (Luna 3). Nasa’s first six unmanned Ranger missions to the Moon failed; Ranger 7 succeeded in July 1964.

Then the balance of space power changed, as the vast scientific and technological resources poured into the Apollo programme paid off. As Nasa got its act together in the late 1960s, Soviet attempts to develop a huge Moon rocket similar to the US Saturn launcher ended in failure.

By 1969 it was clear the US was racing against only itself. But the prospect that men really would land on the Moon – unthinkable beyond the bounds of science fiction in the 1950s – brought an extraordinary feeling of exhilaration to people round the world. As Lord Rees says: “Neil Armstrong’s ‘one small step’ gave us an image that is imprinted on the memories of all of us who are now middle-aged.”

Many space enthusiasts imagined that 40 years later we would have permanent lunar bases and manned missions to Mars. But after the six Apollo landings, the political will to fund such ambitious programmes dissipated. Since 1972 no astronaut or cosmonaut has flown beyond low terrestrial orbit, a few hundred kilometres above Earth.

Despite the lack of a sustained follow-through, it would be wrong to regard the Moon landings as a historical side-show. Apollo made a huge impact on science and technology, politics and education – and our view of the world.

The most direct impact, of course, was on the aerospace industry. Much of the technology used in today’s more limited space activities originated with Apollo and its Russian counterparts, says Simon Prince, an aeronautical engineer at City University, London. “They had to invent everything then and, in terms of materials and knowledge of the dynamics of flight, there has not been much forward movement.”

Then there are the famous technological spin-offs from Apollo to other fields of industry. Nasa lists 13 of these, including reflective insulation for buildings and water purification systems. Teflon and non-stick pans are not on the list.

Apollo also left a scientific legacy. While the Moon turned out to be grey and lifeless – to no one’s surprise – the 382kg of rocks brought back by the astronauts have helped planetary scientists to understand the history of the Moon and Earth. The samples showed both the volcanic nature of the ancient Moon and the way meteorites bombarded it after the surface had cooled.

More important was the impact on society. Barack Obama, the US president, told the National Academy of Sciences in April: “The enormous investment of that era – in science and technology, in education and research funding – produced a great outpouring of curiosity and creativity, the benefits of which have been incalculable.”

Apollo inspired many young people, particularly in the US, to study science and engineering. Indeed, some see the flowering of an entrepreneurial high-tech culture in Silicon Valley and elsewhere as a legacy of the Moon race.

However, Apollo’s widest impact of all was on the way we see our own planet. The “Earthrise” pictures – taken on Christmas eve 1968, from Apollo 8 in lunar orbit – were among the most influential photographs of the 20th century.

The astonishing contrasts between the barren lunar surface and the jewel-like blue-and-white globe shining over the horizon, almost 400,000km away, captured the beauty and vulnerability of Earth more vividly than any other image. The inspiration they gave to the burgeoning environmental movement of the 1970s was incalculable.

As Apollo 8 astronaut Bill Anders put it: “We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.”

Richard Milhous Nixon

Y, si, era obvio, pero a que viene a cuento esto, quizas, a la ruptura de los contratos, al desconocimiento de los tratados internacionales, y una pila de cosas mas
Dick fue un republicano, que puso mas controles sobre la economia que cualquiera antes de el desde el New deal, segun algun asesor suyo

pero bue, Dick recibio la onza a USD 35 y la habra dejado a 100, en fin

Aerolineas y Subsidios

Que hay que dejar quebrar Aerolineas, que hay que privatizarla, que no debe recibir subsidios, que las aerolineas en USA no reciben y quiebran com Pan Am

Sarasa total, facts

CRAF was set up in 1951, and used for the first time in 1990. At the time, the air force was paying some $700 million a year to 32 airlines so that, if a national emergency was declared, the air force could call into military service transports with a minimum of fuss and paperwork. The program has continued since then. Aircraft can also volunteer their aircraft for military service, which is easier to do right now because of the depressed state of the air transport business. During the Gulf War, airlines that had their aircraft mobilized earned $1.5 billion in use fees. The CRAF transports moved 62 percent of the troops brought in by air to the Persian Gulf, and 27 percent of the air freight.

Y un dia cruzaron el Atlantico

Estuvieron en Asia, luego en Africa, y siguiendo la ruta del Almirante Eunuco desde Africa, cruzaron el Atlantico

Chinese talk to Repsol about Argentine arm

Two of China’s biggest oil groups have approached Repsol YPF, the Spanish oil company, over possible asset purchases and joint ventures worth billions of dollars, according to people familiar with the matter.

The Chinese proposals could lead to the largest outward investment deals undertaken by Chinese companies, which are eager to gain access to natural resources to fuel the country’s economic growth.

Repsol is discussing a possible sale of its 75 per cent stake in YPF, the Argentine company that accounts for two-thirds of the Spanish group’s oil production, to CNPC, parent of listed PetroChina, in a deal that could value YPF at $17bn (£10.4bn).

CNOOC, meanwhile, has discussed with Repsol a proposal that could lead the Chinese group to invest at least $15bn in a joint venture that would house some of Repsol’s main exploration and production assets outside Argentina. CNOOC is also interested in a minority stake in YPF .

“The Chinese groups have been talking to Repsol for months about acquiring assets,” said one person with knowledge of the negotiations. “The discussions and due diligence are advanced.”

Repsol confirmed it had received approaches to buy part of YPF and reiterated its desire to sell part of its stake, possibly through a public offering. “Repsol wants to make it known that it has received various proposals from different companies, although none of them is firm,” it said via the market regulator in Spain.

Repsol declined to comment on CNOOC, but said of the other approach: “We’re not in any formal discussions with CNPC.”

The Chinese groups have stepped up discussions with the National Development and Reform Commission, which can block outbound investment it deems to be not in the national interest.

“The reaction at the NDRC has been positive,” said a person familiar with the discussions. “These potential deals fit the Chinese strategy to secure energy supplies.”

Repsol shares rose on Thursday but closed up just 0.1 per cent at €16.22 in a falling market.
