      View on capitalism as the cause of economic down turn. Brief talk on history of communism and socialism and why it failed. Seems to support socialism
  • Third, it wasn’t because communist countries rejected markets that they failed. It was because they backed off of Marxist-Leninist principles, and conciliated with capitalism, that they collapsed.
  • Second, communism had not a moment’s rest from attempts by the capitalist countries to destroy it.

  • communism arose under inauspicious circumstances.
  • apitalism being too weak to block the rise of revolution meant that the revolution would have to take hold in a country where the working class was small and the industrial base — necessary to progress toward a communist society of plenty — was rudimentary at best
  • gainst the far right’s explanation that immigration is the cause of joblessness, the left could point out that insecurity is caused by the failure — indeed refusal — of capitalism to offer secure employment to all; that the solution is to transcend the capitalist system; and that where it has been transcended in the past, secure employment has been made available to all, along with guaranteed healthcare, security in old age, subsidised housing, free education, and a raft of other mass-oriented reforms
  • There is no freeloading in a socialist society. Work is an obligation
  • capitalism is the cause of your problems
  • Sweden, often celebrated as a social democratic paragon and held out as an attractive alternative to Marxist-Leninist-style socialism, has proved no less vulnerable to outbreaks of recession-induced xenophobia than bastions of neo-liberalism have
  • Attributing the demise of really-existing socialism to internal failings, and ignoring seven decades of efforts to exterminate the communist challenge — a practice of both the right and left — is a peculiar form of blindness.

    I stumbled upon this website the other day. Its an article site with a bunch of hired authors. "Wait--hired authors!!" You say, in righteous defense of the open "wiki" model. But the cool thing about hired authors is that they are all viewing and rating each other's articles. Hence, "helium," the best articles rise to the top. I mean who decided that it was the best system to have bored 40 year olds living with their parents as the main source of information. (Let's be honest, those wikipedia articles didn't write themselves.) The good thing about a paid workforce is that there is a sense of pressure under writing the articles. Their business model is in and of itself an "invisible hand." Anyways, i thought it was a cool idea. Voila.

  • the Jacquard loom used a system of hooks and needles to lift the appropriate warp threads. The pattern was stored on a collection of thick paper cards perforated with rectangular holes. As the fabric was woven, the hooks were held stationary by the surface of the card. However, whenever a hole was encountered, a hook would be allowed to pass through to lift its thread. By stringing together a large number of cards, an intricate pattern could be created.

      I feel like one of the reasons for this is because there is so much required of individuals.Whether it is our jobs or our education, we have to work constantly in order to survive. There is little or no leisure time until you have earned it. Would it be possible to live in a type of economic system that would allow each individual the ability to choose based on their own judgement of when to do work for others and when to do work for himself? That would be awesome!

    I'm not sure that this is how most people use tumblr, but it occured to me that searching for images through a blogging service where people are handpicking these images may be a better system. How many of us have looked something up through google images with sheer frustration at the lack of variety of images? Maybe I'm the only one. All I'm saying is that you should try opening up tumblr, plugging in a word like "mountains" or something and see what rolls out. Keep in mind that an extract of the blogger's text entry is displayed with the image, so it is not a legitimate "image search." But I really feel that this way of people deciding what images should be showing up is a great one. That is all. Also--Don't get too distracted by the huge sign up form in the middle of the page.

  • 935   First practical radar British scientist Sir Robert Watson-Watt patents the first practical radar (for radio detection and ranging) system for meteorological applications. During World War II radar is successfully used in Great Britain to detect incoming aircraft and provide information to intercept bombers.
  • 1937   Jet engines designed Jet engines designed independently by Britain’s Frank Whittle and Germany’s Hans von Ohain make their first test runs. (Seven years earlier, Whittle, a young Royal Air Force officer, filed a patent for a gas turbine engine to power an aircraft, but the Royal Air Ministry was not interested in developing the idea at the time. Meanwhile, German doctoral student Von Ohain was developing his own design.) Two years later, on August 27, the first jet aircraft, the Heinkel HE 178, takes off, powered by von Ohain’s HE S-3 engine.
  •   1939   First practical singlerotor helicopters Russian emigre Igor Sikorsky develops the VS-300 helicopter for the U.S. Army, one of the first practical singlerotor helicopters.
