Cool RetroTech, but…

The first stored-program electronic computer capable of doing useful work was the EDSAC, built at Cambridge University and commissioned in 1949. It supported research in several scientific disciplines as well as the development of software techniques until being scrapped as obsolete in 1958. There is now a project to rebuild this pioneering computer: the reconstructed version will be made as close as possible to the original, with one exception…and the reasons for the exception, I think, are perhaps more related to social history than to the history of technology.

EDSAC used vacuum tubes (valves, in Britspeak) for its arithmetical and logical functions; for memory, it used something called a mercury delay line, an idea borrowed from WWII radar technology. (EDSAC=Electronic Delay Storage Automatic Calculator.) information to be stored was introduced at one end of a tube of mercury, down which it traveled in the form of pulses of sound. About 1 millisecond later, at the other end of the tank, the pulses were picked up, amplified, and emitted again at the starting point, with the whole train of information bits in the line thereby being kept in continuous circulation as long as the power was on.

Can you guess how the reconstructed EDSAC is going to differ from the original version?

Author Appreciation: Rose Wilder Lane

I got a Kindle a few months ago, and have been very pleased to discover lots of old and largely-forgotten but very worthwhile books available for download, often for free or for 99 cents. In this and future posts, I’ll be giving some focus to these neglected but worthy books and their authors.

Rose Wilder Lane, born in 1886 in the Dakota Territory, was the daughter of Laura Ingalls Wilder, author of the “Little House on the Prairie” books. Lane is best known for her writings on political philosophy and has been referred to as a “Founding Mother” of libertarianism; she was also a novelist and the author of several biographies.

In her article Credo, published in 1936, she describes her political journey, beginning with the words:

In 1919 I was a communist.

The Great Texas Pig War of 1841

(Another in my historical trivia posts – this is a cross-post from my book-blog. The Pig War features in my latest book, Deep in the Heart … along with a lot of other relatively unknown mid-19th century trivia.)
The Pig War was not actually an honest-to-pete real shooting war. But it did involve a pair of international powers; the Republic of Texas, and the constitutional monarchy of France. And thereby hangs the story of a neighborhood squabble between a frontier innkeeper and a gentleman-dandy named Jean Pierre Isidore Dubois de Saligny who called himself the Comte de Saligny. He was the charge d’affaires, the representative of France to the Republic of Texas, arriving from a previous assignment the French Legation in Washington D.C. He had been instrumental in recommending that France extend diplomatic recognition to the Republic of Texas, but one might be forgiven for thinking that some kind of 19th Century Peter Principle was at play . . . for Dubois turned out to be terribly undiplomatic.

To The Lifeboats

Pretty damned ironic, that the Costa Concordia disaster happened almost exactly a hundred years after the Titanic. It’s not all that often these days that a European/American flagged passenger ship becomes a catastrophic loss to their insurance company although it happens with dispiriting frequency to inter-island ferries in the Philippines and hardly any notice of it taken in Western newspapers. The contrasts and ironies just abound; fortunate that the Costa was so close to land that some passengers were able to swim to safety, and that rescue personnel were at the scene almost before the air-bubbles from the sunken half of the ship even popped to the surface.

“You may ask yourself, well, how did I get here?”

Commenter Lynn Wheeler writes at zenpundit:

“….Boyd would comment in the 80s that the approach was having significant downside on American corporations as former WW2 officers climbed the corporate ladder, creating similar massive, rigid, top-down command&control infrastructures (along with little agility to adapt to changing conditions, US auto industry being one such poster child).”

Wheeler’s comment reminded me of the following post that I had meant to blog earlier:

One occasion in particular in the late 1970s brought this home to me. McNamara had come to one of our staff meetings in the Western Africa Region of the World Bank, where I was a young manager, and he had said he would be ready to answer any questions.
 
I felt fairly secure as an up-and-coming division chief and a risk-taking kind of guy. So I decided to ask McNamara the question that was on everyone’s lips in the corridors at the time, namely, whether he perceived any tension between his hard-driving policy of pushing out an ever-increasing volume of development loans and improving the quality of the projects that were being financed by the loans. In effect, was there a tension between quantity and quality?
 
When the time came for questions, I spoke first at the meeting and posed the question.
 
His reply to me was chilling.
 
He said that people who asked that kind of question didn’t understand our obligation to do both—we had to do more loans and we had to have higher quality—there was no tension. People who didn’t see that didn’t belong in the World Bank.

This too from a speech by Robert McNamara, “Security in the Contemporary World”:

The rub comes in this: We do not always grasp the meaning of the word “security” in this context. In a modernizing society, security means development.
 

Security is not military hardware, though it may include it. Security is not military force, though it may involve it. Security is not traditional military activity, though it may encompass it. Security is development. Without development, there can be no security. A developing nation that does not in fact develop simply cannot remain “secure.” It cannot remain secure for the intractable reason that its own citizenry cannot shed its human nature.
 

If security implies anything, it implies a minimal measure of order and stability. Without internal development of at least a minimal degree, order and stability are simply not possible. They are not possible because human nature cannot be frustrated beyond intrinsic limits. It reacts because it must.
[break]
Development means economic, social, and political progress. It means a reasonable standard of living, and the word “reasonable” in this context requires continual redefinition. What is “reasonable” in an earlier stage of development will become “unreasonable” in a later stage.
 

As development progresses, security progresses. And when the people of a nation have organized their own human and natural resources to provide themselves with what they need and expect out of life and have learned to compromise peacefully among competing demands in the larger national interest then their resistance to disorder and violence will be enormously increased.

Think about this in terms of the “armed nation building” of the past decade or so and in terms of successive Clinton, Bush, and Obama administration policies. Really not that much difference if you look at it in terms of securing stability through development – armed or otherwise. Not a novel observation in any way, but bears in mind repeating as the 2012 Presidential campaign continues its “running in place” trajectory….

Update:“Running in place” and “trajectory” don’t really go together, do they? Oh well. You all know what I mean….
