+Laura Gibbs What do you think of http://lore.com/? My sister +Beth Duckles is considering it for teaching in the fall.

I can now have a synced Amazon Cloud Drive, a Dropbox and a Google Drive on my Mac. Such choices! Now where did I put that file?

Electric planes!
MSNBC reports on a #nasaaero concept for an electric-powered commercial passenger jet taking shape at The Boeing Company. Be sure to check out the video embedded in the story.

What can we learn about standardized testing from The Hunger Games?

Good idea.
Tip: Create an empty Save circle to save posts for later sharing

Great G+ circles tip from +Richard Kashdan in a comment on one of my posts: "You can mark posts you are interested in by creating a new circle, called "Save" for example, and leave it empty; i.e. don't put anyone in it. You can then save a post for later by Sharing it with the Save circle. No one but you will see that you did that, but you can later go to the Save stream on the left column to get the posts that you saved."

Kevin Kelly: So the creation of digital life was rooted in death?

Dyson: In some creation myths, life arises out of the earth; in others, life falls out of the sky. The creation myth of the digital universe entails both metaphors. ...
I did a long interview with George Dyson in the current Wired. We discuss the origins of software, and how a small band of geniuses 60 years ago made the system we are still using today. The two most powerful technologies of the 20th century—the nuclear bomb and the computer—were invented at the same time and by the same group of young people. But while the history of the Manhattan Project has been well told, the origin of the computer is relatively unknown.


Me: Because your father, Freeman Dyson, worked at the Institute for Advanced Study in Princeton, you grew up around folks who were building one of the first computers. Was that cool?

George Dyson: The institute was a pretty boring place, full of theoreticians writing papers. But in a building far away from everyone else, some engineers were building a computer, one of the first to have a fully electronic random-access memory. For a kid in the 1950s, it was the most exciting thing around. I mean, they called it the MANIAC! The computer building was off-limits to children, but Julian Bigelow, the chief engineer, stored a lot of surplus electronic equipment in a barn, and I grew up playing there and taking things apart.

Me: How did the MANIAC project get started?

Dyson: The von Neumann project was funded to do H-bomb calculations. It was a deal with the devil: If they designed this ultimate weapon, they could have this fantastic machine.

Me: So the creation of digital life was rooted in death?

Dyson: In some creation myths, life arises out of the earth; in others, life falls out of the sky. The creation myth of the digital universe entails both metaphors. The hardware came out of the mud of World War II, and the code fell out of abstract mathematical concepts. Computation needs both physical stuff and a logical soul to bring it to life. These were young kids who had just come through World War II, who could repair the electronics on airplanes and get them flying the same day, and von Neumann put them together with mathematical logicians who could imagine a universe created entirely out of 0s and 1s.

Very prescient and still relevant advice from Dwight D. Eisenhower 51 years ago! My previous "Threat Level" link quoted this speech. The whole speech is worth a read.

We've moved from the "war on terror" to "cybersecurity" as the new growth model for the military industrial complex. Wired's "Threat Level" has a good overview.

From my previous post, interesting bump when we switched to a Democrat as president.

How much confidence do you have in the U.S. President (Bush '03-'08, Obama '09-)?
