Unfortunately, attempting to provision on a fresh Ubuntu 12.04 install with the following additional packages: build-essentials python-software-properties build-essential libacl1-dev python-dev libldap2-dev pkg-config gdb libgnutls-dev libblkid-dev libreadline-dev libattr1-dev openssl (please note these pre-requisite are not documented in the wiki) gives the following error: "libkdc-policy.so: cannot open shared object file: No such file or directory" and I cant get an answer as to where to find or build this module or find such info in a web search. All in all, it has been a very frustrating experience.

According to their bug report on it, it was fixed in a beta release recently...https://bugs.launchpad.net/ubuntu/+source/samba4/+bug/887537

Lets be ridiculously generous and assume a scramjet boost phase could lift you to 155 km at mach 18. You have only gained about 5% of the necessary kinetic energy needed for LEO

Pardon my pointing this out, but NASA's got another idea on boosting...

Hearing it was mechanical in nature made me call bullshit before I even saw the video.

A gyroscope flywheel is mechanical, yet would serve such a purpose. Mechanical gyros are used in spacecraft and aircraft.

Did you just call DICOM proprietary?

Technically correct. It *is* a copyrighted standard, with the copyright being held by the National Electrical Manufacturers Association. When defining proprietary software as "computer software licensed under exclusive legal right of the copyright holder", this standard would fall into that category.

Meet DARPA's New Militarized Earthworm 83

derekmead writes "Meshworm is a toughened, robotic earthworm that can crawl virtually silently at a speed of about 5 millimeters per second. DARPA wants to send it into battle. Believe it or not, the Pentagon's been working on building a robotic earthworm for a while. They tried putting one together with gears. They tried with air-powered and pneumatic pumps, but the results were bulky and untenable. Then, researchers at Harvard, MIT and Seoul National University in Korea put their heads together and designed an 'artificial muscle.' It's essentially a polymer mesh that's wrapped with nickel and titanium wire designed to stretch and contract with heat. When an electric current is applied, the mesh mimics the circular muscle system of an earthworm to scoot forward."

You've been Berkeley'ed!
