Submission + - Lab Spiderman skin (

BBird writes: Interesting story from Deutsche Welle — This summer, a very unusual science project is on display at a museum in Leiden, southwest of Amsterdam. There's a piece of human skin that's been genetically combined to grow in conjunction with spider silk. This unique combination makes the skin bulletproof against a .22 caliber rifle — the standard for a Type 1 bulletproof vest. This means it can stop a 2.6-gram (0.09-ounce) bullet traveling at 329 meters per second (1,080 feet per second).

Submission + - Linus thinks virtualization is "evil" ( 1

crdotson writes: "Linus said in an interview that he thinks virtualization is "evil" because he prefers to deal with the real hardware. Hardware virtualization allows for better barriers between systems by running multiple OSes on the same hardware, but OS-level virtualization allows similar barriers without a hypervisor between the kernel and the hardware. Should we expect more focus on OS-level virtualization such as Linux-VServer, OpenVZ, and LXC?"

Submission + - Canonical Chooses Sides in the Cloud (

itwbennett writes: "In a blog post earlier this week, Canonical announced that it would be offering the Cloud Foundry Platform as a Service tool in Ubuntu 11.10. What's interesting about the announcment, says blogger Brian Proffitt, 'is that Canonical chose to go with Cloud Foundry, an Apache-licensed fully open source project that was launched by VMware, rather than Red Hat's OpenShift PaaS offering. OpenShift, which uses technology from Makara, a company Red Hat bought late last year, is not fully open source yet, so that may have something to do with it. Cloud Foundry, while open and community driven, is also a way to position VMware against Red Hat's cloud offerings.'"

Submission + - Why Teach Programming with BASIC ( 3

chromatic writes: "To answer the perennial question "How can we teach kids how to program?", we created a web-based programming environment. As we began to write lessons and examples, we surprised ourselves. Modern languages may be powerful and useful for writing real programs, but BASIC and Logo are great languages for demonstrating the joy of programming."
