Vietnamese high school kids can pass Google interview

This is the fertile ground envisioned by Nicholas Negroponte of OLPC, but it's going to disappear.

It mirrors my experience in 1990-1995 in Hong Kong. Affordable computers. Rampant piracy. And ... most importantly, unreliable internet (14.4K, anyone?), and lack of entertainment.

When children have access to computers but lack entertainment, they will find entertainment on the computer itself - a hacker's delight.

This phenomenon WILL dissipate once they have access to broadband internet, plenty of entertainments, and stepped-up piracy enforcement.

HP's Memristor tech - better than flash?

It is fundamental because it models a physical phenomenon elegantly.

Memristor is fundamental in the context of describing the phenomenon observed by the HP researchers. Without this mathematical construct, it will be cumbersome to model memristor with a combination of capacitor and voltage-controlled voltage source. Chua's definition simplified the model for the HP researchers and freed their minds so that they can find useful applications for this newly discovered device.

Perhaps this is a confusion between "fundamental" and "linear time invariant". http://en.wikipedia.org/wiki/Passivity_(engineering)

It is true that memristor is not linear time invariant. However, being a device that does not produce energy, it qualifies as a passive device. Nonlinear devices always open doors for new applications, just like in optics.

PS3 update to rid all consoles of Linux support

Sony is trying to protect the AACS keys.

Someone in a piracy-harboring nation might have already started a project.

Why isn't there a red-pill option? Permanently remove all the content protection keys from the PS3 and make it a clean Linux box.
