Here is an article that clarifies some intersting points about the Linux kernel and its development: what is it used for, how it is developed...

The extreme ultraviolet LLC, a joint development effort charged with developing next-generation chip-manufacturing technology, recently built its first chip-manufacturing machine using the extreme ultraviolet lithography (EUV) process.

You don't need a mouse. You don't even need a keyboard. IBM's newest ThinkPad translates pen-and-paper notes to pixels. It's worth seeing it.

It is not really a news, but rather something amazing. American researchers have developed a robot that is able to "eat" to find its energy. The robot is thus able to run 15 minutes by eating a single ordinary cube of sugar...
