Hawking Considers Computer Viruses Life

A living being like you or me usually has two elements: a set of instructions that tell the system how to keep going and how to reproduce itself, and a mechanism to carry out the instructions. In biology, these two parts are called genes and metabolism. But it is worth emphasising that there need be nothing biological about them. For example, a computer virus is a program that will make copies of itself in the memory of a computer, and will transfer itself to other computers. Thus it fits the...

 A Minority of Users Account for Majority of Online Comments

In July, NPR.org recorded nearly 33 million unique users, and 491,000 comments. But those comments came from just 19,400 commenters, Montgomery said. That's 0.06 percent of users who are commenting, a number that has stayed steady through 2016. When NPR analyzed the number of people who left at least one comment in both June and July, the numbers showed an even more interesting pattern: Just 4,300 users posted about 145 comments apiece, or 67 percent of all NPR.org comments for the two month...

 Seeing Organizations as Biological Systems

There’s a continuing struggle between complexity and robustness in both evolution and human design. A kind of survival imperative, whether in biology, engineering, or business requires that simple, fragile systems become more robust. But the mechanisms to increase robustness will in turn make the system considerably more complex. Furthermore, that additional complexity brings with it its own unanticipated failure modes, which are corrected over time with additional robust mechanisms, which ...
