Arthur Clarke is Dead

Arthur Clarke, author of a number of important science fiction books, member of the British Interplanetary Society, co-inventor of marvelous technologies, and accomplished scuba diver, has died at the age of 90, in his long time home of Sri Lanka.My favorite book of his was Childhood’s End, which I read when I was about 12.

Well said.Clark said in an interview many years ago that the reason he lived in Sri Lanka is because it is one of the two spots on the earth over which dead and dying satellites tended to congregate (owing to some gravitational anomaly).Here is the web site of the Arthur C. Clarke Foundation.

We tell that to non-Linuxers because they wouldn’t understand the real reason. And when we say those false reasons enough, we might even start to believe them ourselves.But deep underneath, the real reason remains.We use Linux because …
