HACK Grace Hopper Explains Nanoseconds to Letterman Rear Admiral Grace Hopper is famous both as a computer pioneer and for, at the time of her retirement (at age 79), being the nation's oldest active military officer. Hopper worked on early computers, and is widely credited with popularizing the term "computer bug" after she found a moth stuck inside a relay in Harvard's Mark II computer in 1947. (Thus "debugging" became the term for fixing computer problems....) You can see the first computer bug (they kept the moth!) at the Smithsonian, in the American History museum. In this 1986 interview with David Letterman, Grace Hopper displays her grace and wit, and explains the concept of a nanosecond, using Bell System telephone wire cut into 30cm lengths -- 30cm is the maximum distance light can travel in a billionth of a second. "When an admiral asks you why it takes so damn long to send a message via satellite, you point out to him that between here and the satellite there are a very large number of nanoseconds. (Via Waxy.)
STUFF The Nerd Handbook A nerd needs a project because a nerd builds stuff. All the time. Those lulls in the conversation over dinner? That’s the nerd working on his project in his head. It’s unlikely that this project is a nerd’s day job because his opinion regarding his job is, “Been there, done that”. We’ll explore the consequences of this seemingly short attention span in a bit, but for now this project is the other big thing your nerd is building and I’ve no idea what is, but you should. At some point, you, the nerd’s companion, were the project. Regarding gender: for this piece, my prototypical nerd is a he as a convenience. Understand your nerd’s relation to the computer. First, a majority of the folks on the planet either have no idea how a computer works or they look at it and think “it’s magic”. The nerd has based his career, maybe his life, on the computer, and as we’ll see, this intimate relationship has altered his view of the world. Your nerd has control issues. Your nerd loves toys and puzzles.
