Zefram (legal name Andrew Main) is an autistic software engineer. He lives alone in north London. His hobbies include computer programming, linguistics, and philosophy.
Zefram's PGP public keys are available on the usual key server network. Check against the fingerprints.
His name is self-chosen, based on the Star Trek character Zefram Cochrane, who invented the warp drive. Zefram is no longer as much of a Star Trek fan as he was, but he still likes the name.
There are some pictures of Zefram. These are nowhere near being a reasonable record of his changes in appearance, and there are rarely any recent images on that page. This is probably because he has little interest in human appearances.
Zefram's fingernails used to be very long. He got asked about them so much that he wrote a FAQ, but it's out of date now. Read the whole story.
