I feel a bit silly pointing this out, but all that stuff about hexes and witches and everything mystical in the article is just a playful framing story. Aphyr in all likelihood is not an occultist or mystic, and is just writing playfully (and somewhat ironically) about technology and modern interviews. The playful conflation of mystical incantations and writing code is an old hacker tradition (other playful traditions: mixing buddhism and zen with coding, and writing apocryphal parables about it). Also, it should be noted that being an atheist doesn't preclude being interested in the history of religion, folklore literature and traditions, or even entirely fictional religions.

Of course, maybe your comment above was playful and ironic as well, in which case I missed the point :)
