  • But just as the horror of a daemonless boy would be nothing without the buildup of what a daemon is in the first place (you've read HDM, right?), the constant beating-you-over-the-head with the formula is necessary to appreciate what happens when the formula, bit by bit, begins to break down.

  • Just as the appearance of the daemonless boy near the end of The Golden Compass wouldn't carry nearly so much horror if we hadn't been so entrenched in daemon-hood up until that point, I think that the formulaic content of the first six Snicket books - a major point of criticism - is absolutely essential to the disorienting effect of watching the formula, bit by bit, dissolve in later books.

  • Friday, June 06, 2008 11: 57 PM by Kirk hi Scott - is there any support for using Silverlight 2 for a web service or "daemon" - like service (i.e. Windows service, but on other platforms)? as more things get stuffed into Silverlight, it seems to makes it a better.

  • Is it pronounced demon or damon? I always mumble the first syllable when I have to say it aloud.

  • The words daemon, dæmon, are Latinized spellings of the Greek δαίμων (daimon), used purposely today to distinguish the daemons of Ancient Greek religion, good or malevolent "supernatural beings between mortals and gods, such as inferior divinities and ghosts of dead heroes" (see Plato's Symposium), from the Judeo-Christian usage demon, a malignant spirit that can seduce, afflict, or possess humans.

  • Conversation I had working IT:

    Guy: I got this problem, I keep getting these emails.

    Me: Emails?

    Guy: Yeah, and I can't understand a word of them, they're all letters and numbers all jumbled up, can't make head nor tail of them.

    Me: So where are you getting these emails from?

    Guy: I don't know, they're all from a guy named Damon. I don't know who he is, I thought maybe he worked with you guys.

    Me: Damon?

    Guy: Yeah, Mailer Daemon. You know him?

    Me: Ohhhhh! That's not Damon, that's DEMON! That's way above my level, that means your computer's possessed. I'm just IT, you need an exorcist.

    I actually like to pronounce it as the Greek, 'daimon' with ai as in Thailand. This is actually the intermediate vowel between ay and ee, so it sounds all right for people who have been used to pronouncing it either way. This should be the general rule for all uses of the ae ligature (and oe is oi as in voice). If you have to choose something else, however, I'd take demon.

  • It's pronounce demon. I say dameon, though. It's considered your soul, or your consciousness. What separates man from animal. At least, that's the definition by His Dark Materials standard.

  • According to 1999 Wired Style, they made daemon into the backronym "Disk And Execution MONitor."
