Actually, I found a clean version on McGrath's twitter:

A bit of chapter two is up on io9:

Because no steampunk discussion should be mentioned without it:

Not that I'm aware of.  Silver (for werewolves) & cold iron (for Sidhe) are the usual culprits.

Lead works great on Daxamites, though.

I'm developing a project now where magic is described in computing terms, as the manipulation of the informational component of the planet (the "noosphere", if you are familiar with the concept).  In essence, a magician has admin access (hacked or otherwise) to reality's operating system.

IMO – there shouldn’t be a way to keep technology safe from magic in this particular game. It starts to get too WoD and munchkin if you’ve got the magic/technology détente going on.  In this game, if you want magic, you give up telephones and iPods. If you want iPods, you give up magic.

Wizpods are more Diane Duane's shtick, anyway

Here's the thing.  I'm a computer programmer.  Have been for over a decade.  That means that I not only am familiar with computers, but that I often have to "think like" a computer.

Wouldn't that suggest that I might think "Gee... I should be able to enchant my computer to protect it from magic, no matter what my teacher says."?

Here's the thing.  In cases like Star Trek & Star Wars, the officially endorsed fiction is checked and vetted by the copyright holders (Paramount & Lucasfilm), who have final say on just what gets published.

In the case of a Dresden tie-in novel, if Jim doesn't give permission, it's still fan fiction, no matter how well-written (and I've seen fanfic written better than the "official" works, like Kid Dynamo).  And even if _he_ doesn't mind, I'm willing to bet his publisher will.

Y'see, there's another aspect to this.  I'm an admin on another board, connected to a specific comics series.  And we recently had to impose a solid ban on fanfic, simply to prevent the creator from potential legal implications.  And that's in a different medium entirely. 

Picture this.  A fan writes a story where Harry becomes king of the Green Court.  In a later book, Jim has the same thing happen.  The fan decides that Jim took his idea and asks for credit (at best) or money (at worst).  And it all ends up in court.

It's happened before.  And a lot of creators are skittish.

So there are really only a few possible approaches.

1: Ban all tie-in fiction, approved or otherwise.
2: Allow certain stories, but maintain a tight hold on what happens to the characters (this is Lucasfilm's approach).
3: Allow certain stories, but decree that they are not necessarily "canon"  (see Star Trek).

I'm not sure which route Jim might take.
