Is this John Carmack true account? Or is it a fake one? I mean, the tweets are exactly the kinds of things that I assume John spends his day thinking about, but would he tweet it? It's almost too perfect to be a real account.

Here are some of the latest entries:

• It's a good day when you can remove an epsilon from an algorithm!
• I can’t think of any valid reason to have a SW thread locked to a particular HW thread, as opposed to a particular HW core. Anyone?
• A multi-source ultrasonic Doppler sensor seems like a good idea, the positional equivalent of rate gyros. One integration is ok, two isn’t.
• I was always disappointed when I tried to use temporal jittering to address sampling problems at 60 hz, but I need to try again at 120 hz.

It's too good.

Lots of game industry and journalism people following and interacting with that account, so it seems legit. He posted a picture of the hardware he is referencing in the 60 hz vs 120 hz tweet a week or so ago, so if it is fake they would be putting a lot of effort into it.

And I totally agree with him on that first tweet, removing epsilons does feel damn good.

I'm pretty sure that's him. One of his tweets a while back was about ID source code being put up on GitHub. Should be him.

EDIT: Here's that tweet in particular: https://twitter.com/idSoftware/statuses/164494138396508160

Yeah it's legit. I love not understanding a single thing he says.

Yeah, as others have said that is his real twitter account. Cant say that the guy does not absolutely love what he is doing.

It's real. And it's awesome. I don't understand 90% of what he says, but it's brilliant. I mean, just take this one recent tweet as an example "It's a good day when you can remove an epsilon from an algorithm!" I don't have a clue what that means, but it's clearly awesome.

I can at least somewhat decipher all of that, but temporal jitters sounds like the plot to yet another Star Trek episode involving the bending of the space-time continuum.

It's him. I know it's real because SpeedTree follows him, and SpeedTree doesn't mess around!

I'm so happy that the account is his real account. Man, what a great twitter account.
