IRC will get you the fastest response, and email will get me very fast, real mail is sort slow, and calling my cell phone is slowest because I don't have one, but I do have VoIP service so you could call me if needed.
Yay email. Email is good. It's even better when there are good subject lines. Email me about anything. I'll get it fast.

I exist as darst on irc.oftc.net. I monitor my IRC link basically anytime I'm near an Internet connection, which is fairly often. This is definitely the way to try to contact me for real-time communication.
To make it easier for people to talk to me, I did a quick install of a java IRC client (PJIRC, it's GPL). If you go to the link below, it will directly contact me. I'll probably answer right away.

Note that there are many other IRC clients, any will work. This is just more convenient for some.
Ask me...
I don't have a cell phone, but I do have VoIP service which you can call me at, and I can call you from. I can answer or call from either work or home, so that's basically everywhere important. If you find a way to do arbitrary precision arithmetic (this shouldn't be too hard), you can call me at cuberoot(270497419345813271624036205553). Alternatively, just ask me for the number.
I am (my three initials)@zgib.net (Google Talk/Jabber, the preferred method), blah on AIM and blah@hotmail.com, and. Your task is to determine blah. If you use IRC, I prefer that.
blah is sqrt(C99B763D3DAAE900) (but lowercase)
The input is in base 16, and the output should be in base 16 as well. It starts with an "e".
If you want, just ask me and I'll tell you.
