I've mentioned before that I keep a running list of Microsoft codenames; it's one of my favorite home-grown reference tools. That list is now available to you in the form of a handy PDF.
The "All About Microsoft" CodeTracker is a chart I'll be updating every month. If you're a Microsoft customer, partner, analyst, competitor (or even employee), you might find it useful.
Here's Version 1.0 of the CodeTracker, hot off the presses. The best part? It's free.
And while I'm making public-service announcements, if you'd like to get posts from "All About Microsoft" in e-mail form (hourly, daily or weekly), you can subscribe here.
