This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Actually, "mojarra" is the name of a fish. It's the code name for the JSF2 Reference Implementation, and according to an interesting webpage I ran across, apparently the primary reason it was chosen what that they didn't thing "Reference Implementation" was a cool enough name. Plus, presumably, like other code-named projects, it indicates a specific version of the product, just as the code names for the various different Java versions do.
