The vernal equinox happened about two hours ago. Typical of this time of year, though, it's below freezing this morning in Chicago. Nature nerd Naomi has more from the wilds of northern Lake County.

Of interest to possibly no one, for the last two years I've worked on the innards of my flagship demo project, Weather Now. I'm now putting together a new user interface for it. The new version 3.5 UI, which you can see at http://beta35.wx-now.com/, looks a lot like the old one—for now.

So what's new? I've rewritten from scratch the core framework, geography and weather code, and the basic UI framework. The beta (version 3.5) looks nearly identical to the current (version 3.1) application, except that the trained eye will notice new features where the ground-up re-write peeks out.

Sometime before the end of July, I hope to finish the next version (4.0), which will have an entirely different database structure. (Version 3.5 uses the same database as the current version through a façade.)

Exciting? Probably not. But it's how I keep my saw sharp.
