I was watching this Bloomberg video the other day featuring Shawn Carolan, the venture capitalist who backed the Siri electronic personal assistant startup then sold it to Apple. His was the closest I’d heard to a technical explanation of how Siri works and it surprised me because it sounded a lot like technology I remembered from years ago at Excite, the long-defunct search engine. Please look at the video and then meet me in the next paragraph. The part that excited me (no pun intended) is about four minutes in.
Okay, he said they used linguistic techniques to map blocks of words against 10 possible domains of expertise to figure out what the heck you are asking Siri to do, with the real […]

Steve Ballmer has always been nice to me. I can’t say we have much of a relationship, but the half dozen times I have interviewed him have always gone well and he tries to please, which I appreciate.

This week I’m at NASA’s Green Flight Challenge in our new home town of Santa Rosa, California. It’s a contest for efficient flight using alternative energy that I’ll be writing more about later in the week. Much of the $1.65 million in prize money comes from Google, the subject of this column. I’ve been giving a lot of thought to Google’s strategic path under once-and-future CEO Larry Page and think I’ve got a couple things figured out. Google is right now in the process of changing, well, its process. Page is rebuilding the company but not doing a very good job of explaining himself, so I’ll just have to handle that here.
I seem to be writing a lot of these What the heck was that? columns explaining recent news events. This time it is the firing of Carol Bartz as CEO of Yahoo. I’m not here to defend Bartz, whom I would have fired long ago (or more probably not hired in the first place), but I want to make the point that for all her failings, Bartz was mainly fired for being a hardass. It’s not what she did or didn’t do as much as her style while doing it.
