What is music? There’s no end to the parade of philosophers who have wondered about this, but most of us feel confident saying: ‘I know it when I hear it.’ Still, judgments of musicality are notoriously malleable. That new club tune, obnoxious at first, might become toe-tappingly likeable after a few hearings. Put the most music-apathetic individual in a household where someone is rehearsing for a contemporary music recital and they will leave whistling Ligeti. The simple act of repetition can serve as a quasi-magical agent of musicalisation. Instead of asking: ‘What is music?’ we might have an easier time asking: ‘What do we hear as music?’ And a remarkably large part of the answer appears to be: ‘I know it when I hear it again.’

Batters Up: Major League Baseball Now on WordPress.com. MLB’s blogging system used to be powered by Movable Type, and about 15,000 blogs switched over to WordPress.com as part of this. It’s an honor and delight to have so many great bloggers joining the family. They’re also in good company with VIP blogs for the NFL, NBA, NBC Sports…

Panels Finished

My last panel was yesterday at 5 PM so now I’m taking as much time as I can to catch the panels that are left and learn a few things. Speaking was more stressful than I expected but most of the feedback was good. I still need to check out the web feedback though, as people are probably more candid online than when they’re shaking your hand.

Usable Security

Usable Security is a new blog about—you guessed it—the intersection of usability and security. This comes up every few weeks since I improved the error messages on the WordPress login (and bbPress) to specify which part of the login was mistaken, the username or the password. Security folks see this as a problem because you’re revealing more information but I see making the error message more generic as premature security optimization. Plenty of systems where login names are public or easily discoverable, such as Yahoo, Gmail, Hotmail, most email systems, and so forth, seem to be doing just fine.
