Lawrence Lessig ... speaking to a packed house at the DIA user conference keynote.

(ot) Seating nailed down at the power strip oasis. Why are there never enough outlets? airports are a special offender in this ... or, maybe i should think about a computer with more than 30 seconds of battery life.

Monday's registration deadline for the DIA user conference has passed, but you might have noticed you can still get to the registration page.

Here's the deal: there are about a dozen spots left. We'd like to fill them, but we also need to have a final-final head count for the hotel by the end of the week. So registration is going to be held open to tomorrow, Friday, June 20. That's the stone-cold, after-the-deadline deadline; we won't be able to handle on-site registrations, so if you're still juggling plans or otherwise uncertain, get in touch with us and let us know what's up no later than tomorrow.

This. Is. Hot.

Lawrence Lessig, Stanford law professor, free culture paladin, social change advocate -- man, in short, about the technology activist town -- has just been officially confirmed to keynote the upcoming DemocracyInAction Community Conference.

The conference takes place June 26-27 in downtown Washington, D.C.; Lessig will address the morning plenary on Friday, June 27th on "Change Congress". Maybe you caught him at the recent National Conference on Media Reform?

You'll find him on the expanded agenda also just released.

Did we mention (repeatedly?) that that's on top of two days' wall-to-wall Salsa training, online strategizing, and elbow rubbing with the best and brightest?

Did we mention there are only three days left to register?

Stanford professor -- and open culture intellectual -- Lawrence Lessig has made his The Future of Ideas available free online.

Essential reading for changing technology's tectonic collision with intellectual property law.

And speaking of free stuff and open-source software, the sui generis Michelle Murrain unpacks the hidden costs of "free" software at TechSoup.

A number of DIA users and friends are among scores of signatories to open letters sent to both the DNC and RNC demanding that debate footage be openly licensed to facilitate remixing, mashups, parody, commentary, and every other manner of citizen intervention free from any possible fear that some intellectual property law could be used to shut down discussion.

The letters suggest one of two solutions: place all debate footage in the public domain; or, place it under a Creative Commons license. Here's a pdf version of the letters.

That's such a damnably obvious thing to get behind that kos and Michelle Malkin are taking the same tack. And while the danger of an actual lawsuit may be scant -- "suing the anonymous person who made a YouTube skewering you during the New Hampshire primary" is a good working definition of "political suicide" -- one has to appreciate the opportunism of using the situation as a teachable moment on intellectual property for politicos.

The parties should do this, of course. But so much the better if it normalizes in some small way the idea that statues surrounding content control and distribution are not fixed on Sinai but open to discussion.
