A Mote of Dust Suspended in a Sunbeam
Last week I set my laptop's background to a picture of the back-side of the Voyager disk. I had just read a biography of Frank Drake, which described the process of creating the image for Pioneer and the media for Voyager. Drake said it was one of the highlights of his life. This was just a few days shy of tenth anniversary of Carl Sagan's death.
Dec 20th, 1996. I don't remember the day, but I was perhaps busy working on some DMK project. I think I wasn't long at DMK; I recall my date of hire because I was nervous to tell my new boss I couldn't start when she wanted me to because I was going to spend the weekend in the desert. Carl Sagan's passing probably got washed up in the new job, and the coming Winter Solstice family gathering.
But I believe my first contact with Sagan was stumbling upon a book in my parent's library-- Cosmos. Of all the amazing things in that wonderful book, I remember most of all two chapters. The Drake equation and Nuclear Winter. An imminent danger of ending all known life. A hope of finding intelligent extra-terrestrial civilizations. Thinking back on those days makes the threats of today, and our hopes, seem trivial.
Sagan died too soon; he still had much work left to do.
Tomorrow marks the 10th anniversary of the death of a hero. Let us remember him, and do our part to fan the sparks he ignited.
Thank you, Carl Sagan. May your memory deliver us from our demon-haunted world.

Now this is high-fucking-tech...
Duct tape and bailing wire pretty much literally, so endoscopic tools with embedded six degree-of-freedom sensors (Ascension Tech). The magnetic tracking isn't without some headaches, but so far I'm pretty impressed with the precision. As expected metal screws with them, but a bit unexpectedly, the accuracy varies dramatically depending on where in the magnetic field volume the sensor is-- get too close to the emitter and all is lost.
Ah, a puppy in the window...
Only in SoCal...
Clinton Speaks
Clinton spoke in the UCLA sculpture garden for a whole twenty minutes or so to support Prop. 87 (it's a bit old now). Although I'm pretty pro-Clinton, and quite in-favor of taxing the hell out of corporate oil, I his speech didn't exactly incite me toward drastic actions. Still, it was cool to see him in person, if only from a mile away.
