Being back in the Bay Area is fun, because I’m getting to see all my friends and family.  Of course, I’m also doing a ‘bit’ of flying.  Today, Fiid and I went with my instructor Bill Hightower on my mountain checkout flight to Lake Tahoe.  What a fantastic flight.  Fiid took a bunch of pictures and I did the flying.  The Spot track is reversed, so number 1 is the last track point.  We flew IFR from San Carlos (KSQL) to Lake Tahoe and flew the GPS approach into South Lake Tahoe (KTVL) airport.  Then we flew to Alpine Co. (M45) and then back to the Bay Area VFR.  I’m now all set to fly the Cessna 182 to Vegas. Yeah!

This evening I created an advertisement, well… I got suckered into personalizing an ad and sending it to one of my friends. Meetup.com created this cute animation, and then gives you the opportunity to personalize the message to send to your friends.  Pure genius!  The pull-downs are so seductive that it doesn’t feel so much like an ad, but rather a way to poke fun at someone who you know would get the joke.  So, I sent one message.  Yes, only one.  I’m sure everyone else is spamming the planet.

The amazing thing about this site is that it does exactly what Marshall McLuhan envisioned back in 1960.  Shown here in a TED talk by Peter Hirshberg, McLuhan comments: “If the audience can actually become involved in the actual process of making the ad, then it’s happy.” (skip to 14:30)  To describe McLuhan as a visionary is a massive understatement.  I suspect that if he had time-travelled to today and seen Facebook and MySpace he would not have been surprised.  The rest of Hirshberg’s talk is also really quite interesting.

The BBC is producing a fascinating series called “Britain from Above” that combines GPS tracking, data collection and sophisticated computer visualizations to give viewers a view of the UK that no one has ever seen.  It’s absolutely captivating to watch the planes entering and exiting British airspace, or seeing the nation’s telephone network come to life.  The Daily Mail wrote an article about the series that includes some images.

Let it be said that 2008 will be the last year that I don’t got to AirVenture in Oshkosh.  For the uninitiated, it’s the Mecca of Aviation every year.  Now that I’m an EAA member, with an instrument rating I really have no excuse not to go any more.  This year they announced the Icon, the SPOT Messenger was apparently a big hit (I just ordered one to document my flights), and an all-electric airplane flew.  Two of my friends (Lisa and Adam) were there, and apparently Esther Dyson was there.  I did not know she was into aviation.

You’re spending too much time on YouTube, aren’t you?  You’re at work, yes.  Ok, that’s probably alright.  If you haven’t been to TED, the site — cause getting into the actual event is like impossible, you’re missing out.  To start you off, watch Ze Frank’s presentation from 2004.  The Hans Rosling talk is a classic.  Jill Bolte talks about her brain.  And Johnny Lee plays with Wii.

Today I made my first contribution edit to this page on Wikipedia.  I was actually able to add some relevant content, information about the FAA’s decision to extend the expiration dates on first and third class medical certificates for pilots under 40.  Quite amazingly, looking at the history of the page I discovered an old friend of mine who, it turns out, is a flight instructor.  Small world.

An interesting presentation at Stanford’s ACM on how facebook works behind the scenes with images. It talks about Akamai (my company) a bit and mentions how they are able to off-load 99.8% of their profile picture traffic. They also discuss their server-side Cachr project which is based on the memcached project.

CAPTCHA. You’ve all seen it on web sites where they want to read an image and then type the letters to ensure you’re a person and not a computer program. Well, a couple of guys at the School of Computer Science at Carnegie Mellon University figured out how to make this annoying process into something that actually benefits humanity. Recaptcha.net helps digitize books from the Internet Archive.

I’ve now been ‘online’ in one way or the other for nearly 20 years, starting the first time I connected to a bulletin board system in Dec. of 1988. I’ve played, chatted, searched, published, expressed options, made friends, argued, campaigned for office, experimented, learned, even entered the truly bizarre world of online dating. What’s it all leading to? Well, if you recall the battle-cry of the Borg on STTNG you’ll already know ‘you will be assimilated.’ We Fell Fine is just about the only proof you’ll ever need. As far as interesting Internet experiments go it’s not completely lame. And I want you to want me is slightly surreal. Jonathan Harris & Sep Kamvar are sickly creative.

This week could be one for the Space history books…

Atlantis (STS-122) is scheduled to land on Wednesday. There are four possible landing opportunities, two at Kennedy (preferred) and two at Edwards AFB. As you may know NASA likes to avoid landing the Shuttle at Edwards because then they have to load up the orbiter onto the specially-equipped Boeing 747 and haul it back to Kennedy, which looks cool, but delays the next scheduled mission for that Shuttle. Now, typically if the weather at both these locations is unfavorable due to storms or high-winds then NASA will delay the landing and try again the next day. They have enough oxygen and fuel to make it to early Friday if necessary. But, here’s the catch…

Last week President Bush authorized the DoD to attempt to destroy a doomed super-secret spy satellite, designated USA 193, that is expected to tumble uncontrolled from orbit within the next few weeks. The U.S. Navy will try to destroy the satellite prior to its reentry by slamming a ship-fired SM-3 into it.

from Sky and Telescope:
“Apparently, DoD computer models have shown that, if left alone, more than half of USA 193’s roughly 5,000-pound mass would survive the atmospheric plunge and reach the ground. In particular, there’s a 20-inch diameter tank containing about a half ton of the highly toxic propellant hydrazine. So the decision was made to break up the satellite if possible.”

The DoD has determined that Thursday is the first possible day to start letting the Navy begin ‘target-practice’ and let SM-3 ‘meet’ USA 193. And this brings up the interesting question of, do you really want to be launching a kinetic warhead into space to break-up a spy satellite into thousands of little bits the same day 7 relatively un-armed Astronauts are attempting to guide a rather fragile glider back to Earth. Now, admittedly the Earth’s atmosphere and Space are pretty big, but if something were to happen it would look rather… what’s the word… stupid.

NASA is remaining surprisingly mum about the conflict, but I bet NASA really, really, really wants to get out-of-the-way and land Atlantis on Wednesday. And that brings up the interesting possibility of the fifth landing opportunity on Wednesday. That’s right, the fifth. If the weather at both Kennedy and Edwards is unfavorable, then Atlantis can also land at White Sands, NM. The last and only time the Shuttle has landed at White Sands was in 1982 when Columbia (STS-3) landed there during an R&D flight. But as it stands White Sands is now prepping for a possible landing.

Admittedly, this landing of Atlantis is not going to be as exciting as Jerry Bruckheimer could make it, and it will not end in Bruce Willis sacrificing himself to blow up an asteroid, but bringing in a Space Shuttle for a combat landing just before you start shooting at an out-of-control toxic spy satellite is about as exciting as it gets.
