I was just so astounded to see these unique photos in an email promotion for the Del Sol Performing Arts Organization over the last month. I like Del Sol, and if you’re in the San Francisco area you should check them out (or get recordings), but the photos caught my eye because they (and especially the one on the right of Rick Shinozaki) look so much like what I see when I get an optical migraine that it’s totally astounding.

Hosting- Rackspace on steroids and on to WPEngine (for some)
Oh man, I am asked all the time how to pick a hosting company. And although I do all my hosting in just two places now, the evolution has been interesting, and I don’t have an answer that I completely like yet. I can see that for most people, you have to go with something easy, and the domain registrars provide easy solutions – like Network Solutions and GoDaddy, for instance. But if you’re a geek and can handle your own simple installations, then a virtual private server can be a tempting idea.
Here’s my history of hosting on the Internet. [Read more…]
Even Robots.txt won’t keep the googlebot away
Well am I ever surprised! I would have thought that inserting a robots.txt file that tells googlebot to “go away” would cause it to “not index the site.”
User-agent: *
Disallow: /
Instead, I discovered that the googlebot may still spot the site and then put up a message saying that the site exists but is not indexed. i.e. the Googlebot still publicizes the existence of the site. It makes Google look like the good guys and us look like the bad guys for putting up a robots.txt. Yay for Google liberating all online information! Boo for us trying to keep our site un-indexed until we’re ready to make it public. [Read more…]
Space Shuttle Endeavour’s Last Flyover
NASA flew the retired Space Shuttle Endeavour through the San Francisco Bay Area this morning. It was a treat for tens of thousands of us who waited and watched for this very last flight of the Endeavour. It is one of four shuttles going into retirement in the form of permanent exhibits…with Endeavour ending up in Los Angeles.
Using amateur radio repeaters — there were lots of folks watching for the aircraft all along its route — I tracked the flight’s progress from Southern California up past Stockton, where it flew around the capitol building in Sacramento twice, then down the Sacramento River to the Bay Area. The craft made a pass by the Golden Gate Bridge, one around the Bay in a big loop, and then back out straight between the bridge towers. I joined hundreds of enthusiastic fans viewing from Twin Peaks (elev. 800+ ft) in the geographical center of San Francisco. We were nearly the same elevation as the aircraft, which flew between 1,200 and 1,500 feet during the entire maneuver. [Read more…]
Mars Curiosity Inspires me to Explore more Radio Data Modes
This is a way geeky night for us engineers, and somewhat akin to the 1969 moon landing in many ways. I’m watching the Mars rover Curiosity landing right now (14 minutes delayed, of course, due to the speed of light). “Parachute deploy!” they say just now. And a minute or two later I’m watching as the JPL engineers report “Touchdown confirmed, we are safe on Mars … and … Now to see where Curiosity will take us.” The largest rover and science experiment to date has landed on Mars (afternoon Mars time, actually). By the time the radio signals reached us, the rover had been there for 14 minutes. (The photo is of a wheel cover, which I guess a mechanic is going to remove tomorrow.)
