I need a mode for my iPhone where I can leave an app running on the screen and ”turn off touch” so that I can watch what’s happening but not cause anything to happen if I accidentally touch the screen.

I have decided to call this ”fingerprint only” mode because you can touch the screen, but nothing happens.

I particularly need this for mapping and travel apps, where I want to keep the app open while I’m walking or hiking and holding the phone in my hand, but touching the screen could cause the app to fly off to different coordinates, or even to change mode or shut down. Great example is Everytrail where it tracks my movement and I frequently have it in my hand so I can watch as I walk along. Fascinating, but way too easy to touch the wrong thing and completely screw up the trip map.

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. (continue reading…)

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.)

Woohoo! The US Postal Service [USPS] comes thru! They’re in the 21st century now!

I work from a home office and I’m one of millions of people in the US who have a post office box [POB or PO Box] for delivery of business mail, rather than having it all come to my house. One of the problems with having a “PO Box” is that I have to go to the post office to pick up the mail, and things don’t arrive every day. Usually there’s mail only one or two days a week.
