Perfect wallpaper from digital photos using Linux and Netpbm

The world is full of wallpaper managers for every operating system out there. I enjoy wallpapers taken from some of my digital photography, such as this trip to Yosemite last year.

On nice modern monitors, you can really enjoy the full resolution of your pictures. Jane and I just replaced our old Viewsonic CRT monitors with [...]

A perfect night in the desert

Observing report, dark sky weekend, September, 2009, Chuckwalla Bench

The "Double Cluster" between Cassiopeia and Perseus

The Clear Sky Chart forecast for Desert Center, CA, was dark blue all night for our favorite observing site. The NOAA forecast called for a high of 99 and low of 77. Often a night like this can have uncomfortably [...]

Joy of Bridge

Mojo playing bridge on the Sea Princess

Throughout my life I’ve been something of a serial hobbyist, with a tendency to pursue a hobby obsessively until I burn out on it, or at least until the flame starts to cool. Over the years I’ve tackled ham radio, flying airplanes, gliders, motorcycling, tournament bridge, and astronomy.

(My [...]

First cruise: The Sea Princess, San Francisco to Alaska

Jane and I are in our first port of call on our first-ever vacation cruise. We’re in a coffee shop in Ketchikan, Alaska.

Photos from our first three days with Jane’s family are here.

The cruise went non-stop from San Francisco to Ketchikan, which involved two days at sea. About 36 hours of the cruise were spent [...]

Watching the Atlantis STS-125 launch

It’s been several weeks since NASA launched Atlantis to service the Hubble Space Telescope. Watching the launch, I heard several calls that made me sit up in my seat. You probably didn’t hear them. Watch it with me here:

Listen to the audio …

At 0:49 into the video, about 15 seconds into the launch, CAPCOM says [...]

Making panoramas

Moonstone Beach in Cambria, CA

I love to make panoramas almost anywhere I take the camera. There are some examples on last week’s Mojave National Preserve trip, a weekend at Moonstone Beach, and the Fremont Peak Star-B-Q.

Making them smoothly takes a little practice, so I thought I’d pass on my pointers. I use a Canon [...]

Snakes, Tortoises, and Stars

What do herpetologists and astronomers have in common?

They both like going out on new moon weekends: astronomers to find faint fuzzies, and herpetologists to find nocturnal reptiles.

Last year in October, Jane met herpetologist Hanna Strauss at an event in Mojave National Preserve, and the two of them resolved to get together [...]

Making Flash video from AVI files for JAlbum

My wife’s little point-and-shoot Canon SD870 makes some splendid video. The full-res versions are motion-JPEG files stored as an AVI. It doesn’t take very long to eat up a lot of megabytes.

It’s not very practical to share our video on a web site in its raw form. By converting the AVI video to Flash, you [...]

Messier Marathon 2009

The Messier Marathon seems like a silly exercise, but it’s certainly fun. Jane and I were introduced to our favorite dark sky desert observing site five years ago when Don Machholz invited us to join him for a mid-week Messier Marathon.

Big dobs set up for the Messier Marathon under clear steady blue skies.

We’ve logged 108 [...]

What’s wrong with Caesar’s Palace?

Registration lobby at Caesar's Palace Las Vegas

This past week, my wife and I spent four nights in a deluxe room at Caesar’s Palace in Las Vegas. I was attending TheServerSide Java Symposium, and she went along for three days of pampering and relaxing.

Caesar’s is a fine place, a grand old warhorse of the Vegas [...]
