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 in […]

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 “Bypass […]

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 20D […]

Snakes, Tortoises, and Stars

Photos and video found here

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 again […]

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 can […]

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 and […]

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 strip. […]

“Bean Validation” Emmanuel Bernard

Registration lobby at Caesar's Palace

Notes from TheServerSide Java Symposium March 2009

What’s the point of a bean validation framework? I’ve been wondering that for a while now. Emmanuel points out that it’s mostly to keep from repeating yourself in code.

Validation itself is obvious … keep crap out of the database, apply constraints to data fields, give […]

“Building Next-Generation Web Applications with the Spring 3.0 Web Stack” Jeremy Grelle

Notes from TheServerSide Java Symposium March 2009

Jeremy is going to help us battle complexity in web applications. (It’s hard to find a web framework that isn’t its own layers of complexity.) He’s the lead for Spring Faces, Spring JavaScript, and a JSF 2.0 expert group member, and he’s a former “rock star.”

The Spring Web stack is […]

“Building Server Platforms with OSGi and Equinox” Rob Harrop

BIRTExchange at TheServerSide (not related to the talk)

Notes from TheServerSide Java Symposium March 2009

Rob wrote his talk for EclipseCon which is next week, so we get an early peek. He’s the lead developer from dm Server at SpringSource.

I’m a complete noob to OSGi, so I’m not familiar enough to see what’s really important or significant […]
