I’ve been trying to tune up some of my telescopes for the upcoming Mars event. In late August, Mars will be closer to the earth than it has been in all of recorded history. While surfing around, I noticed that there was a Python package called PyEphem which provided Python bindings for the popular Xephem [...]

Well, it’s that time again, I’ve got another production credit on another movie. Pixar is releasing Finding Nemo, starring a young clownfish named Nemo and his dad Marlin. Nemo is captured by divers and put in a fishtank in a dentist’s office, and the movie highlights their parallel adventures to be reunited. I can’t be [...]
The problem with the web is that sometimes you hit a website that drags you off into a direction completely unrelated to anything you’ve really considered before. This happened to me most recently when I encountered a site which described the work of John Logie Baird, a Scottish engineer who designed a television system that [...]
Well, I didn’t try to take any pictures of the lunar eclipse, but I did try to take a picture of the post-full moon using the maximum zoom setting on my Nikon 4500. Exposure was for 1/60 second at f/5.1, and was a simple handheld exposure. The image was cropped from the normal 3.8 megapixel [...]
Digital Photography For What It’s Worth is a great webpage with many terrific hints for the digital photographer, including a rather interesting page on infrared photography with digital cameras.
I have to admit that I’m a pretty big fan of CSI. Not the crappy new CSI: Miami, but the original one. It gets Tivo’ed at my house all the time, as well as many CourtTV shows like Forensic Files. The previous blog entry got me thinking about aquiring fingerprints clandestinely, and I thought about [...]
Bruce Schneier is the author of Applied Cryptography, the incredibly useful encylopedia of modern cryptographic algorithms. He also publishes the Cryptogram, an electronic bulletin involving computer security, privacy and cryptography. Today I received the latest issue, which includes an article on fooling biometric fingerprint scanners. Tsutomu Matsumoto tried several techniques to create phony fingers that [...]
Since Carmen and I both just got new digital cameras, we are taking a lot more photos and Carmen wanted me to create a simple way for her to put her photos on the web and to organize them. I used some of the ideas that I got from writing my primitive blosxom clone, and [...]
I love the new Nikon, and have had some fun playing around with it. I used Panorama Factory to stitch together 11 images to construct a view of Pixar that is 16500 pixels wide. Unfortunately, that turned out to be a 77 megabyte TIFF, so I thought I’d just give you the smaller 2048 pixel [...]
CK’s Digital Camera Page has a really nice set of manuals for certain Nikon cameras, including my new Nikon 4500.
I’m planning an anniversary trip to Paris with the missus, and decided that it was time to retire our aging Kodak 210+ camera and buy something new. We decided that we would each buy each other a new camera: I got Carmen a Canon A70, a very nice 3M pixel camera that is both small [...]
SuperDeluxo4 wgets and curls is a nifty site which logs interesting things that you can do with the command line tools wget and curl. Nifty.
