Today I altered Gallery so that it displays camera metadata as well as have Shutterfly print that metada on the back of prints. I posted the modification on the Gallery discussion board.

To me metadata is one of the coolest things about digital cameras. I would love to see GPS data included as well. I'm sure it won't be too long. Either way, having my Gallery pictures say things like “2/25/2003 17:33:54 146mm 1/30 f/3.0” under them is very cool.

I had some harsh words for Snapfish in a recent diary entry. I since heard back from them that the color distortion I experienced was a fluke. I may try them again, but so far I've had great luck with Snapfish. Their customer service has returned my emails quickly and competently and the image quality is great.

I implemented Monte Carlo Localization for my Robotics class. It's a great example of a simple idea that works really well. In the process of that I discovered that math.h includes the gaussian error function. Also, I learned that Maple can generate C code. Look at Maple's codegen page for details.

Last week I attended a LinuxMovies meeting, which was interesting. It was interesting to hear about CinePaint and it's forking from the GIMP. While it's too bad that the projects are diverging, it really sounds like the tools want to be too different. Perhaps low-level things technically could be shared, but doing so probably isn't in the best interest of the projects as a whole.
