Geotagging: The Trackback!

My first trackback! I haven't ever really done this, thought it might be a good time to try it out since I've just put in a post about geotagging.

Stacy and Brian's Hikes and Bikes: Life of a Geolocated Blog Post

Geotagging works!

See my first geotagged album from Pt Reyes.

I got a Garmin Vista HCx, after reading quite a few reviews etc this seemed like a good unit for general use. I followed directions I had found somewhere on the web. I don't have a reference to where I'd gotten started, but here's a very detailed set of directions. I sync'ed the camera and GPS clocks, turned on logging, and went out for a hike. On return I got the GPS data out of the unit, and produced a .gpx file from Garmin's software. I then added GPS coordinates to my Canon .CR2 raw files using gpicsync. They key here turned out to be setting the timezone. The GPS data is in UTC, and the camera timestamps in local time. I used a timezone of -7, which corresponds to PDT. I then processed the .CR2 files and exported them as .jpg files. Picasa didn't recognize the GPS coordinates, however. Turns out Picasa is quite picky. The solution is again the the directions I've cited above: see Markus's comment on fixing the GPS exif data using exiftool. Once that's done, Picasa recognizes the coordinates. The final step is to upload the geotagged photos to Picasaweb. Before uploading, go into the Picasaweb settings, and select "Use exif location information". Then upload the photos, and you have a geotagged online photo gallery.

To update or not to update

I was recently considering updating my desktop with more RAM. The cost of adding 2GB of RAM is about $120. The cost of getting a new (or slightly used) desktop, with a faster processor and better graphics card, with 2GB of RAM, is about $600. So, is it worth spending money to get 2GB of RAM? The downside was that such a new desktop would likely come with Vista, and would wholly defeat the purpose of getting a newer machine: improving performance. Getting a mac would in the long run be much more of a bargain. But then it becomes worthwhile to get that 2GB of RAM. I settled on getting 1GB for about $60. I think I made the right choice.

Photography failures

I've been trying to learn to take a good photograph. I've joined the Martin Bailey Photography Podcast forums, and have posted some images. I've gotten valuable feedback, some positive, all of it constructive. There is a downside to getting good feedback: all those photos that I thought were good now don't look so hot. We were out today at a lake. I tried photographing birds. I'm not particularly happy with the outcome. The sad part is that I haven't even looked at the photos yet! I think I'm just feeling pretty negative about myself right now.

So much I want to do, so little time to do it all. Will I really get any good with my camera? I do want to.

New FReT nearly done

I've finished testing FReT on Allegro CL, OpenMCL, and SBCL. I've been sloppy releasing versions of this software in the past, and am determined to not have that happen again. Tomorrow I'll write up release notes, package it up and put it up on download. I doubt this software has any users. Even I haven't really used it on any of my projects, a state of affairs I shall address now that I have the last essential usability related detail in place: execution through asdf.
