Some neat things found on the web recently:

  • Ponoko - Custom Laser cutting of Plexiglas and plywood.
  • Make your circuit boards in china for cheap
  • CouchDB simple database for content management systems.
  • Mabel’s Labels - Got kids? Need to label their stuff, these look neat.
  • San Diego Fires on MODIS

    Just whipped together an animation of the San Diego Fires from some recent MODIS scenes that I grabbed from the MODIS Rapid Response System. I put the animation together using GIMP.

    United Airlines Marketing

    So, I receive this letter in the mail about once per week for the last 3 months telling me I have a balance in my United Mileage Plus account. It says I have 6,904 miles, that plus the 21,500 I’ll get from United will let me get enough for a free ticket which runs 25,000 miles, oh boy! Never mind the $60 annual fee, the 18.24% APY, I can get a free ticket baby…I can go places…see the world.

    Wait, what is that…there is an asterisk there…what does it say about that. “Based on mileage plus account balance as of 6/1/07. United Mileage Plus is not liable for mileage balance misprints.” Hmmm…alright.

    Ok, well lets go check united.com:
    united2.pngWhat’s this..my miles expired on 06/30/2007, leaving me with a balance of 0.

    So the notice I have been receiving every week for 3 months straight has been grossly misleading and too good to be true. I know the airlines are hurting….but c’mon guys lay off the deceptive marketing practices.

    Woowee…

    The blog is getting mighty impersonal with all those del.icio.us posts. Maybe that can serve as a reminder for me to post more.

    I have been hacking on a bunch of convenience code in python for the LTM (Land Transformation Model) which serves as the land use projection portion of my research. Basically just wrapping a bunch of ArcGIS functions that do what I need done and then some file manipulation and config file writing before I launch code written by our postdoc. Going to try and do some time projections for all of the state of Indiana and then go back to my Muskegon study area with the new tools to re-run the model up there. It should make things run much more smoothly.

    Quick and dirty GIS Server

    Here is a quick and dirty ArcGIS geoprocessing server. I mostly did this so that I can call ArcGIS routines from scripts on my linux box across a cluster of ArcGIS servers.

    It is not without caveats, mostly security caveats. I work in a firewalled environment and would not recommend exposing the entire arcgisscripting geoprocessing object in a non-firewalled environment, without adding some security. With the client code I am able to write scripts that work on either Win32 or Linux with the same code.

    Additionally, you will need to refer to files and directories in your scripts as they would appear to the server instance (with its windows permissions). As ArcGIS scripting routines do not directly allow the passing of GIS data to them, you will have to point to them on the server’s filesystem, geodatabase or remote ArcSDE server as you would locally on the server.
