  • ArcGIS Server Cloud Licensing
    Hurricane Katrina’s Eyewall Animoto is a startup company that had to spin up 5000 Amazon EC2 instances in one week. They started on a Monday with 50 instances and by the end of the week they had 5000. Then a few weeks later they were back down to about 100. If they were using using Oracle […]
  • zigGIS and ArcGIS 9.3
    Now that ArcGIS 9.3 has been finalized, I have finally gotten around to testing zigGIS 2.0.1 with it. While the source code is available, I wanted to test the unmodified binary distro.

    From CDC.

    … only when Double.IsNaN(double d) returns true, [Update:] or when it is not equal to itself.
    I guess this makes sense, just because two things aren’t numbers doesn’t necessarily mean they are equivalent. if (double.NaN != double.NaN) Debug.Print("IEEE rules!");
  • Gone fishing, left the building, moving on
  • Small patch for portable GIS
    Someone (thanks Bruce) has alerted me to a mistake in Portable GIS, which luckily requires a very minor patch- so minor that I am not going to release a new version now and force everyone to download it again, although it will be fixed in the next version. Basically there is a line in the […]
