Automatic Projector Calibration with Embedded Light Sensors

Very slick way to project video onto arbitrary surfaces.

Oracle running under Railo

I have successfully installed Railo with the free version of Oracle XE. I have also gotten both the Oracle Thin Client and OCI drivers working. I'll let you know what I did to get each working, although, I think that the thin client is sufficient for most needs.

If you installed Oracle XE, the ojdbc5.jar driver is at:
/usr/lib/oracle/xe/product/11.1.0/client_1/ojdbc5.jar

Just copy that file to:
/opt/railo/lib/ojdbc5.jar

Your driver should work now (from the server administrator).

If you prefer to use the OCI driver, I had to get the 11g client from the Oracle website. Installing it was a bear because it required X11 and I am using Amazon EC2. Then you have to copy 3 different files into /opt/railo/libexec/

/usr/lib/oracle/11.1/client/lib/libclntsh.so.11.1
/usr/lib/oracle/11.1/client/lib/libnnz11.so
/usr/lib/oracle/11.1/client/lib/libocijdbc11.so

Hope this helps someone...
